Change CSS property on each page using jQuery -

-

i'm trying make navigation menu website. hover event (jquery) changes <div>background position user can see pointing. final effect want achieve looks this:

http://jsfiddle.net/wacku/

the problem solution when click on <li> (page changes) loose variable (background position resets) wonder if there workaround, maybe adding css class element click on (similar wordpress themes)? i'd avoid persisting value cookies.

check current page in window.location.href, , set background image depending on it

var currentpage = window.location.href.split("/").pop(); switch(currentpage){     case "page1.php": $(".topmenu").css('background-position', position1);break;     case "page2.php": $(".topmenu").css('background-position', position2);break;     ... }

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
