How to delete superclass entity whose subclass entity has been removed in Hibernate? -

-

there 2 entity classes , b, , instances a, b (a , b have same id). b subclass of ( b extends a). removed entity "b" database. then, saw "a" has not been deleted. s want. @ point of code, want remove "a" too. when entitymanager.remove(a) throws exception saying, detached entity can t removed. seems removing subclass entity makes superclass entity detached although superclass entity remains in database. can me remove instance a.

note: , b have same ids because when create b, automatically created same id ( rule of inheritance).

you should use session.delete(b). deletes both records database.

after having deleted b record native sql delete statement, have delete record accordingly native delete statement.

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
