Pisces Characteristics

This function is able to detect almost all types of properties/characteristics present in an LPP such as unbounded solution, alternate optima, degenaracy/cycling and infeasibilty. It only fails to work when there are redundant constraints present in the problem. However, it is rare and can be...

The 3 phase induction motor is modeled to accept the No-Load & Blocked rotor test results for determining the equivalent circuit parameters. The model is used to simulate various performance characteristics. these characteristics can be viewed using a scope.

Both functions caculate the Lomb normalized periodogram (aka Lomb-Scargle, Gauss-Vanicek or Least-Squares spectrum) of a vector x with coordinates in t, which is essentially a generalization of the DFT for unevenly sampled data.The codes are transcriptions from Fortran of the subroutines found in...

This small contribution is useful in cases where you search for the position of a peak within an intensity matrix (correlation or energy fields) of low resolution. Since this is only a 2nd-order-fit the sub-sample accuracy will only be acceptable as long as the peak area is 'smooth' around the...
