Singular systems have been the subject of interest over the last two decades due to their many practical applications. But it has to be said that system identification of such system is still a challenging area because of the difficulty of identification of such systems for their complex structures. In addition, it seems that by developing a useful method for identification of singular system, one can use the useful property of such systems in describing the natural complex phenomena. This paper presents a novel methodology for identifying nonlinear singular systems from empirical data. Singular systems are idealized models for systems with slow and quick modes of change. However, their identification is a challenging problem even for the linear case. A new learning method, generalized locally linear model tree (GLoLiMoT) algorithm is introduced. The contribution of this paper is to provide a method for adjusting the parameters of fuzzy descriptor model, e.g. the splitting ratio and the standard deviation, the number of locally linear neurons or the number of linear singular systems for the consequent part in fuzzy descriptor model as well as the order of the singular system. By these modifications an accurate model of nonlinear singular system is obtained which is compared with several other methods in two case studies. Results depict the power of the proposed approach in describing nonlinear complex phenomena.

The quality of an approximation set usually includes two aspects-- approaching distance and spreading diversity. This paper introduces a new technique for assessing the diversity of an approximation to an exact Pareto-optimal front. This diversity is assessed by using an ldquoexposure degreerdquo of the exact Pareto-optimal front against the approximation set. This new technique has three advantages: Firstly, The ldquoexposure degreerdquo combines the uniformity and the width of the spread into a direct physical sense. Secondly, it makes the approaching distance independent from the spreading diversity at the most. Thirdly, the new technique works well for problems with any number of objectives, while the widely used diversity metric proposed by Deb would work poor in problems with 3 objectives or over. Experimental computational results show that the new technique assesses the diversity well.

Many protocols exist for supporting routing in mobile ad hoc networks (MANETs). Selecting a particular protocol for an application or deployment environment involves evaluating many complex inter-dependent tradeoffs and can be an overwhelming task for an application designer. However, this decision can have a significant impact on the success of a system in terms of performance, cost, and responsiveness. This paper introduces a design tool that automates this evaluation process by controlling for environmental and usage properties of an intended deployment. This provides the foundation for a highly adaptive protocol suite that lever-ages the relative benefits of competing communication paradigms. Copyright 2007 ACM.

Auxiliary potentials In chiral media

International Journal of engineering, Transactions A: Basics 2007年第2期20卷 147-158页

作者： Saraei, R. Rashed-Mohassel, J. Department of Electrical Engineering University of Kerman Kerman Iran Center of Excellence on Applied Electromagnetic Systems School of Electrical and Computer Engineering University of Tehran Tehran Iran

In the present paper, the expressions for scalar and vector potentials in lossless isotropic chiral media are analyzed. Propagating eigenvalues of these potentials are then obtained. Furthermore by decomposition of sources and fields in a chiral medium, we introduce the auxiliary right-and left-handed potentials and find the associated fields. These potentials are used to solve the problem of a horizontal electric dipole (HED) above a chiral half space. Auxiliary right and left handed Hertzian vector potentials are introduced and E and H fields in terms of these potentials are obtained. The Hertzian potentials due to VED and/or VMD sources within a chiral half space are determined in terms of two-dimensional Fourier spectral domain and the expressions for EM fields with respect to these potentials are presented.

A major problem in control over wireless networks is conceiving a joint control and communication system design to optimize a given cost function. To solve this problem we have recently proposed [1] a theoretical framework based on the Platform Based Design (PBD). The first step consists in mapping control specifications onto communication network specifications: this involves parameters as quantization noise, coding and modulation scheme, and power level. Next, a communication scheme is chosen so that the control specifications are satisfied. Hybrid models are exploited in order to capture the intrinsic discrete-continuous behaviors, and the developed framework is able to account for safety specifications that often occur in industrial control systems. While in our previous work we have been concerned with modeling efforts, in this paper we focus on the development of control methodologies and provide an example of application within a test case that is currently considered within the project HYCON. © 2007 IEEE.

Vertically aligned carbon nanotubes, embedded in titanium oxide, have been fabricated and their electron emission behavior has been characterized. The growth of carbon nanotubes was achieved using a dc plasma enhanced chemical vapor deposition method with a mixture of acetylene and hydrogen, and nickel was used as the catalyst layer. Titanium oxide, deposited using an atmospheric pressure chemical vapor deposition, was used to encapsulate the grown carbon nanotubes and the physical properties of the as-grown carbon nanotubes as well as the encapsulated structures have been investigated using scanning electron microscopy. By a sequential polishing and plasma ashing, it is possible to open up the top side of the encapsulated carbon nanotubes. Also by means of a reactive ion etching, carbon nanotubes are exposed with an inherent gate surrounding each one. This technique allows the evolution of individually processed nanotubes with no need of nanolithography. The emission of electrons from carbon nanotubes was examined and a preliminary field emission display was prepared. © 2007 American Vacuum Society.

The use of commercial off-the-shelf (COTS) software product can potentially reduce cost and time for software system development. But this promise is often not realized in practice because COTS product does not serve organizations' expectations. Thus, decision making on selecting COTS product becomes a critical task which should be performed in a systematic and repeatable manner. The decision analysis and resolution (DAR) process area of capability maturity model integration (CMMI) provides practices for formal evaluation process which could be applied to COTS selection. However, CMMI does not describe how to conduct the process that can achieve its defined goals. This research presents the DAR on COTS selection (DARCS) process model according to DAR process area of the CMMI. The model is consisted of three layers: core workflow layer, workflow details layer, and description layer.

Bad-Smell Metrics for Aspect-Oriented software

Bad-Smell Metrics for Aspect-Oriented Software

引用

International Conference on computer and Information Science (ACIS)

作者： Komsan Srivisut Pornsiri Muenchaisri Software Engineering Laboratory Center of Excellence in Software Engineering Department of Computer Engineering Faculty of Engineering Chulalongkom University Bangkok Thailand

Aspect-oriented programming (AOP) is a new programming paradigm that improves separation of concerns by decomposing the crosscutting concerns in aspect modules. Bad smells are metaphors to describe software patterns that are generally associated with bad design and bad programming of object-oriented programming (OOP). New notions and different ways of thinking for developing aspect-oriented (AO) software inevitably introduce bad smells which are specific bad design and bad programming in AO software called AO bad smells. software metrics have been used to measure software artifact for a better understanding of its attributes and to assess its quality. Bad-smell metrics should be used as indicators for determining whether a particular fraction of AO code contains bad smells or not. Therefore, this paper proposes definition of metrics corresponding to the characteristic of each AO bad smell as a means to detecting them. The proposed bad-smell metrics are validated and the results show that the proposed bad- smell metrics can preliminarily indicate bad smells hidden in AO software.
