New Progression about Gravity Quantization in General Relativity Theory in Real Space-time

Professor Venzo de Sabbata,working at World Laboratory,Lausanne,Switzerland,and Department of Physics,University of Bologna and Ferrara,Italy,is a famous Italy Physicist in the world.He is engaged with a series of creating research works about gravity quantization of General Relativity Theory in the real space-time which attract the attentions of the world.This paper pays the attention to introduce the works of this field,containing mainly:1.quantizing the general relativity theory in the sense of Einstem-Cartan theory,i.e., general relativity adds the torsion,which means introducing spin into the theory of gravity.2. building a compact mathematical tool for research of gravity quantization,the geometric algebra in the real space-time--multivector algebra,i.e.,developing a spinor manifold in the real space-time.     

Comparison between Calibration Procedure and Econometric Estimation

The two methods of estimating parameter in computable general equilibrium(CGE) model are introduced and compared:the calibration procedure and econometric estimation. The conclusions are:the estimation of parameter in CGE model must use the calibration procedure coupled with the econometric estimation method;the elasticity of output with respect to labor input,the marginal expenditure share for households and price elasticity of export demand are estimated by econometric estimation method;and other parameters of the CGE model can be get by calibration procedure.     

Wavelet Edge Detection Method Based-on Multi-scale Fuzzy Logic

A novel edge detection algorithm is proposed by implementing fuzzy image enhancement at different scales.The implement of this algorithm can reduce the negative influence bring from the non-maximum suppression algorithm which select only one threshold.The success of the approach depends on the selection of a general fuzzy operator(GFO) for the enhancement of contrast of region after smoothing of image at different scales.Consequently,it is more obvious that coarse intensity changes are obtained at a large scale whereas the fine details of intensity changes are obtained at a small scale.A pretty performance is obtained by used this work.     

The Method of Diagnosing Brain-dysfunction Based on Membership Function and BP Neural Network

Membership functions.formed with the characteristic values obtained by applying the continuous reaction time (CRT) theory from controls and heptic encephalopthy and proposedin this paper.whith these membership functions,the CRT data to be diagnosed are calculated in advance,and then discriminated by BP meural network to differentiate patients with or without braindysfunction.The troubles of low accuracy and efficiency,encountered in training BP network withfuzzy samples.scattered data and extended samples,are solved.
