BlueSim is a JSR-82 simulator built using Java. BlueSim JSR-82 Simulator allows you to test your JSR-82 applications without any need of actual bluetooth device or a real bluetooth stack. BlueSim is a 100% JSR-82 compliant, implementing the complete JSR-82 specification. This means you can compile and test your JSR-82 application over BlueSim, and if it runs over BlueSim, it should run over any standard JSR-82 stack. BlueSim is developed completely using Java, and includes the GCF. This means BlueSim JSR-82 Simulator can be run on any platform. BlueSim runs fine over J2SE and J2ME. Multiple instances of BlueSim JSR-82 Simulator can be run on different machines in the local intranet. BlueSim will automatically detect each other instances. This allows you to simulate the Bluetooth environment completely, and test the server and client applications simultaneously. Configuring BlueSim is very easy. Just edit the configuration file, and specify the device name and device address. That's all!. No need of any heavy configurations, no J2ME projects needed, No phone selections. It cant get any simpler that this.

SNMP Agent Simulator







Educational orbit and gravitation simulator for high school, college and beginning university physics and astronomy. Input mass, radius, coordinates and velocity components of 2 to 10 bodies manually or by dragging and dropping predefined bodies. Then watch how the orbits evolve under the mutual gravitaional attractions. Save and print the simulation. Great for 'lab exercises' in gravitational physics or for verifying numerical answers to textbook problems. Includes 30 introductory to advanced premade simulations with activities page in html-format. Simulations include elliptical satellite orbits, Kepler's laws, double star, geocentric and heliocentric world view, Lagrange points, gravity assist, Hohmann orbit, extrasolar planet, inner solar system. Uses actual pictures of planets. Plot orbits in a plane or in 3D. View time, distances, speeds, accelerations, energies and acceleration vectors as they change. Adjust the simulation speed to fit your computer. Zoom and change parameters during the simulation. Run up to four simultaneous simulations. Tutorial and context-sensitive help included.
