Facilities to present simulation results as animations on the Internet have been developed. They can take simulation results from the modeling and simulation environment Dymola and convert them to a Virtual Reality Model Language (VRML) representation, which is the new Internet protocol for displaying three dimensional graphical worlds with sound effects. Mathematical models for sound have been de
The possibility of supervising controllers in buildings with the help of Internet and Java is investigated. The task is to develop a computer system with necessary software that enables connection over Internet from a client computer to a server computer that contains information about the controllers in a data base. It should be possible to study values and attributes of the controllers. Java and
This report investigates time optimization of a process where brazed heat exchangers are soldered in a vacuum furnace. This process consists of three phases, heating soldering and cooling. Physical models have been obtained by using stationary conditions. These are not sufficient to describe the actual very complex behavior. Instead, nonphysical models have been identified. Simulations of the heat
