sql - Optimize MySQL query because it gets time out -

-

can me optimizing query. can not execute because phpmyadmin connection gets timed out , have no access change time out parameter.

here query:

insert `goods` (`goods_id`, `price`, `name`) select `sales_goods`.`goods_id`, `sales_goods`.`price`, `sales_goods`.`goods_id` `sales_goods` `sales_goods`.`sales_goods_id` in (     select max(`sales_goods`.`sales_goods_id`)     `sales_goods`     `sales_goods`.`sales_goods_id`     in (         select `sales_goods`.`sales_goods_id` `sales_goods`          `sales_goods`.`goods_id` not in (select `goods`.`goods_id` `goods`)     )     group `sales_goods`.`goods_id` )

aside ensuring tables propery indexed can replace in subqueries inner join, , not in subqueries left join/is null, should improve performance:

insert `goods` (`goods_id`, `price`, `name`) select  `sales_goods`.`goods_id`,          `sales_goods`.`price`,          `sales_goods`.`goods_id`    `sales_goods`         inner join         (   select  max(`sales_goods`.`sales_goods_id`)                `sales_goods`                     left join `goods`                         on `goods`.`goods_id` = `sales_goods`.`goods_id`               `goods`.`goods_id` null             group `sales_goods`.`goods_id`         ) maxsalesgoods             on maxsalesgoods.sales_goods_id = `sales_goods`.`sales_goods_id`

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
