This release contains SoundSim's 2.5D Acoustic Simulation Core and two sample MATLAB scripts to simulate a 5MHz tone burst scattering from an air bubble and an oil droplet suspended in water. See the included PDF for more information about the example simulations.This is an early release of... Platforms: Matlab

These programs were developped to exploit luminance or BRDF data from the EZ-Contrast instrument developped by Eldim. They are applicable to any measurment done using a ccd sensor.The developped library includes:- maxima research- Polar zenithal plot of ccd sections- Polar azimutal plot of ccd... Platforms: Matlab

Stokesian Dynamics, a method developed by Brady and Bossis in the 80s, simulates the 3D motion of hydrodynamically interacting spheres at low Reynolds numbers. This program was originally written by Professor Ron Phillips during his PhD thesis at MIT in 1989. The code was adapted from Fortran 77... Platforms: Matlab

There are two components in this group.1. Hohmann Transfer Example: This simulation starts with a craft/satellite in low earth orbit. A Hohmann Transfer is initiated to a 'random' destination altitude. This includes the delta V to move to a higher orbit, and then circularize the orbit once the... Platforms: Matlab

This can be considered the triangular version of file exchange id 20888 which uses quad patches. Platforms: Matlab

The program is an ordinary m-filethe matrix g(*,*) can be used to punch in the metric values in terms of symbolic variables x1,x2,x3,x4(co-ordinate axes)The program first computes the Affine connection(Christoffel symbols) stored in Gamma matricesThese are then used to construct and solvegeodesic...

I was asking myself what would be happen to the parallel light beams after passing a spherical glass. Do they pass through one point, exactly? I was interested in observing the result mathematically but solving the equations was difficult and time consuming for me. But afterwards I found it easy... Platforms: Matlab

A demo of some features of the jzy3d 3d graphics package from http://www.jzy3d.org/This PDF describes code for displaying jzy3d OpenGL-based 3D graphics in MATLAB. Code to run these demos is available as a Java jar file athttp://sourceforge.net/projects/waterloo/files/jzy3d uses the JOGL Java... Platforms: Matlab

The Newton's Law of Cooling model computes the temperature of an object of mass M as it is heated by a flame and cooled by the surrounding medium. The model assumes that the temperature T within the object is uniform. This lumped system approximation is valid if the rate of thermal energy... Platforms: Mac

The EJS Equinox Precession model illustrates the Copernican theory of Earth's orbit around the sun. The top window shows a view from outside the celestial sphere. The simulation shows the moving Earth along with its axis or rotation and the line of sight from Earth, through Sun, to the Celestial... Platforms: Mac

HEALPix is an acronym for Hierarchical Equal Area isoLatitude Pixelization of a sphere. As suggested in the name, this pixelization produces a subdivision of a spherical surface in which each pixel covers the same surface area as every other pixel. The figure below shows the partitioning of a... Platforms: Mac

The EJS Earth Orbit model illustrates the Copernican theory of Earth's orbit around the sun. The top window shows a view from outside the celestial sphere. The simulation shows the moving Earth along with its axis or rotation and the line of sight from Earth, through Sun, to the Celestial Sphere.... Platforms: Mac

This Spheres of Eudoxus model simulates the system devised by the Ancient Greek astronomer Eudoxus to model the motion of the planets. The model consists of four nested concentric spheres. The axis of each sphere is attached to the surface of the next sphere out. The planet itself is located on... Platforms: Mac

The Stellar Aberration 3D Model illustrates the phenomenon known as the aberration of starlight, first reported by James Bradley in 1729. Aberration occurs because light has a finite speed, and thus light from a star takes a finite amount of time to travel through the tube of a telescope. During... Platforms: Mac

The EJS Parallactic Proper Motion Model illustrates the phenomenon known as parallactic proper motion. Proper motion refers to the progressive (non-oscillatory) apparent motion of a star relative to more distant background stars. If this apparent motion is due to actual motion of the star through...

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink. Platforms: Mac

Realtime Sunlight Wallpaper is a simple but useful application which can retrieve an image from the Internet and set it as a wallpaper every 30 minutes. Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and... Platforms: *nix

The Sphere Online Judge, better known by its acronym, SPOJ, is an online archive of programming problems complete with a judge program that receives and checks submissions. Common utilities requested by users of this site include a user head-to-head comparer, a programming language preference... Platforms: *nix

An excellent free game based on the good old arkanoid. Here arkanoid has gained new appearance - it is turned upside down and you re not the enemy but the victim. There are big brown spheres moving at the top of the board that drop smaller colorful balls at your spheres. To get rid of them just... Platforms: Windows

Arkanizer is a new free version of the good well-known arkanoid. New features make this game even more interesting than before. The old blocks have been changed for spheres. The simple rules of the old game remained unchanged. Shoot at the spheres and see ho they change their colors. If you shoot... Platforms: Windows
