The engine excitation control system has significant effect on the static stability, dynamic stability and transient stability of the power system. In power system stability calculation, the model and parameters are used to correct the excitation system. Excitation system parameters are numerous, such...

This article made Computer Simulation Technique to analysis the relationship of the different heights of hit tennis and serve’s effect in the course of tennis serve. The results show that with the increase height of hit tennis the effective area of tennis serve also increased significantly; the success...

Considering the high speed space targets, the real time processing is required with only a few snapshots. Meanwhile, the algorithm based on state space method performs well in the parameter estimation. In this work, we present a novel Direction of Arrival (DOA) estimation based on state space balance...

For plate mill, data communication between Process Control System (PCS) and other system are built with different communication methods. The communication between PCS and Basic Automation system (BAS) is based on the industry Ethernet. Every 200ms, BAS sends actual data to PCS, and PCS sends setup data...

For the purpose of mill Process Control System (PCS) debugging and optimizing, a new simulation method is used. The actual information of rolling process is gathered and sent to the PCS cyclically. This information is saved by PCS. During simulation process, the actual information is read and playback....

For problems in the process of building central air conditioning system to participate in demand response, including non-uniform communication protocol, non-uniform information model and lack of demand response strategy, we put forward the thinking and concrete scheme of research and development of the...

Previous research uses eye blink sensor technology to detect driver's fatigue, which has some limitations in the condition of wearing glasses and lighting changes. To overcome those problems, this paper proposes a way to detect fatigue for drivers through video images and grip forces on steering wheel....

A multi-agent-based cooperative control strategy (MACCS) is proposed for hybrid renewable energy generation system with large-scale wind–photovoltaic energy storage units (WPSUs). The proposed system adopts the negotiation model of the contract net protocol with the non-fixed client–server cooperative...

Coordinated volt/var optimization is fundamental to power dispatch and stability of power system, a novel particle swarm algorithm based multi-agent(MAPSO) is presented. The algorithm combines particle swarm optimization algorithm(PSO) with multi-agent system(MAS). The PSO-MAS utilize an agent as a particle...

With the rapid development of ultra-high voltage grid and interconnections of regional power network, it brings adverse influence on frequency control of the power system. The stability of power grid frequency mainly depends on primary frequency compensation (PFC) and automatic power generation control...

This paper takes the University-enterprise cooperation of the biological science major of Lüliang University as an example. Through the questionnaire survey and interviews with relevant personnel, we can comprehensively investigate the situation of University-enterprise cooperation in Lüliang University....

To investigate the academic status of students and to analyze the trend of students' academic achievement in a new local college of medicine and probes into the key control factors that affect the students' academic failure. Academic cleaning, questionnaire investigation and interview were used to analyze...

According to the state's aim of accelerating the training of high-quality and applied professional degree postgraduates, Henan Polytechnic University and Xu Ji Electric jointly built the Henan Province Graduate Education Innovation Base, the base played an important role in the implementation of the...

In recent years, the rapid progress of urban service industry in our country makes it play a more and more important role in the economic development and modernization of our country. It is an important symbol to measure the socialization of production and the development level of market economy in a...

This paper builds model of multiple industries to analyse contribution of Fujian marine industrial structure change to marine economic growth and apply shift-share analysis method to analyse effect of Fujian marine industrial structure change on marine economic growth. Research results show that the...

The article studied mainly the design of inquiry learning process based on WebQuest and the methods of inquiry teaching activities in the process. Firstly, this paper analyzed the technical advantages of Webquest in cultivating learners' innovation and practical capabilities, and then analyzed the drawbacks...

In recent years, with the acceleration of people's pace of life, the number of chronic diseases in China is increasing. The attention and investment of the country to the medical industry is increasing year by year. At the same time, with the maturity and perfection of data mining technology, many countries...

In this paper, a sliding mode observer (SMO) based on PLL and rotary coordinate is designed for sensorless control of permanent magnet synchronous motors (PMSM). By the proposed SMO algorithm, the control system has a better dynamic performance?And the rotor speed error, the estimated speed, the rotor...

This paper proposes a class of nonlinear stochastic volatility (SV) models based on the Box-Cox transformation. The proposed class encompasses many parametric SV models that have appeared in the literature, including the well known lognormal SV model, and has an advantage in the ease with which different...

For the overheads of 802.11 WLAN, several frame aggregation mechanisms had been proposed to deal with this shortcoming. Since the rare consideration of QoS in these proposals, we took advantage of 802.11e queueing model to enhance the priority scheduling. This paper approaches to eliminate the decomposition...

The feature selection process can be considered a problem of global combinatorial optimization in machine learning, which reduces the number of features, removes irrelevant, noisy and redundant data, and results in acceptable classification accuracy. In this paper, we propose a combination of genetic...

A general phenomenon puzzles all investors is that on one hand, most individual investors believe they need to construct the portfolio consisting of 15 or more stocks to prevent risk because that large investment companies frequently get high returns is due to they obey the existing investment theory...
