  • In the quest for knowledge, it is not uncommon for researchers to push the limits of simulation techniques to the point where they have to be adapted or totally new techniques or approaches become necessary. True multiscale modeling techniques are becoming increasingly necessary given the growing interest in materials and processes on which large-scale properties are dependent or that can be tuned by their low-scale properties. An example would be nanocomposites, where embedded nanostructures completely change the matrix properties due to effects occurring at the atomic level.

  • Computer simulation is used to reduce the risk associated with creating new systems or with making changes to existing ones. More than ever, modern organizations want assurance that investments will produce the expected results. For instance, an assembly line may be required to produce a particular number of autos during an eight hour shift. Complex, interacting factors influence operation and so powerful tools are needed to develop an accurate analysis.

  • Wow. Silverlight has really come a long way since I started using it. It’s kind of interesting to look back a mere two years (roughly) and think about how the workflow has changed. Of even more interest is the staggering speed at which new features are being added. In the time I’ve been using Silverlight, it has grown from a somewhat limited toolset to an ever-more-impressive technology that has really started to come into its own. Silverlight has started to change the way people think about producing rich applications for the Web....

  • When motion capture is used on line, it is possible to create applications based on a full 3-D interaction metaphor in which the specifications of deformations or motion are given in real-time. This new concept drastically changes the way of designing animation sequences. Thalmann [1993] calls all techniques based on this new way of specifying animation VR-based animation techniques. He also calls VR devices all interactive devices allowing to communicate with virtual worlds.
