Solving large sparse linear systems is at the heart of many application problems arising from scientific and engineering problems. These systems are often solved by direct factorization solvers, especially when the system needs to be solved for multiple right-hand sides or when a high numerical precision is required. Direct solvers are based on matrix factorization, which is then followed by...

Services rely on replication mechanisms to be available at all time. The service demanding high availability is replicated on a set of machines called replicas. To maintain the consistency of replicas, a consensus protocol such as Paxos or Raft is used to synchronize the replicas' state. As a result, failures of a minority of replicas will not affect the service as other non-faulty replicas...

Task granularity, i.e., the amount of work performed by parallel tasks, is a key performance attribute of parallel applications. On the one hand, fine-grained tasks (i.e., small tasks carrying out few computations) may introduce considerable parallelization overheads. On the other hand, coarse-grained tasks (i.e., large tasks performing substantial computations) may not fully utilize the...

Mémoire de bachelor : Haute Ecole de Travail Social, 2013.
Ce Travail de Bachelor tente de répondre au mieux à cette question : Quelles caractéristiques et quel accompagnement éducatif pour les jeunes mettant en échec la prise en charge habituelle de l’institution ? L’objectif de la recherche vise à amener une réflexion et des pistes d’intervention au sujet des adolescents difficiles pour lesquels le fonctionnement éducatif institutionnel...
