Toward a power system emulation using analog microelectronics solid state circuits

Maher Kayal, Laurent Fabre, Ira Nagel

An analog electronics emulation solution is investigated in order to assess the state of a power system facing dynamic phenomena such as the transient stability. Two approaches are studied: DC emulation and AC emulation. Both are intended to be integrated ...

Characterizing electron temperature gradient turbulence via numerical simulation

Numerical simulations of electron temperature gradient (ETG) turbulence are presented that characterize the ETG fluctuation spectrum, establish limits to the validity of the adiabatic ion model often employed in studying ETG turbulence, and support the ten ...

On the behavior of spherical and non-spherical grain assemblies, its modeling and numerical simulation

Lionel Pournin

This thesis deals with the numerical modeling and simulation of granular media with large populations of non-spherical particles. Granular media are highly pervasive in nature and play an important role in technology. They are present in fields as diverse ...

Multi-Scale Simulation For Microsurgery Trainer

Etienne Burdet, Fei Wang, Zheng Li

For use in a Virtual Reality based training system for surgical micromanipulation, we have developed a fast multi- scale FEM algorithm that concentrates detail where needed while still handling global deformations. The resulting 6- to 7-fold speed up is pr ...

A New tool for the simulation of dynamic behaviour of hydroelectric power plants

François Avellan, Jean-Jacques Simond, Alain Sapin

An analytical approach allowing modelling transient phenomena in pipes, valves, surge tank and Francis turbines based on impedance method is developed. These models are introduced in a software called “SIMSEN”, which simulates the behaviour of complex appl ...

How (Un)Fair are the ABR Binary Schemes, Actually?

Jean-Yves Le Boudec, Milan Vojnovic

It is well known that a simple binary feedback rate--based congestion avoidance scheme cannot ensure a fairness goal of the Available Bit Rate (ABR) service, namely, max--min fairness. In this paper we show how the rates are distributed for the network con ...

Time-resolved Rayleigh scattering of excitons: Evidence for level repulsion in a disordered system

Vincenzo Savona

The theory of resonant Rayleigh scattering of light by excitons in a disordered quantum structure is presented. Disorder is modeled by a random Gauss distributed potential with finite correlation length in space. The time dependent scattered si,anal under ...

QOBJ modeling - A new approach in discrete event simulation

This paper deals with a new discrete event simulation modeling concept, called qobj, which comes from two well-known paradigms: objects and queuing networks. The first provides important conceptual tools for model organization, while the second one allows ...

Alluvionnement des retenues par courants de turbidité

Giovanni De Cesare

Reservoir sedimentation by turbidity currents All lakes created on natural rivers are subjected to reservoir sedimentation. The construction of a dam significantly modifies the flow conditions of natural streams inside and downstream of an artificial lake. ...
