Aiming at the problem of short transmission distance and low transmission efficiency, a parameter configuration method for the complementary symmetric LCC networks is proposed on the basis of the ECPT system with double-sided LC resonant network. The equivalent capacitance Cs is introduced into LC network to form LCC resonant network. Through the mechanism analysis and the parameter design of the...
In recent years, opinion retrieval attracted a growing research interest as online users' opinions become more and more valuable for market survey, political polls, etc. The goal of opinion retrieval is to find relevant and opinionate documents according to a user's query. Compared with previous lexicon-based generative model for opinion retrieval considering that the sentiment words are equal for...
Agent-based simulation technology is a trend for the future simulation application. This method is more simple and efficient than traditional simulation methods. Agent-based simulation technology with distinct modeling process can greatly reduce the difficulty of modeling and simulation computing, and is more applicable to solve the problems of reliability modeling and simulation for large complex...
The core of future network security protection will be active defence, where security situation prediction plays an important part. In order to solve the problem of uncertainty conversion between qualitative concept and quantitative values in situational awareness, and to improve the degree of matching between data distribution and actual situation, this paper presents a posture prediction algorithm...
Firstly, the limitation of the existing model construction methods is analyzed. Secondly, formal representation of decision problem is given. Thirdly the construction method of decision model based on formalization representation of decision problem is proposed. Then, the model construction process of the method is discussed in detail in terms of description model and problem model.
To make up for the insufficiency of the existing methods of decision model representation in supporting multilevel model users, a kind of hierarchical description framework of decision model is proposed. This framework is made up of basic layer, building block layer and conceptual layer that supporting three kinds of model users, which are the model constructors, the DSS constructors and the decision...
The technology of converting one phase AC to three phase AC should be widely used in electric railway and mountainous area which is out of the way. But the technology has not been solved well for a long time. It is necessary to find a one phase to three phase way to satisfy those occasions which need no-high request and reasonable price. This paper introduces the basic theory of converting one phase...
In this paper, the simulation system of a typical hydroelectric power plant was developed in a MATLAB/Simulink-based software environment, which has a high water head and a long penstock with upstream and downstream surge tanks and is equipped with a Francis turbine. With MATLAB/Simulink, the models of the proposed simulation system are all modularized and visualized, and can be reused easily. No...
