php - Code failing to pass query criteria to URL -

-

my problem since added switch function code quering cat_id code can no longer pass query criteria url paginating. cat_id categoryid saved foreign key in child table.

here code if can help:

$criteria = array('ctitle', 'csubject', 'creference', 'cat_id', 'cmaterial', 'ctechnic', 'cartist', 'csource', 'cposture', 'stolen'); $likes = ""; $url_criteria = ''; foreach ( $criteria $criterion ) {         if ( ! empty($_post[$criterion]) ) {                 $value = ($_post[$criterion]);                 $likes .= " , `$criterion` '%$value%'";     switch ($criterion) {                     case 'cat_id':                         $likes .= " , `$criterion`='$value'";                         break;                     default:                         $likes .= " , `$criterion` '%$value%'";                         break;                 $url_criteria .= '&'.$criterion.'='.htmlentities($_post[$criterion]);                 }          } elseif ( ! empty($_get[$criterion]) ) {                 $value = mysql_real_escape_string($_get[$criterion]);                 $likes .= " , `$criterion` '%$value%'";     switch ($criterion) {                     case 'cat_id':                         $likes .= " , `$criterion`='$value'";                         break;                     default:                         $likes .= " , `$criterion` '%$value%'";                         break;                 $url_criteria .= '&'.$criterion.'='.htmlentities($_get[$criterion]);         } //var_dump($likes);         } } $sql = "select * collections c_id>0" . $likes . " order c_id asc"; 

$url_criteria .= '&'.$criterion.'='.htmlentities($_post[$criterion]);

this after 

default:  ... break;

so never executed.

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...
