In the recent past a number of concepts have achieved prominence in the quest for basic principles of informatics with long-term validity. Particularly at schools providing an all-round education, it makes sense – and is necessary – to concentrate on basic concepts. The fact is that strictly product-related knowledge is inadequate, and in some cases already(More)
Die Entwicklung moderner Osteosyntheseverfahren ermöglicht sowohl bei sagittaler Spaltung im Unterkiefer wie bei derLe-Fort-Osteotomie im Oberkiefer, die Segmente in einer gewünschten Position einzustellen. Eine Langzeitimmobilisation entfällt. Ein besonderes Verfahren zur Repositionierung der Kondylen wurde bereits vorgestellt. In Erweiterung dieses(More)
The discussion in literature about chondrosarcoma of the hand arising from solitary preexistent enchondroma is very controversial. Well-documented, proved cases are rare. Treatment of choice a 77-year-old woman with chondrosarcoma (Grade 2) of proximal phalanx of the right index finger was ray resection. The 43-year-old X-ray film showed typical enchondroma(More)
This paper describes work in progress on automatic generation of "impact sounds" based on physical modelling. These sounds can be used as non-speech audio presentation of objects and as interaction-mechanisms to non visual interfaces. In this paper especially we present the complete physical model for impact sounds "spherical objects hitting flat plates or(More)
This paper presents work in progress on automatic generation of "environmental sounds" based on physical modelling. The increase in complexity of the Graphical User Interfaces , the expansion of Virtual Reality and multimedia applications has led to the necessity of using sound to ease the human computer interaction. This category of sounds can be used as(More)

These sounds can be used as non-speech audio presentation of objects and as interaction mechanisms to non visual interfaces. Different approaches for synthesizing impact sounds, the process of recording impact(More)
Knowledge Engineering In order to define relevant parameters and possibilities for describing environmental sounds, we were concentrating on the following knowledge engineering techniques: interviewing experts accompanying sound designers during their work analysing sounds in film documents In terv i ewing Exper t s In the last years many automobile and(More)
