Simulation Winter Conference

作者： F. Maymi J. Surdu A. Hall R. Beltamini Dep. of Electrical Engineering and Computer Science United States Military Academy West Point NY U.S.A. Department of Mathematical Sciences United States Military Academy West Point NY U.S.A.

The United States Army is designing and implementing a revolutionary advance in the combat power of individual infantrymen on the battlefield: Land Warrior. In Land Warrior, each soldier becomes a node in a wireless local area network (WLAN). In order to account for likely losses of line of site between soldiers, the On Demand Multicast Routing Protocol (ODMRP) is used. The purpose of this research was to construct a simulation study to determine whether the communications architecture of Land Warrior was sufficiently scalable to use in large Army units. This paper describes the input analysis conducted to determine probability distributions used to generate message traffic. This paper also describes the development of the simulation model used to determine the scalability of the Land Warrior communications architecture.

IEEE International Conference on Fuzzy Systems (FUZZ-IEEE)

作者： A. Ciaramella R. Tagliaferri W. Pedrycz Dep. of Mathematics and Computer Science University of Salerno Baronissi Salerno Italy Dep. of Electrical and Computer Engineering University of Edmonton Canada

In this paper, a neuro-fuzzy model is introduced. The model describes a fuzzy relational "IF-THEN" reasoning scheme using an adaptive structure based on fuzzy relations. Two training schemes for the learning of the parameters based respectively on the backpropagation algorithm and pseudo-inverse matrix technique are illustrated. The model qualities are investigated by a series of simulation examples: function approximation, classification and rule extraction. These preliminary and promising results show that the model has a good performance and that it could be used for complex systems in real world applications.

The practical implementation of the third-order tetrahedral version of Nedelec's first family of curl-conforming elements is presented. Following the definition of the element given by Nedelec, the third-order vectorial basis functions of the element are deduced. The element thus obtained exhibits some important differences with respect to other higher-order curl-conforming elements which have appeared in the literature. Specifically, the third-order curl-conforming finite element proposed leads to better conditioned finite element method (FEM) matrices.

Due to visibility change and surface enlargement in producing a novel view from a new viewpoint, 3D re-projection from one reference image in IBMR inevitably produces holes in the destination image. Even worse, exposure errors occur when a background region occluded is visible in a desired image because of the absence of some background elements in the reference image. The general solution to this kind of problems is to use multiple images from different viewpoints as input source. By doing so however, the rendering cost would increase with the number of reference images and the composition algorithm has to rely on the z-buffer processing. In fact, plenty of redundant information exists among different reference images. Seeking for a nice way to extract the information needed in the novel view from the reference images is the key issue in solving the problem. In this paper, we propose a new method of image synthesis from multiple reference images. The method combines forward warping and backward warping to fulfil the image composition task for a novel viewpoint. The primary inspiration behind the development of our image synthesis method comes from a fact that the polygon edge geometry may indicate where an exposure and, possible an exposure error occur in the destination image if object silhouettes are prior known. The feature that intersection between scanline and polygons must be in pairs is employed to distinguish holes caused by enlargement of surfaces from those by visibility change. Different heuristic methods are used m choose one image as a primary reference image which shares the most resemblance with the destination image, and other reference images for filling different kinds of holes. dep.h continuity along scanline and the dep.h information already present in the destination image are employed to accelerate the searching process of the corresponding pixels for filling holes. © ACM 2000.

We present an intuitive and simple O(log2 n log φ) time, O(n2M(n)) processer parallel algorithm for finding a perfect matching in a planar graph, where n is the order, π is the number of the distinct perfect matchings of the graph and M(n) is the best sequential complexity of matrix multiplication of size n. The algorithm runs on a CRCW PRAM. Clearly, our algorithm belongs to the class NC if the number of perfect matchings is polynomially bounded in the size of the input graph.

Hand gesture is one of the most natural and expressive ways for the hearing impaired. However, because of the complexity of dynamic gestures, most researches are focused either on static gestures, postures, or a small set of dynamic gestures. As real-time recognition of a large set of dynamic gestures is considered, some efficient algorithms and models are needed. To solve this problem in Taiwanese Sign Language, a statistics based context sensitive model is presented and both gestures and postures can be successfully recognized. A gesture is decomposed as a sequence of postures and the postures can be quickly recognized using hidden Markov model. With the probability resulted from hidden Markov model and the probability of each gesture in a lexicon, a gesture can be easily recognized in a linguistic way in real-time. © 2000 Association for Computing Machinery.

An artificial‐neural‐network (ANN) application for steady‐state security evaluation of electrical power systems is presented. Such application is based upon a combined use of a multilayer back‐propagation neural network and of an opportune electrical system model, previously proposed by some of the authors. In the paper, the definition of steady‐state security and the problems arising from its on‐line evaluation are briefly recalled. Then, the ANN utilized is described with particular reference to the solutions adopted by the authors. Afterwards, some remarks on the system model utilized are reported. Finally, numerical applications on the AEP‐14 bus system are presented and the results obtained with different ANN configurations are analyzed. Copyright © 1995 John Wiley & Sons, Ltd.

A new multidisciplinary effort is linking research in the upper atmospheric and space, computer, and behavioral sciences to develop a prototype electronic environment for conducting team science worldwide. A real‐world electronic collaboration testbed has been established to support scientific work centered around the experimental operations being conducted with instruments from the Sondrestrom Upper Atmospheric Research Facility in Kangerlussuaq, Greenland. Such group computing environments will become an important component of the National Information Infrastructure initiative, which is envisioned as the high‐performance communications infrastructure to support national scientific research. ©1994.
