Estimates the signal width of data input, using definition: rho = cumtrapz(t,x.^2)/trapz(t,x.^2)The integration limits go from mean(t)-w/2 and mean(t)+w/2; w is defined as the signal width, and gives the time at which rho % of the signal iscaptured. It is an informal measure of the localization... Platforms: Matlab

This include a MEX-DLL file which is an implementation of R L Siddon's refined method by Jacob for the calculation of ray path integral in PET/CT system image reconstruction. This is based on Line Intersection Length model to calculate probability matrix elements. Inputs are the LOR number and a... Platforms: Matlab

In this demo, we show how you can create the 3D visualization of a wind farm consisting of identical wind turbines in the ocean. Using the extrusion node in VRML, we model the complex 3D geometry of a blade. We use a NACA 0015 Thickness Form as the wing section of the blade, vary its size and... Platforms: Matlab

This program calculates view factors and radiative heat transfers between two or many surfaces. Surfaces must be polygons or circles. For each surface, you must enter the parameters relative to their geometry, the emissivity, either the temperature or the radiative balance. For each surface, the... Platforms: Matlab

We calculate the number of photon with two methods. We dertermine the differnce of luminance for two (or many ) wavelength.We can find the error with the temperature and the wavelength for different acquisition time and many geometry. Platforms: Matlab

The Noon Shadow model shows the geometry of the shadow cast by a gnomon at noon. Users can change the orientation of the gnomon as well as its latitude. The height of the gnomon and its shadow length are displayed in Earth radius units. It is a supplemental simulation for an article by Barbara... Platforms: Mac

meshconv converts to and from several popular 3D file formats. Currently only geometry conversion is supported. Platforms: Mac

JEDI Math is a free mathematical library developed under the MPL for Delphi, Kylix, FPC and Lazarus. The library provides routines for matrices/vectors, regression, geometry, physics, equation rendering and raytracing among others. Platforms: *nix

Geomview is an interactive 3D viewing program for Unix. Geomview lets you view and manipulate three-dimensional objects: you use the mouse to rotate, translate, zoom in and out, and so on. Geomview can be used as a standalone viewer for static objects or as a display engine for other programs... Platforms: *nix

This application is intended to be a tool for easy, almost automatic, creation and calculation of gear transmission finite element models. It consists of a geometry and mesh generator based on GMSH and a finite element model based on GETFEM++. Platforms: *nix

Navlib is a collection of algorithms created to solve the navigation problem for 2D non-holonomic vehicles. It includes code for computational geometry, system identification, path planning, and control. Written in C++ with python extensions. Platforms: *nix

Spinsim GSL is a software that calculates magnetization of multi-layer nanostructures with different applied current and external field. It takes a variety of parameters specifying its physical properties and geometry. Platforms: *nix

JSXGraph is a cross-browser library for interactive geometry, charting, function plotting and data visualization in a web browser. It is implemented completely in javascript, does not rely on any other library, and uses SVG and VML. JSXGraph is easy to embed and has a small footprint: less than... Platforms: *nix

This tool provides an OpenStreetMap data parser to turn them into a nodes-edges adapted for routing applications. == INPUT FORMAT == The input is an OpenStreetMap XML file. The file can be read: * from a plain .osm file * from a bzip2 file * from a gzip file == OUTPUT FORMAT == The output can... Platforms: *nix

The Xchar module offers a set of programs for keyboard (mouseless) management (raising, focussing, moving, resizing) of X windows. It includes a taskbar. It is useful if you use so many windows that they can't all be seen at once. Xchar is not a 'window manager' like fvwm or metacity. In fact it... Platforms: *nix
