The 2004 Joint Conference of the 10～(th) Asia-Pacific Conference on Communications and the 5～(th) International Symposium on Multi-Dimensional Mobile Communications

作者： Atushi Kubota Doctoral Program in Science & Information Engineering University of Tsukuba Tsukuba Science City Ibaraki 305-8573 Japan

This paper addresses the dynamic location management for personal communication sen'ice (PCS) networks with popular hexagonal celluar architectures. We first introduce a coordinate system for the hexagonal celluar architectures. Then, we develop an all-direction mobility model based on the coordinate system for the hexagonal cellular architecture to cope with the mobility patterns of mobile terminals (MTs). By using the proposed model, the shape and size of the local area in the dynamic location update scheme are determined optimally.

A Proposal of GA Using Symbiotic Evolutionary Viruses and its Virus Evaluation Techniques

Journal of Advanced Computational Intelligence and Intelligent Informatics 2004年第4期8卷 421-425页

作者： Sakakura, Yoshiaki Taniguchi, Noriyuki Hoshino, Yukinobu Kamei, Katsuari Frontier Doctoral Program in Science and Engineering Ritsumeikan University Japan Graduate School of Science and Engineering Ritsumeikan University Japan Human and Computer Intelligence College Information Science and Engineering Ritsumeikan University 1-1-1 Noji-higashi Kusatsu Shiga525-8577 Japan

In this paper, we propose a Genetic Algorithm (GA) using symbiotic evolutionary viruses based on both the building block hypothesis and the virus theory of evolution. The proposed GA aims to control the destruction of building blocks by discovery, maintenance, and propagation of building blocks based on virus operation. We prepare a group of individuals and a group of viruses. The group of individuals searches for solutions and the group of viruses searches for building blocks. These searches are done based on the symbiotic relation of both groups. Also, our GA has two types of virus evaluation technique. In one type, each virus is evaluated by the difference of the fitness of an individual before and after virus infection. In the other type, all viruses are evaluated by the difference of the fitness of an individual before and after infection of all viruses. We applied the proposed GA to a minimum value search problem using a test function with some local minima far from the optimum. Finally, we also discuss the search behavior in the proposed GA based on each virus evaluation technique. © Fuji Technology Press Ltd.

The relationship between surface structure and permeability property of soy protein and mungbean protein film was carried out using atomic force microscopy (AFM). The increasing of film porosity resulting in increasing of water vapor permeability (WVP) of films. AFM images showed that the surface of soy protein film was rougher than that of mungbean protein. Films with high glycerol concentration has a rough surface because of the lower evaporation

A Moment-Based Method for Large-Scale Generalized Eigenvalue Problems

引用

Applied Numerical Analysis & Computational Mathematics 2004年第2期1卷

作者： Tetsuya Sakurai Hiroto Tadano Yuichi Inadomi Umpei Nagashima Department of Computer Science University of Tsukuba Tsukuba 305-8573 Japan Core Research for Evolutional Science and Technology Japan (CREST) Doctoral Program of Systems and Information Engineering University of Tsukuba Tsukuba 305-8573 Japan Grid Technology Research Center National Institute of Advanced Industrial Science and Technology Tsukuba 305-8568 Japan

In this paper we consider a method for finding several eigenvalues and corresponding eigenvectors of large-scale generalized eigenvalue problems. In this method, a small matrix pencil that has only the desired eigenvalues is derived using complex moments obtained via numerical integration. Since the process to derive the moments can be performed in parallel and we do not need to exchange data between processes, the presented method is suitable for master-worker programming models. We have implemented and tested the proposed method in a grid RPC (remote procedure call) system. Numerical examples illustrate the properties of our approach. (© 2004 WILEY-VCH Verlag GmbH & Co.

We address mobility management for the Internet Protocol version 6 in mobile networks, namely Mobile IPv6 (MIPv6). To correctly transfer IPv6 packets to a mobile node (MN), the MN has to update its binding to the home network while roaming away from its home network. Mobile IP networks suffer high binding update traffic from high rates of handoffs and the long packet delivery delay from the large distance to the home network. In this paper, we introduce a dynamic and distributed mobility management protocol for MIPv6 to reduce the binding update and packet delivery delay and traffic. We describe the basic protocol operations, and examine the performance improvement of our mobility management against the previous Mobile IP mobility management methods. We show that the dynamic and distributed mobility management method outperforms other previous methods, and the dynamic approach provides the optimal mobility solution for MIPv6 and the distributed approach can decentralize the network load. ©2003 IEEE.

This paper addresses caching for location management in personal communication service (PCS) networks. Caching is useful to reduce the delay of locating frequently retrial calls to a mobile user. However, the cached information may be obsolete due to the mobility of mobile users, which is the reason for the degradation of system performance. We introduce an efficient caching scheme for dynamic location management to improve the location management performance. Moreover, we establish an analytical model and perform a performance evaluation to study the performance improvement of the caching scheme over the non-caching scheme. We provide a simple and direct way of caching based on dynamic location management.

A boundary tracking method crucial to function approximation-based image coding is proposed that solves the problems caused by duplicate tracking the common boundaries of color regions when methods conventionally applied to bilevel raster images are inappropriately used. Experimental evaluation is performed to verify its effectiveness.

On Classifying Daylight for Design

International Journal of Architectural Computing 2003年第2期1卷 205-217页

In this paper, we present LiQuID, a tool for clustering lighting simulation data. Photographs are useful vehicles for both describing and making assessments of architectural lighting systems. A significant barrier to using photographs during the design process relates to the sheer volume of renderings that needs to be analyzed. Although there have been efforts to produce novel visualization systems to manage large sets of photographs, this research aims to reduce the complexity by classifying data into representative prototypes. A hypothetical case study is discussed.
