-

this jar in not loading in tomcat 7 environment locally. worked fine yesterday when shut down day. nothing has changed, when start morning presented with. nothing has changed - really. opened eclipse start working , testing web app - cannot found , returns 404.

what cause jar not load? have no errors in project , have cleaned it.

the offending jar located:

the console output after cleaning:

edit

what trying start web app, cannot found because jar not loading. it's physically should - again worked yesterday , of morning not.

servlet-api.jar loaded tomcat_home/lib directory. can suggest clean tomcat server , restart it. clean tomcat need "window -> show view -> other -> servers" , you'll able see tomcat server. right click , hit "clean...". hope should resolve problem working fine yesterday , not working today without change.

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
