Abstract: This paper brings out a new sparse line-optical flow field computing method. Firstly, we establish a lines matching algorithm based on Kalman Filter (KF). In this algorithm, we map lines in an image into Hough space, after that we employ KF to predict the position in the following frame in order to match lines in image sequence. Secondly, we present the concept of sparse line-optical flow field of images and propose the calculation method of it. By using the camera perspective projection model and the optical flow Identity, we can get the sparse line-optical flow field. Simulations is made in the following step, and results show that the lines matching algorithm works well and the accuracy of the calculation method proposed in this paper is as good as that of the classic Horn algorithm, while the calculating time-cost of it is only 1/30 Horn algorithms.

Abstract: Through in-depth understanding of the domain knowledge of insurance and the study of the technology of data warehouse, the paper illustrate the application of data mining technology and data warehouse technology in the insurance clients analysis, and from the basic flow of, discusse the application of data warehouse technology in the field of insurance industry. Then, from the concept of data warehouse, describe the design and implementation of data warehouse concept model and logical model.

Abstract: A lot of domestic and international researches show that the effective management of knowledge has become a powerful way to improve the performance and success in many enterprises. Power concerns a countrys economy and its peoples livelihood so that knowledge management has been widespread concern in the power grid enterprises development and application. On April 29, 2007 , the State Grid Corporation decided to adopt enterprise resource planning (ERP) systems as the core information technology platform and principal means for the informatization construction. In order to improve the efficiency of knowledge dissemination in National Grid ERP and make all the ERP modules theoretical knowledge to be shared, consulted and applied quickly among all he ERP users, this subject was based on the core ideas and characteristics of ERP in Hebei Electric Power Corporation, combined with its use problem of ERP to analyze specifically on the system requirements, functional design, build programs , feasibility and innovation, used ASP.NET and other technologies to achieve the construction of national grid ERP knowledge management system, and provide a knowledge management system (KMS) for quickly accessing, learning and sharing knowledge. It has great practical value.

Abstract: Intelligent transportation system (ITS) is a new informationization, intelligent, and socialization type of modern traffic system. Development of cloud computing technology will bring new space of development for the development Of ITS, and the combination will be the future development trend. The paper discusses the application of cloud computing technology in the field of intelligent traffic, puts forward ITS platform based on cloud computing in order to solve problems that how to share mass traffic information.

Abstract: The Web server delays while selecting course online in college. Adopting JBoss Cache to construct distributed multi-level cache of application server can solve the problem of lack throughput and respond time long effectly.

Abstract: This paper focuses on network management software on the computer a number of issues including the commonly used network management software, network management software applications, user-based network management software, network management software of different characteristics of specific network management software attention to such matters, as well as the development trend.

Abstract: Since CASSANDRA-Iwas successfully produced by Wang Shoujue in 1995, In this paper, we analysis its the learning method of the semiconductor neurocomputer, and apply the semiconductor neurocomputer CASSANDRA-II to face recognition. The satisfactory performance is obtained through experiment results.

Abstract: Network topology is the core of configuration management and the infrastructure of resource management.And it is based on the detection of a network failure and the analysis of network performance.This requires the network topology complete, accurate and friendly interface with visualization.This article describes the classification of the physical network topology discovery.Based on Bridge-MIB and MIB-II of SNMP devices, designed topology discovery algorithm in data link layer and network layer.Test results show that the algorithm can accurately find the device and connection on the network layer and the data link layer.

Abstract: A brief analysis of the current situation of Chinas web accessibility construction. After introducing the relevant experiences of some developed countries, some proposals are discussed to help create user-friendly websites for the visually impaired groups and carry out the barrier-free idea in the web industry.

Abstract: The development of realistic simulation environments is an expensive and time-consuming enterprise. Game Engine is the core component of modern computer games and it provides fundamental functions for games. In this paper, in order to save time and money, game engine is used as platform to develop simulation environment for agents. An Unreal Tournament-Based Simulation Environment (UTSE) for agent simulation is proposed. The reasons for selecting Unreal Engine as the start point of developing our simulation environment are presented. The implementation details of UTSE are also expatiated. And finally, a simple case is given to demonstrate the effectiveness of UTSE to rapidly produce game engine-based high fidelity simulations.
