  • The probabilistic p-center problem: Planning service for potential customers 

    Martínez Merino, Luisa I.; Albareda Sambola, Maria; Rodríguez Chía, Antonio Manuel (Elsevier, 2017-10-16)
    Article
    Accés restringit per política de l'editorial
    This work deals with the probabilistic p-center problem, which aims at minimizing the expected maximum distance between any site with demand and its center, considering that each site has demand with a specific probability. ...
  • Another look at principal curves and surfaces 

    Delicado Useros, Pedro Francisco (2001-03)
    Article
    Accés obert
    Principal curves have been defined as smooth curves passing through the “middle” of a multidimensional data set. They are nonlinear generalizations of the first principal component, a characterization of which is the basis ...
  • Influence of data resolution in nonlinear loads model for harmonics prediction 

    Balcells Sendra, Josep; Lamich Arocas, Manuel; Griful Ponsati, Eulàlia; Corbalán Fuertes, Montserrat (2016)
    Article
    Accés obert
    This paper describes the influence of data resolution in the agreement of models to predict harmonics generated by nonlinear loads (NLL), basically formed by single phase and three phase rectifiers, eventually combined ...
  • Load-sharing policies in parallel simulation of agent-based demographic models 

    Pellegrini, Alessandro; Montañola Sales, Cristina; Quaglia, Francesco; Casanovas Garcia, Josep (2017)
    Article
    Accés obert
    Execution parallelism in agent-Based Simulation (ABS) allows to deal with complex/large-scale models. This raises the need for runtime environments able to fully exploit hardware parallelism, while jointly offering ABS-suited ...
  • Contagion between United States and european markets during the recent crises 

    Muñoz Gracia, María del Pilar; Márquez Cebrián, Dolores; Sánchez Espigares, Josep Anton (2011-07)
    Article
    Accés obert
    The main objective of this paper is to detect the existence of financial contagion between the North American and European markets during the recent crises. To accomplish this, the relationships between the US and the Euro ...
  • Exploring link covering and node covering formulations of detection layout problem 

    Barceló Bugeda, Jaime; Gilliéron, Fanny; Linares Herreros, Mª Paz; Serch Muni, Oriol; Montero Mercadé, Lídia (2012-02)
    Article
    Accés obert
    The primary data input used in principal traffic models comes from Origin-Destination (OD) trip matrices, which describe the patterns of traffic behavior across the network. In this way, OD matrices become a critical ...
  • Use of results from honing test machines to determine roughness in industrial honing machines 

    Buj Corral, Irene; Rodero de Lamo, Lourdes; Marco Almagro, Lluís (Elsevier Ltd, 2017-08-01)
    Article
    Accés restringit per política de l'editorial
    In the present work, a new methodology is presented to translate roughness results from a test machine to different industrial machines without the need to stop production for a long time. First, mathematical models were ...
  • Impact of protease inhibitors on the evolution of urinary markers: subanalyses from an observational cross-sectional study 

    Bonjoch Badia, Anna; Puig, Jordi; Pérez Álvarez, Nuria; Juega Mariño, Javier; Echeverria Liras, Patricia; Clotet Sala, Bonaventura; Romero, Ramon; Bonet, Josep; Negredo Puigmal, Eugènia (2016-08)
    Article
    Accés obert
    Kidney injury (defined as the presence of albuminuria, proteinuria, glycosuria [without hyperglycemia], hematuria, and/or renal hypophosphatemia) is an emerging problem in human immunodeficiency virus (HIV)-infected patients, ...
  • Prospective study to assess progression of renal markers after interruption of tenofovir due to nephrotoxicity 

    Bonjoch Badia, Anna; Echeverria Liras, Patricia; Pérez Álvarez, Nuria; Puig, Jordi; Estany Quera, Carla; Clotet Sala, Bonaventura; Negredo Puigmal, Eugènia (2016)
    Article
    Accés obert
    Background. Prospective studies about the reversibility of tenofovir disoproxil fumarate- (TDF-) related renal impairment remain scarce. Methods. This is an observational prospective study including all patients that ...
  • Simulation model to find the best comfort, energy and cost scenarios for building refurbishment 

    Fonseca Casas, Antoni; Ortiz, Joana Aina; Garrido Soriano, Núria; Fonseca Casas, Pau; Salom Tormo, Jaume (2017-05-12)
    Article
    Accés restringit per política de l'editorial
    This article proposes a methodology to assess building behaviour, whilst taking its life cycle into account. Understanding of the system can be obtained by combining well-known energy consumption calculation engines (TRNSYS) ...
