This model simulates three phase inverter. Sawtooth waveform has been used as the carrier. Triplen of level 1/6 of reference were injected in the reference to utilize the maximum DC link voltage. The output voltage range increases by injecting the triplen harmonics in the reference provided that... Platforms: Matlab

The Hardy Weinberg equilibrium is a fundamental law in genetic.This function was deeply rewrited.If a locus is biallelic the function use the exact Hardy Weinberg test (similar to Fisher exact test) analyzing all possible tables. If you download TERNPLOT functions (ID:2299) the function plots a... Platforms: Matlab

groups_euclid calls gp_euc and euclid to separate a set of harmonics into families or groups of related harmonics, each with its own fundamental tone. The euclid() function accepts two real numbers with uncertainty intervals, and returns their greatest common divisor (gcd), also a real number.... Platforms: Matlab

One of the fundamental motivations for feature selection is to overcome the curse of dimensionality problem. This code presents a novel feature selection method utilizing a combination of differential evolution (DE) optimization method and a proposed repair mechanism based on feature distribution...

Digital Karma is designed to model & analyze interaction at a fundamental level. It allows researchers to quantify the interactions of any phenomenon, and study the underlying processes graphically. We simulate the evolutionary processes at work behind any system by modeling the interactions... Platforms: Matlab

Goertzel algorithm generalized to non-integral multiples of fundamental frequency.The conventional Goertzel Algorithm can be used to compute individual DFT coefficients. In case we need to compute some values of DTFT (that means, non-integer multiples of the fundamental frequency), slight... Platforms: Matlab

The program can get the 2-D impulse response of a 2-D recursive discrete system in 2-D digital domain. For a 2-D recursive discrete system, the inverse 2-D z transform can be implemented by a 2-D IIR filter [1-3].Copyright (C) Yang XIAO, Beijing Jiaotong University, Aug.1, 2007, E-Mail:...

Combining hum removal, buzz removal, brickwall filtering, and spectrum analysis into one easy to use plug-in, MR Hum is the perfect tool to clean up recordings with any sort of hum or nasty buzz. The hum removal section works by applying a set of notch filters spaced at multiples of the... Platforms: Mac

The list of noise sources is long, but since the soccer world cup has begun it is clearly dominated by the Vuvuzelas. Their deafening noise even renders a TV broadcast an acoustic challenge. An algorithm which has been developed at the institute is now able to reliably suppress the disturbing... Platforms: Mac

The most fundamental question in audio production, how loud is it? Simple and yet elusive, with loudness inconsistency and incompatibilities present every day in broadcasts across the world. With detailed, objective loudness measurement, history and logging facilities, VisLM provides a simple,... Platforms: Mac

JOhm is a blazingly fast Object-Hash Mapping library for Java inspired by the awesome Ohm. The JOhm OHM is a modern-day avatar of the old ORM's like Hibernate with the difference being that we are not dealing with an RDBMS here but with a NoSQL rockstar. JOhm is a library for storing objects in... Platforms: Mac
