Mobile ad hoc networks are data networks entirely made up of enduser communication terminals (known as nodes). Each node in the network can act as an information sink (i.e. a receiver), a source and a router. All nodes have a transmission range, which is limited by their transmission power, attenuation and interference. Mobile ad hoc networks have a number of disadvantages over wired networks. These include limited bandwidth in the wireless medium, limited power supply and mobility. The traditional routing algorithms such as DBF will not work in such networks due to lack of scalability and ability to cope with highly mobile networks. Recently, a number of routing protocols have been designed to overcome these issues. These protocols can be classified into three different categories: global, on-demand and hybrid routing. In this paper, we provide a performance comparison for on-demand routing protocols, which is based on a number of different parameters. This paper also considers which protocol characteristics will produce better performance levels in these networks, and what improvements can be made to further increase the efficiency of some of these routing protocols.

Toughened glass panels used as a glazing material in multistorey buildings are known to fracture prematurely when they contain nickel sulfide inclusions as a result of the phase recrystallisation in nickel sulfide. The kinetics of this recrystallisation were studied by differential scanning calorimetry (DSC) under isothermal and non-isothermal conditions. The recrystallisation was observed to be a two-step process with an induction period followed by the phase change. A two-stage kinetic model was used to estimate the recrystallisation time under ambient conditions. These values were found to correlate well with the observed time to failure for glass panels installed in multistorey buildings.

In the general framework of hydraulic servo systems, this paper addresses the problem of position control in the presence of important friction nonlinearities. The accent falls on the variable structure methodology, as we try to use its intrinsic robustness properties. Several friction observers, including the one based on a variable structure approach, were incorporated and tested in an acceleration feedback control. Next, we present a novel implementation of a variable structure controller, which lumps friction and load as an external disturbance. Results of extensive experimental testing encourage the use of variable structure methods in a class of highly nonlinear hydraulic servo systems

The clinical aggressiveness of neuroblastoma, a childhood embryonal tumour of neuroectodermal cells derived from the neural crest, is considered to be dictated by the competitive interactions between cell proliferation, differentiation and apoptosis. Caspase-9 is a central effector enzyme in the apoptotic mechanism. Recent studies with caspase-9 (CASP9) knockout mice indicate a primary defect in the brain caused by decreased apoptosis during the early stages of nervous system development. It is our hypothesis that silencing of CASP9 through genetic mutations may promote neuroblastoma tumorigenesis. Here, we report the outcome of screening neuroblastoma tumours for silencing mutations in CASP9. cDNA prepared from RNA isolated from 22 neuroblastoma tumours representing the full range of neuroblastoma clinicopathological disease stages was sequenced. Single nucleotide changes were detected in all neuroblastoma tumours, but were found not to represent silencing mutations, but rather sequence polymorphisms. These polymorphisms did not associate with the clinicopathological stages of disease or the predicted clinical outcomes of the patients. Silencing mutations of CASP9 are therefore unlikely to be causal to neuroblastoma tumorigenesis. © 2001 Elsevier Science Ltd. All rights reserved.

Due to the lack of support in mobility and quality of service, today's IP-based networks have some inherent limitations for delivering multimedia services in a mobile environment. In the past few years, these issues have been addressed in the research community and the resulting techniques are being standardised. However, these developments have been done in isolation and become incompatible with each other. In addition to these technical issues, the future infrastructure for charging and accounting mobile multimedia services is expected to be increasingly complicated. In this paper we present a home-proxy based framework which can facilitate the integration of mobility support and QoS management. Furthermore, it enables centralised accounting, which simplifies the cost recovery processes of roaming services. To prove the viability of our design, we have built and tested this framework on a DiffServ wide-area backbone using an MP3 streaming application.

The paper explores an attempt by a small team of staff within the School of Management at the University of Technology Sydney (UTS) to transform the only postgraduate third sector management programme offered in Australia, in response to powerful external and internal pressures for change. After analysing the nature of these contextual imperatives for the transformation of the programme, the paper outlines the rationale underpinning the new programme and the 'intrapreneurial' process that accompanied its implementation. Thereafter, the results of an evaluation of the transformed programme, conducted after the first phase of strategic action, are presented, with specific attention given to an analysis of the politics of its implementation and the nature of the learning gained by the participants in the programme.

View description>>
The wear debris generated from ultra high molecular weight polyethylene (UHMWPE) have been recognised as one of the major causes of failure in total hip replacements (THR). It is essential to reduce the wear debris generated from UHMWPE acetabular cups in order to minimise this problem. Debris in the submicron size range is believed to have greater osteolytic potential. It is now known that crosslinked UHMWPE acetabular cups have reduced volumetric wear rates but little is known about the influence of crosslinking on the size and morphology of the wear debris. In this study, the wear of grade GUR 1020 crosslinked (vacuum gamma irradiated), GUR 1120 crosslinked (acetylene enhanced irradiated) and non cross linked (ethylene oxide sterilised) GUR 1020 UHMWPE was compared in multidirectional pin-on-plate wear tests under three different counterface conditions (smooth, isotropically rough and scratched counterfaces). Multidirectional motion was chosen because this motion was closer to the relative motion in the natural hip. From this study, better wear resistance of crosslinked UHMWPE compared with non-crosslinked UHMWPE was demonstrated for the smooth counterface conditions. However, in the rough and scratched counterface conditions, the vacuum gamma irradiated crosslinked material produced significantly higher wear rates than the non-crosslinked material. The analysis of the wear debris showed that the majority of the volume of the acetylene enhanced crosslinked UHMWPE wear debris was in the most biologically active size range (0.1 to 0.5 microm). In contrast, the non-crosslinked material and the vacuum gamma irradiated crosslinked material had a greater proportion of the volume of the debris in the larger size ranges which are less biologically active. This has important implications for its osteolytic potential.

The effectiveness of a boom is associated with the hydrodynamics in the vicinity of the oil slick that it is attempting to contain, especially under open-sea conditions. A comprehensive investigation of oil containment is provided under various current, wave, and wind conditions. In this paper, a local two-phase nonlinear hydrodynamic numerical model is developed to simulate oil containment by a fixed boom under open-sea conditions. The shape of an oil slick is a function of time, and unstable waves may develop along the oil-water interfacial boundary. This paper describes a simulation of the behavior of the oil slick and deals with important interfacial boundary conditions. A nonhydrostatic pressure is introduced to accommodate the complicated local flow near the oil slick and a successive overrelaxation method is used to solve the pressure equation. A comparison is made of the oil slick shape with and without the hydrostatic pressure assumption. Some simple simulations of free-surface elevations under a number of wave conditions are performed to verify the numerical model. The computed results are in general agreement with those obtained from previous experiments.

In the first of these companion papers, a two-phase numerical model was described and tested for some simple cases under wave conditions. This paper applies that numerical model to simulate the interfacial waves and oil free-surface waves under a number of key hydrodynamic conditions. The characteristics of oil-water interfacial waves and free-surface waves are discussed. Effects of currents and waves on the interfacial waves (interfacial elevation, oil-water relative velocity, and interfacial velocity components) are investigated. The variation of the oil thickness under current and wave conditions is also discussed. The computational results indicate that an increase in the incoming wave height and period may (1) cause instability of the oil-water interfacial waves near the front of the oil slick and this may promote entrainment failure: (2) increase the interfacial waves and free-surface waves at the boom: (3) lower the trough of the oil-water interface at the boom and thus promote drainage failure if the oil thickness exceeds the boom draft; and (4) decrease the freeboard of the boom and thus encourage oversplashing failure.

The numerical simulation of interfacial waves and waves on the free surface of an oil slick under combined current and wave conditions is presented in a companion paper. The present paper focuses on the application of a numerical model developed by Fang and Johnston that numerically predicts the relationship between oil containment failure velocity and wave/wind parameters. Comparative laboratory experiments have been undertaken in a 24-m-long, 0.4-m-wide, 0.4-m-deep wave flume. Detailed comparisons and discussions of the computed and experimental results are provided. The effects of oil viscosity and density on oil containment failure velocity receive particular attention, and the influences of other parameters such as oil volume and boom draft are also quantified. It is concluded that the developed numerical model provides an economic, convenient, and effective method of predicting oil containment failure under various sea conditions.

There is now considerable interest in metal-on-metal bearings for hip prostheses. Extremely low wear rates (0.1 mm3/106 cycles) have been reported in some simulator studies, while in vivo studies, although still very low, have shown wear rates of the order of 1 mm3/106 cycles. The aim of this study was to compare wear rates of metal-on-metal bearings in two hip simulators with different kinematic inputs. In the simulator with three independent input motions which produced an open elliptical wear path with a low level of eccentricity, the wear rates were very low as recorded previously in other simulators. In the simulator with two input motions which produced an open elliptical wear path with greater eccentricity the wear rate was at least ten times higher and closer to clinical values. The motion and kinematic conditions in the contact are critical determinants of wear in metal-on-metal bearings.

Osteolysis and loosening of artificial joints caused by UHMWPE wear debris has prompted renewed interest in metal-on-metal (MOM) hip prostheses. This study investigated the wear and wear debris morphology generated by MOM prostheses in a physiological anatomical hip simulator for different carbon content cobalt chrome alloys. The low carbon pairings demonstrated significantly higher 'bedding in' and steady state wear rates than the mixed and high carbon pairings. The in vitro wear rates reported here were up to one or two orders of magnitude lower than the clinical wear rates for first-generation MOM hip prostheses. Two methods for characterising the metal wear debris were developed, involving digestion, scanning electron microscopy and transmission electron microscopy. The metal wear particles characterised by the two methods were similar in size, 25-36 nm, and comparable to particles isolated from periprosthetic tissues from first and second-generation MOM hip prostheses. Due to the small size of the metal particles, the number of particles generated per year for MOM prostheses in vitro was estimated to be up to 100 times higher than the number of polyethylene particles generated per year in vivo. The volumetric wear rates were affected by the carbon content of the cobalt chrome alloy and the material combinations used. However, particle size and morphology was not affected by method of particle characterisation, the carbon content of the alloy or material combination.

AbstractâThis paper concerns the design of robust control systems using sliding-mode control that incorporates a fuzzy tuning technique. The control law superposes equivalent control, switching control, and fuzzy control. An equivalent control law is first designed using pole placement. Switching control is then added to guarantee that the state reaches the sliding mode in the presence of parameter and disturbance uncertainties. Fuzzy tuning schemes are employed to improve control performance and to reduce chattering in the sliding mode. The practical application of fuzzy logic is proposed here as a computational-intelligence approach to engineering problems associated with sliding-mode controllers. The proposed method can have a number of industrial applications including the joint control of a hydraulically actuated mini-excavator as presented in this paper. The control hardware is described together with simulated and experimental results. High performance and attenuated chatter are achieved. The results obtained verify the validity of the proposed control approach to dynamic systems characterized by severe uncertainties.

Common approaches in practice to predict underground explosion-induced stress wave intensity are based on some empirical formulae. Those empirical formulae were obtained by different researchers based on their testing data at various sites. They can predict the peak particle velocities (PPV) and / or peak particle accelerations (PPA) of propagating stress wave at various locations. They usually include the effect of explosion loading density in terms of a decoupling factor, but do not take into consideration the effects of other explosion conditions, such as the charge chamber geometry, explosive location and distribution. In this paper, a previously calibrated numerical model is used to perform parametric calculations to investigate the effects of underground explosion conditions on stress wave propagation and damage at a granite site. Based on the numerical results, some formulae, which include the effects of various explosion conditions, are derived to predict peak particle acceleration (PPA), peak particle velocity (PPV) and principal frequency of stress wave in the granite mass. The proposed formulae are also compared with the empirical formulae obtained from blasting tests conducted at the site under consideration.

In this paper a number of serviceability issues related mainly to excessive deflections of structural floor elements (beams and slabs) are discussed. Field data of serviceability damage caused by excessive deflections of structural floor elements have been collected from various sources and probabilistic models are developed. Current serviceability specifications for allowable deflection limits in Australian, U.S., and other concrete structure codes have been compared against these probabilistic distributions of damaging deflections. Preliminary results confirm that allowable deflection limits in these design codes represent realistic lower-bound values of damaging deflections.

AbstractThis study isolated and characterized UHMWPE particles from 3 explant groups: early Charnley hip failures (ECE; < 10 years), late Charnley hip failures (LCE; > 10 years) and early knee failures (EKE; < 10 years). Debris isolated from the 3 groups had percentage particle number and percentage volumetric concentration distributions that were not significantly different. The greatest number of particles were found in the 0.1–0.5 μm size range and 19–20.6% of the volumetric concentration was below 1 μm in size in all groups. However, there were significant differences in the total volumetric concentration of debris isolated per g of tissue. LCE had significantly higher volumes of debris than ECE and EKE, there was no significant difference in the volume of debris from the EKE and ECE. The mean aspect ratio and mean irregularity ratio of the LCE group were also significantly higher than the ECE and EKE, suggesting that different wear mechanisms were occurring in the late Charnley group compared to the early Charnley and knee groups. These results also suggest that early knees, with normal surface wear, may have similar wear mechanisms to early Charnley hips and indicate that similar volumes of biologically active micrometer and sub‐micrometer UHMWPE particles were produced. This may have important implications in the longer‐term outcome of total knee arthroplasties, because it indicates a similar potential for osteolysis induced by wear debris. © 2001 John Wiley & Sons, Inc.

This paper considers the problem of local stabilization of uncertain continuous-time systems with time-delay and saturating actuators. A new closed-loop stability theorem based on the Lyapunov-Krasovskii stability theorem is obtained. Moreover, two methods are given to design a state feedback controller such that the stability region of the resultant closed-loop system is enlarged. Both the controller and the bound of the safe initial conditions can be obtained by solving LMI problems. Numerical examples are employed to demonstrate the effectiveness of the proposed techniques.

Leptines of Solanum chacoense are effective natural deterrents against the Colorado potato beetle. Leptines are the acetylated forms of the glycoalkaloids solanine and chaconine and are supposed to be synthesised via hydroxylated derivatives, called leptinines. Inheritance of leptinine production was studied in crosses of closely related S. chacoense genotypes. The segregation data supported a single-gene model for the inheritance of leptinine production. In the segregating F1 population of a S. chacoense cross, AFLP, RFLP and RAPD markers segregating with the leptinine production have been identified. The locus involved in leptinine synthesis was localised to the short arm of chromosome 1 of the potato where a major QTL for solanidine production, and markers with tight linkage to leptine production, have been mapped before. Our data further support the previous finding that the short arm of chromosome 1 is involved in steroid alkaloid synthesis in potato, and suggest that the genes involved in leptinine and leptine production are tightly linked in S. chacoense.

The 21-nucleotide small temporal RNA (stRNA) let-7 regulates developmental timing in Caenorhabditis elegans and probably in other bilateral animals. We present in vivo and in vitro evidence that in Drosophila melanogaster a developmentally regulated precursor RNA is cleaved by an RNA interference-like mechanism to produce mature let-7 stRNA. Targeted destruction in cultured human cells of the messenger RNA encoding the enzyme Dicer, which acts in the RNA interference pathway, leads to accumulation of the let-7 precursor. Thus, the RNA interference and stRNA pathways intersect. Both pathways require the RNA-processing enzyme Dicer to produce the active small-RNA component that represses gene expression.

The shear behaviour of bolted and non-bolted joints containing infill material was studied under the constant normal stiffness condition. More than 40 sawtooth-shaped samples having an asperity angle of 18·5° were tested. The shear behaviour of bolted and non-bolted joints containing infill material, up to 7·5 mm in thickness, was studied under various initial normal stress levels between 0·13 and 3·25 MPa, at a constant strain rate of 0·5 mm/min and a constant stiffness of 8·5 kN/mm. Significant reduction in shear strength was observed when the joint contained a layer of clay infill of 1·5 mm. Bolting contributed to increasing the strength and stiffness of the joint composite, except at large normal stress levels and at high infill thickness. The dilation and overall friction angle for bolted and non-bolted joints were also compared along with stress profiles. At high infill thickness, the shear behaviour under both constant normal load (CNL) and constant normal stiffness (CNS) conditions was found to be similar for both bolted and non-bolted joints, while at low infill thickness the CNL strength envelope plotted significantly above the CNS envelope.

Oxidation of sulphide minerals in acid sulphate soils has acidified a substantial part of the low-lying coastal land in Australia. Such sulphides, including pyrite (FeS 2 ) formed thousands of years ago during saline inundation of soils rich in iron. They do not pose a serious concern when submerged by the water table, because this prevents atmospheric oxygen reacting with the pyritic layer. However, flood protection of low-lying coastal land through the installation of deep surface drains has caused a general lowering of the water table elevation, that in turn has exposed the pyritic layers to atmospheric oxygen. High rainfall following droughts causes acid pollution of the surrounding flood mitigation drains, creeks and river systems. Large ground areas are affected by the transport of acid constituents during seepage. One way of controlling new acid production is through the installation of weirs in the flood mitigation drains in order to raise the water table elevation. In this paper, the acid pollution in New South Wales is reviewed, and the effect of groundwater elevation is examined. Relationship between acid production and groundwater table is examined. Mathematical models are developed to simulate acid production and transport, and two groundwater management regimes are examined. Weir based control of the groundwater table is shown to be successful in controlling acid production.

It is well known that saddle-node bifurcations can occur in the steady-state response of a forced single-degree-of-freedom (SDOF) nonlinear system in the cases of primary and superharmonic resonances. This discontinuous or catastrophic bifurcation can lead to jump and hysteresis phenomena, where at a certain interval of the control parameter, two stable attractors exist with an unstable one in between. A feedback control law is designed to control the saddle-node bifurcations taking place in the resonance response, thus removing or delaying the occurrence of jump and hysteresis phenomena. The structure of candidate feedback control law is determined by analyzing the eigenvalues of the modulation equations. It is shown that three types of feedback - linear, nonlinear, and a combination of linear and nonlinear - are adequate for the bifurcation control. Finally, numerical simulations are performed to verify the effectiveness of the proposed feedback control.

The non-linear response of a rotor supported by active magnetic bearings is investigated, and both primary and internal resonances are considered. The method of multiple scales is used to obtain four first order ordinary differential equations that describe the modulation of the amplitudes and phases of vibrations in the horizontal and vertical directions. The steady state response and the stability of the solutions are determined numerically from the reduced system. It is shown that the steady state solutions lose their stability by either saddle-node bifurcation or Hopf bifurcation. In the regime of multiple coexisting solutions, two stable solutions are found. The effect of imbalance eccentricity, as well as the effect of the proportional and derivative gains of the controller on the non-linear response of the system, are studied. Finally, numerical simulations are performed to verify the analytical predictions.

View description>>
Gene expression and regulation may be viewed as a parallel parsing algorithm---translation from a genomic language to a phenotype. We describe a model of gene expression and regulation based on the operon model of Jacob and Monod. Operons are groups of genes regulated in the same way. An artificial cellular metabolism expresses operons encoded on a genome in a parallel genomic language. This is accomplished using an abstract entity called a spider. A genetic algorithm is used to evolve the simulated cells to adapt to a simple environment. Genomes are subjected to recombination, mutation, and inversion operators. Observations from this experiment suggest four areas to explore: dynamic environments for the evolution of regulation, advantages of time lags inherent in the expression algorithm, sensitivity of our genomic language, and noncoding regions on the genome. Issues relating to the application of the expression model to evolutionary computation are discussed.

This paper presents a procedure for the probabilistic analysis of time-dependent deflection of a reinforced concrete flexural member subject to a time-varying load process. Particular consideration is given to simply supported, singly reinforced rectangular beams. The algorithm takes into account concrete maturation, nonlinear creep and shrinkage behavior, and stochastic load process models for both construction and service. While this paper describes some practical implications of early-age effects (i.e., high early-age construction loads on immature concrete) for serviceability design, the emphasis of this paper is on the probabilistic time-dependent deflection analysis technique. © 2001 Elsevier Science Ltd.

We report the identification, cloning and tissue distributions of ten novel human genes encoding G protein-coupled receptors (GPCRs) GPR78, GPR80, GPR81, GPR82, GPR93, GPR94, GPR95, GPR101, GPR102, GPR103 and a pseudogene, ψGPR79. Each novel orphan GPCR (oGPCR) gene was discovered using customized searches of the GenBank high-throughput genomic sequences database with previously known GPCR-encoding sequences. The expressed genes can now be used in assays to determine endogenous and pharmacological ligands. GPR78 shared highest identity with the oGPCR gene GPR26 (56% identity in the transmembrane (TM) regions). ψGPR79 shared highest sequence identity with the P2Y2 gene and contained a frame-shift truncating the encoded receptor in TM5, demonstrating a pseudogene. GPR80 shared highest identity with the P2Y1 gene (45% in the TM regions), while GPR81, GPR82 and GPR93 shared TM identities with the oGPCR genes HM74 (70%), GPR17 (30%) and P2Y5 (40%), respectively. Two other novel GPCR genes, GPR94 and GPR95, encoded a subfamily with the genes encoding the UDP-glucose and P2Y12 receptors (sharing >50% identities in the TM regions). GPR101 demonstrated only distant identities with other GPCR genes and GPR102 shared identities with GPR57, GPR58 and PNR (35-42% in the TM regions). GPR103 shared identities with the neuropeptide FF 2, neuropeptide Y2 and galanin GalR1 receptors (34-38% in the TM regions). Northern analyses revealed GPR78 mRNA expression in the pituitary and placenta and GPR81 expression in the pituitary. A search of the GenBank databases with the GPR82 sequence retrieved an identical sequence in an expressed sequence tag (EST) partially encoding GPR82 from human colonic tissue. The GPR93 sequence retrieved an identical, human EST sequence from human primary tonsil B-cells and an EST partially encoding mouse GPR93 from small intestinal tissue. GPR94 was expressed in the frontal cortex, caudate putamen and thalamus of brain while GPR95 was expressed in the huma...

This paper presents the dynamic modelling and energy-optimal motion planning of a hybrid legged-wheeled mobile vehicle. The equations describing the dynamic behaviour of such vehicles are complex. Kane's method and the Autolev symbolic manipulation package was used in the dynamic modelling. A state parameterization method is used to synthesize the leg trajectories for the hybrid vehicle. The resulting energy-optimal gait is experimentally evaluated to show the effectiveness and feasibility of the path planned.

One important purpose of conducting gene expression experiments is to understand the correlation of gene expression profiles to disease states. Based on the notion of emerging patterns and an entropy-oriented discretization method, we discover groups of genes that are correlated to disease states in a significant way. In each group, every member gene constrained by a specific expression interval, unanimously occurs only in one type of cells with a maximally large frequency, but never unanimously happens in the other types of cells. According to our studies on the colon tumor dataset, such gene groups (also called patterns) can reach a frequency of 90%, providing good insight into the correlation of gene expression profiles to disease states. The patterns can be used to correctly predict whether a new cell is normal or cancerous.

Ingestion of soils with high flouride (F) concentration may cause chronic flourosis in grazing animals. Analysis of New Zealand pasture solis with long-term phosphorus (P) fertilisation histories showed that the total surface soil (0-75 mm depth) F concentration increased up to 217-454 mg kg-1 with P fertiliser application. One-third to two-thirds of F applied in fertilisers resides in the top 75 mm soil depth. Pasture forage accumulation of F was low, and therefore, F intake by grazing animals through pasture consumption is expected to be much lower than F intake by soil ingestion. Ten annual applications of single superphosphate (30 and 60 kg P ha-1 year-1) to a Palllic Soil (Aeric Fragiaqualf) significantly increased total F and labile F (0.01 M CaCl2 extract) concentrations to 200 and 120 mm depths, respectively, of the 300 mm depth investigated. The mobility of F in the soil profile was similar to two other elements, P and cadmium derived fom the fertiliser. © 2001 Elsevier Science Ltd. All rights reserved.

Linear prediction (LP) is the cornerstone of most modern speech compression algorithms. Previously it has been shown that incorporating a weighting function based on the simultaneous masking property of the ear into the calculation of the LP coefficients (SMWLPC) allows the filter to better model the unmasked sections of the input spectrum. This paper conducts a detailed analysis of the implementation of SMWLPC in low rate speech codecs. The analysis allows the cause of inconsistencies in the technique to be identified and solutions formulated. Experimental results show that when combined with the proposed changes, the SMWLPC technique is suitable for implementation in any low rate LP based speech codec and the net result is an improvement in the perceptual quality of synthesised speech for all speakers.

The method is based on the hypothesis that the warping displacement of a flange plate is governed by a third-order parabolic curve. Based on the principle of minimum potential energy, the governing differential equations with two unknown displacement functions are derived. The homogeneous solutions of the differential equations are used to represent the displacement functions of the finite element. By mean of the variational principle, the element stiffness equation is developed and the normal longitudinal stresses taking into account the shear lag are obtained. To verify the accuracy of the proposed method, three experiments are conducted so that the present results are compared with those obtained by the model tests and other methods.

Dynamometer tests have been carried out to evaluate the performance, emissions and wear characteristics of an indirect injection diesel engine when fuelled by 10, 20, 30, 40 and 50 per cent blends of ordinary coconut oil (COCO) with ordinary diesel fuel (OD). The test was conducted for 100 h using each of the test fuels to monitor the effect of COCO blends on the wear and lubricating oil performance. OD fuel was also used for comparison purposes. The operating performance of the engine and the emission characteristics of exhaust gases were compared. The effect of blended fuel on the engin's wear and lubrication characteristics in terms of wear metal (Fe), water concentration, oxidation, viscosity, total base number and additive depletion was analysed. The performance and emissions characteristics results showed that 10-30 per cent coconut oil blends produced slightly higher performance in terms of brake power than OD. All the COCO blends produced lower exhaust emissions including polycyclic aromatic hydrocarbons and particulate matter. The wear and lubrication oil characteristics results showed that COCO blends up to 30 per cent produced similar results to OD. This programme will give useful information for further research and development in the future if COCO is used as an alternative to OD.

Background and Purpose —Tumor necrosis factor-α (TNF-α) expression is increased in brain after cerebral ischemia, although little is known about its abundance and role in intracerebral hemorrhage (ICH). A TNF-α–specific antisense oligodeoxynucleotide (ORF4-PE) was used to study the extent to which TNF-α expression influenced neurobehavioral outcomes and brain damage in a collagenase-induced ICH model in rat. Methods —Male Sprague-Dawley rats were anesthetized, and ICH was induced by intrastriatal administration of heparin and collagenase. Immediately before or 3 hours after ICH induction, ORF4-PE was administered directly into the site of ICH. TNF-α mRNA and protein levels were measured by reverse transcriptase–polymerase chain reaction and immunoblot analyses. Cell death was measured by terminal deoxynucleotidyl transferase–mediated uridine 5′triphosphate-biotin nick end labeling (TUNEL). Neurobehavioral deficits were measured for 4 weeks after ICH. Results —ICH induction (n=6) elevated TNF-α mRNA and protein levels ( P <0.01) at 24 hours after the onset of injury compared with sham controls (n=6). Immunohistochemical labeling indicated that ICH was accompanied by elevated expression of TNF-α in neutrophils, macrophages, and microglia. Administration of ORF4-PE (2.0 nmol) directly into striatal parenchyma, 15 minutes before (n=4) or 3 hours after (n=6) ICH, decreased levels of TNF-α mRNA ( P <0.001) and protein ( P <0.01) in the brain tissue surrounding the hematoma compared with animals treated with saline alone (n=6). Mean±SEM striatal cell death (cells pe...

This letter presents a near-far resistant detection scheme for asynchronous code-division multiple access with frequency offset. Based on a one-shot technique and Taylor expansion, a zeroth-order and a first-order one-shot linear decorrelating detector (LDD) are proposed. The zeroth-order LDD has simple architecture but suffers performance degradation for large frequency offset. The first-order one-shot LDD, with increased complexity, has very good near-far resistant property even for large frequency offset. Two versions of the first-order one-shot LDD are investigated according to different Taylor expansion approaches. The feasibility of the proposed detectors is demonstrated by computer simulations.

Abstract Fractures of the proximal humerus, forearm, and wrist account for approximately one third of total osteoporotic fractures in the elderly. Several risk factors for these fractures were evaluated in this prospective study of 739 men and 1,105 women aged ≥60 years in Dubbo, Australia. During follow-up (1989–1996), the respective incidences of humerus and of forearm and wrist fractures, per 10,000 person-years, were 22.6 and 33.8 for men and 54.8 and 124.6 for women. Independent predictors of humerus fracture were femoral neck bone mineral density (FNBMD) (relative risk (RR) = 2.3, 95% confidence interval (CI): 1.2, 4.5) in men and FNBMD (RR = 2.4, 95% CI: 1.7, 3.5) and height loss (RR = 1.1, 95% CI: 1.0, 1.2) in women. For forearm and wrist fractures, risk factors were FNBMD (men: RR = 1.5, 95% CI: 1.0, 2.3; women: RR = 1.5, 95% CI: 1.2, 1.9) and height loss (men: RR = 1.2, 95% CI: 1.0, 1.3; women: RR = 1.1, 95% CI: 1.0, 1.2). In addition, dietary calcium (men: RR = 2.0, 95% CI: 1.0, 3.6) and a history of falls (women: RR = 1.9, 95% CI: 1.4, 2.6) were also significant. These data suggest that elderly men and women largely share common risk factors for upper limb fractures and that FNBMD is the primary risk factor.

We have previously reported a strong correlation between poor prognosis in childhood neuroblastoma (NB) patients and high-level expression of the transmembrane efflux pump, Multidrug Resistance-associated Protein (MRP1), in NB tumour tissue. In this study, we inhibited the endogenous expression of MRP1 in 2 different NB tumour cell lines by stably transfecting an MRP1 antisense expression vector (MRP-AS). Compared with control cells, MRP-AS transfectant cells demonstrated a higher proportion of dead and morphologically apoptotic cells, spontaneous neuritogenesis, and, increased synaptophysin and neurofilament expression. Bcl-2 protein expression was markedly reduced in MRP-AS cells compared to controls. Conversely, we found that the same NB tumour cell line overexpressing the full-length MRP1 cDNA in sense orientation (MRP-S) demonstrated resistance to the neuritogenic effect of the differentiating agent, all-trans-retinoic acid. Taken together, the results suggest that the level of MRP1 expression in NB tumour cells may influence the capacity of NB cells for spontaneous regression in vivo through cell differentiation and death. © 2001 Cancer Research Campaign.

AbstractPlanar photonic bandgap structures have been modeled using the theory of transmission lines and periodic circuits. The method allows for fast and accurate computation of the dispersion diagram, and thus prediction of the stopbands for two directions of propagation. Results obtained by the proposed analytic method are in agreement with previously published numerical data for two structures. Additional numerical evaluations of the reflection phase with the finite‐difference time‐domain (FDTD) method confirm the validity of the analytic model within the limits of its applicability. They also further confirm previous observations that wave propagation in directions other than two principal axes results in a narrower stopband. © 2001 John Wiley & Sons, Inc.

In this paper, we present new results on Temporal Decomposition (TD) applied to the Line Spectral Frequencies (LSFs) derived for wideband speech. The paper shows that by incorporating a dynamic programming search algorithm into TD, near transparent quantisation of wideband LSFs can be obtained at approximately 1 kbps. We also show that TD performs significantly better than Split Vector Quantisation at low bit rates. We propose that TD is a promising approach to low rate wideband speech coding for applications such as unicast streaming.

This paper develops a probabilistic construction load process model for multistory reinforced-concrete building construction. This model considers loads causing peak structural actions on floor slabs for two widely used shoring procedures and includes probability distributions and temporal characteristics of slab self-weight, sustained construction live loads, 'material stacking' loads, and 'move-in' loads. Construction load statistics derived from Monte Carlo simulation show that the mean of maximum construction loads exceeds nominal (design) service (occupancy) loads whenever the nominal live-to-dead load ratio is less than approximately 1.0. A Type I extreme value distribution provided the best fit to the inferred distributions of construction live loads.

Abstract A 51 year old man presented with a two year history of gradually deteriorating vision in his left eye, accompanied by 34 kg weight gain, easy bruising, and hypertension which was relatively resistant to conventional treatment. The patient denied any history of headaches. On examination, his general appearance was as shown (fig 1). On ocular examination his visual acuity was 6/6 in the right and 6/12 in the left eye. A left relative afferent pupillary defect was present and fundoscopically there was left optic nerve atrophy. Numerous investigations were performed, including Humphrey's field analysis (fig 2), and a cerebral magnetic resonance imaging (MRI) scan (fig 3). Eye positions on left lateral gaze were as shown (fig 4).

This paper investigates the performance of various load-stepping schemes for finite element analysis with critical state soil models. The accuracy of simple incremental schemes is found to be strongly influenced by the load increment size, the type of flow rule, and the overconsolidation ratio. Similarly, these factors are shown to have a pronounced effect on the efficiency and stability of some classical iterative schemes. Unless they are performed with small load steps, critical state analyses with fixed increment sizes frequently exhibit non-convergent behaviour or lead to inaccurate solutions. The automatic incrementation schemes developed by Abbo and Sloan (International Journal for Numerical Methods in Engineering 1996; 39: 1737-1759; Proceedings of 5th International Conference, Owen DRJ, Onate E, Hinton E. International Center for Numerical Methods in Engineering, Barcelona, 1997; 1:325-333), which are based on standard methods for integrating systems of ordinary differential equations, are shown to be efficient, accurate and robust solution techniques for a wide variety of critical state problems. © 2001 John Wiley & Sons, Ltd.

Advanced collaborative display systems allow users to view a computing 'desktop' environment in a platform and location independent fashion. For real-time considerations, these systems become computationally very challenging, especially when video-streaming is included. The addition of stereoscopic video streaming is desirable in Virtual Environments (VE) created for the teaching of anatomy and surgery with real-time collaborative audio and video interactions at many locations. However this stresses the real-time requirements to the point at which realistic video is difficult to assure. For such a system to work, it is imperative that timing data be collected, analyzed, and understood. In this paper, we describe an experimental system designed primarily for collection of timing data required for robust collaborative medical training applications. The networked stereoscopic system uses a server-swappable multicast network protocol to stream real-time manipulations of 3D Virtual Body Structures (VBS) at th e server site to all clients participating in the multicast session. The three visual modes (mono, psa, and asi) have dynamic tuning parameters for adjusting the parallax and the focal point for the rendered scene, allowing users to define individual stereoscopic comfort zones. Our main result demonstrates that optimizing the graphics module is critical in achieving the necessary rendering rates. Different techniques of utilizing various memory resources increased the number of polygons rendered per second by over seven million. Depending on the type of memory used the number of polygons rendered per second varies from 2.25 to 9.12 million.

For existing structures, information about 'safe' past performance (such as prior load history) may be used to update the probability distribution of resistance and hence reliability. This technical note investigates the effect of realistic construction loading with sustained dead and live loads and extraordinary live loads on time-dependent probabilities of failure. Structural configurations considered include RC floor beams and slabs designed to ACI 318, for various live-to-dead load ratios and construction periods for typical RC multistory buildings. The results show, for example, that the probability of failure for an existing structure after 5-10 years of occupancy is one or more orders of magnitude lower than that prior to the application of construction loads. This suggests that, if a structure survives construction and early service (occupancy) loads, then its reliability is increased significantly. Finally, for cases where prior service live loads are unknown, the inclusion of construction dead loads alone will still lead to significant increases in structural reliability.

Information about present and anticipated bridge reliabilities, in conjunction with decision models, provides a rational and powerful decision-making tool for the structural assessment of bridges. For assessment purposes, an updated reliability (after an inspection) may be used for comparative or relative risk purposes. This may include the prioritisation of risk management measures (risk ranking) for inspection, maintenance, repair or replacement. A life-cycle cost analysis may also be used to quantify the expected cost of a decision. The present paper will present a broad overview of the concepts, methodology and immediate applications of risk-based assessments of bridges. In particular, two practical applications of reliability-based bridge assessment are considered - risk ranking and life-cycle cost analysis. © 2001 Elsevier Science Ltd. All rights reserved.

Sanitation and wastewater management problems in small and medium towns in India (referred to as “semi-urban areas” - SUAs) are distinctly different from those of large cities or rural villages. There is an apparent lack of choices of appropriate sanitation options for these semi-urban areas, leading them to adopt on-site sanitation technologies. A field study of four such small towns in India was conducted to evaluate the suitability of available low-cost wastewater collection and treatment technologies, in light of their current practice. Based on the field study, this paper suggests a system comprising “combined surface sewers” and “reed-bed channel” for collection and treatment of wastewater for semi-urban areas, that can utilize all the existing infrastructure to effect better sanitation at lower costs. The suggested system involves converting the existing open wastewater collection drains on the road sides, as “decentralized” networks of covered drains with simple structural modifications to collect both wastewater and stormwater; and, converting the large open drains on the outskirts of SUAs that carry wastewater to agricultural fields, as gravel media filled beds planted with local reeds. Cost estimates for the towns studied indicate this system to be over 70% cheaper compared to conventional collection and treatment systems.

The degradation of poly(vinyl alcohol) was investigated using TG analysis and Fourier transform infrared spectroscopy to determine the effect of atmosphere on the process of degradation. In the spectra, four vibrational modes were identified that characterised the major steps of the degradation process. These were the O-H, C-H, C=O and C=C stretching modes. The mechanism observed for degradation in an inert atmosphere was in accordance with the accepted mechanism of elimination followed by pyrolisation. Evidence of conjugated polyenes, however, was not observed. For the air atmosphere, oxidation in both steps of the degradation process was observed.

View description>>
Detailed analyses of acid sulphate soils in coastal areas of Berry (New South Wales, NSW) indicate that pyrite (FeS2) oxidation generally occurs very close to narrow root channels. The root channels have been caused by extant organic activity and allow oxygen to diffuse through to the pyritic layers. From the wall of the root channels in the pyritic layers, oxygen diffuses laterally into the acid soil matrix, oxidizing the pyrite present. Such a simultaneous process can be modeled cylindrically. In this paper, a new cylindrical model is developed and solved using approximations to pyrite consumption kinetics. An adapted PDE2D code based on finite element methods is used to solve a linear approximation and Michaelis-Menten uptake kinetics. Pyrite oxidation produces acid in the soil 'matrix that is subsequently transported to the estuarine waterways, following high rainfall sessions causing a number of environmental disasters. An estimate of the new acid produced in the field is often required before remediation work is possible, and such an estimate may be determined easily using the new model. The results of pyrite oxidation based on the cylindrical approach demonstrate that the new model can accurately predict pyrite oxidation and acid production. The total acid production calculated using the new approach was found to be close to the actual field amount at the Berry site. The new results also compare well with the predictions made by previous models developed for the Berry site.

View description>>
In this paper, we propose a systematic and theoretically sound way to design a global optimal fuzzy tracking controller for discrete-time fuzzy systems with the aim of solving the discrete-time quadratic tracking problems with moving or model-following targets under finite or infinite horizon (time). A linear-like dynamical system representation of discrete-time fuzzy system is proposed to mature the theoretical design scheme of the discrete-time optimal fuzzy tracking controller which can achieve global minimum effect. A multistage decomposition of optimization scheme is proposed to simplify the computation, and then a segmental recursive Riccati-like equation and a difference equation in tracing the variation of the target are derived. Moreover, in the case of time-invariant fuzzy tracking systems, we show that the optimal tracking controller can be obtained by just solving discrete-time algebraic Riccati-like equations and algebraic matrix equations. An example is given to illustrate the proposed opti mal fuzzy tracker design scheme.

Samples of sub-surface water, suspended particulate matter (SPM) and surface sediments collected from Daya Bay, China have been analysed for 12 polychlorinated biphenyl (PCB) congeners and 18 organochlorine insecticides, using gas chromatography electron capture detection. Total PCB levels varied from 91.1 to 1355.3 ng l-1 in water and from 0.85 to 27.37 ng g-1 dry weight in sediments. The levels of total organochlorine insecticides were in the range 143.3-5104.8 ng l-1 in water and 2.43-86.25 ng g-1 dry weight in sediment. None of the target compounds were detected in SPM. The levels of total hexachlorocyclohexanes in water varied from 35.5 to 1228.6 ng l-1, whilst in sediments they ranged from 0.32 to 4.16 ng g-1 dry weight. For the sum of dichlorodiphenyltrichloroethanes (DDTs), their levels were in the range 26.8-975.9 ng l-1 in water, and 0.14-20.27 ng g-1 dry weight in sediments. The distribution profiles of these contaminants in water and sediments suggest that there are a number of sources contributing to total contaminant burden in the bay, including soil runoffs, wastewater discharges, sewage outfalls and shipping activities. Ratios of DDT/(DDE+DDD) in the water and sediments indicate recent inputs of such chemicals into the bay. The results, therefore, provide important information on the current contamination status of a key aquacultural area in China, and point to the need for urgent actions to stop the use of persistent agrochemicals such as DDT and lindane.

The concentrations of Hg, Sn, Cr, Zn, Ni, Co, Cd, Mn, Fe and Cu were determined in the liver, kidney and muscle of 24 common dolphins stranded on the Portuguese coast between 1995 and 1998. Nitric acid was used to extract the metals from the tissues for analysis by inductively-coupled plasma/atomic emission spectroscopy (ICP/AES). Those metals with relatively higher concentrations included Fe, Zn and Hg, particularly in liver. Other metals including Cr, Ni and Cd tended to show much lower levels, or were even undetected (e.g. Co). Different metals seemed to show different temporal trends, although due to substantial variations of the mean concentrations for each year obtained, such temporal pattern has to be studied further. Total Hg concentration in the kidney, muscle and particularly liver, were higher in females than in males. Total Hg concentrations in all the organs increased with body length of dolphins, whilst those of Zn and Cu in muscle decreased with dolphin length. A strong correlation was found between essential metals Zn and Cu in muscle, possibly resulting from sequestration of these metals by metallothionein. In addition, significant co-associations existed between the same metal (e.g. Hg, Sn and Zn) in different organs. © 2001 Elsevier Science B.V.

A method is presented to identify indirectly loads moving on an orthotropic plate. The loads are in a group of two forces or four forces. The dynamic behavior of the plate under the action of these moving loads is analyzed. A method to identify these moving forces from the dynamic responses of the plate is developed basing on the modal superposition principle, and Tikhonov regularization procedure is applied to provide bounds to the solution in the time domain. Prior knowledge on the modal properties of the plate and the velocity of loads is required. The errors in the identified individual loads are discussed. The effect of different combinations of measuring locations on the identification is studied. Numerical results show that acceleration responses would give better and acceptable results than strain measurements.

Phosphorus deficiency is a major problem affecting tea production in the highly weathered acid soils of humid and sub-humid tropics which are known to have high P fixing capacities. As many of these soils are strongly acidic and receive high rainfall, low-cost phosphate rock (PR) may effectively supply the plant P needs and limited preliminary experiments suggest this is so. A long-term glasshouse trial was conducted on 8-month old tea seedlings to compare the agronomic effectiveness of a locally available PR (Eppawala phosphate rock, EPR) with triple superphosphate (TSP) applied to a strongly acidic (pH water 4.55) marginally P deficient Rhodustult from Sri Lanka at six rates ranging from 10 to 60 kg P ha-1. The results showed that TSP or EPR fertiliser at a rate as low as 10 or 20 kg P ha-1 was sufficient to obtain maximun tea yield. The agronomic effectiveness of EPR was equal to that of TSP at the 5- and 10-month samplings. The concentration of soil P extracted by a cation-anion exchange resin membrane (resin-P) was higher in the TSP treated soil at 5 months due to its greater solubility but at 10 months, the EPR produced higher resin-P due to its increased dissolution over time. In the presence of tea plants, 52% of P from the EPR applied at the rate of 10 kg ha-1, was dissolved at 5 months compared to 75% of dissolution at the 10-month sampling. In the absence of plants, the corresponding dissolution figures were 40% at 5 months and 55% at 10 months. The concentration of inorganic P extracted by 0.1 M NaOH (NaOH-Pi) (loosely characterising Fe + Al bound P) was significantly higher in the TSP treated soil and concentration of P extracted by 0.5 M H2SO4 (Ca bound P) was higher in the EPR treated soil. The results suggest that the low-cost, locally available EPR may be used profitably as a maintenace P fertiliser for tea plantations in moderately P deficient soils, which need to be confirmed by field studies.

BACKGROUND: The mammalian olfactory apparatus is able to recognize and distinguish thousands of structurally diverse volatile chemicals. This chemosensory function is mediated by a very large family of seven-transmembrane olfactory (odorant) receptors encoded by approximately 1,000 genes, the majority of which are believed to be pseudogenes in humans. RESULTS: The strategy of our sequence database mining for full-length, functional candidate odorant receptor genes was based on the high overall sequence similarity and presence of a number of conserved sequence motifs in all known mammalian odorant receptors as well as the absence of introns in their coding sequences. We report here the identification and physical cloning of 347 putative human full-length odorant receptor genes. Comparative sequence analysis of the predicted gene products allowed us to identify and define a number of consensus sequence motifs and structural features of this vast family of receptors. A new nomenclature for human odorant receptors based on their chromosomal localization and phylogenetic analysis is proposed. We believe that these sequences represent the essentially complete repertoire of functional human odorant receptors. CONCLUSIONS: The identification and cloning of all functional human odorant receptor genes is an important initial step in understanding receptor-ligand specificity and combinatorial encoding of odorant stimuli in human olfaction.

Current trends in catchment management and the desire of the community for an enhanced aquatic environment require information about the water environment within the catchment. This information may be obtained from environmental monitoring programs or from the application of catchment modelling systems. Where an assessment of the effects of potential changes to the management protocol is required, the application of a catchment modelling system is necessary. An important component of the implementation of a catchment modelling system is the definition of values for the system control parameters; these control parameters are the input data to the modelling system. Historically, many of these parameters have been assumed to have an average value across the catchment which has the effect of reducing variability and, hence, inhibits simulation of catchment processes influencing the quality of stormwater runoff. When these parameters are allowed to vary spatially, the number of parameters requiring calibration becomes excessive and, in general, the available data are insufficient to enable definition of a unique set of control parameter values. New developments in information technology, however, can be used to mitigate the problems associated with definition of spatially variable control parameters for catchment modelling systems. Presented in this paper are the results of a study investigating inference of the control parameters for an urban catchment modelling system using information stored in temporal and spatial databases. It will be shown that inference of parameters using this information improves the system performance.

There is considerable interest in the wear of polyethylene and the resulting wear-debrisinduced osteolysis in artificial hip joints. Proteins play an important role as boundary lubricants in vivo in the pseudosynovial fluid, and these are reproduced in in vitro tests through the use of bovine serum. Little is known, however, about the effect of phospholipid concentrations within proteinaceous solutions on the wear of ultra-high molecular weight polyethylene (UHMWPE). The effects of protein-containing lubricants with 0.05, 0.5 and 5 per cent (w/v) phosphatidyl choline concentrations on the wear of ultra-high molecular weight polyethylene (UHMWPE) were compared with 25 per cent (v/v) bovine serum which had 0.01 per cent (w/v) lipid; the effects were compared in a hip joint simulator with smooth (n = 4) and scratched (n = 3) femoral heads. The control bovine serum lubricant produced UHWMPE wear of 55 and 115mm3/106 cycles on the smooth and rough heads respectively. The increased phospholipid concentration significantly reduced the wear rate. At the higher concentration (5% w/v phosphatidyl choline) the average wear was reduced to less than 2 mm3/106 cycles. Even with the relatively low concentrations of 0.05% w/v phosphatidyl choline the wear was reduced by at least threefold compared with the bovine serum tests for both the smooth and rough femoral heads. There may be considerable differences in the phospholipid concentrations in patients' synovial fluid and this is highly likely to produce considerable variation in wear rates. In vitro, differences in the phospholipid concentration of lubricants may also cause variation in wear rates between different simulator tests.

The purpose of this paper is to analyse the performance of our improved segmentation algorithm tested on the CEDAR benchmark database. Segmentation is achieved through the extraction of a wide range of information adjacent to or surrounding suspicious segmentation points. Initially, a heuristic technique is employed to search for structural features and to over-segment each word. For each segmentation point that is located, the left character (preceding the segmentation point), and centre character (centred on the segmentation point) are extracted along with other features from the segmentation area. The aforementioned features are presented to trained character and segmentation point validation neural networks to evaluate a number of confidence values. Finally, the confidence values are fused to obtain the final segmentation decision. Based on a detailed analysis, it was observed that the left and centre character networks increased the accuracy of the segmentation algorithm.

Contemporary Australian policy for 'stormwater quality planning', advocates best practice by adopting the principles of ecological sustainable development. The purpose of the policy is engendering community ownership and reducing stormwater contaminants at the source, reflecting the preventative paradigm. Research into the resultant plans has demonstrated that these best practice notions have not been fully realised. This is attributed to the both the policy framework and the planning rationale which demonstrate the characteristic limitations of a traditional top-down technical response to a social problem. A bottom-up citizen driven 'participative planning methodology' is offered. This methodology is an attempt to more fully realise the policy intent and address the complexities of communities' expectations and behaviours that impact water quality. The key activity is to reconceptualise the problem frame through enabling shared understandings of the causes and responses to stormwater. Copyright 2004 ASCE.

View description>>
The long-term performance of concrete slabs in alumina refineries has been found to be mostly unsatisfactory. The effect of exposure of concrete to sodium hydroxide (NaOH) of various concentrations has been reported. Failure of slabs accidentally exposed to hot caustic has been observed to be associated with cracking, crystallisation of salts in the crack and seepage of caustic into subgrade, resulting in its expansion and uplift of the slabs. This deterioration mechanisms of concrete in caustic are, however, not well understood. This paper presents findings into the interaction between a range of supplementary cementitious materials (SCM), such as blast furnace slag and silica fume, and NaOH solutions. The influence of the type of cementitious material, water-to-cementitious material ratio, concentration and temperature of NaOH on their interaction was investigated by examining the change in length of unrestrained mortar and concrete prisms exposed to NaOH solutions. The likely effect of the deterioration mechanism on the performance of restrained structural components, such as industrial slabs, is also examined by monitoring model slabs exposed to NaOH. The choice of cementitious material and its implications on the caustic resistance of concrete slabs subject to NaOH attack are presented.

The purpose of this paper is to determine the effect of mechanical loading on the transport properties of concrete. The test specimen (B I CL) used for chloride measurement, was a three-meter long reinforced beam kept in a loading state, in a confined salt fog (35 g/1 of NaCI) for fourteen years. Because of corrosion of reinforcement, the characterisation of mechanical loading was made on an other old beam (B 1 T) cast at the same time but stored in a nonaggressive environment. The measurement of tensile concrete strains using strain gauges showed two parts in the bottom of the beam: the first one is characterised by an elastic behaviour and the second one by non elastic one which is still controlled by the steel reinforcement. Total chloride profiles in relation to the depth were measured in different locations of the tensile zone of reinforced beam B I CL. Until 15 mm depth, the chloride content is constant and corresponds to the maximum chloride content available, taking into account both concrete porosity (where free chloride content corresponds to 35 g/1 of NaCI) and concrete binding capacity. Beyond 15 mm depth, total chloride profiles appear to be pure diffusion profiles allowing to calculate the effective diffusion coefficient by using a saturated model of chloride motion taking into account the non-linear binding capacity of concrete. The evolution of effective diffusion coefficient in the beam field (B I CL) is strongly correlated with the field of non elastic strains in concrete (BIT) and can increase up to 40% in the part of the beam where the non elastic damage is the more important.

Public security has become an important issue everywhere. Especially, the safe manipulation and control of various machines and vehicles has gained special attention such that the authorities keep emphasizing the strict training and censoring of human operators. Currently, such training and censoring process usually relies on the actual machines, equipment, or vehicles in the real sites. This not only has high demands in space, time and cost, but also causes another phase of public security problem. In this connection, the world-wide trend is to tackle the above dilemma by using virtual reality (VR). However, the current researches or products on VR are more matured in the software display part of VR. How to combine 3D VR display with motion platform to achieve the aforementioned training and censoring purposes is an important research issue. This paper focuses on this research issue, and the goal is to develop a multipurpose virtual-reality-based motion simulation system to meet the requirements of public security in training and censoring of human operators.

A new antenna concept, dielectric-resonator-on-patch (DROP), is presented as a way of improving the bandwidth of dielectric-resonator antennas. Driven by the objective of developing a simple low-profile antenna (height < 1 cm) for 5GHz UNII-band wireless portable computers, an example DROP antenna was designed and an excellent input return loss (> 15dB) was achieved over the entire band from 5.150 - 5.825 GHz. This design not only validates the DROP concept but also highlights its potential as a small, low-cost, lightweight antenna for mobile and wireless applications.

The comparative performance of artificial hip joints has been extensively investigated in vitro through measurements of wear volumes. in vivo a major cause of long-term failure is wear-debris-induced osteolysis. These adverse biological reactions are not simply dependent on wear volume, but are also controlled by the size and volumetric concentration of the debris. A novel model is presented which predicts functional biological activity; this is determined by integrating the product of the biological activity function and the volumetric concentration function with the wear volume over the whole particle size range. This model combines conventional wear volume measurements with particle analysis and the output from in vitro cell culture studies to provide a new indicator of osteolytic potential. The application of the model is demonstrated through comparison of the functional biological activity of wear debris from polyethylene acetabular cups articulating under three different conditions in a hip joint simulator.

© 2001 IEEE. Virtual enterprises are characterized by their dynamic nature and transient work arrangements. This in turn requires computer support systems that go beyond workflow systems to provide support for process emergence and transient team members in such enterprises. Such support systems must be based on a metamodel that is sufficiently powerful to describe virtual work arrangements and present an interface that allows users to quickly form teams, allocate responsibilities, and carry out joint work. The paper describes a metamodel, which provides a foundation for building systems to support virtual enterprises, and a prototype system that supports this model. It then describes the use of the prototype in a teaching environment.

The wet/dry cycle particular to the Northern Australian climate creates a distinctively harsh environment for the vegetation species present. At a particular location a species adapted to immersion in water may flourish whilst the site is inundated but as the water dries up will be replaced by a species capable of surviving in the drier conditions. In this way particular species continually replace one another as the cycle progresses. For this highly complex environment single date image classification does not do justice to the constantly changing patchwork of vegetation as the drying cycle progresses. As moisture is a major determinant of the dielectric properties of most non-metallic materials, and vegetation in particular, any change with time may be mapped. A multi temporal approach to the situation is well suited to highlight not only the changes in vegetation community between seasons, but also that occurring between years. A region of the South Alligator River floodplain, within Kakadu National Park was surveyed to ascertain if these changes could be accurately mapped. Analysis of three multi temporal radar images obtained by Radarsat during the period of 1998-1999 were co-registered and subjected to GMRFM segmentation. The results of this segmentation were then used in a statistical clustering algorithm in order to regroup spatially separate segments into a smaller number of classes. Subsequent air photo interpretation and ground truth information have shown that the technique is invaluable in determining the timing and location of ecological classes in a highly variable climate.

View description>>
The study of hydromechanics has identified that surface roughness has an impact on the flow characteristics of single and two-phase fluids. Technical developments in the field of two-phase flow are of great importance for improving the understanding of underground inundation and gas outbursts, in order to reduce the risks to personnel. The paper describes recent advances in the understanding of two-phase (air-water) stratified flow. A new constitutive model is presented, based upon an extension of Darcy's Law and using the concept of relative permeability. The proposed model is verified by experimental results using 'state of the art' Two Phase High Pressure Triaxial Apparatus (TPHPTA). This study presents the results of laboratory testing that will enable the development of a relationship between roughness (Joint Roughness Coefficient, JRC) and the flow rate for steady state conditions.

View description>>
Audio stream segregation is a task performed constantly by the human auditory system, yet is difficult to reproduce with a computer. The research detailed in this paper looks at performing just one method of stream segregation, the temporal coherence boundary, using a fuzzy clustering system. The main focus of the paper is to examine the effectiveness of several time-frequency distributions as the features vectors for the system. Three time-frequency distributions are examined and their effectiveness evaluated in terms of correct separation and computational complexity. The main evaluation compares the popular gamma-tone filterbank with the MPEG-7 Audio Spectrum Envelope. The results are promising indicating the less computationally expensive MPEG-7 descriptor performs well; implying stream segregation may be possible using the MPEG-7 Audio low-level description scheme.

Superior durability of fly ash concretes have been very well established by many research works throughout the world. However, the decision to use the fly ash concrete or not and also the fly ash content in the concrete is based on the cost of the concrete in most of the cases, if not all. Thus a methodology has been developed to estimate the optimum fly ash content for the lowest cost and maximum durability of the concrete. Concrete of different fly ash content were prepared and their costs were calculated. Durability properties of some of the concrete were determined by experimental measurement of their relative service life. The type of environment was also considered. Optimum fly ash content was determined based on cost, durability of the concrete, and the type of environment. The price structure of concretemaking materials in Australia was used as an example in the calculation of optimum fly ash content for the lowest price. It is expected that the price structure found in other countries would be different and accordingly the optimum fly ash content will be also different. However the methodology has been presented and this methodology can be used to calculate the optimum fly ash content for any price structure. This methodology provides scientific way of estimating the fly ash content which would give the lowest cost for an environment.

The potential use of Malaysian fly ash cement in concrete has been studied in terms of its influence on elastic properties, volume stability and durability properties. In durability studies, the resistance to chloride ingress, sulfate attack, and suppression of alkali-aggregate reactivity were examined. The results are presented and discussed. The role of the fly ash on heat of hydration, production of roller-compacted concrete, and high-strength, highperformance concrete have been proven in practice. Understanding the influence of fly ash on both fresh and hardened properties of concrete has led to its appropriate use in many important structures in Malaysia. They include the Petronas Twin Towers, the second Malaysia Singapore Causeway, and more recently considered for the construction of a major RCC dam. Properties of fly ash concrete are discussed with examples of application.

Supervised classification involves many heuristics, including the ideas of decision tree, k-nearest neighbour (k-NN), pattern frequency, neural network, and Bayesian rule, to base induction algorithms. In this paper, we propose a new instance-based induction algorithm which combines the strength of pattern frequency and distance. We define a neighbourhood of a test instance. If the neighbourhood contains training data, we use k-NN to make decisions. Otherwise, we examine the support (frequency) of certain types of subsets of the test instance, and calculate support summations for prediction. This scheme is intended to deal with outliers: when no training data is near to a test instance, then the distance measure is not a proper predictor for classification. We present an effective method to choose an "optimal" neighbourhood factor for a given data set by using a guidance from a partial training data. In this work, we find that our algorithm maintains (sometimes exceeds) the outstanding accuracy of k-NN on data sets containing pure continuous attributes, and that our algorithm greatly improves the accuracy of k-NN on data sets containing a mixture of continuous and categorical attributes. In general, our method is much superior to C5.0.

When designing a first semester 'CS1' programming subject, I advocate 'truth in sentencing'. That is, the objectives should be explicit, and the assessment tasks should reflect the objectives. This may appear to be a statement of the obvious, but few subjects satisfy these criteria. The traditional CS1 approach is to set students the task of writing extensive code, as early as possible. On closer inspection of such subjects, one finds marking schemes for exams and assignments that are generous to the point of being inconsistent with the subject objectives. Instead, students should not write any original code in CS1, and should be examined by multiple choice question.

We describe a Web based system for the delivery and marking of multiple-choice questions. While other Web systems exist that deliver such exams, those systems require either the manual mark-up of static exam questions, or generate different versions of an exam with limited variability. Such approaches result in exams that should only be administered once to a specific student. Our system is more general in how it generates different versions of an exam, using XML. © 2001 IEEE.

We describe a minimal XML mark-up for multiple choice exams. In our system, exams may be generated at anytime, by choosing a subset of questions from a pool. Furthermore, the system randomises the order of the choices within each chosen question. Thus a student may sit the exam many times. Our first version of this system has been described elsewhere. In this paper, we discuss the limitations of our first system that led to our current work, and give a description of the new system features, including XML tags for supporting collaborative authoring.

This paper presents a new single-phase power-factor-corrected (PFC) AC/DC voltage regulator using the parallel power processing scheme. By combining a PFC cell and a DC/DC cell into a new converter structure, higher conversion efficiency than those of the conventional cascaded configurations can be achieved while maintaining good power factor and fast output voltage regulation. Moreover, the storage capacitor voltage is kept reasonably low. Experimental results a given to verify the converter characteristics. This converter formation concept can also be extended to generate other useful topologies.

By adding an auxilliary winding in series with the input boost inductor of a discontinuous conduction mode (DCM) boost/flyback single-switch power-factor-corrected converter (SSPC), the storage capacitor voltage and its range of voltage fluctuation under line variations can be reduced while maintaining high power factor. Furthermore, the flyback transformer provides a direct energy transfer path to output to increase the conversion efficiency of the converter. It is also found that the power factor, the storage capacitor voltage and the conversion efficiency are controlled by the inductance ratio between the input boost inductor, the auxiliary winding and the output transformer. This paper presents a detailed analysis of the converter operating in DCM. Experimental results for a 15V/60W prototype with wide input voltage range (90-235Vrms) are given to confirm the theoretical analysis of the converter.

View description>>
This paper considers low-rate Waveform Interpolation (WI) coding. It compares the existing, common Slowly Evolving Waveform (SEW) quantisation scheme with two new schemes for representing and quantising the SEW. The first scheme uses a minimum phase estimate to reconstruct the SEW whilst the second scheme uses a pulse model whose parameters are implicitly transmitted in the quantised rapidly evolving waveform (REW). These new schemes maintain or reduce the bit rate required for transmission of the SEW. Results indicate that, for low rate WI coding, necessarily coarse SEW magnitude spectrum quantisation limits the contribution of the SEW to perceptual quality. Perceptual tests indicate that avoiding coarse spectral shape quantisation and using a fixed shape model that lends itself to smooth interpolation, maintains the perceptual quality of the synthesized speech. The proposed fixed shape model requires no bits for transmission, allowing a 12 percent reduction in the overall coder bit rate.

© Springer-Verlag Berlin Heidelberg 2001. The availability of wireless technologies such as HomeRF, WaveLAN and Bluetooth have propelled the demand for their use in the office, home and public spaces. These technologies can provide wireless multimedia services. QoS for these services can be provided by means of a MAC level QoS or a network level QoS. In this paper we describe the implementation of a network level QoS for the 802.11b technology by using the Windows 2000 Operating System. The testbed is used to obtain throughput of UDP flows created by applications such as iperf and qtcp for different number of active stations, packet sizes and packet loss. These performance evaluation results are validated by means of stochastic simulation of the testbed by using GloMoSim.

This paper describes a new audio coding scheme based on sinusoidal coding of signals. Sinusoidal coding permits the representation of a given signal through the summation of sinusoids. The parameters of the sinusoids (the amplitudes, phases and frequencies) are transmitted to allow the signal reconstruction. In the proposed scheme, the sinusoidal parameters are sorted according to energy content and perceptual significance. The most significant parameters are transmitted first allowing the use of only a small set of the parameters for signal reconstruction. The proposed scheme incurs a low delay and uses a 20 ms frame length. Results show that the coder operating at a mean rate of 39 kb/s, performs favorably in comparison with the MPEG-4 coder at 42 kb/s. © 2001 IEEE.

© Springer-Verlag Berlin Heidelberg 2001. In many pattern recognition tasks, an approach based on combining classifiers has shown a significant potential gain in comparison to the performance of an individual best classifier. This improvement turned out to be subject to a sufficient level of diversity exhibited among classifiers, which in general can be assumed as a selective property of classifier subsets. Given a large number of classifiers, an intelligent classifier selection process becomes a crucial issue of multiple classifier system design. In this paper, we have investigated three evolutionary optimization methods for the classifier selection task. Based on our previous studies of various diversity measures and their correlation with majority voting error we have adopted majority voting performance computed for the validation set directly as a fitness function guiding the search. To prevent from training data overfitting we extracted a population of best unique classifier combinations, and used them for second stage majority voting. In this work we intend to show empirically, that using efficient evolutionary-based selection leads to the results comparable to absolutely best, found exhaustively. Moreover, as we showed for selected datasets, introducing a second stage combining by majority voting has the potential for both, further improvement of the recognition rate and increase of the reliability of combined outputs.

© 2001 ARCME, Univ of WA. Excessive post-operative bleeding occurs in approximately one out of eight patients who undergo heart bypass surgery. Earlier workers have identified laboratory parameters that are correlated with post-operative blood loss but these correlations are not strong enough to be clinically useful. This paper describes a predictor that combines several of these parameters using Naive Bayesian Reasoning, to produce a clinically useful predictor of blood loss.

Careful examination of packet traces taken front the MBone reveals a significant number of multiple successive packet losses, even though losses are predominantly isolated. This paper presents a method for reducing the number of burst losses by transforming them into single isolated losses. In this method, the first step is to separate critical video information from non-critical video signals, assuming the availability of an efficient layered coder. Secondly, by exploiting the unordered delivery feature of UDP, packets are interleaved and randomized so as to spread out the loss of critical video information. Finally, in order to reduce the number of random losses, redundant packets of essential video data are included in the interleaved/randomized packet sequence. To prove the effectiveness of this method, experiments were conducted on packet traces collected front the MBone. Results indicate that interleaving/randomization alone, significantly reduces consecutive packet burst losses. Furthermore, results are even better with the inclusion of essential redundant video data, which dramatically reduces the number of disjoint losses.

In the field of wastewater treatment, energy-intensive and highly mechanized technologies are giving way to nature-based technologies that utilize solar energy and living organisms. Constructed treatment wetland (CTW) technology has played an important role in bringing about the change. Wetland technology can provide cheap and effective wastewater treatment in both temperate and tropical climates, and are suitable for adoption in both industrialized as well as developing nations. Currently, CTWs are being utilized for removal of a range of pollutants and a broad variety of wastewaters worldwide. The objective of this article is to provide a comprehensive review of the CTW technology and to present the pollutant removal performance experiences gathered through the application of this technology around the world.

This paper presents a methodology for extracting road edge and lane information for smart and intelligent navigation of vehicles. The range information provided by a fast laser range-measuring device is processed by an extended Kalman filter to extract the road edge or curb information. The resultant road edge information is used to aid in the extraction of the lane boundary from a CCD camera image. Hough Transform (HT) is used to extract the candidate lane boundary edges, and the most probable lane boundary is determined using an Active Line Model based on minimizing an appropriate Energy function. Experimental results are presented to demonstrate the effectiveness of the combined Laser and Vision strategy for road-edge and lane boundary detection.

This paper reports the results of experimental modal analysis of a five-storey benchmark model with impact excitation using HP-VXI data acquisition system and LMS CADA-X software. A numerical was also conducted. The benchmark building model was identified both in terms of its dynamic parameters, namely, natural frequencies, mode shapes and damping ratios as well as its structural properties, namely, the mass, stiffness and damping matrices. The results showed a good agreement between the analytical and experimental results. These parameters enabled further analysis and modeling of the building frame in the presence of various control devices using different control algorithms, aimed at reducing earthquake-induced building vibrations.

© 2001 IEEE. Image edge detection in computer vision and image processing is a process which detects one kind of significant feature in an image that appears as large delta values in intensities. In this paper, a parallel algorithmic skeleton for edge detection is proposed based on the Spiral Architecture and the Gaussian multi-scale theory. UNIX-based network programming mechanisms in C are used for the implementation on a cluster of Sun-workstations. Our work provides an efficient algorithm for edge detection and is robust to noise.

The objective of the work described in this paper is the examination of the design and control opportunities presented by systems with large numbers of small, two-state actuators acting in parallel. An array of two-state actuators, i.e. a bundle of binary actuators, can be regarded as a simplified model of biological muscle. In recent years, the development of MEMS (Micro-Electromechanical Systems) has shown a great potential for building mechanical elements in a very small scale. However, there are sortie other issues for integrating a parallel array system that cannot be solved by advances of material research alone. From the mechanical designer's point of view, large numbers of active elements have to be deployed at appropriate locations in the system. For control purposes, if a binary system is intended, the mathematical model can be very different from that of hyper-redundant manipulators. In addition to theoretical development, two experiments, one for investigating static problems and one for inve stigating dynamic problems, will also be described in the paper.

© 2001 IEEE. Security and safety are important factors that baffle the development and practicality of active networks. However, most research on active networks focuses on security. Based on the analysis of safety requirements of active networks and possibility of using the safety kernel that is a new concept of safety assurance, this paper presents a safety assurance mechanism SKAN for active networks. We design it from several important aspects of safety policy, practice of SKAN, reuse and effect. SKAN can address common problems found in active networks, such as lack of the effective support of application variety and expressiveness of safety policy, etc.

A time domain method is presented to identify the moving loads on the bridge deck from measuring strains. The bridge deck is modelled as a rectangular orthotropic plate. The vehicle is modelled as two axle loads moving on the bridge deck. Like all inverse problems, the identification is an ill-posed problem, so a regularization technique is employed to stabilize the solution. This paper gives a demonstration on the robustness of the solution technique to the effects of measurement noise and in the identification of eccentric moving loads. Numerical examples show that the method is effective and practical for moving load identification.
