  • Automated construction and analysis of political networks via open government and media sources 

    García-Olano, Diego; Arias Vicente, Marta; Larriba Pey, Josep (2016)
    Text en actes de congrés
    Accés obert
    We present a tool to generate real world political networks from user provided lists of politicians and news sites. Additional output includes visualizations, interactive tools and maps that allow a user to better understand ...
  • Exploiting path parallelism in logic programming 

    Tubella Murgadas, Jordi; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 1995)
    Text en actes de congrés
    Accés obert
    This paper presents a novel parallel implementation of Prolog. The system is based on Multipath, a novel execution model for Prolog that implements a partial breadth-first search of the SLD-tree. The paper focusses on the ...
  • A methodology for user-oriented scalability analysis 

    Royo Vallés, María Dolores; Valero García, Miguel; González Colás, Antonio María; Marí, Carme (Institute of Electrical and Electronics Engineers (IEEE), 1997)
    Text en actes de congrés
    Accés obert
    Scalability analysis provides information about the effectiveness of increasing the number of resources of a parallel system. Several methods have been proposed which use different approaches to provide this information. ...
  • A Jacobi-based algorithm for computing symmetric eigenvalues and eigenvectors in a two-dimensional mesh 

    Royo Vallés, María Dolores; Valero García, Miguel; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Text en actes de congrés
    Accés obert
    The paper proposes an algorithm for computing symmetric eigenvalues and eigenvectors that uses a one-sided Jacobi approach and is targeted to a multicomputer in which nodes can be arranged as a two-dimensional mesh with ...
  • On the use of the derivative of the pole trajectories of the LPC analysis parameter sequence as an alternative to delta parameters 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (ESCA - J.M. PARDO, E. ENRIQUEZ, J. ORTEGA, J. FERREIROS GTM-UPM, 1995)
    Text en actes de congrés
    Accés obert
    In this paper a new approach for modelling time variations in the speech spectra is presented. We propose to approximate the trajectories of the frequency and amplitude of the poles of the LPC spectra with exponential ...
  • An efficient solver for Cache Miss Equations 

    Bermudo, Nerina; Vera Rivera, Francisco Javier; González Colás, Antonio María; Llosa Espuny, José Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Text en actes de congrés
    Accés obert
    Cache Miss Equations (CME) (S. Ghosh et al., 1997) is a method that accurately describes the cache behavior by means of polyhedra. Even though the computation cost of generating CME is a linear function of the number of ...
  • A quantitative assessment of thread-level speculation techniques 

    Marcuello Pascual, Pedro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Text en actes de congrés
    Accés obert
    Speculative thread-level parallelism has been recently proposed as an alternative source of parallelism that can boost the performance for applications where independent threads are hard to find. Several schemes to exploit ...
  • Near-optimal loop tiling by means of cache miss equations and genetic algorithms 

    Abella Ferrer, Jaume; González Colás, Antonio María; Llosa Espuny, José Francisco; Vera Rivera, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2002)
    Text en actes de congrés
    Accés obert
    The effectiveness of the memory hierarchy is critical for the performance of current processors. The performance of the memory hierarchy can be improved by means of program transformations such as loop tiling, which is a ...
  • Effects of En-route Wake Vortex on RPAS Operations 

    Pérez Batlle, Marcos; Marcos, Mònica; Pastor Llorens, Enric (2016)
    Text en actes de congrés
    Accés obert
    Compared with common airliners, High/Medium Altitude Long Endurance (HALE/MALE) RPAS are lighter and have larger wingspan. Therefore RPAS will be extremely sensitive to vortex interactions with larger airliners, not ...
  • High-Performance low-vcc in-order core 

    Abella Ferrer, Jaume; Chaparro, Pedro; Vera Rivera, Francisco Javier; Carretero Casado, Javier; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Text en actes de congrés
    Accés obert
    Power density grows in new technology nodes, thus requiring Vcc to scale especially in mobile platforms where energy is critical. This paper presents a novel approach to decrease Vcc while keeping operating frequency high. ...
