  • A conflict-free memory banking architecture for fast VOQ packet buffers 

    García Vidal, Jorge; Cerdà Alabern, Llorenç; Corbal San Adrián, Jesús; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    Text en actes de congrés
    Accés obert
    In order to support the enormous growth of the Internet, innovative research in every router subsystem is needed. We focus our attention on packet buffer design for routers supporting high-speed line rates. More specifically, ...
  • Rainbow spanning subgraphs in bounded edge–colourings of graphs with large minimum degree 

    Cano Vila, María del Pilar; Perarnau Llobet, Guillem; Serra Albó, Oriol (2017-08-01)
    Article
    Accés restringit per política de l'editorial
    We study the existence of rainbow perfect matching and rainbow Hamiltonian cycles in edge–colored graphs where every color appears a bounded number of times. We derive asymptotically tight bounds on the minimum degree of ...
  • On sets defining few ordinary planes 

    Ball, Simeon Michael (2017-09-19)
    Article
    Accés restringit per política de l'editorial
    Let S be a set of n points in real three-dimensional space, no three collinear and not all co-planar. We prove that if the number of planes incident with exactly three points of S is less than (Formula presented.) for some ...
  • On the design of hybrid DRAM/SRAM memory schemes for fast packet buffers 

    García Vidal, Jorge; March Hermo, María Isabel; Cerdà Alabern, Llorenç; Corbal San Adrián, Jesús; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2004)
    Text en actes de congrés
    Accés obert
    We address the design of a packet buffer for future high-speed routers that support line rates as high as OC-3072 (160 Gb/s), and a high number of ports and service classes. We describe a general design for hybrid DRAM/SRAM ...
  • Grinding-induced metallurgical alterations in the binder phase of WC-Co cemented carbides 

    Yang, Jing; Roa Rovira, Joan Josep; Schwind, Martin; Odén, M.; Johansonn Joesaar, M. P.; Llanes Pitarch, Luis Miguel (2017-12)
    Article
    Accés obert
    The metallic binder phase dictates the toughening behavior of WC-Co cemented carbides (hardmetals), even though it occupies a relative small fraction of the composite. Studies on deformation and phase transformation of the ...
  • Numerical study of an impulse wave generated by a sliding mass 

    Schillaci, Eugenio; Favre Samarra, Federico; Antepara Zambrano, Óscar; Balcazar, Nestor; Oliva Llena, Asensio (WIT Press, 2018)
    Article
    Accés obert
    In this work, a numerical framework for the direct numerical simulation of tsunami waves generated by landslide events is proposed. The method, implemented on the TermoFluids numerical platform, adopts a free surface model ...
  • Multi-model assessment of linkages between eastern Arctic sea-ice variability and the Euro-Atlantic atmospheric circulation in current climate 

    García-Serrano, Javier; Frankignoul, C.; King, M.P.; Arribas, A.; Gao, Y.; Guemas, Virginie; Matei, D.; Msadek, R.; Park, W.; Sanchez-Gomenez, E. (Springer, 2017-10)
    Article
    Accés restringit per política de l'editorial
    A set of ensemble integrations from the Coupled Model Intercomparison Project phase 5, with historical forcing plus RCP4.5 scenario, are used to explore if state-of-the-art climate models are able to simulate previously ...
  • Efficient CFD code implementation for the ARM-based Mont-Blanc architecture 

    Oyarzun, G.; Borrell, Ricard; Gorobets, A.; Mantovani, Filippo; Oliva, A. (Elsevier, 2018-02)
    Article
    Accés obert
    Since 2011, the European project Mont-Blanc has been focused on enabling ARM-based technology for HPC, developing both hardware platforms and system software. The latest Mont-Blanc prototypes use system-on-chip (SoC) devices ...
  • Aerosol-radiation interaction in atmospheric models: Idealized sensitivity study of simulated short-wave direct radiative effects to particle microphysical properties 

    Obiso, Vincenzo; Jorba, Oriol (Elsevier, 2018-01)
    Article
    Accés obert
    We assessed the impact of the microphysical parameterization of natural and anthropogenic aerosols on simulated short-wave radiative effects due to Aerosol-Radiation Interaction (ARI). Layer radiative properties (optical ...
  • Low-temperature colloidal synthesis of CuBiS2 nanocrystals for optoelectronic devices 

    Wang, Jian-Jun; Akgul, Zafer; Bi, Yu; Christodouloua, Sotirios; Konstantatos, Gerasimos (Royal Society of Chemistry, 2017-11-11)
    Article
    Accés restringit per política de l'editorial
    A new facile colloidal synthesis of CuBiS2 (CBS) nanocrystals with monodispersed size and good quality has been developed. The CBS nanocrystal films was deposited by solid-state ligand exchange and their field effect ...
