Abstract:
Les Alpes et les Pyrénées sont des chaînes de montagnes en domaine que l’on peut quasiment qualifier d’intraplaque compte tenu des taux de déformation horizontaux si faibles qu’on ne peut actuellement pas les quantifier avec la géodésie. Pourtant, la déformation tectonique et la sismicité actuelles en Europe occidentale sont essentiellement concentrées dans ces chaînes de montagnes. Nocquet (2012) a montré que le taux de déformation à travers l'Europe occidentale est faible et reste en dessous des incertitudes sur les mesures. Le mouvement horizontal à travers les Pyrénées et les Alpes occiden

Abstract:
The parallel and distributed platforms of High Performance Computing available today have became more and more heterogeneous (CPUs, GPUs, FPGAs, etc). Graphics Processing Units (GPU) are specialized co-processor to accelerate and improve the performance of parallel vector operations. GPUs have a high degree of parallelism and can execute thousands or millions of threads concurrently and hide the latency of the scheduler. GPUs have a deep hierarchical memory of different types as well as different configurations of these memories. Performance prediction of applications executed on these dev

Detta arbete redogör för hur användning av den nya nationella höjdmodellen (NNH) ur/i Lantmäteriet databas kan användas i olika terräng och vilka förutsättningar det finns för identifiering av specifika landskapselement i denna, manuellt och visuellt. Sedan 2009 har Lantmäteriet laserskannat hela landet, både på land och över vatten. Uppdraget är slutfört 2015. Målet med laserskanning är att framställa en rikstäckande höjdmodell med ett medelfel som är bättre än 0.5 m. Idag är all NNH-data tillgänglig som LAS-filer på Lantmäteriets databas.

Abstract:
Un réseau ad hoc de véhicules ou VANET est constitué de véhicules capables de s'échanger des informations par voie radio dans le but d’améliorer la sécurité routière ou de permettre I'accès à Internet pour les passagers, que nous avons choisi comme scénario. Par rapport à un réseau ad hoc classique, le VANET se différencie par une forte mobilité des nœuds rendant la topologie du réseau fortement dynamique. Pour contrer cette difficulté, nous nous sommes donc intéressés à la dynamique du trafic routier et aux problèmes des communications sans fiI. Nos questions étaient les suivantes : 1) à quoi

Cette étude va se focaliser sur trois aspects. Dans un premier temps, un effort sera porté sur l'aspect "localisation précise" du véhicule en mouvement. Pour cela, il est nécessaire de se pencher sur l'intégration et le traitement de l'information issue de systèmes hétérogènes de navigation: GPS et centrale inertielle (INS) auxquels sera rajoutée ensuite l'odométrie. La raison de cette intégration est d'exploiter les avantages de chacun des systèmes utilisés.
