Robots Collision Avoidance Using Learning through Imitation

Aurel Fratu, Jean-Paul Becar

This paper deals with the collision avoidance of the cooperative robots using the learning through imitation. Each physical robot acts fully independently, communicating with corresponding virtual prototype and imitating her behavior. Each physical robot reproduces the motion of her virtual…

A Resonant-Superlinear Elliptic Problem Revisited

Mabel Cuesta, Colette De Coster

We consider the resonant-superlinear elliptic problem−∆u=λ1u+(u+)q+f(x), withDirichlet boundary conditions on a bounded regular domain ofRN. We assume that 1<q<N+1N−1,f∈Ls(Ω) withs>Nsatisfies∫Ωfφ1<0 and (λ1,φ1) is the first eigenpair of−∆onH10(Ω). We apply a non-well ordered lower and…

Numerical approximation for options pricing of a stochastic volatility jump-diffusion model

Rajae Aboulaich, Fouzia Baghery, Abdelilah Jraifi

In this paper, we are interested in pricing options (European and Quanto) by a Model in which the asset prices follow a jump-diffusion model with a stochastic volatility in n dimensions. The stochastic volatility also follows the jump-diffusion in d dimensions. We've already stated the…

Calcite as a bone substitute. Comparison with hydroxyapatite and tricalcium phosphate with regard to the osteoblastic activity

Francine Monchau, Philippe Hivart, Benoit Genestie, Feng Chai, Michel Descamps, Hartmut Frederic Hildebrand

Close to the bone mineral phase, the calcic bioceramics, such as hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP), are commonly used as substitutes or filling materials in bone surgery. Besides, calcium carbonate (CaCO3) is also used for their excellent biocompatibility and bioactivity.…

Convergence order of a numerical scheme for sweeping process

Frederic Bernicot, Juliette Venel

In a previous paper, an implementable algorithm was introduced to compute discrete solutions of sweeping processes (i.e. specific first order differential inclusions). The convergence of this numerical scheme was proved thanks to compactness arguments. Here we establish that this algorithm is of…

Animation réaliste d’une caméra pour la stop motion : de la modélisation à la prise de vue

Laura Saini, Gudrun Albrecht, Nicolas Lissarrague, Lucia Romani

L’article présente un nouveau système permettant de produire des mouvements de caméra réalistes pour l’animation stop motion. Le système permettra d’enrichir les logiciels d’animation 3D classiques (comme par exemple Maya et 3D Studio Max) afin de leur faire contrôler des mouvements de caméra pour…, The article presents a new system that allows to create realistic camera movements for a stop motion animation. The system improves traditional 3D software animation programs (for example Maya and 3D Studio Max) for creating stop motion camera movements by using a haptic interface. After describing…

Lower and upper solutions for the heat equation on a polygonal domain of R2

Colette De Coster, Serge Nicaise

We consider the nonlinear periodic-Dirichlet heat equation on a polygonal domain of the plane in weighted Lp-Sobolev spaces equation presented Here f is Lp(0; T;Lpμ(Ω)-Caratheodory, where L pμ(Ω) = {v ε Lploc(Ω) : rμv ε Lp(Ω)}, with a real parameter μ and r(x) the distance from x to the set of…

Spectral analysis and exponential or polynomial stability of some indefinite sign damped problems

F. Abdallah, D. Mercier, Serge Nicaise

In this paper, we consider two damped wave problems for which the damping terms are allowed to change their sign. Using a careful spectral analysis, we find critical values of the damping coefficients for which the problem becomes exponentially or polynomially stable up to these critical values.

Photocatalytic solution discoloration and self-cleaning by polyester fabric functionalized with ZnO nanorods

Munir Ashraf, Philippe Champagne, Anne Perwuelz, Campagne Christine, Anne Leriche

Polyester fabric was functionalized with ZnO nanorods grown by hydrothermal method. The ZnO seeds were deposited on fabric which provided the sites for growth of nanorods. The functionalized fabric showed self-cleaning by degrading color stains and solution discoloration under the effect of…
