java - PrintWriter vs FileWriter in the following context -

-

this question has answer here:

what if in next bit of code going substitute (new filewriter (new printwriter

pw = new printwriter(new bufferedwriter(new filewriter  ("xanaduindeed.txt")));  pw = new printwriter(new bufferedwriter(new printwriter ("xanaduindeed.txt")));

both of them work fine, know of 2 optimize memory usage. (if either of 2 better) in advance.

in oracle's jvm:

public printwriter(string filename) throws filenotfoundexception {     this(new bufferedwriter(new outputstreamwriter(new fileoutputstream(filename))),          false); }

printwriter's notable characteristic flush output on every newline (lf or cr or crlf). lowest memory footprint bare filewriter, buffering gives notable improvement in i/o performance.

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

Image
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.
