Magnitude Normalization

DBSchema::Normalizer is a database normalization. It can convert a table from 1st to 2nd normal form. SYNOPSIS # the easy way is to give all parameters to the constructor # and then call do() # use DBSchema::Normalizer; my $norm = DBSchema::Normalizer->new ( { DSN => $DSN, username =>...

Web100 project was created to produce a complete host-software environment that will run common TCP applications at 100% of the available bandwidth, regardless of the magnitude of a networks capability. While the national high-performance network infrastructure has grown tremendously both in... Platforms: *nix

EigenMS is a stand-alone (or Matlab) bottom-up proteomics data normalization algorithms. EigenMS utilized SVD to detect significant trends in the data and eliminates those attributable to bias. EigenMS eliminates effects from known and unknown factors. Platforms: Windows, Mac, Linux

FPlus is an application that implements several database theory algorithms such as Fmin, tableaux, normalization, attribute closure, key calculation, efficiency, etc.Test the applet at:http://fplus.sourceforge.net Platforms: Windows, Mac, Linux

The function calculates the averaged power spectrum with proper normalization, and even if the signal is given in volts, the value is the power value. Requirements: - MATLAB 7.7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

It will take a vector as input, with a lower and upper limit used for normalization.The script normalizes each feature value and calculates its complement. To run the script, unzip the archived files, open Matlab and type "compgui" in the Matlab prompt. Requirements: - MATLAB 7.4 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

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... Platforms: Matlab

Simple implementation of [1] with small modification. Hopefully this is going to help beginners in speech/audio signal processing.[1] X. Zhu, G. T. Beauregard and L. L. Wyse, "Real-Time Signal Estimation From Modified Short-Time Fourier Transform Magnitude Spectra", IEEE Trans. on Audio, Speech,... Platforms: Matlab

This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if... Platforms: Matlab

A Simulink model that generates and displays a simple cosine wave. The model computes the cosine function using the continuous phase method, which is based on Euler's formula for the complex exponential. The cosine generator is provided as a subsystem, which the user can copy-and-paste into other... Platforms: Matlab
