The Wagner hierarchy is known so far to be the most refined topological classification of $\omega$-rational languages. Also, the algebraic study of formal languages shows that these $\omega$-rational sets correspond precisely to the languages recognizable by finite pointed $\omega$-semigroups. Within this framework, we provide a construction of the algebraic counterpart of the Wagner hierarchy....

Notre modèle prédit que les dynamiques positionnelles, relatives aux opinions exprimées, et les dynamiques relationnelles, relatives aux relations affectives et à l’organisation du groupe, sont constamment en interaction et...

The solvability of the problem of fair exchange in a synchronous system subject to Byzantine failures is investigated in this work. The fair exchange problem arises when a group of processes are required to exchange digital items in a fair manner, which means that either each process obtains the item it was expecting or no process obtains any information on the inputs of others. After introducing...

Self-categorization theory is a social psychology theory dealing with the relation between the individual and the group. It explains groupe behaviour through self- and other's conception as members of social categories, and through the attribution of the prototypical categories' characteristics to the individuals. Hence, it is a theory of the individual that intends to explain collective...

This Ph.D. thesis was carried out in parallel to an European project funded by the fourth framework programme of the European Commission (DG XII, Standards, Measurement and Testing). This project, named SMT-CT98-2277 was funded, for the Swiss part, by the Federal Office of Education and Science (OFES, Bern, Switzerland). The aim of the project was to develop a harmonised, collaboratively tested...

The use by police services and inquiring agencies of forensic data in an intelligence perspective is still fragmentary and to some extent ignored. In order to increase the efficiency of criminal investigation to target illegal drug trafficking organisations and to provide valuable information about their methods, it is necessary to include and interpret objective drug analysis results already...
