Nowadays, the anticipation of parking-space demand is an instrumental service in order to reduce traffic congestion levels urban spaces. The purpose our work study, design and develop a parking-availability predictor that extracts knowledge from human mobility data, based on anonymized displacements area, also weather conditions. Most existing solutions for this prediction take as contextual da...

Data availability is crucial to overall application availability. This paper describes data failures and classifies them as either physical or logical. Physical data failures such as data loss and corruptions are introduced in the I/O layers; logical data failures are introduced in the application layer. Current data protection techniques are geared towards physical data failures. This paper re...

Low carbon footprint energy sources such as solar and wind power typically suffer from unpredictable or limited availability. By globally distributing a number of these renewable sources, these effects can largely be compensated for. We look at the feasibility of this approach for powering already distributed data centers in order to operate at a reduced total carbon footprint. From our study w...
