datasw
datasw, a tool for rapid processing of HPLC-SAXS data.
Small-angle X-ray scattering (SAXS) in solution is a common low-resolution method which can efficiently complement high-resolution information obtained by crystallography or NMR. Sample monodispersity is key to reliable SAXS data interpretation and model building. Beamline setups with inline high-performance liquid chromatography (HPLC) are particularly useful for accurate profiling of heterogeneous samples. The program DATASW performs averaging of individual data frames from HPLC-SAXS... -

MSU's Sparse Fourier Repository
The Home of DMSFT, AAFFT, GFFT, and MSFFT.
A collection of sparse Fourier transform codes developed by faculty at MSU. Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.) AAFFT, implemented by Mark Iwen in 2008. This code is easy to use, and documented well, but not implemented very... -

disp2sif
Stress intensity factor (SIF) calculation from crack tip displacements
The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle. -

PALMA-leafmov
Command-line leaf movement analysis tool for Arabidopsis thaliana
PALMA is a simple, command-line tool to determine rhythmic leaf movement behavior from time-lapse photography pictures of Arabidopsis thaliana. PALMA consists of two components: PALMA1 extracts leaf and cotyledon tip positions from time-lapse photography studies and parses them into .csv-files which are read by PALMA2. PALMA2 performs Fast-Fourier transformation and non-linear least squares fitting to determine the periods, amplitudes and phases of rhythmic leaf movements. -

Brainwave Analyzer
Discrete Fourier Transform of Brainwaves
The Brainwave Analyzer is NOT a finished program. So far it does do Discrete Fourier Transform of brainwaves (very slow), but does not yet do Fast Fourier Transform of brainwaves, nor does it yet calculate frequency. (Later more complete versions should be coming over the next few months.) Written in C# 2010 Access file and csv sample files included. Program assumes that access file is at: C:\Openvibe\OpenVibe.accdb The Brainwave Analyzer is a free open source program written by ??? Based... -

A More Accurate Fourier Transform
Computes Accurate Fourier Transform via Explicit Integration not FFT
Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented... -

FFTL
Templated Fast Fourier Transform in C++
Now moved to GitHub: https://github.com/CoreyShay/FFTL Provides some relatively easier to use than normal templated FFT classes written in C++. This is currently still a work in progress, but the FFT portion (complex and real) both output the correct results, and the code executes very quickly, around only 30% or so slower than the much more difficult to compile FFTW on SSE enabled platforms. Though optimized code only runs on SSE (x86) based platforms, it's a very simple matter to port the... -

High Speed Image Analysis for MATLAB
An integrated toolbox for MATLAB analysis of high-speed video
High-speed imaging is a powerful tool for capturing fast events, but converting qualitative video observations to quantitative analysis is challenging. This toolbox is being developed to support analysis of high-speed video in Hall thrusters and other plasma devices. In particular, it enables visualization and Fourier analysis of rotating spoke instabilities in the annular Hall thruster discharge channel. We currently have two developers but are always open to more. Feedback is also...
