c - How to reconnect the clients to server? -

-

my server program (socket stream) running , accepts clients. due abnormal condition, server getting terminated. other side clients waiting server reply. how reconnect running clients new server? functions in sockets?

a socket had been connect()ed once can not reused call connect().

the steps connect tcp server , read/write data follows (pseudo code):

fd = socket(...) // create socket describtor (allocate socket resource) connect(fd, server-address, ...) // connect server read/write(fd, data)  // read server  close(fd) // close /socket descriptor (free socket resource)

in case server goes down after connect client , shall is

close(fd) // close /socket descriptor (free socket resource)

and start on beginning with:

fd = socket(...) // create socket describtor (allocate socket resource) ...

starting on , beginning with:

connect(fd, server-address, ...) // connect server ...

would propably lead undefined behaviour, @ least error.

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.
