Abstract

This paper introduces J-SIM, a package that enables arbitrary numbers of geographically dispersed users to actively share, control and collaborate on designs and simulations of dynamic systems through internet connections. J-SIM resembles Simulink and is compatible with MATLAB, which it uses as its mathematical engine. J-SIM was developed for distance learning and collaboration and it can be shared in real-time over internet connections through browsers. It is totally platform and browser independent and allows several sharing modes to accommodate typical situations encountered in collaborative design and educational domains. Users can alternate control of J-SIM on-the-fly without loss of data. J-SIM conserves bandwidth by using client-plotting facilities by using a specially developed graphics system (the WebEng GL Plotter or WGLP). This paper gives an overview of J-SIM, the reasons for its development, the modes of operation and some insight gained from limited trials of the software.
