MCX is a GPU-accelerated, general-purpose, physically-accurate and feature-rich 3-D light transport simulator. It is one of the fastest simulators because it can use tens of thousands of GPU threads to simulate photons in parallel.

...It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. The latest version is v3.3.1 (IDL & Matlab) and v3.3.4 (Python). ...

FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

A package for transient and steady state simulation of organic solar cells.

With Virtual Reflectometer (VR), you can simulate the basic alignment scans of a basic X ray reflectometer (diffractometer) with a Goebel mirror using ray tracing. With this program, you can characterize reflectometers and get a reflectometer-dependent overillumination correction for X Ray Reflectivity (XRR) scans. The pogram serves as an educational tool for explaining alignment and for a proper overillumination correction of XRR data. !!

OS X FOSS portable applications are packaged so you can carry around on any portable device, USB thumb drive, iPod, portable hard drive, memory card, other portable device (or also on your internal hard disk), taking your preferences with you.

...Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs

This package includes a collection of MATLAB files which are designed to: 1. Given a calibration scan of the image of a point emitter with an engineered point spread function (PSF), 2. Perform a phase retrieval algorithm based on maximum likelihood estimation (MLE) of a phase aberration term which is added to the theoretical pupil function of the imaging system. 3. Use the phase-retrieved pupil function to perform single-emitter localization.

A handle graphics package for Octave, the Free alternative to matlab. OctPlot provides quality postscript(TM) and screen graphics.

Cell Motility Analysis Package analyzes timelapse sequences of moving cells. Various quantitites characterizing motility are calculated, including normal velocity of the membrane, cell contact area, and spatio-temporal auto-correlation functions.

Magnetostatic finite differences simulation tool based on GNU Octave and a Perl/Tk user interface.

Compton simulate the interactions betwen a laser beam and an electron beam to create high energy photons (X-rays).
