The nonlinearity behaviour of magnetorheological fluid (MRF) can be described using a number established models such as Bingham and Modified Bouc-Wen models. Since these require the identification model parameters, there is need to estimate parameters' value carefully. In this paper, an optimization algorithm, i.e., Particle Swarm Optimization (PSO) utilized identify models' parameters. PSO alg...

Empruntant ses mécanismes d’élaboration à la fiction, le motif du complot juif constitue chez Albert Cohen l’objet de multiples fictions. La première strate ce se situe dans un discours social fait rumeurs et préjugés. Le Juif y est érigé en bouc émissaire d’une société qui lui attribuant tous les méfaits monde moderne tente rendre l’univers sa lisibilité. Mais s’inscrit aussi imaginaire romane...

The coupling with external mechanical systems such as oscillating masses working tuned mass dampers, dynamic absorbers, elasto-plastic and rigid walls is an effective method to reduce the displacements drifts of structures under loads. An alternative provided by structure independent, auxiliary system. This paper investigates seismic behaviour a rigidly coupled yielding system harmonic ground e...
