Vogel Method

This is a small project aiming to prove a theory that grids can be solved using only the "possible value" method, whereby the numbers are filled in according the condition that that position has only one possible value, in filling this in, possible values matching this number on the same x and y...

The method connects to SMTP servers and retrieves email account information.Email address syntax checking does not conform to RFC2822, however, it will work fine on normal email address' format.

This is a simple method for silence removal and segmentation of audio streams that contain speech. The method is based in two simple audio features (signal energy and spectral centroid). As long as the feature sequences are extracted, as thresholding approach is applied on those sequence, in...

Let us assume the signal model:Y(k)=HX(k)+B(k)This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources. See reference [CHE91] Chen....

This is an implementation of Ephraim's MMSE log-STSA method 1985. The decision-directed method is used for tracking of a priori SNR tracking.


Platforms: Matlab

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...

This solver computes the internal loads on each member of two dimensional isostatic truss structures by using the method of joints.Since the Theory of Deformations is not considered in this program, displacements of the structures are not computed. All assumptions of Rational Mechanics are made...

This include a MEX-DLL file which is an implementation of R L Siddon's refined method by Jacob for the calculation of ray path integral in PET/CT system image reconstruction. This is based on Line Intersection Length model to calculate probability matrix elements. Inputs are the LOR number and a...

The script quasi_newton_dfp.m optimizes a general multi variable real valued function using DFP quasi Newton method. During the iterations if optimum step length is not possible then it takes a fixed step length as 1. For the theory any good book on optimization techniques can be consulted. This...
