Abstract: A synthetic fault diagnosis expert system for turbine generator sets based on rule based reasoning and cases based reasoning is built in this paper. The structure of synthetic fault diagnosis expert system is discussed. The rule base and case base for the fault diagnosis of expert system is established based on the domain expert knowledge and relevant fault cases of turbine generator sets. Both the inference flow and case retrieval strategy of diagnosis system are discussed in detail. Finally the expert system is verified by a given application example.

Abstract: This paper reviews the state of development of aviation power and aviation static converter. Considering the urgent need of planes to aviation static converter of high voltage, large current and high power output, this paper mainly studied the DC/DC stage of high voltage dc aviation static converter, and designed the phase shifted ZVS PWM full-bridge converter with two clamping diodes as the basic topological cell of the first stage of the two-stage static converter. Meanwhile the paper analyzed the working principle of the phase shifted ZVS PWM full-bridge converter with two clamping diodes, and then a simulation was run by using the software Saber, which proved theoretical analysis right.

Abstract: During the research of the abnormal flowing of funds, the real financial transaction data warehouse can't be obtained for various reasons. In order to construct the data warehouse needed by this research platform, the paper provides an implementation approach using intelligent Agent software to act for the real roles to solve the problem. From the analysis of the simulation results, the data provided by the simulation method in this paper is feasible.

Abstract: Retracted paper: Galvanic coupling method has been observed to be the best method for data transmission in intra-body communication, which is proposed by Zimmerman in 1995. With the increasing transmission requirements and the development of optical fiber communication, a high speed data transmission system is required and it is possible to design an apparatus to realize the electro optic conversion. In this paper, the characteristics of the intra-body communication system are introduced. Principles and structures of the electro-optic modulation methods for intra-body communication are reviewed. Internal and external modulation methods are introduced and discussed. A system of the electro-optic and acousto-optic modulation are recommended for the intra-body communication system and discussed.

Abstract: In the fast Z-pinch experiments, the beam-target neutrons, the Deuterium-Deuterium neutrons and Deuterium-Tritium neutrons can be generated. It is a good idea to use deuterium Z-pinch plasmas to generate fusion neutrons which can be used in the fusion-fission breeders. The common design of Z-pinch plasmas apparatuses was introduced. The design of Z-pinch apparatuses for fusion-fission breeders is proposed.

Abstract: In this paper, we create the optical differential filter displayed on a digital micromirror device which achieving differential operation of image is proposed. We produced the digital cosine composite grating through the computer which replaced the traditional holographic composite grating filter, and transmitted the image of composite grating to the DMD which connected to the computer. This method can produce optical filters quickly, avoiding developing, fusing processing, and can according to the specific requirements of the image to adjust the filter quickly. The method not only can save time, but also can improve the processing accuracy greatly.

Abstract: This paper describes a method on which modify auxiliary differential equation method by using this method for solving nonlinear partial differential equations and with aid of Maple Software ,we get the exact solution of the generalized schrödinger, including hyperbolic function solutions, trigonometric solution.

Abstract: The auxiliary differential equation method has recently been proposed ,It is introduced to construct more new exact solutions for the variable coefficient KdV equations. As a result , hyperbolic function solutions, trigonometric function solutions, and elliptic function solutions rational function solutions with parameters are obtained.

Abstract: The paper uses soft nuclear CPU as controller created by SOPC, Combins with Ethernet controller components to realize the collection and transmission of multiple rate data.Discusses the characteristic parameterss affect to the CIC and hb filter, and has a optimal design: Demonstrates the best value range of CIC filters order number and extraction ratio, then compensates for bandpass characteristics; hb filter adopts multiphase structure which can improve efficiency.

Abstract: This paper deals with a stochastic model in which claim number follows compound Poisson-Geometric process. By the total expectation formula, renewal equation satisfied by ruin probability has been given, and then, the explicit ruin probability formula is gotten in case of exponential claim amounts.
