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

引用

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.

Embedded vertically grown carbon nanotubes for field emission applications

Journal of Vacuum Science and Technology B: Microelectronics and Nanometer Structures 2007年第3期25卷 822-828页

作者： Abdi, Yaser Koohshorkhi, Javad Mohajerzadeh, Shams Darbari, Sara Sanaee, Zeinab Nano-Electronic Center of Excellence Nano-Electronic and Thin Film Laboratory University of Tehran Tehran Iran Department of Electrical and Computer Engineering University of Tehran Tehran Iran

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.

Mobile agent systems of the future will be used for secure information delivery and retrieval, off-line searching and purchasing, and even system software updates. As part of such applications, agent and platform integrity must be maintained, confidentiality between agents and the intended platform parties must be preserved, and accountability of agents and their platform counterparts must be stringent. SMASH, Secure Modular Mobile Agent System.H, is an agent system designed using modular components that allow agents to be easily constructed and the system to be easily extended. To facilitate security functionality, the SMASH platform incorporates existing hardware and software security solutions to provide access control, accountability, and integrity. Agents are further protected using a series of standard cryptographic functions. While SMASH promotes high assurance applications, the system also promotes an open network environment, permitting agents to move freely among the platforms and execute unprivileged actions without authenticating. In this paper, we elaborate on the components and capabilities of SMASH and present an application that benefits from each of these elements. © Springer-Verlag Berlin Heidelberg 2007.

One of the highest priorities of system requirements needed in software development industry is security requirements. However, to identify the complete and correct software security requirements are a challenging task especially creating enterprise assets security requirements. Enterprise assets security requirements are to identify security basic needs, to assess risks, to establish security approach and service, and to specify external enterprise consideration including confidentiality, integrity, availability, and accountability concerns. Moreover, these may be applied to other security requirements such as identification and authentication, access control, firewall architecture, etc. Security patterns may be used to create this security requirements but understanding, analyzing and transforming from security patterns to security requirements are difficult to accomplish. We proposed a grammar, called ESRMG (enterprise security and risk management grammar), and a prototyping tool based on security patterns in a scope of enterprise asset identification and risk managements which are the fundamental of enterprise security requirements. The proposed grammar and tool are beneficial for any organization to construct enterprise security requirements and may help reduce cost and time in overall of system development.
