The dilation matrix associated with the three-dimensional (3-D) face-centered cubic (FCC) sublattice is often considered to be the natural 3-D extension of the two-dimensional (2-D) quincunx dilation matrix. However, we demonstrate that both dilation matri ...
Two of the most basic problems encountered in numerical optimization are least-squares problems and systems of nonlinear equations. The use of more and more complex simulation tools on high performance computers requires solving problems involving an incre ...
The aim of this work is to provide mathematically sound and computationally effective tools for the numerical simulation of the interaction between fluid and structures as occurring, for instance, in the simulation of the human cardiovascular system. This ...
We discuss the basic elements of the discontinuous Galerkin methods for the time-domain Maxwell's equations. A one-dimensional example is developed in detail from which the extension to two- and three-dimensional algorithms are minimal. A few examples are ...
We show that it is possible to increase the performance of the coupled-dipole approximation (CDA) for scattering by using concepts from the sampling theory. In standard CDA, the source in each discretized cell is represented by a point dipole and the corre ...

A three-dimensional generalization of a Potts pseudo-atomic model based on a stochastic process has been implemented on a CRAY-2 computer to study large networks during long simulations. The three-dimensional network was then sampled with two-dimensional c ...
The present work is part of a general research program conducted by the Machine-Tools and Automata Laboratory of the Federal Institute of Technology in Lausanne on "Synthetic Intelligence". The final goal is to automatize design using computers in mechanic ...
The design of a radiation driven capsule suitable for use in a heavy ion beam driven inertial confinement fusion reactor system is discussed. Numerical simulations of compression, ignition and burn of the capsule are presented. These simulations have been ...
An in-situ, mid-IR sensor was used to monitor the major analyte concns. involved in the cultivation of Gluconacetobacter xylinus and the prodn. of gluconacetan, a food-grade exopolysaccharide. To predict the analyte concns., three different sets of std. sp ...
A monocrystalline silicon lever with an integrated silicon tip for a force/friction microscope was realized. Theoretical studies have been carried out to find the shape and dimensioning according to the mechanical system requirements. Moreover, sharp tips ...
