Simulation of Single Crystal Growth: Heat and Mass Transfer

The heat transfer (conductive, convective, radiative) and the related problems (the unknown phase boundary fluid/crystal, the assessment of the quality of the grown crystals) encountered in the melt and vapour growth of single crystal as well as the corresponding macroscopic models are reviewed. The importance of the adequate description of the optical crystal properties (semitransparency, absorption, scattering, refraction, diffuse and specular reflecting surfaces) and their effect on the heat transfer is stressed. The problems of the code verification and validation are discussed; differences between the crystal growth simulation codes intended for the research and for the industrial applications are indicated.

Mathematics of Human Motion: from Animation towards Simulation (A View form the Outside)

Simulation of human motion is the subject of study in a number of disciplines: Biomechanics, Robotics, Computer Animation, Control Theory, Neurophysiology, Medicine, Ergonomics. Since the author has never visited any of these fields, this review is indeed a passer-by's impression. On the other hand, he happens to be a human (who occasionally is moving) and, as everybody else, rates himself an expert in Applied Common Sense. Thus the author hopes that this view from the {\em outside} will be of some interest not only for the strangers like himself, but for those who are {\em inside} as well. Two flaws of the text that follows are inevitable. First, some essential issues that are too familar to the specialists to discuss them may be missing. Second, the author probably failed to provide the uniform "level-of-detail" for this wide range of topics.

Industrial Strength Software in Computer Based Engineering Education (CBEE): a Case Study

Challenging problems of modern engineering education and a role of information technology are reviewed. An importance of simulation of real world physical problems in both graduate and lifelong/corporate education is discussed. It is proposed to integrate the hypermedia theory courseware with industrial strength simulation software. As a proof of the concept an educational environment "Heat and Mass Transfer in Advanced Semiconductor Technology" has been developed.
