jQuery Isotope Combination Filters with BBQ Hash History - Highlight filter options when stepping through history -

-

i have page using excellent isotope , bbq jquery plugins. have followed combo filters , has history demo/test amongst other things, cannot figure out how filters select when stepping through page history (as seen on regular hash history demo).

here's complete js code:

    // modified isotope methods gutters in masonry $.isotope.prototype._getmasonryguttercolumns = function() {     var gutter = this.options.masonry && this.options.masonry.gutterwidth || 0;         containerwidth = this.element.width();      this.masonry.columnwidth = this.options.masonry && this.options.masonry.columnwidth ||                   // or use size of first item                   this.$filteredatoms.outerwidth(true) ||                   // if there's no items, use size of container                   containerwidth;      this.masonry.columnwidth += gutter;      this.masonry.cols = math.floor( ( containerwidth + gutter ) / this.masonry.columnwidth );     this.masonry.cols = math.max( this.masonry.cols, 1 ); };  $.isotope.prototype._masonryreset = function() {     // layout-specific props     this.masonry = {};     // fixme shouldn't have call again     this._getmasonryguttercolumns();     var = this.masonry.cols;     this.masonry.colys = [];     while (i--) {       this.masonry.colys.push( 0 );     } };  $.isotope.prototype._masonryresizechanged = function() {     var prevsegments = this.masonry.cols;     // update cols/rows     this._getmasonryguttercolumns();     // return if updated cols/rows not equal previous     return ( this.masonry.cols !== prevsegments ); };  $(function(){     var wait = $(".loading");     wait.animate({opacity: 0}, 500, 'linear').animate({opacity: 1}, 500, 'linear');      var $container = $('#container');     var initialoptions = {         filter: '*',         itemselector : '.item',         sortby: 'random',         layoutmode: 'masonry',         masonry: {             columnwidth: 170,             gutterwidth: 6.6         }     };      $container.imagesloaded( function(){          // build hash our options         var options = {             // special hash combination filters             combofilters: {}         };          var $optionsets = $('#options').find('.option-set'),             isoptionlinkclicked = false;          // filter buttons         $optionsets.find('a').click(function(){         //$('.filter').on( 'click', 'a', function( event ) {             event.preventdefault();             var $this = $(this);             // don't proceed if selected             if ( $this.hasclass('selected') ) {               return false;             }              selectlink( $this );              var $optionset = $this.parents('.option-set');             var group = $optionset.attr('data-filter-group');             options.combofilters[ group ] = $this.attr('data-filter-value');             $.bbq.pushstate( options );             isoptionlinkclicked = true;         });          function selectlink( $link ) {             $link.parents('.option-set').f  ind('.selected').removeclass('selected');             $link.addclass('selected')         }          var location = window.location;         var $combofilteroptionsets = $('.combo-filters .option-set');         var hashchanged = false;          function getcombofilterselector( combofilters ) {             // build filter             var isofilters = [];             var filtervalue, $link, $optionset;             ( var prop in combofilters ) {                 filtervalue = combofilters[ prop ];                 isofilters.push( filtervalue );                 // change selected combo filter link                 $optionset = $combofilteroptionsets.filter('[data-filter-group="' + prop + '"]');                 $link = $optionset.find('a[data-filter-value="' + filtervalue + '"]');                 //selectlink( $link );             }             var selector = isofilters.join('');             return selector;         }          $( window ).on( 'hashchange', function() {             //var aniengine = hashchanged ?

my problem in area:

if ( !isoptionlinkclicked ) {                 // iterate on options                 var hrefobj, hrefvalue, $selectedlink;                 ( var key in options ) {                     hrefobj = {};                     hrefobj[ key ] = options[ key ];                     // convert object parameter string                     // i.e. { filter: '.inner-transition' } -> 'filter=.inner-transition'                     hrefvalue = $.param( hrefobj );                     alert(hrefvalue);                     // matching link                     $selectedlink = $optionsets.find('a[href="#' + hrefvalue + '"]');                     selectlink( $selectedlink );                 }             }

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.
