Oriya Handwritten Numeral Recognition Syste
Authors: K. Roy, T. Pal, U. Pal, F. Kimura
Venue: Proceedings of the Eighth International Conference on Document Analysis and Recognition (2005)

This paper deals with recognition of off-line unconstrained Oriya handwritten numerals. To take care of variability involved in the writing style of different individuals, the features are mainly considered from the contour of the numerals. At first, the bounding box of a numeral is segmented into few blocks and chain code histogram is computed in each of the blocks. Features are mainly based on the direction chain code histogram of the contour points of these blocks. Neural Network (NN) classifier and quadratic classifier are used separately for recognition and the results obtained from these two classifiers are compared. We tested the result on 3850 data collected from different individuals of various background and we obtained 90.38% (94.81%) recognition accuracy from NN (quadratic) classifier with a rejection rate of about 1.84% (1.31%), respectively.

Authors: Guillermo de Jesus Hoyos-Rivera, Roberto Willrich
Venue: Proceedings of the 14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (2005)

Collaborative Web Browsing aims at extending currently available Web browsing capabilities in order to allow several users getting their browsing activities synchronized. A Collaborative Web Browsing system should provide all the necessary facilities to allow users to get synchronized and desynchronized in a flexible way, including both browsing actions and browser embedded presentations interactions. In this paper we present the modeling and implementation of our Collaborative Web Browsing system called CoLab 2. It implements the necessary functionalities that allow solving the problem of allowing users to collaboratively browsing the Web.
Recovery During Concurrent On-Line Testing of Identical Circuits
Authors: Irith Pomeranz, Sudhakar M. Reddy
Venue: Proceedings of the 20th IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems (2005)

We show that a concurrent on-line testing scheme based on output comparison of identical circuits can also identify situations where the circuit recovers from a permanent fault, i.e., functional operation can continue temporarily in spite of the presence of a fault. We show that the ability to recover from a fault is circuit-dependent, and that some circuits are better than others at allowing recovery. We also discuss the possibility of false recovery in the presence of multiple faults and its implications.
Page Segmentation for Manhattan and Non-Manhattan Layout Documents via Selective CRLA
Authors: Hung-Ming Sun
Venue: Proceedings of the Eighth International Conference on Document Analysis and Recognition (2005)

The Constrained Run-Length Algorithm (CRLA) is a well-known technique for page segmentation. The algorithm is fast and can be used to partition documents with Manhattan layouts. It is not, however, suited to deal with pages with layouts beyond the Manhattan format, e.g. irregular halftone images embedded in text paragraphs. A modified version of the CRLA, named selective CRLA, is presented in this paper. The selective CRLA is capable of processing documents with both Manhattan and non-Manhattan layouts. The selective CRLA is performed twice with different sets of parameters on a label image derived from the input document image. After both of its executions, the yielded text regions are extracted. The proposed method has been successfully applied to extraction of text from commercial magazine pages with complicated layouts.

Authors: Maciej Piasecki, Ireneusz Matysiak, Anna Rusak
Venue: Proceedings of the 5th International Conference on Intelligent Systems Design and Applications (2005)

Our paper presents a modular architecture for a natural dialogue system. The architecture is applied in the construction of Logo - a dialogue system for Polish, based on the Discourse Representation Theory[4], implementing some aspects of the pragmatic analysis and enabling communication with an agent acting in the virtual reality of a blocks world. Logo deals also with the selected issues of coreference resolution. The proposed architecture is intended to be flexible and open for utilisation of diverged language resources.
VQ-RED: An Efficient Virtual Queue Management Approach to Improve Fairness in Infrastructure WLAN
Authors: Xiaoyang Lin, Xiaolin Chang, Jogesh K. Muppala
Venue: Proceedings of the The IEEE Conference on Local Computer Networks 30th Anniversary (2005)

In this paper, we consider two fairness problems (downlink/uplink fairness and fairness among flows in the same direction) that arise in the infrastructure WLAN. We propose a virtual queue management approach, named VQ-RED to address the fairness problems. We demonstrate the effectiveness of our approach by conducting a series of simulations. The results show that compared with standard DCF, VQRED not only greatly improves the fairness, but also reduces packet delays.
Distributed User Interface Elements to support Smart Interaction Spaces
Authors: Kris Luyten, Karin Coninx
Venue: Proceedings of the Seventh IEEE International Symposium on Multimedia (2005)

In this paper we show how an interactive system can be distributed among several peer devices. By taking advantage of the current trend towards ambient intelligent environments, we can make use of a combination of computing resources in the surrounding of the user to function as one logical interactive system; an interaction space. Our approach relies on the fact that nowadays most computing resources are network-enabled and publish their device pro- file using some special-purpose protocol. For this reason, federations of devices that support the tasks of the user can be composed automatically according to the requirements of these tasks. This distribution of the user interface over a federation of devices can be local or non-local. It raises the opportunity for supporting collaborative tasks with the same user interface with little or no extra effort from the user interface designer. Future tools supporting the design, creation and deployment of distributed interactive systems using device federations should maintain usability and usefulness of a dynamic distributed system. We use two different metrics to cope with these problems: interface completeness and interface continuity.
Bringing Mobility to Synchronous Collaborative Activities: Recent Enhancements of the "Platine" Platform
Authors: David Raymond, Yoneo Yano, Carlos Eduardo Mauad, Veronique Baudin-Thomas, Thierry Gayraud, Michel Diaz, Kazuhide Kanenishi, Kenji Matsuura
Venue: Proceedings of the IEEE International Workshop on Wireless and Mobile Technologies in Education (2005)

The interests of synchronous communications in collaborative activities have been recognized by an important number of researches and experiments. Some environments offer the use of synchronous communications as a collaborative learning solution for a group of distributed users. Each user is independent from the other and joins a collaboration activity by his/her own. Such kind of environments is only available for desktop computers. This constraint limits the use of synchronous communications for learning activities. Some activities such as situated learning would benefit from synchronous collaboration technologies. This paper presents a technical solution for mobile synchronous learning activities. First, we introduce educational situations that take advantage of mobility to stimulate participation of the user. Then, we present the technical solution "Platine" developed by the LAAS-CNRS. Platine is a synchronous collaborative learning environment previously developed for desktop or notebook computers. A specific client has been developed for Personal Digital Assistant (PDA).

Requirements quality control: a unifying framework
Authors: Artem Katasonov, Markku Sakkinen
Venue: Requirements Engineering (2005)

Literature tends to discuss software (and system) requirements quality control, which includes validation and verification, as a heterogeneous process using a great variety of relatively independent techniques. Also, process-oriented thinking prevails. In this paper, we attempt to promote the point that this important activity must be studied as a coherent entity. It cannot be seen as a rather mechanical process of checking documents either. Validation, especially, is more an issue of communicating requirements, as constructed by the analysts, back to the stakeholders whose goals those requirements are supposed to meet, and to all those other stakeholders, with whose goals those requirements may conflict. The main problem, therefore, is that of achieving a sufficient level of understanding of the stated requirements by a particular stakeholder, which may be hindered by, for example, lack of technical expertise. In this paper, we develop a unifying framework for requirements quality control. We reorganize the existing knowledge around the issue of communicating requirements to all the different stakeholders, instead of just focusing on some techniques and processes. We hope that this framework could clarify thinking in the area, and make future research a little more focused.

This book is the first detailed survey of developments in this field; it is an excellent resource for anyone interested in learning about the topic, as well as a practitioner or researcher seeking a quick reference. Users of statistical analysis and optimization CAD tools will find it invaluable because it provides the background required to separate the wheat from the chaff.
An evolutionary learning approach for adaptive negotiation agents: Research Articles
Authors: Raymond Y. K. Lau, Maolin Tang, On Wong, Stephen W. Milliner, Yi-Ping Phoebe Chen
Venue: International Journal of Intelligent Systems (2006)

Developing effective and efficient negotiation mechanisms for real-world applications such as e-business is challenging because negotiations in such a context are characterized by combinatorially complex negotiation spaces, tough deadlines, very limited information about the opponents, and volatile negotiator preferences. Accordingly, practical negotiation systems should be empowered by effective learning mechanisms to acquire dynamic domain knowledge from the possibly changing negotiation contexts. This article illustrates our adaptive negotiation agents, which are underpinned by robust evolutionary learning mechanisms to deal with complex and dynamic negotiation contexts. Our experimental results show that GA-based adaptive negotiation agents outperform a theoretically optimal negotiation mechanism that guarantees Pareto optimal. Our research work opens the door to the development of practical negotiation systems for real-world applications. &copy; 2006 Wiley Periodicals, Inc. Int J Int Syst 21: 41&ndash;72, 2006.
Small-sample behavior of Weighted Least Squares in experimental design applications
Authors: Jack Kleijnen, Renée Brent, Rien Brouwers
Venue: ACM SIGSIM Simulation Digest (1980)

In experimental design applications unbiased estimators s2i of the variances &sigma;2i are possible. These estimators may be used in Weighted Least Squares (WLS) when estimating the parameters &beta; The resulting small-sample behavior is investigated in a Monte Carlo experiment. This experiment shows that an asymptotically valid covariance formula can be used if s2i is based on, say, at least 5 observations. The WLS estimator based on estimators s2i gives more accurate estimators of &beta;, provided the &sigma;2i differ by a factor, say, 10.

Design of Opportunity Tree Framework for Effective Process Improvement based on Quantitative Project Performance
Authors: Ki-won Song, Kyung-whan Lee
Venue: Proceedings of the Third ACIS Int'l Conference on Software Engineering Research, Management and Applications (2005)

Nowadays IT industry drives to improve the software process on marketing and financial benefits. For efficient process improvement, work performance should be enhanced in line with organization's vision by identifying weakness for improvement and risks with process assessment results and then mapping them in the software development environment. According to organization's vision, plans should be developed for marketing and financial strategic objectives. For each plan, improvement strategies should be developed for each work performance unit such as quality, delivery, cycle time, and waste. Process attributes in each unit should be identified and improvement methods shall be determined for them. In order to suggest a PPM (Project Performing Measure) model to quantitatively measure organization's project performing capability and make an optimal decision for process improvement, this paper statistically analyzes SPICE assessment results of 2,392 weakness for improvement by process for 49 appraisals and 476 processes which were assessed through KASPA(Korea Association of Software Process Assessors) from 1999 to 2004 and then makes SEF(SPICE Experience Factory). It also presents scores on project performing capability and improvement effects by level, and presents weakness for improvement by priority in the performance unit by level. And finally, this paper suggests a OTF(Opportunity Tree Framework) model to show optimal process improvement strategies
Adaptive Neural Network Multiple Models Sliding Mode Control of Robotic Manipulators Using Soft Switching
Authors: Nasser Sadati, Rasoul Ghadami, Mahdi Bagherpour
Venue: Proceedings of the 17th IEEE International Conference on Tools with Artificial Intelligence (2005)

In this paper, an adaptive neural network multiple models sliding mode controller for robotic manipulators is presented. The proposed approach remedies the previous problems met in practical implementation of classical sliding mode controllers. Adaptive single-input single-output (SISO) RBF neural networks are used to calculate each element of the control gain vector; discontinuous part of control signal, in a classical sliding mode controller. By using the multiple models technique the nominal part of the control signal is constructed according to the most appropriate model at different environments. The key feature of this scheme is that prior knowledge of the system uncertainties is not required to guarantee the stability. Also the chattering phenomenon is completely eliminated. Moreover, a theoretical proof of the stability and convergence of the proposed scheme using Lyapunov method is presented. To demonstrate the effectiveness of the proposed approach, a practical situation in robot control is simulated.
On the Implementation of a Low-Power IEEE 802.11a Compliant Viterbi Decoder
Authors: K. Maharatna, A. Troya, M. Krstic, E. Grass
Venue: Proceedings of the 19th International Conference on VLSI Design held jointly with 5th International Conference on Embedded Systems Design (2006)

This article describes a standard cell based novel implementation of a low-power Viterbi Decoder (VD) targeted for the IEEE 802.11a Wireless LAN system. Multiple clock rates have been used to reduce the power consumption and the inherent bandwidth mismatch between the Add-Compare-Select (ACS) and traceback operations. Aggressive clock gating and innovative circuit techniques reduce the power consumption further. The normalized cell area and dynamic power consumption of the designed VD are 5.9 mm² and 53 mW respectively. The normalized power dissipation of the VD is 0.66 mW/Mbps.
Transaction Support Using Unit of Work Modeling in the Context of MDA
Authors: Weerasak Witthawaskul, Ralph Johnson
Venue: Proceedings of the Ninth IEEE International EDOC Enterprise Computing Conference (2005)

Transactions are an important part of most enterprise computing systems. Sometimes they are supported by DBMS and sometimes by transaction monitors. In either case, they are part of the platform used by application developers. A platform independent model of enterprise computing must abstract away transactions and provide platform independent ways of describing them. This paper shows how "unit of work" can be used to support platform independent descriptions of enterprise computing systems that use transactions. Our work is in the context of the OMG's Model Driven Architecture so we provide a UML profile for describing unit of work. We have developed a tool, Mercator, that can translate platform independent models using the unit of work profile to platform dependent models using transactions. When added to our previous work on persistence, this provides a general way of handling transparent transaction management in MDA.
A multidimensional scaling package: MDS(X)
Venue: ACM SIGSOC Bulletin (1976)

Since the advent of multidimensional scaling (MDS) in the early 1960's, there has been a proliferation of computer programs written at many different sites to perform many different MDS analyses employing various models, with widely differing methods of use. In January 1975, under a grant from the Social Science Research Council of the U.K. {the support of the SSRC under Grant numbers HR 3070/1 and HR 4767/1 is gratefully acknowledged}, a project was initiated with the aim of systematizing these programs. The series is known formally as MDS(X), (since all those associated were then at the University of Edinburgh, it is known informally as the Edinburgh series).

Content and Structure Based Approach For XML Similarity
Authors: Yinghua Ma, Richard Chbeir
Venue: Proceedings of the The Fifth International Conference on Computer and Information Technology (2005)

Since the last decade, XML has become inevitable for complex data representation. In this paper, we address a problem of measuring the similarity between XML documents and propose a new XML document similarity approach, which considers the asymmetric similarity and the similarity of both semantic content and document structure. Here, we only consider the measurement of similarity between two XML documents based on the same schema. A prototype has been implemented to validate and evaluate the performances of our proposal. We do believe that our method can also be used to evaluate the similarity of other tree-structured complex data.
Abstraction-basedWorkflow Cooperation Using Petri Net Theory
Authors: Kais Klai, Samir Tata
Venue: Proceedings of the 14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (2005)

The work we present here is in line with a novel approach to inter-organizational workflow cooperation that consists of three steps: workflow advertisement, workflow interconnection, and workflow cooperation. This approach is inspired by the Service-oriented Architecture and allows for partial visibility of workflows. Varying degrees of visibility of workflows enable organizations to retain required levels of privacy and security of internal workflows. Degrees of visibility are described in term of workflow abstraction based on Petri net theory. Abstractions are advertised in a common registry. Workflow interconnections are based on advertised abstraction matching.
Defect Tolerance for Molecular Electronics-Based NanoFabrics Using Built-In Self-Test Procedure
Authors: Mohammad Tehranipoor
Venue: Proceedings of the 20th IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems (2005)

A BIST procedure is proposed for testing and fault tolerance of molecular electronics-based nanoFabrics. The nanoFabrics are assumed to include up to 1010 gates; this requires new test strategies that can efficiently test and diagnose the nanoFabric in a reasonable time. Our BIST procedure utilizes nanoFabric¿s components as test pattern generator and response analyzer. The proposed technique tests the components in parallel with a low number of test configurations reducing the test time significantly. Due to high defect density of nanoFabrics, a diagnostic procedure needs to be done to achieve a high recovery. A defect database is created to be used by compilers during configuring the nanoFabric to avoid defective components. This results in a reliable system constructed using unreliable components.
