Grid computing is becoming more and more attractive for coordinating large-scale heterogeneous resource sharing and problem solving. Although Globus toolkit version 4 which is developed based on WSRF can successfully deal with the heterogeneity of resources and the diversity of applications, the current grid environments based on Globus toolkit version 4 have several limitations regarding dynamic reconfiguration of virtual organization (VO) and remote hot deployment of grid services. This paper proposes WIVO (Web-based user Interface for Virtual Organization), the web-based user interface using web service. Using WIVO, user requested sub-VO can easily be configured on top of grid environment based on Globus toolkit version 4, and grid services can also be deployed remotely for better utilization of resources and applications. It is expected that the VO reconfiguration function as well as the remote grid service deployment function provided in WIVO can improve resource and application utilization.
网格计算在协调大规模异构资源共享和问题解决方面越来越具有吸引力。虽然基于WSRF开发的Globus toolkit version 4能够很好地处理资源的异构性和应用程序的多样性，但目前基于Globus toolkit version 4的网格环境在虚拟组织(VO)的动态重构和网格服务的远程热部署等方面存在一定的局限性。本文提出了利用web服务的基于web的用户界面WIVO (web-based user Interface for Virtual Organization)。使用WIVO，可以在基于Globus toolkit version 4的网格环境上轻松配置用户请求的子vo，并且还可以远程部署网格服务，以更好地利用资源和应用程序。期望WIVO提供的VO重构功能和远程网格服务部署功能能够提高资源和应用的利用率。

In this paper, we describe the Gaussian Weighted Histogram Intersection (GWHI) algorithm. The algorithm is able to provide positive results in image retrieval. But the histogram algorithm alters the histogram of an image using particular lighting conditions. Even two images with little differences in lighting are not easily matched. Therefore, we propose that the Histogram Matching Algorithm (HMA) is able to overcome the problem of an image being changed by the intensity or color in the image retrieval. The proposed algorithm is insensitive to changes in the lighting. From the experiment results, the proposed algorithm can achieve up to 30% more recall than the GWHI algorithms, respectively. Also, it can achieve up to 34% more precision than GWHI. Therefore, with our experiments, we are able to show that the proposed algorithm shows limited variation to changes in lighting.

We introduced the motion capture system using two CCD cameras recently, but could not show any better accuracy than a system using PSD camera. In this paper, we propose two kinds of method to improve the accuracy of the 3D acquisition of the motion capture system using CCD cameras. The applied methods are a distortion removal and z-axis adjustment. We show the result how much the accuracy on the 3D acquisition system improved through comparing with the previous system.

Although information technology applications vary widely, they are rarely used in support of creativity. This study presents an idea generation support system based on anchor and gestalt theories. Some perspectives from these theories are borrowed to build theoretical foundation of the proposed system. Anchor building is important to creative process. Applying stimuli suggested by gestalt theory can drive users to generate fresh ideas. The proposed system is domain-independent and can improve personal creativity.

Agent platforms provide a framework for development and execution of parallel applications such as multi-agent based simulation (MABS). However, these platforms have limitations to support large-scale MABS applications in practice. This paper aims at investigating and improving the performance of an agent platform with a MABS workload in distributed environments. We carried out an experimental study with the JADE framework as our agent platform. The experiments show the performance characteristics of the workload and that JADE does not scale well due to message transport and agent directory service limitations. We propose solutions to overcome these performance bottlenecks and facilitate the efficient execution of MABS in a distributed environment. Initial experimental results demonstrate the feasibility of the proposed approaches.

The heterodyne laser interferometer has been widely used in linear displacement and precise measurement field. However the periodic nonlinearity that arises from incomplete laser sources and nonideal optical components restricts the precise measurement at the nano-meter level. In this paper, the total least squares (TLS) algorithm which can obtain optimal compensation parameters of nonlinearity is introduced. Using the TLS algorithm, the nonlinearity error is reduced and the measurement data can be more stabilized. The effectiveness of TLS approach is verified through the comparison of the experimental results with those obtained by a capacitance displacement sensor.

The auto-braking system was designed by VHDL and fabricated to keep a distance. It provides pre-crash safety system for intelligent car. This module can detect the distance between front vehicle and your vehicle to keep a constant distance using a sensor and operate the brake system forcibly if the driver does not decrease the speed of car. The system displays the distance between the two vehicles and the speed of your vehicle. The performance of the system was good.

Spacelog is a continuous collection of existence states and activity experiences of various entities in a physical environment, and it can be regarded as a special database or conceptually seen as a memory organ specifically for a real spatial site such as a home and a laboratory. Different from lifelog that is a personal database for a single individual, the entities in the spacelog cover multiple forms including people, facilities, artifacts, and space-related states in a site. This paper first explains the spacelog concept as compared with concepts of log, lifelog, monitoring cameras and context history, then discusses the fundamental features of the spacelog as well as related technique issues faced to develop spacelog systems, and finally describes the possible novel services and applications using spacelog in smart spaces.
