    Community networks are self-organized and decentralized communication networks built and operated by citizens, for citizens. The consolidation of today's cloud technologies offers now, for community networks, the possibility ...
  • Mobile Autonomous Sensing Unit (MASU): a framework that supports distributed pervasive data sensing 

    Medina Medina, Esunly; López Nuevo, David Andrés; Meseguer Pallarès, Roc; Ochoa, Sergio; Royo Vallés, María Dolores; Santos, Rodrigo (2016-07)
    Article
    Open Access
    Pervasive data sensing is a major issue that transverses various research areas and application domains. It allows identifying people’s behaviour and patterns without overwhelming the monitored persons. Although there are ...
  • Ponderación ML de parámetros en un sistema de reconocimiento de palabras basado en CDHMM 

    Valverde Amador, Antonio Javier; Hernando Pericás, Francisco Javier; Nogueiras Rodríguez, Albino (1996)
    Conference lecture
    Open Access
    Speech dynamic feature are routinely used in current speech recognition systems in combination with short-term (static) spectral features. The aim of this paper is to propose a method to automatically estimate the optimum ...
  • Experimental demonstration of multi-vendor and multi-domain elastic optical network with data and control interoperability over a pan-european test-bed 

    González de Dios, Oscar; Casellas Regi, Ramón; Paolucci, Francesco; Napoli, Antonio; Gifre Renom, Lluís; Dupas, Arnaud; Hugues Salas, Emilio; Morro, Roberto; Belotti, Sergio; Meloni, Gianluca; Rahman, Talha; López Álvarez, Victor; Martínez Rivera, Ricardo Victor; Fresi, Francesco; Bohn, Marc; Yan, Shuangyi; Velasco Esteban, Luis Domingo; Layec, Patricia; Fernández Palacios, Juan Pedro (2016-04-01)
    Article
    Open Access
    The operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended ...
  • Area model and dimensioning guidelines of multisource energy harvesting for nano-micro interface 

    Gomez Cid-Fuentes, Raül; Cabellos Aparicio, Alberto; Alarcón Cot, Eduardo José (2016-02-01)
    Article
    Open Access
    Multisource energy harvesters are a promising, robust alternative to power the future Internet of Nano Things (IoNT), since the network elements can maintain their operation regardless of the fact that one of its energy ...
  • Modelado de la trayectoria de los polos en la secuencia de LPC 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (Universidad de Valladolid, 1995)
    Conference report
    Open Access
    A alternative way of representing time variations of the speech spectra is presented. We propose to model the trajectories of the poles of the LPC analysis spectra using exponential functions as alternative to delta ...
  • On the use of the derivative of pole trajectories of the LPC analysis parameter sequence as an alternative to delta parameters 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (1995)
    Conference report
    Open Access
    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 ...
  • Evaluating the impact of OpenMP 4.0 extensions on relevant parallel workloads 

    Vidal Ortiz, Raul; Casas Guix, Marc; Moreto Planas, Miquel; Chasapis, Dimitrios; Ferrer Ibáñez, Roger; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Springer, 2015)
    Conference report

    OpenMP has been for many years the most widely used programming model for shared memory architectures. Periodically, new features are proposed and some of them are finally selected for inclusion in the OpenMP standard. The ...
  • Sensible energy accounting with abstract metering for multicore systems 

    Liu, Qixiao; Moreto Planas, Miquel; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier; Jiménez, Daniel A.; Valero Cortés, Mateo (2016-01)
    Article
    Open Access
    Chip multicore processors (CMPs) are the preferred processing platform across different domains such as data centers, real-time systems, and mobile devices. In all those domains, energy is arguably the most expensive ...
  • Runtime-guided management of scratchpad memories in multicore architectures 

    Álvarez Martí, Lluc; Moreto Planas, Miquel; Casas Guix, Marc; Castillo Villar, Emilio; Martorell Bofill, Xavier; Labarta Mancho, Jesús José; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    The increasing number of cores and the anticipated level of heterogeneity in upcoming multicore architectures cause important problems in traditional cache hierarchies. A good way to alleviate these problems is to add ...
