Adjusted complex position of extra sources in the image sources method

Thomas Guignard, Vincent Martin

Using a series development of the integral solution, a formal backing of the presence of image sources in geometrical acoustics methods has been shown. Furthermore, the existence of "invisible" sources is suggested, especially in the vicinity of obtuse ang ...

Microscopic aspects of the region-by-region polarization reversal kinetics of polycrystalline ferroelectric Pb(Zr,Ti)O-3 films

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Enrico Colla, Lisa Malin

The region-by-region polarization switching in ferroelectric Pb(Zr,Ti)O-3 thin films sandwiched between Pt electrodes has been directly observed using piezoelectric scanning probe microscopy. A resolution improved by one order-of-magnitude compared to the ...

Softening and hardening transitions in ferroelectric Pb(Zr,Ti)O3 ceramics

Hysteretic and nonlinear dielectric behaviour in ferroelectric ceramics has been of interest since 1950s, when these materials found application in various electronic devices. Presently, these phenomena concern with important areas of science, technology a ...

Immersive vehicle simulators for prototyping, training and ergonomics

Daniel Thalmann

In most vehicle simulators, complete physical mockups equipped with steering wheel, gearshift and pedals are required. These devices are essential in trying to simulate real conditions, but as a drawback the system becomes expensive, huge (non mobile), and ...

Méthode d'analyse des écoulements 3D à surface libre

Sonia Kvicinsky

Free surface flows are extremely complex and appear in various cases such as chemistry, oceanography, thermodynamics and turbomachinery. Their complexity is due to the fact that they are composed of two distinct phases which are only separated by a thin in ...

On the Accuracy of MANET Simulators

André Schiper, David Cavin, Yoav Sasson

The deployment of wireless applications or protocols in the context of Mobile Ad-hoc NETwork (MANET), often requires to step through a simulation phase. For the results of the simulation to be meaningful, it is important that the model on which is based th ...

Facile: A Language and Compiler for High-performance Processor Simulators

James Richard Larus

Architectural simulators are essential tools for computer architecture and systems research and development. Simulators, however, are becoming frustratingly slow, because they must now model increasingly complex micro-architectures running realistic worklo ...

Modeling and simulation methods to assess EM terrorism effects

Michel Ianoz

High power microwave (HPM) and ultra wide band (UWB) sources can represent a threat for the sensitive equipment of various military and civil targets. The paper focuses on effects on aircraft and discusses the modeling possibilities available today to esti ...

Fast Out-of-order Processor Simulation Using Memoization

James Richard Larus

Our new out-of-order processor simulatol; FastSim, uses two innovations to speed up simulation 8--15 times (vs. Wisconsin SimpleScalar) with no loss in simulation accuracy. First, FastSim uses speculative direct-execution to accelerate the functional emula ...
