  • Design of a flight management system to support four-dimensional trajectories 

    Amaro Carmona, Manuel Angel; Rudinskas, Darius; Barrado Muxí, Cristina (2015-03-01)
    Article
    Open Access
    This paper presents the design and simulation of the functions of a flight Management System (FMS) in order to follow four-dimensional trajectories automatically. This is achieved by controlling the aircraft’s airspeed, ...
  • Quality of network economics optimisation using service level agreement modelling 

    Santos Boada, Germán; Amazonas, José Roberto de Almeida; Solé Pareta, Josep (Wiley-Blackwell, 2016-02-09)
    Article

    The scalability of Network-on-Chip (NoC) designs has become a rising concern as we enter the manycore era. Multicast support represents a particular yet relevant case within this context, mainly due to the poor performance ...
  • Compact finite difference modeling of 2-D acoustic wave propagation 

    Córdova, Luis; Rojas, Otilio; Otero Calviño, Beatriz; Castillo, Jose (2016-03-15)
    Article
    Open Access
    We present two fourth-order compact finite difference (CFD) discretizations of the velocity–pressure formulation of the acoustic wave equation in 2-D rectangular grids. The first method uses standard implicit CFD on nodal ...
  • Cost-conscious strategies to increase performance of numerical programs on agressive VLIW architectures 

    López Álvarez, David; Llosa Espuny, José Francisco; Valero Cortés, Mateo; Ayguadé Parra, Eduard (2001-10)
    Article
    Open Access
    Loops are the main time-consuming part of numerical applications. The performance of the loops is limited either by the resources offered by the architecture or by recurrences in the computation. To execute more operations ...
  • Thread assignment of multithreaded network applications in multicore/multithreaded processors 

    Radojkovic, Petar; Cakarevic, Vladimir; Verdú Mulà, Javier; Pajuelo González, Manuel Alejandro; Cazorla Almeida, Francisco Javier; Nemirovsky, Mario; Valero Cortés, Mateo (2013-12)
    Article
    Open Access
    The introduction of multithreaded processors comprised of a large number of cores with many shared resources makes thread scheduling, and in particular optimal assignment of running threads to processor hardware contexts ...
  • An autonomic traffic classification system for network operation and management
