This paper presents two new route update strategies for performing proactive route discovery in mobile ad hoc networks (MANETs). The first strategy is referred to as minimum displacement update routing (MDUR). In this strategy, the rate at which route updates are sent into the network is controlled by how often a node changes its location by a required distance. The second strategy is called minimum topology change update (MTCU). In this strategy, the route updating rate is proportional to the level of topology change each node experiences. We implemented MDUR and MTCU on top of the fisheye state routing (FSR) protocol and investigated their performance by simulation. The simulations were performed in a number of different scenarios, with varied network mobility, density, traffic, and boundary. Our results indicate that both MDUR and MTCU produce significantly lower levels of control overhead than FSR and achieve higher levels of throughput as the density and the level of traffic in the network are increased.

Abstract In this prospective, case-control study, femoral neck diameter, cross-sectional moment of inertia, or section modulus was an independent predictor of hip fracture risk after adjustment for BMD. However, the contribution of each of these indices to hip fracture prediction was modest in the presence of BMD. Introduction: The relative contribution of measures of hip strength to hip fracture prediction is unclear. This study was designed to characterize the association between hip strength indices and hip fracture risk in relation to BMD in elderly men and women. Materials and Methods: Seventy-one women and 25 men ≥60 years of age, who sustained a hip fracture during the study period of 1989–2003, were selected from the prospective, population-based Dubbo Osteoporosis Epidemiology Study. These fracture cases were randomly matched for age and sex in a 1:2 ratio with nonfracture individuals. BMD at the femoral neck was measured before the fracture event by DXA (Lunar DPX-L). Hip strength indices, including femoral neck diameter (FND), cross-sectional moment of inertia (CSMI), and section modulus (Z), were estimated by reanalysis of the image files using hip strength analysis software. Results: In women, after adjustment for BMD, increased risk of hip fracture was associated with smaller FND (OR, 1.6; 95% CI, 1.0, 2.7), lower CSMI (OR, 1.8; 95% CI, 1.0, 3.2), or Z (OR, 1.6; 95% CI, 1.1, 5.1). In men, none of these hip strength indices were significant predictors of fracture risk. However, using the results in women as a prior distribution, it was estimated that the BMD-adjusted OR for FND (OR, 1.5; 95% CI, 1.0, 2.3), CSMI (OR, 1.6; 95% CI, 1.0, 2.5), or Z (OR, 2.3; 95% CI, 1.4, 3.9) was each significantly associated with hip fracture risk in men. In the logistic regression model, BMD alone accounted for 32% an...

Epigenetic alterations in the 11p15.5 imprinted gene cluster are frequent in human cancers and are associated with disordered imprinting of insulin-like growth factor (IGF)2 and H19. Recently, an imprinted gene cluster at 14q32 has been defined and includes two closely linked but reciprocally imprinted genes, DLK1 and GTL2, that have similarities to IGF2 and H19, respectively. Both GTL2 and H19 are maternally expressed RNAs with no protein product and display paternal allele promoter region methylation, and DLK1 and IGF2 are both paternally expressed. To determine whether methylation alterations within the 14q32 imprinted domain occur in human tumorigenesis, we investigated the status of the GTL2 promoter differentially methylated region (DMR) in 20 neuroblastoma tumours, 20 phaeochromocytomas and, 40 Wilms' tumours. Hypermethylation of the GTL2 promoter DMR was detected in 25% of neuroblastomas, 10% of phaeochromocytoma and 2.5% of Wilms' tumours. Tumours with GTL2 promoter DMR hypermethylation also demonstrated hypermethylation at an upstream intergenic DMR thought to represent a germline imprinting control element. Analysis of neuroblastoma cell lines revealed that GTL2 DMR hypermethylation was associated with transcriptional repression of GTL2. These epigenetic findings are similar to those reported in Wilms' tumours in which H19 repression and DMR hypermethylation is associated with loss of imprinting (LOI, biallelic expression) of IGF2. However, a neuroblastoma cell line with hypermethylation of the GTL2 promoter and intergenic DMR did not show LOI of DLK1 and although treatment with a demethylating agent restored GTL2 expression and reduced DLK1 expression. As described for IGF2/H19, epigenetic changes at DLK1/GTL2 occur in human cancers. However, these changes are not associated with DLK/LOI highlighting differences in the imprinting control mechanisms operating in the IGF2-H19 and DLK1-GTL2 domains. GTL2 promoter and intergenic DMR hypermethylation is as...

Abstract Background While risk factors of osteoporosis in Western populations have been extensively documented, such a profile has not been well studied in Caucasians of non-European origin. This study was designed to estimate the modifiable distribution and determinants of bone mineral density (BMD) among Iranian women in Australia. Methods Ninety women aged 35 years and older completed a questionnaire on socio-demographic and lifestyle factors. BMD was measured at the lumbar spine (LS) and femoral neck (FN) using DXA (GE Lunar, WI, USA), and was expressed in g/cm2 as well as T-score. Results In multiple regression analysis, advancing age, lower body mass index (BMI), and smoking were independently associated with LS and FN BMD, with the 3 factors collectively accounting for 30% and 38% variance of LS and FN BMD, respectively. LS and FN BMD in smokers was 8% lower than that in non-smokers. Further analysis of interaction between BMI and smoking revealed that the effect of smoking was only observed in the obese group (p = 0.029 for LSBMD and p = 0.007 for FNBMD), but not in the overweight and normal groups. Using T-scores from two bone sites the prevalence of osteoporosis (T-scores ≤ -2.5) was 3.8% and 26.3% in pre-and post-menopausal women, respectively. Among current smokers, the prevalence was higher (31.3%) than that among ex-smokers (28.6%) and non-smokers (7.5%). Conclusion

Sydney, Australia, has a stormwater system that is completely separate from the sewerage system. The stormwater systems are mainly managed by the 43 local councils and most of these use OSD as a means of reducing site discharge of stormwater, thereby relieving catchment flooding. Sheas Creek is an urbanized catchment that lies within the South Sydney City Council Local Government Area. Since 1984 an OSD policy has been implemented in the Sheas Creek catchment. The associated design code, like most others in Sydney, is based on discharge from individual properties without consideration of runoff from other parts of the catchment. This design code is therefore not based on a total catchment approach. The objective of this study is to assess the effectiveness of OSD in a catchment-wide manner. More specifically, to see how existing and planned OSD affects flooding in the Sheas Creek catchment, and to test the effectiveness of the current rate of permissible site discharge (PSD). The study also looks at the effectiveness of OSD when different spatial distributions are used across a catchment. The methodology involved using a computer rainfall-runoff model, OSDSAX, which is based on the ILLUDAS model. This was configured for the Sheas Creek catchment and was calibrated to match flood level data recorded during four large storm events. The model was then adopted to investigate the impact of OSD. Various scenarios were tested to satisfy the objectives of the study. Some of the results challenge conventional wisdom and these arise from catchment-specific characteristics. The analysis shows that the perceived beneficial effects of OSD are in some cases unrealistic and that catchment modelling is required to test and quantify the actual impacts for specific catchments.

This paper describes an experimental investigation of how friction factors change for spatially varied flow in sloping channels receiving lateral inflow. The results are compared with those of Beij in 1934, and it is concluded that uniform flow resistance coefficients are not always appropriate for spatially varied flow. Moreover, the common technique of assuming a constant friction factor over the entire length of the channel has been found to have little theoretical justification. The method of Keulegan in 1952 for calculating friction factors in spatially varied flow gives a better estimate, but does not explicitly take account of the lateral inflow rate or velocity. Beij's 1934 experimental data, which was used by Keulegan does not show a systematic variation of friction factor with lateral inflow rate for a constant Reynolds number although this may be due to the low flowrates used. The results of the present study indicate that the friction factor increases with lateral inflow rate for a constant Reynolds number in the experiments that included subcritical and supercritical flow conditions. A method for calculating friction factors which allows for lateral inflow is presented as a precursor to the development of a general method of evaluating friction factors for spatially varied flow with increasing discharge.

Purpose The knowledge of the key genomic events that are causal to cancer development and progression not only is invaluable for our understanding of cancer biology but also may have a direct clinical impact. The task of deciphering a model of tumor progression by requiring that it explains (or at least does not contradict) known clinical and molecular evidence can be very demanding, particularly for cancers with complex patterns of clinical and molecular evidence. Materials and Methods We formalize the process of model inference and show how a progression model for neuroblastoma (NB) can be inferred from genomic data. The core idea of our method is to translate the model of clonal cancer evolution to mathematical testable rules of inheritance. Seventy-eight NB samples in stages 1, 4S, and 4 were analyzed with array-based comparative genomic hybridization. Results The pattern of recurrent genomic alterations in NB is strongly stage dependent and it is possible to identify traces of tumor progression in this type of data. Conclusion A tumor progression model for neuroblastoma is inferred, which is in agreement with clinical evidence, explains part of the heterogeneity of the clinical behavior observed for NB, and is compatible with existing empirical models of NB progression.

In order to identify moving loads on a bridge, the vehicle/bridge system is modeled as a simply supported beam subjected moving loads. The equation of motion of bridge is set up by finite element method. Based on the measured bridge responses, generalized orthogonal function approach and model superposition principle are used to obtain the derivatives of the modal responses, and the regularization technique is used to obtain the stable identified results. Simulation results and laboratory tests show that the method is effective and accurate to identify the moving loads on the bridge.

The slab-on-girder bridge is modeled as orthotropic plate, and the vehicles are modeled as a group of loads moving on top of the bridge deck at fixed distance and constant speed. The state equation of the system is obtained on the basis of theory of elastic plate, Halmiton's principle and the superposition principle. Based on the regularization technique a load identification method is developed in state space. Both the numerical simulation and laboratory tests show that the method is effective to identify the axle loads and the individual wheel loads by strains or displacements.

Over the past decade, there has been proliferation in the number of studies looking into IT enabled outsourcing. Little attention has been given to outsourcing of services in other sectors, such as Engineering and Facilities Management (EFM), which have also seen explosive growth. The article builds on a market research study of twenty-six outsourcing contracts making up approximately fifteen percent of Australia's EFM segment. This article aims to take a detailed look at the benefits sought and actually obtained from EFM outsourcing. The most successful contracts were then correlated against the most successful practitioners and the management issues further examined in five case studies. A number of learning points were apparent, and these can be grouped under four generic success factors: choice of contract style and management, relationship management, innovation management and workforce management. © 2005 Elsevier Ltd.

Organization-oriented analysis acts as the key step and foundation in building organization-oriented methodology (OOM) to engineer multi-agent systems especially open complex agent systems (OCAS). A number of existing approaches target OOM, while they are incompatible with each other, and none of them is available as a solid and practical tool for engineering OCAS. This paper summarizes our investigation in building a unified framework for abstracting and analyzing OCAS organizations. Our organizationoriented framework, referred to as ORGANISED, integrating and expanding existing approaches, explicitly captures the main attributes in an OCAS. Following this framework, individual modelbuilding blocks are developed for all ORGANISED members; both visual and formal specifications are utilized to present an intuitive and precise analysis . The above techniques have been deployed in developing an agent service-based trading and mining support infrastructure.

Open complex agent systems (OCAS) are middle-size or large-scale open agent organization. To engineer OCAS, agentcentric organization-oriented analysis, design and implementation, namely organization-oriented methodology (OOM), has emerged as a highly promising direction. A number of OOM-related approaches have been proposed; while there are some intrinsic issues hidden in them. For instance, some fundamental system attributes, such as system dynamics, are not covered by almost all of the existing approaches. In this paper, we summarize our investigation of existing approaches, and report a new OOM approach called OSOAD. The OSOAD approach consists of organizational abstraction (OA), organization-oriented analysis (OOA), agent service-oriented design (ASOD), and Java agent service -based implementation. OSOAD provides complete and deployable mechanisms for all software engineering phases. Specifically, we notice the transition supports from OA to OOA and ASOD. This approach has been built and deployed with the practical development of agent service -based financial trading and mining applications.

Its main findings are as follows: Turkey underutilises youth and women entrepreneurial resources; there exists a large informal economy that tends to support self-employment rather than entrepreneurship per se; entrepreneurs do not have the kinds of ties with organisations that might be helpful when they are first starting out; entrepreneurs see as their main problems bureaucracy and unstable state policies. Based on these findings, the paper concludes with a policy discussion regarding the development of entrepreneurship in Turkey.

The insights obtained from the collaborative model in this textile supply chain provide a good understanding of the benefits, bridges, and barriers associated with supply chain collaboration. Benefits can be grouped as customer‐oriented benefits, productivity benefits, and innovation related benefits. Factors supporting collaboration are observed as trust, common goals for cooperation, and existence of cooperation mechanisms, while barriers are related to three factors: lack of trust, risk‐benefit evaluation, and lack of common goals for cooperation.Research limitations/implicationsFindings are based on interviews and questionnaires conducted with the managers of 3T, 30 dyeing and finishing firms (ten are partners) and six technology‐supplying partner firms, from various regions in Turkey.Practical implicationsHighlights the importance of trust and collaboration mechanisms in managing collaborations.

In this paper we present a track matching algorithm based on the 'major color' histograms matching and the post-matching integration useful for tracking a single object across multiple, limitedly disjoint cameras. First, the Major Color Spectrum Histogram (MCSH) is introduced to represent a moving object in a single frame by its most frequent colors only. Then, a two-directional similarity measurement based on the MCHS is used to measure the similarity of any two given moving objects in single frames. Finally, our track matching algorithm extends the single-frame matching along the objects' tracks by a post-matching integration algorithm. Experimental results presented in this paper show the accuracy of the proposed track matching algorithm: the similarity of two tracks from the same moving objects has proved as high as 95%, while the similarity of two tracks from different moving objects has been kept as low as up to 28%. The post-matching integration step proves able to remove detailed errors occurring at the frame level, thus making track matching more robust and reliable. © Springer-Verlag Berlin Heidelberg 2005.

This paper presents a new algorithm for detection and compensation of backlight images. The proposed technique attacks the weakness of the conventional backlight image processing methods such as over-saturation, losing contrast and so on. The proposed algorithm consists of two operation phases: detection and compensation phases. In the detection phase, we use the spatial position characteristic and histogram of backlight image to obtain two image indices, which can determine the backlight degree of an image. Fuzzy logic is then used to integrate these two indices into a final backlight index determining the final backlight degree of an image precisely. Second, in the compensation phase, to solve the over-saturation problem that exists usually in conventional image compensation methods, we propose the adaptive compensation-curve scheme to compensate and enhance the brightness of backlight images. The luminance of a backlight image is adjusted according to the compensation curve, which is adapted dynamically according to the backlight degree indicated by the backlight index estimated in the detection phase. The performance of the proposed technique is tested on 100 backlight images covering various kinds of backlight conditions and degrees. The experimental and comparison results clearly show the superiority of the proposed technique.

The cellular neural network (CNN) is a powerful technique to mimic the local function of biological neural circuits for real-time image and video processing. Recently, it is widely accepted that using a set of CNNs in parallel can achieve higher-level information processing and reasoning functions either from application or biologics points of views. We introduce a novel framework for constructing a multiple-CNN integrated neural system called recurrent fuzzy CNN (RFCNN). This system can automatically learn its proper network structure and parameters simultaneously. In the RFCNN, each learned fuzzy rule corresponds to a CNN. Hence, each CNN takes care of a fuzzily separated problem region, and the functions of all CNNs are integrated through the fuzzy inference mechanism. Some on-line clustering algorithms are introduced for the structure learning, and the ordered-derivative calculus is applied to derive the recurrent learning rules of CNN templates in the parameter-learning phase. RFCNN provides a solution to the current dilemma on the decision of templates and/or fuzzy rules in the existing integrated (fuzzy) CNN systems. The capability of the RFCNN is demonstrated on the real-world vision-based defect inspection and image descreening problems proving that the RFCNN scheme is effective and promising. ©2005 IEEE.

Preventing accidents caused by drowsiness has become a major focus of active safety driving in recent years. It requires an optimal technique to continuously detect drivers' cognitive state related to abilities in perception, recognition, and vehicle control in (near-) real-time. The major challenges in developing such a system include: 1) the lack of significant index for detecting drowsiness and 2) complicated and pervasive noise interferences in a realistic and dynamic driving environment. In this paper, we develop a drowsiness-estimation system based on electroencephalogram (EEG) by combining independent component analysis (ICA), power-spectrum analysis, correlation evaluations, and linear regression model to estimate a driver's cognitive state when he/ she drives a car in a virtual reality (VR)-based dynamic simulator. The driving error is defined as deviations between the center of the vehicle and the center of the cruising lane in the lane-keeping driving task. Experimental results demonstrate the feasibility of quantitatively estimating drowsiness level using ICA-based multistream EEG spectra. The proposed ICA-based method applied to power spectrum of ICA components can successfully (1) remove most of EEG artifacts, (2) suggest an optimal montage to place EEG electrodes, and estimate the driver's drowsiness fluctuation indexed by the driving performance measure. Finally, we present a benchmark study in which the accuracy of ICA-component-based alertness estimates compares favorably to scalp-EEG based. © 2005 IEEE.

AbstractObjective: To determine the complications rate of termination of pregnancy (TOP) and the risk factors for complications following TOP. Methods: Retrospective observational study of the records of 1287 women who underwent TOP in the Department of Obstetrics and Gynaecology of the Postgraduate Institute of Medical Education and Research, Chandigarh, India, between 1997 and 2001. First‐trimester abortion was performed in 1088 women (85%) and second‐trimester abortion in 199 women (15%). Most women (76%) were aged between 26 and 30 years; they were educated and requested TOP primarily to limit the number of their children or to space their births. A malformed fetus was the indication for TOP in 5.9% cases, and 16% of the women had medical disorders associated with the pregnancy. Suction evacuation was the method of choice for first‐trimester abortion (88%); dinoprostone gel and extra‐amniotic saline solution plus oxytocin infusion were the primary methods (71%) for second‐trimester abortion. Results: Uterine perforation occurred in 1 patient (0.09%) after a first‐trimester abortion. The total rate of complications was 3.79% after first‐trimester and 4.0% after second‐trimester abortions. Excessive hemorrhage and retained placenta were chief complications associated with second‐trimester abortion. Incomplete abortion (1.5%) and minor infection were seen in 2.3% patients.

Conclusion: Termination of pregnancy is safe if adequate care is taken while performing the procedure.

ABSTRACTThis paper addresses the issue of services outsourcing by looking at both theoretical and empirical arguments. Previous debates have often concentrated on the motives for adopting the practice rather than the outcomes. These various themes can be discussed under the twin concepts of the cost and efficiency argument and the fashion and isomorphism approach. Our research provides strong evidence to support the cost efficiency argument. On average, significant cost advantages were sought and delivered, as well as improvements in service levels and systems. Many organisations in the current environment in Australia look at outsourcing not only as a method of increasing efficiency but also as gaining competitive advantage through harnessing the superior specialist skills and experience of the outsourcing provider who takes someone's back office function and transforms them into their front office. A 10% net cost saving was considered necessary by an organisation before embarking on an organisational change that was disruptive and in some cases involved downside risks. Even if other efficiency gains such as service levels or systems improvements were required, so were 10%+ cost savings. A number of the organisations thought their skills in managing outsourcing had improved considerably such that they were in a position to move from a client/server relationship to a partnership model (i.e. an alliance).

Objective: The mixed venous-arterial (v-a) pCO2 difference has been shown to be inversely correlated with the cardiac index (CI). A central venous pCO2, which is easier to obtain, may provide similar information. The purpose of this study was to examine the correlation between the central venous-arterial pCO2 difference and CI. Design: Prospective, cohort study. Setting: Intensive care unit of an urban tertiary care hospital. Patients and participants: Eighty-three consecutive intensive care unit patients. Measurements: Simultaneous blood gases from the arterial, pulmonary artery (PA), and central venous (CV) catheters were obtained. At the same time point, cardiac indices were measured by the thermodilution technique (an average of three measurements). The cardiac indices obtained by the venous-arterial differences were compared with those determined by thermodilution. Results: The correlation (R2) between the mixed venous-arterial pCO2 difference and cardiac index was 0.903 ( p <0.0001), and the correlation between the central venous-arterial pCO 2 difference and cardiac index was 0.892 ( p <0.0001). The regression equations for these relationships were natural log (CI)=1.837-0.159 (v-a) CO2 for the PA and natural log (CI)=1.787-0.151 (v-a) CO 2 for the CV ( p <0.0001 for both). The root-mean-squared error for the PA and CV regression equations were 0.095 and 0.101, respectively. Conclusion: Venous-arterial pCO2 differences obtained from both the PA and CV circulations inversely correlate with the cardiac index. Substitution of a central for a mixed venous-arterial pCO2 difference provides an accurate alternative method for calculation of cardiac output. © Springer-Verlag 2005.

The construction of two-qubit gates appropriate for universal quantumcomputation is of enormous importance to quantum information processing.Building such gates is dependent on accurate knowledge of the interactiondynamics between two qubit systems. This letter will present a systematicmethod for reconstructing the full two-qubit interaction Hamiltonian throughexperimental measures of concurrence. This not only gives a convenient methodfor constructing two qubit quantum gates, but can also be used toexperimentally determine various Hamiltonian parameters in physical systems. Weshow explicitly how this method can be employed to determine the first andsecond order spin-orbit corrections to the exchange coupling in quantum dots.

Efficient generation of spatially delocalised entangled states is at theheart of quantum information science. Generally flying qubits are proposed forlong range entangling interactions, however here we introduce a bus-mediatedalternative for this task. Our scheme permits efficient and flexible generationof deterministic two-qubit operator measurements and has links to the importantconcepts of mode-entanglement and repeat-until-success protocols. Importantly,unlike flying qubit protocols, our bus particle never contains informationabout the individual quantum states of the particles, hence isinformation-free.

In Australia, cost-benefit analysis (CBA) is one of the conventional tools used widely by the public and the private sectors in the appraisal of projects. It measures and compares the total costs and benefits of projects that are competing for scarce resources in monetary terms. Growing concerns that the values of environmental goods and services are often ignored or underestimated in the CBA approach have led to the overuse and depletion of environmental assets. A model of a sustainability index as an evaluation tool that combines economic, social and environmental criteria into an indexing algorithm is presented and described. The sustainability index uses monetary and non-monetary approaches to rank projects and facilities on their contribution to sustainability. This process enables the principle of trade-off to occur in the decision-making process and thereby allows environmental values to be considered when selecting a development option. This makes it possible to optimize financial return, maximize resource consumption and minimize detrimental effects to the natural and man-made world. A case study is used to demonstrate the model.

There is a growing concern about the negative effects that construction projects have on the natural environment. The values of environmental goods and services are often not included or are under-estimated in the traditional market-based approach which has led to the overuse and depletion of environmental assets. As such, a new or improved methodology needs to be developed in order that a comprehensive assessment of environmental matters can be incorporated in the evaluation process. A questionnaire survey was undertaken to detect the major environmental effects related to the construction industry and key components to be considered in the decision process were identified. This paper presents the development of a sustainability index for project appraisal. The methodology is based on a multi-criteria decision-making approach to combine the principal determinants of sustainable development into a single decision tool to appraise sustainable performance for built projects and facilities. This paper also presents results of applying the sustainability index in housing projects in New South Wales, Australia. Copyright © 2005 IAHS.

PurposeTo explore the collective means through which professional sports teams learn and generate new knowledge forms in order to remain competitive in challenging global arenas, and to examine the applicability of these means to business organizations.Design/methodology/approachThe objectives were achieved by drawing on the business and sporting experience of two executive coaches who have access to current elite‐level sports coaches. Through unstructured interviews with sports coaches and business executives over a period of years, the research question of collective learning in sports teams has been explored and its relevance to business contexts, analyzed.FindingsUsing social capital theory as an analytical lens, the research shows that organizational form is a critical determinant of the effectiveness of collective learning. This is the main reason why business teams are unable to emulate the successful learning that occurs in elite‐level sports teams. The research shows that the hierarchical structure of most business organizations constrains the development of the social capital necessary for sustained learning and knowledge construction.Practical implicationsThe primary implication of the research findings is that business leaders need to view their role as that of creating and managing a social environment in which mission‐pertinent learning and knowledge construction activities are nurtured. In practice, it means that the nature of business leadership and, in particular, power management practices in business organizations needs to be questioned and re‐conceptualized.Originality/valueUsing ...

PurposeThis paper describes and analyses an attempt to engage in transformational learning, oriented to the development of a culture of innovation, at a medium‐size software development organization in Australia.Design/methodology/approachAn action research methodology was used whereby continuous cycles of strategic social learning were collectively theorized, implemented, evaluated and renewed.FindingsThe most important finding of this study is that of the influence of power relations and communication practices upon learning‐for‐innovation in organizations, and the need for the mediation of this influence through the creation of an organizational role that we have entitled an “external critic”. The case also shows the central importance of the relational dimension of social capital generation to learning and the sensitivity of this dimension to power relations.Research limitations/implicationsThe research provides a rich analysis of one company's attempt to learn how to build and sustain a culture of innovation but, as with all case study research, the findings cannot be reliably generalized to other companies. Similarly, the case generates grounded theory that needs to be tested in other organizational contexts.Practical implicationsThe case raises the issue of power management in organizations and its relationship to social learning practices. In particular, it argues for the establishment of a “negotiated order” in organizations (through a mission, vision and core values that are collectively and meani...

<i>Background:</i> The influence of intravenous drug abuse (IVDA) on hemodialysis access placement practices and access survival in HIV-infected patients is unknown. <i>Methods:</i> We conducted a retrospective study of 60, HIV seropositive, maintenance hemodialysis patients. Type of access and assisted access survival (measured from date of placement) were compared in those with (77%) and without (23%) a history of IVDA. <i>Results:</i> Mean age was 37.8 years, mean baseline serum albumin was 2.9 g/dl and median CD4 count was 222 cells/mm<sup>3</sup>. Fifteen patients, all IVDA, were dialyzed using only tunneled catheters (median number of catheters per person (range): 2.5 (1–11)). There were longer delays in creation of a permanent access (p = 0.08), but no difference in the type of permanent access placed in IVDA versus the non-IVDA group. Over 1,051 cumulative months of access follow-up, 134 tunneled catheters, 28 grafts and 19 fistulae were placed, with observed failure rates of 1 per 4.7 access-months, 1 per 19.7 access-months, 1 per 38.2 access-months, respectively. The adjusted relative hazard of access failure for grafts versus catheters was 0.41 (95% CI: 0.23, 0.72; p = 0.002) and for fistulae versus catheters was 0.21 (95% CI: 0.08, 0.52; p = 0.001). Thirty-two percent of accesses were removed due to infection, an infection removal rate for catheters of 1 per 7.8 access-months and for grafts of 1 per 62.5 access-months; all graft infections occurred in the IVDA group. No fistula was removed due to infection. <i>Conclusion:</i> Fistulae are the first line of choice for hemodialysis access in HIV-seropositive patients regardless of IVDA history; if not feasible, graft placement in non-IVDA or abstinent IVDA patients is recommended. In those with active IVDA, the optimal method of renal replacement therapy and type of hemodialysis access remain uncertain.

Opioid receptor pharmacology in vivo has predicted a greater number of receptor subtypes than explained by the profiles of the three cloned opioid receptors, and the functional dependence of the receptors on each other shown in gene-deleted animal models remains unexplained. One mechanism for such findings is the generation of novel signaling complexes by receptor hetero- oligomerization, which we previously showed results in significantly different pharmacology for μ and δ receptor hetero-oligomers compared with the individual receptors. In the present study, we show that deltorphin-II is a fully functional agonist of the μ-δ heteromer, which induced desensitization and inhibited adenylyl cyclase through a pertussis toxin-insensitive G protein. Activation of the μ-δ receptor heteromer resulted in preferential activation of Gαz, illustrated by incorporation of GTPγ35S, whereas activation of the individually expressed μ and δ receptors preferentially activated Gαi. The unique pharmacology of the μ-δ heteromer was dependent on the reciprocal involvement of the distal carboxyl tails of both receptors, so that truncation of the distal μ receptor carboxyl tail modified the δ-selective ligand-binding pocket, and truncation of the δ receptor distal carboxyl tail modified the μ-selective binding pocket. The distal carboxyl tails of both receptors also had a significant role in receptor interaction, as evidenced by the reduced ability to co-immunoprecipitate when the carboxyl tails were truncated. The interaction between μ and δ receptors occurred constitutively when the receptors were co-expressed, but did not occur when receptor expression was temporally separated, indicating that the hetero-oligomers were generated by a co-translational mechanism. © 2005 by The American Society for Biochemistry and Molecular Biology, Inc.

In grazing cattle high fluoride (F) intakes are associated with soil ingestion. The ingestion of soil (F) (93% of dietary F) at a rate of 1562 mg F day–1 by mature dairy cows over 63 days, when compared with animals on basal diet (no soil) providing 110 mg F day–1, resulted in an increase in mean serum F concentrations from 0.10 to 0.22 mg litre–1, and no detectable change in mean metacarpal F concentrations (1125 mg F kg–1 DM), while the apparent absorption of soil F was 44%. However, an intake of soil F (77% of dietary F) at 446 mg F day–1 had no detectable effect on mean serum or bone F concentrations of the dairy cows. The relationship between soil F intake (x) and serum F concentration (y) was curvilinear (y = 0.0837e0.0007x). The observed changes in serum and bone concentrations indicate that the potential risk of fluorosis occurring in grazing dairy cows is very low. © 2005 Taylor & Francis Group, LLC.

This study aims at developing a simple and practical mathematical model to predict the performance of a submerged membrane adsorption hybrid system (SMAHS). Adsorption equilibrium and kinetic studies were first carried out with powdered activated carbon (PAC) for removing persisting organics from a synthetic wastewater. A series of short-term SMAHS experiments were conducted with preadsorption at different operating conditions such as aeration rate, backwash frequency, PAC dose and filtration flux. The Talu adsorption equilibrium and homogeneous surface diffusion model (HSDM) described well the isothermal adsorption behavior and adsorption kinetics, respectively. The semi-empirical mathematical model formulated for membrane-adsorption system predicts successfully the performance of SMAHS in terms of total organic carbon (TOC) removal. A coefficient known as 'membrane correlation coefficient (MCC)' introduced in the model was found to be very useful in describing both the adsorption of organics adsorbed onto the PAC and onto the membrane surface, and separation of PAC (with organics adsorbed on it) by the membrane. © 2004 Elsevier B.V.

This study aims at identifying the effect of pretreatment such as flocculation and/or adsorption on the performance of crossflow microfiltration (CFMF). CFMF performance was studied in terms of critical flux. The results indicated that: (1) flocculation alone as a pretreatment could effectively remove the large molecular weight organic matter from 30,000 to 60,000 Daltons; (2) flocculation, together with adsorption as a pretreatment to CFMF, could remove both large and small molecular weight organics; (3) flocculation as a pretreatment was significantly better than adsorption in improving the critical flux; (4) critical flux increased from 100 L/m2.h to 520 L/m2.h when flocculation-adsorption was applied. The critical flux in long-term experiments was the same as that of the short-term experiments. However, the critical flux slightly decreased (5%) in long-term experiments compared to short-term operation with flocculation and adsorption as a pretreatment. © 2005 Elsevier B.V.

Indeed, speech activated interface between human and autonomous/semi-autonomous systems requires accurate detection and recognition. In this area pitch and end-point detection is of vital importance. This paper presents a new method for pitch detection based on the continuous wavelet transform phase. The proposed technique can serve as an accurate pitch detector, and also can offer an efficient solution to the end-point detection problem. The extracted features from a user’s speech are then used to train a neural network for speech recognition. Experimental results are provided for the detection of pitch periods and end points and the recognition of a number of commands of male and female users. Laboratory tests are reported for the proposed voice control wheelchair system. © 2005 Inderscience Enterprises Ltd.

Low pasture magnesium (Mg) intakes by grazing dairy and beef cows is a main cause of hypomagnesaemia in these animals soon after calving. Magnesium fertiliser application to pasture can increase pasture mixed-herbage (hereafter “herbage") Mg concentration and reduce the risk of this disorder. However, the effectiveness of Mg fertilisers is variable depending on fertiliser type and soil properties. A 32-month Mg fertiliser field trial was conducted on dairy pasture on an Immature Orthic Pumice Soil (near Taupo, New Zealand; exchangeable Mg 0.4 cmolc kg–1, pasture Mg 0.13%) to compare the effectiveness of a range of Mg fertilisers in elevating herbage Mg concentration. The fertilisers used were ground serpentine rock, three acidulated serpentine rock products, Epsom salts, and E-mag (magnesium oxide). All fertilisers were applied at 100 kg Mg ha–1 at the start of the trial. The trial also had two treatments where Epsom salts was applied at 25 and 50 kg Mg ha–1 and a treatment where serpentine rock was reapplied during the second and third year at 100 kg Mg ha–1. Magnesium fertiliser treatments did not affect pasture dry matter yield significantly at any harvest, however, the effect of treatments on herbage Mg concentration was highly significant (P < 0.001) at all harvests. The single application of serpentine significantly increased herbage Mg concentration at 10 harvests, with five of these harvests having Mg concentrations ≥ 0.20%, which is generally considered to be the minimum “threshold level” for stock health. In comparison, the Mg concentration in pasture not receiving Mg fertiliser remained below the minimum threshold level throughout the trial. Application of serpentine rock annually further increased herbage Mg concentration and accumulation. The herbage Mg concentrations for this treatment were similar to those of the Epsom salts (50 kg Mg ha–1) treatment at the majority of the harvests. These results indicate that the annual application of serpentine r...

The escalating number of emergency department (ED) visits, length of stay, and hospital overcrowding have been associated with an increasing number of critically ill patients cared for in the ED. Existing physiologic scoring systems have traditionally been used for outcome prediction, clinical research, quality of care analysis, and benchmarking in the intensive care unit (ICU) environment. However, there is limited experience with scoring systems in the ED, while early and aggressive intervention in critically ill patients in the ED is becoming increasingly important. Development and implementation of physiologic scoring systems specific to this setting is potentially useful in the early recognition and prognostication of illness severity. A few existing ICU physiologic scoring systems have been applied in the ED, with some success. Other ED specific scoring systems have been developed for various applications: recognition of patients at risk for infection; prediction of mortality after critical care transport; prediction of in-hospital mortality after admission; assessment of prehospital therapeutic efficacy; screening for severe acute respiratory syndrome; and prediction of pediatric hospital admission. Further efforts at developing unique physiologic assessment methodologies for use in the ED will improve quality of patient care, aid in resource allocation, improve prognostic accuracy, and objectively measure the impact of early intervention in the ED. © 2005 BioMed Central Ltd.

Computers are now being increasingly used to support collaborative knowledge intensive processes. These are collaborative processes where intense interaction takes place between team members working towards a common goal. The paper identifies technology as an enabler of the collaborative work practices in such processes. To do this technology must provide ways to set up systems to support collaboration and at the same time assist users to adapt systems to changing work practices. The paper defines a collaborative metamodel to define collaborative work practices and to provide the ontology to define software agents that help users adapt it to changing needs. It then describes a prototype implementation.

Like nations and peoples, professions have histories too. Similar reasons for teaching history of nations and peoples may explain the importance of teaching prospective professionals the history of their profession. Indeed, much of K-16 education evolves around the teaching of history. Computing is not different with this respect. However, in the computing field, that often lacks attention to the societal impact of its products or an appreciation of the human side of the field, the inclusion of history of computing courses (or incorporating historical perspectives in computer science courses) is rare. In addition, the lack of formal education in computing history and the lack of relevant effective resources does not encourage faculty to incorporate history in their courses. Traditional historians often classify the history of computing as 'recent or contemporary history'. Indeed, the majority of undergraduate students currently an university and college programs were born after the personal computer and their teachers educated after the advent of email. Thus, though computers have strongly influenced their lives, they are generally unaware of the antecedents of the machines and tools they use every day. Hence, they usually do not build on the foundations of the field to explain a subject. Equally, myths and fallacies fill the field, including textbooks. The panel illustrates how teachers can integrate history of computing into traditional computer science education. Open discussion with the audience will follow the panelists' short presentations.

In the present study we investigate the effect of viscous dissipation on natural convection from a vertical plate placed in a thermally stratified environment. The reduced equations are integrated by employing the implicit finite difference scheme of Keller box method and obtained the effect of heat due to viscous dissipation on the local skin friction and local Nusselt number at various stratification levels, for fluids having Prandtl numbers of 10, 50, and 100. Solutions are also obtained using the perturbation technique for small values of viscous dissipation parameters and compared to the finite difference solutions for 0 1. Effect of viscous dissipation and temperature stratification are also shown on the velocity and temperature distributions in the boundary layer region. © 2005 Begell House, Inc.

The objective of this paper is to develop a multipurpose virtual-reality (VR) dynamic simulation system to meet the requirements of public security in the training of human operators. In this way, the operator can feel that he or she is controlling a real machine or vehicle to achieve the objective of real training. The developed VR dynamical simulation system in this paper mainly consists of three elements: a six-degree-of-freedom motion platform (Stewart platform), a force-reflection joystick, and an interactive VR scene. In the developed VR dynamic simulation system, the operator could sit on a Stewart platform to feel the velocity and orientation of motion, and could handle a force-reflection joystick to transfer the commands to the VR scene. Then, the operator will receive the force feedback from the Stewart platform and the joystick. Finally, a flight simulation scene is applied to illustrate the effectiveness of the developed VR dynamical simulation system. Experimental results demonstrate that the evaluation of the VR dynamical simulation system is comparatively good.

A new mutual information (MI)-based feature-selection method to solve the so-called large p and small n problem experienced in a microarray gene expression-based data is presented. First, a grid-based feature clustering algorithm is introduced to eliminate redundant features. A huge gene set is then greatly reduced in a very efficient way. As a result, the computational efficiency of the whole feature-selection process is substantially enhanced. Second, MI is directly estimated using quadratic MI together with Parzen window density estimators. This approach is able to deliver reliable results even when only a small pattern set is available. Also, a new MI-based criterion is proposed to avoid the highly redundant selection results in a systematic way. At last, attributed to the direct estimation of MI, the appropriate selected feature subsets can be reasonably determined. © 2005 IEEE.

The main purpose of this paper is to present analysis results for ISS that utilize dynamic programming techniques to characterize minimal ISS gains and transient bounds. These characterizations naturally lead to computable necessary and sufficient conditions for ISS. Our results make a connection between ISS and optimization problems in nonlinear dissipative systems theory (including L2-gain analysis and nonlinear H∞ theory). As such, the results presented address an obvious gap in the literature. © 2005 Elsevier Ltd. All rights reserved.

View description>>
Mg-based alloys, Mg1.9Cu0.1Niχ (χ = 1.8, 1.9, 2.0, 2.1), were fabricated through high-energy ball milling, and the effects of nickel content on the electrochemical characteristics have been investigated. A high discharge capacity of 490 mAhg-1 was observed for χ = 1.8, compared with 435 mAhg-1 for χ = 2.1. As to capacity degradation, 66.7 % of initial capacity was lost after 15 cycles for χ = 1.8, while only 47.2% for χ = 2.1. Cyclic Voltammograms (CV) indicates that nickel can help maintain redox reaction current and consequently improve the cycle performance. The X-ray mapping analysis indicates that Mg, Ni, and Cu are uniformly distributed in the particles. The O content in the alloy electrodes after 15 cycles decreases with the increase of Ni content in the alloys, suggesting that Ni can efficiently suppress the formation of Mg(OH) 2. The linear polarization curves show that the exchange current density, namely the rate of hydriding/dehydriding, increases from 13 mAg -1 to 133 mAg-1 when the nickel content varies from 1.8 to 2.1. This is also considered as a reason for the observed improved capacity stability. © J. New. Mat. Electrochem. Systems.

A document fragmentation policy was presented by taking advantage of document object model (DOM) for XML, and a corresponding fragmentation algorithm was designed according to the element fan-outs, to solve the problem of document fragmentation for XML streams based on Hole-Filler model. A tag-based document fragmentation algorithm built on DOM-based algorithm was then proposed to determine document filler points by fragmenting tag structure, so as to reduce the comparisons between element fan-outs and threshold. Finally, an optimized fragmentation policy was presented to avoid trivial pieces by binding XML sub-trees according to the ratio of element fan-outs and threshold. Our performance study shows that the document fragmentation algorithms perform well on execution time, granularity and other metrics.

RNAi is a conserved gene‐specific regulatory mechanism, which silences target gene expression transcriptionally and post‐transcriptionally. The RNAi machinery converts the sequence specific information of a long double stranded RNAs (dsRNAs) into small 21–22 nt long dsRNAs (siRNAs, miRNAs) which assemble into an effector complex, the RNA induced silencing complex (RISC). RISC assembly is asymmetric; one strand of an siRNA or a miRNA preferentially incorporates into the RNA–protein complex. Here, I review the rules of the asymmetric RISC formation and discuss their possible regulatory function in several steps in RNAi.

Influence of corrugation of limited extent on the performance of fixed-incline slider bearings of infinite width is investigated numerically. Effects of the corrugated section’s parameters like its location, length, and corrugation amplitude, on pressure distribution in the bearing’s fluid film, its load supporting capacity W and flow rate, are considered. When this section is near the entrance to the bearing gap, pressure and W are reduced in comparison with the smooth wall case. As this section is located further downstream, peak pressure and W increase, whereas flow rate decreases. These effects are reinforced by longer corrugated section and larger corrugation amplitude. The results thus point to a simple way to substantially enhance a bearing’s load-supporting capacity.

A commonly used flood mitigation technique in coastal areas of Australia during the late 1960s was the installation of one-way floodgates on flood mitigation drains. In regions affected by acid sulphate soils (the oxidation of pyrite in the soil forms sulphuric acid), the floodgates prevent tidal carbonate/bicarbonate buffering of the drains and thereby create reservoirs of acidic water (pH < 4.5) that discharge during low tide. Several acid sulphate soil remediation techniques have been used in coastal lowland in southeastern NSW, Australia. Following extensive monitoring and finite element modelling of groundwater conditions and quality, fixed level V-notch weirs were installed at three elevations to maintain elevated groundwater levels. The weirs successfully maintained the groundwater level above the acid sulphate soils, preventing additional pyrite oxidation, and reduced the rate of discharge of acid to the drain. Following further monitoring, investigation into anaerobic acid sources, and finite element-based geochemical modelling, modified two-way floodgates that allow tidal ingress were installed. The modified floodgates were successful in buffering the drain water pH before discharging the drain water into adjacent waterways. Numerical analysis based on finite element modelling was extended to illustrate that saline intrusion into the surrounding soil (as a result of tidal ingress and acid buffering in the drains) was not a major concern for the pastureland or other agricultural activities.

A system of vertical drains combined with vacuum preloading is an effective method to accelerate soil consolidation by promoting radial flow. This study presents the analytical modeling of vertical drains incorporating vacuum preloading in both axisymmetric and plane strain conditions. The effectiveness of the applied vacuum pressure along the drain length is considered. The exact solutions applied on the basis of the unit cell theory are supported by finite element analysis using ABAQUS software. Subsequently, the details of an appropriate matching procedure by transforming permeability and vacuum pressure between axisymmetric and equivalent plane strain conditions are described through analytical and numerical schemes. The effects of the magnitude and distribution of vacuum pressure on soft clay consolidation are examined through average excess pore pressure, consolidation settlement, and time analyses. Lastly, the practical implications of this study are discussed.Key words: consolidation, finite element method, soft clay, vacuum preloading, vertical drains.

A system of vertical drains, with surcharge load to accelerate consolidation by shortening the drainage path, is one of the most popular methods of soft ground improvement. The conventional radial consolidation theory (including smear and well resistance) has been commonly used to predict the behaviour of vertical drains in soft clay. Its mathematical formulation is based on the small strain theory; and for a given stress range, a constant volume compressibility (mv) and a constant coefficient of horizontal permeability (kh) are assumed. However, the value of mvvaries along the consolidation curve over a wide range of applied pressure (Δp). In the same manner, khalso changes with the void ratio (e). In this paper, the writers have replaced mvwith the compressibility indices (Ccand Cr), which define the slopes of the e log σ′ relationship. Moreover, the variation of the horizontal permeability coefficient (kh) with the void ratio (e) during consolidation is represented by the e log khrelationship that has a slope of Ck. In contrast to the conventional analysis, the current study highlights the influence of the Cc/Ck(or Cr/Ck) ratio and the preloading increment ratio (Δp/σi) on the consolidation process. The analytical predictions are compared with the experimental results when a large-scale consolidation chamber was used, and these predictions show good agreement with the measured data. Finally, an embankment case history taken from Muar Plains, Malaysia, is analysed on the basis of the current solution and compared with field measurements.Key words: compressibility, embankments, permeability, soft soils, soil consolidation, vertical...

This chapter starts with an introduction of a revised analytical model of radial drainage with vacuum preloading in both axisymmetric and plane strain conditions. Observed from large-scale radial drainage consolidation tests, the influence of vacuum pressure distribution along the drain length is examined through the dissipation of average excess pore pressure and associated settlement. The details of an appropriate conversion procedure by transforming permeability and vacuum pressure between axisymmetric and equivalent plane strain conditions are described through analytical and numerical schemes. The effects of the magnitude and distribution of vacuum pressure on soft clay consolidation are investigated on the basis of average excess pore pressure consolidation settlement, and time analyses. The writers describe a multi-drain plane strain finite element method analysis based on permeability conversion, which is employed to study the behavior of embankments stabilized at the site of the Second Bangkok International Airport with vacuum-assisted prefabricated vertical drains. In the field, a constant suction head is not always stable because of the occurrence of air leaks; therefore the magnitude of applied vacuum pressure was adjusted accordingly. The theoretical (numerical) predictions are compared with measured field data such as settlements, excess pore pressures, and lateral movements. The case history analysis employing the writers' model indicates improved accuracy of the predictions in relation to the field observations. The data indicate that the efficiency of the prefabricated vertical drains depends on the magnitude and distribution of vacuum pressure as well as on the extent of air leak protection provided in practice. © 2005 Elsevier Ltd.

This paper describes the analytical formulation of a modified consolidation theory incorporating vacuum pressure, and numerical modeling of soft clay stabilized by prefabricated vertical drains, with a linearly distributed (trapezoidal) vacuum pressure for both axisymmetric and plane strain conditions. The effects of the magnitude and distribution of vacuum pressure on soft clay consolidation are examined through average time-dependent excess pore pressure and consolidation settlement analyses. The plane strain analysis was executed by transforming the actual vertical drains into a system of equivalent parallel drain walls by adjusting the coefficient of permeability of the soil and the applied vacuum pressure. The converted parameters are incorporated in the finite element code ABAQUS, employing the modified Cam-clay theory. Numerical analysis conducted to study the performance of a full-scale test embankment constructed on soft Bangkok clay. The performance of this selected embankment is predicted on the basis of four different vacuum pressure distributions. The predictions are compared with the available field data. The assumption of distributing the vacuum pressure as a constant over the soil surface and varying it linearly along the drains seems justified in relation to the field data. © ASCE.

Infill materials found in natural rock joints may cause a reduction in joint shear strength, influencing rock mass stability. This paper reports a study aimed at developing a semi-empirical methodology for predicting the shear strength of infilled joints, taking into account joint surface characteristics and the properties of the joint and infill materials. A new model for predicting the shear strength of infilled joints is presented, on the basis of a series of tests carried out on two types of model joint surface having asperity angles of 9·5° and 18·5°, with graphite and bentonite used as infill materials. All tests were carried out in a large-scale shear apparatus under constant normal stiffness (CNS) conditions. The results indicate that at low infill thickness to asperity height ratio (t/a), the combined effect of the basic friction angle (ϕb) and the joint asperity angle (i) is pronounced, but it diminishes with increasing t/a ratio so that the shear strength converges towards that of the infill alone. Summation of two algebraic functions (A and B) that represent the joint and infill characteristics correctly models the decay of normalised shear strength with increasing t/a ratio. The new model successfully describes the observed shear strengths of the graphite and clay (bentonite) filled model joints.

The region is solated from overseas markets, main shipping and air routes and from other Pacific Nations. Five of the South Pacific nation states are classified as 'least developed', including the Solomon Islands. Economically, government and civil instituotions are spread thin over large areas on the islands, and what human resources do exist are largely undeveloped, hindering economic development. External pressures for structural reform, individual land titling, and privatisation extend from neighbouring economic powers Australia and New Zealand. Much foreign assistance to date has focused on top-down solutions for a problem that really needs rural based sustainable development; recent programmes of rural-oriented assistance have been challenged by logistics, transaction costs and the mismatch of objectives across cultural divides.

Numerous mathematical models have been developed to evaluate both initial and transient stage removal efficiency of deep bed filters. Microscopic models either using trajectory analysis or convective-diffusion equations were used to compute the initial removal efficiency. These models predicted the removal efficiency under favorable filtration conditions quantitatively, but failed to predict the removal efficiency under unfavorable conditions. They underestimated the removal efficiency under unfavorable conditions. Thus, semi-empirical formulations were developed to compute initial removal efficiencies under unfavorable conditions. Also, correction for the adhesion of particles onto filter grains improved the results obtained for removal efficiency from the trajectory analysis. Macroscopic models were used to predict the transient stage removal efficiency of deep bed filters. The O'Melia and Ali(1) model assumed that the particle removal is due to filter grains as well as the particles that are already deposited onto the filter grain. Thus, semi-empirical models were used to predict the ripening of filtration. Several modifications were made to the model developed by O'Melia and Ali to predict the deterioration of particle removal during the transient stages of filtration.

The trivial equilibrium of a nonlinear autonomous system with time delay may become unstable via a Hopf bifurcation of multiplicity two, as the time delay reaches a critical value. This loss of stability of the equilibrium is associated with two coincident pairs of complex conjugate eigenvalues crossing the imaginary axis. The resultant dynamic behaviour of the corresponding nonlinear non-autonomous system in the neighbourhood of the Hopf bifurcation is investigated based on the reduction of the infinite-dimensional problem to a four-dimensional centre manifold. As a result of the interaction between the Hopf bifurcating periodic solutions and the external periodic excitation, a primary resonance can occur in the forced response of the system when the forcing frequency is close to the Hopf bifurcating periodic frequency. The method of multiple scales is used to obtain four first-order ordinary differential equations that determine the amplitudes and phases of the phase-locked periodic solutions. The first-order approximations of the periodic solutions are found to be in excellent agreement with those obtained by direct numerical integration of the delay-differential equation. It is also found that the steady state solutions of the nonlinear non-autonomous system may lose their stability via either a pitchfork or Hopf bifurcation. It is shown that the primary resonance response may exhibit symmetric and asymmetric phase-locked periodic motions, quasi-periodic motions, chaotic motions, and coexistence of two stable motions. © 2005 Elsevier Ltd.

This paper is concerned with a study of the influence of a time delay occurring in a PD feedback control on the dynamic stability of a rotor suspended by magnetic bearings. In the presence of geometric coordinate coupling and time delay, the equations of motion governing the response of the rotor are a set of two-degree-of-freedom nonlinear differential equations with time delay coupling in nonlinear terms. It is found that as the time delay increases beyond a critical value, the equilibrium position of the rotor motion becomes unstable and may bifurcate into two qualitatively different kinds of periodic motion. The resultant Hopf bifurcation is associated with two coincident pairs of complex conjugate eigenvalues crossing the imaginary axis. Based on the reduction of the infinite dimensional problem to the flow on a four-dimensional center manifold, the bifurcating periodic solutions are investigated using a perturbation method.

The trivial equilibrium of a two-degree-of-freedom autonomous system may become unstable via a Hopf bifurcation of multiplicity two and give rise to oscillatory bifurcating solutions, due to presence of a time delay in the linear and nonlinear terms. The effect of external excitations on the dynamic behaviour of the corresponding non-autonomous system, after the Hopf bifurcation, is investigated based on the behaviour of solutions to the four-dimensional system of ordinary differential equations. The interaction between the Hopf bifurcating solutions and the high level excitations may induce a non-resonant or secondary resonance response, depending on the ratio of the frequency of bifurcating periodic motion to the frequency of external excitation. The first-order approximate periodic solutions for the non-resonant and super-harmonic resonance response are found to be in good agreement with those obtained by direct numerical integration of the delay differential equation. It is found that the non-resonant response may be either periodic or quasi-periodic. It is shown that the super-harmonic resonance response may exhibit periodic and quasi-periodic motions as well as a co-existence of two or three stable motions. © Springer 2005.

This study demonstrates that both synthetic and natural endocrine disrupting chemicals (EDCs) (e.g., bisphenol A, estrone and 17β-estradiol) were found in the crude wastewaters from two wastewater treatment works (WwTWs). Conventional biological processes can lower EDCs concentrations to several tens to hundreds ng l-1. Since natural EDCs (e.g., estrone and 17β-estradiol) have biological activity and adverse impact on the environment at extremely low concentrations (several tens of ng l-1), further treatment after conventional biological processes is required. Preliminary trials with ferrate(VI) and electrochemical oxidation process demonstrated that both processes can effectively reduce EDCs to very low levels, ranging between 10 and 100 ng l-1, but the former is more effective than the latter to reduce COD concentration in wastewater for given studying conditions. © 2005 Elsevier Ltd.

This paper presents the experimental results carried out to evaluate CO, HC and NOx exhaust emissions and performance characteristics of a computer integrated bi-fuel spark ignition engine that has been retrofitted for two fuels namely, gasoline and compressed natural gas (CNG). The ignition point was optimised for CNG through the external device so that the maximum cylinder pressure occurred at similar as gasoline fuel such as between 10 to 10.50 deg crank angles after top dead centre (TDC). The used engine is a 4-cylinder spark ignition engine that has been operated with steady state condition using engine operating software and data acquisition system called CADET6. An eddy current dynamometer was used to measure engine performance characteristics such as engine brake power and fuel consumption and to give load on engine during measuring emission characteristics. Bosch and Bacharach exhaust gas analysers were used to measure emissions gases such as CO, HC and NOx. The performance test was done with full throttle condition and corresponding air-fuel (AFR) was evaluated. The emissions test was done with fixed load condition for both the fuels. The results show that CNG reduces 15% brake power with 15% to 18% reduction in specific fuel consumption (SFC) as compared to gasoline fuel. This is mainly due to the gases nature of CNG fuel. The emissions results show that CNG reduces CO and HC emissions but increases NOx emissions. The details about the emissions and performance results with three way catalytic (TWC) converter have been presented and discussed. The results of this experiment will be used to develop of new dedicated natural gas engines. © 2005 Taylor & Francis Group, LLC.

Abstract Purpose: The INK4A-ARF locus at chromosome 9p21 is frequently altered in head and neck squamous cell carcinoma (SCC) and encodes two distinct tumor suppressors, p16INK4A and p14ARF. This study addressed the role of p14ARF as a potential prognostic marker in this disease. Experimental Design: p14ARF protein expression was assessed by immunohistochemistry in a cohort of 140 patients with SCC of the anterior tongue. Using univariate and multivariate Cox's proportional hazards models, the outcomes examined were time to disease recurrence or death, with or without clinicopathologic covariates, including nodal status, disease stage, treatment status, Ki-67 staining, and molecular markers with known functional or genetic relationships with p14ARF (p16INK4A, p53, pRb, p21WAF1/CIP1, E2F-1). Results: On multivariate analysis, p14ARF positivity (nucleolar p14ARF staining and/or nuclear p14ARF staining in ≥30% of tumor cells) was an independent predictor of improved disease-free survival (DFS; P = 0.002) and overall survival (OS; P = 0.002). This was further enhanced when p14ARF positivity was cosegregated with positive (≥1%) p16INK4A staining (DFS, P < 0.001; OS, P < 0.001). Patients whose cancers were p14ARF negative and p53 positive (>50%) had the poorest outcome (DFS, P < 0.001; OS, P < 0.001) of any patient subgroup analyzed. Conclusions: These data show that in patients with SCC of the tongue, combined nuclear and nucleolar expression of p14ARF protein predicts for improved DFS and OS independent of established prognostic markers.

The apelin peptide is the endogenous ligand for the apelin G protein-coupled receptor. The distribution of the apelin peptides and receptor are widespread in the central nervous system and periphery, with reported roles in the hypothalamic-pituitary-adrenal axis, blood pressure regulation and as one of the most potent positive inotropic substances yet identified. In this report, we show that in native tissues preproapelin exists as a dimer. Dimeric preproapelin was reduced to monomers by dithiothreitol treatment, indicating disulfide linkages. To evaluate the role of the carboxyl-terminal phenylalanine in the hypotensive action of apelin-13, analogs were generated and tested for their role on blood pressure regulation. Injections of apelin-13 and apelin-12 (15 μg/kg) into spontaneously hypertensive rats lowered systolic and diastolic blood pressure to result in decreases of approximately 60% and 15% in mean arterial blood pressure, respectively. Apelin-13(13[d-Phe]) treatment did not differ from apelin-13 in either efficacy or duration of effect, whereas apelin-13(F13A) revealed a loss of function. However, concomitant administration of apelin-13(F13A) (30 μg/kg) blocked hypotensive effects of apelin-13 (15 μg/kg), which revealed that apelin-13(F13A) behaved as an apelin-specific antagonist.

Abstract Motivation: Discovery of binding sites is important in the study of protein–protein interactions. In this paper, we introduce stable and significant motif pairs to model protein-binding sites. The stability is the pattern’s resistance to some transformation. The significance is the unexpected frequency of occurrence of the pattern in a sequence dataset comprising known interacting protein pairs. Discovery of stable motif pairs is an iterative process, undergoing a chain of changing but converging patterns. Determining the starting point for such a chain is an interesting problem. We use a protein complex dataset extracted from the Protein Data Bank to help in identifying those starting points, so that the computational complexity of the problem is much released. Results: We found 913 stable motif pairs, of which 765 are significant. We evaluated these motif pairs using comprehensive comparison results against random patterns. Wet-experimentally discovered motifs reported in the literature were also used to confirm the effectiveness of our method.

The binding in protein-protein interactions exhibits a kind of biochemical stability in cells. The mathematical notion of fixed points also describes stability. A point is a fixed point if it remains unchanged after a transformation by a function. Many points may not be a fixed point, but they may approach a stable status after multiple steps of transformation. In this paper, we define a point as a protein motif pair consisting of two traditional protein motifs. We propose a function and propose a method to discover stable motif pairs of this function from a large protein interaction sequence data set. There are many interesting properties for this function (for example, the convergence). Some of them are useful for gaining much efficiency in the discovery of those stable motif pairs; some are useful for explaining why our proposed fixed point theorems are a good way to model the binding of protein interactions. Our results are also compared to biological results to elaborate the effectiveness of our method. © 2005 IEEE.

In this paper we discuss dynamic model reduction methods which preserve a certain structure in the underlying system. Specifically, we consider the situation where the reduction must be consistent with a partition of the system states. This is motivated, for instance, in situations where state variables are associated with the topology of a networked system, and the reduction should preserve this. We build on the observation that imposing block structure to generalized controllability and observability gramians automatically yields such state-partitioned model reduction. The difficulty lies in ensuring feasibility of the resulting Lyapunov inequalities, which is in general very restrictive. To overcome this, we consider coprime factor model reduction. We derive an LMI characterization of expansive and contractive coprime factorizations that preserve structure, and use this to build a more flexible method for structured model reduction. An example is given to illustrate the method. © 2004 Elsevier Ltd. All rights reserved.

Differentiated Service (DiffServ) architecture has been proposed as a scalable QoS architecture for Internet. DiffServ, however, could not control its loads under heavy traffic conditions, and it could not provide strong QoS responses for individual traffic flow. This paper introduces at the edges of a DiffServ domain, a novel two-level admission control scheme, the Fair Intelligent Admission Control (FIAC). At per-class level, FIAC admits traffic according their fairshare and usage while preventing possible congestion within the DiffServ core. At per-flow level, FIAC estimates and allocates the fairshare for each flow within a class. Simulation results demonstrate that FIAC adheres extremely well to the bandwidth requirements of DiffServ classes while preventing congestion within the DiffServ core. With FIAC's per-flow level enabled, FIAC is able to prevent uncontrolled UDP flows from depriving TCP-controlled flows of bandwidth share when they are aggregated to the DiffServ domain.

In this paper, a recurrent compensatory neuro-fuzzy system (RCNFS) for identification and prediction is proposed. The compensatory-based fuzzy method uses the adaptive fuzzy operations of neuro-fuzzy systems to make fuzzy logic systems more adaptive and effective. A recurrent network is embedded in the RCNFS by adding feedback connections in the second layer, where the feedback units act as memory elements. In this paper, the RCNFS model is proved to be a universal approximator. Also, an online learning algorithm is proposed which can automatically construct the RCNFS. There are no rules initially in the RCNFS. They are created and adapted as online learning proceeds through simultaneous structure and parameter learning. Structure learning is based on the degree measure and parameter learning is based on the ordered derivative algorithm. Finally, the RCNFS is used in several simulations. The simulation results of the dynamic system model have shown that (1) the RCNFS model converges quickly; (2) the RCNFS model requires a small number of tuning parameters; (3) the RCNFS model can solve temporal problems and approximate a dynamic system. © 2004 Elsevier B.V.

In this paper, we propose a new pedestrian detection algorithm, and use it to develop a real-time pedestrian detection system. The pedestrian detection algorithm can be functionally partitioned into two parts: moving object segmentation and pedestrian recognition. In moving object segmentation, we segment the moving objects in the scene by modified temporal differencing method. This method combines general temporal differencing method with detection nets. In pedestrian recognition, we obtain multi-type wavelet templates from input images. Interest points are extracted from wavelet templates. Then, feature points are extracted by statistical method from interest point templates. Finally, these feature points are fed into a trained multilayer back-propagation neural network. The output of the neural network implies the result - pedestrian or non-pedestrian. From experiments, accuracy rate of recognition achieves 95%. We implement this algorithm in a real-time pedestrian detection system. The system can detect pedestrians in the scene in real time. The pedestrian detection rate is 92.58%. © 2005 TFSA.

Over one-third of protein structures contain metal ions, which are the necessary elements in life systems. Traditionally, structural biologists were used to investigate properties of metalloproteins (proteins which bind with metal ions) by physical means and interpreting the function formation and reaction mechanism of enzyme by their structures and observations from experiments in vitro. Most of proteins have primary structures (amino acid sequence information) only; however, the 3-dimension structures are not always available. In this paper, a direct analysis method is proposed to predict the protein metal-binding amino acid residues from its sequence information only by neural networks with sliding window-based feature extraction and biological feature encoding techniques. In four major bulk elements (Calcium, Potassium, Magnesium, and Sodium), the metal-binding residues are identified by the proposed method with higher than 90% sensitivity and very good accuracy under 5-fold cross validation. With such promising results, it can be extended and used as a powerful methodology for metal-binding characterization from rapidly increasing protein sequences in the future.

The accurate classification of protein structure is critical and essential for protein function determination in Bioinformatics and Proteomics. A reasonably high rate of prediction accuracy for protein structure classification has been achieved recently in coarse-grained protein class assignment according to their primary amino acid sequences, such as classifying proteins into four classes in SCOP. However, it is still quite a challenge for fine-grained protein fold assignment, especially when the number of possible folding patterns as those defined in SCOP is large. In our previous work, hierarchical learning architecture (HLA) neural networks have been used to differentiate proteins according to their classes and folding patterns. A better prediction accuracy rate for 27 folding categories was 65.5% which improves previous results by Ding and Dubchak with 56.5% prediction accuracy rate. The success of the protein structure classification depends heavily on the computational methods used and the features selected. Here combinatorial fusion analysis (CFA) techniques are used to facilitate feature selection and combination for improving prediction accuracy rate of protein structure classification. The resulting classification has an overall prediction accuracy rate of 87.8% for coarse-grained 4 classes and 70.9% for fine-grained 27 folding categories by applying the concept of CFA to our previous work using neural network with the HLA framework. These results are significantly higher than others and our previous work. They further demonstrate that the CFA techniques can greatly enhance the machine learning method (such as NN in the paper) in the protein structure prediction problem.

This paper presents a fuzzy-tuned neural network, which is trained by an improved genetic algorithm (GA). The fuzzy-tuned neural network consists of a neural-fuzzy network and a modified neural network. In the modified neural network, a neuron model with two activation functions is used so that the degree of freedom of the network function can be increased. The neural-fuzzy network governs some of the parameters of the neuron model. It will be shown that the performance of the proposed fuzzy-tuned neural network is better than that of the traditional neural network with a similar number of parameters. An improved GA is proposed to train the parameters of the proposed network. Sets of improved genetic operations are presented. The performance of the improved GA will be shown to be better than that of the traditional GA. Some application examples are given to illustrate the merits of the proposed neural network and the improved GA. © World Scientific Publishing Company.

The paper presents an electric load balancing system for domestic use. An electric load forecasting system, which is realized by a genetic algorithm-based modified neural network, is employed. On forecasting the home power consumption profile, the load balancing system can adjust the amount of energy stored in battery accordingly, preventing it from reaching certain practical limits. A steady consumption from the AC mains can then be obtained which will benefit both the users and the utility company. An example will be given to illustrate the merits of the forecaster, and its performance on achieving the load balancing.

The extensive amount of multimedia information available necessitates content-based video indexing and retrieval methods. Since humans tend to use high-level semantic concepts when querying and browsing multimedia databases, there is an increasing need for semantic video indexing and analysis. For this purpose, we present a unified framework for semantic shot classification in sports video, which has been widely studied due to tremendous commercial potentials. Unlike most existing approaches, which focus on clustering by aggregating shots or key-frames with similar low-level features, the proposed scheme employs supervised learning to perform a top-down video shot classification. Moreover, the supervised learning procedure is constructed on the basis of effective mid-level representations instead of exhaustive low-level features. This framework consists of three main steps: 1) identify video shot classes for each sport; 2) develop a common set of motion, color, shot length-related mid-level representations; and 3) supervised learning of the given sports video shots. It is observed that for each sport we can predefine a small number of semantic shot classes, about 5-10, which covers 90%-95% of broadcast sports video. We employ nonparametric feature space analysis to map low-level features to mid-level semantic video shot attributes such as dominant object (a player) motion, camera motion patterns, and court shape, etc. Based on the fusion of those mid-level shot attributes, we classify video shots into the predefined shot classes, each of which has clear semantic meanings. With this framework we have achieved good classification accuracy of 85%-95% on the game videos of five typical ball type sports (i.e., tennis, basketball, Volleyball, soccer, and table tennis) with over 5500 shots of about 8 h. With correctly classified sports video shots, further structural and temporal analysis, such as event detection, highlight extraction, video skimming, and table of conte...

In ad hoc networks there is a need for all-to-one protocols that allow for information collection or 'sensing' of the state of an ad hoc network and the nodes that comprise it. Such protocols may be used for service discovery, auto-configuration, network management, topology discovery or reliable flooding. There is a parallel between this type of sensing in ad hoc networks and that of sensor networks. However, ad hoc networks and sensor networks differ in their application, construction, characteristics and constraints. The main priority of sensor networks is for the flow of data from sensors back to a sink, but in an ad hoc network this may be of secondary importance. Hence, protocols suitable to sensor networks are not necessarily suitable to ad hoc networks and vice versa. We propose, Resource Aware Information Collection (RAIC), a distributed two phased resource aware approach to information collection in ad hoc networks. RAIC utilises a resource aware optimised flooding mechanism to both disseminate requests and initialise a backbone of resource suitable nodes responsible for relaying replies back to the node collecting information. RAIC in the process of collecting information from all nodes in an ad hoc network is shown to consume less energy and introduce less overhead compared with Directed Diffusion and a brute force approach. Importantly, over multiple successive queries (in an energy constrained environment), the use of resource awareness allows for the load of relaying to be distributed to those nodes most suitable, thereby extending the lifetime of the network. © 2004 Elsevier B.V.

AbstractWe consider estimation of various probabilities after termination of a group sequential phase II trial. A motivating example is that the stopping rule of a phase II oncologic trial is determined solely based on response to a drug treatment, and at the end of the trial estimating the rate of toxicity and response is desirable. The conventional maximum likelihood estimator (sample proportion) of a probability is shown to be biased, and two alternative estimators are proposed to correct for bias, a bias‐reduced estimator obtained by using Whitehead's bias‐adjusted approach, and an unbiased estimator from the Rao–Blackwell method of conditioning. All three estimation procedures are shown to have certain invariance property in bias. Moreover, estimators of a probability and their bias and precision can be evaluated through the observed response rate and the stage at which the trial stops, thus avoiding extensive computation.

Abstract Summary: DNAFSMiner (DNA Functional Sites Miner) is a web-based software toolbox to recognize functional sites in nucleic acid sequences. Currently in this toolbox, we provide two software: TIS Miner and Poly(A) Signal Miner. The TIS Miner can be used to predict translation initiation sites in vertebrate DNA/mRNA/cDNA sequences, and the Poly(A) Signal Miner can be used to predict polyadenylation [poly(A)] signals in human DNA sequences. The prediction results are better than those by literature methods on two benchmark applications. This good performance is mainly attributable to our unique learning method. DNAFSMiner is available free of charge for academic and non-profit organizations. Availability: http://research.i2r.a-star.edu.sg/DNAFSMiner/ Contact: huiqing@i2r.a-star.edu.sg

Motivation: Patient outcome prediction using microarray technologies is an important application in bioinformatics. Based on patients' genotypic microarray data, predictions are made to estimate patients' survival time and their risk of tumor metastasis or recurrence. So, accurate prediction can potentially help to provide better treatment for patients. Results: We present a new computational method for patient outcome prediction. In the training phase of this method, we make use of two types of extreme patient samples: short-term survivors who got an unfavorable outcome within a short period and long-term survivors who were maintaining a favorable outcome after a long follow-up time. These extreme training samples yield a clear platform for us to identify relevant genes whose expression is closely related to the outcome. The selected extreme samples and the relevant genes are then integrated by a support vector machine to build a prediction model, by which each validation sample is assigned a risk score that falls into one of the special pre-defined risk groups. We apply this method to several public datasets. In most cases, patients in high and low risk groups stratified by our method have clearly distinguishable outcome status as seen in their Kaplan-Meier curves. We also show that the idea of selecting only extreme patient samples for training is effective for improving the prediction accuracy when different gene selection methods are used. © The Author 2005.

A study was conducted to determine the effect of ectomycorrhizal hyphae on phosphate rock dissolution and soil properties in the rhizosphere of one-year-old Pinus radiata D. Don seedlings established on an allophanic soil (Andosol) in the field. High and low ectomycorrhizal hyphal activities were produced in soils inside the lower compartments of rhizosphere study containers by using either 26 μm or <10 μm pore-size nylon mesh(es) at the interfaces between the lower and upper compartments. The meshes at the interfaces allowed (26 μm) or reduced (<10 μm) hyphae penetration into the lower compartment. Pairs of containers, one with 26 μm mesh and the other with <10 μm mesh, were buried under Pinus radiata seedlings for 10 months in a forest plantation. The effect of ectomycorrhizal (ECM) hyphal activity on phosphate rock dissolution and soil properties was determined. The increased ECM hyphal activity induced increased soil acidification and promoted greater production of acid phosphatase enzyme, causing greater changes in phosphorus (P) fractions in the rhizosphere soils. The increased ECM hyphal activity also stimulated higher dissolution of phosphate rock and mobilization of soil organic P. The results suggest that ECM hyphal strand has a significant role in mobilizing low-solubility P forms and soil organic P for utilization by the tree. Copyright © Taylor & Francis Inc.

Cross-flow ultrafiltration (CFUF) was developed first for the isolation of natural colloids and subsequently for determining the partition of selected endocrine-disrupting chemicals (EDCs) between river colloids and dissolved phase. In this study, a 1-kDa Millipore Pellicon 2 cartridge type CFUF system was validated using a range of molecular probes spiked in natural waters. Results show that good retention (>80%) of high molecular weight (HMW, >1 kDa) molecules and low retention of low molecular weight (LMW, <1 kDa) molecules can be achieved at high concentration factor (cf) values in sampling mode or over long time scales in recirculation mode. The interactions between aquatic colloids and EDCs were studied by mixing EDCs, water, and colloids previously isolated by CFUF for a certain duration, followed by the separation of the target compounds between the truly dissolved and colloid-bound phases by CFUF and analysis by gas chromatography-mass spectrometry (GC-MS). The kinetics of EDCs binding to colloids were relatively rapid, reaching equilibrium within 5 min. The mass balance of chosen EDCs through CFUF system was fully investigated, with good recovery for the relatively polar EDCs such as estrone and 17β-estradiol. On the basis of EDC sorption by colloids, the partition coefficient normalized to colloidal organic carbon content (Kcoc) was 8.85 × 103, 1.50 × 104, 8.85 × 10 3, 4.87 × 104, and 1.59 × 104 mL/g for bisphenol A, estrone, 17β-estradiol, 17α-ethynylestradiol, and 16α-hydroxyestrone, respectively, which are comparable with the values reported in the literature. In addition, it has been shown that the K coc values of EDCs were relatively independent of their octanol-water partition coefficient (Kow) values, suggesting the important role of different binding mechanisms other than nonspecific hydrophobic interaction between EDCs and natural colloids. As the CFUF-GC-MS method can be used to quantify very low concentration of pollutants and is n...

The dissolution rate of magnesium (Mg) fertilisers controls their effectiveness in supplying Mg to plants and the potential for fertiliser-Mg to be lost via leaching. Results from a field trial, conducted on pasture on an Immature Orthic Pumice Soil (pHwater 6.3) treated with different types of Mg fertilisers (100 kg Mg ha–1), showed that Mg dissolution over a 29-month period differed, being 15–20% for serpentine rock products, 50–98% for acidulated serpentine products, 95% for E-mag (magnesium oxide), and 98% for Epsom salts. The percentage dissolution of applied fertiliser-Mg was related to the water solubilities for all the fertilisers except E-mag, which had a high dissolution rate in soil but a very low solubility in water. However, E-mag had high Mg solubility in citric acid, consistent with its dissolution rate in soil. Epsom salts, E-mag, and acidulated serpentine products significantly increased exchangeable Mg in soil samples collected 9 and 29 months after fertiliser application, whereas the unacidulated serpentine rock increased exchangeable Mg only in soil samples collected after 29 months and only when it was re-applied annually for 3 years. The recovery of fertiliser Mg in pasture herbage was positively related to the Mg dissolution rate over the duration of the trial, being 4–8% for serpentine rock products, 19–22% for acidulated serpentine products, 17% for E-mag, and 25% for Epsom salts. For all fertilisers, except E-mag, total recovery of fertiliser Mg in the soil (0–15 cm depth) and herbage combined was lower for fertilisers with the higher rates of Mg dissolution, being 51% for Epsom salts, 53–90% for acidulated serpentine products, 91–95% for serpentine rock products, and 90% for E-mag. Fertiliser Mg not recovered was assumed to have been leached below the 0–15 cm soil depth (49% for Epsom salts, 10–47% for acidulated serpentine products, 5–9% for serpentine products, and 10% for E-mag). The very high fertiliser Mg recoveries in soil (0–15 c...

Measuring pH of soil samples (at four to five depths down to 300 mm) collected three times from a long-term (16 years) field trial involving annual application of six forms of phosphate fertilizers at the rate of 30 kg P ha -1 yr-1 showed that soil acidity in all treatments, including the untreated control, increased with time. The rates of acidification (pH unit yr-1 during the first 10 years) in the topsoil (0-75 mm depth) were in the order, diammonium phosphate (0.038)>control, single superphosphate>Jordan partially acidulated phosphate rock (JPAPR)>North Carolina partially acidulated phosphate rock (NCPAPR), Jordan phosphate rock (JPR)>North Carolina phosphate rock (NCPR) (0.010). Of the 480 kg P ha -1 applied over the 16 year period, 71 and 57% of P from NCPR and JPR dissolved. The theoretical liming values derived from the dissolution of NCPR and JPR were 1698 and 1303 kg CaCO3 ha-1 respectively. Liming values of the two PRs calculated from the increase in soil pH over control treatment (ΔpH) down to 300 mm soil depth were 640 and 414 kg CaCO3 ha-1 for NCPR and JPR, respectively. The lower liming values estimated from the ΔpH method is probably due to proton transfer resulting from the secondary reactions of dissolved fertilizer phosphate with soil constituents, the unaccounted liming effect of the PRs below 300 mm soil depth and the lower soil pH buffering capacities measured from a short-term pH titration method used in the estimation of the liming values. The results of this long-term field study showed that continuous use of certain phosphate rocks (PRs) can significantly slow down the rate of acidification in pastoral soils. © Springer 2005.

The sequential extraction procedure currently used to measure magnesium (Mg) fertilizer dissolution in soils consists of removing dissolved Mg (step 1), and partially dissolved Mg (step 2), followed by an 18-h extraction with 2 M HCl at room temperature to determine undissolved Mg (step 3). This procedure is satisfactory for soluble and moderately soluble Mg fertilizers but is not an accurate procedure for slightly soluble fertilizers, such as serpentine. When step 3 is replaced by a digestion procedure using 2 M HCl for 4 h at 90-95°C (improved step 3), the total serpentine Mg recovery (dissolved and undissolved Mg) from soil samples, either immediately after serpentine was added to soil or after a 21-day incubation with moist soil, was about 100% compared to 40-50% by the original procedure. The improved procedure also increased the recovery of serpentine Mg applied to field soils. Therefore, this study recommends that the third step of the sequential extraction procedure be replaced by a 4 h digestion using 2 M HCl (90-95°C). Copyright © Taylor & Francis, Inc.

Single-stage power-factor-corrected AC-DC converters (S2PFCCs) usually suffer from high current and voltage stresses due to the repeated process of input power through the power switch and power imbalance between the input and output, respectively. The paper presents a detailed analysis of an improved single-switch S2PFCC with an auxiliary transformer, which provides a direct linkage between the input and output stages of the converter. The auxiliary transformer is the key to reducing the voltage stress across the storage capacitor on decreasing load, to reduce the current stress on the power switch and to obtain a high power factor through elimination of input-current dead angle. Detailed analyses of the component stresses and the input current relating to the circuit parameters are presented. The theoretical analysis and effectiveness of the proposed approach are confirmed experimentally with a 15 V 60 W hardware prototype. © IEE, 2005.

Linear micromotors play a key role in microrobotic systems. They can greatly simplify the drive mechanisms, which is crucial for microsystems. By using permanent magnets, much higher force-to-volume ratio can be obtained than using electromagnets and better drive performance can be achieved. This paper describes the development of a tubular permanent magnet linear motor for the actuation of microrobots. Important design criteria are established by both analytical and numerical methods. The field distribution, the electro-magnetic force, and the stator phase winding inductances are analyzed and predicted by the finite-element analysis taking into account the nonlinear properties and saturation effects of the material. © 2005 IEEE.

A mathematic model for topology optimization of continuum structures is developed using SIMP interpolation scheme and the method of moving asymptotes(MMA) in the paper. The intermediate density in optimized structure is investigated, and a rational range for exponent of SIMP model is obtained. The numerical instability problems such as checkerboards and mesh dependencies are also discussed, and these numerical problems are settled through a kind of sensitive filter method. The flowchart for topology optimization is figured out, and a simple software for two dimensional linear elastic structures is developed. The optimal results of several examples show the efficiency of these methods proposed in the paper.

Topology optimization problems for compliant mechanisms using a density interpolation scheme, the rational approximation of material properties (RAMP) method, and a globally convergent version of the method of moving asymptotes (GCMMA) are primarily discussed. First, a new multi-objective formulation is proposed for topology optimization of compliant mechanisms, in which the maximization of mutual energy (flexibility) and the minimization of mean compliance (stiffness) are considered simultaneously. The formulation of one-node connected hinges, as well as checkerboards and mesh-dependency, is typically encountered in the design of compliant mechanisms. A new hybrid-filtering scheme is proposed to solve numerical instabilities, which can not only eliminate checkerboards and mesh-dependency efficiently, but also prevent one-node connected hinges from occurring in the resulting mechanisms to some extent. Several numerical applications are performed to demonstrate the validity of the methods presented in this paper

A modified mathematical model as well as a modified iterative pattern for topology optimization of linear elastic continuum is proposed based on RAMP (Rational Approximation of Material properties) interpolation scheme and the Optimality Criteria Method, where minimization compliance is regarded as the objective. Numerical instabilities, such as checkerboards and mesh dependencies, are also surveyed and investigated. Considering the undesirable numerical side effects when the sensitivity filtering method is applied, a new hybrid filtering method is presented, which can improve side effects and eliminate numerical problems effectively. The methodologies for topological optimization presented in this paper are programmed using FORTRAN. To substantiate the efficiency of these methods adopted in this paper, illustrated examples are presented both for verification and application.

This work presents a methodology for fully compliant micro-mechanism design using continuum topological optimization method. The multi-objective optimization model is established by using compromise programming scheme, in which a kinernatical function and a structural function are both applied to indicate the demands of mechanism flexibility and structure stiffness, and the sensitivities for compliant mechanism optimization design are performed by adopting the adjoint sensitivity analysis method. A globally convergent method of moving asymptotes (GCMMA) is worked out based on the method of moving asymptotes (MMA) belonging to convex programming methods. Numerical instabilities occurring in resulting mechanism are also investigated and a modified SIMP density-stiffness interpolation scheme is suggested not only to eliminate checkerboards and mesh-dependency, but also to improve the one-node connected hinges. The typical application, a micro inverter mechanism, is employed to demonstrate the validation of the algorithms presented in this work. A procedure has been suggested to convert the topological optimization results to a CAD model, and the prototype has also been fabricated as the proof of concept design by laser manufacturing technology.

Autonomic behaviours in network operations will alleviate much of the labour intensive and error prone interventions of today's complex networks. The Service Provider must be able to manage the infrastructure and services at an abstract level, focusing on what the desired behaviour should be rather than how it might be specifically achieved. Policy-Based Network Management (PBNM) appears as one of the leading mechanisms to describe desired behaviours and abstract the programmability of an autonomic network infrastructure to the Service Provider. For massive-scale and complex networks, the current understanding of the Higher Level to Lower Level (HL→LL) refinement process commonly used in PBNM today is not completely effective. One problem encountered is the need to provide a bind mechanism between Higher Level and Lower Level policy specifications such that cross-layer policy requests in the policy continuum can be made by lower policy layers in a dynamic policy refinement cycle (LL→HL→LL). In this paper, we illustrate the problem with a policy-based simple admission control (SAC) application. We then show that policy specifications with a join operator (times sign closed) simplify the SAC specification. We also investigate the performance considerations of this enhancement in Internet size applications. Our future goal is to provide a policy inference engine that can support complex specifications appropriate for PBNM systems that support autonomic behaviours in large networks, made of Network elements with realistic memory and processing constraints. © IFIP International Federation for Information Processing 2005.

Phaeochromocytoma is a neural-crest-derived tumour that may be a feature of several familial cancer syndromes including von Hippel-Lindau (VHL) disease, multiple endocrine neoplasia type 2 (MEN 2), neurofibromatosis type 1 (NF1) and germline succinate dehydrogenase subunit (SDHB and SDHD) mutations. However the somatic genetic and epigenetic events that occur in phaeochromocytoma tumourigenesis are not well defined. Epigenetic events including de novo promoter methylation of tumour-suppressor genes are frequent in many human neoplasms. As neuroblastoma and phaeochromocytoma are both neural-crest-derived tumours, we postulated that some epigenetic events might be implicated in both tumour types and wished to establish how somatic epigenetic alterations compared in VHL-associated and sporadic phaeochromocytomas. We identified frequent aberrant methylation of HIC1 (82%) and CASP8 (31%) in phaeochromocytoma, but both genes were significantly more methylated in VHL phaeochromocytomas than in sporadic cases. Of four tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) receptors analysed, DR4 was most commonly methylated (41%; compared with DcR2 (26%), DcR1 (23%) and DR5 (10%)). Gene methylation patterns in phaeochromocytoma and neuroblastoma did not differ significantly suggesting overlapping mechanisms of tumourigenesis. We also investigated the role of 11p15.5-imprinted genes in phaeochromocytoma. We found that in 10 sporadic and VHL phaeochromocytomas with 11p15.5 allele loss, the patterns of methylation of 11p15.5-differentially methylated regions were consistent with maternal, rather than, paternal chromosome loss in all cases (P<0.001). This suggests that 11p15.5-imprinted genes may be implicated in the pathogenesis of both familial (germline VHL

Purpose - The main objective of this paper is to investigate information system (IS) supported coordination in knowledge-intensive business processes. These are business processes that cannot be pre-defined as their models evolve during process execution from the accumulated experience. Consequently, these processes require a high level of knowledge-sharing, collection and reuse among all participants in the process. Design/methodology/approach - The paper offers a critical analysis of the main limitations of workflow technology that is widely considered to be the leading process-oriented, coordination technology. It illustrates why this technology cannot be used to support coordination in knowledge-intensive business processes. The paper then identifies a number of requirements for possible IS support. Findings - The main conclusion of this paper is that coordination in knowledge-intensive processes is, in fact, a knowledge-intensive process itself, and as such it cannot be fully pre-defined. Therefore, automation of this process is neither desirable nor possible. Practical implications - Each IS requirement, proposed in this paper, identifies a number of further research and implementation challenges related to support of knowledge-intensive business process. They will be of interest to researchers and practitioners both in the fields of business process management as well as knowledge management. Originality/value - In essence, this paper argues that knowledge-intensive business processes require fundamentally different coordination support from what is currently available in the area of business process support. This paper shifts the main emphasis from process automation to IS support for situated decision-making. © Emerald Group Publishing Limited.

Abstract Among the potential risk factors for fragility fractures, bone turnover is considered an important determinant. In a case-cohort control study of 151 elderly men followed prospectively over 6.3 years, high bone resorption as assessed by S-ICTP was associated with increased risk of osteoporotic fracture, independent of BMD. Combining measurements of BMD and bone turnover may improve fracture prediction in elderly men. Introduction: Approximately one-third of osteoporotic fractures occur in men. Among the potential risk factors for fragility fractures, bone turnover is considered an important determinant. The association between fracture risk and rates of bone turnover has not been well established in men. We examined this relationship in elderly community-dwelling men. Materials and Methods: This case-cohort control study included 50 men with incident low-trauma fractures (cases; age, 72.3 ± 6.7 years) and 101 men without fracture (controls; age, 70.4 ± 4.1 years), who have been prospectively followed in the Dubbo Osteoporosis Epidemiology Study for a median of 6.3 years (range, 2-13 years). BMD at the lumbar spine (LSBMD) and at the femoral neck (FNBMD) and markers of bone turnover were measured at baseline. Bone resorption was assessed by measuring nonfasting serum concentrations of the carboxyterminal cross-linked telopeptide of type I collagen (S-ICTP) and of a linear octapeptide derived from the carboxyterminal type I collagen telopeptide (S-CTX). Bone formation was assessed by measuring the serum levels of the aminoterminal propeptide of type I procollagen (S-PINP). Results: Men with subsequent fractures had lower BMD at baseline, both at the femoral neck and the spine, lower dietary calcium intake, and higher S-ICTP levels than age-and weight-matched controls. Smoking habits, S-CTX, and S-PINP did...

SummaryObjective Measurement of biochemical markers of the IGF‐system and of collagen turnover is a potential approach to detect GH abuse in sport. These markers are increased in patients on dialysis treated with recombinant human erythropoietin (r‐HuEPO), mimicking the effects of GH. The aim was to determine whether r‐HuEPO induces similar effects on the IGF‐system and collagen turnover in healthy athletes.Subjects and measurements Young male Caucasian recreational athletes were administered 50 U/kg r‐HuEPO (n = 14) or placebo (n = 16) three times a week for 25 days, followed by a 4‐week wash‐out period. IGF‐I, IGFBP‐3, the acid labile subunit (ALS), N‐terminal propeptide of type I collagen (PINP), C‐terminal telopeptide of type I collagen (ICTP) and N‐terminal propeptide of type III collagen (PIIINP) were measured in samples collected at baseline (two samples), after 10, 22 and 24 days of r‐HuEPO treatment and at the end of the 4‐week wash‐out period.Results Treatment with r‐HuEPO resulted in approximately threefold elevation of serum EPO and marked elevation of markers of erythropoiesis. There was no significant treatment effect of r‐HuEPO compared to baseline on IGF‐I, IGFBP‐3, ALS, PINP, ICTP or PIIINP.Conclusions r‐HuEPO administration did not change markers of the IGF‐system and of collagen turnover in young healthy male athletes. Therefore, use of r‐HuEPO in athletes should not affect the validity of a GH doping test using these GH‐responsive markers.

AbstractBackgroundFat mass, which is a major component of body weight, is directly related to bone mineral density and reduced fracture risk. It is not known whether abdominal fat is associated with hip fracture. The present study was designed to examine the association between abdominal fat and hip fracture in women and men aged 60+ years.MethodsThis was a nested case-control study with one fracture case being matched with two controls of the same age. In women 63 cases were matched with 126 controls, and in men 26 cases were matched with 52 controls. Hip fracture was confirmed by X-ray and personal interview. Other measurements included weight, height, body mass index (BMI), abdominal fat, and femoral neck bone density (FNBMD). Conditional logistic regression model was used to analyse data.ResultsThe odds ratio of hip fracture risk associated with each 10% lower abdominal fat was 1.5 (95% CI, 1.1 to 2.1) in women and 1.2 (95% CI, 0.7 to 2.0) in men. However after adjusting for FNBMD or body weight, the abdominal fat-fracture association was no longer statistically significant. Similarly, body weight and BMI was each significantly associated with hip fracture risk (in women), but after taking with account the effect of FNBMD, the association become statistically non-significant.ConclusionLower abdominal fat was associated with an increased risk of hip fracture in elderly women, but the association was not independent of FNBMD or weight. The contribution of abdominal fat to hip fracture risk is likely to be modest.

AbstractIn this 14‐year prospective study, men and women were found to share a common set of risk factors for hip fracture: low BMD, postural instability and/or quadriceps weakness, a history of falls, and prior fracture. The combination of these risk factors accounted for 57% and 37% of hip fractures in women and men, respectively.Introduction: Risk factors for hip fracture, including low BMD, identified in women, have not been shown to be useful in men. It is also not known whether fall‐related factors (muscle strength and postural instability) predict hip fracture. This study examined the association between falls‐related factors and hip fractures in elderly men and women.Materials and Methods: This is an epidemiologic, community‐based prospective study, which included 960 women and 689 men ≥60 years of age who have been followed for a median of 12 years (interquartile range, 6–13). The number of person‐years was 9961 for women and 4463 for men. The outcome measure was incidence of hip fracture. Risk factors were femoral neck BMD (FNBMD), postural sway, quadriceps strength, prior fracture, and fall.Results: Between 1989 and 2003, 115 (86 women) sustained a hip fracture. The risk of hip fracture (as measured by hazards ratio [HR]) was increased by 3.6‐fold (95% CI: 2.6–4.5) in women and 3.4‐fold (95% CI: 2.5–4.6) in men for each SD (0.12 g/cm2) reduction in FNBMD. After adjusting for BMD, the risk of hip fracture was also increased in individuals with the highest tertile of postural sway (HR: 2.7; 95% CI: 1.6–4.5) and low tertiles of quadriceps strength (HR: 3.0; 95% CI: 1.3–6.8). Furthermore, a history of fall during the preceding 12 months and a history of fracture were independent predictors of hip fracture. For each level of BMD, the risk of hip fracture...

Cultivated chickpea germplasm collections contain a low frequency of ascochyta blight resistant accessions. This might lead to limitations on the future progress of chickpea breeding worldwide. In an effort to identify novel sources of resistance to ascochyta blight, 56 unique accessions, comprising 8 annual wild Cicer species, were evaluated under a controlled environment that was optimal for infection with an aggressive Australian isolate of Ascochyta rabiei (Pass.) Labrousse. The majority of wild Cicer accessions were either susceptible or highly susceptible to A. rabiei 21 days after inoculation; however, 11 accessions, of which 7 were Cicer judaicum, were resistant. The most resistant accession detected in this study, ATC 46934, together with accessions ATC 46892 and ATC 46935, which were resistant in this and another study, should be targeted for use in future interspecific resistance breeding programs.

Abstract Whereas low BMD is known to be a risk factor for fracture, it is not clear whether loss of BMD is also a risk factor. In elderly women, greater loss of BMD at the femoral neck was associated with increased risk of fracture, independent of baseline BMD and age. Introduction: Baseline measurement of BMD predicts fracture risk. However, it is not clear whether short-term bone loss is an independent risk factor for fractures. This study was designed to investigate the relationship between changes in BMD and fracture risk in elderly women in the general population. Materials and Methods: A total of 966 women ≥60 years of age (mean, 70 ± 6.7 [SD] years), who had been followed for an average of 10.7 years, were studied. Atraumatic fracture of the proximal femur (hip), symptomatic vertebral fracture, and other major fractures, excluding pathological fractures or those resulting from severe trauma, were recorded and confirmed by radiographs. Femoral neck and lumbar spine BMD was measured by DXA. Results: During the follow-up period, 224 had sustained a fracture (including 43 hip, 71 symptomatic vertebrae, 37 proximal humerus, 46 forearm and wrist, and 27 rib and pelvis fractures). The annual rate of change in BMD in fracture women (−2.1 ± 4.2%) was significantly higher than that in nonfracture women (−0.8 ± 2.8%; p = 0.005). In the multivariable Cox's proportional hazards analysis, the following factors were significant predictors of fracture risk: femoral neck bone loss (relative hazard [RH], 1.4; 95% CI, 1.1-1.8 per 5% loss), baseline femoral neck BMD (RH, 2.0; 95% CI, 1.7-2.7 per SD), and advancing age (RH, 1.2; 95% CI, 1.1-1.4). The proportion of fractures attributable to the three factors was 45%. For hip fracture, the attributable risk fraction was ∼90%. Conclusion: Bone los...

G protein-coupled receptors occur as dimers within arrays of oligomers. We visualized ensembles of dopamine receptor oligomers in living cells and evaluated the contributions of receptor conformation to the dynamics of oligomer association and dissociation, using a strategy of trafficking a receptor to another cellular compartment. We incorporated a nuclear localization sequence into the D1 dopamine receptor, which translocated from the cell surface to the nucleus. Receptor inverse agonists blocked this translocation, retaining the modified receptor, D1-nuclear localization signal (NLS), at the cell surface. D1 co-translocated with D1-NLS to the nucleus, indicating formation of homooligomers. (+)-Butaclamol retained both receptors at the cell surface, and removal of the drug allowed translocation of both receptors to the nucleus. Agonist-nonbinding D1(S198A/S199A)-NLS, containing two substituted serine residues in transmembrane 5 also oligomerized with D1, and both were retained on the cell surface by (+)-butaclamol. Drug removal disrupted these oligomerized receptors so that D1 remained at the cell surface while D1(S198A/S199A)-NLS trafficked to the nucleus. Thus, receptor conformational differences permitted oligomer disruption and showed that ligand-binding pocket occupancy by the inverse agonist induced a conformational change. We demonstrated robust heterooligomerization between the D2 dopamine receptor and the D1 receptor. The heterooligomers could not be disrupted by inverse agonists targeting either one of the receptor constituents. However, D2 did not heterooligomerize with the structurally modified D1(S198A/S199A), indicating an impaired interface for their interaction. Thus, we describe a novel method showing that a homogeneous receptor conformation maintains the structural integrity of oligomers, whereas conformational heterogeneity disrupts it. © 2005 by The American Society for Biochemistry and Molecular Biology, Inc.

PurposeOver the past 50 years India has been experiencing rapid population growth, causing the migration of a large part of the population to the cities looking for livelihood. This resulted in massive increments of population in the cities that has led to the increase of pollution. Gujarat, being a highly industrialized state, is a case in point. The systems for treatment and water disposal of this state are highly challenged. The north‐western state of Gujarat has no effective systems for treatment or disposal of waste water. The purpose of this article is to address this problem, introducing a geographic information system (GIS) approach to record the characterization, analyze the needs and generate a conceptual GIS database in the state.Design/methodology/approachThis paper outlines the background, suggested methodology for the development of a GIS database pollution dependent control of water pollution in the state of Gujarat in India. The present research is to install a document management system that has been developed in providing organizing chart, sorting, querying and retrieving of key data.

AbstractObjective: To develop and validate sex‐specific equations for predicting percentage body fat (%BF) in rural Thai population, based on BMI and anthropometric measurements.Research Methods and Procedures: %BF (DXA; GE Lunar Corp., Madison, WI) was measured in 181 men and 255 women who were healthy and between 20 and 84 years old. Anthropometric measures such as weight (kilograms), height (centimeters), BMI (kilograms per meter squared), waist circumference (centimeters), hip circumference (centimeters), thickness at triceps skinfold (millimeters), biceps skinfold (millimeters), subscapular skinfold (millimeters), and suprailiac skinfold (millimeters) were also measured. The sample was randomly divided into a development group (98 men and 125 women) and a validation group (83 men and 130 women). Regression equations of %BF derived from the development group were then evaluated for accuracy in the validation group.Results: The equation for estimating %BF in men was: %BF(men) = 0.42 × subscapular skinfold + 0.62 × BMI − 0.28 × biceps skinfold + 0.17 × waist circumference − 18.47, and in women: %BF(women) = 0.42 × hip circumference + 0.17 × suprailiac skinfold + 0.46 × BMI − 23.75. The coefficient of determination (R2) for both equations was 0.68. Without anthropometric variables, the predictive equation using BMI, age, and sex was: %BF = 1.65 × BMI + 0.06 × age − 15.3 × sex − 10.67 (where sex = 1 for men and sex = 0 for women), with R2 = 0.83. When these equations were applied to the validation sample, the difference between measured and predicted %BF ranged between ±9%, and the positive predictive values were above 0.9.Discussion: These results suggest that simple, n...

AbstractIn elderly men and women, asymptomatic vertebral deformity was found to be associated with subsequent risk of symptomatic fractures, particularly vertebral fracture, and increased risk of mortality after a fracture.Introduction: Vertebral deformity is associated with an increased risk of fracture and mortality. However, it is unclear whether the three events of vertebral deformity, fracture, and mortality are linked with each other and what role BMD plays in these linkages.Materials and Methods: Vertebral deformity was determined from quantitative analysis of thoracolumbar spine X‐rays in 300 randomly individuals (114 men and 186 women) ⩾60 years of age (as of mid‐1989), who were randomly selected from the prospective Dubbo Osteoporosis Epidemiology Study. Incidence of atraumatic fractures and subsequent mortality were ascertained from 1989 to 2003. Cox's proportional hazards model was used to determine the association between asymptomatic vertebral deformities, osteoporotic fractures, and risk of mortality.Results: The prevalence of asymptomatic vertebral deformity was 31% in men and 17% in women. During the follow‐up period, subjects with vertebral deformity had a significantly higher risk of any fracture than those without vertebral deformity (44% versus 29%; hazards ratio [HR], 2.2; 95% CI, 1.4‐3.7), particularly symptomatic vertebral fracture (relative risk [RR], 7.4; 95% CI, 3.2‐17.0). Mortality rate was highest after a symptomatic fracture among those with vertebral deformity (HR, 9.0; 95% CI, 3.1‐26.0). These associations were independent of age, sex, and BMD.Conclusion: Vertebral deformity was a strong predictor of subsequent risk of fractures, particularly symptomatic vertebral fracture, and may modify fracture‐associated m...

The authors examined the areal bone mineral density (aFNBMD) and estimated volumetric bone mineral density at the femoral neck (vFNBMD) in rural Thai men and women. A total of 181 men and 255 women, between 20 and 84 years of age, living in rural areas of Khon Kaen province, were randomly selected. Areal FNBMD and estimated v FNBMD were determined using dual energy X-ray absorptiometry (DPX-IQ, GE Lunar Corp, Madison, WI). Men had a significantly higher aFNBMD than women, whereas the estimated vFNBMD was similar regardless of sex. The peak for the aFNBMD vs. vFNBMD was observed between 20 and 29 vs. 30 and 39 years of age in men and women, respectively. The prevalence of osteoporosis in men and women using estimated vFNBMD vs. aFNBMD cut-offs was 19 and 14.2 vs 11.8 and 26 percent, respectively. Prevalence increased with age. Estimated vFNBMD shows only small sex-correlated differences in bone density. Estimated vFNBMD was more sensitive than aFNBMD, when used to define the osteoporotic cut-offs in men, while it was less sensitive than aFNBMD in women.

Abstract Background The incidence of fractures in rural populations is lower than in urban populations, although the reason for this difference is unclear. This cross-sectional study was designed to examine the difference in bone mineral density (BMD), a primary predictor of fracture risk, between urban and rural Thai populations. Methods Femoral neck and lumbar spine BMD was measured by dual-energy X-ray absorptiometry (GE Lunar, Madison, WI) in 411 urban and 436 rural subjects (340 men and 507 women), aged between 20 and 84 years. Body mass index (BMI) was calculated from weight and height. Results After adjusting for age and body weight in an analysis of covariance model, femoral neck BMD in rural men and women was significantly higher than those in urban men and women (P < 0.001), but the difference was not observed at the lumbar spine. After stratifying by sex, age group, and BMI category, the urban-rural difference in femoral neck BMD became more pronounced in men and women aged <50 years and with BMI ≥ 25 kg/m2. Conclusions These data suggest that femoral neck BMD in rural men and women was higher than their counterparts in urban areas. This difference could potentially explain part of the urban-rural difference in fracture incidence.

Abstract Choline kinase is overexpressed in human breast, lung, colorectal, and prostate tumors, a finding that suggests the involvement of this enzyme in carcinogenesis. Here we show that overexpression of choline kinase induce oncogenic transformation of human embryo kidney fibroblasts and canine epithelial Madin-Darby canine kidney cells. Choline kinase lays downstream of RhoA signaling and is activated through ROCK kinase, one of the best-characterized RhoA effectors. In keeping with this, coexpression of RhoA and choline kinase potentiates both anchorage independent growth and tumorigenesis. Finally, choline kinase–mediated transformation is sensitive to MN58b, a well-characterized specific choline kinase inhibitor. These results provide the definitive evidence that choline kinase has oncogenic properties and that choline kinase inhibition constitutes a novel valid antitumor strategy.

Depression prevalence was examined by race/ethnicity in a nationally representative sample. The Diagnostic Interview Schedule was administered to 8449 (response rate=96.1%) participants (aged 15–40 years). Prevalence of major depressive disorder was significantly higher in Whites than in African Americans and Mexican Americans; the opposite pattern was found for dysthymic disorder. Across racial/ethnic groups, poverty was a significant risk factor for major depressive disorder, but significant interactions occurred between race/ethnicity, gender, and education in relation to prevalence of dysthymic disorder.

Individual classification models are recently challenged by combined pattern recognition systems, which often show better performance. In such systems the optimal set of classifiers is first selected and then combined by a specific fusion method. For a small number of classifiers optimal ensembles can be found exhaustively, but the burden of exponential complexity of such search limits its practical applicability for larger systems. As a result, simpler search algorithms and/or selection criteria are needed to reduce the complexity. This work provides a revision of the classifier selection methodology and evaluates the practical applicability of diversity measures in the context of combining classifiers by majority voting. A number of search algorithms are proposed and adjusted to work properly with a number of selection criteria including majority voting error and various diversity measures. Extensive experiments carried out with 15 classifiers on 27 datasets indicate inappropriateness of diversity measures used as selection criteria in favour of the direct combiner error based search. Furthermore, the results prompted a novel design of multiple classifier systems in which selection and fusion are recurrently applied to a population of best combinations of classifiers rather than the individual best. The improvement of the generalisation performance of such system is demonstrated experimentally. © 2004 Elsevier B.V. All rights reserved.

A direct and indirect change in the ownership of significant segments of the electricity industry -from the public to the private arena - has been an accompaniment to the structural and regulatory reform of the Australian electricity industry, underway for much of the last decade. While the structural and regulatory aspects of reform have engendered considerable public debate, the debate on the various aspects of the change in ownership - its rationale, methods, and impacts - has however been rather narrow, largely opaque, and mostly surreptitious, confined almost exclusively to the immediate fiscal impacts of the sale of electricity assets. It lacks any substantive consideration of the historical, political, and philosophical underpinnings of this change, and the profound, variegated, and fundamental consequences that this change will inevitably induce in terms of redistributing wealth in society, recasting the balance between the market and the welfare state, reorganizing the institutions of governance, realigning economic and political interests, reinterpreting of the role of the state, and indeed a rethinking on the philosophical foundations of a civilized society. This paper provides reconnoiter of the political and philosophical connects of the change in the ownership of the Australian electricity industry and argues for the need to broaden the nature of the current debate on these issues. While the review focuses on the Australian electricity industry, the messages are relevant for other countries undertaking reform, especially developing countries as they begin to dismantle and privatize their electricity infrastructures.

Outliers are data values that lie away from the general cluster of other data values. Detecting the outliers of a dataset is an important research topic for data cleaning and finding new useful knowledge in many research areas, i.e. data mining, pattern recognition, etc. In the past decades, many useful algorithms were proposed in the literature. In this paper, a new fuzzy kernel-clustering algorithm with outliers (FKCO) is presented to locate critical areas that are often represented by only a few outliers. Theoretic analysis also shows that FKCO can converge to a local minimum of the objective function. Finally, based on the information theory, a new criterion for finding outliers is also proposed. Simulations of different types of datasets demonstrate the feasibility of this new method. © 2005 JD.

Conventional clustering algorithms are designed for a single independent dataset, e.g. Fuzzy C-Means (FCM) clustering algorithm. In real world, a dataset is independent of other datasets but sometimes can be cooperative with others by exchanging information, such as the relationship between the subsidiary companies. So the influence from other relative collaborative datasets should be considered while performing clustering learning under such collaborative circumstances. Two different collaborative models are discussed and new proper methods are proposed to quantitatively measure such collaboration between datasets in this paper, e. g. information gain. The corresponding collaborative clustering algorithms are presented accordingly and the theoretic analysis shows that the new cooperative clustering algorithms can finally converge to local minimum. Experimental results demonstrate that the clustering structures obtained by new cooperative algorithms are different from those of conventional algorithms for the consideration of collaboration and the performances of these collaborative clustering algorithms can be much better than those conventional single clustering algorithms under the cooperating circumstances.

Rigorous design of interactive slab-ground foundation systems on expansive soils remains as a challenge for both practitioners and researchers. Attempts to solve these problems in a generalized way usually involve substantial approximations and have limited success. In this paper, a simple soil behaviour model is adapted into a new finite element formulation. The success of the approach is evaluated by comparing predicted foundation movements with those measured at the Maryland expansive soils field site. In particular, the computed vertical displacements are compared with field measurements. The numerical solutions are generally in good agreement with the observed data.

In this research, a NTR 729HF nanofiltration (NF) membrane was employed to remove synthetic organic matter (SOM) from wastewater. NF alone led to a removal of 92.4% of dissolved organic carbon (DOC). The performance of NF was compared with that of a microfiltration (MF) hybrid system consisting of FeCl3 flocculation, MF and photocatalysis. Flocculation and microfiltration followed by photocatalysis led to more than 96% dissolved organic carbon (DOC) removal. A detailed molecular weight (MW) distribution study of organic matter indicated that the photocatalysis initially breaks the large MW organics and then the small MW organics were removed by a photoreactor process. Flocculation with an optimum dose of FeCl3 (68 mg/L as FeCl3) gave rise to the highest removal of organics including small MW organics. The small MW organics remaining after the treatment of flocculation could successfully be removed by photocatalysis.

Membrane fouling is a critical limitation on the application of membranes to wastewater reuse. This work aims to understand the fouling phenomenon which occurs in ultrafiltration (UF; 17500 molecular weight cutoff (MWCO)) and nanofiltration (NF; 250 MWCO) membranes, with and without pretreatment. For this purpose, the molecular weight (MW) distribution of the organics has been used as a parameter to characterize the influent, the permeate, and the foulant on the membrane surface. The variation of foulant concentration on the membrane due to pretreatment of the influent by flocculation and/or adsorption was investigated in detail. With the UF membrane, the peak of the MW distribution of organics in the permeate depended on the pretreatment; for example, the weight-averaged MW (Mw) of 675 without pretreatment shifted down to 314 with pretreatment. In the case of the NF membrane, the Mw of organics in the permeate was 478 (without pretreatment) and 310 (with flocculation followed by adsorption). The Mw of the organics in the foulant on the membrane surface was 513 (UF) and 192 (NF) without pretreatment and 351 (UF) and 183 (NF) after pretreatment with flocculation followed by adsorption, respectively. Without the pretreatment, the foulant concentration was higher on both membranes. The difference was more significant on the UF membrane than on the NF membrane. For both membranes, the flocculation-and-then- adsorption pretreatment proved very effective. © 2005 American Chemical Society.

In this study, different pretreatment methods such as ferric chloride (FeCl3) flocculation and powdered activated carbon (PAC) adsorption were evaluated in terms of their capability in removing effluent organic matter (EfOM) and the characteristics of the foulants on the NF membranes. A detailed experiment was conducted with two NF membranes (NTR 729HF with MWCO 700 daltons and LF 10 with MWCO 200 daltons). With pretreatment, the concentration of organic matter on the membranes decreased to 5.67110+3 (NTR 729HF) and 4.94010+3 (LF 10) mg EfOM/cm2 of membrane from 6.37210+3 (NTR 729HF) and 4.97910+3 (LF 10) mg EfOM/cm2 of membrane. The MW of the solute fraction of biologically treated sewage effluent (BTSE) ranged from 250 daltons to about 3573 (the most important being 250-520 daltons). The weight-averaged MW values of the foulants on the NTR 729HF membrane reduced from 304 daltons without pre-treatment to 208 daltons with pretreatment. In the case of EfOM, the small molecules (MW 300 to 500 daltons) are mainly responsible for the membrane fouling. Thus, the MW distribution of organic matter in the effluent and in the foulant can be used as a representative tool to evaluate the efficiency of pretreatment and NF and in the selection of their operating conditions.

Concentrations of microbiological contaminants in streams increase during rainfall-induced higher flow ‘event’ periods as compared to ‘baseflow’ conditions. If the stream feeds a drinking water reservoir, such periods of heightened pathogen loads may pose a challenge to the water treatment plant and subsequently a health concern to water consumers downstream. In order to manage this risk, it is desirable to first quantify the differences in surface water quality between baseflow and event conditions. The Event Mean Concentration (EMC) is a flow-weighted average concentration of a contaminant over the duration of a single event, proposed here as a standard parameter for quantifying the net effect of events on microbial water quality. Application of the EMC concept was assessed using flow and quality data for several events from an urbanised catchment. Expected mean EMCs were significantly larger than expected mean baseflow concentrations (p-value≤0.012) for three microbial agents - Escherichia coli (13,000 [n = 7] v. 610 [n = 16] mpn/100 ml), Cryptosporidium (234 [n = 6] v. 51 [n = 16] oocysts/10 litres) and Campylobacter (48 [n = 5] v. 2.1 [n = 16] mpn/100 ml). These parameter estimates were complemented by estimating data variability and uncertainty in the form of second-order random variables. As such the results are in a format appropriate for potential use as components in probabilistic risk assessments evaluating the effect runoff events have on drinking water quality.

We provided evidence for the formation of a novel phospholipase C-mediated calcium signal arising from coactivation of D1 and D2 dopamine receptors. In the present study, robust fluorescence resonance energy transfer showed that these receptors exist in close proximity indicative of D1-D2 receptor heterooligomerization. The close proximity of these receptors within the heterooligomer allowed for cross-phosphorylation of the D2 receptor by selective activation of the D1 receptor. D1-D2 receptor heterooligomers were internalized when the receptors were coactivated by dopamine or either receptor was singly activated by the D1-selective agonist (±)-6-chloro-7,8-dihydroxy-1- phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrobromide (SKF 81297) or the D2-selective agonist quinpirole. The D2 receptor expressed alone did not internalize after activation by quinpirole except when coexpressed with the D1 receptor. D1-D2 receptor heterooligomerization resulted in an altered level of steady-state cell surface expression compared with D1 and D2 homooligomers, with increased D2 and decreased D1 receptor cell surface density. Together, these results demonstrated that D1 and D2 receptors formed heterooligomeric units with unique cell surface localization, internalization, and transactivation properties that are distinct from that of D1 and D2 receptor homooligomers.

This paper presents a new control method for processes which can be described by Hammerstein models. The control design is based on the concept of passive systems. The proposed method is based on feedforward passivation and thus can be applied to nonminimum phase processes and/or processes of high relative degree. A synthesis technique for marginally stable positive real systems has been developed to achieve offset free control. The new control design can be easily implemented by solving a set of linear matrix inequalities. The proposed approach is illustrated using the example of an acid-base pH control problem.

Although player enjoyment is central to computer games, there is currently no accepted model of player enjoyment in games. There are many heuristics in the literature, based on elements such as the game interface, mechanics, gameplay, and narrative. However, there is a need to integrate these heuristics into a validated model that can be used to design, evaluate, and understand enjoyment in games. We have drawn together the various heuristics into a concise model of enjoyment in games that is structured by flow. Flow, a widely accepted model of enjoyment, includes eight elements that, we found, encompass the various heuristics from the literature. Our new model, GameFlow, consists of eight elements -- concentration, challenge, skills, control, clear goals, feedback, immersion, and social interaction. Each element includes a set of criteria for achieving enjoyment in games. An initial investigation and validation of the GameFlow model was carried out by conducting expert reviews of two real-time strategy games, one high-rating and one low-rating, using the GameFlow criteria. The result was a deeper understanding of enjoyment in real-time strategy games and the identification of the strengths and weaknesses of the GameFlow model as an evaluation tool. The GameFlow criteria were able to successfully distinguish between the high-rated and low-rated games and identify why one succeeded and the other failed. We concluded that the GameFlow model can be used in its current form to review games; further work will provide tools for designing and evaluating enjoyment in games.

The Goal of this work is to provide a more in depth understanding of the navigation in the autonomous robot using stable visual points derived from the repeated experimentation by the stereo vision in a natural featured environment. In order to identify the position of the robot as well as to establish the 3 D obstacle map under the unknown environment, we discuss the simultaneous stereo type localization and map building (SLAM) problem. The design of the planning algorithm for a vision guided mobile robot depends upon the two main characteristics of visual environmental recognition i.e. Uncertainty and Efficiency. The uncertainty is reduced by the Extended Kalman Filter algorithm based on the process and observation model of the mobile robot. Regarding the efficiency, the optimal path planning algorithm which uses the dynamical localized Voronoi division is a new concept in our proposal. This method has the ability to make the path for mobile robot with only suitable number of natural features.

This paper presents the design and implementation of an autonomous robot navigation system for intelligent target collection in dynamic environments. A feature-based multi-stage fuzzy logic (MSFL) sensor fusion system is developed for target recognition, which is capable of mapping noisy sensor inputs into reliable decisions. The robot exploration and path planning are based on a grid map oriented reinforcement path learning system (GMRPL), which allows for long-term predictions and path adaptation via dynamic interactions with physical environments. In our implementation, the MSFL and GMRPL are integrated into subsumption architecture for intelligent target-collecting applications. The subsumption architecture is a layered reactive agent structure that enables the robot to implement higher-layer functions including path learning and target recognition regardless of lower-layer functions such as obstacle detection and avoidance. The real-world application using a Khepera robot shows the robustness and flexibility of the developed system in dealing with robotic behaviors such as target collecting in the ever-changing physical environment.

A robust optimal preview control method is presented in this paper for path tracking control problems to improve robustness and tracking precision of path tracking control systems. The known path information is used as reference input signals. Simulation results show that this method is valid not only for improving the performance of highly accurate trajectory control but also for improving system stabilization.

AIM: Only a minority of Australian graduates are interested in careers in general practice. The factors influencing medical students toward general practice as a career choice are poorly understood, even though this is important to the makeup of the medical workforce. METHODS: We ran 10 focus groups involving 82 first and final year medical students from three Australian medical schools in 2002, and analysed factors influencing participants' interest in working in general practice. RESULTS: About half the students were interested in general practice. Attractive factors were: the nature of the work (including its diversity), continuity of care, community context, and working conditions (including flexibility of training and work, availability of part time work and portability of qualifications). Negative factors included: the breadth of knowledge needed, boring work (in urban general practice), having to run a business, and working conditions (including relatively poor remuneration, overwork in rural general practice, and poor status of general practitioners). Some students were strongly influenced by negative attitudes of the GPs they were taught by, deciding against general practice as a career. DISCUSSION: Medical educators and GPs should be aware of this important influence.

This paper describes a new type of sequential testing for clinical trials. The sequential nature of the data is not from additional patients, but rather from longer follow-up times. At each analysis, the null hypothesis that all treatments are equivalent in effect on the outcome after that amount of time is tested. The trial might still have staggered entry or not, but the key feature is that a different statistical hypothesis is tested at each analysis. It is assumed that any effect of treatment is non-transient, allowing a conclusion to be drawn in favour of one treatment or the other based on a difference at a single follow-up time. It is shown that a general method based on the Bonferroni inequality can be used to obtain critical cutpoints for sequential testing, that controls the chance of a type I error for the clinical decision. This method is applicable regardless of the test used at each analysis. In the case of a two-armed trial with a Gaussian outcome variable, it is shown how simulation can be used to obtain critical cutpoints that maintain the chance of a type I error for the clinical decision. The methods are compared by Monte-Carlo simulation, and it is seen that in most practical cases the Bonferroni method is not very conservative. The Bonferroni procedure is illustrated on the results of a real clinical trial of Pirfenidone on pulmonary fibrosis in Hermansky-Pudlak Syndrome.

Standard SVM training has O(m3) time and O(m2) space complexities, where m is the training set size. It is thus computationally infeasible on very large data sets. By observing that practical SVM implementations only approximate the optimal solution by an iterative strategy, we scale up kernel methods by exploiting such 'approximateness' in this paper. We first show that many kernel methods can be equivalently formulated as minimum enclosing ball (MEB) problems in computational geometry. Then, by adopting an efficient approximate MEB algorithm, we obtain provably approximately optimal solutions with the idea of core sets. Our proposed Core Vector Machine (CVM) algorithm can be used with nonlinear kernels and has a time complexity that is linear in m and a space complexity that is independent of m. Experiments on large toy and real-world data sets demonstrate that the CVM is as accurate as existing SVM implementations, but is much faster and can handle much larger data sets than existing scale-up methods. For example, CVM with the Gaussian kernel produces superior results on the KDDCUP-99 intrusion detection data, which has about five million training patterns, in only 1.4 seconds on a 3.2GHz Pentium-4 PC.

A catchment modelling system for simulation of both the quantity and quality of stormwater runoff can be considered to consist of four conceptual components, which are generation, collection, transport and disposal. Within each of these components, there are many alternative transformations available, with each of these transformations being the result of different combinations of process models. There are numerous combinations of transformations and information from apreceding component that map to asingle output. The concept ofsystem calibration, therefore, is to select the appropriate transformations and informationfor the catchment being simulated. Within the generation conceptual component, an important aspect is the model used to transform the point rainfall measurements into a spatially distributed rainfall over the catchment. There have been many alternative models proposedfor this transformation. Presented herein is an analysis of the influence ofalternative rainfall models on the simulated hydrograph and hence the influence on the system calibration. This analysis will be based on real events recorded at the outlets ofthe Centennial Park catchment (1.3 km2) and the upper Parramatta River catchment (110 km2) in Sydney, Australia. It will be shown from this analysis that the influence ofthe rainfall model is related to the spatial and temporal variability of the storm event

Measures that improve durability of a structure usually increase its initial cost. Thus, in order to make a decision about a cost-effective solution the life-cycle cost of a structure including cost of structural failure needs to be considered. Due to uncertainties associated with structural properties, loads and environmental conditions the cost of structural failure is a random variable. The paper derives probability distributions of the cost of failure of a single structure and a group of identical structures when single or multiple failures are possible during the service life of a structure. The probability distributions are based on cumulative probabilities of failure of a single structure over its service life. It is assumed that failures occur at discrete points in time, the cost of failure set at the time of decision making remains constant for a particular design solution and the discount rate is a deterministic parameter not changing with time. The probability distributions can be employed to evaluate the expected life-cycle cost or the expected utility, which is then used in decision making. An example, which considers the selection of durability specifications for a reinforced concrete structure built on the coast, illustrates the use of the derived probability distributions. © 2004 Elsevier Ltd.

Many countries, from the US to Australia, are now interested in implementing stand-by power energy label for household appliances, in stages, until the 1-W (watt) target is achieved. TV sets consuming 1-W power are widely available in the developed nations. In a developing country like Malaysia, however, the penetration of 1-W stand-by power TV is very low and unless a mandatory label programme is introduced, the degree of penetration is not likely to rise. This paper attempts to calculate the emission pollutants reduction and the energy savings by implementing the 1-W stand-by power label for TV sets in Malaysia. It is estimated that this effort will enable CO2 (carbon dioxide) emissions reduction of 1477.7 kT (kilo tonnes), NOx (oxides of nitrogen) reduction of 4673.0 tonnes, and CO (carbon monoxide) reduction of 763.7 tonnes in the country during the energy label period of 20 years. Additionally, Malaysia will benefit from energy savings of approximately, 2794.9 GWh (gigawatt hours). © 2005, IOS Press. All rights reserved.

The present study describes an accelerated corrosion testing program comprising eight reinforced concrete (RC) specimens to simulate reinforcement corrosion of a section of a typical RC bridge deck. A constant corrosion rate of approximately 100 μA/cm2 was applied to accelerate the corrosion process in chloride contaminated concrete. Experimental results are compared with existing crack initiation and propagation models. A new empirical model to predict the time to excessive cracking for RC structures subjected to corrosion is proposed for cracks up to 1 mm in width by considering concrete quality and cover as influencing variables. The model is also able to account for time-variant corrosion rates and the effect of a high rate of loading often associated with extrapolating accelerated corrosion test results to real RC structures. It was observed that the accuracy of the predictive model for crack initiation will not significantly influence the time to excessive cracking. The time to excessive cracking is most influenced by the correction factor for rate of loading. Copyright © 2005, American Concrete Institute.

Corrosion-induced cracking is observed to vary spatially over concrete surfaces. A two-dimensional spatial time-dependent reliability model is developed to predict the likelihood and extent of corrosion-induced cracking. The spatial variability of concrete cover, concrete compressive strength, and surface chloride concentration are considered in the spatial time-dependent reliability model. The reliability analysis predicts: (1) probability of the first incidence of cracking, (2) proportion of an area subject to severe cracking, and (3) probability that a given percentage of a concrete surface has cracked. Corrosion-induced crack initiation and propagation models are developed for limit crack widths up to 1 mm. The present paper presents results for a typical reinforced concrete bridge deck. The effect of concrete cover, concrete quality, limit crack width, and environment are considered. It was shown that for poor durability design specifications the likelihood and extent of spalling is high. When combined with a life-cycle cost analysis, this predictive capability enables the extent of future repair costs to be estimated and the optimal durability design specifications or repair/maintenance strategies determined. © ASCE.

AbstractA novel thermoresponsive shell crosslinked three‐layer onion‐like polymer particles were prepared using hyperbranched polyglycerol (PG) as parents compound, the periphery hydroxyl groups of PG were transformed into trithiocarbonates (SC(S)S) first; then, it was used as chain transfer agent to prepare star‐like block copolymer of N‐isopropyl acrylamide (NIPA) and N,N‐dimethylaminoethyl acrylate (DMA) in sequence via reversible addition fragmentation chain transfer (RAFT) process. Thus, a three‐layer polymer, PG[SC(S)S(DMA)b(NIPA)]n, was obtained. The middle layer of poly(DMA) was then crosslinked with 1,8‐diiodoctane, and the resulting onion‐like three‐layer polymer showed a lower critical solution temperature (LCST) in water because of the outer layer of poly(NIPA). The LCST value only slightly depended on the crosslinking degree. Finally, the SC(S)S were transformed into thiols by sequential treating with sodium borohydride and formic acid; thus, the core molecule was chemically detached from the crosslinked shell and a novel shell crosslinked polymer particle was obtained. © 2005 Wiley Periodicals, Inc.

Spiral Architecture (SA) is a novel image structure which has hexagons but not squares as the basic elements. Apart from many other advantages in image processing, SA has shown two unbeatable characters that have potential to improve image compression performance, namely, Locality of Pixel Density and Uniform Image Partitioning. Fractal image compression is a relatively recent image compression method which exploits similarities in different parts of the image. The basic idea is to represent an image as fixed points of Iterated Function Systems (IFS). Therefore, an input image can be represented by a series of IFS codes rather than pixels. In this way, an amazing compression ratio 10000:1 can be achieved. The application of fractal image compression presented in this paper is based on Spiral Architecture. Since there is no mature capture and display device for hexagon-based images, the experiments are implemented on a newly proposed mimic scheme, called Virtual Spiral Architecture (VSA). The experimental results in the paper have shown that introducing Spiral Architecture into fractal image compression will improve the compression performance in image quality with little trade-off in compression ratio. A lot of research work exists in this area to further improve the results. Copyright UNION Agency - Science Press.

Outlier detection is an important task in data mining because outliers can be either useful knowledge or noise. Many statistical methods have been applied to detect outliers, but they usually assume a given distribution of data and it is difficult to deal with high dimensional data. The Statistical Learning Theory (SLT) established by Vapnik et al. provides a new way to overcome these drawbacks. According to SLT Scholkopf et al. proposed a v-Support Vector Machine (v-SVM) and applied it to detect outliers. However, it is still difficult for data mining users to decide one key parameter in v-SVM. This paper proposes a new SVM method to detect outliers, SVM-OD, which can avoid this parameter. We provide the theoretical analysis based on SLT as well as experiments to verify the effectiveness of our method. Moreover, an experiment on synthetic data shows that SVM-OD can detect some local outliers near the cluster with some distribution while v-SVM cannot do that

Pseudolites, ground-based GPS signal transmitters, can significantly enhance the GPS satellite geometry or can even be an independent positioning system. However, as pseudolites are very close to the receivers, error effects are different from the traditional GPS and should be considered and modeled in a different way. Tropospheric delay is one of the largest error sources of pseudolite positioning, as pseudolite signal propagates through the lower troposphere which is very difficult to be modeled due to spatial variations in atmosphere. The objective of this research is to analyse pseudolite tropospheric delay modelling methods and to select the optimal tropospheric delay models for different applications. Several methods to estimate the tropospheric delay for pseudolite positioning are introduced and compared. One approach is to utilize single-differenced GPS tropospheric models. Another one is to compute the tropospheric delay as a function of the local refractivity along the pseudolite signal path. The ratio method used for Electronic Distance Measurement (EDM) can also be applied to estimate tropospheric delay. Experiments with simulation and real flight test data are conducted in this study to investigate the proposed methods. The advantages and limitations of each method are analysed. The mode defined by RTCA and its modification are suitable for a low elevation and short range application, such as LAAS and local ground based applications. Models derived from single-differenced NMF and Saastamoinen models perform well in long range and high elevation but have big bias in low elevation. And the model derived from the Hopfield model performs relatively well in all the range and elevation.

A resonator antenna made from a complex artificial surface and a metallic ground plane is described. The complex surface is realized using a woodpile electromagnetic bandgap (EBG) material, which is shown to have a frequency dependent reflection plane location. A highly directive radiation pattern is created due to the angle-dependent attenuation of the resonator antenna coupling to free space. The antenna has the advantages of low height, low loss, and low sidelobes. It is shown that the directivity can be varied over a fixed range by changing the aperture size of the device, with the maximum directivity determined by both the feed element and EBG material properties. The complete bandgap for the woodpile EBG material is confirmed from a band diagram, and its properties as a complex surface are investigated through transmission calculation and measurement. The design of the antenna is described, and two means of exciting the resonator, a microstrip patch and a double slot, are investigated. Theoretical results for these two antennas are calculated the using finite-difference time-domain and are shown to be in good agreement with measured results. © 2005 IEEE.

For each paint sample, the onset temperature for oxidation was reduced from 166°C to the range 50 to 60°C when a heating rate of 5 K min-1 was used. In order to determine the rate of drying, the non-isothermal experiments were carried out using a range of heating rates. A change in the mechanism oxidative polymerization was observed as the heating rate was increased. © 2005 Akadémiai Kiadó, Budapest.

An important feature in most urban roads and similar environments, such as in theme parks, campus sites, industrial estates, science parks, and the like, is the existence of pavements or curbs on either side defining the road boundaries. These curbs, which are mostly parallel to the road, can be harnessed to extract useful features of the road for implementing autonomous navigation or driver assistance systems. However, vision-alone methods for extraction of such curbs or road edge features with accurate depth information is a formidable task, as the curb is not conspicuous in the vision image and also requires the use of stereo images. Further, bad lighting, adverse weather conditions, nonlinear lens aberrations, or lens glare due to sun and other bright light sources can severely impair the road image quality and thus the operation of vision-alone methods. In this paper an alternative and novel approach involving the fusion of 2D laser range and monochrome vision image data is proposed to improve the robustness and reliability. Experimental results are presented to demonstrate the viability and effectiveness of the proposed methodology and its robustness to different road configurations and shadows.

Through cross-flow filtration (CFF) with a 1-kDa regenerated cellulose Pellicon 2 module, the ultrafiltration characteristics of river organic matter from Longford Stream, UK, were investigated. The concentration of organic carbon (OC) in the retentate in the Longford Stream samples increased substantially with the concentration factor (cf), reaching approximately 40 mg/L at cf 15. The results of dissolved organic carbon (DOC) and colloidal organic carbon (COC) analysis, tracking the isolation of colloids from river waters, show that 2 mg/L of COC was present in those samples and good OC mass balance (77-101%) was achieved. Fluorescence measurements were carried out for the investigation of retentate and permeate behaviour of coloured dissolved organic materials (CDOM). The concentrations of CDOM in both the retentate and permeate increased with increasing cf, although CDOM were significantly more concentrated in the retentate. The permeation model expressing the correlation between log[CDOM] in the permeate and logcf was able to describe the permeation behaviour of CDOM in the river water with regression coefficients (r2) of 0.94 and 0.98. Dry weight analysis indicated that the levels of organic colloidal particles were from 49 to 71%, and between 29 and 51% of colloidal particles present were inorganic. COC as a percentage of DOC was found to be 10-16% for Longford Stream samples. © 2005 Elsevier Inc. All rights reserved.

The (meta)logic underlying classical theory of computation is Boolean (two-valued) logic. Quantum logic was proposed by Birkhoff and von Neumann as a logic of quantum mechanics more than 60 years ago. It is currently understood as a logic whose truth values are taken from an orthomodular lattice. The major difference between Boolean logic and quantum logic is that the latter does not enjoy distributivity in general. The rapid development of quantum computation in recent years stimulates us to establish a theory of computation based on quantum logic. The present paper is the first step toward such a new theory and it focuses on the simplest models of computation, namely finite automata. We introduce the notion of orthomodular lattice-valued (quantum) automaton. Various properties of automata are carefully reexamined in the framework of quantum logic by employing an approach of semantic analysis. We define the class of regular languages accepted by orthomodular lattice-valued automata. The acceptance abilities of orthomodular lattice-valued nondeterministic automata and their various modifications (such as deterministic automata and automata with ε-moves) are compared. The closure properties of orthomodular lattice-valued regular languages are derived. The Kleene theorem about equivalence of regular expressions and finite automata is generalized into quantum logic. We also present a pumping lemma for orthomodular lattice-valued regular languages. It is found that the universal validity of many properties (for example, the Kleene theorem, the equivalence of deterministic and nondeterministic automata) of automata depend heavily upon the distributivity of the underlying logic. This indicates that these properties does not universally hold in the realm of quantum logic. On the other hand, we show that a local validity of them can be recovered by imposing a certain commutativity to the (atomic) statements about the automata under consideration. This reveals a...

The use of web log classification to identify the customer with a small data set is discussed. Web mining is a popular technique for analyzing visitor activities in e-service systems, which include, web text mining, web structure mining, and web log mining. Several groups of experiments on Dell Workstation PWS650 with 2 Gbytes of main memory running Window 2000 are conducted to evaluate the web log mining technique. The results show that when one classifies the 39,033 log records using the three classifiers, removing one attribute at a time, confirms that it's hard to determine which attribute to remove in order to achieve high accuracy.

We discuss the problem of designing unambiguous programmable discriminatorsfor any n unknown quantum states in an m-dimensional Hilbert space. Thediscriminator is a fixed measurement that has two kinds of input registers: theprogram registers and the data register. The quantum state in the data registeris what users want to identify, which is confirmed to be among the n states inprogram registers. The task of the discriminator is to tell the users whichstate stored in the program registers is equivalent to that in the dataregister. First, we give a necessary and sufficient condition for judging anunambiguous programmable discriminator. Then, if $m=n$, we present an optimalunambiguous programmable discriminator for them, in the sense of maximizing theworst-case probability of success. Finally, we propose a universal unambiguousprogrammable discriminator for arbitrary n quantum states.

Grinding is one of the most versatile methods of removing material from machine parts to provide precise geometry. Dynamic analysis of the grinding process is necessary to reduce the surface waviness and roughness induced by vibrations, and to offer a machining accuracy in the order of nanometers. This research is to investigate the dynamic function of the grinding process. A new approach to determination of cutting factors in dynamic grinding is proposed. Attention is paid to the mechanisms of dynamic grinding from the kinematics viewpoint. A non-linear dynamic model is developed to investigate the dynamic characteristics of the grinding process. The model demonstrates that different vibration frequencies result in qualitatively different behavior of the grinding machine. The relationship between grinding force variations and vibration frequency is revealed. The formulas to calculate cutting force variations are given. A comparison of the theoretical transfer function of dynamic grinding and experimental one shows good matching. As a result, the paper significantly expands the opportunities of vibration control of grinding machines. © 2004 Elsevier Ltd. All rights reserved.

Endocrine disrupting chemicals (EDCs) are the focus of current environment concern, as they can cause adverse health effects in an intact organism, or its progeny, subsequent to endocrine function. The paper reports on the removal of estrone (E1) and 17β-estradiol (E2) from water through the use of various adsorbents including granular activated carbon (GAC), chitin, chitosan, ion exchange resin and a carbonaceous adsorbent prepared from industrial waste. The results show that the kinetics of adsorption were adsorbent and compound-dependent, with equilibration being reached within 2 h for a waste-derived carbonaceous adsorbent to 71 h for an ion-exchange resin for E1, and within 7 h for the waste-derived carbonaceous adsorbent to 125 h for GAC for E2. Of all the adsorbents tested, the carbonaceous adsorbent showed the highest adsorption capacity, with a maximum adsorption constant of 87500 ml/g for E1 and 116000 ml/g for E2. The GAC also had a very high adsorption capacity for the two compounds, with a maximum adsorption constant of 9290 ml/g for E1 and 12200 ml/g for E2. The effects of some fundamental environmental parameters including adsorbent concentration, pH, salinity and the presence of humic acid and surfactant on adsorption were studied. The results show that adsorption capacity of activated carbon was decreased with an increase in adsorbent concentration and by the presence of surfactant and humic acid. The results have demonstrated excellent performance of a waste derived adsorbent in removing E1 and E2 from water, and indicated the potential of converting certain solid waste into useful adsorbents for pollution-control purposes. © 2005 Elsevier Ltd.

This paper presents a number of different route discovery strategies for on-demand routing protocols, which provide more control to each intermediate node make during the route discovery phase to make intelligent forwarding decisions. This is achieved through the idea of self-selection. In self-selecting route discovery each node independently makes route request (RREQ) forwarding decisions based upon a selection criterion or by satisfying certain conditions. The nodes which do not satisfy the selection criterion do not rebroadcast the routing packets. We implemented our self-selecting route discovery strategies over AODV using the GloMoSim network simulation package, and compared the performance with existing route discovery strategies used in AODV. Our simulation results show that a significant drop in the number of control packets can be achieved by giving each intermediate node more authority for self-selection during route discovery. Furthermore, a significant increase in throughput is achieved as the number nodes in the network is increased

Routing in Ad hoc Networks has received significant attention with a number of different routing protocols proposed in recent years. These routing protocols may be classified into three main categories: proactive, reactive and hybrid. Prior work aimed at comparing the performance of routing protocols has mainly focused on comparing reactive and proactive protocols [6] [4] [1]. In this paper, we present a simulation study of different routing protocols from all three categories. We also explore the benefits and performance of each routing category. Further, we present a discussion of future research directions for routing in Ad hoc Networks. © 2005 IEEE.

Quality is a key issue in the development of software products. Although the literature acknowledges the importance of the design phase of software lifecycle and the effects of the design process and intermediate products on the final product, little progress has been achieved in addressing the quality of designs. This is partly due to difficulties associated in defining quality attributes with precision and measurement of the many different types and styles of design products, as well as problems with assessing the methodologies utilized in the design process. In this research we report on an empirical investigation that we conducted to examine and evaluate quality attributes of design products created through a process of pair-design and solo-design. The process of pair-design methodology involves pair programming principles where two people work together and periodically switch between the roles of driver and navigator. The evaluation of the quality of design products was based on ISO/IEC 9126 standards. Our results show some mixed findings about the effects of pair work on the quality of design products. © 2005 IEEE.

The evolution of Australian Rainfall & Runoff is overviewed and the current on-going review is discussed. The inclusion of new information on the hydrology of rainfall and runoff for water quality investigations in both urban and rural areas, the use of catchment simulation techniques, the integration of hydrologic and hydraulic models, and hydrological aspects of integrated water management within urban areas is overviewed.

Urban stormwater runoff is a transport medium for many contaminants from anthropogenic sources. There are many alternative management strategies available to treat these contaminants. One of the technologies suggested for this purpose is the use of permeable pavements to minimise the quantity of surface runoff generated by impervious surfaces within an urban catchment. Reported herein are the results of a monitoring program undertaken to assess the effectiveness of permeable pavers for reducing the quantity and quality of stormwater runoff. It was found that the catchment where a Rocla Ecoloc paver was installed had the effective imperviousness reduced from 45% prior to reconstruction of the road surface with the permeable pavers to less than 5% after reconstruction of the road. At the same time, the quality of the surface runoff was found to be at the lower levels of runoff from road surfaces while no increase in stormwater contaminants within the groundwater system was monitored.

Method engineering, which focuses on project-specific methodology construction from existing method fragments, is an appealing approach to organize, appropriately access and effectively harness the software engineering knowledge of MAS methodologies. With the objective of applying method engineering for developing an MAS, in this paper we introduce a generic metamodel to serve as a representational infrastructure to unify existing MAS methodologies into a single specification. Our metamodel does not focus on any class of MAS, nor does it impose any restrictions on the format of the system requirements; rather, our metamodel is an abstraction of how any MAS is structured and behaves both at design time and run-time.

New Multi-Agent System (MAS) software development methodologies are published at an increasing pace. This is in part due to the accepted premise that no single methodology can be suitable for all MAS software projects. Method engineering, which focuses on projectspecific methodology construction from existing method fragments, is an appealing approach to organize, appropriately access and effectively harness the software engineering knowledge of methodologies. Towards this, in this paper we present and validate a generic productfocussed metamodel to serve as a representational infrastructure to unify existing methodologies into a single specification. Our metamodel does not focus on any class of MAS, nor does it impose any restrictions on the format of system requirements; rather, our metamodel is an abstraction of how any MAS is structured and behaves both at design time and run-time. We analyze two well-known existing MAS metamodels. We sketch how they can be seen as subtypes of our generic metamodel. This constitutes early evidence to support the use of our metamodel towards the construction of situated MAS methodologies.

The influence of ontologies in Knowledge Based Systems (KBS) methodologies extends well beyond the initial analysis phase, leading in the 1990s to domain-independent KBS methodologies. In this paper, we reflect on those lessons and on the roles of ontologies in KBS development. We analyse and identify which of those roles can be transferred towards an ontology-based MAS development methodology. We identify ontology-related inter-dependencies between the analysis and design phases. We produce a set of six recommendations towards creating a domain-independent MAS methodology that incorporates ontologies beyond its initial analysis phase. We identify its essential features and sketch the characteristic tasks within both its analysis and design phases.

A common approach for the assessment offlood risk associated with a proposed development in a flood-prone area is the utilisation of a catchment modelling system. Numerous alternative hydrologic and hydraulic process models have been proposed for inclusion in these systems of process models. In a similar vein, a number of alternative rainfall models for the description of the spatial and temporal variation ofrainfall have been proposed. Previous studies such as those by Walsh et al. (1991) and Hill et al. (1996) have shown the importance ofthe loss model, or the model by which water is removed from rainfall to produce potential surface runoff. While previous studies have indicated the importance ofloss models in the estimation of a design flood flow with a pre-defined annual exceedance probability, little information has been developed to assist modellers with the task ofconverting rainfall ofa given annual exceedance probability into flow with the same exceedance probability through the application of catchment modelling systems.

It has been suggested that constraining a natural language (NL) reduces the degree of ambiguity of requirement specifications written in that language. There is also a tendency to assume that an inescapable side effect of constraining a natural language is a subsequent reduction in its expressiveness. The primary objective of this paper is to describe a technique that we have developed for empirically measuring the expressiveness of a Constrained Natural Language (CNL) when used to specify the requirements in a particular application domain. Our simple yet practical and repeatable technique elucidates the individual contribution that each lexical entity of the CNL can make on the overall expressiveness of the CNL. This technique is particularly useful for designing new CNLs, as well as situations where tailoring or streamlining existing CNLs for particular application domains is needed.

Generally, they are often not really interesting to constraint-based real business, hi order to work out patterns that are of interest and actionable to the real world, in-depth patterns are often essential. This type of pattern discovery is more likely to be a business or industry domain-driven human-machine-cooperated process. The use of in-depth patterns requires the development of a more practical methodology, than is presently available for guiding real-world data mining. This paper proposes such a practical data mining methodology, referred to as domain-driven in-depth pattern discovery (DDID-PD). The main idea of the DDID-PD methodology is to mine in-depth patterns through domain-driven iterative human-machine interaction in a constraint-based context. Using this methodology as a basis, we demonstrate some of our work in mining in-depth correlations in Australian Stock Exchange (ASX) data and preliminary research on developing a quality knowledge base for Centrelink interventions. The deployment of DDID-PD to ASX data mining tasks has shown that the methodology is practical and has potential for further improving the analysis of large quantities of data to identify patterns for practical use by industry and business. © 2013.

Early requirements analysis (ERA) is quite significant for building agent-based systems. Goal-oriented requirements analysis is promising for the agent-oriented early requirements analysis. In general, either visual modeling or formal specifications is used for the ERA. This way cannot capture requirements precisely and completely. In this paper, we present an integrative modeling framework for agent-oriented early requirements analysis; this framework implements goal-oriented requirement analysis. The integrative modeling combines visual modeling and formal modeling together. Extended i* framework is used for building visual models; formal specifications complement the visual modeling to define and refine requirements. Both visual and formal models are outlined through a practical agent-based system F-TRADE1. The integrative modelling seems to model early requirements comprehensively and concretely, and benefit refinement and conflict management in building agent systems. © 2005 IEEE.

Dynamic environments such as that of any public and private infrastructure, workplace and even home consist of multiple entities that continuously interact with each other. Integrating an intelligent security system in such an environment necessitates the need for a soft systems approach that gives perspective to such interactions through identifying associated holons. The holonic analysis allows characterisation of ill-defined and often problematic situations that are resultant of the human activity system. This paper discusses some techniques that can be adopted to resolve scenarios that are plagued with uncertainty in reasoning and the continuously varying nature of interrelationship between native entities. The technical aspect of this system encompasses the mode of query processing and surveillance through a structured sensor network set up with the aid of distributed services and network protocols.

Use of Telecollaboration (TC) systems based on sensor networks in education is an emerging field of research. It is feasible to connect many small wireless micro-sensors ("smart dust") [36], PDAs and cellular phones into a network that extends a TC education system. It is expected that those sensors collect and fuse various data and transmit the information through the network for enhanced TC educational outcomes. However, the traditional challenges remain the same. This includes the ability of managing resources such as: power, bandwidth, distances, performance of the sensors and related hardware. At the heart of the sensor network paradigm are the human factors. We realize that the concept of the human research is native to such emerging technologies as Wireless Sensor Networks, sensor enabling facilities, ubiquitous computing devices and all IP next generation networks that are challenging the rationale of traditional information fusion systems. The technology has reached a level of maturity at which it is reasonable to discover sensors based on the context awareness, pertinence, query for appropriate data, and fuse it using applicable fusion rules, computing and communication infrastructure. In this paper we introduce innovative concepts for support of TC solutions, identify design, development methodologies as well as challenges for TC systems. © 2005 IEEE.

The internationalization and virtualization of both educational institutes and workplaces around the world is driving the development of technology that supports remote collaboration. Telecollaboration is aimed at bringing participants together into a virtual co-location where these participants can collaborate with each other. Over 2003 and 2004, several groups of students from the University of Technology, Sydney attempted to modify an existing conferencing package. This resulted in the development of a prototype telecollaboration system. In this paper we re-evaluate the architecture of the prototype, making a number of observations about the system and giving rise to a list of key features for a middleware that is capable of masking the heterogeneity of telecollaborative services and also provides for pervasive and ambient access to resources and services throughout such systems. © 2005 IEEE.

Electrical market often demands accurate forecasting of electrical load for planning and operation of the power infrastructure. Current models can forecast load from half hour up to 24 hours and are based on aggregate temperature for the entire day. Although these models work very well, they do not consider the intermediate real time information between time intervals to forecast load which introduce many uncertainties pertaining to factors such as climatic conditions, geographic locations etc. Furthermore, such intermediate real time information is costly and difficult to obtain. With the aid of distributed sensor networks, real time information can easily be obtained which can lead to precise planning and operation of power systems. Such information can easily improve electrical load forecasting and reduce uncertainty which can have a direct impact on the customer. We propose new and improved models for electricity load forecasting by incorporating real-time weather (temperature) information arising from the low-cost distributed sensor networks.

Traditionally, Information Fusion systems assume that the information is gathered from known sensors over proprietary communication networks and fuse using fixed rules of information fusion and designated computing and communication resources. Emerging technologies like wireless sensor networks, TEDS enabled legacy sensors, ubiquitous computing devices and all IP next generation networks are challenging the rationale of conventional information fusion systems. The technology has matured to a point where it is reasonable to discover sensors based on the context, establish relevance, query for appropriate data, and fuse it using the most appropriate fusion rule, using ubiquitous computing and communication environment in an opportunistic manner. We define such fusion systems as opportunistic information fusion systems. In this paper we introduce this new paradigm for information fusion and identify plausible approaches and challenges to design, develop and deploy the proposed next generation opportunistic information fusion systems.

Multi-hop Ad-hoc Network is promising to extend the reach of current Mobile Internet, and support ubiquitous computing. However, it is hindered by the lack of a flexible network structure bridging the gaps between MANETs and heterogeneous IP networks. This paper introduces a novel Mobile Peer-to-Peer Overlay as an enabling structure for uniting connectivity, mobility and services. Our proposed service architecture allows mobile users to build networks on-the-fly, and capitalize relevant resources in their vicinity for universal communications. Practical implementation of system prototype demonstrates that our proposed framework lays a solid foundation for developing an Integrated Mobile Internet and Ubiquitous Computing. © 2005 IEEE.

Trust and trustworthiness plays a major role in conducting business on the Internet in service-oriented environments. In defining trust for service-oriented environments, one needs to capture the notation of service level, service agreement, context and timeslots. The same applies for reputation which is the opinion of the third party agents which is used in determining the trust and trustworthiness. Because of the complexity of the issues, and the fact that the trust and reputation are essentially concerns with the relationships, it is important to clearly define the notion of the trust relationships and notion of the reputation relationships. In this paper, therefore, we clear these definitions and we introduce a graphical notation for representing these relationships.

The growing development in web-based trust and reputation systems in the 21st century will have powerful social and economic impact on all business entities, and will make transparent quality assessment and customer assurance realities in the distributed web-based service oriented environments. The growth in web-based trust and reputation systems will be the foundation for web intelligence in the future. Trust and Reputation systems help capture business intelligence through establishing customer relationships, learning consumer behaviour, capturing market reaction on products and services, disseminating customer feedback, buyers opinions and end-user recommendations, and revealing dishonest services, unfair trading, biased assessment, discriminatory actions, fraudulent behaviours, and un-true advertising. The continuing development of these technologies will help in the improvement of professional business behaviour, sales, reputation of sellers, providers, products and services. In this paper, we present a new methodology known as CCCI (Correlation, Commitment, Clarity, and Influence) for trustworthiness measure that is used in the Trust and Reputation System. The methodology is based on determining the correlation between the originally committed services and the services actually delivered by a Trusted Agent in a business interaction over the service oriented networks to determine the trustworthiness of the Trusted Agent.

The growing development of web-based reputation systems in the 21st century will have a powerful social and economic impact on both business entities and individual customers, because it makes transparent quality assessment on products and services to achieve customer assurance in the distributed web-based Reputation Systems. The web-based reputation systems will be the foundation for web intelligence in the future. Trust and Reputation help capture business intelligence through establishing customer trust relationships, learning consumer behavior, capturing market reaction on products and services, disseminating customer feedback, buyers opinions and end-user recommendations. It also reveals dishonest services, unfair trading, biased assessment, discriminatory actions, fraudulent behaviors, and un-true advertising. The continuing development of these technologies will help in the improvement of professional business behavior, sales, reputation of sellers, providers, products and services. Given the importance of reputation in this paper, we propose ontology for reputation. In the business world we can consider the reputation of a product or the reputation of a service or the reputation of an agent. In this paper we propose ontology for these entities that can help us unravel the components and conceptualize the components of reputation of each of the entities.

Traditionally, transactions were carried out face-toface, now, they are carried out over the Internet. The infrastructure for the above business and information exchange could be client-server, peer-to-peer or mobile network environments, and very often users on the network carry out interactions in one of three forms: • Anonymous (No names are identified in the communication) • Pseudo-anonymous (Nicknames are used in the communication) • Non-anonymous (Real names are used in the communication) Incapability or a fraudulent practice could occur when the seller or business provider or buyer (the agents on the network) does not behave in the manner that is mutually agreed or understood, especially if published terms and conditions exist. This paper evaluates currently existing trustworthiness systems and points out that currently there is no existing standardized measurement system for Quality of Service and outlines the methodology that we have developed for this.

In this paper, we propose and describe the six characteristics of trust. Based on the six proposed characteristics, we determine why trust is fuzzy. The term 'fuzzy' in this paper not in the sense of the precise definitions given in the Fuzzy Systems literature but to indicate a certain vagueness, complexity or ill-definition and qualitative characterization rather than quantitative representation and dynamic.We then determine why due to the six characteristics of trust, trust is dynamic. We then propose a modeling language tool to model the fuzzy and dynamic nature of trust.

Operators of traffic control rooms are often required to quickly respond to critical incidents using a complex array of multiple keyboards, mice, very large screen monitors and other peripheral equipment. To support the aim of finding more natural interfaces for this challenging application, this paper presents PEMMI (Perceptually Effective Multimodal Interface), a transport management system control prototype taking video-based manual gesture and speech recognition as inputs. A specific theme within this research is determining the optimum strategy for gesture input in terms of both single-point input selection and suitable multimodal feedback for selection. It has been found that users tend to prefer larger selection areas for targets in gesture interfaces, and tend to select within 44% of this selection radius. The minimum effective size for targets when using 'device-free' gesture interfaces was found to be 80 pixels (on a 1280×1024 screen). This paper also shows that feedback on gesture input via large screens is enhanced by the use of both audio and visual cues to guide the user's multimodal input, Audio feedback in particular was found to improve user response time by an average of 20% over existing gesture selection strategies for multimodal tasks.

In this paper, an Adaptive Median Constant False Alarm Rate (AMCFAR) and multi-frame post detection integration algorithm is proposed for effective real time automatic target detection of boat-generated acoustic signals, in which, an observation space is created by sampling and dividing input analog acoustic signal into multiple frames and each frame is transformed into the frequency domain. In the created observation space, a Median Constant False Alarm Rate (MCFAR) and post detection integration algorithms have been proposed for an effective automatic target detection of boat generated acoustic signals, in which a low constant false alarm rate is kept with relative high detection rate. The proposed algorithm has been tested on several real acoustic signals from hydrophone sensors, and statistical analysis and experimental results showed it able to provide a very low false alarm rate and a relatively high detection rate in all cases.

In this paper, a Recurrent Compensatory Neuro-Fuzzy System (RCNFS) is proposed for identification and prediction. The compensatory-based fuzzy reasoning method is using adaptive fuzzy operations of neuro-fuzzy systems that can make the fuzzy logic systems more adaptive and effective. The recurrent network is embedded in the RCNFS by adding feedback connections in the second layer, where the feedback units act as memory elements. Also, an on-line learning algorithm is proposed to automatically construct the RCNFS. They are created and adapted as on-line learning proceeds via simultaneous structure and parameter learning. Finally, the RCNFS is applied in several simulations. The simulation results of the dynamic system modeling have shown that 1) the RCNFS model converges quickly; 2) the RCNFS model requires a small number of tuning parameters; 3) the RCNFS model can solve the temporal problems and approximate a dynamic system.

Autonomie Communications have attracted huge attention recently for the management of telecommunication networks in the European Network Research Community. The purpose of this research is to offer the abilities such as autonomy, scalability, adaptation as well as simplicity for management application in complex networks. The accomplished networks inspired by biological mechanisms or market-based concepts could enable agents to be of intelligence, scalablility, and interoperabliliry in the management functional domains with regards to the large volume requirements from services' fulfillment perspective in decentralized Multi-Agent Systems. In accordance with TMF and FIPA specifications and requirements, the autonomy attributes self-configuring, self-adapting, self-limiting, self-preserving, and self-optimizing are involved into our simulation. Resource allocation requests are bidded for a long session in the multi-unit Vickrey-Clarke-Groves auction. This design adopts the software development methodology-GAIA and the framework-JADEx. We have shown multiple service configuration in dynamic network can be nearly optimized by autonomie behaviors via bidding according to business objectives for getting maximum revenues. We conclude this end-to-end approach maintains self-managing capability, easy-to-implement scalability, and more incentively compatible and efficient over other common implementation so that it could achieve the optimal solution to the flexible requirements for the Service Fulfillment for advanced IP networks. © 2005 IEEE.

In this paper, Cellular Neural Networks (CNNs) for Hexagonal Image Processing (HIP) frameworks has been proposed. In this paper, we combine two distinguished researches; one is CNNs, which provide efficient computing abilities. The other is HIP, which contains most compact structure. Both CNNs and HIP are inspired by biological. CNNs present the behaviors which are most similar to the retina of human's eyes, and HIP presents architecture which is also most similar to the distribution of cells on the retina.

This paper investigates a novel biological visual processing for hybrid-order texture boundary detection. The texture boundary detection is based on the first- and second-order features to model the pre-attentive stage of a human visual system. This system is implemented by a cellular neural network universal machine (CNN-UM) with 3×3 templates to approximate desired filter transfer functions. The system design can process a 64×64 gray-scale image. The proposed algorithm can successfully be performed by CNN-UM and detect the texture boundary in a given image.

In this study, a computational model for chromatic texture segregation is developed. The model attempts to simulate the visual processing characteristics by mimicking the visual perception. According to Hering's opponent theory, we deal with color information in a color space with three opponent axes. The algorithm extracts 1st-order features by a Gaussian filter and 2 nd-order features by a set of Gabor filters as so called Gabor wavelets. The hybrid-order features are combined at a common site to detect the boundary. The model is very intuitive and physiological relevant such that it reserves opportunities for further approaches.

This paper presents part of the ongoing experimental and analytical work to investigate the effect of corbels on continuity in timber bridges. Full scale beams with corbels were erected for testing the extreme boundary conditions such as simply supported and fixed end conditions. The states of continuity in the test beams were assessed through a three span beam loading test set up. Dynamic tests were performed on the test beams and the modal parameters extracted were compared against those obtained for simply supported beams without corbel. Analytical investigations were conducted and then compared with the experimental results. The static experimental results obtained showed changes in the vertical displacement for different boundary conditions. The magnitude of reduction in the measured vertical displacement was fairly sensitive to the change of boundary conditions. Hence, changes in vertical displacement at mid-span can be used as an indicator for different boundary conditions, which relate to the effect of corbel on both continuity and effective span length in a structural system, especially for timber bridges. A comparative analysis of the first natural frequency for each boundary condition was then undertaken with reference to a simply supported benchmark. The analysis confirmed that the effects of changes in the boundary can be detected using modal parameters. © Institute of Materials Engineering Australasia Ltd 2005.

Most existing recommender systems employ collaborative filtering (CF) techniques in making projections about which items an e- service user is likely to be interested in, i.e. they identify correlations between users and recommend items which similar users have liked in the past. Traditional CF techniques, however, have difficulties when confronted with sparse rating data, and cannot cope at all with time-specific items, like events, which typically receive their ratings only after they have finished. Content-based (CB) algorithms, which consider the internal structure of items and recommend items similar to those a user liked in the past can partly make up for that drawback, but the collaborative feature is totally lost on them. In this paper, modelling user and item similarities as fuzzy relations, which allow to flexibly reflect the graded/uncertain information in the domain, we develop a novel, hybrid CF-CB approach whose rationale is concisely summed up as 'recommending future items if they are similar to past ones that similar users have liked', and which surpasses related work in the same spirit.

Despite its critical importance to the process of systems development, requirements elicitation continues to be a major problem in both research and practice. This complex activity involving many different facets and issues is often performed badly and subsequently blamed for project failure and poor quality systems. In this paper we present a collaborative and combinational approach to requirements elicitation within a systems engineering framework, proposing the application of current research from other disciplines in areas related to requirements elicitation, such as software engineering and the social sciences, to a general systems engineering context. The work provides both researchers and practitioners with an approach to requirements elicitation for systems engineering that can be applied to real world projects to improve both the process and results, thereby increasing the overall chance of successful system development in terms of on schedule and on budget delivery, and satisfied customers.

Loss of mobility can occur for a variety of reasons,such as spinal cord injury or motor neurone disease. The onset of these conditions often brings with it an associated loss of personal independence, which is primarily due to the fact that the sufferer is no longer able to control their mobility. This project aims to address this problem through the creation of a head movement based wheelchair control system. Using a personal digital assistant (PDA) artificial intelligence techniques on an embedded LINUX operating system, a wireless head movement wheelchair control system has been designed and implemented. This system provides relief for sufferers of conditions which inhibit mobility through a method of wheelchair control which offers enhanced ease of use, attractiveness and independence. © 2005 IEEE.

The aim of this research study is to evaluate the availability and classification of the types of currently available Internet self-help for depression. Its aim is to develop an understanding of what is available for young people at risk of depression who would otherwise perhaps not seek help. In Australia, depression is the top-ranked cause of nonfatal disability. Over 27% of young adults have a current mental disorder, with depression being the most prevalent (10.8%). Though there are Internet-based self-help programs, evidence-based interactive programs developed specifically for young people, are not yet available. Recommendations are also made for further research. © 2005.

XML is a popular approach to interoperable exchange of data between a wide range of devices. This paper explores the use of the Remote XML Exchange Protocol as a mechanism to provide efficient interaction with complex XML documents to users with limited complexity devices and/or limited bandwidth connections. The interactive mechanisms provided by the protocol allow users to navigate, edit and download XML even when delivery of the full XML document is impossible. The paper examines the use of the protocol to enable multiple users to collaboratively edit remote XML documents. Further, the paper explores the combination of the protocol, collaborative editing and recently released Word processor/Office suite XML schema formats.

This paper proposes to integrate security parameters into the Service Level Specification (SLS). Integrating those parameters in the QoS part of the Service Level Agreement (SLA) specification is essential in particular for secure multimedia services since the QoS is negotiated when the multimedia service is deployed. Security mechanisms need to be negotiated at that time when sensible multimedia information is exchanged. In this paper we show that including security parameters in the SLA specification improves the negotiation, deployment and use of the secure multimedia service. The parameters this paper proposes to integrate have the advantage to be understandable by both the end-users and service providers.

The enterprise computer-based systems employed by the organisations of today can be extremely complex. Not only do they consist of countless hardware and software products from many varied sources, but they often span continents, piggybacking on public networks. These systems are essential for undertaking business and general operations in the modern environment, and yet the ability of organisations to control their evolution is questionable. The emerging practice of enterprise architecture seeks to control that complexity through the use of a holistic and top-down perspective. However, the toolsets already in me, are very much bottom-up by nature. To overcome the limitations of current enterprise architecture practices, the authors propose the use of the ABACUS methodology and toolset. The authors conclude that by using ABACUS to analyse software and enterprise systems, architects can guide the design and evolution of architectures based on quantifiable non-functional requirements. Furthermore, hierarchical 3D visualisation provides a meaningful and intuitive means for conceiving and communicating complex architectures.

The main contribution of this paper is an algorithm for integrating motion planning and simultaneous localisation and mapping (SLAM). Accuracy of the maps and the robot locations computed using SLAM is strongly dependent on the characteristics of the environment, for example feature density, as well as the speed and direction of motion of the robot. Appropriate control of the robot motion is particularly important in bearing-only SLAM, where the information from a moving sensor is essential. In this paper a near minimum time path planning algorithm with a finite planning horizon is proposed for bearing-only SLAM. The objective of the algorithm is to achieve a predefined mapping precision while maintaining acceptable vehicle location uncertainty in the minimum time. Simulation results have shown the effectiveness of the proposed method. © 2005 IEEE.

Musicians in training need to understand the sound they are producing in order to improve its deficient aspects. Verbal feedback from musical masters is the usual method used for attaining this understanding. However, using real-time sound visualisation as a complementary form of feedback, allows the large amounts of data typical of real-time acoustic analysis to be employed within training. This improves the efficiency of the feedback loop normally present within musical training and pedagogy. The implementation and effect of such a system is discussed. © 2005 IEEE.

With the wide acceptance of Web Services as the preferred implementation platform for service-oriented applications there is increased interest in how such applications should be designed, While there are similarities between software components and services there is now a general agreement that mapping existing components directly to Web Services leads to suboptimal design and results in poor performance and scalability. Most practitioners recommend the use of coarse-grained, message-oriented Web Service that minimize the number of messages and avoid the need to maintain state information between invocations. We argue that the design of message structures used as Web Services payloads directly impacts on application interoperability, and that excessive use of coarse-grained, document-centric message structures results in poor reuse and undesirable interdependencies between services. Our approach provides a framework for the design message structures using data engineering principles. We consider the impact of increasing message granularity on cohesion and coupling of service-oriented applications and analyze associated design trade-offs. © Springer-Verlag Berlin Heidelberg 2005.

The emergence of Web services represents a shift from componentbased architectures that have proved successful in the context of enterprise computing to service-oriented architectures that are more suited to the highly distributed Internet-based applications. This trend towards service-oriented computing necessitates the re-evaluation of software development methodologies that are used in the construction of distributed applications. With growing acceptance of service-oriented computing and increasing number of large-scale Web Services projects there is some evidence that practitioners involved in implementing these solutions are paying only limited attention to how such applications should be designed. Frequently, the design of Web Services applications is driven by performance and scalability considerations, rather than any sound software engineering principles. A comprehensive methodological framework is required to guide designers and developers of service-oriented applications through the various phases of software development life cycle with specific emphasis on producing stable, reusable and extendable services. In this paper we discuss design of service-oriented applications from a software engineering perspective, and propose a software development framework for Web Services based on identification of elementary business function using business function decomposition and mapping these functions to service operations. We apply interface design principles adapted from object-oriented design as guidelines for the design of services.

Application Service Providing (ASP) emerged towards the end of 90s with claims of extensive advantages for client organizations, in particular for small and medium size enterprises (SMEs). Notwithstanding many perceived advantages the ASP approach has not gained wide acceptance as the new model for delivery of enterprise applications. Many of the early ASP providers have not been able to establish a viable business model and have discontinued ASP services, or went out of business altogether. However, some major ICT vendors have recently re-confirmed their commitment to the application-as-service model and made large investments in Utility Computing infrastructure. What are the long-term prospects for application servicing? Is Utility Computing a new paradigm for the delivery of enterprise applications, or is this yet another ICT industry fad? How should user organizations respond to these developments? This paper follows on from earlier work of the authors [Feuerlicht, Vorisek, 2002], [Feuerlicht, Vorisek, 2003], and gives a detailed description of the ASP approach. We then summarize both technological and business prerequisites for successful application servicing. We argue that the application-as-service model constitutes a viable alternative to software licensing for many application types today, and will become the dominant method for delivery of enterprise applications in not too distant future. End user organizations need to prepare now for this shift from licensed software and in-house implementation towards applications delivered as services, so that they are able to take full advantage of this new trend.

An anatomically based, multi-body model of the C5/C6 motion segment was developed to study soft-tissue neck injury mechanisms in rear impacts. This was integrated into the MADYMO-based van der Horst head and neck model. Responses were compared with volunteer test data up to head restraint impact. Soft-tissue loading was predicted for a series of rear-end vehicle crashes with crash recorders (n=78) and known long-term pain outcomes. Facet capsule shear and impingement injury mechanisms at C5/C6 were demonstrated. Facet capsule loading correlated well with NIC max and was able to predict the risk of AIS1 neck injuries with persisting pain.

Face and body movements are captured simultaneously using two separate cameras. For each face and body image sequence single expressive frames are selected manually for analysis and recognition of emotions. Firstly, individual classifiers are trained from individual modalities for mono-modal emotion recognition. Secondly, we fuse facial expression and affective body gesture information at the feature and at the decision-level. In the experiments performed, the emotion classification using the two modalities achieved a better recognition accuracy outperforming the classification using the individual facial modality. We further extend the affect analysis into a whole image sequence by a multi-frame post integration approach over the single frame recognition results. In our experiments, the post integration based on the fusion of face and body has shown to be more accurate than the post integration based on the facial modality only.

This paper presents an approach to automatic visual emotion recognition from two modalities: face and body. Firstly, individual classifiers are trained from individual modalities. Secondly, we fuse facial expression and affective body gesture information first at a feature-level, in which the data from both modalities are combined before classification, and later at a decision-level, in which we integrate the outputs of the monomodal systems by the use of suitable criteria. We then evaluate these two fusion approaches, in terms of performance over monomodal emotion recognition based on facial expression modality only. In the experiments performed the emotion classification using the two modalities achieved a better recognition accuracy outperforming the classification using the individual facial modality. Moreover, fusion at the feature-level proved better recognition than fusion at the decision-level.

Abstract The optimal treatment of patients with childhood acute lymphoblastic leukaemia (ALL) depends on establishing accurate diagnosis. Our investigations seek to strategically develop the application of microarray gene expression profiling to identify ALL patients with clinically homogenous presentations but which may respond differently to established treatment regimens. We have determined the gene expression profiles of ALL bone marrow (BM) samples taken from patients at diagnosis. Data analysis has focussed on the use of a novel and innovative statistical technology, Gene-RaVE. This series of patent protected algorithms builds a multinomial regression model using Bayesian variable selection. Gene-RaVE leads to the generation of a parsimonious and simple diagnostic gene expression signature, but which provides increased predictive ability over current analysis approaches. We describe our analysis of both Affymetrix (HU133A) and cDNA (10.5K) microarray gene expression profiles generated from diagnostic BM from >100 ALL patients covering the broad ALL subtypes including T and B lineage as well as T cell lymphoma leukaemia. Comparison of gene expression data failed to identify clearly distinguishing profiles between patients identified as ‘standard risk’ from ‘medium risk’ according to BFM95 clinical criteria. Gene expression profiles from a cohort of ALL patients, identified as ‘standard risk’ at diagnosis, were compared on the basis of their overall clinical outcome: relapse within 2 yrs vs non-relapse. Using a range of analyses including t-test, Gene-RaVE, discriminant analysis approaches and principle component analysis, we have discovered that small subsets of genes (<10), all of which included Nedd4BP3 and Ribosomal Protein L38 (RPL38), can be used to distinguish the two outcome groups. Subsequent validation using real time PCR supports the increase in Nedd4BP3 expression in standard risk pat...

View description>>
In this study, the need of pretreatment of flocculation and adsorption on flux improvement was evaluated in terms of critical flux. Critical flux is defined as the maximum filtration rate, under which the membrane fouling does not occur during operation. The critical flux was experimentally evaluated for crossflow microfiltration (CFMF) with and without the pretreatment using biologically treated sewage effluent from a Sewage Treatment Plant in South Korea. The results indicate that the preflocculation could not enhance significantly the critical flux. However, the preadsorption led to a critical flux of more than 3 times higher than that of wastewater (200 L/m2.h). When both flocculation and adsorption were used as pretreatment, the critical flux was raised up to 1000 L/m2.h. Molecular weight distribution (MWD) analyses on the wastewater before and after pretreatment indicated that flocculation-adsorption as pretreatment was efficient to remove most of organic matter in this wastewater, which contains small and middle range MW molecules (250â780 Daltons). The Scanning Electron microscope (SEM) showed that membrane fouling during the critical flux experiments was mainly due to pore blocking and small particles deposit on the membrane surface.

Many E-commerce websites attempt to develop personalized features to encourage users' repetitive visits. Yet, there is less attention about the applications of personalization technologies in E-government services. In this study, we present a classification of personalization techniques. Also, a novel recommendation approach is proposed to improve the existing techniques by the integration of user-based and item-based collaborative filtering recommendation techniques. A recommender system prototype, named Smart Trade Exhibitions Finder, is developed to help companies choosing the right trade exhibitions.

Many mechanisms have been developed to deliver only relevant information to the web users and prevent information overload. The most popular recent developments in the e-commerce domain are the user-preference based personalization and recommendation techniques. However, the existing techniques have a major drawback - poor accuracy of recommendation on one-and-only items - because most of them do not understand the item's semantic features and attributes. Thus, in this study, we propose a novel Semantic Product Relevance model and its attendant personalized recommendation approach to assist Export business selecting the right international trade exhibitions for market promotion. A recommender system, called Smart Trade Exhibition Finder (STEF), is developed to tailor the relevant trade exhibition information to each particular business user. STEF reduces significantly the time, cost and risk faced by exporters in selecting, entering and developing international markets. In particular, the proposed model can be used to overcome the drawback of existing recommendation techniques. © Springer-Verlag Berlin Heidelberg 2005.

Recommender systems have gained successfully applications for the past ten years, particular in E-commerce domain. However, existing recommendation approaches can not effectively deal with recommendation issue of one-and-only items occurred in government-to-business services, e.g. recommendation of trade exhibitions. Thus, in this study, we propose a novel approach by integrating semantic information with the traditional item-based collaborative filtering, and attempt to help the businesses choose the right trade exhibitions at the right time. The outcome of this study will have tremendous significance in overcoming the new item problem of existing recommendation approaches.

This paper proposes a new economic load dispatch model that considers cost coefficients with uncertainties and the constraints of ramp rate. The uncertainties are represented by fuzzy numbers, and the model is known as fuzzy dynamic economic load dispatch model (FDELD). A novel hybrid genetic algorithm with quasi-simplex techniques is proposed to handle the FDELD problem. The algorithm creates offspring by using generic operation and quasi-simplex techniques in parallel. The quasi-simplex techniques consider two potential optimal search directions in generating prospective offspring. One direction is the worst-opposite direction, which is used in the conventional simplex techniques, and the other is the best-forward direction, which is a ray from the centroid of a polyhedron whose vertexes are all the points but the best one towards the best point of the simplex. In addition, in order to reserve more fuzzy information, the fuzzy number ranking method is used to optimize the cost function, avoiding the lost some useful information by getting /spl lambda/-level set. The experimental study shows that FDELD is more practical model; the algorithm and techniques proposed are very efficient to solve FDELD problem.

In this paper, we investigate the problem of inter-robot collision avoidance in multiple mobile robot formation control. Two methodologies are utilized, namely Virtual Robot tracking by [Jongusuk and Mita, 2001] and l-l control by [Desai et al., 1998] to establish formation and avoid collision among robots. We point out that the framework in Virtual Robot tracking is potentially subject to collision among robots. This drawback is overcome in our design by incorporating a different reactive scheme in the incident possibility of collision. To prove the advantages of our framework, we demonstrate in simulation the case of three robots moving in formation and avoiding inter-robot collisions.

One of the major weaknesses of existing peer-to-peer (P2P) networks is that their overlay structures do not correlate to the physical underlying network topology. As a result, the overlays waste network resources and introduce excessive end-to-end latency for P2P applications. In this paper, we present a new model for topology-aware overlay formation. Firstly, it clusters nodes that are close to each other in terms of network latency and network membership. Secondly, it discovers the underlying topology between clusters to form an efficient overlay. The model is self-organising and distributed without the need of global knowledge.

Expanding the Internet infrastructure to span mobile devices is a challenging task. The Internet's addressing and routing scheme was originally designed for fixed devices making it inoperable without redirection and tracking functions such as those proposed by Mobile IP. However, Mobile IP requires prior network setup, and causes a large added overhead. In this paper, we propose a new approach to support mobile IP users using a Peer-to-Peer overlay network. The proposed overlay exploits locality to efficiently use the network resources and manage location data in a self-organizing and distributed fashion. The simulation results are presented. © 2005 IEEE.

IT was supposed to lead to the paperless office. However it has actually caused paper usage levels to increase. There are several social explanations for this increasing trend. Printing technology has become more available, and people have more information to print. In addition people often prefer printed matter to working off a screen. In this article we present a case study of paper usage at a University. It was found that, despite continual pressures escalating paper use, a range of strategies from quotas and charges, doublesided printing, reuse of scrap paper and policy changes had been successful in reducing usage. Motivational factors included cost saving and a commitment to the environment.

This paper identifies an approach for designing software agents to support collaborative applications. It proposes that agent supported collaborative systems can be economically built using reusable agents. The paper describes an approach to define generic agents based on a metamodel, which can be used to model a wide range of applications. To do this the paper defines a collaborative metamodel and identifies generic agents based on the metamodel concepts. The paper then describes a methodology that defines systems as object models in terms of the metamodel concepts. The objects in the model are then implemented as components, often using a workspace system. It then supports each component object with the generic agent that corresponds to the component concept.

Computers are now being increasingly used to support collaborative knowledge intensive processes. These are processes where intense interaction takes place between team members with a common goal. The paper identifies technology as an enabler of the collaborative work practices in such processes. To do this technology must provide intuitive interfaces to support such work practices while at the same making it possible to change such interfaces as work practices change. The paper proposes a collaborative metamodel as the basis for defining collaborative work practices and their changing nature. It proposes that the metamodel concepts be provided at the interface to provide commands to adapt interfaces to changing work practices and illustrates this with an implementation. It then suggests that agent support can be a useful enabler to support change

The relationship between the size of a focal plane array in a prime focus dish and achievable scan angle is studied in order to find a starting point for designing such systems. A physical optics model is used to obtain focal plane fields and the radii in the focal plane required to encircle 3 dB and 1 dB below the incident power is calculated for a range of dish diameters and focal length over dish diameter ratios (F/D). The study found the focal plane fields are largely independent of dish size when the scan angle is expressed in beamwidths and gives guidance for the optimal F/D to achieve maximum field of view for a given focal plane array size. © 2005 IEEE.

The algorithm starts from a collection of samples of numbers or letters used in number plates. Edge maps of the samples are then detected based on Spiral Architecture. A set of rules are extracted using these samples by RULES-3. The rules describe the frequencies of 9 different edge masks appearing in the samples. Each mask is a cluster of 7 hexagonal pixels. In order to recognize a number plate, all characters (digits or letters) are tested one by one using the extracted rules. The number recognition is achieved by the frequencies of the 9 masks.

This paper considers the optimization design of the class of allpole analog filters with the objective function that falls out-side the design considerations of classical analog filters. The optimization design is cast into a convex optimization setting whose solution can be obtained using available efficient optimization software. Examples are also provided to validate the effectiveness of the resulting convex design formulation.

In this paper, the possibility and necessity of multistep trajectory planning in Extended Kalman Filter (EKF) based SLAM is investigated. The objective of the trajectory planning here is to minimize the estimation error of the robot and landmark locations subject to a given time horizon. We show that the problem can be regarded as an optimization problem for a gradually identified model. A numerical method is proposed for trajectory planning using a variant of the nonlinear Model Predictive Control (MPC). The proposed method is optimal in the sense that the control action is computed using all the information available at the time of decision making. Simulation results are included to compare the results from the one-step look-ahead trajectory planning and the proposed multi-step lookahead technique

In almost every interaction the trusting peer might fear about the likelihood of the loss in the resources involved during the transaction. This likelihood of the loss in the resources is termed as Risk in the transaction. Hence analyzing the Risk involved in a transaction is important to decide whether to proceed with the transaction or not. If a trusting peer is unfamiliar with a trusted peer and has not interacted with it before in a specific context, then it will ask for recommendations from other peer in order to determine the trusted peer?s Riskiness value or reputation. In this paper we discuss the process of asking recommendations from other peers in a specific context and assimilating those recommendations according to its criteria of the interaction in order to determine the correct Riskiness value of the trusted peer.

Every activity has some Risk involved in it. Analyzing the Risk involved in a transaction is important to decide whether to proceed with the transaction or not. Similarly in Peer-to-Peer communication analyzing the Risk involved in undertaking a transaction with another peer too is important. It would be much easier for the trusting peer to make a decision of proceeding a transaction with the trusted peer if he knows the Risk that the trusted peer is worthy of. In this paper develop and propose such a methodology which allows the trusting peer to rate the trusted peer in terns of Risk that he deserves after the transaction is over.

Decentralized transactions are increasingly becoming popular. These transactions resemble the early forms of the internet and in many ways are regarded as the next generation of the internet. The result will be that this e-commerce transactions approach will shift to peer-to-peer communications rather than client-server environment. However, these peer-to-peer communications or decentralized transactions suffer from some disadvantages, which includes the risk associated with each transaction. This paper focuses on the factors that influence Risk in a decentralized transaction.

Risk is associated with almost every activity that is undertaken on a daily life. Risk associated with Trust, Security and Privacy. Risk is associated with transactions, businesses, information systems, environments, networks, partnerships, etc. Generally speaking, risk signifies the likelihood of financial losses, human casualties, business destruction and environmental damages. Risk indicator gives early warning to the party involved and helps avoid deserters. Until now, risk has been discussed extensively in the areas of investment, finance, health, environment, daily life activities and engineering. However, there is no systematic study of risk in Decentralised communication, which involves e-business, computer networks and service oriented environment. In this paper, we define risk associated with trusted communication in e-business and e-transactions; provide risk indicator calculations and basic application areas.

Every activity has some Risk involved in it. Analyzing the Risk involved in a transaction is important to decide whether to proceed with the transaction or not. Similarly in Peer-to-Peer communication analyzing the Risk involved in undertaking a transaction with another peer too is important. It would be much easier for the trusting peer to make a decision of proceeding a transaction with the trusted peer if he knows the Risk that the trusted peer is worthy of. In this paper develop and propose such a methodology which allows the trusting peer to rate the trusted peer in terms of Risk that he deserves after the transaction is over. © 2005 IEEE.

This study presents an analytical model of radial drainage with vacuum preloading using compressibility indices and varying horizontal permeability and considers the influence of linearly distributed vacuum pressure along the drain. An analytical solution based on the Cylindrical Cavity Expansion theory is used to evaluate the extent of the smear zone along the drain length and predict the performance of an embankment stabilized with vacuum-assisted prefabricated vertical drains at the New Bangkok International Airport (NBIA). Here, a significantly reduced height of sand surcharge could be applied because excess pore pressure was reduced by vacuum preloading. The performance of the embankment was evaluated under different vacuum pressure conditions during which the suction head could not be maintained in the field due to probable air leaks. In the analysis, therefore, the magnitude of applied vacuum pressure was based on field measurements and adjusted accordingly. The settlement predictions based on the writers' solutions were compared and agreed with the available field data. The results also indicate that the efficiency of the vertical drains depends on the extent of the smear zone, the magnitude and distribution of vacuum pressure and the extent of air leak protection provided in the field.

In this paper, performance and parameter optimization of RAKE reception for time-hopping Ultra Wideband (TH-UWB) systems is investigated when interchip interference (ICI) is taken into consideration. For a TH-UWB system, ICI is closely related to the relationship between the number of chips in a frame (Nc), and the period of the TH code (Nf). In a fixed data-rate case, larger Nf implies higher transmitted symbol signal-to-noise ratio (SNR) and larger ICI in RAKE fingers. So there is a tradeoff between Nc and Nf to optimize the RAKE performance. In this paper, two models are suggested to describe the ICI, and this tradeoff is investigated in the single user case based on the traditional Gaussian approximation method and other flexible methods. Given the lack of explicit knowledge of the relationship among Nf, Nc and the interference, a rule of thumb is proposed to configure Nf and Nc. © 2005 IEEE.

In this paper we report on the development of tools that encourage both a creative and reflective approach to music-making and musical skill development. A theoretical approach to musical skill development is outlined and previous work in the area of music visualisation is discussed. In addition the characterisation of music performance as a type of design problem is discussed and the implications of this position for the design of tools for musicians are outlined. Prototype tools, the design of which is informed by the theories and previous work, are described and some preliminary evaluation of their effectiveness is discussed. Future directions are outlined.

In this paper we present a generative system supported by qualitative spatial reasoning. The approach incorporates qualitative modelling in an evolutionary system to automate the design of novel solutions assessed as compatible with a set of existing designs. The system is presented through an application of door design and demonstrates how development guidelines aimed at preserving a building or streetscape's visual character can be met by novel designs. The results presented in this paper illustrate the generation of novel designs that intuitively capture key characteristics of the corpus of existing designs at a qualitative level. This approach provides the basis for new kinds of design tools.

Wear and lubrication characteristics of a multi cylinder diesel engine when operated on vegetable oil blended fuels were studied. The blended fuels consisted of 10, 20, 30, 40, and 50% coconut oil (COIL) (in volume basis) with diesel fuel (DF2). The engine was operated for a total period of 600 hr for six fuels. The same lubricating oil equivalent to SAE 40 was used for all the fuels system. Wear metals, contaminant elements increased with increasing COIL with DF2. An increasing COIL in blends reduced additive elements; and the reduction rate during blends of ≤ 30% COIL was quite similar to DF2. Soot and sulfation reduced with increasing COIL in blended fuels due to reducing aromatics and sulfur in comparison to DP2. The water concentration increased from above 30% COIL blended fuels. The TBN and viscosity changes were almost normal. The engine did not have any starting and combustion noise problems when operating on COIL blended fuels. This is an abstract of a paper presented at the World Tribology Congress III (Washington, DC 9/12-16/2005).

This paper presents experimental results carried out to evaluate wear and lubrication characteristics of a multi cylinder diesel engine when operated on vegetable oil blended fuels. The blended fuels consist of 10%, 20%, 30%, 40% and 50% coconut oil (COIL) (in volume basis) with diesel fuel (DF2). Pure DF2 was used for comparison purposes. The engine was operated at constant speed of 2000 rpm with 50% throttle load for a period of 100 hours for each test fuel. The engine was operated for a total period of 600 hours for six fuels. The same lubricating oil equivalent to SAE 40 was used for all the fuels system. The sample of lube oil was collected through a one way valve connected to the crankcase sump at 50 hour intervals. The first sample was collected immediately after the engine had warmed up. The effect of blended fuel on engine component wear and lubrication characteristics in terms of viscosity, total base number (TBN), moisture content, oxidation, wear metals, contaminant elements and lubricant additive depletions were analyzed. The results showed that wear metals, contaminant elements increase with increasing COIL with DF2. An increasing COIL in blends reduces additive elements; and the reduction rate during blends of up to 30% COIL is quite similar to DF2. Soot and sulfation reduce with increasing COIL in blended fuels due to reducing aromatics and sulfur in comparison to DF2. The water concentration increases from above 30% COIL blended fuels. The TBN and viscosity changes are found almost normal. The engine did not have any starting and combustion noise problems when operating on COIL blended fuels. These lubricating oil analysis data will help to select tribological components and compatible lubricating oil for coconut oil or biofuel operated diesel engines.

This paper presents experimental results carried out to develop co-relation and comparison between vehicle and stationary dynamometer-engine emissions with same engines specifications and brands. The dynamometer-engine has been setup with same load and speed as the vehicle’s engine which is carried on the road. The vehicle’s road load power carried by engine has been calculated and used in this investigation. The stationary engine’s rotational speed has been converted to linear distance to compare specific fuel consumptions (SFC) with real specific fuel consumption (SFC) of the vehicle on the road. The vehicle has been run on road test at 70km/h, 90 km/h and 100 km/h for 100 km each time to measure fuel consumption. Beside this, both the engine and vehicle have been operated in idling condition to measure fuel consumption, CO and HC emissions. Proton vehicle with magma engine (4 cylinders) has been used in this investigation. Both the engine and vehicle have been retrofitted for two fuels namely gasoline fuel and compressed natural gas (CNG). An eddy current dynamometer model Froude Consine (model AG150) is used to test the engine. All the electronic equipment, together with its manipulative controls and indicators such as thermocouples are mounted on ‘CP Cadet10 (UK)’ engine control unit. The engine control unit can control any speed and load applied to the dynamometer-engine. An autocheck model (974/5) and Bacharach model CA300NSX analyzers (standard version, k-type probe) have been used to measure the concentration CO and HC emissions. The results of this investigation will be used to predict the emissions and fuel consumption for road vehicles from stationary dynamometer–engine test.

Abstract This paper presents the experimental results carried out to evaluate the exhaust emissions and performance evaluation of a computer integrated bi-fuel spark ignition engine that has been retrofitted for two fuels namely compressed natural gas (CNG) and base fuel gasoline, operations under steady state with lean burn condition. The used engine was a Proton Magma 4-cylinders spark ignition engine. The emission results such as CO, HC and NOx were measured and compared between the above two fuels. A locally produced three way catalytic converter (TWC) consisting of platinum (Pt), palladium (Pd), cerium oxide (CeO2) and rhodium (Rh) was used to assess the emissions. The CeO2 was used in TWC as an oxygen storage capacity (OSC) to enhance the oxidation process for CO and HC oxidations.

This paper addresses cultural concerns on global websites design and relates them to advanced requirements practices. Developers and users have different ideas of finding information on a web site. There are several factors that differentiate users' understandings of information presented by web designers and this should be considered if a website is desired to be successful worldwide. We observe that cultural concerns may crosscut several base functionalities of a system, constraining and modifying them in different ways. The crosscutting nature of these concerns should be contemplated at early requirements stages of software development to have more adaptable and flexible systems. Aspect-Oriented Requirements Engineering handles crosscutting concerns at requirements level and can be used to model cultural concerns in web applications. This paper examines Australian, Singaporean, German and Brazilian sites and relates them to requirements of users from different countries by identifying the cultural differences that should be taken into account.

This research is an attempt to identify issues of global web design and user preferences particularly from different culture backgrounds. An exploratory study relating to user preferences for design features in popular global sites is presented, and through it identifies a number of factors related to design in the B2C context and proposes a framework based on understanding of users preferences of these factors. Results indicate that users are more likely to use global web sites if they find their favorite features in it. Users form different culture groups and their preferences are likely to influence different levels of design content in a web site. Furthermore, a user with his/her favorite design features that promote users attention and lead to purchase of goods through the global sites.

This paper presents a hands-free head-movement gesture classification system using a Neural Network employing the Magnified Gradient Function (MGF) algorithm. The MGF increases the rate of convergence by magnifying the first order derivative of the activation function, whilst guaranteeing convergence. The MGF is tested on able-bodied and disabled users to measure its accuracy and performance. It is shown that for able-bodied users, a classification improvement from 98.25% to 99.85% is made, and 92.08% to 97.50% for disabled users. © 2005 IEEE.

This paper describes an Infrared Local Positioning System (IR-LPS) designed for indoor UAV use. Directional receivers scan the local environment for active tags that emit a unique (to each tag) IR signal. The system is constructed from inexpensive off the shelf components and requires no room calibration when introduced to a new environment. The IR-LPS is capable of three-dimensional dynamic tracking of a UAV with minimal PC processing power required. This allows for multiple systems to be run from a single PC or for the system to be battery powered and run on an embedded PC. The IR-LPS was implemented and evaluated in a large open space laboratory and provided localisation with less than 1cm error at 2m and with a range of 30m.

View description>>
Use of a Gaussian Sum filter (GSF) to efficiently solve the initialisation problem in bearing-only simultaneous localisation and mapping (SLAM) is the main contribution of this paper. When information about the range is not available, the initial probability density function (pdf) of a landmark in the environment can not be represented using a Gaussian. The GSF is an attractive candidate for estimation in this scenario as it can deal with arbitrary pdfs represented as sets of Gaussians. However, the implementation of the GSF requires maintaining a bank of extended Kalman filters. The resulting computational complexity needs to be reduced by employing a minimum number of filters. In this work, the performance of each extended Kalman filter (EKF) in the GSF is evaluated using the sequential probability ratio test (SPRT). As such the number of members in the Gaussian sum can be reduced rapidly and the efficiency of the GSF can be significantly increased, providing a solution to the important problem of bearing-only SLAM. The effectiveness of the proposed approach is demonstrated by simulation and experiment conducted using a Pioneer mobile robot.

Abstract Background: A field study among 6 reference laboratories in the EU using chromogenic substrate assays revealed in some laboratories a FVIII level lower than expected when measuring the potency of ReFacto, a B-domain deleted recombinant FVIII concentrate. In an attempt to resolve these discrepancies, the standard used for establishing the potency of ReFacto was recalibrated in 2003. Indeed after this recalibration, the amount of ReFacto protein in each International Unit (IU) has increased by approximately 20 percent without change in the labeled dosage strength. Objectives: The primary objective of this prospective study was to assess the FVIII recovery in severe hemophilia A patients receiving recalibrated ReFacto. Methods: The study was conducted in 10 French Hemophilia Treatment Centers in Previously Treated Patients (> 150 exposure days to any FVIII concentrate). A series of 4 blood samples per patient were collected in a non-bleeding state, respectively before, 15mn, 30mn and 60mn after intravenous bolus infusion of a single dose of 50 ±5 IU/kg of ReFacto. Plasma FVIII activity was determined in a central lab using a chromogenic substrate assay (Coamatic FVIIITM). Results: Fourteen severe hemophilia A patients (FVIII: C < 1%) were evaluable for intention to treat analysis. Median age was 25.5 years (range: 12–48). Median injected dose was 53.3 UI/kg (range 48.4–56.8). Maximal plasma FVIII activity level was obtained 15mn (n=10) or 30 mn (n=4) after the end of infusion. Mean incremental recovery (K value) was 2.20 ±0.27 UI/dL per UI/kg infused (range: 1.89–2.75) with a mean in vivo recovery of 105.2% (range: 87.6–133.8). Conclusions: In most cases the peak of FVIII activity was obtained 15 mn after the end of infusion. Recovery of recalibrated ReFacto was simila...

The main contribution of this paper is an algorithm for autonomous search that minimizes the expected time for detecting multiple targets present in a known built environment. The proposed technique makes use of the probability distribution of the target(s) in the environment, thereby making it feasible to incorporate any additional information, known a-priori or acquired while the search is taking place, into the search strategy. The environment is divided into a set of distinct regions and an adjacency matrix is used to describe the connections between them. The costs of searching any of the regions as well as the cost of travel between them can be arbitrarily specified. The search strategy is derived using a dynamic programming algorithm. The effectiveness of the algorithm is illustrated using an example based on the search of an office environment. An analysis of the computational complexity is also presented. © 2005 IEEE.

View description>>
The detection of damage in reinforced concrete bridge using vibration characteristics has been the topic of much research in the last two decades. Since reinforced concrete structures are nonlinear in behaviour, even with relatively low levels of damage, it is difficult to make a reliable estimate on the modal properties for use in the damage detection/health monitoring. The Hilbert-Huang transform (HHT) comprises the empirical mode decomposition (EMP) of the data and performing the Hilbert transform (HT) on each mode, and it is an effective method to analyze the nonlinear and non-stationary time series data. This study focuses on studying the signature of non-linear characteristics in the vibration of damaged reinforced concrete beams using HHT, and to investigate the possibility of using changes in these nonlinear vibration characteristics to detect damage in reinforced concrete structures. Vibration tests of several reinforced concrete beams with different damage scenarios are conducted in laboratory. The measured signals are decomposed into intrinsic mode function (IMF) using EMP and the Hilbert-Huang spectrum is obtained by the HT of each IMF. Results show that the method based on Hilbert-Huang spectral analysis is quite effective for the damage assessment of the reinforced concrete structures.

Simulation of large-scale networks requires enormous amounts of memory and processing time. One way of speeding up these simulations is to distribute the model over a number of connected workstations. However, this introduces inefficiencies caused by the need for synchronization and message passing between machines. In distributed network simulation, one of the factors affecting message passing overhead is the amount of cross-traffic between machines. We perform an independent benchmark of the Parallel/Distributed Network Simulator (PDNS) based on experimental results processed at the Australian Centre for Advanced Computing and Communications (ACS) supercomputing cluster. We measure the effect of cross-traffic on wall-clock time needed to complete a simulation for a set of basic network topologies by comparing the result with the wall-clock time needed on a single processor. Our results show that although efficiency is reduced with large amounts of cross-traffic, speedup can still be achieved with PDNS. With these results, we developed a performance model that can be used as a guideline for designing future simulations. © 2005 IEEE.

This paper provides a solution to the optimal trajectory planning problem in target localisation for multiple heterogeneous robots with bearing-only sensors. The objective here is to find robot trajectories that maximise the accuracy of the locations of the targets at a prescribed terminal time. The trajectory planning is formulated as an optimal control problem for a nonlinear system with a gradually identified model and then solved using nonlinear Model Predictive Control (MPC). The solution to the MPC optimisation problem is computed through Exhaustive Expansion Tree Search (EETS) plus Sequential Quadratic Programming (SQP). Simulations were conducted using the proposed methods. Results show that EETS alone performs considerably faster than EETS+SQP with only minor differences in information gain, and that a centralised approach outperforms a decentralised one in terms of information gain. We show that a centralised EETS provides a near optimal solution. We also demonstrate the significance of using a matrix to represent the information gathered. © 2005 IEEE.

We are often interested to test whether a given cause has a given effect. If we cannot specify the nature of the factors involved, such tests are called model-free studies. There are two major strategies to demonstrate associations between risk factors (ie. patterns) and outcome phenotypes (ie. class labels). The first is that of prospective study designs, and the analysis is based on the concept of "relative risk": What fraction of the exposed (ie. has the pattern) or unexposed (ie. lacks the pattern) individuals have the phenotype (ie. the class label)? The second is that of retrospective designs, and the analysis is based on the concept of "odds ratio": The odds that a case has been exposed to a risk factor is compared to the odds for a case that has not been exposed. The efficient extraction of patterns that have good relative risk and/or odds ratio has not been previously studied in the data mining context. In this paper, we investigate such patterns. We show that this pattern space can be systematically stratified into plateaus of convex spaces based on their support levels. Exploiting convexity, we formulate a number of sound and complete algorithms to extract the most general and the most specific of such patterns at each support level. We compare these algorithms. We further demonstrate that the most efficient among these algorithms is able to mine these sophisticated patterns at a speed comparable to that of mining frequent closed patterns, which are patterns that satisfy considerably simpler conditions.

Reinforced concrete (RC) structural elements can be strengthened by bonding high-strength, noncorrosive fibre reinforced polymer (FRP) composites to their surfaces. In the majority of strengthening situations the existing structure would have been subjected to extreme loading at some stage of its life. It is of great interest to designers and users of structures to be aware of the condition of the structural elements, particularly with regards to damage, prior to the design and application of FRP strengthening measures. This paper reports the results of a vibration-based method for assessing damage in RC beams prior to and after the application of FRP strengthening. The vibration-based method measures the vibrations of beams with and without additional mass and provides an assessment of the degree of damage as well as stiffness of the structural element. A simply supported RC beam was constructed and initially damaged by loading to 50% of its flexural capacity. FRP strengthening was then applied and the beam tested to failure. Vibration measurements were taken prior to and after damage of the plain beam as well as after application of the FRP strengthening. The proposed method was used for detecting damage and evaluating the repair as well as quantitatively estimating in-service stiffness of the beams. Good correlation between dynamic results and static load test results is found, thus demonstrating the potential of the vibration-based method. © Institute of Materials Engineering Australasia Ltd 2005.

The pricing and hedging of complex derivative securities via Monte Carlo simulations of stochastic differential equations constitutes an intensive computational task. To achieve 'real time' execution, as often required by financial institutions, one needs highly efficient implementations of the multi-point distributed random variables underlying the simulations. In this paper a fast and flexible dedicated hardware solution is proposed. A comparative performance analysis demonstrates that the hardware solution is bottleneck-free and flexible, and significantly increases the computational efficiency of the software solution. © 2005 IEEE.

Multi-point distributed random variables whose moments match those of a Gaussian random variable up to a certain order play an important role in Monte Carlo simulations of weak approximations of stochastic differential equations. In applications such as finance, where "real time" execution is required, there is a strong need for highly efficient implementations. In this paper a fast and flexible dedicated hardware solution on a Field Programmable Gate Array (FPGA) is presented. A comparative performance analysis between a software-only and the proposed hardware solution demonstrates that the FPGA solution is bottleneck-free, retains the flexibility of the software solution and significantly increases the computational efficiency.

Developments of e-learning technologies are generating great impact in the field of education services to overcome geographical displace and improve the collaborative group work environment. Previous researches about e-learning system have introduced many concepts to generate fundamental groundwork such as tools for managing the contents of course materials, students' records and assessments information. However, the great potential of e-learning technologies according to web lecturing and collaborative group work can still be explored for maximizing the interactions among users. This paper proposed a web-based multimedia system for e-learning management application with an advanced streaming web lecturing module and an additional of a communication tools developed according to the concept of Computer Supported Cooperative Work (CSCW). With the ability of tracking multiple objects simultaneously, the proposed streaming web lecturing can satisfy and improve the requirements of a virtual classroom. The efficiency of collaboration and consultation is increased by providing an online chat session and simultaneous group web browsing environment that user could aware the presence of other participants.

The intention of managing agent interactions between agents residing in a virtual collaborative environment is to obtain some useful beliefs that can be used in agent reasoning and decision making in order to optimize further agent interactions. Agent business relationships (such as trust, loyalty, understanding and friendship) are such beliefs. This research provides an approach to the management and application of agent interaction instances. The paper firstly introduces the multi-agent system architecture built in the virtual collaborative environment. Secondly, it presents the interaction protocols designed for the software agents. Then, it describes the design and implementation of the management of interactions. Finally, it depicts a specific belief revision function for personal agents to dynamically update agent business relationships in terms of the management of agent interaction instances. © 2005 by International Federation for Information Processing.

This paper proposes a novel approach for texture classification by feature extraction based on cellular neural networks (CNN's) and an intelligent arrangement in the design or exact using of the templates in CNN's. This paper also gives a two-way processing mechanism including the analysis of features extracted from the output of CNN's mapping and a selective training step for obtaining the specific templates in CNN's by genetic algorithms (GA's) for more complicated texture patterns. In this paper, we introduce a one dimensional feature curve as well to indicate the characteristics of original texture patterns from the mapping of the output of CNN's for the latter texture classification. The method introduced in this paper could adaptively choose an appropriate processing procedure for the specific issues towards in specific texture patterns. We finally divide our experiments into two sections, for simple and advanced problems in texture classification. Our experimental results demonstrate the valid template training and at the same time show a satisfactory classification outcome in both defined texture problems.

A novel 2D to 3D effect image conversion architecture integrated image segmentation system and depth estimation is presented. Its objective is to describe the technique used to generate stereo pair images starting from a single image source (a view-point) and its related depth map. The conjunction between segmented image and depth map allows reconstructing artificially the binocular view producing a 3D effect depending on screen dimension and image resolution. The system consists of an on-line ICA mixture model that performs image segmentation and depth estimation method to obtain the depth information of image. The proposed system is capable to perform automatic multilevel segmentation of images, based on depth information obtained by the image depth estimation method. The system does not reconstruct the real 3D coordinates of any object inside the scene, but simply assigns the most comfortable shift to the source points to give a 3D-entertainment to the viewer. A simple smoothing filtering technique adaptively resolves the occlusions generated by shifting of the source points without introducing visible and/or annoying artifacts.

A fuzzy neural network based on support vector learning mechanism for function approximation is proposed in this paper. Support vector regression (SVR) is a novel method for tackling the problems of function approximation and regression estimation based on the statistical learning theory. SVR has been shown to have robust properties against noise. A novel support-vector-regression based fuzzy neural network (SVRFNN) by integrating SVR technology into FNN is developed. The SVRFNN combines the high accuracy and robustness of support vector regression (SVR) and the efficient human-like reasoning of FNN for function approximation. Experimental results show that the proposed SVFNN for function approximation can achieve good approximation performance with drastically reduced number of fuzzy kernel functions. © 2005 IEEE.

In stock market or other financial market systems, the technical trading rules are used widely to generate buy and sell alert signals. In each rule, there are many parameters. The users often want to get the best signal series from the in-sample sets, (Here, the best means they can get the most profit, return or Sharpe Ratio, etc), but the best one will not be the best in the out-of-sample sets. Sometimes, it does not work any more. In this paper, the authors set the parameters a sub-range value instead of a single value. In the sub-range, every value will give a better prediction in the out-of-sample sets. The improved result is robust and has a better performance in experience.

In this paper, on the basis of features and attributes of foreign currency exchange trading streams, we discuss and compare multiple approaches including interactive zooming, multiform sampling with combination of attribute of large foreign currency exchange data, and fish-eye view embedded visualization for visual display of high-density foreign currency exchange transactions. By comparison, Fish-eye-based visualization is the best option, which can display regional records in details without losing global movement trend in the market in a limited display window.

As a rapidly growing field, Autonomic Computing is a promising new approach for developing large scale distributed systems. However, while the vision of achieving self-management in computing systems is well established, the field still lacks a commonly accepted definition of what an Autonomic Computing system is. Without a common definition to dictate the direction of development, it is not possible to know whether a system or technology is a part of Autonomic Computing, or if in fact an Autonomic Computing system has already been built. The purpose of this paper is to establish a standardised and quantitative definition of Autonomic Computing through the application of the Quality Metrics Framework described in IEEE Std 1061-1998 [1]. Through the application of this methodology, stakeholders were systematically analysed and evaluated to obtain a balanced and structured definition of Autonomic Computing. This definition allows for further development and implementation of quality metrics, which are project-specific, quantitative measurements that can be used to validate the success of future Autonomic Computing projects.

With the birth of DNA computing, Paun et al. proposed an elegant algorithm to this problem based on the sticky model proposed by Roweis. However, the drawback of this algorithm is that the 'exponential curse' is hard to overcome, and therefore its application to large instance is limited. In this s paper, we present a DNA based evolutionary algorithm to solve this problem, which takes advantage of both the massive parallelism and the evolution strategy by traditional EAs. The fitness of individuals is defined as the negative value of their length. Both the crossover and mutation can be implemented in a reshuffle process respectively. We also present a short discussion about population size, mutation probability, crossover probability, and genetic operations over multiple points. In the end, we also present some problems needed to be further considered in the future. © Springer-Verlag Berlin Heidelberg 2005.

Architectural design is a critical phase in building agent-based systems. However, most of existing agent-oriented software engineering approaches deliver weak or incomplete supports for the architectural design of distributed and especially Internet-based agent systems. On the other hand, the emergence of service-oriented computing (SOC) brings in intrinsic mechanisms for complementing agent-based computing (ABC). In this paper, we investigate the dialogue between ABC and SOC and their integration in implementing architectural design. We synthesize them and develop the computational concept agent service, and build a new design approach called agent service-oriented architectural design (ASOAD). The ASOAD expands the contents and ranges of agent and ABC, and synthesize the qualities of SOC such as interoperability and openness with the performances of ABC like flexibility and autonomy. It is suitable for designing distributed agent systems and agent service-based enterprise application integration.

Limitations in the contemporary best effort WAN combined with an increase in demand of the business users for multimedia are the main challenges for remote desktop solutions. Thin client remote desktop protocols are now mature enough to work efficiently over low bandwidth and low quality links for normal office applications. However, they face significant challenges when working with more demanding data flows such as multimedia streams. This paper introduces the server-side component of the architecture for remote desktop environment aiming at improving user perception of the more demanding and network sensitive multimedia applications and services. Our component maps of user-perceived Quality of Service (QoS) onto network-level performance parameters in order to improve overall end-to-end QoS. The set of perception rules defined for each application and type of user triggers the adaptation mechanisms to change the transmission parameters in order to meet end user expectations. The adaptation mechanisms can optimize the usage of the available network resources within a dedicated network link both for different flows within single client connection and for all clients connected to the same server module. The result of such an optimization is a new set of connection parameters adjusted to network state changes and user perception of remote desktop. In the paper we discuss requirements of such QoS control mechanisms and respective adaptation mechanisms, followed by the detailed description of the proposed component architecture.

Active probing heuristics are usually based on queuing systems. However, a rigorous probabilistic treatment of probing methods has been lacking. For instance, it is not known even in principle, what can and cannot be measured in general, nor the true limitations of existing methods. We provide a probabilistic treatment for the measurement of cross traffic in the 1-hop case. We derive inversion formulae for the cross traffic process, and explain their fundamental limits, using an intuitive geometric framework.

Intelligence agencies face a knowledge transfer dilemma. They have compelling reasons to invest in codification, to structure and store knowledge about critical infrastructure and terrorist threats, and enable sharing with allied departments and governments. Threat information has a high obsolescence rate and short half-life: it is actionable before the attack, but not after. Timely response to terrorist chatter requires rapid diffusion of information, in codified form, to enforcement personnel. But, problematically, codification of infrastructure and threat information increases the diffusability of such knowledge, making it increasingly accessible to terrorists, who can use the information in planning new attacks or revising existing plans. This paper introduces a graphical simulation environment, I-Space 2, which has been built for simulating knowledge management processes, and illustrates its potential application to the knowledge-transfer dilemma facing the counter-terrorism community.

To remain competitive, companies are starting to organise their work around customer-centered business processes that cross functional and organisational boundaries. Customer-relationship management is becoming more important than ever before. This paper proposes a new type of process-oriented CRM system suitable for Small-to-Medium Enterprises (SMEs) seeking to integrate a large number of service providers and services and create an added value for their customers. Process-support is enabled by component-based workflow technology. Design of this system is based on a flexible model of declarative business processes that is also briefly described in the paper. To illustrate the importance of the proposed type of CRM support, the paper uses an example of an Australian service-oriented SME.

Supported by technology, organizations are becoming more dynamic, adaptive and networked. A term ambient organizations is used to describe evolving organisational forms, enabled by integrated information systems that are designed to support customercentered business processes and to enhance flexibility and knowledge sharing across functional and organisational boundaries. In ambient organizations, customers become the central focus and various strategies are implemented to involve them as "business partners" or virtual resources. This paper investigates ambient organizations within the context of SMEs (Small-to-Medium Enterprises) with the special emphasis on enabling IT solutions. It then illustrates the concept by an example of a service-oriented SME.

This paper asserts that the implementation of fulfilment and assurance within Telecommunications management with a strong reference to an Information Model (IM) progresses and allows for the advantages of an integrated approach to service delivery. We assert that if the fulfillment process follows and is compliant to an IM based process then other processes such as within assurance can leverage the IM for effectiveness by utilizing the information from fulfillment time to assist in efficiently implementing the assurance side.

An Information Model continues to be a fundamental constituent in understanding complex environments. The TMFs eTOM is a complete business process oriented view of a senice provider and the SID is being positioned as the information model. It is claimed that the use of an extended and expanded version of Policy Based Management can automate many of the processes. This paper examines how PBNM, eTOM and SID can be combined to achieve an automated SLA monitoring service. It maps the assurance (monitoring) portion of the SLA process onto the TMF SID inlormation model detail@ the used SLA entities and policy rules involved.

This paper focuses on providing an information model view of the Trouble component of the assurance domain. This is derived using an understanding of the TMF eTOM processes and the associated SID Information Model through its application to the Trouble processes. We begin by examining existing standards and adapt and/or derive entities which are used within these processes and develop some entities which are undefined or unavailable currently in the SID definitions. We describe an implementation that leverages the use of the SID information model principles to enhance Trouble assurance.

In Monte Carlo simulation of weak approximation of stochastic differential equations, multi-point distributed random variables play an important role. However, they need highly efficient implementations to meet the 'real-time' requirements of applications such as the pricing of complex derivative securities. In this paper a fast and fexible dedicated hardware generator of multi-point distributed random variables on a Field Programmable Gate Array (FPGA) is presented. A comparative performance analysis demonstrates that the hardware solution is bottleneck-free, retains the fexibility of a traditional software implementation and significantly increases the computational fficiency of the overall simulation. © 2005 IEEE.

With the ever-growing pace of technological advancement, computer software is required to become increasingly complex to meet the demands of today's leading edge technologies, and their applications. However, fulfilling this requirement creates new, previously unknown, problems pertaining to non-functional properties of software. Specifically, as the software complexity escalates, it becomes increasingly difficult to scale the software in order to cope with the sometimes overwhelming demand created by system growth. It is therefore essential to have processes for addressing the issues associated with scalability that arise due to the complexity in software systems. In this paper we describe an approach aimed at fulfilling the need for such processes. A combination of Object-Z and temporal logic is used to create an architectural description open to further analysis. We also demonstrate the practicality of this methodology within the context of the coordinated adaptive traffic system (CATS).

Having come of age in the last decade, the use of architecture to describe complex systems, especially in software, is now maturing. With our current ability to describe, represent, analyse and evaluate architectures comes the next logical step in our application of architecture to system design and optimisation. Driven by the increasing scale and complexity of modern systems, the designers have been forced to find new ways of managing the difficult and complex task of balancing the quality trade-offs inherent in all architectures. Architecture-based optimisation has the potential to not only provide designers with a practical method for approaching this task, but also to provide a generic mechanism for increasing the overall quality of system design. In this paper we explore the issues that surround the development of architectural optimisation and present an example of heuristic-based optimisation of a system with respect to concrete goals.

This paper presents a multi-stage shared control method (MSSC) which can be used to control the movement of a robotic mobility assistant designed to facilitate safe mobilization for people with unstable gait. The multi-stage control module consists of user intent, obstacle avoidance and fuzzy logic components. The user intent represents the person's commands. The obstacle avoidance component reads data representing any obstacles in the vicinity of the assistant and uses the Vector Field Histogram (VFH) algorithm to select a suitable path to avoid any obstacles in the path of travel. The fuzzy logic component is responsible for merging the user intent and obstacle avoidance information such that the user's request is satisfied to the highest extent possible. When an unsafe situation presents itself the user's request(s) will be partially or wholly overridden so the assistant can return to a safe state. The system has been designed to be dynamically configurable so as to suit different users in terms of gait stability and strength, preferred speed of travel and level of control over the system. It has been tested both in a simulated environment and real-world operating conditions and has been shown to effectively avoid obstacles with minimal disruption to the user and their intent. ©2005 IEEE.

We use an information theory approach to investigate the role of mutation on Genetic Algorithms (GA). The concept of solution alleles representing information in the GA and the associated concept of information density, being the average frequency of solution alleles in the population, are introduced. Using these concepts, we show that mutation applied indiscriminately across the population has, on average, a detrimental effect on the accumulation of solution alleles within the population and hence the construction of the solution. Mutation is shown to reliably promote the accumulation of solution alleles only when it is targeted at individuals with a lower information density than the mutation source. When individuals with a lower information density than the mutation source are targeted for mutation, very high rates of mutation can be used. This significantly increases the diversity of alleles present in the population, while also increasing the average occurrence of solution alleles.

We study the problem of affective content analysis. In this paper -we think of affective contents as those video/audio segments, which may cause an audience's strong reactions or special emotional experiences, such as laughing or fear. Those emotional factors are related to the users' attention, evaluation, and memories of the content The modeling of affective effects depends on the video genres. In this work, we focus on comedy and horror films to extract the affective content by detecting a set of so-called audio emotional events (AEE) such as laughing, horror sounds, etc. Those AEE can be modeled by various audio processing techniques, and they can directly reflect an audience's emotion. We use the AEE as a clue to locate corresponding video segments. Domain knowledge is more or less employed at this stage. Our experimental dataset consists of 40-minutes comedy video and 40-minutes horror film. An average recall and precision of above 90% is achieved. It is shown that, in addition to rich visual information, an appropriate usage of special audios is an effective way to assist affective content analysis. © 2005 IEEE.

This paper presents a practical approach to solve the simultaneous localization and mapping (SLAM) problem for autonomous mobile platforms by using natural visual landmarks obtained from an stereoscopic camera. It is an attempt to depart from traditional sensors such as laser rangefinders in order to gain the many benefits of nature-inspired information-rich 3D vision sensors. Whilst this makes the system fully observable in that the sensor provide enough information (range and bearing) to compute the full 2D estate of the observed landmarks from a single position, it is also true that depth information is difficult to rely on, particularly on measurements beyond a few meters (in fact the full 3D estate is observable, but here robot motion is constrained to 2D and only the 2D problem is considered). The work presented here is an attempt to overcome such a drawback by tackling the problem from a partially measurable SLAM perspective in that only landmark bearing from one of the cameras is employed in the fusion estimation. Range information estimates from the stereo pair is only used during map building in the landmark initialization phase in order to provide a reasonably accurate initial estimate. An additional benefit of the approach presented here lies in the data association aspect of SLAM. The availability of powerful feature extraction algorithms from the vision community, such as SIFT, permits a more flexible SLAM implementation separated from feature representation, extraction and matching, essentially carrying out matching with minimal recourse to geometry. Simulation results on real data illustrate the validity of the approach. © 2005 IEEE.

In this article, the performances of positioning technologies in Ultra Wide Band (UWB) and Wideband CDMA (WCDMA) systems are compared. Three positioning algorithms are studied, namely the Taylor Series (TS), Davidon-Fletcher-Powell (DFP) and the Direct Method (DM). Results obtained with complete simulation platforms, including channel estimation, synchronization, modulation and detection, are utilized to compare the two technologies. First, the Time-of-Arrivals (ToAs) obtained with the simulators are used to compute source positions, giving lower bounds on their estimation errors. Then, the signals obtained from the simulators are input into the three algorithms considered. Finally the accuracies of positioning with both technologies are quantified by comparing the Root-Mean-Square Error (RMSE) of their respective estimation results using 4 or 5 BSs. The failure rate of the algorithms are also investigated. © 2005 IEEE.

The data mining inspired problem of finding the critical, and most useful features to be used to classify a data set, and construct rules to predict the class of future examples is an interesting and important problem. It is also one of the most useful problems with applications in many areas such as microarray analysis, genomics, proteomics, pattern recognition, data compression and knowledge discovery. Expressed as κ-Feature Set it is also a formally hard problem. In this paper we present a method for coping with this hardness using the combinatorial optimisation and parameterized complexity inspired technique of sound reduction rules. We apply our method to an interesting data set which is used to predict the winner of the popular vote in the U.S. presidential elections. We demonstrate the power and exibility of the reductions, especially when used in the context of the (α β)κ-Feature Set variant problem. Copyright © 2005, Australian Computer Society, Inc.

Some trading strategies are becoming more and more complicated and utilize a large amount of data, which makes the backtesting of these strategies very time consuming. This paper presents an efficient implementation of the backtesting of such a trading strategy using a parallel genetic algorithm (PGA) which is fine tuned based on thorough analysis of the trading strategy. The reuse of intermediate results is very important for such backtesting problems. Our implementation can perform the backtesting within a reasonable time range so that the tested trading strategy can be properly deployed in time. © Springer-Verlag Berlin Heidelberg 2005.

As part of a continuing program of investigations into roadside traffic noise barrier optimisation, the NSW Roads and Traffic Authority (RTA) funded a research and development study to develop and evaluate several full size prototype barrier designs. Of particular interest to this study was a design known as a Random Edge Profile Barrier since there was a body of published evidence which indicated that a barrier of this type can cause a substantial degradation of the noise diffracted over the barrier edge. As a consequence, it has been suggested that such barriers are capable of providing improved traffic noise attenuation compared to conventional barriers. The present study involved an empirical evaluation of a prototype Random Edge Profile Barrier and the comparison of its performance with that of conventional barriers and also with that which is known as a T-Top barrier. In total four barriers types were constructed alongside a major rural freeway in NSW and were 80m long by either 2.4m or 3.0m high. A substantial body of empirical data were collected at various receiver locations in front of, behind and adjacent to each barrier. Analyses of these data showed that for the receiver locations investigated, the random edge barrier out-performed the conventional barrier of the same nominal height for most frequencies associated with broadband tyre/road noise. The T-Top barrier was found to perform the best for frequencies greater than 3.15 kHz whilst the conventional barrier offered the most practical solution for attenuation of low frequency noise.

Software is developed and implemented by enterprises that wish to increase their efficiency and effectiveness. This process is often undertaken by persons who have little or no formal training in the field, particularly in developing countries. The results are frequently disadvantageous and often fatal to the enterprise. The University of Technology, Sydney has designed a special short postgraduate program targeted at persons in developing countries who have or wish to have such software responsibility. The response to this program has proven to be significant as it provides a fast and effective approach to increasing the software project management capability. Copyright © 2005 IFAC.

This paper analyses the behaviour and evaluates the performance of a new QoS DiffServ model, called FICC-DiffServ, as implemented in [I]. The implementation proposed a comprehensive framework for DiffServ networks. In the model, the fair intelligent congestion control (FICC) algorithm is applied to provide fairness among traffic aggregates and control congestion inside the networks. Simulation results show that the FICC-DiffServ is robust and simple to implement. It provides excellent fairness and minimizes the packet delay and jitter under a wide range of variations of both internal and external network conditions. In addition, the paper investigates the dynamicity of the overall system by studying the impact of its target operating point on the overall system performance and suggesting a scheme to adjust the operating point adaptively

Matching tracks from a single individual across disjoint camera views is a challenging task in video surveillance. In this paper, a Major Color Spectrum Histogram representation (MCSHR) is introduced to represent a moving object by using a normalized distance between two points in the RGB space. Then, an incremental MCSHR is proposed to cope with small pose changes and segmentation errors occurring along the track. Finally, a similarity measurement algorithm is proposed based on the incremental MCSHR to measure the similarity of any two tracked moving objects. The proposed similarity measurement algorithm proved capable of measuring the similarity of the two moving objects accurately. Experimental results show that with three to five frames integration, the proposed incremental MCSHR algorithm can make matching more robust and reliable than single-frame matching, especially for small pose changes. The matching performance is not obviously improved instead when the number of integration is more than five. The similarity of a same moving object in two different tracks has been improved from 92% to 95% with the integration number increased from three to five, while two different moving objects have been easily discriminated. The proposed algorithm can be used to match tracks from single individuals in camera networks which do not provide full coverage of the monitored space. © 2005 IEEE.

In the ambiguous, high stress, and time sensitive environment of mission critical emergency operations, the decision-making process could benefit from a distributed pattern of mobile resources across a wireless network. Dealing with challenges in these environments, mobile agents can move across the wireless setup, having many promising attributes including autonomy, adaptability, and persistency. These attributes make them able to act independently, to sense and interact with their environment and to make decisions on behalf of the users. Mobile agents are particularly suitable for the situations where the distributed information throughout a network is crucial for other applications/services/agents which heavily rely on, and are sensitive to situation-based and well-timed information. Until now there has been a lack of studies that approach issues of disaster response in a way that integrates these technologies while also considering the human and organisational perspectives. In this paper we present and investigate an intense man-made disaster. Results show that mobile agents can in many ways augment the performance of communication systems working in extreme environments of mission critical emergency operations.

Edge detection plays an important role in image processing area but is still an open problem. This paper presents a novel edge detection method based on bi-lateral filtering which achieves better performance than single Gaussian filtering. In this form of filtering, both spatial closeness and intensity similarity of pixels are considered in order to preserve important visual cues provided by edges and reduce the sharpness of transitions in intensity values as well. In addition, the edge detection method proposed in this paper is achieved on hexagonally sampled images. Due to the compact and circular nature of the hexagonal lattice, a better quality edge map is obtained on hexagonal architecture than common edge detection on square architecture. Experimental results using our proposed method in this paper exhibit encouraging performance. © 2005 IEEE.

This paper focuses on metadata-based, multimedia resource representation and retrieval in a P2P environment as a means of Universal Multimedia Access (UMA). The primary focus of the work is a P2P architecture which uses MPEG-21 as a standards based technique to dynamically adapt resources to various usage environments. In the architecture, a super peer based approach is used to cluster peers, store peer information, perform searches and instruct peers to adapt/send resources. Also a two-stages based adaptation method is introduced to adapt search results and resources in an intelligent manner based on the usage environment attributes. The concept is demonstrated using a test-bed built based on the JXTA peer-to-peer frame-work. In addition, simulation results show that the proposed architecture reduces download time while increasing resource availabilities and download speed in the network when compared to traditional P2P systems. © 2004 IEEE.

A dynamic P2P architecture based on MPEG-21 was proposed in our previous work to support resource adaptation/personalization according to the surrounding usage environment and user preferences. In this paper, we improve the proposed system through two separate but related modifications. Firstly, peers are clustered according to registered geographic location information. Secondly, based on that registered location information, a locality-based service is introduced which allows users to search services according to their geographic locations. The service complements the proposed P2P architecture by encouraging service providers to increase the uptime of their devices and hence provide the spare computer power for active adaptation of resources for low-end peers. Simulation results show that the proposed approach reduces download time and network delays while increasing resource availability and download speed in the network.

IT adoption within SMEs has been covered extensively within literature, most of which have considered IT adoption from narrow perspective such as drivers and barriers of IT adoption. IT adoption is better defined as a process which involves organisation and its components, stakeholders external to the organisation, and interactions within organisation and between organisation and its stakeholders. This paper uses multi perspective in IT adoption to build model of IT adoption. A field study involving 35 Indonesian SMEs was conducted in the form of semi structured interviews. The result from this field study were analysed and used to refine the proposed model. © 2005.

Small and Medium Enterprises (SMEs) sometimes acquire information systems that fail to meet their original aims and objectives. In these circumstances, the project sponsors are forced to decide whether they should abandon the system they have paid for or improvise by finding a way around the problem. This paper presents a case study with two Indonesian SMEs who had to deal with information systems failure within their organizations. Although within the information systems literature reports of these types of failure can be found but little is known about the aftermath of failure within SMEs. This case study presents the actions taken by two Indonesian SMEs who had to face with the failure of their web catalogue systems. The notion of IS failure used in this paper is a combination of 'expectation failure' and 'termination failure'.

Many existing management systems are not evolutive or adaptive, leading to multiplicity over time and increasing the management burden. Policy-based management approaches may assist in making networks less complex and more automated, but to date they have not yet been able to evolve to support new service sets or provide the capacity for differentiation. We present the architecture for a policy-based system named Pronto that helps to deal with these issues. Layered network and service models are built above an extensible virtual device model that supports heterogenous management interfaces. Interchangeable management components provide the basic building blocks to construct logical services. The integrated policy-driven service definition language automates the management of the services in a manner that is adaptive, dynamic and reactive to improve the user's overall service experience. © 2005 IEEE.

Our previous work proposed a simple algorithm for the distribution and coordination of network management policies across a number of autonomous management nodes by partitioning an Abstract Syntax Tree into different branches and specifying coordination points based on data and control flow dependencies. We now extend this work to support more complex policies containing control flow logic and looping, which are part of the PRONTO policy language. Early simulation results demonstrate the potential performance and scalability characteristics of this framework.

Legged robots offer exceptional mobility in uncharted terrains. Their dynamic nature yields unrivaled mobility, but serves to destabilize the motion estimation process that underlies legged operations. In particular, the discontinuous foot fall patterns and flight phases result in severe impulses, which, in turn, result in excessive accumulation of drift by inertial sensors. Ground range measurements, amongst several others, are robust to this drift yet are limited in application due to their low-bandwidth and sensitivity to ground conditions. In considering the attitude estimation problem for this dynamic legged locomotion, this paper develops a pose calculation method based on ground range measurements. This is used in conjunction with a hybrid Extended Kalman Filter that takes advantage of the ballistic nature of the flight phases. Results indicate that this combination provides rapid, robust estimates of attitude necessary for extended dynamic legged operations. In single leg experiments, which were conducted using low-cost sensing hardware, this method had an RMS error of < 1 °, half that of a non-hybrid EKF approach.

With the onset of the Internet the perception of computing systems in general has revolutionised. Areas of research have migrated from developing nodes to building networks - thus requiring the need for a variety of information processing techniques, such as clustering, classification, dependency modelling and others. However, the applications of Sensor Networks are yet to evolve in such proportions. Some of the primary constraints being the resources available in an embedded environment, the need to dynamically configure services to carry out a variety of tasks, communication interfaces and sensing and monitoring techniques. This paper discusses a holonic analysis to aid in mitigating ill-structured and often problematic situations that are often characterized by uncertainty in reasoning and the varying nature of relationships with associated elements. The proposed methodology is a synergy between the classic model derived from Soft Systems Methodology (SSM) and the model of Systemic Analysis through Familiar Entities (SAFE). Development of an Intelligent Security System (ISS) has been considered to be an ideal test-bed for this synergy to go through the phases of problem definition and exploration, development of conceptual models and generation of insight to stimulate acceptable and feasible changes. The technical aspect of this system encompasses the mode of query processing and surveillance through a structured sensor network set up with the aid of distributed services and network protocols. © 2005 IEEE.

In the design and construction of modern structures such as highrise buildings and long-span bridges, it is extremely important that realistic creep behaviour of concrete is known and used. In the 2003-2004 revision of the Australian Standard for concrete structures AS 3600, a new set of 'basic creep factors' or 'basic creep coefficients' are given to cover a wide range of concrete with characteristic strengths up to 100 MPa. This paper presents the background work undertaken to determine the basic creep factors. As part of this research, the suitability of various methods of extrapolating long-term creep from short-term creep tests were evaluated. The creep characteristics of a range of concretes were measured under sustained load in accordance with AS 1012.16. The concrete mixtures cover a range of constituent materials including a general purpose (GP) cement, an Australian version of an ordinary portland cement, binary and tertiary blends of GP with ground granulated blast furnace slag (slag), fly ash and silica fume. The coarse aggregates were either basalt from New South Wales and Victoria, or river gravel or air-cooled blast furnace slag from New South Wales. The mixtures cover a wide range of characteristic compressive strengths from 15 to 90 MPa. Of the three methods commonly used to extrapolate the long-term creep strain, the power model was found to be the most suitable method with good accuracy and a conservative overestimation of the creep strain. Two practical periods of measurement of short-term creep strain, 2-month and one-year, were examined from the 17 sets of medium-term (3-5 years) creep data. Based on the power model, the predicted ultimate creep strain from 2-month creep data tends to overestimate the basic creep factor by an average of 22% compared with measured values at the end of the 3-5 years of testing. Extending the measurement to one-year improves the accuracy with the average overestimation reduced to an average of 15%.

AbstractIn this study 300keV and 1MeV Si vacancy engineering implants have been used to optimise the activation of a 2keV 1×1015cm-2 B implant into SOI. Although the two implants generate a similar areal density of excess vacancies in the SOI top layer, Hall Effect measurements show that low temperature activation is possible to a greater level with the 300keV Si co-implant than with the 1MeV implant. Hall and SIMS data are consistent with a high level of activation of the B at 700°C, with no significant diffusion at the metallurgical junction depth.

A sequential approach to Sparse Component Analysis (SeqTIF) is proposed in this paper. Although SeqTIF employs the estimation process of the simultaneous TIFROM algorithm [1], a source cancellation and deflation technique are also incorporated to sequentially estimate speech signals in the mixture. Results indicate that SeqTIF's separation performance shows a clear improvement upon the simultaneous TIFROM approach, due to the less restrictive assumptions it places upon the signals in the mixture. In particular, the analysis indicates SeqTIF's data efficiency is high, enabling the sequential approach to track a time-varying mixture with much greater accuracy than the simultaneous algorithm. Furthermore, SeqTIF is a more flexible approach, free from the constraints that a simultaneous approach places upon the mixing system.

We propose there are eight essential ingredients for collaboration, regardless of any underlying technology - including face-to-face environments. These ingredients are: two or more people; shared space; time; a common objective; focus on the objective; common language; knowledge in the area of the objective; and interaction. These ingredients are useful for identifying aspects for improvement in both collaboration technology and human collaboration processes. Based on these essential ingredients glimpses of future technology can be seen. © 2005 IEEE.

A computer-controlled treadmill and related data collection and processing systems have been developed for the control of heart rate during treadmill exercise. Minimizing deviations of heart rate from a preset profile is achieved by controlling the speed and/or the gradient of the treadmill. A simple and practical heart rate measurement algorithm has been developed to robustly measure the variations of heart rate. Both conventional proportional-integral-derivative (PID) control and fuzzy proportional-integral (PI) control approaches have been employed for the controller design. The fuzzy proportional-integral algorithm achieved better heart rate tracking performance. Finally, a heart rate based exercising protocol was successfully implemented on the newly designed exercise system

Using four subwoofers, this study investigates horizontal auditory image characteristics for one-third octave bands of pink noise in the frequency range 25 Hz to 100 Hz. The subwoofers were located at 90 degree intervals: 45 degrees to the left and right, and in front of and behind the subject. Single noise bands, coherent pairs, and incoherent pairs were subjectively assessed. Subjects drew the auditory image as an ellipse on a response sheet. Results indicate that left-right discrimination occurs even at the lowest frequencies of human hearing - a finding consistent with other recent research. Image width and depth are correlated, increasing at low frequencies for the stimuli tested, and for simultaneous presentation of coherent or incoherent signals. Like other recently published studies using multiple channels of low frequency sound, this study indicates that multiple subwoofers should be beneficial in multichannel audio systems.

An audio event refers to some specific audio sound which plays important role for video content analysis. In our previous work [3], we have established audio event identification as an audio classification task. Due to the large size of audio database, representative samples are necessary for training the classifier. However, the commonly used random selection of training samples is often not adequate in selecting representative samples. In this paper we present EASIER sampling algorithm to select those data which more efficiently represent audio data characters for audio event identifier training. EASIER deterministically produces a subsample whose "distance" from the complete database is minimal. Experiments in the context of audio event identification show that EASIER outperforms simple random sampling significantly. ©2005 IEEE.

Today's Internet backbone networking devices need to be tested under realistic traffic conditions at transmission rates of OC-48 and above. While commercially available synthetic traffic generators are capable of keeping up with high transmission rates, they fail to produce realistic mixes of flow, packet and address arrival patterns. We explore the alternative of replaying real packet traces from high-speed links using multiple commodity PCs equipped with lower-speed network interfaces. Such an approach is inherently cost-effective because of the use of commodity hardware, and can scale up to any desired transmission rate. We first examine how to split a trace among multiple PCs for the purpose of replaying, and validate our technique using simulations. We use a wavelet 'spectrum' or energy plot for this purpose which enables traffic processes to be viewed simultaneously on many time-scales. Then we present an implementation using Linux PCs with gigabit Ethernet interfaces to replay OC-48 packet traces from the Sprint backbone. Our results show that the replayed trace is very similar to the original trace at most time scales. We are also able to pinpoint the specific system components that contributed to the replay inaccuracy, as well as identify several important challenges that remain to be explored in-depth.

This study attempts to calculate the optimal geometry of convective-radiating radial of ICEs fin arrays using entropy generation method. The analysis is conducted to achieve the balance between entropy generation due to heat transfer and entropy generation due to fluid friction. In designing of the thermal system, it is important to minimize thermal irreversibilities, because the optimal geometry found while the entropy generation rate is minimized. In this study, the entropy generation minimization (EGM) technique based on fin thickness is applied to study the thermodynamic irreversibility caused by heat transfer and fluid irreversibility in radiating convective radial fin arrays. In addition, the cost parameters of fin optimum thickness is also considered and presented. The entropy generation is found to be strongly influenced by emissivity of fin material surface and increasing the cross flow fluid velocity will enhance the heat transfer rate that will reduce the heat transfer irreversibility.

Standard SVM training has O(m 3) time and O(m 2) space complexities, where m is the training set size. In this paper, we scale up kernel methods by exploiting the 'approximateness' in practical SVM implementations. We formulate many kernel methods as equivalent minimum enclosing ball problems in computational geometry, and then obtain provably approximately optimal solutions efficiently with the use of core-sets. Our proposed Core Vector Machine (CVM) algorithm has a time complexity that is linear in m and a space complexity that is independent of m. Experiments on large toy and real-world data sets demonstrate that the CVM is much faster and can handle much larger data sets than existing scale-up methods. In particular, on our PC with only 512M RAM, the CVM with Gaussian kernel can process the checkerboard data set with 1 million points in less than 13 seconds.

In this paper, we extend the recently proposed Core Vector Machine algorithm to the regression setting by generalizing the underlying minimum enclosing ball problem. The resultant Core Vector Regression (CVR) algorithm can be used with any linear/nonlinear kernels and can obtain provably approximately optimal solutions. Its asymptotic time complexity is linear in the number of training patterns m, while its space complexity is independent of m. Experiments show that CVR has comparable performance with SVR, but is much faster and produces much fewer support vectors on very large data sets. It is also successfully applied to large 3D point sets in computer graphics for the modeling of implicit surfaces.

In this study, the lubricant viscosity from a diesel engine operating on various percentages of coconut oil blended fuel is investigated to determine the suitable mixture appropriate for a diesel engine. The coconut oil was blended with conventional diesel fuel at an amount varying from ten to fifty percent. The lubricant used in this study is the conventional commercially available lubricant (SAE 40). After proper blending of diesel with coconut oil, the blended fuels are loaded into the fuel tank. The engine is operated at half throttle setting running at 1600 rpm for 100 hours. At every ten hour interval, one lubricant sample was collected and analyzed using a viscometer at 100 °C and 40 °C. The results show that the viscosity for all the blended fuel remain about constant throughout the 100 hours test. However, fifty percent coconut oil blended fuel at 40 °C shows slightly lower viscosity level in comparison to other percentages of blended fuel system. It is expected this is due to high fuel dilution in lube oil. As a result, ten to thirty percent coconut oil blended fuels seems suitable for diesel engine because it's able to prolong lubricant life span by maintaining its viscosity. Copyright © 2005 by ASME.

Sustainability in its present connotation is a Western concept that has emerged in the West and largely epresents the attitudes of the developed world. Systems in the developing countries are in transition that is further promoted by globalization. They are foreign to sustainability because by definition they are apt to change rather than maintenance, they are either in the release or renewal stages that hardly anybody wishes to sustain, or have just entered the growth stage. Sustainability is enticing for the developed economic systems, which have reached the conservation phase, and would rather endure this stage. In communicating the knowledge of sustainability it is essential to adapt to the local specifics and redefine sustainability accordingly. Local sustainability can be ensured only by borrowing energy, resources and adaptive potential from outside of the system, or by decreasing the sustainability of the global system. Sustainability of a subsystem is achieved at the expense of the supersystem or other subsystems. Therefore institutions that are to maintain life support systems on this planet need to emphasize global priorities and test policies and strategies against the sustainability of the biosphere, rather than regional or local sustainability. We illustrate these ideas with our findings in the Kola Peninsula Russia) and in the Mekong watershed.

The goal of the teledermatology project currently being carried out at Stanford University is to deliver tactile images of the human skin to a dermatologist at a remote location, in real time. In order to make a diagnosis, dermatologists typically need to obtain data regarding the skin texture and the mechanical properties of any lesions on a patient's skin. For example, pre-cancerous or weather-damaged skin typically feels rougher than normal skin and the profile and stiffness of the underlying tissue may shed light on the nature of a skin disease.

With the fast growth of e-commerce, product reviews on the Web have become an important information source for customersý decision making when they plan to buy products online. As the reviews are often too many for customers to go through, how to automatically classify them into different semantic orientations (i.e. recommend/not recommend) has become a research problem. Different from traditional approaches that treat a review as a whole, our approach performs semantic classifications at the sentence level by realizing reviews often contain mixed feelings or opinions. In this approach, a typical feature selection method based on sentence tagging is employed and a naïve bayes classifier is used to create a base classification model, which is then combined with certain heuristic rules for review sentence classification. Experiments show that this approach achieves better results than using general naïve bayes classifiers.

View description>>
Fractal image compression is a relatively recent image compression method which exploits similarities in different parts of the image. The basic idea is to represent an image by fractals and each of which is the fixed point of an Iterated Function System (IFS). Therefore, an input image can be represented by a series of IFS codes rather than pixels. In this way, an impressive compression ratio 10000:1 can be achieved. The application of fractal image compression presented in this paper is based on a novel image structure, Spiral Architecture, which has hexagonal instead of square pixels as the basic element. In the paper evidence would suggest that introducing Spiral Architecture into fractal image compression will improve the compression performance in compression ratio with little suffering in image quality. There are also much research could be done in this area to further improve the results. Copyright © 2005, Australian Computer Society, Inc.

This paper investigates the effects of orientation error in the positioning of triaxial accelerometers on the assessment of energy expenditure. Four subjects walked on a treadmill at varying velocities ranging from 4km.h-1 to 5km.h-1 . During each test, a triaxial accelerometer attached to the lower back at arbitrary orientations to record body accelerations. Energy expenditure was estimated by the sum of the integrals of the absolute value of accelerometer output from all the three measurement directions. Based on theoretical analysis and experimental observations, it is concluded that small orientation errors (<3deg) have no distinguishable effects on the estimation of energy expenditure. We propose an efficient method to compensate for larger orientation errors. The experimental results verified the effectiveness of this proposed compensation method

Precise measurement of expired gas concentrations and volume is required for this determination. For a given gas concentration measurement system, the establishment of a model is a good way to effectively use the equipments and achieve more accurate energy expenditure calculations.

In this paper, we propose a new algorithm for SLAM that makes use of a state vector consisting of quantities that describes the relative locations among features. In contrast to previous relative map strategies, the new state vector is compact and always consists of 2n - 3 elements (in a 2-D environment) where n is the number of features in the map. It is also shown that the information from observations can be transformed and grouped into two parts: first one containing the information about the map and the second one containing the information about the robot location relative to the features in the map. Therefore the SLAM can be decoupled into two processes where mapping uses the first part of the transformed observation vector and localization becomes a 3-dimensional estimation problem. It is also shown that the information matrix of the map is exactly sparse, resulting in potential computational savings when an information filter is used for mapping. The new decoupled SLAM algorithm is called D-SLAM and is illustrated using simulation. © 2005 IEEE.

The systems perspective has been established as a means to structure and understand complex phenomenon. Current approaches are premised on defining and establishing a hierarchical (reductionist) structure that, in effect represents a complex system as a system of systems. The underlying assumption of reductionism is that the resultant component behaviour and dynamics represent the overall system behaviour. In reality, most complex systems and management approaches are highly interconnected, dynamic and subject to non-linear behaviour. As such, they defy any rational description in terms of overall behaviour and effectiveness as prescribed through reductionism. This paper considers the management of major projects as a complex of systems and discusses the nature, characteristics and properties that lead to the difficulties associated with reductionism. The need for systems science, or synthesis, approaches is briefly discussed as an effective means to addressing the situation.

A H-plane sectoral horn antenna made from a woodpile electromagnetic bandgap (EBG) material is described. The electromagnetic confinement mechanism within the horn antenna relies wholly on the 3D EBG of the woodpile material, which is flared in the H-plane. The antenna has a typical sectoral horn pattern with a directional beam in one principal plane and a broader beam in the other. In a prototype antenna, a rectangular waveguide-to-EBG waveguide transition is used to deliver energy to the horn. Preliminary theoretical results on radiation patterns and impedance bandwidth of this antenna are described. The bandwidth of the antenna is almost equal to that of the defect waveguide. © 2005 IEEE.

View description>>
The calibration of catchment modelling systems (CMSs) is regarded as an important part of the modelling process to ensure the reliability and robustness of the parameters. This typically involves minimising an objective function that measures the goodness of fit between observed and simulated hydrographs, with the mean squared error (MSE) objective function being one of the most popular. The focus of this paper is on the assumptions that underlie this objective function, and in particular, on the assumption that the model errors should be independently distributed. Using the US EPA Storm Water Management Model (SWMM) applied to the Powells Creek Catchment in Sydney, Australia as a case study, it is shown that the model errors were autocorrelated for each of the ten historical rainfall/runoff events that were analysed, and that autocorrelation could be removed by fitting a lag-one autoregressive [AR(1)] model to these errors. When examining the influence of the autocorrelated errors on the model performance, however, it was found that the removal of autocorrelation did not result in any observable improvement, and in fact worsened model performance in some cases. The results of this study therefore suggest that caution should be exercised when using an autoregressive model to meet the assumption of independence during model calibration.

View description>>
The concept of frequency de-tuning and damping enhancement to avoid resonant frequencies and to suppress the vibration response of structures, respectively, has been known for passive vibration control systems since mid 1950's. Ideally the concept shifts the structural frequency away from resonant frequency and significantly reduces the structural response in the 'narrow-band' dampingcontrolled region. However in reality, the passive vibration control performance depends heavily on the dynamic characteristics of energy dissipation systems that are fixed and only applicable for a particular frequency band. Conversely, the Direct Current (DC) controllable beam-column semirigid connections using Magneto-rheological (MR) rotational fluid dampers, can act as real time adjustable passive control devices for any required frequency band. The supplied DC current level can adjust the device torque and rotational velocity characteristics that affect the structural frequency. This paper presents a preliminary parametric study on vibration control performance of a single and a two storey prototype plane frame model due to combination of frequency de-tuning and its associated damping enhancement by selecting end beam connections as either hinged or fixed. The controllable semi-rigid connection characteristics are represented in terms of normalised frequency. And the control performance indicated by Amplitude Frequency Characteristics (AFC) of the models is studied numerically and presented graphically.

Edge detection plays an important role in image processing area but is still an open problem. This paper presents a novel edge detection method based on bi-lateral filtering which achieves better performance than single Gaussian filtering. In this form of filtering, both spatial closeness and intensity similarity of pixels are considered in order to preserve important visual cues provided by edges and reduce the sharpness of transitions in intensity values as well. In addition, the edge detection method proposed in this paper is achieved on hexagonally sampled images. Due to the compact and circular nature of the hexagonal lattice, a better quality edge map is obtained on hexagonal architecture than common edge detection on square architecture. Experimental results using our proposed method in this paper exhibit encouraging performance.

Using hexagonal grids to represent digital images have been studied for more than 40 years. Increased processing capabilities of graphic devices and recent improvements in CCD technology have made hexagonal sampling attractive for practical applications and brought new interests on this topic. The hexagonal structure is considered to be preferable to the rectangular structure due to its higher sampling efficiency, consistent connectivity and higher angular resolution and is even proved to be superior to square structure in many applications. Since there is no mature hardware for hexagonal-based image capture and display, square to hexagonal image conversion has to be done before hexagonal-based image processing. Although hexagonal image representation and storage has not yet come to a standard, experiments based on existing hexagonal coordinate systems have never ceased. In this paper, we firstly introduced general reasons that hexagonally sampled images are chosen for research. Then, typical hexagonal coordinates and addressing schemes, as well as hexagonal based image processing and applications, are fully reviewed. © 2005 IEEE.

Web transaction data between Web visitors and Web functionalities usually convey user task-oriented behavior pattern. Mining such type of click-stream data will lead to capture usage pattern information. Nowadays Web usage mining technique has become one of most widely used methods for Web recommendation, which customizes Web content to user-preferred style. Traditional techniques of Web usage mining, such as Web user session or Web page clustering, association rule and frequent navigational path mining can only discover usage pattern explicitly. They, however, cannot reveal the underlying navigational activities and identify the latent relationships that are associated with the patterns among Web users as well as Web pages. In this work, we propose a Web recommendation framework incorporating Web usage mining technique based on Probabilistic Latent Semantic Analysis (PLSA) model. The main advantages of this method are, not only to discover usage-based access pattern, but also to reveal the underlying latent factor as well. With the discovered user access pattern, we then present user more interested content via collaborative recommendation. To validate the effectiveness of proposed approach, we conduct experiments on real world datasets and make comparisons with some existing traditional techniques, The preliminary experimental results demonstrate the usability of the proposed approach. © Springer-Verlag Berlin Heidelberg 2005.

The locality of web pages within a web site is initially determined by the designer's expectation. Web usage mining can discover the patterns in the navigational behaviour of web visitors, in turn, improve web site functionality and service designing by considering users' actual opinion. Conventional web page clustering technique is often utilized to reveal the functional similarity of web pages. However, high-dimensional computation problem will be incurred due to taking user transaction as dimension. In this paper, we propose a new web page grouping approach based on Probabilistic Latent Semantic Analysis (PLSA) model. An iterative algorithm based on maximum likelihood principle is employed to overcome the aforementioned computational shortcoming. The web pages are classified into various groups according to user access patterns. Meanwhile, the semantic latent factors or tasks are characterized by extracting the content of 'dominant' pages related to the factors. We demonstrate the effectiveness of our approach by conducting experiments on real world data sets. © 2005 IEEE.

There has been an increased demand for characterizing user access patterns using web mining techniques since the informative knowledge extracted from web server log files can not only offer benefits for web site structure improvement but also for better understanding of user navigational behavior. In this paper, we present a web usage mining method, which utilize web user usage and page linkage information to capture user access pattern based on Probabilistic Latent Semantic Analysis (PLSA) model. A specific probabilistic model analysis algorithm, EM algorithm, is applied to the integrated usage data to infer the latent semantic factors as well as generate user session clusters for revealing user access patterns. Experiments have been conducted on real world data set to validate the effectiveness of the proposed approach. The results have shown that the presented method is capable of characterizing the latent semantic factors and generating user profile in terms of weighted page vectors, which may reflect the common access interest exhibited by users among same session cluster. © 2005, Australian Computer Society, Inc.

Sensorless permanent magnet synchronous motor (PMSM) drive systems have become very attractive due to their advantages, such as the reduction of hardware complexity and hence the reduced system cost and increased reliability. In order to accurately determine the rotor position required for correct electronic commutation, various methods have been proposed. Among them, the most versatile makes use of the structural and/or magnetic saturation saliencies of the PMSM. This paper presents a non-linear model for PMSMs with the saliencies. The phase inductances of a PMSM are measured and expressed by Fourier series at different rotor positions according to their patterns. The dynamic performance of the PMSM is simulated and compared with that based on a model without considering saliency to verify the effectiveness of the proposed model.

Summary form only given. The (meta) logic underlying classical theory of computation is Boolean (two-valued) logic. Quantum logic was proposed by Birkhoff and von Neumann as a logic of quantum mechanics. It is currently understood as a logic whose truth values are taken from an orthomodular lattice. The major difference between Boolean logic and quantum logic is that the latter does not enjoy distributivity in general. The rapid development of quantum computation in recent years stimulates us to establish a theory of computation based on quantum logic. The present paper is the first step toward such a new theory and it focuses on the simplest models of computation, namely finite automata. We introduce the notion of orthomodular lattice-valued (quantum) automaton. The Kleene theorem about equivalence of regular expressions and finite automata is generalized into quantum logic. We also present a pumping lemma for orthomodular lattice-valued regular languages.

This paper presents a novel robust image stabilization (IS) technique to find out local motion vectors in the image sequences captured. Our technique is based on a Cellular Neural Network (CNN) algorithm, which tracks a small set of features to estimate the motion of the camera. Real-time and parallel analog computing elements are contained in the architecture of CNN. It is a regular two-dimensional array and connects with its neighborhood locally. To implement this algorithm on VLSI CNN, the adaptive-minimized threshold method is proposed to find quickly extract reliable motion vectors in plain images which are lack of features or contain large low-contrast area. Each size of CNN is set to 1/120 of an image. A background evaluation model is also developed to deal with irregular images which contain large moving objects. The experimental results are on-line available to demonstrate the remarkable performance of the proposed CNN-based motion technique.

Web servers rely on edge network devices to perform a number of operations that directly affect the experience of clients and Web services. Distributing Web services across geographic locations owned and configured by third parties is becoming increasingly popular in dealing with high demands. Under the current distributed model, a uniform configuration across all sites is difficult to maintain, resulting in different clients and service experience, which are dependent on the local set-up. In this paper, we propose a model and architecture that enable the owner of a Web service to maintain uniform configuration across all hosting sites. The model enables the administrator of a Web service to write a single configuration script that is then executed on all edge devices at all hosting sites. This is enabled by deploying a new edge device architecture called Serviter. Serviter enables safe sharing of devices through strict partitioning and hardware abstraction thereby facilitating interoperability among vendors.

Programmable network architectures facilitate dynamically updatable functionality to enable selective and trusted third parties on-demand service deployment. Resource and security management of such architectures on shared infrastructure have proven as challenging tasks. This is due to the extent of functionality provided to users and the heterogenous nature of service resource requirements and resource availability. In this paper we present a new programmable network platform that enables safe sharing by providing each trusted user (e.g., an Internet Service Provider) with a secure, separate, and resource assured partition, representing a virtual router, to accommodate their services. To allocate router internal resources among these partitions and among competing services within a partition, this paper uses a new scalable and adaptive mechanism called Control plane-Quality of Service (C-QoS).

In this paper, a novel FDTD method is presented for calculating the dispersion diagram of periodic structures that include lumped passive circuit elements. By combining the FDTD method with periodic boundary conditions (PBCs) and the uniaxial perfect matched layer (UPML), the analysis of periodic structures is reduced to that of a unit cell. The usefulness of the method is demonstrated through the analysis of a negative refractive index material based on a structure that combines lumped and distributed transmission line elements. Numerical results verify the validity of the method. © 2005 IEEE.

Color ratio gradient is an efficient method used for color image retrieval and object recognition, which is shown to be illumination-independent and geometry-insensitive when tested on scenery images. However, color ratio gradient produces unsatisfied matching result while dealing with relatively uniform objects without rich color texture. In addition, performance of color ratio gradient degenerates while processing unsaturated color image objects. In this paper, a scheme with modified color ratio gradient is presented, which addresses the two problems above. Experimental results using the proposed method in this paper exhibit more robust performance.

Human detection is an important research topic for many researchers who are working with surveillance, safe driving, military and security applications. It is now becoming more and more appropriate with the global increase in the terrorism related activities. This paper presents an algorithm for people detection using information gathered from a composite moving sensor incorporating a camera and a laser range finder. Laser range finder is used to identify a region of interest (ROI) where a moving object is likely to be present. Corresponding ROI in the visual image is then analyzed and a hierarchical template matching strategy is used to confirm the presence of a moving human. This approach improves the robustness of the template matching and the computational efficiency as the matching is only done in the resized ROI. The proposed strategy is evaluated through experimentation. © 2005 IEEE.

The interface between concrete and steel in reinforced concrete governs the interaction between the two types of materials under loading. When the interface is seriously damaged, such that a macro-crack is formed, de-bonding takes place or large slip occurs, and the load-transferring capacity of the interface will drop dramatically. In this study, a vibration-based method is presented to detect damage in the reinforced concrete structures using a damage model based on the constitutive law of the lumped model on the concrete-steel interface. Scalar damage parameters characterizing changes in the interface are incorporated into the formulation of a finite element model that is compatible with the vibration-based damage identification procedure. Numerical simulations show that the method is effective to detect failure at the interface between concrete and steel in the reinforced concrete beam.
