We present an extension of Freund and Schapire's AdaBoost algorithm that allows an input-dependent combination of the base hypotheses. A separate weak learner is used for determining the input-dependent weights of each hypothesis. The error function minimi ...
We present a comprehensive first-principles study of the ballistic transport properties of low-dimensional nanostructures such as linear chains of atoms (Al, C) and carbon nanotubes in the presence of defects. An approach is introduced where quantum conduc ...
Three-dimensional numerical simulations are performed to investigate the dynamic tensile properties of ceramics, using explicit dynamic FEM and cohesive element techniques. A micro-cracking model considering the stochastic distribution of internal defects ...
This thesis aims at improving the perceptional side of interaction to enable the handling of more complex situations. For the Swiss National Exposition Expo.02 the robot RoboX and an event-driven interaction system have been designed by members of our lab. ...
Current web infrastructure is oriented on human-machine interactions. Developments for next generation large-scale information systems (such as Web Services and ebXML) however aim to allow for automated interactions between arbitrary systems / services. Th ...
After a quarter century of mobile robot research, applications of this fascinating technology appear in real-world settings. Some require operation in environments that are densely cluttered with moving obstacles. Public mass exhibitions or conventions are ...
We present an atomic force microscope study of nanoscopic sliding friction on diamond, diamond-like carbon, and on three CrN thin films with varying hardness obtained by different growth temperatures. For the CrN films, we show that the changes in the fric ...
Geomorphologic dispersion relates to the fraction of the variance of residence time distributions that can be directly linked to the heterogeneity of the paths available to hydrologic runoff of a river basin in response to suitable rainfall pulses. It thus ...
The original TCV control system was designed in the late 1980s to be inherently network based in that all control operations were performed from X-windows terminals and the control computers were networked. Using VMS-VAX technology, the acquisition system ...
In a growing number of applications, different complementary views of real-world objects are needed. This is particularly true in spatial modelling - where the designer can propose different geometries for a given spatial object - or, in temporal modelling ...
