Fuzzy reasoning can provide techniques both for representing and managing the imprecision in commonsense reasoning. But, like human reasoning, it conduces to inconsistencies (inherent to the imprecise or incomplete knowledge) that might be solved in the frame of fuzzy logic, simulating human behavior. In this paper we analyze this kind of conflicts and propose a non-monotonic fuzzy logic in order to solve it. Moreover, we show that many (non-monotonic) human reasoning patterns can be modeled by means of this "non-monotonic fuzzy reasoning". © 1998 Elsevier Science B.V.

LEO satellites present widely varying signal conditions. Fixed modulation schemes are designed for the worst operating conditions and cannot take advantage of the better signal to noise conditions present at high elevations. An adaptive modulation scheme, which used different constellation patterns with trellis coded modulation and a Reed Solomon Code outer code is proposed. The system is tested under AWGN noise and Rician/Rayleigh fading conditions. The system is found to provide good performance in AWGN and moderate fading conditions.

View description>>

The role of the dopamine D1 receptor subtype in alcohol-seeking behaviors was studied in mice genetically deficient in dopamine D1 receptors (D1-/-). In two-tube free choice limited (1-5 h) and continuous (24 h) access paradigms, mice were exposed to water and increasing concentrations of ethanol (3%, 6% and 12% w/v). Voluntary ethanol consumption and preference over water were markedly reduced in D1-/- mice as compared to heterozygous (D1+/-) and wild-type (D1+/+) controls, whereas overall fluid consumption was comparable. When offered a single drinking tube containing alcohol as their only source of fluid for 24 h, D1-/- mice continued to drink significantly less alcohol than D1+/+ and D1+/- mice. Dopamine D2 receptor blockade with sulpiride caused a small but significant reduction in alcohol intake and preference in D1+/+ mice and attenuated residual alcohol drinking in D1-/- mice. Dopamine D1 receptor blockade with SCH-23390 very effectively reduced alcohol intake in D1+/+ and D1+/- mice to the level seen in untreated D1-/- mice. These findings suggest involvement of both dopamine D1 and D2 receptor mechanisms in alcohol-seeking behavior in mice; however, these implicate D1 receptors as having a more important role in the motivation for alcohol consumption.

Home training in self-lowering of blood pressure using continuous blood pressure feedback has not previously been reported. Enhancement of laboratory-learned skills was hypothesized on the basis of outcomes from other intellectual, emotional and physical endeavours. To examine the supplementary effect of home blood pressure biofeedback training. Thirty unmedicated, mild hypertensives participated in a randomized, double-blinded, modified contingency placebo-controlled study. After suitable screening and baseline blood pressure measurements subjects undertook eight laboratory biofeedback sessions and then 12 home training sessions over 4 weeks using continuous finger blood pressure monitoring. In the laboratory those being administered active therapy (n = 16) lowered systolic pressures by 5 +/- 5.4 mmHg compared with a lowering of 4 +/- 4.2 mmHg with placebo (NS), During the fourth week at home lowering for the active group (11 +/- 8 mmHg) was greater than that with placebo (4 +/- 6.2 mmHg, P = 0.017), Arm-cuff blood pressures were not statistically different for groups and with time but that of the active group was lower by 9 +/- 15.4/7 +/- 0.2 mmHg, which is a clinically relevant change, after home biofeedback. The efficacy of self-lowering of systolic blood pressure in mild hypertensives by continuous feedback was enhanced by 6 mmHg with 4 weeks of practice at home. Standard arm-cuff blood pressure was reduced by a clinically relevant amount The home environment proved cost effective for this 'high-tech' approach.

Adult patients with GH deficiency have reduced lean body mass (LBM), muscle mass, and muscle strength, suggesting an underlying abnormality of protein metabolism. As acute GH administration has previously been reported to decrease protein oxidation and increase protein synthesis in GH-deficient (GHD) adults, we investigated whether the converse might occur in untreated GH deficiency by undertaking studies of whole body protein turnover in 10 GHD and 13 normal subjects using a 3-h primed constant infusion of 1- [13C]leucine. Dual energy x-ray absorptiometry was used to quantify LBM and fat mass (FM). In normal subjects, LBM was the major, independent determinant of leucine appearance (Ra; r = 0.80; P = 0.0009), leucine oxidation (r = 0.81; P = 0.0008), and leucine incorporation into protein (r = 0.75; P = 0.003). However, in an analysis of covariance, FM was also a significant independent determinant of leucine Ra (P = 0.002) and leucine incorporation into protein (P = 0.003). After correcting for LBM and FM, GHD patients had significantly reduced rates of leucine Ra (109.9 ± 4.4 vs. 125.5 ± 3.7 μmol/min, respectively; P = 0.02) and leucine incorporation into protein (87.0 ± 3.9 vs. 100.3 ± 3.3 mmol/min; P = 0.02) compared to normal subjects. There was no significant difference in the corrected rates of leucine oxidation between the two groups (22.9 ± 1.3 vs. 25.2 ± 1.0, GHD vs. normal; P = 0.20). In summary, GHD adults have reduced rates of protein synthesis and protein breakdown, but normal rates of irreversible oxidative loss; these findings are discordant with what was predicted from the acute changes in protein metabolism observed with GH administration. We conclude that normalization of protein oxidation may be a homeostatic mechanism that operates to constrain protein loss in GHD adults.

This paper discusses the solving of the algebraic Riccati equations and the Lyapunov matrix equations for large-scale systems with symmetric circulant structure. It is shown that the solving of the algebraic Riccati equations and the Lyapunov matrix equations for such a system can be simplified by solving N/2+1 independent equations of dimension N times smaller than the original equations. As an application, the problems of the linear quadratic optimal control and the robust linear quadratic optimal control for such a system can also be simplified.

To assess the relative contribution of genetic and environmental factors (particularly androgens) on circulating levels of lipid fractions, serum androgen and lipid fractions were measured in 34 pairs of female-female twins aged from 15-45 years, some of whom were discordant for polycystic ovary syndrome (PCOS) diagnosed by ultrasound. Nineteen pairs were monozygotic twins (MZ) and 15 pairs were dizygotic twins (DZ). Five pairs of MZ and 6 pairs of DZ were discordant for scan-PCO. We measured serum concentrations of total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglycerides (TRIG), lipoprotein (a) [LP(a)], and apolipoprotein B (apo B). Also, testosterone (T), dehydroepiandrosterone sulphate (DHEAS), sex hormone binding globulin (SHBG) and 3α-androstanediol glucuronide (3α-diol G) levels were measured. Transabdominal ultrasound was performed. Serum levels of TC, HDL-C, TRIG, LP(a) and apo B in the twins with PCO were not significantly different from the levels in their matched co-twins with normal ovaries. There were no significant correlations between androgen-hormones including T, DHEAS and 3α-diol G with any of the lipid measurements. Body mass index (BMI) was positively correlated with TRIG, LP(a) (both p < 0.05) and negatively correlated with HDL-C (p < 0.001). SHBG was negatively correlated with TRIG and LP(a) and positively associated with HDL-C (p < 0.05). Insulin was significantly correlated with TRIG (p < 0.001) and negatively with HDL-C (p < 0.01). The MZ intraclass correlation exceeded that of the DZ for all the lipid variables measured. The heritability estimates for LP(a), apo B, TC and HDL-C were 0.95, 0.56, 0.48 and 0.54, respectively. However, the intraclass correlation coefficient for TRIG was not significantly different between MZ and DZ but maximum likelihood analysis indicated that at least 10% of the variance of circulating TRIG concentration is determined by genetic factors. We conclude that twins discordant for PCOS...

The non-linear response of a two-degree-of-freedom nonlinear vibrating system subject to parametric excitation is examined for a two to one internal resonance and one-half subharmonic parametric resonance. The method of multiple scales is used to determine the amplitude-and phase-modulation equations to the first order. The coupled mode steady-state solutions are obtained from the trivial solution through pitchfork bifurcation. The Melnikov method is used to study the global bifurcation behavior while the critical parameter is determined for which the dynamical system possesses a Smale horseshoe type of chaos.

The development of the first Australian C-band polarimetric/Doppler meteorological radar system (C-POL) is described. Motivated by the need to obtain improved rainfall estimation and the vertical profile of hydrometeors, C-POL was developed jointly by the Bureau of Meteorology (BOM), the Commonwealth Scientific and Industrial Research Organisation of Australia, and the National Center for Atmospheric Research. C-POL is based on a standard operational C-band radar employed by the BOM but modified to be capable of transmitting linear horizontal and vertical polarizations and receiving the co- and cross polarizations on a pulse-to-pulse basis. Standard variables extracted include horizontal reflectivity (ZHH), radial velocity (Vr), spectral width (συ), differential reflectivity (ZDR), differential phase shift (ΦDP), and zero lag correlation coefficient [ρHV(0)]. With the addition of a second receiver chain, the linear depolarization ratio will soon be available. Initial results with the radar are discussed to give examples of the data quality, as well as some of the problems inherent in using a C-band radar in the Tropics.

We report here the cloning of the human GALR2 and GALR3 genes, an initial characterization of their pharmacology with respect to radioligand binding and signal transduction pathways, and a profile of their expression in brain and peripheral tissues. Human GALR2 and GALR3 show, respectively, 92 and 89% amino acid sequence identity with their rat homologues. Radioligand binding studies with 125I-galanin show that recombinant human GALR2 binds with high affinity to human galanin (K(D) = 0.3 nM). Human GALR3 binds galanin with less affinity (IC50 of 12 nM for porcine galanin and 75 nM for human galanin). Human GALR2 was shown to couple to phospholipase C and elevation of intracellular calcium levels as assessed by aequorin luminescence in HEK-293 cells and by Xenopus melanophore pigment aggregation and dispersion assays, in contrast to human GALR1 and human GALR3, which signal predominantly through inhibition of adenylate cyclase. GALR2 mRNA shows a wide distribution in the brain (mammillary nuclei, dentate gyrus, cingulate gyrus, and posterior hypothalamic, supraoptic, and arcuate nuclei), and restricted peripheral tissue distribution with highest mRNA levels detected in human small intestine. In comparison, whereas GALR3 mRNA was expressed in many areas of the rat brain, there was abundant expression in the primary olfactory cortex, olfactory tubercle, the islands of Calleja, the hippocampal CA regions of Ammon's horn, and the dentate gyrus. GALR3 mRNA was highly expressed in human testis and was detectable in adrenal gland and pancreas. The genes for human GALR2 and 3 were localized to chromosomes 17q25 and 22q12.2-13.1, respectively.

The effect of particle size and ionic strength of the feed suspension on critical flux was studied. The critical flux was defined in two different ways (strong and mild definition). The fouling, the increase of resistance (which is the basis of the mild definition of the critical flux) was relatively sensitive to the deposition of particles of 0.46 μm on the membrane of 0.2 μm mean pore. On the other hand, the deposition of large particles of 3.2 μm to a certain value on the membrane surface of 0.2 μm mean pore did not lead to the increase in resistance. In case of 11.9 μm particles, the transmembrane pressure did not increase even with significant amount of deposition of particles. The ionic strength of suspension had significant effect on the critical flux. For an ionic strength less than 1Ã10â1.5 M, there was a decrease in the critical flux. This could be due to the dense layer of deposit which is the result of less diffuse layer thickness of particles. Above this ionic strength, a significant increase in critical flux was noticed which may be due to the aggregation of particles.

In the crossflow microfiltration of particles, a deposit cake layer tends to form on the membrane and this usually controls the performance of the filtration process. This paper presents observations of particle deposition on membrane surfaces using a non-invasive, in situ, continuous direct observation through the membrane (DOTM) technique. The particles used in the experiments were typical of microfiltration processes, yeast (mean diameter 5 μm) and latex beads (3, 6.4 and 12 μm). The filtration tests were conducted in the imposed flux mode, so that the flux could be controlled at, below, or above the âcritical fluxâ. Below the critical flux, the particle deposition was negligible; near the critical flux the particle deposition was significant; and above the critical flux, particle layers were formed on the membrane surface. Rolling of the particles was observed during the filtration of 6.4 μm latex near the critical flux whereas a flowing cake layer was observed during the filtration of 3 μm latex. The particle size distribution of the deposited particles changed with the crossflow velocity, with smaller particles deposited on the membrane at higher crossflow velocity. Comparison of the normalised flux (J/ÎP) with the membrane area coverage by the particles revealed that for filtration of latex particles âflux percentage (with respect to the clean membrane)❠was marginally greater than the percentage of uncovered membrane area, whereas for filtration of yeast, the âflux percentage❠was significantly less than the uncovered area percentage due to the deposition of smaller cell debris species. This paper demonstrates that DOTM is a powerful technique for the study of fundamentals of particle deposition and interactions between the particles and the membrane.

A new radiation-type waveguide-to-waveguide coupler is proposed. The coupling is realized through gratings embedded on the dielectric waveguides involved. Compared to the conventional hybrid-mode coupler, this type of coupler has advantages in that the two waveguides can be quite dissimilar as well as being separated by large distances. It is demonstrated that the coupling performance of this radiation-type coupler can be enhanced significantly by using photonic bandgap (PBG) structures.

We report the cloning of a novel human gene (GPR32) encoding a putative G-protein-coupled receptor (GPCR) of 356 amino acids and a related pseudogene ψGPR32. The deduced amino acid sequence of GPR32 shares 35-39% identity with members of the chemoattractant receptor family. ψGPR32 shares 93% nucleotide identity with GPR32. We identified a mouse EST encoding a putative GPCR (GPR33) of 309 amino acids. The deduced amino acid sequence of GPR33 shares 30-35% identity with members of the chemoattractant receptor family and 36% identity with the receptor encoded by GPR32. The human orthologue of GPR33 contains a single basepair substitution with respect to the mouse, resulting in the presence of an in-frame stop codon within the predicted second intracellular loop, demonstrating that it is a pseudogene. Through fluorescence in situ hybridization and physical mapping of YACs, both GPR32 and ψGPR32 were mapped to chromosomal 19, region q13.3, while ψGPR33 was mapped to chromosome 14q12.

A treatment technology known as "a combined system of floating medium and sand filter (FMSF)" was developed and tested successfully with prawn farm effluent. This system has a remarkable techno-economical advantages. Laboratory and semi pilot-scale studies were carried out to optimise the filter bed depth, backwash method and other operating conditions. The dewatering characteristics of sludge from filter backwash was also analysed. The filter was operated at a high rate. The experimental results indicated that: (i) in case of no in-line chemical addition, the smaller ratio between floating medium and sand filter depth gave rise better filter performance. At the filtration rate of 7.5 - 20 m3/m2.h and with an in-line chemical addition, the suitable depth of floating medium varied from 400-1000 mm for a sand filter depth of 400 mm; (ii) frequent (once in every 90-120 minutes) but short duration of backwash (not more than 60 seconds) was found to be suitable. During the backwash, the water and air were sent for 30 seconds in upward direction and then followed with upflow of water for another 30 seconds. Backwash water amount comprised only 1.2-1.8% of the filtered water production. A mechanical backwash system using rotating paddles is a promising alternative for floating medium filter; and (iii) the filterability of the sludge from filter backwash was low in case of no in-line chemical addition (specific resistance, r = 9.34 1010 m/kg) but improved with in-line flocculant addition (r = 3.07 109 - 1.29 1010 m/kg).

We report here the molecular cloning, tissue distribution, and chromosomal localization of novel genes encoding G-protein-coupled receptors (GPCRs). A search of a mouse database of expressed sequence tags revealed an EST partially encoding a GPCR, which was used to screen a mouse genomic library to obtain the translational open reading frame (ORF). The resultant clone, GPR27, contained an intronless ORF, encoding a receptor of 379 amino acids. In an alternate strategy, human genomic DNA was subjected to polymerase chain reaction (PCR) amplification, using degenerate oligonucleotides based on GPR1. Two PCR products partially encoding GPCRs were isolated and used to screen a genomic library to obtain the translational ORF. One of the resultant clones, GPR30, contained an intronless ORF encoding a receptor of 375 amino acids. The other clone, GPR35, also contained an intronless ORF encoding a receptor of 309 amino acids. Transcripts corresponding to GPR27 and GPR30 were detected in several areas of human and rat CNS, while GPR35 expression was detected only in the rat intestine. Through fluorescence in situ hybridization analysis the gene encoding GPR30 was localized to chromosome 7p22 and GPR35 to chromosome 2q37.3.

A multicarrier direct sequence code division multiple access (MC-DS-CDMA) technique is proposed for point-to-multipoint communication systems. Time delays and related interference phenomenon are discussed and multicarrier techniques for mitigating multipath effects are highlighted. An independent two-ray multipath model is used for determining the major channel effects that influence multicarrier DS-CDMA. In particular, time dispersion and frequency distortion are examined in terms of their effect on multicarrier modulation schemes. Empirical simulated analysis is presented for additive white gaussian and multipath channels in order to highlight the bandwidth efficiency, interference generation and the bit error rate (BER) of multicarrier DS-CDMA under selected multipath configurations. Coding strategies are discussed for mitigating multipath induced errors and their expense on the bandwidth efficiency is emphasized.

In developing countries there is an increasing demand for telecommunications and Internet access. The current problem, especially in Africa, is to find solutions which can provide underdeveloped countries with a satisfactory network. This requires a relatively fast roll-out at low-cost. Modern wireless system claim to offer quick and easy deployment. However, in many cases the wireless system deployment is delayed because adequate radio plans have to be designed, and they are not optimized for Internet and computer communications. Multihop packet radio can offer computer communication in an easily deployable ad-hoc wireless network which does not require frequency planning. However, voice traffic is not easily implemented on packet radio networks due to the bursty and delayed traffic characteristics. A multihop packer radio network is proposed which offers voice and Internet communications.

Estimating a channel impulse response using a known aperiodic sequence is considered. The problem can be reduced to minimizing the trace of the inverse of a Toeplitz matrix. An efficient algorithm for computing this trace is developed and optimal binary sequences up to length 32 are found and tabulated. The use of complementary sequences in this context is also investigated. It is shown that the eigenvalues of the autocorrelation matrices of a pair of complementary sequences sum to a known constant.

View description>>

This paper concerns dynamic team formation in multi-agent systems, where each agent determines its own action by observing the other agents. The test bed is a simple pursuit game. Identical mobile agents learn to form teams to most effectively catch individual stationary targets. The decision-making component is not manually encoded, but instead it self-learns, without an external teacher, by the method of temporal differences. Agents do not negotiate, nor do they explicitly form or communicate commitments. Instead, agents determine their own actions by a behaviourist approach: they reason only from the relative positions of other agents, not from an interpretation of the intent of those other agents. Experimental results demonstrate that the agents do coordinate their activities, by forming teams, In this paper, self-organisation is manifested in three forms: the formation of teams by the pursuer agents, the temporal difference algorithm by which agents learn to cooperate, and in the representation of the learnt knowledge as the weights in a perception.

Objective: To investigate the ability of both clinical and environmental strains of Burkholderia cepacia, along with control strains of Pseudomonas aeruginosa and Escherichia coli, to invade a respiratory epithelial cell line, A549. Methods and Results: Using a double immunofluorescence labeling technique, a clinical strain of B. cepacia, C1359, and the clonally related strains A509 and J2315, were shown to invade A549 cells at a high level (2-8% A549 cells invaded) compared to environmental strains of B. cepacia NCTC 10661 and NCTC 10743 (0.5-1% of A549 cells invaded). Control strains of P. aeruginosa PAO1 and E. coli C600 did not appear to be able to invade respiratory epithelial cells using this method. Ceftazidime protection assays revealed that B. cepacia C1359 and NCTC 10743 were able to survive and multiply within A549 cells for > 24 h. In contrast, B. cepacia NCTC 10661, P. aeruginosa PAO1 and E. coli C600 failed to multiply within A549 cells, showing a significant decrease in numbers after 24 h. Conclusions: The ability to survive and multiply within respiratory epithelial cells may be an important virulence factor of B. cepacia infection in cystic fibrosis.

We extend the principles of cavity quantum electrodynamics to nuclei inside low-loss cavities. The resulting nucleus-cavity system exhibits spontaneous emission and internal conversion rates which differ radically from those of the individual components. The quantum mechanical derivations of these rates are given. The internal conversion process occurs via the exchange of a virtual photon between an excited nucleus and an electron bound to that nucleus. Even though the photon is virtual, partial suppression of the internal conversion process is shown to be theoretically possible. With a controlled modification of the internal conversion rate using a high- Q cavity, one can achieve a number of potentially interesting applications including an excited nuclear state containment unit, a nuclear battery, and a neutron detector. © Journal of Electromagnetic Waves and Applications.

The form of N supply is known to influence the uptake of other plant nutrients, notably phosphorus (P), through its effect on soil pH in the rhizosphere. A glasshouse study was conducted to test the effect of N form (NH4/+, NO3/-, or both) on the transformation of soil P in the rhizosphere and its availability to tea (Camellia sinensis L.) plants fertilised with sparingly soluble Eppawala phosphate rock (EPR). Four-month-old tea (TRI 2025) plants were grown in rhizosphere study containers containing an Ultisol from Sri Lanka (pH 4.5 in water) amended with EPR and KCl at 200 μg P or K/g soil, and mixed with (NH4)2SO4 (100% NH4/+-N), NH4NO3 (50% NH4/+-N and 50% NO3/--N), and Ca(NO3)2 (100% NO3/--N) at the rate of 200 μg N/g soil, with a control (no N fertiliser), as treatments. Rhizosphere pH decreased compared with the bulk soil when N was supplied as NH4/+ or NH4/+-NO3/- forms, and increased when N was supplied as NO3/-. The cation-anion balance estimations in the plants showed that the plants had taken up more NO3/- than NH4/+ even in (NH4)2SO4 treated soil, suggesting high nitrification rates, especially in the rhizosphere, in spite of using a nitrification inhibitor. More EPR dissolved in the rhizosphere compared with that in the bulk soil, regardless of the N form applied. The (NH4)2SO4 treatment had the highest dissolution rate of EPR in the rhizosphere, whereas Ca(NO3)2 treatment had the lowest, reflecting the degree of acidification in the rhizosphere. Resin-P and NaOH-P(i) (inorganic P) concentrations were lower and NaOH-P(o) (organic P) concentration was higher in the rhizosphere than in the bulk soil. Plant and possible microbial uptake of P is the main reason for the decrease in resin-P and NaOH-P(i). The increase in NaOH-P(o) concentration in the rhizosphere is believed to be due to transformatio...

Tea (Camellia sinensis L.) is generally grown in highly weathered acidic Ultisols of the humid tropics. The low pH, large P fixing capacity and moisture content of these soils favour the dissolution of phosphate rock. Plant species differ widely in their ability to take up P from phosphate rock, and we have compared phosphate mobilization in the rhizosphere of tea with that under calliandra (Calliandra calothyrsus L.), Guinea grass (Panicum maximum L.) and bean (Phaseolus vulgaris L.) by studying the changes in the concentration of P fractions at known distances from the root surface in an acidic (pH in water 4.5) Ultisol from Sri Lanka treated with a phosphate rock. Plants were grown in the top compartment of a two-compartment device, comprising two PVC cylinders physically separated by a 24-μm pore-diameter polyester mesh. A planar mat of roots was formed on the mesh in the top compartment, and the soil on the other side of the mesh in the lower compartment was cut into thin slices parallel to the rhizosphere and analysed for pH and P fractions. All plant species acidified the rhizosphere (pH [water] difference between bulk and rhizosphere soils was 0.17-0.26) and caused more rock to dissolve in the rhizosphere (10-18%) than in the bulk soil (8-11%). Guinea grass was most effective, though the rate of acidification per unit root surface area was least (0.02 μmol H+ cm-2) among the four species. Tea produced the largest rate of acidification per unit root surface area (0.08 μmol H+ cm-2). All species depleted P extracted by a cation-anion exchange resin and inorganic P extracted by 0.1 m NaOH. All except tea depleted organic P extracted by 0.1 m NaOH in the rhizosphere. The external P efficiencies (mg total P uptake) of Guinea grass, bean, tea and calliandra in soil fertilized with phosphate rock were 4.82 ± 0.42, 4.02 ± 0.32, 1.06 ± 0.02 and 0.62 ± 0.02, respectively, and the corresponding internal P efficiencies (mg shoot dry matter production per mg plant P) ...

View description>>

Default logic is a prominent rigorous method of reasoning with incomplete information based on assumptions. It is a static reasoning approach, in the sense that it doesn't reason about changes and their consequences. On the other hand, its nonmonotonic behaviour appears when a change to a default theory is made. This paper studies the dynamic behaviour of default logic in the face of changes, a concept that we motivate by a reference to requirements engineering. The paper defines a contraction and a revision operator, and studies their properties. This work is part of an ongoing project whose aim is to build an integrated, domain-independent toolkit of logical methods for reasoning with changing and incomplete information. The techniques described in this paper will be implemented as part of the toolkit.

Wireless ATM (WATM) will be used to support broadband applications for future generation mobile services. To achieve this, the existing ATM protocol must be augmented with mobility management capabilities. One of the important components of mobility management is the ability of the network to seamlessly re-route existing connections to different parts of the network. To date, a number of schemes have been proposed for broadband wireless networks. These schemes can potentially be used in WATM networks. In this paper, we compare the performance of these schemes in terms of their complexity, handover latency, communication disruption period and buffer and bandwidth requirements.

© 1998 IEEE. The latter part of the 20th century has seen significant changes and improvements in the design and practice of reflectorantennas. As well as traditional users of reflectors, such as defence, telecommunication utilities and radio astronomy, significant consumer markets have now opened up. For instance, it is common for many homes and offices to have a dish connected to a wall or roof. At the same time design techniques for reflectors and associated feed systems have also undergone change. Until a few years ago effectsthat were poorly modelled or completely ignored that can now be analysed include, reflectoredge diffraction, near-field effects, grid, composite and painted surfaces, accurate feed models, mutual coupling and scattering in feed arrays, and reflector/feedinteractions. Shaped reflectors are now widely used on satellite antennas, and dielectric-loaded horns are replacing corrugated horns in some earth station applications. It is the purpose here to outline some recent changes and improvements in the design and synthesis techniques used for reflectors and feeds.

Artificial Neural Networks (ANNs) have been successfully applied to Optical Character Recognition (OCR) yielding excellent results. In this paper a technique is presented that segments difficult printed and cursive handwriting, and then classifies the segmented characters. A conventional algorithm is used for the initial segmentation of the words, while an ANN is used to verify whether an accurate segmentation point has been found. After all segmentation points have been detected another NN is used to identify the characters which remain following the segmentation process. The C programming language, the SP2 supercomputer and a SUN workstation were used for the experiments. The technique has been tested on real-world handwriting scanned from various staff at Griffith University, Gold Coast. Some preliminary experimental results are presented in this paper.

The real potential of inversionless lasing lies in the utilization of mismatched schemes, leading to compact high-frequency laser sources. A comparative study of a matched and a mismatched system is made in which all parameters are made equal except the transition wavelengths. Theory is presented to relate the appropriate element of the resulting density matrix to the absolute absorption or gain that may be experimentally observed. This facilitates the study of possible atomic systems that may provide mismatched gain in a Doppler-broadened regime. Experimental investigations into the production of inversionless gain at 422 nm in a Doppler-broadened, mismatched rubidium system are reported.

The research work in Australia is funded collaboratively by the Australian Research Council and industry, and has involved both full scale serviceability and ultimate load testing (up to 12.2m) as well as an examination and analytical investigation into fundamental behaviour of cellular and âT❠beam structural forms constructed from timber elements. Several prototype bridge decks spanning up to 12.2m have been constructed and research is currently being undertaken to extend this technology to applications with clear spans of 25 to 30m. This paper presents a general overview of the R & D programs and applications of stress laminated timber technology in Australia, with an emphasis on the implications of âbuiltâup❠technology for timber bridges. A unique case study is presented in detail for the Hopkins River Bridge at Warrnambool, Australia, reviewing the research, design and construction aspects for a âbuiltâup❠deck superstructure based on both âTee / cellular❠forms and using incremental launching techniques. The paper concludes with discussion on the economic benefit of this new construction method.

© 1998 IEEE. Emerging trends in computer design attempt to include specific solutions for handling images also in general-purpose computers, because of the current spread of multimedia, image processing and computer graphics applications. In this context, we propose hardware pre-fetching techniques specific for caching images: The main issue we state is that most algorithms working on images exhibit a 2D spatial locality that is not taken into account in current cache organization and data access strategies. To this aim we propose an adaptive local pre-fetching for the image data type; this technique, mirroring the two-dimensional spatial locality of image processing algorithms, results in being more efficient than other approaches, such as sequential pre-fetching and adaptive pre-fetching. Performance is evaluated on different classes of image processing algorithms, namely raster-scan and propagative algorithms, common in computer vision and multimedia applications.

A decision directed adaptive antenna array for the uplink of CDMA cellular systems, which is based on a normalized least mean square algorithm (NLMS), is presented. The bit error ratio performance of the adaptive antenna in various scenarios, which include the use of transmission power control (TPC) and diversity combining, is studied. It is shown that the adaptive antenna outperforms the steering beam technique when the signal-to-noise ratio is large and the active users are clustered. However, the performance of the adaptive antenna becomes very similar to that of the steering beam when there are a large number of randomly distributed active users in the sector.

This architecture achieves improved prediction results on noisy and non-stationary data. In contrast to previous efforts the current system was designed with a particular emphasis on solving the problems of local overfitting & underfitting caused by non-stationarity and noise in the data. The cascade correlation constructive neural network training algorithm was used for the fast training of near optimal complexity global & local experts. The Kohonen Self Organizing Map was used to find regions of the data on which to train local experts. Improved results were obtained by using a combination of the outputs of the global & local experts.

The exhaust noise of a two-cylinder four-stroke diesel engine was experimentally investigated in order to examine the predictability of the exhaust noise to be reduced by a feedforward active control system. Special attention has been paid to the low frequency characteristics of the exhaust noise as low frequency noise is difficult to reduce with a conventional muffler but effective to control by active control technique. The periodicity of the exhaust noise was examined with the ensemble-average and ensemble-standard deviation of the exhaust pressure signals. The results showed that the exhaust noise investigated was basically quasi-periodic and its variation between cycles was acceptable with an adaptive control algorithm. The properties of the exhaust pressure in low frequency domain were analyzed with the spectra of the exhaust noise pressure. A method to estimate the instantaneous exhaust noise pressure proposed by the author in 1996 was applied to this diesel engine by estimating a limited number N of low frequency harmonics in terms of engine speed and load. This method matches the active control system by its fast response. The predicted and experimental results agree well and show that the prediction method is valid and the exhaust noise pressure is predictable with this method. © 1998 Society of Automotive Engineers, Inc.

Featherstone's method of articulated inertias makes such dynamic simulators reasonably efficient. However, rover vehicles often operate at low speeds that make the dynamic analysis unnecessary. A simpler approach is to use only velocity and position information to obtain the next state. Simulation on rugged terrain requires the program to account for gravitational and contact forces.

A TLM-based transform with variable time steps is employed in the simulation. This model can provide an accurate prediction of transformer performance and core losses and is suitable for simulation of high frequency switching mode converters using transformer isolated outputs. Some interesting issues such as stray capacitance, are discussed. Simulations of a 500 W transformer in a full bridge inverter operated at 15 kHz and 25 kHz have been confirmed by experiments.

© Springer-Verlag Berlin Heidelberg 1998. The ability to correctly analyse the impact of changes to system designs is an important goal in software engineering. A framework for addressing this problem has been proposed in which logical descriptions are developed alongside traditional representations. While changes to the resulting design have been considered, no formal framework for design change has been offered. This paper proposes such a framework using techniques from the field of belief revision. It is shown that under a particular strategy for belief revision, called a maxi-adjustment, design revisions can be modelled using standard revision operators. As such, the paper also offers a new area of application for belief revision. Previous attempts to apply belief revision theory have suffered from the criticism that deduced information is held on to more strongly than the facts from which it is derived. This criticism does not apply to the present application because we are concerned with goal decomposition rather than reasoning from facts, and it makes sense that goals should be held onto more strongly than the decompositions designed to achieve them.

The flow generated by a synthetic jet actuator is investigated experimentally and computationally. The experimental data and computational predictions show good agreement with the theory for a steady turbulent jet. It is found, however, that the synthetic jet establishes itself much more rapidly than the steady jet, and this is thought to be the result of turbulent dissipation causing a vortex to be trapped near the actuator orifice. Also, the optimal forcing frequency was found to be in agreement with a coupled fluid-structural interaction model.

© 1998 IEEE. Open systems, through the use of public, consensus based specifications or standards, are focussed on achieving the interoperability between, and the portability of components. In accommodating standards, open systems promise the advantages of plug-n-play technology, rapid prototyping and component re-use, while at the same time preventing system integration misfits, short system lifespan and difficulty in maintenance. In the development of open systems, it has been recognised that the specification and standardisation of interfaces, nor components, is of critical importance to realising these advantages. Due to the critical role of interfaces in open systems, the quality of the interface specifications used to engineer the interfaces is fundamental to the fulfilment of the promises of open systems. The authors contend that since current specifications and standards are deficient, then open complex computer systems, built using these specifications and standards, will indeed be no silver bullet. The authors present several ways forward, based on the inter-relationships between components, so that in the future the promises of open complex computer systems may still be fulfilled.

© 1998 IEEE. The finite-difference time-domain (FDTD) method is useful in many antenna applications because it facilitates modelling of complex structures and is capable of characterising antenna performance over a wide-frequency band. However, for antenna arrays of even modest size, the excessive computer storage and run-time may become prohibitive for design and optimisation purposes. Some work has been done with time-domain transform methods for computing weak coupling between antennas (Page et al. 1996). In this paper, an algorithm is developed using the Kirchhoff near-field to near-field transformation (Shlager and Smith, 1995) for the one-way coupling between antenna elements. This coupling representation is then applied to arrays in a manner analogous to an element-by-element analysis in the frequency domain, except that in the method described here the coupled currents at the antenna-feed ports are added in the time-domain so as to permit the introduction of true-time delays for wide-band beam steering. The advantages of the transform method over a full FDTD method are smaller computer storage and a reduction in late-time FDTD effects associated with reflections from the absorbing boundary on the outer surface of the computational domain and also from numerical dispersion and instabilities.

© Springer-Verlag Berlin Heidelberg 1998. Logic-based approaches to reasoning about actions, change and causality, highlight efficient representation and processing of domain background knowledge as an important task. Action theories recently developed in the framework of action languages with inertia and ramifications [20,14] not only adopt the principle of minimal change reinforced with the policy of categorisation (assigning different degrees of inertia to language elements) but also try to incorporate background causal knowledge. In this paper we aim to trace the evolution of action languages and to explore interactions between ontological characteristics of action domains such as inertia and causality. Such an analysis should clarify how possible solutions to the frame and the ramification problems are affected by applying the policy of categorisation to causal' domains. We first attempt to identify conditions (more precisely, restrictions) which preserve the meaning of domain descriptions when moving among various analysed languages. Relaxing such restrictions can help in evaluating the role of the frame concept (and policy of categorisation, in general) in an action language with fluent-triggered causality.

© 1998 IEEE. The simplest drive for a permanent magnet motor is a three-phase bridge inverter switched according to the six-step, »120° conduction» algorithm. For the more complicated, higher frequency, switching algorithms which give (approximately) a sinusoidal current, phasor analysis of the per-phase equivalent circuit provides a simple accurate description of the phase current and voltage, at least for a motor with near-sinusoidal back-emf and near-uniform inductance. But for six-step switching, there are no well-known general formulae, even describing the relationship between applied DC voltage and motor no-load speed. This paper presents exact analytic phasor analysis for six-step, 120° conduction switching of permanent magnet motors with sinusoidal back-emf. Formulae are given for the fundamental components of voltage and current and for the inferred torque. These formulae enable the DC voltage and the switching advance angle to be determined to operate the motor at any desired torque, speed and fundamental current advance angle. In particular, it is frequently desired to operate the motor with minimum copper loss for a given torque. The copper loss will be close to minimum if the current fundamental is aligned with the back-emf. Using the formulae presented in the paper and a two-dimensional root-finding algorithm, the required switching angle and commutation angle can be determined and the DC link voltage inferred. The paper thus allows simple phasor analysis theory to be translated into six-step switching prescriptions.
