c# - How to organise namespaces within an assembly to reflect design -

-

i organise assembly code write reflects intended design. received understand namespaces principal way organise types achieve this.

the issue have assembly, assembly, say, uses layer of implementation classes. of classes in layer1 part of implementation of layer1 , i'd reflect in way structure code. first thought try make classes in layer1 private, can see this not possible.

logically, layer1 exposing classes a1, b1, c1 etc. , uses classes a2, b2, c2 etc.

namespace assembly.layer1 {     // "interface layer1"     class a1 // ...     class b1 // ...     class c1 // ...     // "implementation of layer1"     class a2 // ...     class b2 // ...     class c2 // ... } // (one file per class)

it seems 1 way address put a2, b2, c2 etc new namespace, assembly.layer1.layer2. then, when i'm writing code in top-level namespace , using assembly.layer1, intellisense shows me classes assembly.layer1 exposes. also, by convention, should refer 1 layer down in namespace hierarchy @ time. right approach?

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

Image
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.
