On similarity and inclusion measures between type-2 fuzzy sets with an application to clustering
Authors: Miin-Shen Yang, Der-Chen Lin
Venue: Computers Mathematics with Applications (2009)

In this paper we define similarity and inclusion measures between type-2 fuzzy sets. We then discuss their properties and also consider the relationships between them. Several examples are used to present the calculation of these similarity and inclusion measures between type-2 fuzzy sets. We finally combine the proposed similarity measures with Yang and Shih's [M.S. Yang, H.M. Shih, Cluster analysis based on fuzzy relations, Fuzzy Sets and Systems 120 (2001) 197-212] algorithm as a clustering method for type-2 fuzzy data. These clustering results are compared with Hung and Yang's [W.L. Hung, M.S. Yang, Similarity measures between type-2 fuzzy sets, International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems 12 (2004) 827-841] results. According to different @a-level, these clustering results consist of a better hierarchical tree.

Concept analysis for product line requirements
Authors: Nan Niu, Steve Easterbrook
Venue: Proceedings of the 8th ACM international conference on Aspect-oriented software development (2009)

Traditional methods characterize a software product line's requirements using either functional or quality criteria. This appears to be inadequate to assess modularity, detect interferences, and analyze trade-offs. We take advantage of both symmetric and asymmetric views of aspects, and perform formal concept analysis to examine the functional and quality requirements of an evolving product line. The resulting concept lattice provides a rich notion which allows remarkable insights into the modularity and interactions of requirements. We formulate a number of problems that aspect-oriented product line requirements engineering should address, and present our solutions according to the concept lattice. We describe a case study applying our approach to analyze a mobile game product line's requirements, and review lessons learned.

IT Monoculture Security Risks and Defenses
Authors: Jaynarayan H. Lala, Fred B. Schneider
Venue: IEEE Security and Privacy (2009)

An IT monoculture occurs when a large fraction of the computers in computational ecosystem run the same software. By automatically creating diversity, the risks of deploying an IT monoculture are reduced so that it becomes difficult for a single malware vector to wreck havoc. Two of the articles in this collection discuss techniques to create this diversity; a third article explores the risks of monocultures in the likely context of threats that are known or might be anticipated today.
Restricted Core Stability of Flow Games
Authors: Mao-Cheng Cai, Qizhi Fang
Venue: Proceedings of the 4th International Workshop on Internet and Network Economics (2008)

In this paper, we introduce a kind of restricted core stability for flow games, which is a generalization of the core stability of simple flow games. We first give a characterization on the restricted core, and then propose a sufficient and necessary condition on the restricted core stability for flow games associated with general networks. This condition yields that testing the restricted core stability can be done in polynomial time.

The Helix Grooved Elastomeric Pump
Authors: C. F. Kettleborough, H. Masudi
Venue: Journal of Integrated Design Process Science (2007)

The helix grooved elastomeric pump (HGEP) is a cylindrical viscous screw pump which will pump high viscosity fluids at high pressures and low flow rates. It incorporates an elastomeric O-ring as part of the pumping mechanism. The theory is developed using the smoothed pressure method. Numerical methods are used to develop data for the HGEP performance. Results are presented for a given pump. The results include the effect of film thickness clearances, groove angles, groove depths, and ridge-to-groove width ratios. The aim of the investigation is to provide a theoretical background for the design of an HGEP. The theory is developed for the smoothed pressure formulation and an elastomeric O-ring model is established. The smoothed pressure formulation and the elastomeric O-ring model is set up for numerical solutions; the data obtained show the effects of various film thickness, clearances, groove angles, groove depths, and ridge-to-groove ratios for a given size pump and pumping fluid. The total volumetric flow rate increases with the reduction of the film thickness clearances. The maximum flow rate is obtained with -.0894 mm film thickness clearances. The computer solution is unstable for clearances less than -.0894 mm. The smaller the ridge-to-groove ratio, the performance is better.
Piezoresistive properties of PEDOT: PSS
Authors: Udo Lang, Philipp Rust, Bernd Schoberle, Jurg Dual
Venue: Microelectronic Engineering (2009)

Recent market studies mention the necessity to include sensors in the design of organic electronic devices in order to broaden the range of applications. It is therefore essential to identify potential organic mechanical sensor materials and to develop processes and methods to structure them and characterize their piezoresistive properties. Furthermore, it is also essential for organic electronic devices to know the change of resistance upon bending of flexible substrates. A material widely used in organic electronics is the complex of the intrinsically conductive polymer poly(3,4-ethylenedioxythiophene) and polystyrene sulfonate acid (PEDOT/PSS). In this paper first the fabrication of a polyimide (PI) membrane with integrated PEDOT/PSS strain gauges is presented. Upon a pressure difference the membrane is deflected and the resulting changes in resistance of the sensor elements are recorded. By applying a membrane mechanics model the resistance changes can be linked to the strain in the membrane and then the plane strain gauge factor k"P"S for PEDOT/PSS of 0.48+/-0.07 at 36.6+/-3% rH can be determined.
Teachers' attitudes toward web-based professional development, with relation to Internet self-efficacy and beliefs about web-based learning
Authors: Chia-Pin Kao, Chin-Chung Tsai
Venue: Computers Education (2009)

This study was conducted to explore the relationships between teachers' Internet self-efficacy, beliefs about web-based learning and attitudes toward web-based professional development. The sample of this study included 421 teachers, coming from 20 elementary schools in Taiwan. The three instruments used to assess teachers' Internet self-efficacy (ISS), beliefs about web-based learning (BWL), and attitudes toward web-based professional development (AWPD) revealed high reliability. In this study, the results supported that teachers' Internet self-efficacy and beliefs about web-based learning were important predictors of their attitudes toward web-based professional development. The belief for the positive consequences of web-based learning is very important for the favorable attitudes toward web-based professional development.

Authors: Kathleen Tsoukalas, Bin Zhou, Jian Pei, Davor Cubranic
Venue: Proceedings of the 12th International Conference on Extending Database Technology: Advances in Database Technology (2009)

Given the proliferation of technology sites and the growing diversity of their readership, readers are more and more likely to encounter specialized language and terminology that they may lack the sufficient background to understand. Such sites may lose readership and the experience of readers may be impacted negatively if readers cannot quickly and easily find information about terms they wish to learn more about. We developed a system using a fusion of web log mining techniques that extracts, identifies, and recommends personalized terms to readers by utilizing information found in individual and global web query logs. In addition, the system presents relevant information related to these terms inline with the text. Our system outperforms some other related systems developed in the literature with special regard to usability.

Development of large-scale software is usually conducted through a project to unite a work force. In addition, no matter what kind of life cycle model is employed, a development plan is required for a software development project in order for the united work force to perform effectively. Therefore for the successful project, it is necessary to set management objectives to manage plan, and confirm if they are achieved. This method is considered to be effective, but actually making a software development plan and following-up the achievement of the management objectives at each step is not easy. Because since all the work for software development is done in side of human brain, other people can not measure how much each worker exanimate each work. Therefore it is necessary to secure the time for measuring the depth of a work's examination by project manager's talk with the worker in charge, through automating as many parts as possible by means of mechanizing. It is difficult to make a software development plan itself, because predicting the necessary work amount and risks that the project involves is difficult in software development. Therefore, the authors are developing an automatic schedule planning system for software development so that the project manager can manage the entire project and the work load of the manager is reduced. This paper proposes a method to create automatically such a successful schedule plan that a project, which was behind schedule, will be completed on schedule by means of 'crashing'. And the paper proves that the method is effective in software project management through an example of system.

Personalizing knowledge portals: Principles, requirements, methods
Authors: Eva Oberbichler
Venue:  (2007)

Knowledge has been regarded as an important economic ressource in the past decades; numerous scientists and corporations are therefore engaged in knowledge management. However, corporations still face difficulties in storing and distributing valuable knowledge. Therefore, employees often spend a lot of time searching for relevant knowledge within internal information systems. This book shows how the information overload can be mastered with the help of personalized knowledge portals offering all employees exactly the information they need for their tasks. The author Eva Oberbichler first explains essential tasks of knowledge management and states which of these tasks can be supported by knowledge portals. Subsequently, she deduces requirements of knowledge portals and shows how these requirements, particularly personalization, can be met. In this context, she compares four different personalization methods to facilitate the decision for one of these methods. This book is targeted at corporations wishing to build or personalize a knowledge portal, as well as at economists and business data processing specialists.
Threshold Equalization for On-Line Signature Verification
Authors: Isao Nakanishi, Hiroyuki Sakamoto, Yoshio Itoh, Yutaka Fukui
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

In on-line signature verification, complexity of signature shape can influence the value of the optimal threshold for individual signatures. Writer-dependent threshold selection has been proposed but it requires forgery data. It is not easy to collect such forgery data in practical applications. Therefore, some threshold equalization method using only genuine data is needed. In this letter, we propose three different threshold equalization methods based on the complexity of signature. Their effectiveness is confirmed in experiments using a multi-matcher DWT on-line signature verification system.
Modeling individual animated virtual humans for crowds
Authors: Mustafa Kasap, Nadia Magnenat-Thalmann
Venue: ACM SIGGRAPH ASIA 2008 courses (2008)

We present a real-time individual human body model generation method with commodity graphics hardware. Based on a template body model, per-vertex deformation weights are generated according to the anthropometric measurement standards. These standards are used during the design stage of the template body model to segment it into regions where corresponding measurement parameter and deformation weights are applied to generate individualized model. Existing skinning information is still available regardless of the deformation process, so it is possible to deform the model in any dynamic posture while it is animated. Depending on the anatomical shape of the regions, deformation weights and specific control parameters are blended to change the body sizes on GPU. Calculation of the deformation weights are based on splines and radial distance of the surface vertices. Deformation process preserves the continuity between neighbouring and overlapping regions of the body model. Using a set of high level parameters, this technique could be used to generate different size models in virtual crowds with realtime efficiency.

Authors: Anselm Grundhöfer, Manja Seeger, Ferry Hantsch, Oliver Bimber
Venue: Proceedings of the 2007 6th IEEE and ACM International Symposium on Mixed and Augmented Reality (2007)

In this paper we present an innovative adaptive imperceptible pattern projection technique that takes into account parameters of human visual perception. A coded image is temporally integrated into the projected image, which is invisible to the human eye but can be reconstructed by a synchronized camera. The embedded code is dynamically adjusted on the fly to guarantee its imperceptibility and to adapt it to the current camera pose. Linked with real-time flash keying, for instance, this enables in-shot optical tracking using a dynamic multi-resolution marker technique. A sample prototype has been realized that demonstrates the application of our method in the context of augmentations in television studios.

Authors: Cagatay Catal, Banu Diri
Venue: Information Sciences: an International Journal (2009)

Software quality engineering comprises of several quality assurance activities such as testing, formal verification, inspection, fault tolerance, and software fault prediction. Until now, many researchers developed and validated several fault prediction models by using machine learning and statistical techniques. There have been used different kinds of software metrics and diverse feature reduction techniques in order to improve the models' performance. However, these studies did not investigate the effect of dataset size, metrics set, and feature selection techniques for software fault prediction. This study is focused on the high-performance fault predictors based on machine learning such as Random Forests and the algorithms based on a new computational intelligence approach called Artificial Immune Systems. We used public NASA datasets from the PROMISE repository to make our predictive models repeatable, refutable, and verifiable. The research questions were based on the effects of dataset size, metrics set, and feature selection techniques. In order to answer these questions, there were defined seven test groups. Additionally, nine classifiers were examined for each of the five public NASA datasets. According to this study, Random Forests provides the best prediction performance for large datasets and Naive Bayes is the best prediction algorithm for small datasets in terms of the Area Under Receiver Operating Characteristics Curve (AUC) evaluation parameter. The parallel implementation of Artificial Immune Recognition Systems (AIRS2Parallel) algorithm is the best Artificial Immune Systems paradigm-based algorithm when the method-level metrics are used.

Authors: Klaus Dr&#x00e4;ger, Bernd Finkbeiner, Andreas Podelski
Venue: International Journal on Software Tools for Technology Transfer (STTT) (2009)

In directed model checking, the traversal of the state space is guided by an estimate of the distance from the current state to the nearest error state. This paper presents a distance-preserving abstraction for concurrent systems that allows one to compute an interesting estimate of the error distance without hitting the state explosion problem. Our experiments show a dramatic reduction both in the number of states explored by the model checker and in the total runtime.
Performance of Coherent Receivers for PCTH-Based UWB System with Diversiform Modulation Schemes
Authors: Yun-rui Gong, Di He, Chen He, Ling-ge Jiang
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

The performances of a PCTH-based communication UWB system with diversiform modulation schemes are compared on the classic AWGN channel propagation and the realistic IEEE-UWB channel model. By employing different versions of modulation at the transmitters, the performances of an optimal receiver and a Rake receiver with various combining schemes are studied in this paper. The numerical results for several compared cases illustrate the tradeoff between transmitter diversity and receiver complexity. It is shown that the actual performance of the PAM-PCTH scheme can be better in both kinds of channel propagation. We also find that the PCTH-based UWB system with the Rake receiver has better performance than the conventional proposal for overcoming the multipath propagation effects in the UWB indoor environment.

Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

A novel electronically tunable high input impedance voltage-mode multifunction filter with single inputs and three outputs employing two single-output-operational transconductance amplifiers, one differential difference current conveyor and two capacitors is proposed. The presented filter can be realized the highpass, bandpass and lowpass functions, simultaneously. The input of the filter exhibits high input impedance so that the synthesized filter can be cascaded without additional buffers. The circuit needs no any external resistors and employs two grounded capacitors, which is suitable for integrated circuit implementation.
