java - Timeout for a method -

-

my program looks below

  1. main program (thread 1)
  2. create multiple simple java threads (thead 1.1, 1.2...)
  3. in each thread(1.1 or 1.2..) i'm doing processing calling 1 method not responding(corba calls). want define timer method , thread(1.1 or 1.2 whoever calling) should wait there till response or timer expired.

i have written following sample program. don't think right approach. there better approach? in prg i'm not sure when interupt method invoked.

public class methodtimeout implements runnable{  /**  * @param args  */  public thread t1 = null; public int threadnum = 0; public static void main(string[] args) {       (int i=0; i<3; i++){         methodtimeout mt  =new methodtimeout();         thread t = new thread(mt,"thread "+(i+1));         mt.t1 = t;         mt.threadnum = (i+1);          t.start();     }      system.out.println("stmt after execution"); }  public object testtimeout(){     long starttime = system.currenttimemillis();     try {          system.out.println("in side method start "+t1.getname()+" start time"+starttime);          thread.sleep(5000);     } catch (interruptedexception e) {         // todo auto-generated catch block         e.printstacktrace();     }     long endtime = system.currenttimemillis();     system.out.println("in side method end "+t1.getname()+" total time"+(endtime-starttime) );     return null; }   @override public void run() {      thread timeout  = new thread (){         public void run() {             testtimeout();         };     };     timeout.start();      try {         thread.sleep(2000);         timeout.interrupt();         thread.sleep(2000);     } catch (interruptedexception e) {         // todo auto-generated catch block         e.printstacktrace();     }            system.out.println(t1.getname() + " ending"); }

}

this sounds should implement callable. this example

 import java.util.concurrent.callable;  import java.util.concurrent.executorservice;  import java.util.concurrent.executors;  import java.util.concurrent.future;  import java.util.concurrent.timeunit;  import java.util.concurrent.timeoutexception;   public class test {          public static void main(string[] args) throws exception {          executorservice service = executors.newfixedthreadpool(2);          future<string> futureresult = service.submit(new mycall());              try{                  string result = futureresult.get(20, timeunit.milliseconds);              } catch(timeoutexception timeout){                   system.out.println("timeout");                   service.shutdownnow();              }    }     static class mycall implements callable<string> {         @override         public string call() throws exception {              try{                   //simulate corba work                   thread.sleep(1000);              }catch(interruptedexception e){                   thread.currentthread().interrupt();                   system.out.println("shutting down task!");              }                  return "the result";         }     } }

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.
