python - FeinCMS allow a contenttype only once per page object -

-

is there default action allow contenttype once per page, other overriding admin form? documentation unclear this

i don't think there's out-of-the-box implementation, suggested 1 @ github. since feincms content type abstract django model class use clean method, e.g.

class foocontent(models.model):     content = models.bar('...')      class meta:         abstract = true      def clean(self):         if self.parent.foocontent_set.count() >= 1:             raise validationerror('foocontent allowed once per page.')      def render(self, **kwargs):         return render_to_string('content/foo.html', {             'content': self.content         })

this raise non field error on admin form.

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
