jboss7.x - slf4j don't work in JBOSS when using openJpa module -

-

my ear application runs fine when don't use openjpa. once use open jpa "slf4j fail load class blaaa ". how configure openjpa module use sl4j provide pom.xml , avoid error?

i use jboss 7.1.1

pom.xml

<properties>      <slf4j.version>1.7.3</slf4j.version>     <logback.version>1.0.10</logback.version>        </properties>     <dependency>         <groupid>org.slf4j</groupid>         <artifactid>slf4j-api</artifactid>         <version>${slf4j.version}</version>     </dependency>     <dependency>         <groupid>ch.qos.logback</groupid>         <artifactid>logback-classic</artifactid>         <version>${logback.version}</version>     </dependency>     <dependency>         <groupid>ch.qos.logback</groupid>         <artifactid>logback-core</artifactid>         <version>${logback.version}</version>     </dependency>

it looks you're getting 2 different versions of sfl4j. add <scope>provided</scope> slf4j dependency. other option provide jboss-deployment-structure.xml exclude servers slf4j.

example jboss-deployment-structure.xml:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">     <deployment>         <exclusions>             <module name="org.slf4j" />         </exclusions>     </deployment> </jboss-deployment-structure>

also make sure don't have transitive slf4j dependencies, sfl4j-jdk14.jar.

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
