cmd - Psql script not committing when executed from Java -

-

i have .bat file executes psql command import sql script file. when execute .bat file windows command line, executes correctly. when call .bat file java (with processbuilder), script doesn't end. i'm not getting errors, not in inputstream, errorstream not in db (postgresql) log.

arraylist<string> cmdargs2 = new arraylist<string>();         cmdargs2.add("sql2dbs.bat");           processbuilder pb2 = new processbuilder(cmdargs2);         logger.info(pb2.command().tostring());          map<string, string> env = pb2.environment();         env.put("pgpassword", "user");          process p2 = pb2.start();          bufferedreader stderror2 = new bufferedreader(new inputstreamreader(p2.geterrorstream()));         string s;         while ((s = stderror2.readline()) != null) {             logger.info(s);         }          bufferedreader stdin = new bufferedreader(new inputstreamreader(p2.getinputstream()));         while ((s = stdin.readline()) != null) {             logger.info(s);         }          p2.waitfor();

the sql script long that's why i'm not adding it. script have commit statement @ bottom.

any ideas? thanks,

don't run batch scripts using psql import data database. psql made interactive use, not (ab)used api. can directly in java via jdbc, see instance here or here. using jdbc give far better control , debugging options compared shelling out.

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.
