There is a study in progress that extracts an index using the structure and contents of a document for achieving more effective index extraction and index weighting. Most studies calculate the relevance of the context and determine the index according to the weights of each tag. But, these previous studies are determining the relevance according to simple parameters from general theory, rather than proving relevance via objective experiments. This study classifies a thesis in which the main paragraphs were converted into XML, via XML structural information, and proposes a technique that determines the weight of the final index while updating the weight of the index according to the weight of terms, subsequent to calculating the weight for the term in each paragraph.

Extended Kalman filter (EKF), which has long been used in the field of GPS positioning, has recently been used for indoor positioning, introduced extended Kalman filter (EKF) indoor positioning method based on Bluetooth signal strength. However, the error range of the EKF is so large when it was applied in WLAN tracking that we modified it to use K-NN method for the measurement of the EKF. Furthermore, this paper proposes an idea of improving accuracy of EKF tracking by adjusting parameter values referring to map information. Experimental results comparing our method with other previous methods are discussed.

Events detection is one of the most important issues in data stream processing. Outlier event, change event and burst event are three typical types of event that need to be identified. In this paper, we explore the relationship of these three types of events, and then present a unified framework, named DSED (distributed stream events detection), to handle all of them simultaneously. Rather than collecting all the data in one coordinator node for centralized processing, we also use pre-computing to reduce the communication cost for events detection. Experiment results verify the efficiency of DSED, and also show that our proposed framework can dramatically reduce the communication cost with little false position.

This paper will present the results of a study which included the development of a quality management model, based on an extensive literature survey, and the empirical validation of the model. The study was designed to address two major research questions: 1. What is a plausible model of the quality management process? Specifically, the study aimed to determine which quality management constructs or practices should be included in a model of quality management. Additionally, the study identified or hypothesized a set of relationships among the underlying constructs, and 2. Which of the hypothesized relationships included in the model were supported empirically by real world data? A review of the literature provided the basis for the answers to both parts of question one. A model consisting of eight quality management practices, and five performance measures was developed. The literature review provided support for a proposed set of relationships among the thirteen constructs included in the quality management model. The proposed relationships formed the basis of a set of nine hypotheses tested in the study. A survey instrument was developed, from published indicators, to collect perceptual data about the utilization of quality management practices in companies and the perceived impact of these practices on performance measures. Structural equation modelling was employed to analyze the data collected from two hundred and ninety five respondents at organizations throughout the United States. The resulting model has utility for quality practitioners and researchers since it serves as an organizing framework for understanding the quality management process.

In this paper, we present an image-hiding scheme based on genetic algorithm. The secret messages are embedded into a compressed image of AMBTC. Genetic algorithm is developed to find the best substitution of AMBTC bitmap. The proposed scheme provides high visual quality of the stego-image. The enhanced system of the proposed scheme increases embedding capacity while retaining good quality of the stego-image. Experimental results show that the proposed scheme outperform the comparative schemes.

Investigating inter-organizational cooperation from the perspectives of both partners is important especially when there are interdependencies between the channel partners. The study attempts to accommodate the perspectives of both partners involved in a buyer-supplier relationship and if differences exist between these perspectives, then to understand why these differences exist. The data for this study were collected from buyers responsible for supplier relationships in a Korean telecommunication service provider and from their partners. The results show that switching costs and inter-organizational trust are both significant antecedents of cooperation from the perspective of the buyers, while not significant for the suppliers. Also, the results indicate that technological uncertainty and the fairness of the relationship are significant antecedents from the perspective of the suppliers, and these are not significant for the buyers. In both sample sets, goal consistency significantly affects inter-firm cooperation. The article discusses other findings with important theoretical and practical implications.

In this short paper, we reviewed the possibility of concurrency in a user interface when the client system includes more than one remote service operation. We proposed a concurrency model between server operations, and applied the proposed model to XForms pages. We presented a concurrency control scenario for a Web page.

This paper analyzes the performance of a proposed transmitted-reference (TR) UWB radar system for vehicles. To improve the detection performance of the previous TR-UWB system, the amplitude of a reference pulse can be changed to order to increase the energy-to-noise ratio. Finally, the characteristics of the proposed TR-UWB system are evaluated by simulation. In the AWGN channel, simulation results show that the detection probability of the proposed TR-UWB system with a scaling factor of 2, 10 is an improvement of approximately 3, 6dB, respectively, over the previous TR-UWB system . In the IEEE 802.15.4a Outdoor LOS channel, the detection probability of the proposed TR-UWB system, with a scaling factor of 10, is an improvement over the previous one by approximately 10dB.

In recent years volumes of scientific data and of scientific databases have increased tremendously. Distributing a database across multiple sites is one possible solution to the problem of managing growing data. We address some practical aspects of distributing a large scientific database - the Sloan Digital Sky Survey (SDSS) database. As a preliminary, we also describe how we acquired the SDSS data and set up a mirror site. The architecture of our grid-based distributed database system is presented.

This paper describes preliminary results from using reactive control architecture, known as CAPSC (Control Architecture for Poor Strip Cutting), which is designed for a gas cutting robot in Gwangyang steelworks, South Korea. This gas cutting mobile robot, called APSCR (Autonomous Poor Strip Cutting Robot) is designed to identify the poor strips, move an initial cutting position, and start to cut over 60 m long poor strip every 9 m by using a gas cutting- torch. Since its working environment is extremely complex to robot's functionalities and furthermore robot must deal with explosive tanks, APSCR requires more appropriate control architecture in order to provide the following criterions; safety and simplicity. One of the popular control architectures successfully applied to the service mobile robots, reactive control architecture, is employed as primary control such as navigation, obstacle detection, cutting and so on. Besides, walkthrough procedure for safety is implemented to supervise all possible risks to workers and robot for itself. The experimental results are provided to prove a reliability of the proposed architecture.
