android - ongoing notification opening existing Activity -

-

i want show notification while timer running , when user clicks notifiaction opens timer activity.

        mnotificationmanager = (notificationmanager) getsystemservice(context.notification_service);          intent intent = new intent(this, activity.class).addflags(intent.flag_activity_reorder_to_front);          pendingintent pendingintent = pendingintent.getactivity(this, 0, intent, pendingintent.flag_update_current);

the problem right when start timer , press home , click notification opens activity running timer.

but when start timer, open activity (via actionbar.navigation_mode_list), press home , click notification opens new activity (empty).

i thought addflags(intent.flag_activity_reorder_to_front); (thats used navigate between activities)

im using android:launchmode="singletop" , android:configchanges="orientation|screensize"

for every activity.

i wouldn't rely on activity persisting , unnecessary

store timer start time sharedpreferences , load start time when activity recreated.

if meant happen after time, countdown time, you'll need set alarm , handle way.

remember activities ui. don't trust activity doing when user isn't looking @ it.

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...
