ember.js - Re-compute an Ember object's property every interval -

-

currently have simple ember object, has 2 properties: startedat , endedat.

based on these properties, have computed property islive. time comparison current time.

when rendering handlebar template highlight items adding class highlight.

<li {{ bindattr class="event.islive:highlight" }}>...</li>

i'd update template every 5 seconds or so, know islive needs re-calculated. how need go that?

app.event = ember.object.extend({   endedat: null,   startedat: null,    islive: function() {     if (!this.get('startedat') || !this.get('endedat')) {       return false;     }      var = moment();      return (now.diff(moment(this.get('startedat'))) >= 0 &&             now.diff(moment(this.get('endedat'))) < 0);   }.property('startedat', 'endedat')  });

i have done similar regular ember view {{view app.timerview}}.

app.timerview = ember.view.extend({   tagname: 'time',   template: ember.handlebars.compile('{{ view.now }}'),    init: function() {     this._super();     this.set('now', moment().format('hh:mm:ss'));   },    now: null,    willinsertelement: function(evt) {     var self = this;      var intervalid = setinterval(       function() {         self.set('now', moment().format('hh:mm:ss'));       }, 1000);      this.set('interval', intervalid);   },    willdestroyelement: function(evt) {     clearinterval(this.get('interval'));   }  });

but can't seem apply same logic regular object. point me in right direction please.

i believe i'd need in controller according these guides.

i've used solution presented here: http://livsey.org/blog/2013/02/20/tick-tock/

to continuously check on passage of time vs timestamp.

you create clock object , initializer described in post, , create islive property:

.property("startedat", "endedat", "clock.minute") });

using clock.minute fire update every minute. use clock.second if time sensitive (or speed development.

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
