FSH is a glycoprotein hormone required for the development and maturation of the ovarian follicle and for spermatogenesis. FSH is glycosylated at asparagine residues 52 and 78 on the α-subunit and residues 7 and 24 on the β-subunit. In vitro, the carbohydrate residue at position α 52 is required for signal transduction. To define the contribution of the carbohydrate residues to FSH potency in vivo, we assessed the MCR and in vivo bioactivity of site-specifically deglycosylated recombinant human FSH variants. The removal of the β-subunit carbohydrate residues significantly (P < 0.05) affected the MCR and resulted in significantly (P < 0.05) reduced in vivo bioactivity. For all recombinant human FSH variants, a strong correlation (r = 0.90; P < 0.01) was observed between MCR and in vivo potency, indicating that the circulatory half-life of the hormone appears to be the primary determinant of in vivo bioactivity. Although the β-subunit carbohydrate residues have the greatest effect in determining FSH potency in vivo; the α 52 residue, important in vitro, has no effect on either MCR or in vivo potency. This study highlights the difficulties of translating in vitro results to whole animal physiology. © 1995 by The Endocrine Society.

The onset of apoptosis is often coincident with internucleosomal DNA fragmentation or ladders which are considered a hallmark of the process. However, several studies have indicated that MOLT-4 human lymphoblastoid cells exposed to various agents, including VP16, display some apoptotic characteristics in the absence of either internucleosomal ladders or production of apoptotic bodies. The present study records that, in the presence of aurintricarboxylic acid (ATA), internucleosomal ladders were detected in DNA isolated from VP16-treated MOLT-4 cells; a paradoxical result in view of inhibition by ATA of nuclease activity in cell free preparations. The activity of ATA in mediating genomic fragmentation was dose- and time-dependent. Moreover, addition of ATA to VP16-treated MOLT-4 cells also resulted in production of apoptotic bodies, this effect being quantified by morphological examination and flow cytometry. Detection of ladders and apoptotic bodies after addition of ATA was not attributable to increased toxicity in cells exposed to the combined treatment relative to VP16 alone. A similar response, that is the appearance of both internucleosomal fragmentation and apoptotic bodies, occurred after exposure of MOLT-4 cells to the mitotic inhibitor podophyllotoxin. The consistent association between internucleosomal fragmentation of DNA and formation of apoptotic bodies exhibited during death of MOLT-4 cells, insofar as both characteristics are either present or absent following different agents, suggests interdependence. © 1995 Academic Press, Inc.

A method of force allocation by optimizing the friction angles at finger contacts was combined with the computed torque method to find the torques to be commanded at finger joints for multifingered systems. In this way, slip can be avoided when the object is grasped or manipulated. The proposed method can be used to efficiently find the input torques, and is applicable for real-time computation. A history-based method is also proposed to improve the smoothness of the input torque commands. Three-dimensional simulation results are given.

New telecommunications services have emerged which will place quite disparate processing demands on the control systems of exchanges and the optimal system configuration will depend on the call mix to be supported by the exchange. A cost effective distributed control system design in the ISDN and IN environments can be achieved by combining optimal placement of software functionality and optimal choice of capacities for the processing elements. Two control system models based on queueing networks and able to capture the features of the system at different levels of detail are developed and used to produce distributed control system optimisation algorithms. These algorithms can assist system designers in producing optimal control systems which are required to satisfy particular uniform load specifications and performance constraints. Simple examples indicate the range of applicability of the developed algorithms.

A rectangular dielectric-resonator antenna, fed by a microstripline through an aperture, is analysed using the finite-difference time-domain method. The antenna operates in the TE1δ1 mode and radiates like a magnetic dipole. The electric and magnetic fields in and around the antenna are presented for various time steps. The radiated far-field waveforms are calculated in several directions, by applying the field equivalence principle directly in the time-domain. The frequency-domain far-field patterns are presented at the resonant frequency. They are similar to the far-field patterns of an elemental magnetic dipole, and compare well with previously measured far-field patterns of a rectangular dielectric-resonator antenna.

A one-dimensional zonal reflector is a conducting surface which is uniform in one direction and has a zonal profile in the other. Similar to a cylindrical reflector, it converts a cylindrical wave from a line-source into an outgoing plane wave. In this paper, the radiation performance of such reflectors with TM-wave illumination is analyzed by the method of moments (MoM). The influence of corner diffraction and zoning on the sidelobe level is investigated. Three types of configurations are considered, which include the parabolic zonal reflector and two stepwise zonal reflectors of different configurations. It is found that corner diffraction makes a significant contribution to the sidelobe level, but zoning intrinsically raises the far-out sidelobes. Numerical results show that the near-in sidelobes of the stepwise zonal reflector can be significantly decreased by adjusting the geometrical configuration. © 1995 IEEE

With a fixed substrate and a given operating frequency, the phase shift is determined by the array parameters. In the paper, the spectral domain moment method model for analyzing homogeneous reflective phase shifters with conducting rings as elements is presented, and numerical and experimental results are given. A novel phase correcting Fresnel zonal reflector based on this model is reported. A 43% maximum antenna efficiency and -22 dB sidelobe level were measured in X-band. The bandwidth of the reflector is estimated to be greater than 10%. © 1995 IEEE

We have cloned and mapped the chromosomal location of three novel human genes encoding G protein-coupled receptors that we have named GPR6, GPR5, and GPR4. The entire coding region for each of these genes was contained on single exons. Gene GPR6 encoded a receptor that shared closest identity (71% in the transmembrane regions) with the human orphan receptor GPR3 and was localized to chromosome 6 (q21–q22.1). Northern blot analysis revealed that GPR6 transcripts were abundant in the human putamen and to a lesser extent in the frontal cortex, hippocampus, and hypothalamus. Gene GPR5 encoded a receptor that most closely resembled the orphan receptor RBS11 (48% in the transmembrane regions) and the MIP 1α/RANTES receptor (45% in the transmembrane regions) and was localized to chromosome 3 (p21.3–p21.1). Gene GPR4 shared identity (40% in the transmembrane regions) with the human platelet-activating factor receptor and was localized to chromosome 19 (q13.2–q13.3). © 1995, Mary Ann Liebert, Inc.

Common vitamin D receptor (VDR) gene alleles have recently been shown to contribute to the genetic variability in bone mass and bone turnover, however, the physiological mechanisms involved are unknown. To examine this, the response to 7 days of 2 micrograms oral 1,25-dihydroxyvitamin D[1,25-(OH)2D] (calcitriol) stimulation was assessed in 21 premenopausal women, homozygous for one or other of the common VDR alleles (bb, n = 11; BB, n = 10). Indices of bone turnover and calcium homeostasis were measured during 2 weeks. Baseline osteocalcin, 1,25-(OH)2D, type I collagen carboxyterminal telopeptide, and inorganic phosphate levels were significantly higher and spinal bone mineral density was significantly lower in the BB allelic group. After calcitriol administration, similar levels of 1,25-(OH)2D were attained throughout the study in both genotypic groups. The increase in serum osteocalcin levels in the BB group was significantly less than that in the bb group (11% vs. 32%, P = 0.01). The genotype-related baseline difference in osteocalcin levels was not apparent at the similar serum 1,25-(OH)2D levels. By contrast, the baseline differences in phosphate and type I collagen carboxyterminal telopeptide persisted throughout the study. Serum ionized calcium levels did not differ between genotypes, nor did it move out of normal range values. However, parathyroid hormone was less suppressed in the low bone density group (38% vs. 11%, P = 0.01). These data indicate that the VDR alleles are associated with differences in the vitamin D endocrine system and may have important implications in relation to the pathophysiology of osteoporosis.

Acid sulphate soils are formed when pyrite within a soil layer is oxidised, generating sulphuric acid. The oxidation of pyrite often results in yellow mottles of jarosite. The pH levels in greatly affected areas are often less than 4.0, and the associated environmental impacts include fish kills, retarded growth of crops and changes in water chemistry. Certain regions of acid sulphate soils along the South Coast of NSW are of much concem, because of limited land available for food production and cash crops. This study quantifies the effect of changes of the groundwater table on the acidity of the coastal flood plain in Berry, located on the Illawarra coastline, New South Wales. Based on several boreholes and drain sites, the existence of jarosite was verified, characterising the study area as a potential acid-sulphate soil region. The field investigation of the study area included the monitoring of groundwater and drain water quality, including the pH and aluminium levels. The study shows convincingly that the increase in groundwater level is effective in preventing adverse pH and aluminium levels. © 1995 Springer-Verlag.

View description>>
OBJECTIVE: To describe the relationship between spinal degenerative disease and bone density in the elderly both cross sectionally and longitudinally. METHODS: Random population based sample of 113 men and 187 women over 60 yrs of age participating in the Dubbo Osteoporosis Epidemiology Study (a longitudinal population based study of fracture risk factors) who had bone density measured on 2 occasions (average interval 2.5 yrs) and spinal radiographs on one occasion (performed according to a standardized approach). RESULTS: Spinal degenerative disease, of varying severity, was common in this population (osteophytes 69%, disc narrowing 67%, posterior element disease 99%). Scores for osteophytosis, disc narrowing, and posterior element disease (together with age and body mass index) independently explained 43% of the variation in spinal bone density in men (p < 0.00001) and 26% in women (p < 0.00001). The rate of change at the spine increased with increasing severity of osteophytosis in both men (p = 0.03) and women (p = 0.05), but not the other measures, and the total amount of variation explained by these measures was modest. In comparison, severity of spinal degenerative disease had only a modest but significant relationship with femoral neck bone density in both sexes, but not its rate of change. Subjects with any degree of osteophytosis had higher bone density compared to those without osteophytes at both the lumbar spine (men 21% higher, 95% CI 12-31; women 16% higher, 95% CI 9-23) and, to a lesser extent, femoral neck (men 12% higher, 95% CI 4-20; women 6% higher, 95% CI 1-13). Vascular calcification had no relationship with bone density at either spine or hip. CONCLUSION: Spinal bone density measurement and its sequential followup may be erroneous in the elderly due to concomitant degenerative disease. Bone density at the femoral neck was much less affected by spinal degenerative disease, which suggests that this site may be more efficacious for both monitor...

OBJECTIVE: Osteoarthritis (OA) is associated with an increase in bone density both locally and at distant sites. Prospective data are limited on the relationship between OA and fracture. We studied the possible relationship between self-reported OA, bone density, postural stability measures, and atraumatic fractures as part of a study of men and women over 60 years of age. METHODS: Subjects were part of the Dubbo Osteoporosis Epidemiology Study (a longitudinal population based study of fracture risk factors). Bone density was measured by dual energy x-ray absorptiometry. Postural stability was assessed by the validated measures of quadriceps strength and sway. Medication use and self-reported arthritis were assessed by a structured personal interview. Fractures were ascertained retrospectively by interview and prospectively by viewing radiographic reports for fracture. RESULTS: Among a study population of 1101 women and 720 men (mean age 69) there were 462 subjects (25%) who reported a diagnosis of OA. In both sexes, subjects with OA had higher bone density (adjusted for age and body mass index) at both the femoral neck (men, p = 0.026; women, p = 0.048) and lumbar spine (men, p = 0.0007; women, p = 0.0007). However, in both sexes, those with self-reported OA also had higher body sway and lower quadriceps strength. The combination of these observed differences in fracture risk factors led to no predicted change in fracture risk overall when using established nomograms for this population [men, OR = 1.11 (95% CI 0.83-1.45); women, OR = 1.08 (95% CI 0.83-1.39)]. This paralleled our observational finding that self-reported OA was not associated with a decrease in fracture incidence compared to those not reporting OA in both men (RR 0.64, 95% CI 0.29-1.39) and women (RR 1.00, 95% CI 0.66-1.51). CONCLUSION: Individuals with self-reported OA, despite higher bone density, are not protected against nonvertebral osteoporotic fracture, apparently due to worsened postural s...

Abstract
Because of the clinical and experimental utility of continuous finger blood pressure measurements and the need for accuracy, we tested the performance of a new hydraulic device in 22 consecutive hypertensive subjects during physiological and pharmacological interventions. Ipsilateral brachial intra-arterial pressure was monitored during rest, Valsalva’s maneuver, static handgrip, and mental arithmetic and after sublingual glyceryl trinitrate. In excess of 40 000 blood pressure values were analyzed. Average bias (intra-arterial minus finger blood pressure) was 8.2±17.0 mm Hg (mean±SD,
P
=NS) for systolic and 2.8±10.4 mm Hg (
P
=NS) for diastolic pressure. Two-way ANOVA of biases with subject and task factors showed a subject effect (
P
<.001). Intersubject and intrasubject standard deviations of bias were 13.8 and 9.8 mm Hg systolic and 8.7 and 5.7 diastolic, respectively. Linear drift (millimeters of mercury per minute) of finger pressure was greater (
P
<.001) for systolic than diastolic pressure during static exercise and math and after glyceryl trinitrate. Coefficients of determination for blood pressure ranged from 0.4±0.3 to 0.8±0.3 during the tasks. We conclude that (1) noninvasive finger blood pressure faithfully follows intra-arterial changes but with clinically relevant offsets, (2) this technique is best suited for assessing pressure changes, (3) physiological and pharmacological interventions do not consistently affect finger pressure accuracy, (4) many reports of finger blood pressure measuring devices are based on direct readings obtained with inadequate system response characteristics, and (5) the tested instrument falls short of the standards requirements (bias ≤5±8 mm Hg) f...

This paper addresses the structure and an associated on-line learning algorithm of a feedforward multilayer connectionist network for realizing the basic elements and functions of a traditional fuzzy logic controller. The proposed Fuzzy Adaptive Learning Control Network (FALCON) can be contrasted with the traditional fuzzy logic control systems in their network structure and learning ability. An on-line structure/parameter learning algorithm, called FALCON-ART, is proposed for constructing the FALCON dynamically. The FALCON-ART can partition the input/output space in a flexible way based on the distribution of the training data. Hence it can avoid the problem of combinatorial growing of partitioned grids in some complex systems. It combines the backpropagation learning scheme for parameter learning and the fuzzy ART algorithm for structure learning. More notably, the FALCONART can on-line partition the input/output spaces, tune membership functions, and find proper fuzzy logic rules dynamically without any a priori knowledge or even any initial information on these. The proposed learning scheme has been successfully used to control two unstable nonlinear systems. They are the seesaw system and the inverted wedge system.

The potassium supplying capacity of soils formed on three geological deposits along an east-west transect in the Niger Delta region of Nigeria was investigated by determining the various forms of soil K and K uptake by repeated maize croppings in pots. Soils (Inceptisols and Entisols) formed on recent alluvial materials of the Meander Belt deposits (MBD) had mica and feldspars resulting in very high levels of total K (4.4 and 5.1%) and nonexchangeable K (NEK) extracted by concentrated H2SO4 and boiling HNO3 (H2SO4K: 378 and 477 μg g-1; HNO3z.sbnd;K: 158 and 174 μg g-1. Soils formed on the other two geological deposits (Sombreiro-Warri deposits, SWD, and Coastal Plain Sands, CPS) had low levels of total K (CPS, 0.18-0.37% and SWD, 0.28-1.76%) and NEK H2SO4K and HNO3K for CPS were 40-87 and 18-49 μg gt1̄ respectively and for SWD they were 40-158 and 14-80 μg g-1 respectively) indicative of the highly weathered nature of these soils (Ultisols) with traces of K-containing minerals. The trend in soil K levels in the three deposits are opposite of the previously reported soil P trend. Potassium uptake by maize induced release of NEK to the plant-available K pool. Potassium supply to plants from the NEK pool for 3 successive maize crops in MBD, SWD and CPS soils were 303-435, 32-57 and 21-38 μg K g-1 soil, respectively. NEK uptake, as a percentage of total K uptake, decreased with successive croppings in CPS soils and reached zero at the third cropping, while in MBD soils the percentage remained constant up to the third and last crop. In this respect, some SWD soils behaved similar to MBD soils and others to CPS soils. © 1995.

Cadmium (Cd) accumulating in the kidneys of older grazing animals threatens the continued access of New Zealand offal products to traditional markets. Phosphatic fertilizers represent the largest input of Cd into pastoral farming systems. Little research has been conducted on the cycling of Cd in grazed pastures. To estimate the distribution of Cd in grazed pastures, soil samples were collected from self-contained farmlets which had received either high superphosphate (HF) inputs (765 kg P ha-1), low superphosphate (LF) inputs (113 kg P ha-1) or no phosphate fertilizer (UF) inputs over the previous 20 years. The average total Cd concentration in the surface soil (0-30 mm; bulk density 0 • 64 g cm-3) of the farmlets which had received HF inputs was 0-40 mg kg-1 soil (range 0-18-0-60 mg kg-1), whereas farmlets which had received LF or no fertilizer inputs had an average Cd concentration of 0 • 10 mg kg-1 (range 0 • 02-0 • 19 mg kg-1). Cadmium concentration decreased with soil depth. The concentration of Cd in mixed herbage reflected the difference in soil Cd between the HF (meamtstandard error = 0-321±0-033 mg Cd kg-1 dry matter) and LF (0 • 063±0 • 004 mg Cd kg-1 dry matter) farmlets. Soil Cd accumulation was highest on low slopes (0-12°) and lowest on high slopes (>26°) in both LF and HF farmlets, whereas pasture Cd concentration in the HF farmlet increased with slope from 0 ■ 178±0 • 035 mg Cd kg-1 on low slopes to 0-487±0-053 mg Cd ha-1 on high slopes. A strong relationship was obtained between soil Cd and P in the 0-30 mm layer of the HF farmlet, demonstrating the link between phosphate fertilizer use and Cd accumulation. Zinc to Cd ratios were much lower in this layer compared with those in LF and UF sites, providing further evidence of the contribution of phosphate fertilizer to soil Cd.A model originally developed to explain the distribution of soil P in sheep-grazed fertilized hill pastures gave good predictions of present day soil Cd distribution in the H...

We employed the polymerase chain reaction and genomic DNA library screening to clone novel human genes, GPR9 and GPR10, and a rat gene, GPR14. GPR9, GPR10, and GPR14 each encode G protein-coupled receptors. GPR10 and GPR14 are intronless within their coding regions, while GPR9 contains at least one intron. The receptor encoded by GPR9 shares the highest identity with human IL-8 receptor type B (38% overall and 53% in the transmembrane regions), followed by IL-8 receptor type A (36% overall and 51% in the transmembrane domains). GPR10 encodes a receptor that shares highest identity with the neuropeptide Y receptor (31% overall and 46% in the transmembrane domains). The receptor encoded by GPR14 shares highest identity with the somatostatin receptor SSTR 4 (27% overall and 41% in the transmembrane domains). Fluorescencein situhybridization analysis localized GPR9 to chromosome 8p11.2-p12 and GPR10 to chromosome 10q25.3-q26. © 1995 by Academic Press, Inc.

In this paper, the dynamics of quadruped trot, gallop, and bound will be examined using a simple model for the quadruped. The body of the quadruped is modeled as a uniform bar and the legs are modeled by massless springs. It will be shown that symmetry can be used to study the locomotion of this system. Using symmetry, a technique will be developed to obtain periodic solutions for each of the gaits of the quadruped model. These periodic solutions will be computed at various speeds. The energy levels will be compared for each of the gaits. The exchange of energy between its different forms will be shown for different gaits. It will be shown that even without body flexibility, there are significant savings in energy due to gait transition from trot to gallop. The energy levels will be used to predict the trot-gallop transition speed. These results will be compared with the experimental results for horses and dogs.

Extracellular ATP and ADP mediate diverse physiological responses in mammalian cells, in part through the activation of G protein-coupled P2 purinoceptors. The cloning and expression of cDNAs encoding several P2 purinoceptor subtypes have enabled rapid advances in our understanding of the structural and functional properties of these receptors. The current report describes the isolation of a gene from a human genomic library that encodes a protein with the greatest similarity to the human P(2U) purinoceptor, a subtype that is distinguished by its ability to be activated by uridine nucleotides as well as adenine nucleotides. When expressed in a mammalian cell line, this novel receptor is activated specifically by UTP and UDP but not by ATP and ADP. Activation of this uridine nucleotide receptor resulted in increased inositol phosphate formation and calcium mobilization. Fluorescence in situ hybridization revealed that the gene encoding the uridine nucleotide receptor is located in region q13 of the X chromosome. Dendrogram analysis of the G protein-coupled P2 purinoceptors and the uridine nucleotide receptor indicates that these receptors belong to a family that may be more aptly named nucleotide receptors.

The risk of osteoporotic fracture is related to peak bone mass achieved at skeletal maturity and subsequent bone loss. Although premature menopause is a risk factor for osteoporosis, the effect of exposure to endogenous estrogen during a woman’s reproductive years is poorly characterized. We analyzed the relationship between reproductive factors and estrogen exposure on bone mineral density (BMD) and incidence of atraumatic fracture in data from 1091 women (age: 70 ± 7.2 yr; mean ± SD) participating in the Dubbo Osteoporosis Epidemiology Study. Age- and weight-adjusted BMD among women who had used estrogen replacement therapy (ERT) for more than 5 yr was higher at the lumbar spine and femoral neck by 13.7% and 10.2% (P < 0.001), respectively, compared with women who had used ERT for less than 5 yr or nonusers. Duration of exposure to estrogen (years of menstruation plus postmenopausal ERT use) was associated with higher BMD, such that BMD increased by 2-3% for every 10-yr increase in years of estrogen exposure; thus women who menstruated for more than 40 yr had a 6-8% higher BMD than did women who menstruated for less than 30 yr. Higher BMD was also significantly associated with high parity, such that nulliparous women had 5-6% lower BMD than did their peers of the same age and weight. The incidence of atraumatic fractures among non-ERT users was higher than that of ERT-users [odds ratio (OR): 1.06; 95% confidence interval (CI): 0.94-1.16] and was significantly lower among parous women than among nulliparous women (OR 0.94; 95% CI: 0.84-0.98) in univariate analysis. Longer duration of menstruation was associated with lower fracture incidence (OR for 1 SD = 6.6 yr: 0.93; 95% CI: 0.86-1.02). Moreover, when all of these factors were considered simultaneously, parity remained a significant determinant of fracture as well as femoral neck BMD. We conclude that high parity and longer duration of exposure to estrogen, either through natural menstruation or postmenopausal...

Following the cloning of the opioid receptors μ, κ, and δ, we conducted a search for related receptors. Using oligonucleotides based on the opioid and also the structurally related somatostatin receptors, we amplified genomic DNA using the polymerase chain reaction and isolated fragments of novel G protein-coupled receptor genes. Two of these gene fragments designated clones 12 and 11 were used to isolate the full-length genes. The intronless coding sequences of these genes, named GPR7 and GPR8, shared 70% identity with each other, and each shared significant similarity with the sequences encoding transmembrane regions of the opioid and somatostatin receptors. GPR7 was mapped to chromosome 10q11.2-q21.1 and GPR8 chromosome 20q13.3. Northern blot analysis using human mRNA demonstrated expression of GPR7 mainly in cerebellum and frontal cortex, while GPR8 was located mainly in the frontal cortex. In situ hybridization revealed expression of GPR7 in the human pituitary. A partial sequence of the mouse orthologue of GPR7 was obtained, and in situ hybridization demonstrated expression in discrete nuclei of brain, namely suprachiasmatic, arcuate, and ventromedial nuclei of hypothalamus. A stable cell line expressing the GPR7 gene was created, but expression levels of the receptor were low. The available pharmacology indicated binding to several opioid drugs such as bremazocine, levorphanol, and β-FNA, but not to the opioid receptor subtype-selective μ, δ, or κ agonists. © 1995 Academic Press, Inc.

View description>>
A frost heave model which simulates formation of ice lenses is developed for saturated salt-free soils. Quasi-steady state heat and mass flow is considered. Special attention is paid to the transmitted zone, i.e. the frozen fringe. The permeability of the frozen fringe is assumed to vary exponentially as a function of temperature. The rates of water flow in the frozen fringe and in the unfrozen soil are assumed to be constant in space but vary with time. The pore water pressure in the frozen fringe is integrated from the Darcy law. The ice pressure in the frozen fringe is determined by the generalized Clapeyron equation. A new ice lens is assumed to form in the frozen fringe when and where the effective stress approaches zero. The neutral stress is determined as a simple function of the unfrozen water content and porosity. The model is implemented on an personal computer. The simulated heave amounts and heaving rates are compared with experimental data, which shows that the model generally gives reasonable estimation.

An operational model for estimation of frost heave in field where stratified soil profile appears is presented. The model is developed from the research model described in part B. Soil layers are first classified into frost-susceptible layers (FSL) or non-frost-susceptible layers (NFSL). In an FSL, both heat flow and water flow are considered and ice lensing can occur. In a NFSL, only heat flow is possible and no ice lensing is allowed. The governing equations for heat and mass transfer are established for the time period when the frost front is moving within FSL. Capillarity and unsaturation are also considered. The operational model is verified by field measurements of heave amounts. Examples of application are given.

The pulse-receiving performance of the antenna was evaluated using a time-domain antenna range. The antenna was also tested in a TEM cell both in time and frequency domains. The antenna is capable of receiving a 520-ps approximately Gaussian pulse, incident within 45° from the boresite direction, with good fidelity. The frequency-domain receiving transfer function (or the effective height) of the antenna is within - 57±3 dB metres in the 22 MHz-1.1 GHz frequency range.

The performance of direct sequence spread spectrum (DSSS) ISM band Radio Local Area Networks (RLANs) using BPSK modulation and matched filter receivers is investigated. Short and long pseudonoise (PN) spreading sequences, a Barker code and an M- sequence, have been employed in both differential and coherent systems operating in a Rayleigh fading multipath channel with different delay spreads. A channel estimator was designed to perform the system synchronization and control the receiver in order to mitigate the multipath fading and time-dispersion effects by using various multipath diversity techniques. It is found that with low delay spreads the short sequence leads to much better system performance than the long one. It is also shown that use of coherent instead of differential techniques increases the maximum tolerable delay spread.

The HIPERLAN system will operate in the 5 GHz and the 17 GHz bands at a data rate of >23.5 Msymbols. Access to the radio medium is assumed to be asynchronous and the medium to be a Rayleigh fading channel. These would need a robust, synchronization mechanism, so that both timing instants in the receiver can be chosen and equalization performed to mitigate the effects of the time dispersive channel. Results show that the codes perform well under moderately severe channel conditions. An optimum 16 bit sequence was selected for appending to the start of frame synchronization sequence to make up for the full 48 bit training sequence. The added sequence preserves the desired correlation function properties of low sidelobes and zero imaginary part.

Fuzzy reasoning processors have been employed in many commercial and industrial applications. A high-performance pipelined, single-instruction-stream, and single-data-stream architecture of fuzzy reasoning engine has been designed. Based on this architecture, the proposed VLSI processor for embedded real-time fuzzy logic applications was fabricated in a 0.8-mm CMOS technology. Its computation power can reach 2.5 Million Fuzzy Logic Inferences Per Second (MFLIPS) at a system clock of 20 MHz. In order to efficiently realize fuzzy applications, a software development system under Microsoft Windows has also been designed. For the purpose of showing its effectiveness, we have carried out the experiments to successfully control the crane system. Experimental results have shown the efficient cooperative control of the proposed fuzzy reasoning processor with software development system and can be contrast with conventional computer software interface control.

Compression of digital video is the only viable means to transport real-time full-motion video over BISDN/ATM networks. Traffic streams generated by video compressors exhibit complicated patterns which vary from one compression scheme to another. In this paper we investigate the trafficcharacteristics of video streams which are compressed based on the MPEG standard. Our study is based on 23 minutes of video obtained from an entertainment movie. A particular significance of our data is that it contains all types of coded frames, namely: Intra-coded (I), Prediction (P), and Bidirectional (B) MPEG frames. We describe the statistical behavior of the VBR stream using histograms and autocorrelation functions. A procedure is developed to determine the instants of a scene change based on the changes in the size of successive/frames. It is found that the length of a scene can be modeled by a geometric distribution. A model for an MPEG traffic source is developed in which frames are generated according to the compression pattern of the captured video stream. For each frame type, the number of cells per frame is fitted by a lognormal distribution whose parameters are determined by the frame type. The appropriateness and limitations of the model are examined by studying the multiplexing performance of MPEG streams. Simulations of an ATM multiplexer are conducted, in which traffic sources are derived from the measured VBR trace as well as the proposed model. The queueing performance in both cases is found to be relatively close.

The good about Multimedia Conferencing (MMC) is that everybody likes to use it. The bad is that almost no standards or recommendations for MMC exist, and the ugly is that this situation prohibits the wide-spread availability of Multimedia Conferencing services. This article discusses problems and proposes solutions with respect to standardising MMC services. Some of the problems of existing MMC services is that most of them do not operate in a distributed multi-vendor heterogeneous environment. To operate in such an environment, as proposed by the TINA project, generic MMC interfaces should be specified. As a starting point for standardization specifications of the MMC operational interface, the Stream interface and the Management interface are given. The interfaces are specified from an information and computational viewpoint as defined by RM-ODP, using techniques like OMT and OMG IDL.

It is expected that these bodies have a major impact in the area of distributed processing. However, concepts and mechanisms to support real-time communication are not yet fully included or detailed in these standards. In particular this paper addresses Quality of Service (QoS) specifications for continuous dataflows. These QoS specifications are described from the ODP computational and engineering viewpoint and the repercussions of these QoS specifications for functions located in both the computing and telecommunications environment are discussed.

We propose a three-class taxonomy of error functions, based on the limit behaviour of the error signal. We classify four established error functions: the quadratic, Fahlman's Quickprop, entropy, and the exception error function. We introduce two new error functions, and benchmark all six on the N-2-N encoder. The two new functions found correct solutions faster and more reliably than the established functions.

We describe an empirical comparison of the scaling behaviour of six error functions, on a conjugate gradient form of Back Propagation. We classify the functions according to the limit behaviours of their respective error signals, as the target value and the actual output value approach opposite extremes. These limit behaviours are zero limit, finite limit, and infinite limit. Despite such a wide divergence in their limit behaviours, we find that all six error functions exhibit a median run-time order of approximately O(N 4) on the N-2-N encoder. This result indicates that, while some factors affecting the scaling behaviour of standard and conjugate gradient Back Propagation have been previously identified (such as saturation), other factors remain unidentified.

A state dependent cost of accepting a call is introduced to measure the benefit of alternate routes. This cost function, which requires expensive calculations, can be approximated to a linear form without much error. Based on this cost approximation, a dynamic trunk reservation level is derived. It is easy to implement on-line and gives a better overload performance than a fixed trunk reservation level. Simulation studies confirm our results.

© 1995 IEEE. All rights reserved. This paper presents a model for a wide-band fading channel for terrestrial mobile applications. The model is based on the results of measurements made in a heavily built-up urban environment of a 25 MHz signal centred at approximately 2.6 GHz. This paper presents the measured impulse response and details the parameter extraction process used to determine the characteristics of the channel. These parameters are used in the channel simulation package and the output of this simulation are compared to the original data.
