Learning an event sequence embedding for event-based deep stereo

François Fleuret, Stepan Tulyakov, Michael Hirsch

Today, a frame-based camera is the sensor of choice for machine vision applications. However, these cameras, originally developed for acquisition of static images rather than for sensing of dynamic uncontrolled visual environments, suffer from high power c ...

Theory of the Drift-Wave Instability at Arbitrary Collisionality

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

A numerically efficient framework that takes into account the effect of the Coulomb collision operator at arbitrary collisionalities is introduced. Such a model is based on the expansion of the distribution function on a Hermite-Laguerre polynomial basis t ...

Ergodic behaviour of "signed voter models"

Thomas Mountford, Grégory Maillard

We answer some questions raised by Gantert, Lowe and Steif (Ann. Inst. Henri Poincare Probab. Stat. 41 (2005) 767 780) concerning "signed" voter models on locally finite graphs. These are voter model like processes with the difference that the edges are co ...

Thin film bulk acoustic wave resonators tuning from first principles

Alexander Tagantsev, Alexander Kvasov

Being important for the antiresonance frequency tuning of tunable thin Film Bulk Acoustic wave Resonators (FBARs), the non-linear electrostrictive coefficient was for the first time calculated for BaTiO3 and SrTiO3 using ab initio methods. Further, taking ...

Numerical algorithm for feedback linearizable systems

Dominique Bonvin, Philippe Müllhaupt

A numerical algorithm that achieves asymptotic stability for feedback linearizable systems is presented. The nonlinear systems can be represented in various forms that include differential equations, simulated physical models or lookup tables. The proposed ...

The global version of the gyrokinetic turbulence code GENE

Stephan Brunner, Xavier Lapillonne

The understanding and prediction of transport due to plasma microturbulence is a key open problem in modern plasma physics, and a grand challenge for fusion energy research. Ab initio simulations of such small-scale, low-frequency turbulence are to be base ...

Local nonreflecting boundary condition for time-dependent multiple scattering

Imbo Sim

Starting from from a high-order local nonreflecting boundary condition (NBC) for single scattering [25], we derive a local NBC for time-dependent multiple scattering problems in three space dimensions, which is completely local both in space and time. To d ...

Observation of Bs0 -> Ds()+ Ds()- using e+e- collisions and a determination of the Bs-Bsbar width difference Delta Gamma_s

Olivier Schneider, Aurelio Bay, Remi Léandre Albert Louvot, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Jean Wicht, Ji Hyun Kim

We have made the first observation of B-s(0) -> D-s(()()+) D-s(()()-) decays using 23.6 fb(-1) of data recorded by the Belle experiment running on the Y(5S) resonance. The branching fractions are measured to be B(B-s(0) -> Ds+Ds-) = (1.03(-0.32-0.25)(+0. ...

Illuminant retrieval for fixed location cameras

Sabine Süsstrunk, Joanna Marguier

Fixed location cameras, such as panoramic cameras or surveillance cameras, are very common. In images taken with these cameras, there will be changes in lighting and dynamic image content, but there will also be constant objects in the background. We propo ...

Modal Response of Hydraulic Turbine Runners

François Avellan, Eduard Egusquiza

The mechanical design of hydraulic turbines is conditioned by the dynamic response of the runner that is usually estimated by a computational model. Nevertheless, the runner has complex boundary conditions that are difficult to include in the computational ...
