Using a table of initial positions and velocities derived from JPL's "Horisons" System (http://ssd.jpl.nasa.gov/?horizonshttp://ssd.jpl.nasa.gov/?horizons) , it is possible to predict the motion of all of the elements in the table.
The default table (supplied) contains 25 bodies - the planets of the Solar System (including the moons of Earth, Jupiter and Saturn), Voyager 1 and 2 as well as Halley's Comet....
Simulates the motion of a single planet in a binary star solar system. Uses Simulink to solve the equation of motion for the planet. The stars are assumed to be stationary. Have fun changing the system parameters to generate strange orbits!
This is a solution for the keplar problem for orbit insertion. Given a burn out velocity and a flight path angle, what is the apogee of the orbit, and the circular orbit that can be achived with one burn at apogee? The delta-velocity for...
There are 400 balls in 2d that has finite size and can pass trough each other with friction. At distances more than size they have gravitation forces. Initially system rotated slightly as global. Code well...

You can add effects or links from your flash program. Separate background layer, you can change to your own colour or delete to make transparent.
100% vector animation drag to any size without loss of graphic quality.
NBODYVECT - Fully vectorized n-body equation
nbodyVect(x0,dx0,mus,t) integrates the n-body equations of motion using either a symplectic second order integrator, or any of the standard built-in or user supplied first order integrators.
vec2orbElem(rs,vs,mus) converts positions (rs) and velocities (vs)
of bodies with gravitational parameters (mus) to Keplerian orbital elements.

This programs explains the formulation of Ybus by singular transformation method of an IEEE 14 bus system
Sample showing how to modify the system menu of Form (change, delete, add new items in menu). + Example of showing the ShellAbout dialogue (as in standard Windows programs).Exe-demo available from Homepage
The programs compute the enthalpy versus composition diagram for ethanol-water binary system at 760mmHg and 76 mmHg. We also draw the tie lines and the conjugate line.
A Rubyesque binding to the XOSD (X On-Screen Display) library, which allows programs to display text, progress bars, and sliders onto an X Window System screen with arbitrary position and style.
Sample showing how to modify the system menu in forms (change, delete, add new items in menu) and example of showing the ShellAbout dialogue (as in standard Windows programs).
This programs uses a for loops only to calculate the state space parameters and then finds the covariance matrix bu using a for loops then check for the stability of this system by cheking the diagonal of the K matrix by <<1>> if itis...
Several programs exist for measuring solar cell data, mainly written in labview. Since data analysis is more native to me in matlab, and I needed some custom instrumentation, I wrote my own in MATLAB. Some other industrial programs exist on the...

WESP is a collection of subtle scripts and programs written in several languages (C, /bin/sh, (g)awk, ruby, icon) that breaths a new life into the WEB system for literate programming by Donald Knuth (and CWEB by Knuth/Sylvio Levy).
SVSS is a web subversion system, it use a graphic interface to manage versions of programs on a hosted server pr your own server, is totally builded on PHP with a mysql database, you just need php and mysql installed on your server.
Startup Manager is search your system for programs that run automatically on Windows startup, after every system reboot. Startup Manager will found the startup programs (even if they are hidden in the system registry) and shows them in three...
