Tabu search is an established heuristic optimisation technique for problems where exact algorithms are not available. It belongs to the same family as simulated annealing or genetic algorithms. It extends the basic iterative improvement scheme by adding control learning. A technique of this kind, intensification, captures experience established on a frequency-based analysis of past search. Expe...

From a field-theoretical approach, it has been possible to develop a physically valid theory of partial discharge transients. Thetheoryis baseduponthe concept of the charge induced upon the detecting electrode by the partial discharge. This induced charge is shown tobe composedo f a componentassociated withtheactual spacecharge inthevoid, and one related to changes in the bulk po la r i za t io...

Comment le massacre est-il traité par la philosophie ? Un petit parcours de Platon à Giorgio Agamben, en passant Polybe, Cicéron, Montaigne et Grotius qui s’adonnent citation des Anciens, montre que philosophique est réticent aborder violence extrême masse. Plusieurs hypothèses sont envisagées : groupe constitution, comme lors d’un imprévu, n’est pas pensé antique ; rapproché stasis fait l’obje...
