This paper proposes a real-time data compression and adapted protocol technique for wide-area measurement systems (WAMS). The compression algorithm combines exception compression (EC) with swing door trending (SDT) compression. The compression logic is designed to perform this algorithm in real time. Selection of compression parameters and data reconstruction are presented. An adapted protocol is...
Three kinds of air-cooling systems and their technical features have been described in this paper. Combined with the energy policy in our country, the perspective of air-cooling unit is discussed mainly in terms of coal-fired unit applied status, air-cooling unit's development and our country's energy policy etc. And the matters needing attention and the needed taken measures in the conscientions...
With the development of the computer technology, the computer examination system has been used in many examinations. This article first introduces the goals and tasks for the development of the computer examination system, followed by the introduction of the functions of the system which is based on genetic algorithm, and finally describes the implementation of the computer examination system.
Nowadays, it is very common that commercial banks outsource their call centers in order to reduce their operational cost so that they can better focus on their core business operation and management. However, before doing that, there should be an appropriate system to evaluate the customer satisfaction degree in call center so that top management can supervise its performance. In the evaluation system,...
The decarburization predication model was used to detection of carbon content in RH degasser. Decarburization predication system in RH degasser uses computer technology to analyze on-line data, to study the relation between the carbon content and the difference type molten steel data and processing data and to recognize carbon content of the steel with expert knowledge. The recognizing results can...
In order to teach college freshmen more conveniently, we have formulated a questionnaire to investigate the computer basic knowledge they had got in secondary schools. This paper measures and analyzes the reliability and validity of that questionnaire by the technology of education measurement. The result indicates that the questionnaire has a good internal consistency; and its distinction validity,...
CDIO is a new mode in modern engineering education distinguished from traditional modes, which is project-based. CDIO stands for conceiving, designing, implementing and operating. It has been proved effective in engineering education. After the steps of CDIO analyzed, an example using CDIO is presented to show how CDIO works, and how traditional courses are changed into CDIO courses as well. The experiments...
To realize the dynamic testing method & collecting sampling data in process of fields in industry is a problem solving in all the time. This paper gives a novel automation dynamic testing method based AI-Controlling of VCR, it is with some advantages that as follows: 1)An excellent effectiveness for a given period of time; 2)An integrated controlling area without any spots as yet untouched by...
The paper affirms a modern important method of education in networks, it is thought highly of all governments & society in the world day by day. It points that, universities in networks are some enlargement/extension of the traditional universitiespsila function, the dynamic education resources in networks are urgent need of plenty, constructing of educated information networks stations are urgent...
P3P is an industry standard method that enables users to gain powerful control over their processing of personal information on Web sites being visited. Traditional methods of database access control places great dependence on the use application of statically defined views. In this paper, we propose the procedure by which current RDBMS can be transformed into their privacy-preserving equivalents...
