Fuzzy Contributive Games: An Extension to the Game of Civic Duty
Authors: Amir Danak, Ashkan Rahimi Kian
Venue: Proceedings of the 17th IEEE International Conference on Tools with Artificial Intelligence (2005)

Game theory deals with decision-making processes involving two or more parties with partly or completely conflicting interests. The players involved in the game usually make their decisions under conditions of risk or uncertainty. In this paper, an idea of nondeterministic payoffs is proposed and optimization is done in a more realistic fuzzy environment, helping each player describe his goal functions by using the linguistic variables. Since fuzzy numbers represent uncertain numeric values, their substitution for traditional crisp payoff values is described and their application is surveyed for a specific sample of contributive games - The game of civic duty. A closed formulation is developed for a vast general class of vague payoffs.
Extraction of Keyterms by Simple Text Mining for Business Information Retrieval
Authors: Xiangzhu Gao, San Murugesan, Bruce Lo
Venue: Proceedings of the IEEE International Conference on e-Business Engineering (2005)

Much of business information is text and the information is subject to frequent changes. The use of efficient and effective mechanisms to retrieve required business information is a key to business success, and automated processing of text to extract keyterms is an essential component of such an information retrieval (IR) system. Traditional text processing methods based on complex linguistic or statistic techniques are not efficient in dealing with frequently changing business information and do not necessarily provide satisfying IR results. We propose a simple method to extract important terms (keyterms) from text for application in different aspects of IR and show through experimentation that its performance is comparable to or better than complex methods.

Authors: Tomas E. Molina, George Yang, Abel W. Lin, Steven T. Peltier, Mark H. Ellisman
Venue: Proceedings of the First International Conference on e-Science and Grid Computing (2005)

Scientific imaging instruments are used in a variety of disciplines to gather vital data for research and study. Specifically, in the biomedical field various types of biological imaging instruments, such as electron microscopes and light microscopes, are used everyday to acquire 2D and 3D datasets for further understanding of biological structures. Remote operation or "tele-operation" of instruments has become a popular solution for research scientists to acquire and share data across research domains separated by geographical barriers. A generalized software architecture solution is presented in this paper to use emerging software technologies to develop a reusable framework to easily integrate instruments for remote-operation in a safe and secure fashion. Web services have emerged as a popular technology to provide software applications with a framework to achieve interoperability and integration with other applications. This generalized software architecture was developed to take advantage of web service middleware technology and to provide a solution for easily plugging in scientific imaging instruments for tele-operation. The architecture has also incorporated Grid technology to achieve a more scalable and robust solution for handling the enormous data sets produced from these instruments. Finally a set of client libraries is presented to demonstrate a useful API for developers to quickly develop a graphical user interface to communicate and acquire data from these instruments.
Computing and applying trust in web-based social networks
Authors: Jennifer Ann Golbeck
Venue:  (2005)

The proliferation of web-based social networks has lead to new innovations in social networking, particularly by allowing users to describe their relationships beyond a basic connection. In this dissertation, I look specifically at trust in web-based social networks, how it can be computed, and how it can be used in applications. I begin with a definition of trust and a description of several properties that affect how it is used in algorithms. This is complemented by a survey of web-based social networks to gain an understanding of their scope, the types of relationship information available, and the current state of trust. The computational problem of trust is to determine how much one person in the network should trust another person to whom they are not connected. I present two sets of algorithms for calculating these trust inferences: one for networks with binary trust ratings, and one for continuous ratings. For each rating scheme, the algorithms are built upon the defined notions of trust. Each is then analyzed theoretically and with respect to simulated and actual trust networks to determine how accurately they calculate the opinions of people in the system. I show that in both rating schemes the algorithms presented can be expected to be quite accurate. These calculations are then put to use in two applications. FilmTrust is a website that combines trust, social networks, and movie ratings and reviews. Trust is used to personalize the website for each user, displaying recommended movie ratings, and ordering reviews by relevance. I show that, in the case where the user's opinion is divergent from the average, the trust-based recommended ratings are more accurate than several other common collaborative filtering techniques. The second application is TrustMail, an email client that uses the trust rating of each sender as a score for the message. Users can then sort messages according to their trust value. I conclude with a description of other applications where trust inferences can be used, and how the lessons from this dissertation can be applied to infer information about relationships in other complex systems.
Database security curriculum in InfoSec program
Authors: S. Srinivasan, Anup Kumar
Venue: Proceedings of the 2nd annual conference on Information security curriculum development (2005)

Database Security course is an important part of the InfoSec curriculum. In many institutions this is not taught as an independent course. Parts of the contents presented in this paper are usually incorporated in other courses such as Network Security. The importance of database security concepts stems from the fact that a compromise of data at rest could expose an organization to a greater security threat than otherwise. Database vulnerabilities exposed recently in several high profile incidents would be a good reason to dedicate a full course to this important topic. In this paper we present key topics such as technologies for database protection, access control, multilevel security, database vulnerabilities and defenses, privacy and legal issues, impact of policies and some well known secure database models.

Document analysis by processing JBIG-encoded images
Authors: E. Regentova, S. Latifi, D. Chen, K. Taghva, D. Yao
Venue: International Journal on Document Analysis and Recognition (2005)

Techniques are presented to directly process JBIG-encoded document images. Two experimental processing pipelines are designed to evaluate the performance of the methods from the application perspective. They are document segmentation for obtaining the global layout and the form processing system for form type identification and the form dropout. The JBIG coding context is employed to perform horizontal smearing and connected-component detection concurrently in the course of decoding the base layer of the JBIG images. It is shown that, using a simple segmentation algorithm, the global layout is identified 50 times faster compared to the case of processing the full resolution images. In addition, an original solution is presented for form type identification by use of the Hough transform of the JBIG base layer images, thus expediting it by a factor of 16 in the designed form dropout system. Advantages of the compressed domain processing include fast procedures, reduced memory requirements, and the possibility of hardware implementation.
Using a Jini based desktop Grid for test vector compaction and a refined economic model
Authors: T. Raja, M. Parashar
Venue: Proceedings of the 2004 IEEE International Symposium on Cluster Computing and the Grid (2004)

Testing of very large scale integrated (VLSI) circuits is done by designing huge random sets of vectors of which only a few are useful. The process of filtering these good vectors from the overall set is called vector compaction. As the integrated circuits become denser, this problem is becoming a major bottleneck and the computation time could run into days for a single chip. In this paper we demonstrate how a distributed Grid architecture can be used for the speed-up of the problem. The architecture is based on a Jini desktop Grid. Economic models become a prime issue in such a scenario. The current economic models for minimizing cost or time are ad-hoc and entirely under the control of the broker middleware architecture, leaving the end user with little choice. In this paper we present a revised economic model that gives more choice to the user in terms of time and cost before execution. We match the high-level application layer to the available resources by utilizing a system of composite performance modeling of the available resources. We demonstrate the performance of this new architecture on some VLSI benchmark circuits.
Modeling a Wearable Full-body Motion Capture System
Authors: Christopher Einsmann, Meghan Quirk, Ben Muzal, Bharath Venkatramani, Thomas Martin, Mark Jones
Venue: Proceedings of the Ninth IEEE International Symposium on Wearable Computers (2005)

This paper describes a feasibility study for a selfcontained, wearable full-body motion capture system based on time-of-flight measurements that provide absolute distances between points on the body. Our motivation for the system is to allow an e-textile garment to sense its own shape using only body-worn sensors, thereby enabling it to dynamically adapt its sensing and processing elements to the user's current pose. Furthermore, a garment that can sense its own shape would enable an untethered and self-contained motion capture system. We explore the potential accuracy of the system via simulation driven by motion data from several users performing various activities, including effects such as the number and placement of sensors on the torso, shadowing of signal transmission by the body, and sensor directionality. We conclude that the system is feasible, albeit with an accuracy that is at least an order of magnitude less than state-of-the-art laboratory systems, and that its accuracy will depend heavily upon the transmission properties of the sensors.
Multipath Load-Balancing Delivery Based on Decisive Energy Ratio in Wireless Sensor Networks
Authors: Yang Zongkai, Yuan Linfeng, Du Xu, Zhang Qifei
Venue: Proceedings of the 11th IEEE International Conference on Embedded and Real-Time Computing Systems and Applications (2005)

Two multipath schemes have been put forward: primary/backup mode and replication mode. Both schemes have not efficiently combined load balancing and energy awareness in sensor networks. This paper proposes an energy-aware load-balancing delivery scheme. The packets can be transmitted along multiple paths according to Decisive Energy Ratio (DER). It needs not calculate DER periodically and brings fewer overheads. DER with Overload Avoidance (DEROA) is also proposed to avoid heavy traffic on some critical nodes. The simulations demonstrate how well DER will achieve multipath delivery.
Numerical Reconstruction of Heat Fluxes
Authors: Jianli Xie, Jun Zou
Venue: SIAM Journal on Numerical Analysis (2005)

This paper studies the reconstruction of heat fluxes on an inner boundary of a heat conductive system when the measurement of temperature in a small subregion near the outer boundary of the physical domain is available. We will first consider two different regularization formulations for this severely ill-posed inverse problem and justify their well-posedness; then we will propose two fully discrete finite element methods to approximate the resultant nonlinear minimization problems. The existence and uniqueness of the discrete minimizers and convergence of the finite element solution are rigorously demonstrated. A conjugate gradient method is formulated to solve the nonlinear finite element optimization problems. Numerical experiments are given to demonstrate the stability and effectiveness of the proposed reconstruction methods.
A Fast Linkage Detection Scheme for Multi-Source Information Integration
Authors: Akiko Aizawa, Keizo Oyama
Venue: Proceedings of the International Workshop on Challenges in Web Information Retrieval and Integration (2005)

Record linkage refers to techniques for identifying records associated with the same real-world entities. Record linkage is not only crucial in integrating multi-source databases that have been generated independently, but is also considered to be one of the key issues in integrating heterogeneous Web resources. However, when targeting large-scale data, the cost of enumerating all the possible linkages often becomes impracticably high. Based on this background, this paper proposes a fast and efficient method for linkage detection. The features of the proposed approach are: first, it exploits a suffix array structure that enables linkage detection using variable length n-grams. Second, it dynamically generates blocks of possibly associated records using 'blocking keys' extracted from already known reliable linkages. The results from our preliminary experiments where the proposed method was applied to the integration of four bibliographic databases, which scale up to more than 10 million records, are also reported in the paper.
Implementing a modular access control service to support application-specific policies in CaesarJ
Authors: Tine Verhanneman, Frank Piessens, Bart De Win, Eddy Truyen, Wouter Joosen
Venue: Proceedings of the 1st workshop on Aspect oriented middleware development (2005)

Ideally, the enforcement of application-specific policies in an access control service should be untangled from the application logic. The access control services that are provided in state-of-the-art application servers typically fail to support such a separation. Aspect-Oriented Software Development techniques can be used to alleviate such shortcomings. This paper describes the design and implementation of a modular access control service that improves the separation between application logic and access control. The prototype has been implemented in CaesarJ.
A Prediction-Based Approach to Concurrency Control Resulting in Low Blocking Rate under High-Quality Mobile Environment
Authors: Li Xiao-rong, Shi Bai-le
Venue: Proceedings of the The Fifth International Conference on Computer and Information Technology (2005)

Mobile transaction management, even in a high quality networks nowadays, possesses some intrinsic characterestics, such as high blocking rate and high probability of thrashing caused by the instability of bandwidth and mobility of users. ASGT (Active Serialization Graph Technique), a new scheme developed accordingly, brings about a very low blocking rate and can abort predicted transactions involved in non-serializable scheduling. In addition, ASGT is adaptive to be integrated with an aborting method, called MWDL, to improve the performance and to reduce the scheduling cost.
Transpost: A Novel Approach to the Display and Transmission of 360 Degrees-Viewable 3D Solid Images
Authors: Rieko Otsuka, Takeshi Hoshino, Youichi Horry
Venue: IEEE Transactions on Visualization and Computer Graphics (2006)

Three-dimensional displays are drawing attention as next-generation devices. Some techniques which can reproduce three-dimensional images prepared in advance have already been developed. However, technology for the transmission of 3D moving pictures in real-time is yet to be achieved. In this paper, we present a novel method for 360-degrees viewable 3D displays and the Transpost system in which we implement the method. The basic concept of our system is to project multiple images of the object, taken from different angles, onto a spinning screen. The key to the method is projection of the images onto a directionally reflective screen with a limited viewing angle. The images are reconstructed to give the viewer a three-dimensional image of the object displayed on the screen. The display system can present images of computer-graphics pictures, live pictures, and movies. Furthermore, the reverse optical process of that in the display system can be used to record images of the subject from multiple directions. The images can then be transmitted to the display in real-time. We have developed prototypes of a 3D display and a 3D human-image transmission system. Our preliminary working prototypes demonstrate new possibilities of expression and forms of communication.
Some test results on the SIMSCRIPT II. 5 and SIMPL/1 pseudorandom number generators
Authors: George S. Fishman
Venue: ACM SIGSIM Simulation Digest (1976)

This paper presents results of applying the runs up and down test, the chi-square goodness-of-fit test and the serial test to streams of pseudo-random number generators implemented in the IBM version of SIMSCRIPT II.5, in SIMPL/1 and using their default seeds. Although this limited testing prevents general conclusions, the results presented here do identify several areas of concern. Because of the limited publication of such test information in the learned literature, it is regrettably not possible to offer a completely acceptable method of removing these concerns.
Questions For The Dynamicist: The Use of Dynamical Systems Theory in the Philosophy of Cognition
Authors: Marco Van Leeuwen
Venue: Minds and Machines (2005)

The concepts and powerful mathematical tools of Dynamical Systems Theory (DST) yield illuminating methods of studying cognitive processes, and are even claimed by some to enable us to bridge the notorious explanatory gap separating mind and matter. This article includes an analysis of some of the conceptual and empirical progress Dynamical Systems Theory is claimed to accomodate. While sympathetic to the dynamicist program in principle, this article will attempt to formulate a series of problems the proponents of the approach in question will need to face if they wish to prolong their optimism. The main points to be addressed involve the reductive tendencies inherent in Dynamical Systems Theory, its somewhat muddled position relative to connectionism, the metaphorical nature DST-C exhibits which hinders its explanatory potential, and DST-C's problematic account of causality. Brief discussions of the mathematical and philosophical backgrounds of DST, seminal experimental work and possible adaptations of the theory or alternative suggestions (dynamicist connectionism, neurophenomenology, R D theory) are included.
Functional distribution of the workload of a linked computer system and its simulation
Authors: Constantine Lazos
Venue: ACM SIGSIM Simulation Digest (1977)

Consideration is given to a possible functional distribution of the workload over two linked computers with separate channel access to a large disc store, into the resource utilisation of the linked system achieved by simulation using a modified and re-entrant single processor simulator. Results suggest that the proposed distribution realises a high utilisation.
A Characterization of the Complement of a Hyperbolic Quadric in PG (3, q), for q Odd
Authors: Sara Cauchie
Venue: Designs, Codes and Cryptography (2006)

The incidence structure NQ+(3, q) has points the points not on a non-degenerate hyperbolic quadric Q+(3, q) in PG(3, q), and its lines are the lines of PG(3, q) not containing a point of Q+(3, q). It is easy to show that NQ+(3, q) is a partial linear space of order (q, q(q¿1)/2). If q is odd, then moreover NQ+(3, q) satisfies the property that for each non-incident point line pair (x,L), there are either (q¿1)/2 or (q+1)/2 points incident with L that are collinear with x. A partial linear space of order (s, t) satisfying this property is called a ((q¿1)/2,(q+1)/2)-geometry. In this paper, we will prove the following characterization of NQ+(3,q). Let S be a ((q¿1)/2,(q+1)/2)-geometry fully embedded in PG(n, q), for q odd and q>3. Then S = NQ+(3, q).
Classifier Fusion Using Shared Sampling Distribution for Boosting
Authors: Costin Barbu, Raja Iqbal, Jing Peng
Venue: Proceedings of the Fifth IEEE International Conference on Data Mining (2005)

We present a new framework for classifier fusion that uses a shared sampling distribution for obtaining a weighted classifier ensemble. The weight update process is self regularizing as subsequent classifiers trained on the disjoint views rectify the bias introduced by any classifier in preceding iterations. We provide theoretical guarantees that our approach indeed provides results which are better than the case when boosting is performed separately on different views. The results are shown to outperform other classifier fusion strategies on a well known texture image database.

Authors: J. Mitard, C. Leroux, G. Ghibaudo, G. Reimbold, X. Garros, B. Guillaumot, F. Boulanger
Venue: Microelectronic Engineering (2005)

In this contribution, the kinetics of the trapping/detrapping process involved in hysteresis phenomena of HfO2 films have been investigated on a large temperature range, from 20K to 500K range. Using an appropriate methodology, charge trapping and detrapping are shown, for the first time, to be temperature independent when they are corrected for the threshold voltage variation with temperature. This result evidenced here, strongly suggests that analysis of trapping and detrapping mechanisms must be compared at same dielectric field. Moreover, it confirms the importance of the direct tunneling mechanism especially Shockley-Read-Hall process for all operational conditions.
