  • A new technique based on mini-UAS for estimating water and bottom radiance contributions in optically shallow waters 

    Montes Hugo, J. M.; Barrado Muxí, Cristina; Pastor Llorens, Enric (International Society for Photogrammetry and Remote Sensing (ISPRS), 2015)
    Text en actes de congrés
    Accés obert
    The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived ...

    Recent developments in unmanned aerial systems (UAS) provide new opportunities in remote sensing application. In contrast to satellite and conventional (manned) aerial tasks, UAS flights can be operated in a very short ...
  • Architectural support for task dependence management with flexible software scheduling 

    Castillo, Emilio; Álvarez, Lluc; Moreto Planas, Miquel; Casas, Marc; Vallejo, Enrique; Bosque, Jose L.; Beivide Palacio, Ramon; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Text en actes de congrés
    Accés obert
    The growing complexity of multi-core architectures has motivated a wide range of software mechanisms to improve the orchestration of parallel executions. Task parallelism has become a very attractive approach thanks to its ...
  • Vector processing-aware advanced clock-gating techniques for low-power fused multiply-add 

    Ratkovic, Ivan; Palomar Pérez, Óscar; Stanic, Milan; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Valero Cortés, Mateo (2018-04-04)
    Article
    Accés obert
    The need for power efficiency is driving a rethink of design decisions in processor architectures. While vector processors succeeded in the high-performance market in the past, they need a retailoring for the mobile market ...
  • Improving OpenStack Swift interaction with the I/O stack to enable software defined storage 

    Nou, Ramon; Miranda, Alberto; Siquier, Marc; Cortés, Toni (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Text en actes de congrés
    Accés obert
    This paper analyses how OpenStack Swift, a distributed object storage service for a globally used middleware, interacts with the I/O subsystem through the Operating System. This interaction, which seems organised and clean ...
  • Building microclouds at the network edge with the Cloudy platform
