Bi-dimensional Gabor filter with DC component compensation This version of the 2D Gabor filter is basically a bi-dimensional Gaussian function centered at origin (0,0) with variance S modulated by a complex sinusoid with polar frequency (F,W) and phase P described by the following equation: G(x,y,S,F,W,P)=k*Gaussian(x,y,S)*(Sinusoid(x,y,F,W,P)-DC(F,S,P)), where: Gaussian(x,y,S)=exp(-pi*S^2*(x^2+y^2)) Sinusoid(x,y,F,W,P)=exp(j*(2*pi*F*(x*cos(W)+y*sin(W))+P))) DC(F,S,P)=exp(-pi*(F/S)^2+j*P) File Id: 13776 Average rating: 0.0 Size: 1 KB # of reviews: 0 Submitted: 2007-01-26 Downloads: 274 Subscribers: 0 Keywords: gabor filter Stiven Schwanz Dias (Bi-dimensional Gabor filter with DC compo .. compensation This version of the 2D Gabor f ilter is basically a bi-dimensional Gaussian f unction centered at origin (0, 0) with variance S modulated by a complex sinuso id with polar frequency (F, W) and phase P described by the following equati on : G (x, y, S, F, W, P) = k* Gaussian (x, y, S)* (Sinusoid (x, y, F, W, P)- DC (F, S, P)), where : Gaussian (x, y, S) = exp (-pi* S* 2 ^ (x ^ 2 y ^ 2)) Sinusoid (x, y, F, W, P) = exp (j* (2* pi* F* (x* cos (W) y* sin (W)) P))) D C (F, S, P) = exp (-pi* (F/S) ^ 2* P j) File Id : 13776 Average rating : 0.0 Size :# 1 KB of reviews : 0 Submitted : 2007-01-26 Downloads : 274 Subscribers : 0 Keywords : gabor filter Stiven Schwanz Dias)

利用前推回带法计算配电网潮流数据，以一个40节点网络为算例(Push back with the use of the former method to calculate the distribution power flow data, a 40-node network as an example)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

针对现行民用建筑鉴定标准适用于既有公共建筑可靠性鉴定时的内容不足、评价方法保守和评价结果信息量过少的弊端，在原可靠性鉴定规范的基础上综合国内现行规范，建立了包含抗震性能、耐久性、防火性能的既有公共建筑可靠性能评价体系。基于可拓理论将研究对象、评价指标和指标特征结合成物元，通过物元表达式建立了既有公共建筑的可拓评价模型，同时基于MATLAB编制可拓评价程序。(In view of the shortcomings that lack of appraisal contents ,conservative method of evaluation and little information of the evaluation result ,when the existing standard for appraisal of reliability of civil buildings is applied to the reliability evaluation of existing public buildings, the reliability evaluation system of existing public buildings based on existing Standard for appraisal of reliability of civil buildings including seismic performance, durability and fire resistance is established. Based on extension theory research, objects and judging indexes as well as the index characteristic values are considered as matter element. Matter-element model of existing public buildings is established in accordance with the relationship between matter-element. At the same time, the extension evaluation program is compiled based on MATLAB.)

原始lmd算法，效果很不好，不知道程序哪里写错,不太能运行，自己做修改，但是上面的算法比较明确(The original LMD algorithm, the effect is very bad, I don t know where the program is misspelled,but it really can not run.If you want run it,just change a little.Actally the algorithm is clear.)
