This work presents an approach to data-driven motion generation for humanoid robots, which is based on the observation and analysis of human whole-body motions. To this end, we investigate how captured human motions can ...
Parameter dependencies for reusable performance specifications of software components
(2008)
To avoid design-related performance problems, model-driven performance prediction methods analyse the response times, throughputs, and resource utilizations of software architectures before and during implementation. ...
Parameterisation of electromagnetic showers and search for large extra dimensions in pp collisions at s = 14 TeV
(2006)
The emission of dibenzofurans and dioxins from industrial processes is a major environmental concern. Focussing on dibenzofuran, this study tend to improve our understanding of the general oxidation chemistry and to provide ...
Parameteranalyse eines redundanten Roboters mit Pivotpunkt-Restriktion
(2017)
Nowadays robots are used not only in production lines, but also in the field of medicine. In this thesis an analysis was performed which relates to a serial, redundant robot and its parameters. The pivot point restriction ...
Path regularity for stochastic differential equations in Banach spaces
(2007)
In this work we analzyse the Stochastic Cauchy Problem driven by a cylindrical Wiener process. Given the existence of solutions we show regularity of the paths of the solution. In dependence on properties of the operators ...
A New Concept for Mobile Environmental Education
