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 ...
Applications of mesh adaptation techniques could be found in the numerical solution of PDE's or in the optimal triangulation of surfaces for shape representation or graphic display. The scope of this work is to verify through numerical experiments the effe ...
Coadsorption of CO and butane on a Pt(533) surface leads to a dynamical system in which both molecules influence the adsorption behavior of each other. Adsorbing butane on a Pt(533) surface with CO on atop step sites leads to tilting of CO molecules of at ...
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. ...
This paper proposes an efficient method to estimate the distance between discrete 3D surfaces represented by triangular 3D meshes. The metric used is based on an approximation of the Hausdorff distance, which has been appropriately implemented in order to ...
A method to obtain quantitative information about the chemical composition spatial distribution on rough (Ra between half a micrometer and tens of micrometers) surfaces is developed by using a Raman microscopy technique. It is tested on a wrinkled polyeste ...
Monolayers of gramicidin A, pure and in mixts. with dimyristoylphosphatidylcholine (DMPC), were studied in situ at the air/H2O and air/D2O interfaces by polarization-modulated IR reflection absorption spectroscopy (PM-IRRAS). Simulations of the entire set ...
This article addresses visualization of deformation or shape differences between bones while conventional visualization techniques are often about a single bone such as its 3D reconstruction. Given a pair of bones with a set of corresponding anatomical lan ...

The extraction of planar sections from volume images is the most commonly used technique for inspecting and visualizing anatomic structures. We propose to generalize the concept of planar section to the extraction of curved cross-sections (free form surfac ...
