Amb l'increment del número de constel·lacions de satèl·lits, cada cop es necessiten més Ground Stations per tal de controlar-les. Això dificulta més i més la seva gestió i operació, implicant també un augment en la càrrega ...

New challenges to file systems’ metadata performance are imposed by the continuously growing average number of files existing in file systems. The traditional component based lookup approach can become a performance ...

This paper reports on a multi-fold approach for the building of user models based on the identification of navigation patterns in a virtual campus, allowing for adapting the campus’ usability to the actual learners’ needs, ...

The evolution of High-Performance Computing (HPC) platforms enables the design and execution of progressively larger and more complex workflow applications in these systems. The complexity comes not only from the number ...

Estudi i desenvolupament d'una plataforma orientada a sistemes distribuïts per a l'avaluació del rendiment d'aplicacions que s'executen en aquests entorns de grans requeriments de transferència d'informació, com és el cas ...

Data collection is a key scenario for the Internet of Things because it enables gathering sensor data from distributed nodes that use low-power and long-range wireless technologies to communicate in a single-hop approach. ...

English: Cloud computing is a new computing paradigm that aims to transform computing into a utility, just as electricity is. With cloud computing, users will contract for on-demand and scalable resources rather than having ...

A lease is a token which grants its owner exclusive access to a resource for a defined span of time. In order to be able to tolerate failures, leases need to be coordinated by distributed processes. We present FaTLease, ...

The Grid is an heterogeneous and dynamic environment which enables distributed computation. This makes it a technology prone to failures. Some related work uses replication to overcome failures in a set of independent ...
