stability and performance are two main issues in motion of bipeds. to ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. however, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. step length and step perio...

Many institutional and private investors seek for a long run excess return relative to a reference strategy (e.g. money market, bond index, etc.) which they want to attain under a minimal shortfall probability. In this article it is shown that even in the long run in order to attain a substantial excess return a high shortfall probability has to be accepted. In the model the prices of the asset...

Digitization of human motion using skeleton representations offers exciting possibilities for a large number applications but, at the same time, requires innovative techniques their effective and efficient processing. Content-based processing data has developed rapidly in recent years, focusing mainly on specialized prototypes with limited consideration generic management possibilities. In this...
