A generic architecture incorporating agent based and data warehousing technologies for the design of decision support systems (DSS) is presented. The architecture consists of an interface agent, control and service agents, and a warehouse agent organized in a hierarchical structure which supports cooperative problem solving. The architecture has been designed to support DSS type query processing and to provide a framework for integrating both intelligent and conventional heterogeneous software components. A data warehouse is specifically used to support efficient DSS type query processing and at the same time facilitate the integration of distributed databases. The architecture provides a platform for cooperative problem solving in a complex environment. Implementation issues relating to such an architecture are also addressed.

Several methods of measuring plant-available cadmium (Cd) were compared using soils that had accumulated Cd under normal New Zealand agricultural practices (low total Cd concentrations, and phosphatic fertiliser as the dominant Cd source). The study encompassed 9 New Zealand soils with different Cd input histories. Cadmium was extracted from these soils by demineralised water, 0.05 M Na2EDTA, l M NH4OAC (pH 7), 0.01 M CaCl2, and 0.05 M CaCl2 and quantified by differential pulse anodic stripping voltammetry (DP-ASV) and graphite furnace atomic absorption spectrophotometry (AAS). The DP-ASV measures the free Cd ion and that associated with labile complexes, but not large organic Cd complexes. Extractable Cd levels were compared with those which are plant-available, as determined by pot studies (lettuce). The 0.01 M CaCl2-extractable Cd measured by AAS and 0.05 M CaCl2-extractable Cd measured by DP-ASV gave the best estimate of plant availability of Cd.

This paper describes a rectified synthesis method where a rigid body of a six-bar linkage with well-defined transmission angles is guided to pass through four precision positions. The procedure includes the elimination of circuit, branch, and order defects. This is achieved by decomposing the six-bar mechanism into groups of vector pairs called dyads and groups of three vectors called triads. The algebraic method of synthesis can be applied to rectify those chains. Although these defects can be eliminated, it has been a challenging task in the past. The procedure has been implemented for a Watt I crank-driven six-bar linkage in the interactive synthesis package RECSYN.

A solution for the mutual admittance between modes in identical circular apertures is extended to the general case of coupling between different-sized apertures. Two alternative representations for the mode coupling integrals are derived. One is a gamma-function series representation with a limited range of application. The other is an improved integral formulation which is better suited to numerical calculation than the original integrals and was obtained by means,of an integral transform in the complex plane. The accuracy of this improved integral formulation is demonstrated by comparing computed results with measured data for a three-element test array. Excellent agreement is obtained between theory and experiment for both coupling coefficients and radiation patterns. Results are also presented for an eight-horn feed cluster for a reflector. © IEE, 1996.

View description>>
The Beckwith-Wiedemann syndrome (BWS) is genetically linked to chromosome 11p15.5, and a variety of observations suggest that deregulation of imprinted genes in this region is causally involved in the pathogenesis of the disease. It has been shown that in some patients without cytogenetic abnormalities the otherwise repressed maternal copy of the insulin-like growth factor 2 (IGF2) gene is expressed, leading to biallelic expression of IGF2. In some of these cases, this is accompanied by repression and DNA methylation of the maternal (otherwise active) copy of the neighbouring H19 gene. Hence, it is attractive to think that mutations may interfere with some aspect of H19 imprinting, thus leading to an inactive maternal allele, and indirectly to activation of the maternal IGF2 allele as reported in mice with an H19 gene deletion. However, no mutations have been identified so far in these patients. The only known mutations associated with BWS are maternally transmitted translocations, which are clustered in two locations centromeric to IGF2. The first cluster is 200-400 kb from IGF2 and the second is several megabases away. Hence, genes located far from the translocation breakpoints are potentially deregulated by them. Here we provide the first evidence of alteration of imprinting in a translocation family, with biallelic expression of IGF2 and altered DNA replication patterns in the IGF2 region. Interestingly, H19 imprinting was normal, suggesting an H19-independent pathway to biallelic IGF2 transcription, DNA methylation in IGF2 remained monoallelic, suggesting that the mutation in this family had uncoupled allele-specific methylation from expression.

View description>>
This paper describes a pitch detection algorithm which builds on the `Composite Autocorrelation' method. By explicitly considering `prototype' waveforms within the constituent autocorrelation computations, and detecting the pitch at frequent (5 ms) intervals, the algorithm produces a robust and continuous pitch track. This leads to a reduced-delay algorithm that overcomes many of the difficulties encountered when using autocorrelation-based techniques in Prototype Waveform (PW) / Waveform Interpolation (WI) coders. In particular, the technique is able to rapidly track the onsets of voiced and unvoiced speech sections. The algorithm is also able to maintain track for both high and low pitch speakers with promising results at this reduced delay.

In the sheet metal industry, high levels of impact noise are associated with the frequent occurrence of noise induced hearing loss in workers. A literature review is presented of research on impact noise from punch and power presses in this industry. The review shows that considerable work has been done, and that much is understood about, the noise generation mechanisms in these machines. While more fundamental research will undoubtedly produce greater insight, there is a need for much more design and development work to produce quieter machines and processes for the sheet metal industry.

The paper recounts the investigation of a dairy sire prediction capability based on Cascade Correlation neural networks to study influences relating the performance of offspring to their parents. The context of the problem is the artificial insemination breeding program for the Australian dairy industry. The networks are used to screen observed information in the database to relate it to best combinations of dam and sire. The voluminous data is quite noisy and is subject to genetic and environmental influences. The intention is to extract linear and nonlinear relationships from among the input variables without specifying their form. A number of scenarios are employed which recast the data into different forms. In particular, it was discovered that the problem could be restructured and the data supplemented with transformed data to produce succinct input patterns of manageable dimensionality, which allowed for a substantially improved predictive capability. It was then found that reasonable daughter predictions could be obtained of about 10%, as measured by her milk production. Results are compared with those obtained using two alternate neural network methods. Crude statistical methods are employed to evaluate the performance of the neural networks.

An algorithm for the detection of the Fundamental Pitch Period (F 0) at low delay, utilizing Dynamic Programming (DP) Techniques and those of the Viterbi Algorithm (VA) is presented. The algorithm results in a low delay, accurate pitch detector which is vital for low rate speech coders, such as those utilizing Prototype Waveform Interpolation (PWI) techniques. Current methods, based on autocorrelation incur a significant look-ahead delay and are therefore considered unsuitable for use in such speech coders. The algorithm described uses improved, non-linear Pitch Detection, with a substantial extension of a Viterbi-type tracking algorithm to maintain a smooth pitch track.

A three year field trial assessing the suitability of mine waste rock as a surrogate subsoil with different depths of topsoil showed that pasture yield was significantly lower in the unmodified waste rock (UWR) treatments compared to waste rock modified with lime and potassic superphosphate (MWR) during the first two years but there was no difference in yield in the third year between the waste rock treatments. The reduced yield in UWR during the first two years was considered to be due to phytotoxic levels of aluminium (Al) in the UWR soil solution. Soil samples from the waste rock interface (A) and waste rock at depth ≤ 300 mm (B) collected at the end of the three year trial were analysed for different forms of soil Al, total soluble fluoride (F), dissolved organic carbon (DOC) and soil pH to determine whether organic matter and F leachate from the topsoil reduced Al toxicity at the waste rock interface (A) during soil development over 3 years. Results showed that after 3 years, 0.02 M CaCl2 extractable Al (Al(Ca)) and 1 M KCl extractable exchangeable + soluble Al (Al(K)) were effectively reduced in the MWR interface (A) by lime and fertiliser applications but they remained at very high phytotoxic levels (Al(Ca) = 17-21 μg g-1, Al(K)=261-339 μg g-1) in the UWR interface (A) irrespective of topsoil depth treatment. The corresponding organic bound Al (Al(OM)) ranged from 200 to 214 μg g-1 and DOC was in the range 169-203 μg g-1 in both UWR and MWR interfaces (A). These values were a significant two-fold higher than the values at depth ≤300 mm (B) which were considered to be the original levels of Al(OM) and DOC in UWR. The increase in Al(OM) and DOC by the third year is probably due to progressive leaching of organic ligands produced from the decomposition of organic matter in the topsoil subject to an annual rainfall of 2500 mm. This evidence for the reduction in Al toxicity by organic matter is further supported by significant dry root density (DRD) in the UWR ...

This paper proposes a new nonlinear signal processing by using a three‐layered network which is trained with self‐organized clustering and supervised learning. The network consists of three layers, i.e., a self‐organized layer, an evaluation layer, and an output layer. Since the evaluation layer is designed as a simple perceptron network and the output layer is designed as the fixed weight linear nodes, the training complexity is the same as the self‐organized clustering and a simple perceptron network. In other words, quite high speed training can be realized. Generally speaking, since the data range usually used in signal processing is arbitrarily large, the network output should also cover this range. However, it may be difficult for only one node in the network to output these data. Instead of this technique, if this dynamic range is covered by using several nodes, the complexity of each node is reduced and the associated range is also quite limited. This results in a higher performance of this network than the conventional ones. As one of the objectives, this paper introduces the spectrum envelope estimation of speech waveforms. It is shown that accurate spectrum envelopes can be obtained. © 1996, Acoustical Society of America. All rights reserved.

View description>>
In Australia, colluvial soils form large terrains which are often subjected to considerable erosion and mass movement. This study presents a laboratory evaluation of the improvement effected by hydrated lime, milled blast furnace slag and fly ash on a fine grained (erosive) colluvial soil in New South Wales, Australia. Geotechnical tests were conducted to determine the compaction and consolidation characteristics and the compressive and shear strength properties of the blended and natural soil specimens. The effect of these additives on the Atterberg limits and pH levels is also investigated. As large amounts of fly ash and steel slag are produced in New South Wales, it is economically attractive to utilize these industrial by-products for ground improvement rather than employing conventional methods such as lime treatment. This study demonstrates that for the colluvial soil tested, milled slag is the most effective in terms of improving the internal friction angle of the treated soil, while lime is the most suitable for achieving the optimum compressive strength. Non-pozzolanic fly ash is found to be inappropriate as a soil improving agent. The cost of ground treatment using the various additives is also estimated and compared. © 1996 Chapman & Hall.

In Australia the utilisation of clay in the construction of landfill liners has recently come under criticism either due to the difficulty in reproducing the laboratory results on site, or because of the potential for cracking of the compacted liner after construction. Realising that clay is weak in tension and given the possibility of certain areas of the liner being subjected to flexure, a testing program was undertaken to determine the effects of placement (compaction), moisture content and internal reinforcement on the potential failure of clay liners. In particular, this paper discusses the load carrying capacity and deformation sustained by compacted clay beams in flexure, and the improvement gained through the introduction of an economical reinforcement in the form of galvanised steel wire netting. Results obtained by flexural bending tests are discussed in detail, and the extent of improvement provided by galvanised wire netting is evaluated. © 1997 Elsevier Science Ltd. All rights reserved.

In many parts of the world, residual soils are used for the construction of impervious dam cores. This paper discusses the experimental details and design aspects of sand filters in the retention of a range of particle sizes in a clay slurry. Lateritic residual soil has a propensity to crack at relatively small tensile strains, if compacted either at low moisture content or at energy levels greater than the standard Proctor method. From laboratory results, a distinct demarcation between effective and noneffective filters was identified in considering the filter permeability and a specific particle size of the base soil (clay floes) retained by the filter. The equivalent of specific grain size <5g5, determined by hydrometer analysis was considered as the reference base particle, and the cation concentration of the base soil slurry was taken to represent the typical reservoir water chemistry of several dams in Thailand. The permeability of the filter was examined as a function of the sand grain sizes and the resulting empirical relationships are given in the paper. The performance of granular filters, including clogging behaviour, has'been studied according to~the particle sizes and uniformity coefficients of the filter media. The applicability of the proposed empirical relationships in practice is discussed in contrast to the conventional filter criteria.

Multimedia conferencing services have specific performance requirements with respect to the exchange of continuous media. One of these requirements is the synchronization within and between related streams. This article identifies synchronization requirements and solutions relevant for conferencing services that operate in an open distributed environment as defined in TINA-C. Based on the TINA service lifecycle, synchronization requirements and policies are described from different stakeholder perspectives. Synchronization is then specified in detail using the TINA information, computational and engineering languages. Finally, a description of the implementation of synchronization for a multimedia conferencing service is provided using a DPE platform. The synchronization object is proposed as an additional component available for the DPE that needs to deal with real-time audio-visual streams.

A Self-Organizing Neural Fuzzy Inference Network (SONFIN) with on-line learning ability is proposed in this paper. The SONFIN in inherently a fuzzy rule-based model possessing neural network's learning ability. In contrast to the general adaptive neural fuzzy networks, where the rules should be decided in advance before parameter learning is performed, there are no rules initially in the SONFIN. They are created and adapted as on-line learning proceeds via simultaneous structure and parameter identification. In this structure identification of the precondition part, the input space is partitioned in a flexible way according to an aligned clustering-based algorithm. As to the structure identification of the consequent part, only a singleton value selected by a clustering method is assigned to each rule initially. Afterwards, some additional terms (a linear combination of input variables) are added to the consequent part when necessary. Furthermore, to enhance the knowledge representation ability of the SONFIN, a linear transformation for each input variable can be incorporated into the network so that much fewer rules are needed or higher accuracy can be achieved. Proper linear transformation are also learned dynamically in the parameter identification phase of the SONFIN. To demonstrate the capability of the proposed SONFIN, simulations in identification and control problems are done. Effectiveness of the SONFIN is verified from these simulations.

View description>>
Brachial artery pressure waveforms were recorded with manometer-tipped catheters in seven mildly hypertensive subjects, aged 20-70 years. Reflections generated by an external occlusion of the brachial artery immediately distal to the entry site produced an oscillatory component in the pressure signal, nearly 30% of the normal pulse amplitude. The reflected waves exhibited a broad resonant behaviour akin to a damped organ pipe. The usual absence or small amplitude of similar oscillatory components implies that no significant reflections normally occur in the brachial artery. The normal, virtual absence of reflections requires an alternative explanation for the increasing pulse pressure towards the periphery. This can be found in a rising arterial characteristic impedance caused by the reduced compliance of smaller arteries.

Excessive phosphorus (P as orthophosphate) is one of the major pollutants in natural water that are responsible for algal blooms and eutrophication. P removal by slag is an attractive solution if the P sorption capacity of slag is significant. To design an efficient land treatment facility, basic information on the behaviour of P in the media-water environment is required. In this study, detailed column experiments were conducted to study the P transport under dynamic condition, and mathematical models were developed to describe this process. The column experiments conducted with dust and cake waste products (slag) from a steel industry as adsorbing media indicated that they had higher sorption capacity of P than that of a sandy loam soil from North Sydney, Australia. P transport in the dust and cake columns exhibited characteristic S-shaped or curvilinear breakthrough curves. The simulated results from a dynamic physical non-equilibrium sorption model (DPNSM) and Freundlich isotherm constants satisfactorily matched the corresponding experimental breakthrough data. The mobility of P is restricted by the adsorbents and it is proportional to the sorption capacity of them.

This paper proposes a four-layered fuzzy language acquisition network (FLAN) for acquiring fuzzy language. It can catch the intended information from a sentence (command) spoken in natural language with fuzzy terms. The intended information includes a meaningful semantic action and the fuzzy linguistic information of that action (for example, the phrase “move forward” represents the meaningful semantic action and the phrase “very high speed” represents the linguistic information in the fuzzy command “Move forward in a very high speed.”). The proposed FLAN has two important features. First, we can make no restrictions whatever on the fuzzy language input which is used to specify the desired information, and the network requires no acoustic, prosodic, grammar and syntactic structure. Second, the linguistic information of an action is learned automatically and it is represented by fuzzy numbers based on α-level sets. A supervised learning scheme is proposed to train the FLAN on fuzzy training data. This learning scheme consists of the mutual-information (MI) supervised learning algorithm for learning meaningful semantic actions, and the fuzzy backpropagation (FBP) learning algorithm for learning linguistic information. An experimental system is constructed to illustrate the performance and applicability of the proposed FLAN.

In this paper, techniques are presented to extend FDTD, PML and Mur's second order ABC to the non-uniform mesh case for scattering problems from a consideration of improving the efficiency of computer codes to run on parallel computers. An alternative method to obtain the space derivatives in non-uniform mesh FDTD and non-uniform mesh PML ABC is presented which provides a second order accuracy. Mur's second order ABC has also been extended to the non-uniform mesh case with a First order accuracy which is an improvement over an existing method. A method of extending the pure scattered-field formulation to the PML medium is described. The electric fields inside a single layer dielectric sphere as well as a three layer dielectric sphere illuminated by a sinusoidal uniform plane wave have been computed which compare well with the results from an exact formulation. © 1996 Taylor & Francis.

Cadmium (Cd), a potentially toxic heavy metal for humans and animals, accumulates in the liver and kidneys of older animals grazing New Zealand and Australian pastoral soils. Phosphorus (P) fertiliser is the major input of Cd into these farming systems. A study was conducted to evaluate the effects, over 10 years, of annual application (30 kg P ha-1 yr-1) of four forms of P fertilisers having different solubilities and Cd contents [41, 32, 10 and 5 μg Cd g-1 for North Carolina phosphate rock (NCPR), single superphosphate (SSP), diammonium phosphate (DAP) made from low Cd phosphate rocks and Jordan phosphate rock (JPR) respectively] on soil and herbage Cd concentrations. Ten years of fertiliser application caused a marked increase in surface soil Cd concentrations. Total soil Cd was significantly higher in SSP and NCPR treatments compared to control (no P fertiliser), JPR and DAP treatments in the 0-30 and 30-75 mm soil depths. Plant-available Cd (0.01 M CaCl2 extractable Cd) was higher in SSP treatments than in control and other fertiliser treatments. Chemical analysis of herbage samples showed that there was no significant difference in Cd concentration in pasture grasses between treatments in the second year of the trial but in the eighth and tenth year, plots fertilised with SSP and NCPR had significantly higher Cd in pasture grasses in most of the seasonal cuts compared to control, JPR and DAP. Cadmium recovery by both grasses and clover was less than 5% of Cd applied in fertiliser. Clover Cd concentration and yield were much lower than those for grass and therefore its contribution to pasture Cd uptake was very low (< 7%). A strong seasonal effect on grass Cd concentration, which is inversely related to pasture growth rate, was observed in all three sampling years - Cd concentration was highest during autumn and lowest in spring. Total Cd contents of the fertilisers and their rate of dissolution rather than soil pH [pH (H2O) at 30-75 mm depth of 5.39, 5.20, ...

This study describes some of the effects of 8 years of annual application of 6 types of phosphatic fertilisers on the chemical composition and aluminium (Al) speciation in soil solution extracted from a soil under pasture. Soil samples at 2 depths, 0-30 and 30-75 mm, were collected at the end of 8 years. Soil solutions were extracted by centrifuging at 12 000 RCF and analysed for Al, Na, K, Ca, Mg, F, NO3, Cl, and SO4, as well as pH and ionic strength. Soil and soil solution pH were significantly increased at both depths by application of North Carolina phosphate rock (NCPR) compared with the control. In contrast, diammonium phosphate (DAP) significantly decreased the soil and solution pH. Single superphosphate (SSP) did not have any significant effect on soil or solution pH compared with the untreated control. The surface soil (0-30 mm) solution pH was on average 0.6 of a unit higher than the subsurface soil (30-75 mm) solution pH. Total monomeric Al concentration [Al], measured by the pyrocatecol violet (PCV; 4 min) method, ranged from 1.5 to 4.8 μM in the surface soil and 2.5 to 12.2 μM in the subsurface soil. The DAP and higher rates of SSP application resulted in a large increase in total and inorganic monomeric [Al] in the soil solution extracted from the subsurface soil. Total soluble [F] ranged from 2.7 to 23.5 μM and 3.2 to 25.6 μM in the surface and subsurface soils, respectively, and was significantly increased by the application of NCPR and by higher rates of SSP. The predominant forms of inorganic monomeric Al present in the soil solution were estimated to be the non-phytotoxic Al-F complexes, AIF2+, and AIF2/+. There was a marked decrease in toxic Al species (Al3+, Al(OH)2+, Al(OH)2/+) in soil solution following NCPR and SSP application. This was due primarily to complexation of Al with F derived from these fertilisers forming non-toxic Al-F complexes. The results suggest that the long-term application of reactive phosphate rock such as NCPR may con...

In this study, the applicability and the advantages of the downflow floating medium filter (DFF) in wastewater treatment were examined. The experimental results indicated that the DFF with in-line flocculation addition is a good pretreatment unit to reduce phosphorus load (up to 80-89% removal). The DFF also resulted in uniform filterable-flocs of 32-42 µm throughout the filter run. Thus it can also successfully be used as a flocculator. The backwashing of floating medium was achieved with a small quantity of water and at low backwash velocity. The introduction of floating medium filter bed on top of a coarse sand filter unit (CSF) increased the filter run time and removal efficiency (more than 87 and 94% of NH3-N and T-P removal respectively), particularly at a low filtration rate (5 m3/m2.h).

This paper examines the performance of a direct sequence, spread spectrum (DSSS) multiple access (MA) system used over two typical, frequency-selective, fading satellite channels. In an attempt to increase the system efficiency, an adaptive receiver described by Rapajic and Vucetic [1] has been implemented. This system has been combined with soft-decision convolutional coding in order to improve the system performance under the fading conditions relative to the uncoded system and to allow as many simultaneous users as possible. Various code rates have been examined and the results are given. This paper specifically focuses on DSSS-MA systems with low spreading ratios. The satellite channels used in this paper were produced by models developed as a result of experimental measurements of fading satellite channels for rural and urban environments.

View description>>
Framed off-shore structures are normally made of tubular members. These members are prone to damage by collision from supply boats or by the impact of dropped objects. Experimental and theoretical work has indicated that such damage can cause a significant loss of member strength and the grouting is an effective way of repair for tubular members with a moderate degree of damage. An existing numerical approach based on the method of orthogonalised load/deflection states has been successfully employed to establish the pre- and post-ultimate force/displacement relationships of damaged tubes and grout-filled damaged tubes. The paper comprises an explanation of the analytical method used, adaptation of the method for analysis of fully grout-filled damaged tubes and the presentation of the results. A comparison is made between the experimental and analytical results.

An adaptive enhancement algorithm of signal disturbed by the impulse noise and the white Gaussian noise is proposed in this paper. If the strong dependence between signal enhancement and needed-parameter estimation exists in an algorithm, it is difficult to reduce a large bias occurring in the first estimation. To weaken their relationship, it is considered to introduce a total least squares (TLS) algorithm which estimates model parameters directly from disturbed signals. However, the TLS estimation accuracy is dramatically deteriorated by the impulse noise, even if the TLS estimation accuracy is held to the non-Gaussian noise in some degree. Hence, we ensure the robustness of the algorithm by replacing a high amplitude signal with an estimated value based on a likelihood ratio test. Using these signals, we develop an algorithm based on the TLS and the EM algorithm for enhancing the disturbed signal. We also show the effectiveness of the proposed algorithm through computer simulations.

View description>>
The relative effectiveness of resource management regimes is widely discussed. Sustainability and ecosystem health are two dimensions upon which the effect of management is judged. Evaluating resource management requires long time spans. We look at the impact of management on fish and forest resources by taking a life cycle approach to the exploitation of natural capital. Russian ethnographer Gumilev (1990) describes the process of how human systems go through a set of phases that parallel the birth, growth, maturity, and death stages of the life cycle. The process of adaptive renewal proposed by Holling (1992), too, has life cycle characteristics. The primary variables used to represent the phases of the renewal cycle are the amount of capital that is accumulated and the connectedness in the system. We apply the renewal cycle to a fishery and forestry example in the U.S. Pacific Northwest to see how management regimes alter the capital stock of these systems. In these two examples, 90% of the natural capital is lost or projected to be lost over a century and a half of exploitation. The management regime in both cases evolves toward greater inflexibility. Based on these two examples, resource management does not seem to lead to sustainability or ecosystem health. © 1996 Blackwell Science, Inc.

Mechanisms interacting with their environments that possess complete contact force controllability such as multifingered hands and walking vehicles are considered in this article. In these systems, the redundancy in actuation can be used to optimize the force distribution characteristics. The resulting optimization problems can be highly nonlinear. Here, the redundancy in actuation is characterized using geometric reasoning which leads to simplifications in the formulation of the optimization problems. Next, advanced polynomial continuation techniques are adapted to solve for the global optimum of an important nonlinear optimization problem for the case of four frictional contacts. The algorithms developed here are not suited for real-time implementation. However, these algorithms can be used in off-line force planning, and they can be used to develop look-up tables for certain applications. The outputs of these algorithms can also be used as a baseline to evaluate the effectiveness of sub-optimal schemes.

Several extragalactic HI surveys using a λ21 cm 13-beam focal plane array will begin in early 1997 using the Parkes 64 m telescope. These surveys are designed to detect efficiently nearby galaxies that have failed to be identified optically because of low optical surface brightness or high optical extinction. We discuss scientific and technical aspects of the multibeam receiver, including astronomical objectives, feed, receiver and correlator design and data acquisition. A comparison with other telescopes shows that the Parkes multibeam receiver has significant speed advantages for any large-area λ21 cm galaxy survey in the velocity range range 0–14000 km s−1.

To achieve a user data rate of 20 Mbit/s in the high performance local area network (HIPERLAN) system operating in indoor environments, channel equalization must be used to mitigate the effects of multipath propagation. If, however, the indoor channel impulse response length is too long, then the multipath power outside of the equalisation capability of the equalizer acts as a form of self interference. Moreover, co-channel interference may also be present at the detector input. Considering these two effects as well as the rms delay spread, this paper derives analytical expressions for the probability of outage. © 1996 Kluwer Academic Publishers.

In order to accomplish practical deployment modelling for system performance evaluation and comparison for possible modulation and equalisation schemes to be used in HIPERLAN, a wide band tapped delay line (WTDL) channel model has been adopted by ETSI to characterise the multipath fading in the indoor radio environment. Based on this statistical channel model, and using Monte Carlo method, this paper evaluates the average probability of error for linear and decision feedback equalisers as a function of signal-to-noise ratio. It also evaluates the matched filter bound for this channel model. The results show the optimum performance levels achievable via the use of any equaliser. © 1996 Kluwer Academic Publishers.

Despite considerable advancement in anticancer therapy, minimal residual disease (MRD) is still a major problem in the clinical management of cancer, including lymphoma. In this report, we have studied the antitumor effects of interleukin-12 (IL-12) against an aggressive liver metastatic murine RAW117-H10 lymphoma. Our results using three different doses of IL-12 (0.175, 0.35 and 0.7 micrograms/mouse) showed that a 0.35 micrograms dose is the most efficacious against lymphoma grown in intact mice. Furthermore, we have evaluated the therapeutic effects of IL-12 against residual lymphoma in a transplantation setting. BALB/c mice were treated with high-dose therapy (HDT) and transplanted with syngeneic bone marrow cells added with a known number of RAW117-H10 lymphoma cells to mimic the clinical situation of MRD. The mice were then treated with IL-12 (0.25 micrograms/mouse/day) alone or IL-12 plus activated cytotoxic effector cells. Our results showed that IL-12 had a significant (P < 0.05) antitumor therapeutic effect against liver metastatic lymphoma grown in intact mice as well as in lymphoma-bearing mice treated with HDT followed by stem cell transplantation as determined by survival period. The therapeutic effect of IL-12 was also demonstrated by a very significant decrease (P < 0.05) in the tumor burden in livers from the IL-12-treated mice. Mice that were treated with IL-12 following HDT and hematopoietic stem cell transplantation had a significant decrease in circulating white blood cells (P < 0.05), a significant increase in spleen weight and cellularity (P < 0.05), and hematopoietic progenitor cells (P < 0.05), a significant increase in the number of splenocytes expressing IL-2 alpha-chain receptor (P < 0.05), and an increase in the frequency of natural killer cells in their spleens. These studies suggest that cytokines such as IL-12 may have the potential to mediate antitumor effects against residual lymphoma without compromising lymphohematopoietic recov...

This study was aimed at investigating the effect of particle size, mostly in the submicron range, on break-through stage of filtration. Latex beads, with diameters ranging from 0.46- to 2.967-μm were filtered through filter grains of diameters 0.1-, 0.175- and 0.45-mm. Experimental conditions were chosen so as to obtain breakthrough curves. The experimental results showed that the initial efficiency follows the pattern reported by previous experimental and theoretical studies, i.e., lower efficiency for 0.825-μm particles which fall in the range of critical size. However, the particle removal during the transient stage increased with an increase in particle size for the range of sizes studied. This pattern is qualitatively confirmed by the theoretical predictions of Vigneswaran and Chang (1986) model. This study also provides experimental verification of the effect of the ratio of particle size and grain size at different stages of filtration.

It is demonstrated in this paper that relatively simple linkages can give rise to problems that cannot be addressed by dyadic decomposition methods, and that solution of these problems can be far more complex.

The effect of noise enhancement of the linear decorrelating detector (LDD) is investigated by studying a low complexity receiver for synchronous Code Division Multiple Access (CDMA) systems. Using Gold codes as the spreading sequences a general formula of the decorrelating matrix is obtained, which leads to a simplified receiver structure and explicit expression of the bit error ratio (BER). It is shown that even with multiple access interference (MAI) reduced, the BER of the system is still dependent on the bandwidth efficiency. For a given bandwidth, efficiency, the system performance improves when the processing gain is increased.

In this paper a near-far resistance detector for asynchronous Code-Division Multiple-Access (CDMA) systems operating in Additive White Gaussian Noise (AWGN) channels is presented. The multi-user interference caused by K users transmitting simultaneously, each with a specific signature sequence, is completely removed at the receiver. The complexity of this detector grows only linearly with the number of users, as compared to the optimum multi-user detector which requires exponential complexity in the number of users. A modified algorithm based on time diversity is described. It performs detection on a bit-by-bit basis and overcomes the complexity of using a sequence detector. The performance of this detector is shown to be superior to that of the conventional receiver.

This paper presents some results from a major research project carried out on corrosion of steel reinforcement in concrete. The performance of a range of Portland and blended cement concretes containing fly ash and blast furnace slag exposed to simulated marine conditions was evaluated over a period of six years. A large amount of data relating to corrosion of embedded steel in concrete was obtained in this project. Long-term half cell potential data on reinforcement within concrete slabs and resistivity data on the same concrete specimens has been considered in detail in this paper. Rates of corrosion of steel in concrete were also measured using potentiodynarnic anodic polarization procedures. Trends observed in the data were different for the portland and blended cement concretes investigated. It was found that concrete resistivity may influence the measured half cell potential of steel in concrete. This factor needs to be taken into account for half cell potential data interpretations.

The paper discusses the variety of means deployed in order to provide a flexible, self-directed learning environment for the course. This led to: The inclusion of QUIKF'ro!, a specially developed Computer Based Training package on Internet services and resources; providing easy access to learning materials from campus or from home; and using innovative assessment methods which aim at improving the process and quality of assessment. Assessment was carried out online and used anonymous assessment, peer assessment and criterion-referenced marking.

Telecommunications networks are exposed to a plethora of accents and languages. Fundamental to current and future systems are low rate speech coders. This paper examines the problems associated with speech coding of different languages and accents. Our investigations show that most low-rate (8 kb/s and below) speech coders show bias towards non-accented English. When the coders are used for heavily accented English or other languages, significant performance degradation is noted. This paper examines the reasons for such variations and some approaches for improving coder performance.

Recent, research in circularly polarized dielectric resonator antennas (DRAs) has shown that a wide axial ratio bandwidth can be achieved from a single point fed DRA. It is the purpose of this paper to investigate the performance of the dielectric cross within a cavity structure. The optimization of the geometry and the effects on overall operation are discussed.

A new kind of nonlinear adaptive filter, the adaptive neural fuzzy filter (ANFF), based upon neural network's learning ability and fuzzy if-then rule structure is proposed in this paper. The ANFF is inherently a feedforward multilayered connectionist network which can learn by itself according to numerical training data or expert knowledge represented by fuzzy if-then rules. The adaptation here includes the construction of fuzzy if-then rules (structure learning), and the tuning of the free parameters of membership functions (parameter learning). There are no hidden nodes (i.e., no membership functions and fuzzy rules) initially, and both the structure learning and parameter learning are performed concurrently as the adaptation proceeds. Two major advantages of the ANFF are: 1) a priori knowledge can be incorporated into the ANFF which makes the fusion of numerical data and linguistic information in the filter possible; and 2) no predetermination, like the number of hidden nodes, must be given, since the ANFF can find its optimal structure and parameters automatically. To demonstrate the performance of the ANFF, two applications, the nonlinear channel equalization and the adaptive noise cancellation, are simulated.

View description>>
A new direct sequence spread spectrum scheme for ISM band Radio Local Area Networks using BPSK modulation and matched filter receivers is presented. It employs an optimized 22-chip sequence whose two 11-chip segments are alternately used as spreading sequences for adjacent symbols. Owing to the low cross-correlation between the two 11-chip segments, the inter-symbol interference caused by long delays in multipath channels is significantly reduced. In the paper, a receiver structure using the optimized sequence and time diversity is described and simulation results are given. Compared with the schemes using the short 11-chip Barker code and long M-sequences, the new scheme offers superior system performance.

Describes a software development trial to evaluate the use of a groupware support environment for widely geographically separated software development teams. A four-person dislocated team, working in (simulated) disjoint time zones, was assigned a development task to carry out over a two-week period. Due to the time and location displacement, the developers were denied almost all opportunities for synchronous communications and had to rely on support from a prototype software engineering support system developed in Lotus Notes for interactions and coordination. In addition, the tasks in the trial were allocated such that productivity gains could be experienced through positive exploitation of time-zone differences, effectively giving around-The-clock working. This paper describes the design and organisation of the trial, reports on the progress of the trial, and presents both quantitative and qualitative results regarding the use of the Notes prototype.

© Springer-Verlag Berlin Heidelberg 1996. It is reasonable to say that so far neural networks have performed very well on many specific tasks of reasonable size, but their performance is far from satisfactory when applied to realistic but complex tasks such speech recognition and language processing. Yet the brain can perform these tasks efficiently and effortlessly (seemingly) using its optimized mechanisms. It is believed crucial to discover these mechanisms. In this paper, a neural network model of the isocortex as basic building block of intelligent systems is consolidated. The model incorporates mechanisms extracted from cortical circuit as suggested from the study of neuroanatomy. The learning rule compatible with what is known about synaptic adaptation in the neocortex is introduced. Simulations results, which verify the mathematical proof of the model stability and robustness, are presented.

34 dB waveguide gratings written by ultraviolet (UV) exposure of germanosilicate rib waveguides grown by plasma enhanced chemical vapour deposition (PECVD) and without the use of hydrogen loading are reported. The waveguide structure consists of 3 μm of 20% (mole fraction) Ge doped SiO 2 over a 15 μm thick cladding layer of pure SiO 2 grown on a silicon substrate. Standard photolithography and reactive ion etching techniques were used to fabricate the rib waveguides. The gratings show a maximum extinction ratio of 34 dB and 30 dB for TE and TM modes, respectively. These are the strongest gratings to date. This demonstrates the potential of PECVD as a growth technique for photonic integrated circuits used in wavelength division multiplexing (WDM).

A one-shot linear decorrelating detector(LDD) for the detection of asynchronous CDMA is presented. By treating every user as two independent users and using maximal ratio combining, a bit-by-bit detection is obtained. By applying a phase estimation algorithm on the output of the one-shot LDD, it is shown that the proposed detector can be used for the detection of asynchronous CDMA without the knowledge of carrier phase of any user. Simulation results show that the performance of the proposed detector approaches that of the optimum detector for single user transmission.

© 1997 ACM. Fostering an interest in Information Technology (IT) in school students is important both for the IT industry and for universities: We therefore enthusiastically welcomed the opportunity to hold an Information Technology vacation school for year 12 students in April 1996. Initiated and sponsored by the Australian Computer Society and Rotary International, the school enabled 60 secondary students who were in the process of making decisions about tertiary study to spend three days participating in a variety of computer-related activities at The University of Queensland Department of Computer Science, and experiencing life as a university student. The students developed skills in programming in Smalltalk, and using information systems and Internet resources. In addition, they visited other departments on campus and companies in the city to see a variety of uses of IT. We hoped to give the students the opportunity to make an informed decision about their future careers. A follow-up survey in early 1997 revealed that 80% of the students felt that attendance at the school helped them with their post-school career decisions. This paper describes our experiences with running the school: The program, components, feedback, and future plans. It was a very rewarding and worthwhile experience: We hope that this paper will encourage other universities to attempt similar programs.

Abstract
This article describes strategies and algorithms used to steer an unconventionally configured vehicle with twelve continuously controllable degrees of freedom. The WAAV vehicle is a laboratory scale prototype of a vehicle configuration first conceived and studied in simulation as a Mars roving vehicle. It’s configuration is quite different from an automotive vehicle and requires different approaches to directional control. The work described here is restricted to smooth, level terrain, but will be generalized for use on arbitrary, rough terrain.

In this work, an attempt is made to estimate the (AOA) Angles-of-Arrival) of multipath signal propagation in both azimuth and elevation inside a classroom and a convention hall using partially smoothed MUSIC (Multiple Signal Classification) algorithm. The MDL (Minimum Descriptive Length) criterion is used to decide the number of significant multipath components. The algorithms used in obtaining AOA from measured data are validated by computer simulations. Measurement results indicate that for the same transmitter power, a small room has more significant multipath reflections than a big room and such multipath reflections decrease as the distance between the transmitter and a receiver increases.
