    Speech is a rich biometric signal that contains information about the identity, gender and emotional state of the speaker. In this work, we explore its potential to generate face images of a speaker by conditioning a ...

  • Collaborative informed gateway selection in large-scale and heterogeneous 

    Batbayar, Khulan; Dimogerontakis, Emmanouil; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Sadre, Ramin (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report

    In wireless community access networks, clients tend to reach the Internet through multiple gateway nodes instead of a single default gateway. The mapping of gateways to clients should take into account the perception of ...

  • PROFET: modeling system performance and energy without simulating the CPU 

    Radulovic, Milan; Sánchez-Verdejo, Rommel; Carpenter, Paul Matthew; Radojkovic, Petar; Jacob, Bruce; Ayguadé Parra, Eduard (2019-06)
    Article
    Open Access
    The approaching end of DRAM scaling and expansion of emerging memory technologies is motivating a lot of research in future memory systems. Novel memory systems are typically explored by hardware simulators that are slow ...

  • IPchain: securing IP prefix allocation and delegation with blockchain 

    Paillissé Vilanova, Jordi; Ferriol Galmés, Miquel; Garcia Ribera, Eric; Lafif Martínez, Hamid; Piris Yamuza, Carlos; López Brescó, Albert; Cabellos Aparicio, Alberto
    Conference report
    Restricted access - publisher's policy
    We present IPchain, a blockchain to store the allocations and delegations of IP addresses, with the aim of easing the deployment of secure interdomain routing systems. Interdomain routing security is of vital importance ...

  • Data conversion in area-constrained applications: the wireless network-on-chip case 

    Abadal Cavallé, Sergi; Alarcón Cot, Eduardo José
    Conference report
    Restricted access - publisher's policy
    Network-on-Chip (NoC) is currently the paradigm of choice to interconnect the different components of System-on-Chips (SoCs) or Chip Multiprocessors (CMPs). As the levels of integration continue to grow, however, current ...

  • CIPSEC-Enhancing Critical Infrastructure Protection with Innovative Security Framework 

    Marín Tordera, Eva; Masip Bruin, Xavier; Forné Muñoz, Jorge (River Publishers, 2019-07-22)
    Part of book or chapter of book
    Restricted access - publisher's policy
    In the recent years, the majority of the world’s Critical Infrastructures (CIs) have evolved to be more flexible, cost efficient and able to offer better services and conditions for business growth. Through this evolution, ...

  • Time series analysis to predict end-to-end quality of wireless community networks 

    Millán Marco, Pere; Aliagas Castell, Carles; Molina Clemente, Carlos Maria; Dimogerontakis, Emmanouil; Meseguer Pallarès, Roc (2019-05-01)
    Article
    Open Access
    Community Networks have been around us for decades being initially deployed in the USA and Europe. They were designed by individuals to provide open and free “do it yourself” Internet access to other individuals in the ...

  • Application Acceleration on FPGAs with OmpSs@FPGA 

    Bosch, Jaume; Tan, Xubin; Filgueras Izquierdo, Antonio; Vidal, Miquel; Mateu, Marc; Jiménez-González, Daniel; Álvarez, Carlos; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    OmpSs@FPGA is the flavor of OmpSs that allows offloading application functionality to FPGAs. Similarly to OpenMP, it is based on compiler directives. While the OpenMP specification also includes support for heterogeneous ...

  • Increasing the number of strides for conflict-free vector access 

    Valero Cortés, Mateo; Lang, Tomas; Llaberia Griñó, José M.; Peiron Guàrdia, Montse; Ayguadé Parra, Eduard; Navarro Guerrero, Juan José (1992-05)
    Article
    Open Access
    Address transformation schemes, such as skewing and linear transformations, have been proposed to achieve conflict-free vector access for some strides in vector processors with multi-module memories. In this paper, we ...

  • Conflict-free strides for vectors in matched memories 

    Valero Cortés, Mateo; Lang, Tomas; Llaberia Griñó, José M.; Peiron Guàrdia, Montse; Navarro Guerrero, Juan José; Ayguadé Parra, Eduard (1991-12)
    Article
