The design of highly complex particle detectors used in High Energy Physics involves both CAD systems and physics simulation packages like GEANT4. GEANT4 is able to exchange detector geometries with CAD systems, conforming to the Standard for the Exchange ...
This paper starts by presenting several examples of original flexible bearings and flexible articulated structures having 1 to 6 degrees of freedom to illustrate how flexures can soundly be used in high precision robotics. Then, the influence of the electr ...
We describe a general method for the quantitative determination of the interlayer mass transport in epitaxial growth. Through measurement of the nucleation rate on top of islands as a function of island size and temperature, the additional barrier for an a ...
There is a large body of research on motion control of legs in human models. However, they require specification of global paths in which to move. A method for automatically computing a global motion path for a human in a 3D environment of obstacles is pre ...
Availability of Visible Human Dataset (VHD) has provided numerous possibilities for its exploitation in both medical applications and 3D animation. We present our interactive tools which enable extraction of surfaces for different organs, including bones, ...
The recent development of temperature controlled scanning tunneling microscopy opened the door to a fascinating new world on the nanometer scale. The atomic scale information obtained provides unprecedented insight into the kinetics of surface phenomena su ...
A simple method has been developed for the prodn. of Au surfaces which are uniformly flat over large areas. Si wafers serve as substrates for the evapn. of thin Au layers. A glass slide glued onto the Au film allows successful sepn. of the Au layer from th ...
Novel lactide-based poly(ethylene glycol) (PEG) polymer networks (GL9-PEGs) were prepared by UV copolymerization of a glycerol-lactide triacrylate (GL9-Ac) with PEG monoacrylate (PEG-Ac) to use as scaffolds in tissue engineering, and the surface properties ...
Using a first-principles approach, we study Si 2p core-level shifts at water and hydrogen covered Si(001)2 x 1 surfaces. After allowing for full relaxation of the surface structures, core-level shifts are calculated including core-hole relaxation effects. ...
Modern transmission electron microscopes offer imaging capabilities down to the atomic lattice resolution, as well as crystallographic and chemical microanalysis with 2-nanometer diameter probes in thin foils. These analytical microscopes are powerful tool ...
