Real-time u-LBS system for mobile vehicle in 3G networks
Authors: Heemin Kim, Jungwook Song, Miradham Kamilov, Sunyoung Han
Venue: Proceedings of the International Conference on Mobile Technology, Applications, and Systems (2008)

Internet technologies are turning into a fusion of various technologies (architecture, machinery, robotics, traffic, etc). Among these fusion of different technologies, LBS (Location Based Service) is an area where research integrates with every other sectors. The purpose of the LBS system is to provide real-time location information. Such information not only tells the user his own location but also information about the surroundings. This technology and related studies are most commonly dealt with by navigation systems for cars. However, the current LBS service for cars is only service information sent one-way by the server and does not deal with real-time information. However, a problem with the current system is that it does not take full advantage of the LBS system, which is accurate location information, and mobile devices. The goal of this study was to develop an LBS system superior than the current LBS service through actual road tests and to develop a real-time u-LBS system using HSDPA and Wibro Technology of the 3G Network.

Authors: Michal P. Sindlar, Mehdi M. Dastani, Frank Dignum, John-Jules Ch. Meyer
Venue: Declarative Agent Languages and Technologies VI: 6th International Workshop, DALT 2008, Estoril, Portugal, May 12, 2008, Revised Selected and Invited Papers (2008)

In this paper we present mental state abduction, a technique for inferring the mental states (beliefs, goals) of BDI-based agents from observations of their actions. Abduced mental states are considered to be explanations of observed behavior, which is assumed to be part of a (goal-directed) plan. The observer, who attempts to explain an agent's behavior, is assumed to know all of the agent's behavioral rules that can account for observed actions. Three explanatory strategies are introduced, based on different perceptory conditions.
Fundamentals of Business Information Systems
Authors: Ralph M. Stair, George Reynolds
Venue:  (2008)

This new international edition of "Fundamentals of Business Information Systems" continues to offer a concise overview of information systems fundamentals, using the same nine-chapter format as the original US text, but with new content and global examples threaded throughout. Seasoned authors Ralph Stair and George Reynolds are joined by Thomas Chesney (Nottingham University Business School) and together they weave the fundamentals of managing information systems into an understandable and engaging text that is mapped specifically to the requirements of students studying in the United Kingdom, Europe, Middle East and Africa.As with the original United States editions, this text covers the fundamentals of any introductory Management / Business Information Systems (MIS/BIS) course, drawing on material from the new international flagship text, "Principles of Business Information Systems", published contemporaneously. By taking the best material from "Principles of Business Information Systems" and condensing it into nine chapters, this text is particularly suitable for shorter courses or those involving less detail while still requiring a comprehensive survey of the core concepts that make up modern information systems courses.

An Interactive Painting System by Using Enhanced Auto-positioning and Pattern Matching Techniques
Authors: Ling-Erl Cheng, Jiun-Yu Chen, Jar-Ferr Yang
Venue: Proceedings of the 9th Pacific Rim Conference on Multimedia: Advances in Multimedia Information Processing (2008)

In this paper, we propose a low cost interactive painting system, which is realized by a general camera and liquid crystal display (LCD) monitor. By using a newly-designed initialization grid and pattern matching technique, the low-cost camera can achieve a nature painting brush but further figured with many advanced features such video and image capturing, positioning, controlling, painting exiting texture and background capabilities. The proposed interactive painting system can help people to draw a painting directly on any LCD monitor to successfully achieve an edutainment system. Through nature human behaviors, the proposed system can be further advanced to any interactive multimedia educations, gaming and other entertainment applications.
Efficient semantic service discovery in pervasive computing environments

Service-oriented architectures, and notably Web Services, are becoming an incontrovertible paradigm for the development of applications in pervasive computing environments, as they enable publishing and consuming heterogeneous networked software and hardware resources. Combined with Semantic Web technologies, in particular ontologies, Web services' descriptions can be unambiguously and automatically interpreted in open pervasive computing environments, where agreement on a single common syntactic standard for identifying service semantics cannot be assumed. Nevertheless, efficient matching of semantic Web services to effectively automate the discovery and further consumption of networked resources remains an open issue, which is mainly attributable to the costly underlying semantic reasoning. After analyzing the cost of ontology-based semantic reasoning, which is at the heart of the matching process, we propose a solution towards efficient matching of semantic Web services. We have further incorporated our solution into a service discovery protocol aimed at open pervasive computing environments that integrate heterogeneous wireless network technologies (i.e., ad hoc and infrastructure-based networking). Experimental results show that our solution enables better response times than of classical syntactic-based service discovery protocols.
A Detector Generating Algorithm Based on Interval Partition
Authors: Huifen Xia, Shiguang Ju, Tao Cai
Venue: International Journal of Distributed Sensor Networks (2009)

Based on the functions and some relevant theories of the biological immune system, an artificial immune system is established to solve the practical problems for computing systems. At present, the artificial immune system includes two major categories: the mechanism of non-self recognition and immune network, the most important of which is negative selection algorithm. The negative selection algorithm is proposed to simulate the formation and running mechanism of T cells for the immune system in 1994. In this algorithm, one of the key steps is the detector generation. Unfortunately, the current detector generating algorithms have detector generation inefficiencies, holes area, and redundant detector problems to some degree. In this paper, from the perspective of one dimension, a novel detector generating algorithm that is based on interval partition is proposed. At the beginning of this algorithm, we make the maximal interval be the initial detector; second, this detector should experience the training of self-tolerance. According to the matching rule, we let this detector match the given collection of selves; then we remove the points from the interval detector which matches the selves. At the same time, we divide the interval into two parts at this point and have the candidate detectors optimized by the corresponding interval collations and amalgamations. That is to say, the initial detector interval is divided recursively according to the spatial locations of selves. At last, we can get a set of excellent mature detectors, which can be used to protect the system security. To illustrate the advantage of this algorithm, we have given an example. From this example, we can declare that the algorithm improves the current detector generations and matching rules greatly. It also helps to remove the holes area and redundant detectors. Therefore, both the detector generation efficiency and the detecting efficiency are well improved. By the theoretical analysis and comparison, the system can detect a large number of non-self antigens only using a small quantity of detectors. Obviously, the algorithm achieves the high non-self identification system.
On approximating optimum repairs for functional dependency violations
Authors: Solmaz Kolahi, Laks V. S. Lakshmanan
Venue: Proceedings of the 12th International Conference on Database Theory (2009)

We study the problem of repairing an inconsistent database that violates a set of functional dependencies by making the smallest possible value modifications. For an inconsistent database, we define an optimum repair as a database that satisfies the functional dependencies, and minimizes, among all repairs, a distance measure that depends on the number of corrections made in the database and the weights of tuples modified. We show that like other versions of the repair problem, checking the existence of a repair within a certain distance of a database is NP-complete. We also show that finding a constant-factor approximation for the optimum repair for any set of functional dependencies is NP-hard. Furthermore, there is a small constant and a set of functional dependencies, for which finding an approximate solution for the optimum repair within the factor of that constant is also NP-hard. Then we present an approximation algorithm that for a fixed set of functional dependencies and an arbitrary input inconsistent database, produces a repair whose distance to the database is within a constant factor of the optimum repair distance. We finally show how the approximation algorithm can be used in data cleaning using a recent extension to functional dependencies, called conditional functional dependencies.

Authors: Shu-chiao Tsai
Venue: Computers Education (2009)

This study reports on the development of ESP (English for specific purposes) courseware for semiconductor technology and its integration as a ''silent partner'' into instruction. This kind of team-teaching could help overcome current problems encountered in developing ESP in Taiwan. The content of the material under discussion includes general knowledge about fundamental theories, process technologies and applications within the semiconductor industry. In the design of the whole courseware, five skills for learning English (listening, speaking, reading, writing, and translation) have been considered and a 3D multimedia technique has been used to promote learning interest, student engagement, and efficiency. The design of the courseware endeavors to mainly follow principles by [Mayer, R. E. (2001). Multimedia learning. New York: Cambridge University Press]. Students report they have benefited from the courseware implementation. Initial evaluations suggest that students are satisfied with practices for learning professional knowledge and English skills provided by the courseware. They report that the multimedia-assisted environment of the courseware promotes learning effectiveness. Students with higher achievement on the posttest showed better participation and motivation, made greater use of the multimedia and had a better understanding of the English content so that they are more competent to function in a professional and learner-centered ESP course using the courseware.

Fuzzy AHP-based decision support system for selecting ERP systems in textile industry by using balanced scorecard
Authors: Ufuk Cebeci
Venue: Expert Systems with Applications: An International Journal (2009)

An enterprise resource planning system (ERP) is the information backbone of a company that integrates and automates all business operations. It is a critical issue to select the suitable ERP system which meets all the business strategies and the goals of the company. This study presents an approach to select a suitable ERP system for textile industry. Textile companies have some difficulties to implement ERP systems such as variant structure of products, production variety and unqualified human resources. At first, the vision and the strategies of the organization are checked by using balanced scorecard. According to the company's vision, strategies and KPIs, we can prepare a request for proposal. Then ERP packages that do not meet the requirements of the company are eliminated. After strategic management phase, the proposed methodology gives advice before ERP selection. The criteria were determined and then compared according to their importance. The rest ERP system solutions were selected to evaluate. An external evaluation team consisting of ERP consultants was assigned to select one of these solutions according to the predetermined criteria. In this study, the fuzzy analytic hierarchy process, a fuzzy extension of the multi-criteria decision-making technique AHP, was used to compare these ERP system solutions. The methodology was applied for a textile manufacturing company.
CAE (computer aided engineering) driven durability model verification for the automotive structure development
Authors: Dong-Chan Lee, Chang-Soo Han
Venue: Finite Elements in Analysis and Design (2009)

Test/analysis correlation, in the refinement of finite element models to accord with test results of the modeled structure is an emerging field in the today's automotive industries. The accuracy of finite element analysis predictions in the linear and nonlinear specifications becomes more and more important and directly influences the competitiveness of the product. In particular, fatigue or durability is traditionally a test based activity. The drawback with testing is that it can be performed only after the prototype has been built and should design problems surface it would be difficult to redesign, as the design by then is finalized. For this reason, FEA (finite element analysis) based fatigue analysis is increasingly popular and the input loads used for these predictions are derived from test or CAE-predicted virtual prototype. In this point, the well-correlated model is very necessary for the feasible evaluations of structural performances. To perform and process the correlation analysis between durability test and simulation, the FE model updating techniques were developed and implemented into the existing FE software and optimization design. This paper gives a design reference for the durability specifications and model updating techniques.

Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 02 (2009)

The widespread applications of chlorofluorocarbon (CFC) in industry including refrigeration, foam blowing agent and cleaning agent cause severe damage to the ozone layer and might contributed to global warming. Various methods were developed to find CFC alternatives or its environment’s destruction. Among them catalytic conversion of CFCs into valuable compounds like hydrofluorocarbon (HFC) is most promising. It was observed that tungsten carbide (WC) catalyst has high potential in this hydrodehalogenation (HDH) process in remediation of CFCs. To improve reactivity, it is encourage preparing WC catalyst with high surface area. This study however has succeeded in developing high surface area tungsten carbide catalyst for the catalytic HDH of dichlorodifluorocarbon (R-12) using prepared activated carbon from waste palm kernel shell. This prepared catalyst is an economical, alternative route for production of tungsten carbide with high selectivity product towards HFC-32 which has zero ozone depletion potential (ODP).
An automated design approach for CMOS LDO regulators
Authors: Samiran DasGupta, Pradip Mandal
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

This paper presents a method for optimal sizing of CMOS low drop out regulator circuits. The technique relies on the observation that many of the performance metrics of a LDO regulator can be approximated as posynomial functions of design variables. This allows the design problem to be cast as a geometric program. Geometric program is particularly attractive as the tool for optimization as --1)it can be solved very efficiently, 2)it always finds the global minima, 3)infeasible specifications are readily determined and 4)the final solution is completely independent of the initial guess. As a result CMOS LDOs may be conveniently synthesized; moreover the optimal trade off curves between the competing performance metrics, can be obtained very fast.

A new family of sequential elements with built-in soft error tolerance for dual-VDD systems
Authors: Saihua Lin, Huazhong Yang, Rong Luo
Venue: IEEE Transactions on Very Large Scale Integration (VLSI) Systems (2008)

In this paper, we propose some soft-error-tolerant latches and flip-flops that can be used in dual-VDD systems. By utilizing local redundancy and inner feedback techniques, the latches and flip-flops can recover from soft errors caused by cosmic rays and particle strikes. The proposed flip-flop can be used as a level shifter without the problems of static leakage and redundant switching activity. Implemented in a standard 0.18-µm technology, the proposed latches and flip-flops show superior performance compared to conventional ones in terms of delay and power while keeping the soft-error-tolerant characteristic. Experimental results show that compared to the traditional built-in soft-error-tolerant D latch, the D-QN delay of the new D latch is 29.1% less than that of the traditional built-in soft-error-tolerant D latch while consuming 16.5 % less power as well. The D-Q delay and power of the new flip-flop are about 47.7% and 54% less than those of the traditional high speed level-converting flip-flop, respectively. In addition, the proposed flip-flop is more robust to soft errors. The critical charge which represents the minimum charge at the D input required to cause an error of the flip-flop can be increased by more than 46.4 %. The time window during which the flip-flop will be erroneous caused by single-event upsets at the D input is reduced by more than 22.2%.
A local Tchebichef moments-based robust image watermarking
Authors: Cheng Deng, Xinbo Gao, Xuelong Li, Dacheng Tao
Venue: Signal Processing (2009)

Protection against geometric distortions and common image processing operations with blind detection becomes a much challenging task in image watermarking. To achieve this, in this paper we propose a content-based watermarking scheme that combines the invariant feature extraction with watermark embedding by using Tchebichef moments. Harris-Laplace detector is first adopted to extract feature points, and then non-overlapped disks centered at feature points are generated. These disks are invariant to scaling and translation distortions. For each disk, orientation alignment is then performed to achieve rotation invariant. Finally, the watermark is embedded in magnitudes of Tchebichef moments of each disk via dither modulation to realize the robustness to common image processing operations and the blind detection. Thorough simulation results obtained by using the standard benchmark, Stirmark, demonstrate that the proposed method is robust against various geometric distortions as well as common image processing operations and outperforms representative image watermarking schemes.
Toward on-demand wafer fab simulation using formal structure & behavior models
Authors: Edward Huang, Ky Sang Kwon, Leon McGinnis
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Contemporary factories in capital intensive industries such as semiconductor manufacturing are very complex, with many sources of risk. The highly competitive and global business environment forces companies to analyze, design, and continuously re-design factories with distributed multi-disciplinary teams. Traditional factory design approaches using spreadsheets and stand-alone simulations cannot adequately cope with the resulting time, cost, and risk requirements. In this paper, we address the opportunity to support fab design teams by providing on-demand simulation. The method for achieving this combines formal fab descriptive models with a process for generating fab analysis models from relatively standard sources of fab data.
Prototyping digital clay as an active material
Authors: Michael Reed
Venue: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction (2009)

This paper describes a shape input device that extends the behavior of clay as a general model of shape interaction and supports arbitrary material deformation, addition and subtraction at interactive rates. These attributes are implemented in a prototype interface consisting of clay composed of wireless position trackers held together by a binding agent. These trackers provide position data in real time while isosurface extraction reconstructs the surface of the model as the user deforms it. Results are shown of this system behaving as an active material by performing geometry capture, and its utility in an augmented reality environment is discussed.
