  • Implementando acceso directo y secuencial a colecciones de datos mediante aspectos 

    Marco Gómez, Jordi; Franch Gutiérrez, Javier; Álvarez Canal, Jordi (2005-03)
    Artículo
    Acceso abierto
    Las bibliotecas de colecciones de datos juegan un papel importante en el desarrollo de software basado en componentes. Las colecciones contenidas en las bibliotecas de este tipo (JCF, STL, LEDA, etc.) implementan un modelo ...

  • Exact and heuristic allocation of multi-kernel applications to multi-FPGA platforms 

    Shan, Junnan; Casu, Mario R.; Cortadella, Jordi; Lavagno, Luciano; Lazarescu, Mihai T.
    Texto en actas de congreso

    FPGA-based accelerators demonstrated high energy efficiency compared to GPUs and CPUs. However, single FPGA designs may not achieve sufficient task parallelism. In this work, we optimize the mapping of high-performance ...

  • Semantic integration on spatial databases: SIT-SD prototype 

    Morocho, Villie; Pérez Vidal, Lluís; Saltor Soler, Félix Enrique (2003)
    Texto en actas de congreso
    Acceso abierto
    Progress on data integration has come to the point that we must deal with the need of semantic integration. ln this work we present a prototype of an integration tool of information sources (Semantic lntegration Tool for ...

  • Dynamic pipelining of multidimensional range queries 

    Duch Brown, Amalia; Lugosi, Daniel; Pasarella Sánchez, Ana Edelmira; Zoltan Torres, Ana Cristina (2019-06-07)
    Artículo

  • Hybrid evolutionary data analysis technique for environmental modeling 

    Acosta, Jesus; Nebot Castells, M. Àngela; Fuertes Armengol, José Mª (International Centre for Numerical Methods in Engineering (CIMNE), 2006)
    Texto en actas de congreso
    Acceso abierto
    In this work an evolutionary fuzzy system (EFS) is presented and applied to an environmental problem, i.e. modeling ozone concentrations. The hybrid system is composed by a FIR methodology and a genetic algorithm (GA) that ...

  • Defining inheritance in i* at the level of SR intentional elements 

    López Cuesta, Lidia; Franch Gutiérrez, Javier; Marco Gómez, Jordi (CEUR-WS.org, 2008)
    Comunicación de congreso
    Acceso abierto
    The is-a relationship among actors has been introduced since the very beginning in the i* framework. However, the effect of this construct at the level of intentional elements and dependencies is not always completely ...

  • Visual analysis of research paper collections using normalized relative compression 

    Vázquez Alcocer, Pere Pau (Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-21)
    Artículo
    Acceso abierto
    The analysis of research paper collections is an interesting topic that can give insights on whether a research area is stalled in the same problems, or there is a great amount of novelty every year. Previous research has ...

  • Sesquickselect: One and a half pivots for cache-efficient selection 

    Martínez Parra, Conrado; Nebel, Markus; Wild, Sebastian (Curran, 2019)
    Texto en actas de congreso
    Acceso abierto
    Because of unmatched improvements in CPU performance, memory transfers have become a bottleneck of program execution. As discovered in recent years, this also affects sorting in internal memory. Since partitioning around ...

  • Deep learning is blowing in the wind. Deep models applied to wind prediction at turbine level 

    Manero Font, Jaume; Béjar Alonso, Javier; Cortés García, Claudio Ulises (Institute of Physics (IOP), 2019)
    Texto en actas de congreso
    Acceso abierto
    Wind Energy generation depends on the existence of wind, a meteorological phenomena intermittent by nature, with the consequence of generating uncertainty on the availability of wind energy in the future. The grid stability ...

  • Polysemy and brevity versus frequency in language 

    Casas Fernández, Bernardino; Hernández Fernández, Antonio; Catala Roig, Neus; Ferrer Cancho, Ramon; Baixeries i Juvillà, Jaume (Elsevier, 2019-11-01)
    Artículo
    Acceso abierto
    The pioneering research of G. K. Zipf on the relationship between word frequency and other word features led to the formulation of various linguistic laws. The most popular is Zipf’s law for word frequencies. Here we focus ...

  • Generalized satisfiability problems via operator assignments 

    Atserias, Albert; Kolaitis, Phokion; Severini, Simone (2019-05-21)
    Artículo
    Acceso abierto
    Schaefer introduced a framework for generalized satisfiability problems on the Boolean domain and characterized the computational complexity of such problems. We investigate an algebraization of Schaefer's framework in ...
