The multiple-call hand-off problem in high-capacity cellular communications systems

A preliminary analytical model that characterizes the central issues of the hand-off problem when vehicles can support multiple calls simultaneously is described. In such cases a cell-boundary crossing by a single vehicle can generate multiple hand-off attempts. Theoretical performance characteristics that show blocking and hand-off failure probabilities as functions of communications traffic are determined. The results indicate that cut-off priority can be effective in reducing forced termination due to hand-off failure in an environment where platforms support multiple calls. <<ETX>>
Optical fiber based sensor for angular measurement in rehabilitation

A specific articular exercise may be needed under particular circumstances in rehabilitation. In such cases, it is very important to quantify the angular kinematics of movements which are imposed to the patient in order to attain firstly, a possible well-adapted rehabilitation and secondly, a clinical follow-up. This research is originated from the lack of user-friendly, versatile and inexpensive apparatus which are commercially available. A study has been undertaken on the realization of versatile sensors, specifically for angular measurement using optical fiber. Its originality relies on applications of different scientific concepts. Following a significant bibliographic research, a geometric approach has been adopted in analyzing the power fading along the fiber due to its curvature. For the study of the light wave's behaviour as a function of curvature and optical fiber angle, an automatic testing bench is constructed. Thus the sensed signal which is electronically processed represents an indirect measure of curvature angle. Finally, overall performances of the developed sensor are discussed with the experimental results. <<ETX>>
Networked simulators: effects on the perceptual validity of traffic in driving simulators [Genetwerkte simulatoren: effecten op de perceptuele kwaliteit van verkeer in rijsimulatoren]

Simulators have been used as a tool for training for many decades, and they are still gaining importance. Originally built for stand-alone use, the emergence of (global) network communication allowed these simulators to be connected with other simulators. This introduced the possibility of practicing large, complex exercises with multiple participants. Networked simulation started with SIMNET (Miller & Thorpe, 1995), the first interconnection test bed, and the Distributed Interactive Simulation protocol (DIS), the first generally accepted protocol for data communication between simulators. To minimize the effects of network communication (limited bandwidth, delay), the DIS protocol allows the use of dead reckoning. Using dead reckoning, network load and the effects of delay can be reduced.
Comparative Victim and Offender Research: Cross-National and Cross-Cultural Theoretical Approaches and Methodologies

Cross-national research is valuable, even indispensible, for establishing the generality of findings and the validity of interpretation derived from singlenation studies. In no other way can we be certain that what we believe to be social-structural regularities are not merely particularities, the product of some limited set of historical and cultural or political circumstances. Crossnational research is equally valuable, perhaps even more valuable, for forcing us to revise our interpretations to take account of cross-national differences and inconsistencies that could never be uncovered in single-nation research.

Cross-Modal Learning Filters for RGB-Neuromorphic Wormhole Learning

(cid:151)Robots that need to act in an uncertain, populated, and varied world need heterogeneous sensors to be able to perceive and act robustly. For example, self-driving cars currently on the road are equipped with dozens of sensors of several types (lidar, radar, sonar, cameras, . . . ). All of this existing and emerging complexity opens up many interesting questions regarding how to deal with multi-modal perception and learning. The recently developed technique of (cid:147)wormhole learning(cid:148) shows that even temporary access to a different sensor with complementary invariance characteristics can be used to enlarge the operating domain of an existing object detector without the use of additional training data. For example, an RGB object detector trained with daytime data can be updated to function at night time by using a (cid:147)wormhole(cid:148) jump through a different modality that is more illumination invariant, such as an IR camera. It turns out that having an additional sensor improves performance, even if you subsequently lose it. In this work we extend wormhole learning to allow it to cope with sensors that are radically different, such as RGB cameras and event-based neuromorphic sensors. Their profound differences imply that we need a more careful selection of which samples to transfer, thus we design (cid:147)cross-modal learning (cid:2)lters(cid:148). We will walk in a relatively unexplored territory of multi-modal observability that is not usually considered in machine learning. We show that wormhole learning increases performance even though the intermediate neuromorphic modality is on average much worse at the task. These results suggest that multi-modal learning for perception is still an early (cid:2)eld and there might be many opportunities to improve the perception performance by accessing a rich set of heterogeneous
J ul 2 01 9 On Finite Exchangeability and Conditional Independence

We study the independence structure of finitely exchangeable distributions over random vectors and random networks. In particular, we provide necessary and sufficient conditions for an exchangeable vector so that its elements are completely independent or completely dependent. We also provide a sufficient condition for an exchangeable vector so that its elements are marginally independent. We then generalize these results and conditions for exchangeable random networks. In this case, it is demonstrated that the situation is more complex. We show that the independence structure of exchangeable random networks lies in one of six regimes represented by undirected and bidirected independence graphs in graphical model sense. In addition, under certain additional assumptions, we provide necessary and sufficient conditions for the exchangeable network distributions to be faithful to each of these graphs.
A Public Health Perspective on Gambling 1 : The Four Principles

During much of the past several decades, I have been working to advance my understanding of addictive behaviors. The more I studied addiction, the more the task of unraveling it became complex and challenging. Addiction is a vexing, repetitive and self-destructive pattern that seems resistant to even the best conceived devices intended to stimulate change. Typically, this resistance is explained by attributing the cause of addiction to the characteristics of ingested psychoactive drugs: as if the drugs caused addiction. New research shows that addiction is not a property of a drug or chemical any more than it is a property of dice. Certainly drugs can stimulate neuroadaptation (e.g., tolerance and withdrawal) and the development of dependence; but not everyone who takes a dependence producing drug develops such dependence. Similarly, some people gamble or shop excessively and, as a consequence, biologically adapt to the experience (i.e., neuroadaptation) so that when they stop shopping or gambling they feel the discomfort of withdrawal. These observations of behavioral or “process” addiction have encouraged scientists to rethink the very nature of addiction.
A NETWORK FLOW MODEL FOR THE VEHICLE ROUTING PROBLEM WITH TIME WINDOWS AND MULTIPLE ROUTES

The Vehicle Routing Problem (VRP) is a combinatorial optimization problem that has been widely studied in the literature, ever since it was formulated for the first time in (Dantzig and Ramser 1959). It can be seen as a generalization of another well know combinatorial problem, the traveling salesman problem, which can be described as a VRP with one vehicle, no depot, no vehicle capacities and no customer demands. Generally speaking, it is the problem of scheduling a fleet of vehicles to visit a set of customers, to whom they must deliver or collect a demanded quantity of goods. The problem consists of finding the best set of routes, according to a given objective function, such that all operational constraints of the vehicles are respected, and the set of customers is covered. This objective function can be the minimization of all traveling costs, the maximization of the number of served customers, or some combination of these or other factors. The VRP is well-know to be NP-hard, and so are most of its variants. Its solution methods include several heuristic and metaheuristic approaches, as well as some exact methods, mainly based on branch-and-bound techniques. The classical version of the VRP is commonly called the Capacitated Vehicle Routing Problem, as the vehicles in the fleet have limited capacities. There are several variants of this problem. In (Toth and Vigo 2002; Cordeau, J.-F et al. 2007), the authors describe the VRP and some of its main variants.
Optimal predictive TX combining diversity in correlated fading for microcellular mobile radio applications

Transmitter diversity uses several transmit antennas to improve the performance of digital transmission in a fading environment. In transmitter selection diversity the best transmit antenna is selected on the basis of estimates of the propagation conditions from each antenna to the single receive antenna. In time division duplex systems these estimates can be obtained by measuring the received signal at each antenna in the receive time slots, which precede the transmit time slot. It has been proposed to use a predictor to improve the performance for a moving receiver (predictive TX selection diversity). No analysis is available in correlated fading. We consider predictive transmitter combining diversity in contrast to selection diversity this scheme uses all transmit antennas simultaneously. Our main contribution is a derivation and an analysis of the optimal predictive TX combining diversity algorithm in correlated fading. We derive exact closed form expressions for the average probability of error for two suboptimal combining methods and tight bounds on the performance of the optimal combining method. Quantitative results on the average bit error rate and the diversity gain are given for a system with DECT parameters.

Gametogenetic cycles of three corals in Singapore

Among life functions of coral, reproduction appears to have the narrowest tolerance to stress, while being critical for maintenance of populations. However, relatively little is known about the effects of environmental stressors on reproductive output, especially in equatorial regions. In this study, the gametogenic cycles and reproductive output of three common broadcasting scleractinian corals Hydnophora exesa, Merulina ampliata and Echinopora lamellosa were investigated at three fringing reefs south of Singapore. All three species showed strong seasonality and broadly similar patterns of gametogenesis, with bi-annual peaks in fecundity occurring primarily in April, followed by a smaller secondary peak in October. Both periods coincide with the inter-monsoon, during which tidal flushing is poorest. Fecundity in all three species significantly declined from 2009 to 2011, although spatial effects were also prominent. Results indicate that oogenesis occurred over two to three months, during which fecundity metrics also elucidated negative relationships with sea surface temperature, total nitrogen and total suspended sediments and positive relationships with salinity, total organic carbon and chlorophyll-a. The directionality of relationships between fecundity, turbidity faecal coliforms were variable among species, with positive associations for H. exesa and negative associations for E. lamellosa in both cases. A bleaching event in mid-2010 had large effects on reproductive output, with reproductive failure in all three species in October 2010. This suggests these coral species are sensitive and susceptible to deteriorating water quality within the relatively short time frame of the three months associated with set Thence we have shown that, variations in fecundity are good indicators of sub-lethal coral stress, indicating that the monitoring of coral reproductive output is useful for coral reef management.
Compact snapshot hyperspectral imaging with diffracted rotation

Traditional snapshot hyperspectral imaging systems include various optical elements: a dispersive optical element (prism), a coded aperture, several relay lenses, and an imaging lens, resulting in an impractically large form factor. We seek an alternative, minimal form factor of snapshot spectral imaging based on recent advances in diffractive optical technology. We thereupon present a compact, diffraction-based snapshot hyperspectral imaging method, using only a novel diffractive optical element (DOE) in front of a conventional, bare image sensor. Our diffractive imaging method replaces the common optical elements in hyperspectral imaging with a single optical element. To this end, we tackle two main challenges: First, the traditional diffractive lenses are not suitable for color imaging under incoherent illumination due to severe chromatic aberration because the size of the point spread function (PSF) changes depending on the wavelength. By leveraging this wavelength-dependent property alternatively for hyperspectral imaging, we introduce a novel DOE design that generates an anisotropic shape of the spectrally-varying PSF. The PSF size remains virtually unchanged, but instead the PSF shape rotates as the wavelength of light changes. Second, since there is no dispersive element and no coded aperture mask, the ill-posedness of spectral reconstruction increases significantly. Thus, we propose an end-to-end network solution based on the unrolled architecture of an optimization procedure with a spatial-spectral prior, specifically designed for deconvolution-based spectral reconstruction. Finally, we demonstrate hyperspectral imaging with a fabricated DOE attached to a conventional DSLR sensor. Results show that our method compares well with other state-of-the-art hyperspectral imaging methods in terms of spectral accuracy and spatial resolution, while our compact, diffraction-based spectral imaging method uses only a single optical element on a bare image sensor.
Chunks and Problem Solving Processes in an Expert's Play in a Card Game

Summary: In this study, we have focused on chunks which are configurations of tableau cards in a card game. We performed experiments on subjects to clarify how experts deal with the incomplete information problem, and examined the results. Regarding this card game, we suggest that a key of problem solving is the knowledge which controls the cycle of composition and recognition of flexible chunks.
A I ] 1 9 M ar 2 01 6 The Computational Power of Dynamic Bayesian Networks

This paper considers the computational power of constant size, dynamic Bayesian networks. Although discrete dynamic Bayesian networks are no more powerful than hidden Markov models, dynamic Bayesian networks with continuous random variables and discrete children of continuous parents are capable of performing Turing-complete computation. With modified versions of existing algorithms for belief propagation, such a simulation can be carried out in real time. This result suggests that dynamic Bayesian networks may be more powerful than previously considered. Relationships to causal models and recurrent neural networks are also discussed.
A Novel Reversible Data Hiding Technique in Image Processing

Communication plays a major role in the technological field. Data hiding is one such application of communication where a secrecy or protection is maintained throughout a particular communication. The project introduces a new technology for data hiding in image processing, called rhombus prediction embedding algorithm with boundary expansion. The project also made an implementation of the lossless compression of a location map that plays a major role in increased embedding efficiency. Also the embedding capacity for different images with different pixel values was calculated and compared using VHDL language. Later the entire hidden data was retrieved with making no change in the original image thereby showing perfection in data retrieval from the image after use. The entire data hiding system for a particular image has been analysed and implemented in ModelSim software in VHDL language and MATLAB.
How Is “ True ” Loyalty Expressed ?

This article deals with the outcomes of loyalty in performing arts. Research carried out at the Croix-Rousse Theatre in Lyon (France) shows that, on the contrary to previous works carried out on this theme, membership is not necessarily a proof of loyalty. Furthermore, it does not show a specificity of performing arts consumer behaviour concerning the outcomes of loyalty.
Number : WUCSE-2006-12 2006-0101 Virtualizing Network Processors

This paper considers the problem of virtualizing the resources of a network processor (NP) in order to allow multiple third-parties to execute their own virtual router software on a single physical router at the same time. Our broad interest is in designing such a router capable of supporting virtual networking. We discuss the issues and challenges involved in this virtualization, and then describe specific techniques for virtualizing both the control and data-plane processors on NPs. For Intel IXP NPs in particular, we present a dynamic, macro-based technique for virtualization that allows multiple virtual routers to run on multiple data plane processors (or micro-engines) while maintaining memory isolation and enforcing memory bandwidth allocations.

Exploring the measurement of entrepreneurial success indicators in a developing economy

Rigorous studies on entrepreneurial success indicators appear to be lacking in the developing economies. The indicators, often expressed in financial terms, are at best limited to a handful of case studies. Lack of information from business operators is the major constraint. This study attempts to explore ways of measuring entrepreneurial success indicators outside the finance domain particularly because of the understandably perceived belief by the business owners that any information to the outsider may have adverse effect on the business operations. The study employed survey design and curled data from a service sector of the Nigerian economy. Data for the study were analyzed using descriptive statistics. The result suggested certain success indicators outside the finance domain. The outcome of this study is capable of addressing the ‘misaligned relationship’, especially in information gathering between operators and advocates of entrepreneurship. This study has policy and theoretical implications.
MATHEMATICAL ENGINEERING TECHNICAL REPORTS Function Classes for Double Exponential Integration Formulas

The double exponential (DE) formulas for numerical integration are known to be highly efficient, more efficient than the single exponential (SE) formulas in many cases. Function classes suited to the SE formulas have already been investigated in the literature through rigorous mathematical analysis, whereas this is not the case with the DE formulas. This paper identifies function classes suited to the DE formulas in a way compatible with the existing theoretical results for the SE formulas. The DE formulas are good for more restricted classes of functions, but more efficient for such functions. Two concrete examples demonstrate the subtlety in the behavior of the DE formulas that is revealed by our theoretical analysis.
