Signal Modelling using piecewise linear chaotic generators

In this paper the modeling of a signal by a chaotic generator with respect to a specified signal statistic will be considered. To accomplish that, the considered class of n-dimensional piecewise linear Markov generators will first be analyzed analytically, ...

Extended states in one-dimensional random potential

We report the first experimental evidence of the existence of extended states in one-dimensional random potentials. Our results are obtained by investigating photoconductivity and optical absorption of GaAs/(AlGa)As disordered superlattices. The experiment ...

Time-dependent damage evolution and failure in materials .2. Simulations

William Curtin

A two-dimensional triangular spring network model is used to investigate the time-dependent damage evolution and failure of model materials in which the damage formation is a nucleated event. The probability of damage formation r(i)(t) at site i at time t ...

Ozone LIDAR as an analytical tool in effective air pollution management. The Geneva 96 campaign

Hubert van den Bergh, Bertrand Calpini, Valentin Simeonov

The LIDAR principle for air quality and meteorol. measurements is presented, followed by different examples of vertical O3 profiles and time series obtained with a new optical layout of the EPFL-LPAS DIAL system using dual telescope detection. These data w ...

Modeling and simulation of electromechanical transducers in microsystems using an analog hardware description language.

Philippe Renaud, Alexis Boegli

The analytical modeling and simulation of conservative electrostatic, electromagnetic and electrodynamic transducers found in microsystems using a non-linear lumped-parameter approach is presented in this paper. A comparison is made between this approach a ...

Determinants of stroke volume and systolic and diastolic aortic pressure

Nikolaos Stergiopoulos, Jean-Jacques Meister, Nico Westerhof

We investigated how parameters describing the heart and the arterial system contribute to the systolic and diastolic pressures (Ps and Pd, respectively) and stroke volume (SV). We have described the heart by the varying-elastance model with six parameters ...

Analysis of the vertical displacement of energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria, Aurélien Vadrot

Over the last fifty years, the interaction factor method has been widely used to address the vertical displacement and the increased deformation of conventional pile groups subjected to mechanical loads when group effects and interactions occur among the p ...
