Contraction
This is an extension of my single rotor analysis code.The function is based on the mathematical treatment of rotating rotors in "Principles of Helicopter Aerodynamics" by Dr. J.Gordon Leishman The numerical method does this by using Blade Element Momentum Theory (BEMT) to calculate the inflow...

This modification of fminsearch solves an issue with this simplex implementation when the function to minimize is smooth at a high scale, but rough at a low scale, i.e. when plotted with the parameters axis being (?10,10), there is a clear global extremum, but when zoomed (-0.1,0.1), the function...

Run this program by calling ?contractometer.m?When a contraction starts, click the mouse on the upper left green 'Contraction Start' button. This will start the clock in the upper right, and a horizontal red line will rise over time indicating the duration of the current contraction on the left...

Based on simple contraction/expansion rules, accordingly to weights given in matrices, which in turn coordinate random generation process for the plotted coloured points on screen, a simple Sierpinsky Triangle generation algorithm has been extended, giving in the result new formulas. And these...

This function takes as input the raw EMG data of a single muscle contraction. Output is a 1x2 array, the first number is the EMG onset, the second number is the EMG "offset" index.There needs to be enough data before the "on" burst to establish an average resting EMG level.The resting levels...

Judy is a C library that provides a state-of-the-art core technology that implements a sparse dynamic array. Judy arrays are declared simply with a null pointer. A Judy array consumes memory only when it is populated, yet can grow to take advantage of all available memory if desired. Judys...

BoliMonitor is a program for keeping track of pregnancy contraction durations and intervals between them. Just press the button whenever a contraction starts or ends. It keeps track of the lengths of the last contraction/interval, the average of the last three, and the overall average.

This function localizes a single source from a frame of data received at the microphones. It uses the Steered Response Power with the PHAse Transform (SRP-PHAT) as the functional. The true source location will have the maximum SRP-PHAT value. Stochastic Region Contraction (SRC) is used as the...
