Existence and Uniqueness Theorems in Two-Dimensional Nematodynamics. Finite Speed of Propagation

The paper is devoted to the two-dimensional Ericksen-Leslie system describing the nematodinamics of liquid crystals. The moment of inertia of molecules is supposed to be strictly positive. The existence of the solution was proved in the case of periodic do ...

Approaching on-line estimation of swimming instantaneous velocity using a wearable IMU

Kamiar Aminian, Grégoire Millet, Farzin Dadashi

The goal of this study is to assess the possibility of accurate on-line instantaneous velocity estimation in swimming. Having an on-line tool, coaches could provide immediate feedback about performance to trainees. More importantly, by on-line monitoring o ...

Hopping process of bound excitons under an energy gradient

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Mehran Shahmohammadi

We report on the mechanism of hopping for bound excitons under an energy gradient. By means of a Monte-Carlo simulation, we show that this mechanism explains the movement of bound excitons observed experimentally. We show that the speed of the excitons dec ...

Design of a Wearable Perturbator for Human Knee Impedance Estimation during Gait

Roger Gassert, Olivier Lambercy

Mechanical impedance modulation is the key to natural, stable and efficient human locomotion. An improved understanding of this mechanism is necessary for the development of the next generation of intelligent prosthetic and orthotic devices. This paper doc ...

Empirical and analytical analyses of laboratory granular flows to investigate rock avalanche propagation

Vincent Labiouse, Irene Manzella

Laboratory experiments which consist of releasing dry rigid non-cohesive grains or small bricks on an unconfined chute have been designed to investigate rock avalanche propagation mechanisms and to identify parameters influencing their deposit characterist ...

Effective information flow over mobile adaptive networks

Ali H. Sayed

Collective motion is a remarkable phenomenon in biological systems. There have been several models in the literature to regenerate this type of motion, such as averaging consensus strategies where nodes continuously average the velocity vectors of their ne ...

Triangular formation control using range measurements: an application to marine robotic vehicles

Jorge Miguel Dias Almeida Rodrigues Soares, António Pedro Rodrigues de Aguiar

This paper addresses the problem of maintaining an autonomous robotic vehicle in a moving triangular formation by regulating its position with respect to two leader vehicles. The robotic vehicle has no a priori knowledge of the path described by the leader ...

Heel and Toe Clearance Estimation for Gait Analysis Using Wireless Inertial Sensors

Kamiar Aminian, Benoît Mariani

Tripping is considered a major cause of fall in older people. Therefore, foot clearance (i.e., height of the foot above ground during swing phase) could be a key factor to better understand the complex relationship between gait and falls. This paper presen ...

Motion of Spin Polariton Bullets in Semiconductor Microcavities

Timothy Chi Hin Liew

The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...
