Java Service Wrapper on Raspberry PI -

-

i'm trying use tanuki java service wrapper. hardware i'm using raspberry pi raspbian wheezy distribution. (see http://www.raspberrypi.org/downloads)

i've tried wrapper 32-bit armel release, problems reading libwrapper.so.

info | jvm 1 | 2013/04/24 20:15:34 | wrappermanager: initializing...
info | jvm 1 | 2013/04/24 20:15:42 | wrappermanager debug: attempt load native library name: libwrapper.so result: /usr/ihome/lib/libwrapper.so: /usr/ihome/lib/libwrapper.so: cannot open shared object file: no such file or directory

i've tried armhf release, since seems "apt-get java-7-openjdk", installed jdk-armhf version, there did "segmentation fault" when starting wrapper.

some info:

thanks in advance,

this issue has been discussed on java service wrapper user mailing list in this thread, here summary of resolution.

the armhf version of wrapper being built on armv7 platform , apparently not compatible armv6 hard float architectures. when using armel version of wrapper armhf jvm loading native library fails due target mismatch.

the suggested solutions either use armel jvm armel version of wrapper (since armv6 boards should support both) or create armhf binary board himself. second suggestion, pre-release (from sourceforge project site of wrapper) package has downloaded, extracted , following shell script executed:

./build32.sh release

with created binary wrapper able launch successfully. (the build process requires jdk , apache-ant installed)

cheers,

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
