Abstract: Java is a very popular Object-oriented programming (OOP) language because of its platform independent and automatic memory release mechanism (or garbage collection). However, garbage collection also speeds CPU time and should be done after careful consideration. In the paper, memory usage behavior and run-time object characteristics, including heap and object size, object age and access frequency, are studied using several commercial benchmarks. The profiler design method and experiment detail are represented in the paper. The runtime object characteristics are very important to guide the employment of different memory management algorithm.

Abstract: After the emergence of multi-threading technology, which improve the efficiency of the system and improve the running speed of the procedure has played a significant role. While multi-threading has its rare, but not omnipotent, after all, multi-threaded, and it also has many deficiencies. If the programmers simply hold the pursuit of multi-threaded, in the case of improper application, it will reduce the efficiency of procedures, resulting in error that can not be resolved. The paper aims to explain a way to instead of multi-threaded to complete background work: override OnIdle() function of CWinApp class to deal with background tasks. Of course, the function can not be used to complete complex and demanding real-time occasions.

Abstract: Firstly, grid support environment model based on mobile agent is proposed, according to complex sensor applications. Secondly, the prototype scheme of grid support environment was put forward, with division, function, dependant relationship, and disposition of modules given. Finally, the process to develop a grid support environment was introduced. Keywords: mobile agent; smart grid; task mechanism.

Abstract: Traditional software engineering is complex and scalable. The research goal of this paper is to contribute to software engineering discipline via engineering perspective, engineering fundamental principles are studied through the identification of software engineering fundamental principles and the description of operational guidelines. This research also researches the software development lifecycle and the criteria and specifications of software engineering from an engineering perspective.

Abstract: E-Government system based on Multi Source Information Fusion has become a focus of attention. This paper studies the construction method and relevant technology of E-Government system based on Multi Source Information Fusion. A more effective E-government system based on Multi Source Information Fusion can achieve the E-government information resource sharing, and promote intelligent, individualized, one-stop E-Government information service.

Abstract: Power system live working is an important part of power production safety, power system staff training has always been the majority attention of power industry researchers. The 10kV distribution network with high reliability and high security of distribution live working personnel raised taller requirement. In this paper the research and development of 10kV distribution of charged live working simulation training system based on virtual reality technology, it can solve some traditional physical training restrictions, in climate, site, equipment and so on, and has been applied in a number of areas.

Abstract: Core networks should continue delivering best effort service and at the same time they have to be able to meet different transport service requirements initiated by multiplicity of heterogeneous users. Management is a fundamental aspect of the promise of next generation networks and services. In this paper, AutoNet as an autonomic management and control system networks is put forward. AutoNet is architecture to automate data transport delivery in backbone networks. We also take the project of autonomic network control and management system for engineering training room as the instance to research the technology for university experiment teaching.

Abstract: Based on ASP.NET 2.0 framework and ZigBee wireless sensor network, a dynamic management information system for instruments and equipments of experimental centre was designed and developed. Electronic labels were equipped to the object instruments and equipments, and the information was obtained by using ZigBee and Ethernet protocol. The platform of dynamic management was constructed through collecting real-time information of the instruments and equipments in a timely manner. At the university level, the system is coordinated with specified framework of instruments and equipments under the management of State-Owned Assets Department to accept the supervision and inspection by higher level departments. At the college level, it is subdivided to instrument and equipment status (e.g., acquisition/scrap, lent out/returned, running state/using rate, etc.) to realize fast and convenient inquiry about their current inventory status, and their utilization efficiency in the experimental centre is increased to serve students and faculties better.

Abstract: In order to solve the problems of communication and handling datas between IVR system and business system in call center, the middleware is designed. This paper analysises the structure of call center , executing process of the middleware and the function of seat system, IVR and middleware firstly. Then the structure, work flow, key technology of the middleware are descripted in detail, moreover the program of it is designed. Finally, the value and shortcomings of the system are analysised, Practice has proved, this middleware can satisfy the requirements of IVR and seating system data processing.

Abstract: This paper puts forward a method to realize Transact­SQL (T­SQL) automatic test paper evaluation, using one­way close degree to calculate the degree of similarity between the candidate answer and standard answer to realize automatic evaluation. And it introduces the grammar and structure of T­SQL briefly, details the definition of one­way close degree, and analyzes and realizes the one­way close degree algorithm. The comparison of automatic marking and manual marking examples shows that, automatic marking is close to manual marking.
