Ballistic Coefficient

Used on cellular phones to filter outbackground noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop).Includes a tutorial on how to use statistics (correlation coefficient) to calculate the signal...

Method 1 . Using Step Response and Delay Time and Time Constant Parameters.Method 2 . Using proportional controller action only. you should find critical gain and corresponding critical period.all results come in 2 different output shape.1- Controller with (Kp - Ti - Td)2- Controller with (Kp -...

It calculates the Spearman rank correlation coefficient from 2 or more data sets, and the associated t-test and p-values. The code is adapted with major changes from the Numerical Recipes book (http://www.nr.com/)Example:>> x = [1 2 3 3 3]';>> y = [1 2 2 4 3; rand(1,5)]';>> [r,t,p] = spear(x,y)>>...

In many cases, simulating a dynamical system is best achieved by defining several modes in which it can exist and modeling each mode independently. This approach is known as "hybrid modeling". There is significant academic literature on the subject, but at its most basic level, a hybrid model...

Cohen's kappa coefficient is a statistical measure of inter-rater reliability. It is generally thought to be a more robust measure than simple percent agreement calculation since Kappa takes into account the agreement occurring by chance.Kappa provides a measure of the degree to which two judges,...
