java - Getting MD5 checksum on the remote server using JSCH -

-

i writing application requirement transfer files remote sftp server local machine , vice - versa. during file transfer want make sure no data packets lost , corrupted in transit.so idea run md5 checksum on remote file (residing in sftp server) before transfer , start transfer process. once transfer done, run md5 on local file , compare 2 checksums.

i using jsch connect sftp server , code in java.but dont know how run md5 on remote file residing in sftp server.my code has md5 on remote file before transfer takes place.any idea on how accomplish please.

most unix systems have md5sum command. invoke on remote server retrieve hash.

$ md5sum /tmp/test 34a27208f62ff3bdae031c9e8a354ac3  /tmp/test

the jsch website contains an example shows how invoke command on remote server. adapted run md5sum command.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
