The time-harmonic Maxwell equations with impedance boundary conditions in convex polyhedral domains

Serge Nicaise, Jérôme Tomezyk

In this paper, we first develop a variational formulation of the time-harmonic Maxwell equations with impedance boundary conditions in polyhedral domains similar to the one for domains with smooth boundary proposed in [12, §4.5.d]. It turns out that the variational space is embedded in H 1 as soon…

Crosslinking chemistry of poly(vinylmethyl-<i>co</i>-methyl)silazanes toward low-temperature formable preceramic polymers as precursors of functional aluminium-modified Si–C–N ceramics

Diane Fonblanc, David Lopez-Ferber, Mélanie Wynn, Abhijeet Lale, Anne Soleilhavoup, Anne Leriche, Yuji Iwamoto, Fabrice Rossignol, Christel Gervais, Samuel Bernard

Crosslinking chemistry of a liquid poly(vinylmethyl-co-methyl)silazane with an alane hydride-based complex according to Si : Al ratios varying from 5 to 2.5 has been investigated in detail through the characterization of the as-obtained polymers using solid-state NMR, FT-IR and elemental analyses.…

Distributed leader-follower consensus for a class of semilinear second order multi-agent systems using time scale theory

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

The problem of distributed leader‐follower consensus for second‐order linear multiagent systems with unknown nonlinear inherent dynamics is investigated in this paper. It is assumed that the dynamic of each agent is described by a semilinear second‐order dynamic equation on an arbitrary time scale…

On the consensus tracking investigation for multi-agent systems on time scale via matrix-valued Lyapunov functions

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

This paper is devoted to the leader–follower consensus problem for high-order multi-agent systems with inherent nonlinear dynamics evolving on an arbitrary time domain. This problem is investigated using the time scale theory. Based on this theory, some sufficient conditions are derived to…

Computer Vision viewing over Mathematics

Jean-Charles Canonne, Eric Cartignies, Jean-Paul Becar, Laurent Vermeiren, Abdelmalik Taleb-Ahmed, Yassin El Hillali

The difference between having images of something and having a knowledge of the same thing has been a subject of reflection for centuries, and some of the most important Greek tragedies focused on that point. A great part of infor-mation now consists of images: image has become the language of many…
