Innovations and Advanced Techniques in Computer and Information Sciences and Engineering, 1st edition
Authors: Tarek Sobh
Venue:  (2007)

Innovations and Advanced Techniques in Computer and Information Sciences and Engineering includes a set of rigorously reviewed world-class manuscripts addressing and detailing state-of-the-art research projects in the areas of Computer Science, Computer Engineering and Information Sciences. Innovations and Advanced Techniques in Computer and Information Sciences and Engineering includes selected papers form the conference proceedings of the International Conference on Systems, Computing Sciences and Software Engineering (SCSS 2006) which was part of the International Joint Conferences on Computer, Information and Systems Sciences and Engineering (CISSE 2006). All aspects of the conference were managed on-line; not only the reviewing, submissions and registration processes; but also the actual conference. Conference participants - authors, presenters and attendees - only needed an internet connection and sound available on their computers in order to be able to contribute and participate in this international ground-breaking conference. The on-line structure of this high-quality event allowed academic professionals and industry participants to contribute work and attend world-class technical presentations based on rigorously refereed submissions, live, without the need for investing significant travel funds or time out of the office. Suffice to say that CISSE received submissions from more than 70 countries, for whose researchers, this opportunity presented a much more affordable, dynamic and well-planned event to attend and submit their work to, versus a classic, on-the-ground conference. The CISSE conference audio room provided superb audio even over low speed internet connections, the ability to display PowerPoint presentations, and cross-platform compatibility (the conferencing software runs on Windows, Mac, and any other operating system that supports Java). In addition, the conferencing system allowed for an unlimited number of participants, which in turn granted CISSE the opportunity to allow all participants to attend all presentations, as opposed to limiting the number of available seats for each session.

Adaptive language modeling for word prediction
Authors: Keith Trnka
Venue: Proceedings of the 46th Annual Meeting of the Association for Computational Linguistics on Human Language Technologies: Student Research Workshop (2008)

We present the development and tuning of a topic-adapted language model for word prediction, which improves keystroke savings over a comparable baseline. We outline our plans to develop and integrate style adaptations, building on our experience in topic modeling to dynamically tune the model to both topically and stylistically relevant texts.
A structural computing approach to the production of multimedia document series
Authors: M. Nanard, J. Nanard, J. Chauché, R. R. King
Venue: The New Review of Hypermedia and Multimedia (2006)

The production of multimedia documents of a specified genre from indexed multimedia sources is an important research area. The area adds value to digital library resources and enables the delivery of specific multimedia documents. In this article, we explain how the principles of structural computing may be applied to the production of series of documents complying with some specific genre. The research is inspired by Markov transforms as used in natural language processing. We introduce TTL (Tree Transformation Language), a declarative XML-based formalism for the specification of structural transformation rules. We show, with the aid of a number of examples, how this formalism may be used to specify the narration, rhetoric, and argument structures which respect generic style constraints, and we show how documents are generated. The interpretation of TTL is itself specified as a set of transformation rules, which, together with the SYGMART engine, constitute the SYG-XML environment for producing target documents.
Semantics Driven Development of Software Systems Based on Business Ontologies
Authors: Keiichi Kondo, Shogo Hoshii, Takeshi Morita, Takahira Yamaguchi, Noriaki Izumi, Kôiti Hasida
Venue: Proceeding of the 2006 conference on Knowledge-Based Software Engineering: Proceedings of the Seventh Joint Conference on Knowledge-Based Software Engineering (2006)

For users and developers to form agreements about software system development, we propose a software development method that combines agile software methodologies and knowledge sharing technologies based on business ontologies. These business ontologies enable users and developers to form agreements about system specification by using the ontologies to address three aspects of business application for local governments: legal aspects, business processes, and software design. Our method specifically examines construction of domain models based on business ontologies of the early stage of development to reduce the cost of describing specifications. To recover the completeness of specifications, we propose a Web process architecture, which enables us to transfer a domain model to a design system specification. We have implemented a full environment using JAVA language, which enables us to generate software systems from a set of work processes.
Performance evaluation of a discrete-time Geo[X]/G/1 retrial queue with general retrial times
Authors: Abdel-Karim Aboul-Hassan, Sherif I. Rabia, Fowzia A. Taboly
Venue: Computers Mathematics with Applications (2009)

We consider a discrete-time Geo^[^X^]/G/1 retrial queue with general retrial times. The system state distribution as well as the orbit size and the system size distributions are obtained in terms of their generating functions. These generating functions yield exact expressions for different performance measures. The present model is proved to have a stochastic decomposition law. Hence, a measure of the proximity between the distributions of the system size in the present model and the corresponding one without retrials is derived. A set of numerical results is presented with a focus on the effect of batch arrivals and general retrial times on the system performance. It appears that it is the mean batch size (and not the batch size distribution) that has the main effect on the system performance. Moreover, increasing the mean batch size is shown to have a noticeable effect on the size of the stability region. Finally, geometric retrial times are shown to have an overall better performance compared with two other distributions.
Implementing relationships using Affinity
Authors: Stephen Nelson, David J. Pearce, James Noble
Venue: Proceedings of the Workshop on Relationships and Associations in Object-Oriented Languages (2009)

OO languages typically provide one form of object equality, known as reference equality, where two objects are equal only if they are the same object; two objects which are structurally identical are not considered equal. Thus, programmers who require a more refined notion of equality must define their own operator. Programmer-implemented equality operators tend to rely on informal notions of partial and temporal object immutability which are prone to error. This is a particular problem for objects used in collections which depend on equality. This paper discusses Affinity: an untyped, object-oriented language with a powerful equality operator based on EGAL [2] and support for object-keying and immutability. Affinity is designed to provide coherent and elegant support for object equality, reducing programmer burden and error potential.
Development of a Photo Management System in Schools Which Ensures Students Appear Equally
Authors: Kyoko Umeda, Shinsuke Takito, Tetsuro Ejima, Hironari Nozaki
Venue: Proceeding of the 2006 conference on Learning by Effective Utilization of Technologies: Facilitating Intercultural Understanding (2006)

Japanese elementary and secondary school teachers create class newspapers that include photos of student activities. Japanese teachers have to treat students equally in the class newspaper. Therefore, the teacher usually counts the number of times a student appears in photos. This method does not take into consideration “presence,” the impact of the face in a photo. We developed a photo management system for class newspapers which consider the “equality” of student's appearance of newspaper using objective “presence” metadata that we proposed. The results of the evaluation show that this system can support teachers in selecting photos, or can be used in other institutions where there is a need to manage photos.
Quadrature formulas for Fourier coefficients
Authors: Borislav Bojanov, Guergana Petrova
Venue: Journal of Computational and Applied Mathematics (2009)

We consider quadrature formulas of high degree of precision for the computation of the Fourier coefficients in expansions of functions with respect to a system of orthogonal polynomials. In particular, we show the uniqueness of a multiple node formula for the Fourier-Tchebycheff coefficients given by Micchelli and Sharma and construct new Gaussian formulas for the Fourier coefficients of a function, based on the values of the function and its derivatives.
Weakly connected dominating set-based secure clustering and operation in distributed sensor networks
Authors: Al-Sakib Khan Pathan, Choong Seon Hong
Venue: International Journal of Communication Networks and Distributed Systems (2009)

This paper presents an efficient approach to secure network formation in distributed sensor networks (DSNs), which could be used for secure communications among the nodes after the start of the network's operation. The structure of the network is formed on the basis of offline rank assignments by pre-distribution of secret keys to the participating sensors. Our approach uses the notion of weakly connected dominating set (WCDS) to reduce the number of cluster-heads in the network for greater resource efficiency. The clusters in the network are formed in a secure and efficient way so that no hostile entity could be included in any cluster during network structuring process. We propose an efficient algorithm to form a network-wide secure WCDS, which includes an optional re-keying mechanism to increase the level of security. Our objective is to ensure security in distributed sensor network from the bootstrapping stage up to the beginning of its operation. Along with the description of our approach, we present detailed analysis, simulation results and comparisons of our approach with other related schemes.
A Domain Decomposition Based Parallel Inexact Newton's Method with Subspace Correction for Incompressible Navier-Stokes Equations
Authors: Xiao-Chuan Cai, Xuefeng Li
Venue: Proceedings of the 9th International Conference on Computational Science: Part I (2009)

There are two major types of approaches for solving the incompressible Navier-Stokes equations. One of them is the so-called projection method, in which the velocity field and the pressure field are solved separately. This method is very efficient, but is difficult to be extended to another multi-physics problem when an appropriate splitting is not available. The other approach is the fully coupled method in which the velocity and pressure fields stay together throughout the computation. The coupled approach can be easily extended to other multi-physics problems, but it requires the solution of some rather difficult linear and nonlinear algebraic systems of equations. The paper focuses on a fully coupled domain decomposition based parallel inexact Newton's method with subspace correction for incompressible Navier-Stokes equations at high Reynolds numbers. The discussion is restricted to the velocity-vorticity formulation of the Navier-Stokes equations, but the idea can be generalized to other multi-physics problems.

To Score or Not to Score? Tripling Insights for Participatory Design
Authors: Michael Smuc, Eva Mayr, Tim Lammarsch, Wolfgang Aigner, Silvia Miksch, Johannes Gärtner
Venue: IEEE Computer Graphics and Applications (2009)

For evaluating visual-analytics tools, many studies confine to scoring user insights into data. For participatory design of those tools, we propose a three-level methodology to make more out of users' insights. The Relational Insight Organizer (RIO) helps to understand how insights emerge and build on one each other.
A Visual Analytics Tool for Software Project Structure and Relationships among Classes
Authors: Juan García, Antonio González Torres, Diego Alonso Gómez Aguilar, Roberto Therón, Francisco J. García Peñalvo
Venue: Proceedings of the 10th International Symposium on Smart Graphics (2009)

This paper aims to support the software development and maintenance process with the assistance of a visual analytics tool proposal. The proposal focuses on providing detailed information about the software project structure, class relationships, class coupling, class level metrics and source code. It discloses project structure details and offers interaction techniques in order to quickly review source code classes and obtain insight of their relationships and coupling. The data used in the analysis and visualization has been extracted from Software Configuration Management (SCM) tool repositories. Finally, a case study and the results of applying our tool to several software project revisions are discussed.

Stability and periodicity in dynamic delay equations
Authors: Murat Adıvar, Youssef N. Raffoul
Venue: Computers Mathematics with Applications (2009)

Let T be an arbitrary time scale that is unbounded above. By means of a variation of Lyapunov's method and contraction mapping principle this paper handles asymptotic stability of the zero solution of the completely delayed dynamic equations x^@D(t)=-a(t)x(@d(t))@d^@D(t). Moreover, if T is a periodic time scale, then necessary conditions are given for the existence of a unique periodic solution of the above mentioned equation.
Autonomous Evolutionary Information Systems and Active Database Systems: A Comparative Study
Authors: Jingde Cheng
Venue: Proceeding of the 2008 conference on Knowledge-Based Software Engineering: Proceedings of the Eighth Joint Conference on Knowledge-Based Software Engineering (2008)

Both active database systems and autonomous evolutionary information systems are motivated by improving the passive characteristic of traditional database and/or knowledge-base systems; but they were independently developed until now. To investigate the difference between active database systems and autonomous evolutionary information systems and to find some complementary development methodologies for the both, this paper presents a comparative study of active database systems and autonomous evolutionary information systems. We comparatively discuss motivations, purposes, capabilities, logical foundations of active database systems and autonomous evolutionary information systems. We show that some facilities and their implementation techniques independently developed in active database systems and autonomous evolutionary information systems separately can be complementarily used each other and this will certainly result in progress of the both.
On Partial Deduction and Conversational Agents
Authors: Mariela Morveli-Espinoza, Josep Puyol-Gruart
Venue: Proceeding of the 2008 conference on Artificial Intelligence Research and Development: Proceedings of the 11th International Conference of the Catalan Association for Artificial Intelligence (2008)

Agents are situated autonomous entities that perceive and act in their environment, and communicate with other agents. An agent usually starts a conversation by querying another agent because it needs to satisfy a specific goal. This process allocates a new goal to the agent receiving the initial query, starting new dialogs with other agents, generating a recursive interaction. The generation of this kind of dialog is interesting when the system has the possibility of generating conditional answers with imprecise and uncertain values. We consider simple deliberative rule-based agents that proactively try to satisfy their goals. The mechanism to achieve this dialogs is based in the specialization of the mental state of agents, by means of the partial deduction of rule bases.
Automatic Extraction of Lexical Relations from Analytical Definitions Using a Constraint Grammar
Authors: Olga Acosta
Venue: Proceedings of the 22nd Canadian Conference on Artificial Intelligence: Advances in Artificial Intelligence (2009)

In this paper, we present the preliminary results of a rule-based method for identifying and tagging elements in a hyponymy-hypernymy lexical relation for Spanish. As a starting point, we take into account the role that verbal patterns have in analytical definitions. Such patterns connect each term with its possible genus. We built a constraint grammar based on the results of a syntactic parser. The results demonstrate that constraint grammars provide an efficient mechanism for doing more precise analysis of syntactic structures following a regular pattern.

Flash Lighting Space Sampling
Authors: Matteo Dellepiane, Marco Callieri, Massimiliano Corsini, Paolo Cignoni, Roberto Scopigno
Venue: Proceedings of the 4th International Conference on Computer Vision/Computer Graphics CollaborationTechniques (2009)

Flash light of digital cameras is a very useful way to picture scenes with low quality illumination. Nevertheless, especially low-end cameras integrated flash lights are considered as not reliable for high quality images, due to known artifacts (sharp shadows, highlights, uneven lighting) generated in images. Moreover, a mathematical model of this kind of light seems difficult to create. In this paper we present a color correction space which, given some information about the geometry of the pictured scene, is able to provide a space-dependent correction of each pixel of the image. The correction space can be calculated once in a lifetime using a quite fast acquisition procedure; after 3D spatial calibration, obtained color correction function can be applied to every image where flash is the dominant illuminant. The correction space presents several advantages: it is independent from the kind of light used (provided that it is bound to the camera), it gives the possibly to correct only determinate artifacts (for example color deviation) introduced by flash light, and it has a wide range of possible applications, from image enhancement to material color estimation.
Efficient TCP variant with congestion notification for heterogeneous networks
Authors: K. V. Anusuya, B. Krishna Chaitanya, S. Subha Rani
Venue: International Journal of Communication Networks and Distributed Systems (2009)

In wireless networks, the packet loss may occur due to high bit error rate, packet corruption and link failures. The existing implementations of TCP interpret the loss occurrence is only due to congestion. This erratic prediction reduces the flow rate of TCP segments and it directly degrades its performance. The TCP variants like TCP New Jersey and TCP NJ&#43; achieve improvements in goodput over existing TCP NewReno by distinguishing wireless losses from congestion losses. In this paper, we propose an explicit congestion notification (ECN) enabled negative acknowledgement scheme SNACK-NJ, based on TCP NJ&#43; to further improve the performance of TCP over wireless networks. The simulation results confirm that the proposed scheme outperforms the conventional TCP implementations.
Impact of interchange fees on a nonsaturated multi-agent payment card market
Authors: Biliana Alexandrova-Kabadjova
Venue: International Journal of Intelligent Systems in Accounting and Finance Management (2009)

The impact that the level of interchange fees has on the payment adoption rate in a non-saturated market is investigated. This study is performed under different degrees of consumers' and merchants' awareness of the benefits arriving from the network externalities. In a four-party scheme, we model explicitly the interactions between consumers and merchants at the point of sale. The interchange fees flow from the acquirers to issuers. We allow card issuers to charge consumers with fixed fees and provide net benefits from card usage, whereas acquirers could charge fixed and transactional fees to the merchants. Merchant's transactional fees are determined proportionally to the level of interchange fees. We establish that, under this scheme, the two-sided nature of the market leads to higher adoption rates with lower interchange fees. Copyright &copy; 2009 John Wiley & Sons, Ltd.

Face Recognition Based on Histogram of Modular Gabor Feature and Support Vector Machines
Authors: Xiaodong Li, Shumin Fei, Tao Zhang
Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part III (2009)

In this paper, a novel face recognition algorithm based on histogram of modular Gabor feature and support vector machines is proposed. In this method, each face image is separate into several parts on which Gabor transformation is performed, respectively and then employed 2DPCA for dimensionality reduction. Subsequently, histogram sequences are calculated based on these coefficient features. The final features of face image can be obtained by the fusion of the normalized histogram sequences using weight scheme. Finally, support vector machines is used as classifier. Several experiments on popular face databases such as CAL-PEAL and FERET demonstrate the effectiveness of the proposed method.
