web services - Entity fetched from a webservice: how to integrate in DDD model? -

-

i have "process" application complex model (simplified here). application has webservice such:

webservice             | application behind webservice ------------------------------------------------------ processdto             | process     .getlabel()        |     .getlabel()                        |     .getsubcomponents()                        |     .execute(input) // calls processcomponent.execute                        | processcomponent                        |     .execute(input) processservice         | processrepository     .findprocess(id)   |     .findprocess(id)     .executeprocess(..)|

the problem is: how integrate process entities inside application using webservice?

i thinking of creating process entity instead of directly using dto entity.

for example, in application, have module has process.

i can hook in orm "association" part not problem. problem how module executes process?

  • by calling processservice: that's ugly because i'll end anemic process entity doesn't offer domain logic. furthermore, make module entity use service, not right?

  • by adding execute() method in process? entity method calls service not good

in ddd, external web services should encapsulated anti-corruption layer (acl). in acl, dto contracts of web service should mapped locally defined value objects.

as far calling external service, should done application service hosting corresponding use case, not entities observed.

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.
