Bio-inspired cellular machines
Information technology has only been around for about fifty years. Although the beginnings of automatic calculation date from as early as the 17th century (W. Schickard built the first mechanical calculator in 1623), it took the invention of the transistor ...
EPFL2007Boundedly generated groups with pseudocharacter(s)
A note presenting the first examples of groups that are boundedly generated, have property (T) and have a one-dimensional space of pseudocharacters. ...
2006Comparison of four procedures for the identification of hybrid systems
In this paper we compare four recently proposed procedures for the identification of PieceWise AutoRegressive eXogenous (PWARX) and switched ARX models. We consider the clustering-based procedure, the bounded-error procedure, and the Bayesian procedure whi ...
Springer-Verlag2005Rate-Distortion Optimized Tree-Structured Compression Algorithms for Piecewise Polynomial Images
Martin Vetterli, Pier Luigi Dragotti, Minh Do, Rahul Shukla
This paper presents novel coding algorithms based on tree-structured segmentation, which achieve the correct asymp- totic rate-distortion (R-D) behavior for a simple class of signals, known as piecewise polynomials, by using an R-D based prune and join sch ...
2005Mathematical analysis and numerical simulation of the motion of a glacier
A numerical method for the simulation of the motion of a glacier in two and three dimensions is presented. Glacier ice is treated as an incompressible viscous fluid. The model equations are based on mass, momentum, energy conservation and a specific rheolo ...
EPFL2005One dimensional and multiscale models for blood flow circulation
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 ...
EPFL2004Analysis of lumped parameter models for blood flow simulations and their relation with 1D models
This paper provides new results of consistence and convergence of the lumped parameters (ODE models) toward one-dimensional (hyperbolic or parabolic) models for blood flow. Indeed, lumped parameter models (exploiting the electric circuit analogy for the ci ...
2004Fast Parametric Elastic Image Registration
We present an algorithm for fast elastic multidimensional intensity-based image registration with a parametric model of the deformation. It is fully automatic in its default mode of operation. In the case of hard real-world problems, it is capable of accep ...
IEEE2003MODFLOW/MT3DMS-based reactive multi-component transport modeling
This paper presents a three-dimensional, MODFLOW/MT3DMS- based reactive multicomponent transport model for saturated porous media. Based on a split-operator technique, the model, referred to as PHT3D, couples the transport simulator MT3DMS and the geochemi ...
20033-D integrable optoelectronic devices for telecommunications ICs
Mihai Adrian Ionescu, Luc Thévenaz, Philippe Renaud, Michel Declercq, Philippe Robert, Cyrille Hibert, Philippe Flückiger, Georges-André Racine
The design, fabrication and characterization of CMOS-compatible optoelectronic devices is discussed. All devices are fabricated on silicon on insulator (SOI) substrates which makes them suitable for three-dimensional (3-D) telecommunication photonic integr ...
