The paper proposes the framework, modules, design and implementation of thesis management system based on specific thesis management mode. The system uses ASP.NET as front development tool, SQL Server 2005 as the background database tool, and based on B/S structure. The system includes these features, teachers submitting topics online, students selecting topics online, exchanges of teachers and students...
The school network as the important infrastructure plays many roles such as school teaching, research, management and foreign exchange, and so on. School network directly affects the security situation in the school's teaching activities. In the early stages of the network, security may not be prominent. With the deeply application, various data online in the school network will increase sharply,...
In order to satisfy the requirements of the government officials of small towns for handling official business on the spot in country area. A small town e-Government system based on Wireless communications technology, Global Positioning System (GPS) technology and Embedded Development Technology was developed. The system can run at the mobile equipments, such as Personal Data Assistant (PDA), intelligent...
This paper implements a PLC(programmable logic controller) based virtual instrument that performs measure and control in mechanical characteristics test for flow control throttle in gas pipeline. The development of the instrument is based on PLC and LabVIEW IDE, which features a novel combination of leading industrial control tools to construct the virtual instrument. Since OPC(OLE for process control)...
The article introduces the structures of Information retrieval system and retrieval process, elaborate the classification of Information retrieval, describe the evaluation index of Information retrieval.
In distributed network, replicas are usually used to elevate data reliability and access efficiency. With the explosion of data quantity and complexity of network environment, the problem of replica consistency maintenance in data-intensive is confronted with challenge. The paper selects replica consistency maintenance in decentralized data centers as subject investigation. Firstly, we introduce the...
This paper is concerned with how to accurately position and find an optimal path through Vehicle Navigation System. This article designed a vehicle dynamic navigation system based on Internet of Things, by using the improved Ant Colony Algorithm. Through computer simulation, we obtained two simulation figures of static navigation route and dynamic navigation route. Besides, the driving directions...

And introduces the DHCP, DNS, Login Scripts, FTP etc design technology, focus on the analysis and research the realization method of key technology of computer graded examination management system based on Windows 2003 Server LAN, And put forward by using cloud computing new technology to improve and improve...
In this paper, we proposed a centralized SIP-based Video Conference System. The function structure of the system was designed and the implementation method was introduced. The proposed Video Conference System can meet to the needs of the application in small medium enterprises, and it can provide higher conference quality with a lower cost.
The rapid increasing of variety and quantity of business brings about serious challenge to the server resources of datacenters. It is difficult for the traditional solution of server running and management to tackle with the changing need of services. The physical server sprawl leads to shortage of computer rack and room space. Meanwhile, the energy consuming increases, so do the difficulty of the...
The domestic platform is composed of the independent and controllable software and hardware equipment, such as CPU, operating system, database and middleware. In order to promote the application of the domestic platform, the simulation verification environment and the integration verification technology are deeply studied in this paper. Firstly, this paper designs the target model of the simulation...
It's the requirement to research data replication strategies for improving the reliability and efficiency of complex network. We use noncooperative game theory to analyze the replica placement problem in the paper, and the model of replica placement in large-scale distributed network is proposed. Then we prove the existence of pure strategy Nash equilibrium in the model, and propose the replica placement...
We present an easy-to-use web server that makes it possible to use a number of known yeast transcription factor binding sites and a novel algorithm for predicting transcription factor binding sites. The 8 kinds of novel evaluating indicators are clearly above the known other 10 algorithms at binding segment level and nucleotide level respectively. The correlation coefficients reach 0.45 and 0.56,...
The Access Grid (AG) is one of the most widely used technologies for building advanced collaborative environment, and a distributed collaborative Augmented Reality (AR) environment has been established with AG and AR technologies. In such distributed shared environment, one of the most difficult tasks is maintaining a consistent view of the shared AR scene among all participants. This paper presents...
