From time immemorial, the security realm and personal identification task had shown progress by employing technological means like secret knowledge as passwords and Personal Identification Numbers, and by using personal possessions as identity cards and Radio Frequency Identification chips. As opposed to these means which are...

Developing, testing and operating complex machinery and repairing it under time pressure if it breaks down are some of the new skills, professionals in many occupations have to learn as quickly as possible. Actions on machinery and plants are trained in individual lessons on an immersive virtual model. This paper introduces the...

As far as I know, the systematic study on chalcogenide glasses as semiconductors was initiated around the 1950s by a research group headed by B.T. Kolomiets of the Ioffe Physico-Technical Institute. During the half-century that followed, amorphous semiconductors have acquired their own citizenship as an unchallenged, independent area of...

Computers play an increasingly important role in our society. A breakdown of all computer systems would cause a breakdown of almost all activities of daily life. Furthermore, personal computers are available in almost every home in the industrialized world. But there is one sector where computers have a more strategic role, and that...
