Land mobile satellite channel measurements and modeling

This paper, tutorial in nature, describes the effort of many investigators who have and still are conducting channel measurements and modeling for land mobile satellite communications. Various channel measurement results, ranging from ultrahigh frequency to Ka-band, are given. Many statistical channel models and simplified models that have been developed are referred to. Some of the models are applicable to geostationary and nongeostationary communications satellites. A statistical model developed by Loo (1985) is described in detail, as well as its extension to modeling land mobile satellite communications at Ka-band. This was accomplished by including a Gaussian probability density function to account for weather conditions. Also, practical computer-generated statistical channel models are given. These computer models should facilitate the estimation of performance of satellite communications systems.
Modular backstepping design of an estimation-based sliding mode controller for uncertain nonlinear plants

A partially recursive backstepping-like procedure to design estimation-based controllers for uncertain nonlinear systems is presented. Its motivation relies on the intent of reducing the computational load of the n-steps backstepping design by exploiting the promising features of second order sliding mode control. The proposed approach exhibits modularity, in the sense that the controller is proved to guarantee input-to-state stability regardless of the choice of the parameter estimation mechanism.
A 12 bit 1.6 GS/s BiCMOS 2×2 hierarchical time-interleaved pipeline ADC

A 12 bit 1.6 GS/s pipeline ADC realized in a 0.18 μm complementary BiCMOS SiGe process is presented. The ADC consists of a four-way time-interleaved hierarchical structure and a master-slave T/H to improve the dynamic performance of the individual sub-ADCs and to reduce both the complexity of the required interleaving background calibration algorithms and the error rate. It achieves an SFDR of 79 dBc at low frequency inputs and 66 dBc at Nyquist, and has an error rate of less than 10-9.

Suboptimal cycle bases of graphs using ant colony system algorithm

Purpose – Cycle bases of graphs have many applications in science and engineering. For an efficient force method of structural analysis, a special cycle basis corresponding to sparse cycle adjacency matrix is required. The purpose of this paper is to develop an ant colony system (ACS) algorithm for the generation of a cycle basis, leading to suboptimal cycle bases.Design/methodology/approach – In this paper, an ACS algorithm is developed for the generation of a cycle basis, leading to suboptimal cycle basis corresponding to highly sparse flexibility matrices. Examples are included to illustrate the efficiency of the developed algorithm.Findings – A new approach is developed which uses the recently developed ACS algorithm for the optimization.Originality/value – Previously, graph theoretical method had been used for the formation of suboptimal cycle bases. Here, optimization is performed using ACS algorithm for the first time.
Saliency map model based on the edge images of natural scenes

In this paper, we propose a new saliency map model to find a saliency point based on an edge image rather than a complex natural scene. We use independent component analysis to find a filter that can generate a saliency point from edge information with a gray scale. Computer experimental results show that the proposed saliency map model successfully generates the saliency points, of which the results are very considerable.
The impact and adoption of GLUE 2.0 in the LCG/EGEE production Grid

The GLUE information schema has been in use in the LCG/EGEE production Grid since the first version was defined in 2002. In 2007 a major redesign of GLUE, version 2.0, was started in the context of the Open Grid Forum following the creation of the GLUE Working Group. This process has taken input from a number of Grid projects, but as a major user of the version 1 schema LCG/EGEE has had a strong interest that the new schema should support its needs. In this paper we discuss the structure of the new schema in the light of the LCG/EGEE requirements and explain how they are met, and where improvements have been achieved compared with the version 1 schema. In particular we consider some difficulties encountered in recent extensions of the use of the version 1 schema to aid resource accounting in LCG, to enable the use of the SRM version 2 storage protocol by the LHC experiments, and to publish information about a wider range of services to improve service discovery. We describe how these can be better met by the new schema, and we also discuss the way in which the transition to the new schema is being managed.
Syntax outranks phonology: evidence from Ancient Greek

What influence do syntax and phonology have on one another ? Two types of answer to this question appear in the literature. The consensus view is probably best expressed by Zwicky & Pullum (1986) (see also Myers 1987; Vogel & Kenesei 1990), who claim that the relation is one-way: although phonological phrasing above the word is affected by syntactic structure, syntax itself is phonology-free.
Approaching real-time processing for matching pursuit image coding

One approach to transformation based compression is the Matching Pursuit Projection (MPP). MPP or variants of it have been suggested for designing image compression and video compression algorithms and have been among the top performing submissions within the MPEG-4 standardization process. In the case of still image coding, the MPP approach has to be paid with an enormous computational complexity. In this work we discuss sequential, as well as parallel speedup techniques of a MPP image coder which is competitive in terms of rate-distortion performance.

Strengthening accountability to citizens on gender and health.

Abstract Accountability refers to the processes by which those with power in the health sector engage with, and are answerable to, those who make demands on it, and enforce disciplinary action on those in the health sector who do not perform effectively. This paper reviews the practice of accountability to citizens on gender and health, assesses gaps, and recommends strategies. Four kinds of accountability mechanisms have been used by citizens to press for accountability on gender and health. These include international human rights instruments, legislation, governance structures, and other tools, some of which are relevant to all public sector services, some to the health sector alone, some to gender issues alone, and some to gender-specific health concerns of women. However, there are few instances wherein private health sector and donors have been held accountable. Rarely have accountability processes reduced gender inequalities in health, or addressed ‘low priority’ gender-specific health needs of wom.
Modelling the effects of multi-modal travler information systems

: This paper proposes a multi-class probit-based stochastic user equilibrium model for assessing the effects of multi-modal traveler information systems (MTIS) on a multi-modal transport network. It can be formulated as a fixed-point problem and solved by a simulation-based heuristic solution algorithm. It is assumed in this paper that the travelers equipped and unequipped with MTIS would make their travel choices following a probit-based stochastic manner when considering alternative paths or modes according to their perceived utilities. The proposed model and solution algorithm can be used to evaluate explicitly the impacts of MTIS services. Numerical results show that the introduction of MTIS would improve the network performance and promote the utilization of public transit under certain market penetration and congestion levels
Erythropoiesis after Therapy with Recombinant Human Erythropoietin: A Dose–Response Study in Anemic Cancer Surgery Patients

Background and Objectives: Preoperative treatment with 600 U/kg of recombinant human erythropoietin (r–HuEPO) effectively increases erythropoiesis in cancer patients. The aim of this study was to evaluate the erythropoietic response after different doses of r–HuEPO in order to find the minimum effective dose. Materials and Methods: Twenty anemic sideropenic patients (hemoglobin ≤110 g/l; serum iron <600 μg/l) with cancer of the gastrointestinal tract were randomly allocated to two groups: the first (n = 10) received 400 U/kg of r–Hu EPO divided in 4 doses (100 U/kg each, every 4 days); the second (n = 10) received 200 U/kg of r–HuEPO (50 U/kg each, every 4 days). Both groups were given intravenous iron gluconate (125 mg) every day for 15 days. Results: After treatment, the serum iron level significantly rose in both groups. The production of new red blood cells was 176.3±90.8 ml in the 200 U/kg group and 268.4±79.4 ml in the 400 U/kg group (p = 0.036). The increase of hemoglobin was significantly higher in the 400 U/kg group (22.3±2.0 g/l) than in the 200 U/kg group (14.1±2.7 g/l) (p = 0.017). Conclusion: The r–HuEPO dose of 400 U/kg appears significantly more effective than the 200 U/kg to stimulate erythropoiesis in anemic sideropenic cancer patients.
Fast Approach to Video Stabilization Based on Hierarchical Estimation of Global Motion with Parallel Computation

In this article, a fast approach of video stabilization is presented based on haerachical estimmation of global motion and multi-thread parallel computation. At first, the structure-texture decomposition is adopted to tackle the negative effect from illumination changes. Then according to pyramid structure of image texture a hierachical model is built to estimate global motion parameters with least square method. Afterwards Gaussian smoothing method is employed to eliminate error accumulation in motion compensation. Meanwhile the multi-thread parallel computation is used to speed up the processing efficiency so as to achieve a real time performance for videos with 25fps.
Comments on “Referential CPs and DPs: An operator movement account”

This paper attempts a novel and impressive assimilation of embedded clauses which predicts the distribution of Main Clause Phenomena in these clauses. Simplifying somewhat, the proposal is that a certain class of Main Clause Phenomena, namely argument fronting, are blocked by covert operator movement. Some embedded clauses have operator movement and these block argument fronting; others don’t and these allow argument fronting. Three environments are examined in this paper where argument fronting, a representative Main Clause Phenomenon, is blocked: temporal clauses, conditional clauses, and factive clauses. If these environments can be demonstrated to have the relevant kind of operator movement, then the paper will have succeeded in its goals. In this discussion, I will consider the first two cases only briefly. The first case considered is that of temporal clauses and here there is clear evidence for operator movement from the existence of high/low construals and presence of island effects.

Trauma analysis in paleopathology

This paper reviews the mechanisms of injury and the types of fractures that most commonly affect the human skeleton, presents descriptive protocols for cranial and postcranial fractures adapted from clinical and forensic medicine, and summarizes anatomically the injuries most likely to be found in archaeological skeletons along with their most common causes and complications. Mechanisms of injury are categorized as direct and indirect trauma, stress, and fracture that occurs secondary to pathology. These are considered to be the proximate, or most direct, causes of injury and they are influenced by intrinsic biological factors such as age and sex, and extrinsic environmental factors, both physical and sociocultural, that may be thought of as the ultimate, or remote, causes of injury. Interpersonal conflict may be one of those causes but the skeletal evidence itself is rarely conclusive and must therefore be evaluated in its individual, populational, sociocultural, and physical context. A cautionary tale regarding parry fractures is presented as an illustration. Yrbk Phys Anthropol 40:139–170, 1997. © 1997 Wiley-Liss, Inc.
Automatic Parameter Estimation From Well Test Data Using Artificial Neural Network

We propose a robust way of achieving a well test interpretation by combining the sequential predictive probability method with an artificial neural network approach. The sequential predictive probability method considers all possible reservoir models and determines which candidate model or models best predict the well response. This method is dependent on obtaining good initial estimates for the parameters governing the candidate reservoir models, which is achieved by applying the artificial neural network approach. We use the neural network to identify the characteristic components of the pressure derivative curve corresponding to the flow regimes known to be in each candidate model. Reservoir parameters are then computed using the data in the identified range of the corresponding behavior. As a final step, the candidate models and their initial estimates are evaluated using the sequential probability method. The method discriminates between the candidate models and simultaneously performs nonlinear regression to compute the best estimates of reservoir parameters. The trained neural network was able to identify the characteristic components of the derivative curve in most cases. The algorithm written to interpret the neural network signals into flow regimes required special procedures to take care of the misclassification from the neural network. The initial estimatesmore » of reservoir parameters from the neural network were found to be reasonably close to the eventual estimates from the sequential predictive probability method. « less
EXTRAPOSITION AND VP-SHELL

This paper concerns some syntactic constraints imposed on Extraposition from NP. It has been pointed out in the literature that Extraposition is possible from D-structure object NPs. The present study examines applicabilities of Extraposition to object NPs in double complement constructions, and shows that while the second complement NPs tolerate Extraposition, the first ones reject Extraposition. I claim that this constraint imposed on the first complement NPs follows immediately from the Larsonian shell analysis of phrase structures. This in turn means that the present study motivates the shell analysis of phrase structures in terms of extraction phenomena. *

Task allocation for wide area search munitions

Addresses the problem of task allocation for wide area search munitions. The munitions are required to search for, classify, attack, and perform battle damage assessment on potential targets. It is assumed that target field information is communicated between all elements of the swarm. A network flow optimization model is used to develop a linear program for optimal resource allocation. Periodically re-solving this optimization problem results in coordinated action by the search munitions. The network optimization model can be initialized such that multiple vehicles can be assigned to service a single target. Memory of previous task assignments is included in the task benefit calculations to reduce churning due to frequent reassignments. Simulation results are presented for a swarm of eight vehicles searching an area containing three potential targets. All targets are quickly classified, attacked, and verified as destroyed.
Constructing Model of Relationship among Behaviors and Injuries to Products Based on Large Scale Text Data on Injuries

In Japan, childhood injury prevention is urgent issue. Safety measures through creating knowledge of injury data are essential for preventing childhood injuries. Especially the injury prevention approach by product modification is very important. The risk assessment is one of the most fundamental methods to design safety products. The conventional risk assessment has been carried out subjectively because product makers have poor data on injuries. This paper deals with evidence-based risk assessment, in which artificial intelligence technologies are strongly needed. This paper describes a new method of foreseeing usage of products, which is the first step of the evidence-based risk assessment, and presents a retrieval system of injury data. The system enables a product designer to foresee how children use a product and which types of injuries occur due to the product in daily environment. The developed system consists of large scale injury data, text mining technology and probabilistic modeling technology. Large scale text data on childhood injuries was collected from medical institutions by an injury surveillance system. Types of behaviors to a product were derived from the injury text data using text mining technology. The relationship among products, types of behaviors, types of injuries and characteristics of children was modeled by Bayesian Network. The fundamental functions of the developed system and examples of new findings obtained by the system are reported in this paper.
Performance Issues and Error Analysis in an Open-Domain Question Answering System

This paper presents an in-depth analysis of a state-of-the-art Question Answering system. Several scenarios are examined: (1) the performance of each module in a serial baseline system, (2) the impact of feedbacks and the insertion of a logic prover, and (3) the impact of various retrieval strategies and lexical resources. The main conclusion is that the overall performance depends on the depth of natural language processing resources and the tools used for answer finding.
The Myth of the Sophisticated User

Abstract Users now know just enough to be dangerous. How many times have you heard that one? How many times have you said it yourself? After a few years of watching users “take over,” some MIS professionals view users as more of a nuisance than in the days before end-user computing. But is this attitude justified, or is it simply the view of MIS professionals disgruntled by the growing computer expertise of those who haven't paid their dues?
Radio propagation at microwave frequencies for line-of-sight microcellular mobile and personal communications

A propagation experiment has been designed and conducted at 900 MHz and 11 GHz to characterize microcell channels using various antennas at two distinct frequencies. It is found that propagation in rural areas is dominated by interference between the direct, line-of-sight ray and a specular roadway-reflected ray. In urban areas, the addition of four specular wall-reflected rays adequately represents microcell propagation. The dependence of mean power falloff, measured mean power and calculated power on distance was determined. The lambda /2 scale microvariations of the received power are reduced compared to the variations in present cellular radio systems. For urban sites using omnidirectional base and mobile antennas, the RMS delay spread due to road- and wall-reflected rays was obtained from a six-ray model. Using a 20-dB horn for the mobile antenna can reduce this delay spread. >
Performing Drug Safety Research During Pregnancy and Lactation: Biomedical HIV Prevention Research as a Template

Abstract Evidence-based guidance regarding use of nearly all pharmaceuticals by pregnant and lactating women is limited. Models for performing research may assist in filling these knowledge gaps. Internationally, reproductive age women are at high risk of human immunodeficiency virus (HIV) acquisition. Susceptibility to HIV infection may be increased during pregnancy, and risk of maternal-child transmission is increased with incident HIV infection during pregnancy and lactation. A multidisciplinary meeting of experts was convened at the United States National Institutes of Health to consider paradigms for drug research in pregnancy and lactation applicable to HIV prevention. This report summarizes the meeting proceedings and describes a framework for research on candidate HIV prevention agent use during pregnancy and lactation that may also have broader applications to other pharmaceutical products.
