Published: May 2011

Radar systems are used by air defense forces to detect and track aircraft. Route planning attempts to enhance safety by minimizing the exposure of the aircraft to the threat air defense systems while achieving the mission objectives. Based on Voronoi diagram theory, a flight route optimization method is introduced to insure the armed helicopter to penetrate the emery’s radar defense system at the lowest danger. The factors, such as radar cross section and distance between helicopter and radar, that affect the radar detection are firstly analyzed. Then Voronoi diagram and its application for route planning to minimize the detection probability of an armed helicopter are described introduced in details. Dijkstra algorithm is employed to solve the optimization problem and to obtain the initial flight path. The simulation of artificial potential field dynamic is performed to transform the initial path to the smooth flight route. Example analysis of a hypothesis armed helicopter shows that the developed method is helpful for the on-the-spot planning that combines aircraft flight performance and intelligence information regarding the estimated enemy weapon locations to develop routes that avoid or mask the enemy sensor and weapon envelopes.

Published: May 2011

In this paper, an approach based on wavelet packet analysis is proposed to deal with the problem that acoustic signal of moving vehicle is easily influenced by environmental noise in vehicle type classification. Wavelet packet analysis is applied to extract local and detail feature information of acoustic signal in the time-frequency domain. Firstly, raw acoustic signal is decomposed into different frequency bands by wavelet packet analysis, and then decomposition coefficients are reconstructed. The energy of every frequency band component is used to form the feature vector. Finally, vehicle type classification is implemented by RBF neural network on the basis of these feature vectors. Experimental results show that the proposed method is feasible and effective.

Published: May 2011

Friction force is present in most microelectromechanical systems (MEMS), since they have a large ratio of surface area to their volume. To improve the performance and reliability of MEMS devices, it is necessary to full understand the effect of friction which exists in the majority of MEMS. The model of electrostatic tangential force for MEMS’s moving plates is established based on the rule of energy conservation, further it is revised considering the edge effects by the conformal mapping method for smooth and opening holes plates. Three types of the electrostatic tangential resistance, which are the unrevised theoretical value and revised theoretical value and simulation value, were compared. The effects of microscale and applied voltage and holes are investigated, and the electrostatic tangential resistance between two charged moving plates with respect to each other is analyzed. It is found that the three types of the electrostatic tangential resistance will be increased with the rate of the plate width over the gap of two plates or the applied voltage increasing. And the opening holes did not significantly reduce the value of the electrostatic tangential resistance because of the presence of edge effects. The revised analytic results are larger than the ones not revised, and the former are close to results of ANSYS simulation.

An Empirical Research on the Relationship between Real Estate Prices and Inflation
Authors: Li Tie Qun
Published: May 2011

The former researches referring to inflation and real estate prices concentrated mainly on the stock prices rather than the real estate prices. Owing to the enlarging ratio of real estate industry in national economy with each passing day, as well as the overheating real estate prices in recent years, the relationship between real estate prices and inflation is particularly vital to the monetary policy making for the monetary authorities. According to the test analysis of data from 2001 to 2009, it is found that real estate prices is Granger Cause of inflation while inflation is not the Granger Cause of real estate prices in this paper. Through the Effects of Wealth, Credit and Tobin, real estate prices drive the growth of social consumption and investments and expand the total social demand which possess an positive effect on inflation; nevertheless the rising of real estate prices causes the rising of currency for real estate purchasing, which, under the circumstance of that currency supply remains, will inevitably bring about the reduction of currency for other consumption and investments and restrain the total social demand which would mean a suppression of continuous rising of prices of other commodity and labor service. All these show that real estate also has a negative effect on inflation. The cancellations between the two effects make the long-term influence real estate bearing on inflation is not obvious. The experimental results indicate that when the price of real estate rises 1%, inflation only rises 0.058%. Consequently, a strict controlling of the amount of money issued is the key factor for keeping the over rapid rising of real estate prices from leading to inflation.
On Industrial Cluster Development of Industrial Parks: A Case Study of Jiangxi Province in China
Authors: Liu Xiao Tie
Published: May 2011

This paper analyzes the current development of industry clusters of the industrial parks in Jiangxi. It is found that most of the industrial parks are in the stage of agglomeration, others are in the transitional phase from agglomeration to cluster and the remaining, namely about the one-third industrial parks, are still in the concentrated phase. There is a large gap between the development of the industrial parks in Jiangxi and the requirements of industry clusters, which is embodied in the fact that the industrial structures converge, the growth of industrial chain is incomplete and the supporting system of production is imperfect. Finally, the countermeasures are proposed from the perspective of the government to promote the development of industry clusters of the industrial parks in Jiangxi. These countermeasures mainly are to make the industrial orientation clear, to plan a good industrial layout, to develop the industrial parks based on the mechanism of industriy clusters, to actively explore appropriate development models, to strengthen the construction of industrial supporting system and to create an innovation environment for industry clusters in the industrial parks.

Published: May 2011

The forward displacement analysis of the 6-SPS Stewart mechanism can be transformed into solving complicated nonlinear equations and it is a very difficult process. Taking chaotic sequences as the initial values of damp least square method, all the solutions of equations can be found quickly and making use of existing chaos system and discovering new chaos system to generate chaotic sequences with good properties is the key to the Chaos sequences-based damp least square method. Based on the connection topology of chaotic neural network composed of the four chaotic neurons, hyper-chaos exists in the chaotic neural network system. Combining hyper-chaos with damp least square method, a new method to find all solutions of nonlinear questions was proposed, in which initial points are generated by utilizing hyper-chaotic neural network. Based on direction cosine matrix and Euler parameters, the model of the forward displacements of 6-SPS parallel mechanism with seven variables is built up. The result is verified by a numerical example.
