Authors: Odd Inge Hillestad, Andrew Perkis, Vasken Genc, Seán Murphy, John Murphy
Venue: Proceedings of the 2nd ACM international workshop on Wireless multimedia networking and performance modeling (2006)

A simulation study of delivery of streaming video on-demand via IEEE 802.16 based technologies is described. A number of scenarios are simulated which are representative of rural area deployments of such technologies. The study finds that IEEE 802.16 can support up to 9/10 simultaneous users streaming typical cinematic video content in CIF resolution, 24 frames/s, at average rates of around 750 kbps. Further, the study demonstrates the utility of H.264/AVC Scalable Video Coding (SVC) and a buffer-based congestion control algorithm in an adaptive video streaming solution
An Efficient NAND Flash File System for Flash Memory Storage
Authors: Seung-Ho Lim, Kyu-Ho Park
Venue: IEEE Transactions on Computers (2006)

In this paper, we present an efficient flash file system for flash memory storage. Flash memory, especially NAND flash memory, has become a major method for data storage. Currently, a block level translation interface is required between an existing file system and flash memory chips due to its physical characteristics. However, the approach of existing file systems on top of the emulating block interface has many restrictions and is, thus, inefficient because existing file systems are designed for disk-based storage systems. The flash file system proposed in this paper is designed for NAND flash memory storage while considering the existing file system characteristics. Our target performance metrics are the system booting time and garbage collection overheads, which are important issues in flash memory. In our experiments, the proposed flash file system outperformed other flash file systems both in booting time and garbage collection overheads.

Authors: Satish Narayana Srirama, Matthias Jarke, Wolfgang Prinz
Venue: Proceedings of the 10th IEEE on International Enterprise Distributed Object Computing Conference Workshops (2006)

Web Services and mobile data services are the newest trends in information systems engineering in wired and wireless domains, respectively. Web Services have a broad range of service distributions while mobile phones have large and expanding user base. To address the confluence of Web Services and pervasive mobile devices and communication environments, a basic mobile Web Service provider was developed for smart phones. The performance of this Mobile Host was also analyzed in detail. Further analysis of the Mobile Host to provide proper QoS and to check Mobile Host's feasibility in the P2P networks, identified the necessity of a mediation framework. The paper describes the research conducted with the Mobile Host, identifies the tasks of the mediation framework and then discusses the feasible realization details of such a mobile Web Services mediation framework.
Multi-agent based peer-to-peer information retrieval systems with concurrent search sessions
Authors: Haizheng Zhang, Victor Lesser
Venue: Proceedings of the fifth international joint conference on Autonomous agents and multiagent systems (2006)

In cooperative peer-to-peer information retrieval systems, each node can be considered an intelligent agent and these agents work collectively to provide an information retrieval service. In order to effectively support multiple and concurrent search sessions in the network, we propose two traffic engineering techniques that minimize processing and communication bottlenecks. One is a novel agent control mechanism whose elements include resource selection, local search scheduling, and feedback-based load control. The other is a new two-phase query routing algorithm based on organizational knowledge. Experimental results show that this framework can reduce congestion situations, increase system throughput, and improve considerably the overall system utility.

Authors: Deepak Mishra, N. Subhash Chandra Bose, Arvind Tolambiya, Ashutosh Dwivedi, Prabhanjan Kandula, Ashiwani Kumar, Prem K. Kalra
Venue: Proceedings of the 9th International Conference on Information Technology (2006)

A modified forward-only counterpropagation neural network (MFO-CPN) for color image compression is proposed. It uses several higher-order distance measures for calculating winning node. It also incorporates nonlinear adjustment of learning rates in both the layers. Results with these distance functions are compared. Proposed modifications leads to improvement in the image quality and faster convergence of network.

On the stability and vibrational stabilization of a class of nonlinear systems
Authors: A. Yu. Aleksandrov, A. V. Platonov
Venue: Proceedings of the 2003 International Conference on Physics and Control - Volume 2 (2003)

A certain class of nonlinear oscillatory systems is investigated. The method of construction of Lyapunov's functions is suggested to obtain sufficient conditions of asymptotic stability and instability of the equilibrium position for systems considered. The influence of the nonautonomous perturbations on the asymptotic behavior of solutions is studied. The conditions under which the equilibrium position may be stabilized by means of the periodic variations of system parameters are investigated.
Improving software testing by observing practice
Authors: Ossi Taipale, Kari Smolander
Venue: Proceedings of the 2006 ACM/IEEE international symposium on Empirical software engineering (2006)

The objective of this qualitative study was to understand the complex practice of software testing, and based on this knowledge, to develop process improvement propositions that could concurrently reduce development and testing costs and improve software quality. First, a survey of testing practices was onducted and 26 organizational units (OUs) were interviewed. From this sample, five OUs were further selected for an in-depth case study. The study used grounded theory as its research method and the data was collected from 41 theme-based interviews. The analysis yielded improvement propositions that included enhanced testability of software components, efficient communication and interaction between development and testing, early involvement of testing, and risk-based testing. The connective and central improvement proposition was that testing ought to adapt to the business orientation of the OU. Other propositions were integrated around this central proposition. The results of this study can be used in improving development and testing processes.
Robust Handling of Multiple Multi-Objective Optimisations
Authors: Wolfgang Ponweiser, Markus Vincze
Venue: Proceedings of the Second IEEE International Conference on e-Science and Grid Computing (2006)

To enable the selection of methods in any domain, a detailed and context dependent performance description of the methods is required. In cases, where this description has to be generated by an evaluation, the introduction of context can be done cleverly without increasing the number of evaluation runs. However the more detailed performance evaluation delivers several objective entries for one test case. This results in a new type of problem, a multiple multiobjective optimisation. This paper presents a novel genetic algorithm and a novel performance metric that deals with the specific of this type of problem in a robust way.
MUIA 2006: third international workshop on mobile and ubiquitous information access
Authors: Fabio Crestani, Matt Jones, Stefano Mizzaro
Venue: Proceedings of the 8th conference on Human-computer interaction with mobile devices and services (2006)

The recent trend towards pervasive computing and information technology becoming omnipresent and entering all aspects of modern living, means that we are moving away from the traditional interaction paradigm between human and technology being that of the desktop computer. This shift towards ubiquitous computing is perhaps most evident in the increased sophistication and extended utility of mobile devices, such as mobile phones, PDAs, mobile communicators (telephone/PDA) and Tablet PCs. Advances in these mobile device technologies coupled with their much-improved functionality means that current mobile devices can be considered as multi-purpose information access tools capable of complex tasks. This Third Workshop on Mobile and Ubiquitous Information Access (MUIA 2006) aims to be a forum for the presentation of current research and exchange of experiences into technological and usability aspects of mobile information access.

Authors: Arlindo Neto Montagnoli, Jose Benaque Rubert, Rodrigo Capobianco Guido, Jose Carlos Pereira
Venue: Proceedings of the Eighth IEEE International Symposium on Multimedia (2006)

In this work a computational method is presented to simulate the movements of vocal folds in three dimensions. The proposed model consists of a mesh free structure where each vertex is connected its neighbor through a group spring-damper. Forced oscillations were studied by time varying surface forces. The preliminary results using this model are similar with the literature and with the experimental stroboscopic observations of larynx.
Transforming Natural Arguments in Araucaria to Formal Arguments in LMA
Authors: Yohsuke Takahashi, Hajime Sawamura, Jing Zhang
Venue: Proceedings of the IEEE/WIC/ACM international conference on Intelligent Agent Technology (2006)

Over the last few years, argumentation has been gaining increasing importance in multi-agent systems research. LMA is a Logic of Multiple-valued Argumentation built on top of EALP (Extended Annotated Logic Programming). Araucaria is a software tool for analyzing and diagramming arguments written in natural language. We integrate these two systems involved in argumentation to an easy to use and more user-friendly argumentation system, in which natural arguments can be transformed into formal arguments, in order to lighten users' knowledge burden forced by formal argumentation frameworks, and attain extensive usability of formal argumentation systems. We illustrate the transformation process by translating natural arguments in English to formal arguments in EALP step-by-step, and then how the status of those formal arguments can be determined in LMA, resulting in the status determination of original natural arguments.

Venue: Proceedings of the 26th IEEE International ConferenceWorkshops on Distributed Computing Systems (2006)

Since various disasters provides serious damage influence at the time to many residents in wide area across Japan island, large scale of disaster information system with more robustness and redundancy covered over wide area is required. In this paper, we introduce a large scale distributed resident-oriented safety information system constructed over Japan Gigabit Network. The safety information with residents is registered to the local database in the evacuated area and integrated into an upper-layer database in the district area. Those local databases are mutually covered when the some of the databases are destroyed or disordered. On the other hand, the upper-layer databases are located to mutually different locations with long distance to isolate the influence to the same disaster and also mutually mirrored to support when the some of them are out of order. Thus, by introducing two levels of redundancy and backup functions, more large scale and robust safety information database system can be realized. In this paper, we designed and implemented a prototype system by our introduced method over Japan Gigabit Network to evaluate whether our suggested method is useful or not. Through the functional and performance evaluation, we could verified our suggested resident information system is effective and useful.
On the Assessment of the Mean Failure Frequency of Software in Late Testing
Authors: Sandro Morasca
Venue: Proceedings of the International Conference on Software Engineering Advances (2006)

We propose an approach for assessing the mean failure frequency of a program, based on the statistical test of hypotheses. The approach can be used to establish stopping rules and evaluate the quality of a program based on its mean failure frequency during the late testing phases. Our proposal shows how to set and satisfy conservative bounds for the minimum number of test executions that are needed to achieve a target mean failure frequency with a specified level of statistical significance, based on the quality goal of testing and the specific test execution profile chosen. We relax a few assumptions of the literature, so our approach can be used in a larger set of real-life cases.
'Rough Consensus and Running Code' and the Internet-OSI Standards War

Venue: IEEE Annals of the History of Computing (2006)

Internet historians recognize the technical achievements but often overlook the bureaucraticinnovations of Internet pioneers. The phrase, "We reject: kings, presidents, and voting. We believein: rough consensus and running code," was coined by David Clark in 1992. This article explains howthe phrase captured the technical and political values of Internet engineers during a crucial phasein the Internet's growth.
WorldMirror and WorldBottle: Components for Interaction between Multiple Spaces in a 3D Virtual Environment
Authors: Masahiko ITOH, Makoto OHIGASHI, Yuzuru TANAKA
Venue: Proceedings of the conference on Information Visualization (2006)

This paper proposes a new concept and mechanism for the user and content interaction between multiple spaces in a 3D virtual environment. We introduce two types of visual components; a flat, window-like WorldMirror, and a volumetric WorldBottle. These components embed other spaces inside and render them on their surface, so that users can look into the contents of other spaces from their current working one and choose to enter. They also allow content manipulation in embedded spaces from the current space. Users can move an object from an embedded space to the current working space, or drop an object from the current space into an embedded space. In contrast to conventional approaches, the proposed mechanism enables us not only to define a spatial connection between different spaces, but also to define a functional linkage among components in different spaces.
Disjoint Paths Routing in Pancake Graphs
Authors: Keiichi Kaneko, Shietung Peng
Venue: Proceedings of the Seventh International Conference on Parallel and Distributed Computing, Applications and Technologies (2006)

In this paper, we propose efficient algorithms that find disjoint paths for node-to-node and node-to-set routing in pancake graphs. For an n-pancake graph, the algorithms can find n - 1 disjoint paths of small maximum length with optimal time complexity. That is, the n-1 paths can be constructed in O(n^2 ) time and the maximum length is bounded by 5n/3 + 6.
A Feature-based Approach to Electronic Contracts
Authors: Marcelo Fantinato, Maria Beatriz F. de Toledo, Itana Maria de S. Gimenes
Venue: Proceedings of the The 8th IEEE International Conference on E-Commerce Technology and The 3rd IEEE International Conference on Enterprise Computing, E-Commerce, and E-Services (2006)

E-contracts are used to describe the supply and the consumption details of e-services within a business process. The establishment of e-contracts in a given application domain usually involves a set of welldefined common and variation points. This paper proposes a feature-based approach in order to decrease the complexity in e-contract establishment and to foster inter-organizational cooperation. Feature modeling is a technique that has been widely used for capturing and managing commonalities and variabilities of product families in the software product line context. The feasibility of the approach is shown by a case study carried out within the telecom context and based on experimental software engineering concepts.

Venue: Proceedings of the XIII Asia Pacific Software Engineering Conference (2006)

Testing for time-related behaviors of PLC software is important and should be performed carefully. We propose a structural testing technique on Function Block Diagram(FBD) networks including timer function blocks. In order to test FBD networks including timer function blocks, we generate templates for timer function blocks and transform a unit FBD into a flowgraph using the proposed templates. We apply existing testing techniques to the generated flowgraph and describe how the characteristics of timer function blocks are reflected in the testing process. By the proposed method, FBD networks including timer function blocks can be tested thoroughly without the intermediate code which was essential in the previous FBD testing. To demonstrate the effectiveness of the proposed method, we use a trip logic of bistable processor of digital plant protection systems which is being developed in Korea.
Modelling dynamics of cognitive agents by higher-order potentialities
Authors: Tibor Bosse, Jan Treur
Venue: Proceedings of the fifth international joint conference on Autonomous agents and multiagent systems (2006)

In the development of disciplines addressing dynamics, such as Mathematics and Physics, a major role was played by the assumption that processes can be modelled by introducing certain state properties (also called potentialities) that anticipate in which respect a next state will be different. The current paper is a first exploration of this perspective to analyse and model dynamics. Potentiality-based modelling subsumes quantitative, numerical modelling approaches, such as Dynamical Systems Theory (DST), and qualitative or symbolic modelling approaches to dynamics, such as BDI-modelling, and is applicable to model dynamics in a wide variety of (cognitive and noncognitive) disciplines. Thus, the modelling of dynamics of cognitive agents can be fully integrated with the modelling of other phenomena in Nature.
An Embedded Methodology for FPGAs' Digital Distance Relay Design and Analysis
Authors: Tsair-Fwu Lee, Ming-Yuan Cho, Ying-Chang Hsiao, Hong-Jen Lee
Venue: Proceedings of the 2006 International Conference on Hybrid Information Technology - Volume 01 (2006)

This paper proposes a methodology for distance relay design to detect the fault location and mark out the protective region. We followed the intellectual property (IP) cores concept in system on chip to accomplish the development of an intelligent digital distance relay. Therefore, the field programmable gate arrays (FPGAs) technique was applied to design and implement the digital distance relay associated with the proposed method. In additional to verify the validation of the digital distance relay, we compare the result with Matlab simulation check. Then we concluded the performance of the designed distance relay is indeed superior in speed and accuracy with flexibility.
Agile Software Testing in a Large-Scale Project
Authors: David Talby, Orit Hazzan, Yael Dubinsky, Arie Keren
Venue: IEEE Software (2006)

Agile software development implies major changes in the way you test software, from strategic project planning to day-to-day activities. While previous publications focus on programmer-oriented practices, such as test-first programming, they've neglected many issues related to large-scale projects and to an organization's initial transition to agile methods. This article attempts to close this gap, reporting on the Israeli Air Force's Extreme Programming experiences in a large-scale, enterprise-critical software project. Along with qualitative and quantitative data that validates agile testing practices, the article presents guidelines for test design and execution, working with professional testers, planning the quality process, and defect management.This article is part of a special issue on Software Testing.
Evaluating advantages of test driven development: a controlled experiment with professionals
Authors: Gerardo Canfora, Aniello Cimitile, Felix Garcia, Mario Piattini, Corrado Aaron Visaggio
Venue: Proceedings of the 2006 ACM/IEEE international symposium on Empirical software engineering (2006)

Test driven development (TDD) is gaining interest among practitioners and researchers: it promises to increase the quality of the code. Even if TDD is considered a development practice, it relies on the use of unit testing. For this reason, it could be an alternative to the testing after coding (TAC), which is the usual approach to run and execute unit tests after having written the code. We wondered which are the differences between the two practices, from the standpoint of quality and productivity. In order to answer our research question, we carried out an experiment in a Spanish Software House. The results suggest that TDD improves the unit testing but slows down the overall process.
A parameterized graph-based framework for high-level test synthesis
Authors: Saeed Safari, Amir Hossein Jahangir, Hadi Esmaeilzadeh
Venue: Integration, the VLSI Journal (2006)

Improving testability during the early stages of high-level synthesis has several benefits including reduced test hardware overheads, reduced test costs, reduced design iterations, and significant improved fault coverage. In this paper, we present a novel register allocation method, which is based on weighted graph coloring algorithm, targeting testability improvement for digital circuits. In our register allocation method, several high-level testability parameters including sequential depth, sequential loop, and controllability/ observability are considered. Our experiments show using this register allocation method results in significant improvement in automatic test pattern generation time and fault coverage.
Online Identity as a Leverage Point for Learning in Massively Multiplayer Online Role Playing Games (MMORPGs)
Authors: Joey J. Lee, Christopher M. Hoadley
Venue: Proceedings of the Sixth IEEE International Conference on Advanced Learning Technologies (2006)

Several researchers have argued for the use of games in the classroom because they are engaging and provide many valuable learning opportunities. In many cases, however, edutainment has failed. This paper argues that not enough attention has been given to video games' role in identity development and exploration, important corequisites for learning. A case study of a five-week course is included, in which fourteen students participated in two massively multiplayer online games (MMORPGs) as a technology for identity and learning. We propose that identity may be the key to transcending the engagement/learning tradeoff in educational gaming.
