java - Register more than one MBean of same MBean class -

-

i want register more 1 mbean of same class.

i have hello class implementing hellombean interface.

now in main have 2 object of hello class , want register them both

mbeanserver mbs = managementfactory.getplatformmbeanserver(); objectname name = new objectname("mbeans:type=hello");  hello h1 = new hello(); hello h2 = new hello();  mbs.registermbean(h1, name); mbs.registermbean(h2, name);

this throws instancealreadyexistsexception .

how can register both h1 , h2, , using jconsole view both of them?

reason of this,

i want change attribute value of both h1 , h2 object through mbean

you need register each mbean unique name. if no longer receive exception when registering second mbean. have manage each bean separately (i.e. attribute on each home object set through individual mbeans).

mbeanserver mbs = managementfactory.getplatformmbeanserver();  hello h1 = new hello(); hello h2 = new hello();  mbs.registermbean(h1, new objectname("mbeans:type=hello-1")); mbs.registermbean(h2, new objectname("mbeans:type=hello-2"));

if want manage 2 hello objects @ same time through 1 mbean, (i.e change attribute on 1 mbean results in change on both hello objects) try using composite hello object , expose mbean.

common interface:

interface ihello {     void setattribute(int value); }

single hello object:

class hello implements ihello {     int attribute;      void setattribute(int value) {         attribute = value;     } }

composite hello object:

class compositehello implements ihello {     ihello[] hellos;      compositehome(ihello...hellos) {         super();         this.hellos = hellos;     }      void setattribute(int value) {         (ihello hello : hello) {             home.setattribute(value);         }     } }

register composite mbean:

mbeanserver mbs = managementfactory.getplatformmbeanserver();  hello h1 = new hello(); hello h2 = new hello(); compositehello composite = new compositehello(h1, h2); mbs.registermbean(composite, new objectname("mbeans:type=hello"));

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

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
