The advanced simulations carried out using numerical continuation showed that the satellite can exhibit a wide variety of nonlinear phenomena including jumps, rich frequency

As the forcing amplitude is increased beyond a certain threshold, the response amplitude of the directly excited mode (plant) remains constant, while the response amplitude of

L’inconvénient d’un tel faisceau est que d’une part l’obtention d’un faisceau laser aussi étroit demande un télescope émetteur très grand et chère et d’autre part

Secondly, we generalize those methods to study a many-node thermal model of a spacecraft: this model also has a stable steady state under constant heat inputs that becomes a limit

Indeed, due to the fact that technical materials present a random surface morphology, an electron impinging the sample with a macroscopic

L’image de l’arrière-plan de la scène (background) est une représentation quasi-parfaite de l’environnement dans lequel évoluent les objets, elle est utilisée comme image

A binary fragmentation kernel induces a specific class of integral type branching kernels and taking as base process the solution of the initial (SDEF), we construct a branching
