Simulating Fuzzy Manufacturing System: Case Study
Authors: A. Azadeh, S. M. Hatefi, H. Kor
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

This paper presents an approach by considering fuzzy parameters in simulation model to obtain fuzzy throughputs in manufacturing systems. The basic subject of simulation is the probabilistic approach to describing real world uncertainty. However, in many cases we do not have information that would be precise enough to build the corresponding probabilistic model or there are some human factors that prevent doing so. In such conditions the statistical and mathematical tools of fuzzy set theory may be successfully used. This paper applies t-test for validating the results obtained from conventional simulation and fuzzy simulation in comparison with the actual data of manufacturing system. Then, we use fuzzy simulation to improve the performance of manufacturing system by considering production constraints, system limitations and desired targets. The design of fuzzy simulation is discussed for an actual and large multi product assembly shop.
NLION: Natural Language Interface for querying ONtologies
Authors: Vivek Anandan Ramachandran, Ilango Krishnamurthi
Venue: Proceedings of the 2nd Bangalore Annual Compute Conference (2009)

Use of semantic web models for representing expert knowledge about a domain as an ontology is becoming increasingly common. However, since these ontologies contain detailed domain information in a formal specification, it cannot be easily understood by a casual user. Providing a natural language interface to ontologies will help such users to retrieve the required information and will further enable use of these ontologies in sophisticated applications. This paper presents NLION, a Natural Language Interface for querying ONtologies, which accepts a natural language query and outputs a SPARQL query. For achieving this, we use semantic relation tagging to recognize the meaning of the user query with respect to the target ontology. NLION effectiveness was analyzed and it was found to be 61.60%.

Enhancing E-health information systems with agent technology
Authors: Minh Tuan Nguyen, Patrik Fuhrer, Jacques Pasquier-Rocha
Venue: International Journal of Telemedicine and Applications (2009)

Agent Technology is an emerging and promising research area in software technology, which increasingly contributes to the development of value-added information systems for large healthcare organizations. Through the MediMAS prototype, resulting from a case study conducted at a local Swiss hospital, this paper aims at presenting the advantages of reinforcing such a complex E-health man-machine information organization with software agents. The latter will work on behalf of human agents, taking care of routine tasks, and thus increasing the speed, the systematic, and ultimately the reliability of the information exchanges. We further claim that the modeling of the software agent layer can be methodically derived from the actual "classical" laboratory organization and practices, as well as seamlessly integrated with the existing information system.
Advanced Planning for Multi-product Across a Supply Chain
Authors: Ruedee Masuchun, Wandee Petchmaneelumka
Venue: Proceedings of the 2009 International Conference on Computer Modeling and Simulation (2009)

This paper presents a linear integer programming model to plan the production for multiple products. The production is planned using information shared across a supply chain. The advantage of information sharing has been proved from research that it can make the whole supply chain globally visualized and yet decreasing in variability on the supply chain. The objective function of the proposed model is to minimize the total costs involved including the production costs, the distribution costs, the setup costs of manufacturing, and the fixed costs of distributing. From previous research, one more restriction which is limitation of distribution centers has been added to make the model more realistic. Numerical results verify that this model can be used to generate feasible and optimal plans for multiple products across the supply chain.
A DSP-based Active Power Filter for Three-phase Power Distribution Systems
Authors: Ping Wei, Zhixiong Zhan, Houquan Chen
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

This paper presents a new digital signal processor (DSP)-based control method for shunt active power filter (SAF) for three-phase power distribution systems. Compared to conventional analog-based methods, the DSP-based solution provides a flexible and cheaper method to control the SAF. The proposed technique requires fewer current sensors than other solutions which require both the source current and the load current information. Furthermore, the proposed technique provides both harmonic elimination and power factor correction. Finally, the simulation and experimental result also shows that both controller techniques can reduce harmonics in three-phase electric systems drawn by nonlinear loads and reduce hardware components.
Pseudospectral method of solution of the Fitzhugh-Nagumo equation
Authors: Daniel Olmos, Bernie D. Shizgal
Venue: Mathematics and Computers in Simulation (2009)

We present a study of the convergence of different numerical schemes in the solution of the Fitzhugh-Nagumo equations in the form of two coupled reaction diffusion equations for activator and inhibitor variables. The diffusion coefficient for the inhibitor is taken to be zero. The Fitzhugh-Nagumo equations, have spatial and temporal dynamics in two different scales and the solutions exhibit shock-like waves. The numerical schemes employed are a Chebyshev multidomain method, a finite difference method and the method developed by Barkley [D. Barkley, A model for fast computer simulation of excitable media, Physica D, 49 (1991) 61-70]. We consider two different models for the local dynamics. We present results for plane wave propagation in one dimension and spiral waves for two dimensions. We use an operator splitting method with the Chebyshev multidomain approach in order to reduce the computational time. Zero flux boundary conditions are imposed on the solutions.
The complexity of clique graph recognition
Authors: Liliana Alcón, Luerbio Faria, Celina M. H. de Figueiredo, Marisa Gutierrez
Venue: Theoretical Computer Science (2009)

A complete set of a graph G is a subset of vertices inducing a complete subgraph. A clique is a maximal complete set. Denote by C(G) the clique family of G. The clique graph of G, denoted by K(G), is the intersection graph of C(G). Say that G is a clique graph if there exists a graph H such that G=K(H). The clique graph recognition problem asks whether a given graph is a clique graph. A sufficient condition was given by Hamelink in 1968, and a characterization was proposed by Roberts and Spencer in 1971. However, the time complexity of the problem of recognizing clique graphs is a long-standing open question. We prove that the clique graph recognition problem is NP-complete.

Authors: Stefanos Vrochidis, Charalampos Doulaverakis, Anastasios Gounaris, Evangelia Nidelkou, Lambros Makris, Ioannis Kompatsiaris
Venue: International Journal of Metadata, Semantics and Ontologies (2008)

This paper introduces a hybrid multimedia retrieval model that is capable of retrieving cultural heritage multimedia content, based on their semantic annotation with the help of an ontology and on low level visual features with a view to finding similar content. The main novelty is the way in which these techniques cooperate transparently during the evaluation of a single query in a hybrid fashion, making recommendations to the user. A search engine has been developed implementing this model, which is capable of searching through cultural heritage multimedia collections, and indicative examples are discussed, along with insights into its performance.
Fashion design styles recommended by consumers' sensibility and emotion
Authors: Youngjoo Na
Venue: Human Factors in Ergonomics Manufacturing (2009)

To develop high-quality and consumer-oriented sensible textiles and fashion designs, a design expert system using the collaborative filtering personalization technique was set up, and its efficiency with the user interface model was examined. A database for 60 textiles, 41 fashion designs, 28 pairs of sensibility words and connection mechanisms, and a 2-D cyber product visualized model with user-manipulating keys was established. It includes feedback of the recommended fashion design that matches the user's sensibility by using visual element adjustment tools provided by the system. Also, through Type III analysis of variance (ANOVA), the most important design category of developing each sensibility on women's dress was found. For the example of contemporary sensibility, the most effective category was skirt length, then sleeve type, color tone, collar type, and the skirt type. All the styles of each category were positioned in 3-D sensibility, using scores of factor analysis from the factors Contemporary, Adult, and Character. The similarity and difference among the fashion style by positioning in 3-D space of sensibility can be visualized. &copy; 2009 Wiley Periodicals, Inc.
Grid metadata management: Requirements and architecture
Authors: Oscar Corcho, Pinar Alper, Paolo Missier, Sean Bechhofer, Carole Goble
Venue: Proceedings of the 8th IEEE/ACM International Conference on Grid Computing (2007)

Metadata annotations of Grid resources can potentially be used for a number of purposes, including accurate resource allocation to jobs, discovery of services, and precise retrieval of information resources. In order to realize this potential on a large scale, various aspects of metadata must be managed. These include uniform and secure access to distributed and independently maintained metadata repositories, as well as management of metadata lifecycle. In this paper we analyze these issues and present a service-oriented architecture for metadata management, called S-OGSA, that addresses them in a systematic way.
A rough set approach for traffic light system with no fixed cycle
Authors: Mayukh Bit, Theresa Beaubouef
Venue: Journal of Computing Sciences in Colleges (2009)

Traffic congestion is one of the leading causes of lost productivity and decreased standard of living in urban areas. The paper applies rough set theory to show the rough relationships between historical and current traffic pattern data and proposes a traffic signal system based on the patterns of historical data. The proposed system does not follow a fixed cycle method which is commonplace in today's traffic light systems. Through the application of probability the system forecasts the traffic loads on lanes and assigns higher credits to a particular one based on the probabilistic values of historical data.

Venue: Proceedings of the 9th International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing (2008)

The paper outlines the necessity of creation of a conceptual model of Scientific Council website. This model could serve as a as a framework for each Scientific Council (SC) website, and as a building block for establishment of SC websites network under the direction of Higher Attestation Commission. Such network would both reinforce the Higher Attestation Commission's leadership role and improve the services offered to the scientific community nationwide. A conceptual model and architecture of SC website are proposed and the process of implementation of a prototype SC website is discussed.
Personalized News Video Recommendation
Authors: Hangzai Luo, Jianping Fan, Daniel A. Keim, Shin'Ichi Satoh
Venue: Proceedings of the 15th International Multimedia Modeling Conference on Advances in Multimedia Modeling (2009)

In this paper, a novel framework is developed to support personalized news video recommendation. First, multi-modal information sources for news videos are seamlessly integrated and synchronized to achieve more reliable news topic detection, and the contexts between different news topics are extracted automatically. Second, topic network and hyperbolic visualization are seamlessly integrated to support interactive navigation and exploration of large-scale collections of news videos at the topic level, so that users can gain deep insights of large-scale collections of news videos at the first glance. In such interactive topic network navigation and exploration process, users' personal background knowledge can be exploited for selecting news topics of interest interactively, building up their mental models of news needs precisely and formulating their queries easily by selecting the visible news topics on the topic network directly. Our system can further recommend the relevant web news, the new search directions, and the most relevant news videos according to their importance and representativeness scores. Our experiments on large-scale collections of news videos have provided very positive results.

Correction of lung boundary using the gradient and intensity distribution
Authors: Yeny Yim, Helen Hong, Joon Beom Seo, Namkug Kim, Eun Jin Chae, Yeong Gil Shin
Venue: Computers in Biology and Medicine (2009)

We propose a new method for correcting the segmented lung boundary in expiratory and inspiratory CT. First, the initial lung boundary is extracted by using density-based segmentation. Second, the scope for the boundary propagation is computed by generating and analyzing the gradient profiles with an adaptive length. The definition of the scope helps to prevent the leakage outside the scope and improves the efficiency of the propagation. Finally, the boundary is propagated within the defined scope using a speed function. The speed function is based on the gradient and intensity distribution and prevents the boundary from converging to the local gradient maxima. The results of the lung boundary correction are evaluated by visual inspections, accuracy evaluations and processing time. Experimental results show that the proposed method corrects the lung boundary reliably and reproducibly.
ECHOES: EduCational Hypermedia On-linE System
Authors: Antonello Pasquarelli, Filippo de Stefani, Gregory M. P. O'Hare, Aidan J. Murphy
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

This paper presents the ECHOES (EduCational Hypermedia On-linE System) training environment, its architecture and the services offered to the users. The main objective of the ECHOES project is to build a distributed dynamic environment for educating and supporting technicians in using and repairing complex industrial artefacts. To pursue this objective, Computer-Web Based Training, Virtual Reality and Multi-Agent Systems are integrated and synthesised in the ECHOES environment. These technologies are used to aid users at different levels of complexity, starting from the novice, who wants to quickly develop a global functional view of complex systems, up to the technician, who needs a strong conceptual understanding of complex equipment. The user interaction with the system is agent based and the chosen interface is the visit metaphor in a 2D or 3D environment, in order to leave the trainee or the technician free in exploring the environment.
Micro-Raman imaging and micro-photoluminescence measurements of strain in ZnMgSe/ZnSe microdiscs
Authors: M. Panfilova, A. Pawlis, C. Arens, S. Michaelis de Vasconcellos, G. Berth, K. P. Hüsch, V. Wiedemeier, A. Zrenner, K. Lischka
Venue: Microelectronics Journal (2009)

Semiconductor microdiscs are promising for applications in photonics and quantum-information processing, such as efficient solid-state-based single-photon emitters. Strain in the multilayer structure of those devices has an important influence on their optical properties. We present measurements of the strain distribution in ZnMgSe/ZnSe microdiscs by means of micro-photoluminescence and micro-Raman imaging. Photoluminescence measurements of microdiscs reveal substantially broadened emission lines with a shift to lower energy at the undercut part of microdiscs, indicating local relaxation in this area. The distribution of the strain in the microdiscs is obtained from an imaging micro-Raman analysis, revealing that the freestanding part of the microdiscs is free of defects.
Automated Synchronous-to-Asynchronous Circuits Conversion: A Survey
Authors: Martin Simlastik, Viera Stopjakova
Venue: Integrated Circuit and System Design. Power and Timing Modeling, Optimization and Simulation: 18th International Workshop, PATMOS 2008, Lisbon, Portugal, September 10-12, 2008. Revised Selected Papers (2009)

Automated synchronous-to-asynchronous circuit conversion can be considered as one area of clockless design style, which is becoming more and more interesting for synchronous designers with lack of knowledge and experience in the real asynchronous circuit design. Another reason why it is becoming so interesting is that the languages and design styles for specification of asynchronous circuits require a learning curve to understand, become proficient with them, and to use them effectively. Hence, numerous approaches for automated conversion of synchronous circuits into their asynchronous counterparts have been proposed in recent years. The main reason is the exploitation of the often claimed advantages of asynchronous circuits, especially their lower power consumption. This paper surveys some of the available well-known synchronous-to-asynchronous conversion techniques and tries to present both their positive and negative properties.
Fur simulation with spring continuum
Authors: Alexis Angelidis, Brendan McCane
Venue: The Visual Computer: International Journal of Computer Graphics (2009)

We propose a practical method for generating and animating fur on parametrized surfaces using a spring continuum. Springs are physically simulated at the vertices of the polygon mesh, and spring behavior is interpolated across the mesh to provide realistic dense fur animation. Our method handles collisions between furry surfaces using a procedural model and self-collisions with a statistical model. The goal of this method is to make it easy for an animator to generate realistic dynamic fur which is efficient to simulate. The technique is most applicable to short fur, rather than long hair.
A neural network-based multi-agent classifier system
Authors: Anas Quteishat, Chee Peng Lim, Jeffrey Tweedale, Lakhmi C. Jain
Venue: Neurocomputing (2009)

In this paper, we propose a neural network (NN)-based multi-agent classifier system (MACS) using the trust, negotiation, and communication (TNC) reasoning model. The main contribution of this work is that a novel trust measurement method, based on the recognition and rejection rates, is proposed. Besides, an auctioning procedure, based on the sealed bid, first price method, is adapted for the negotiation phase. Two agent teams are formed; each consists of three NN learning agents. The first is a fuzzy min-max (FMM) NN agent team and the second is a fuzzy ARTMAP (FAM) NN agent team. Modifications to the FMM and FAM models are also proposed so that they can be used for trust measurement in the TNC model. To assess the effectiveness of the proposed model and the bond (based on trust), five benchmark data sets are tested. The results compare favorably with those from a number of classification methods published in the literature.

Venue: International Symposium on Mobile Ad Hoc Networking Computing (2009)

It is our great pleasure to welcome you to ACM MobiHoc 2009, the 10th ACM International Symposium on Mobile Ad Hoc Networking and Computing. Sponsored by ACM SIGMOBILE, this year's symposium continues its tradition of being the premier international symposium dedicated to addressing challenges emerging from wireless ad hoc networking and computing. With its highly selective technical program, the symposium will bring together researchers and practitioners from a broad spectrum of wireless networking research to present the most up-to-date results and achievements in the field. The call for papers attracted 175 submissions from around the world. Except for a very small number of early rejects, each paper was reviewed by at least three TPC members. After an online discussion phase, the papers which received the most positive scores and comments were presented to the TPC meeting in Chicago on February 7, 2009. At the end of the meeting, the TPC decided to accept 31 papers, resulting in an acceptance rate of 17.7%. The accepted papers form a strong technical program that covers a wide range of topics, including spectrum allocation and management, wireless scheduling, routing and mobility, information dissemination and location service, performance modeling and evaluation, secure communication, sensor coverage and monitoring, and coding and forwarding. In addition, this year's MobiHoc will feature a Best Paper Award, which is selected by a special committee. We hope that the proceedings will serve as a valuable reference for researchers and developers of mobile networks.

Authors: Alex Dekhtyar, Judy Goldsmith, Beth Goldstein, Krol Kevin Mathias, Cynthia Isenhour
Venue: International Journal of Approximate Reasoning (2009)

This paper describes a process by which anthropologists, computer scientists, and social welfare case managers collaborated to build a stochastic model of welfare advising in Kentucky. In the process of collaboration, the research team rethought the Bayesian network model of Markov decision processes and designed a new knowledge elicitation format. We expect that this model will have wide applicability in other domains.
