  • Internationalization of R&D in two high-tech clusters and cooperation of R&D units in those clusters 

    Štrukelj, Peter; Dolinšek, Slavko (School of Industrial and Aeronautic Engineering of Terrassa (ETSEIAT). Universitat Politècnica de Catalunya (UPC), 2010-10)
    Article
    Open Access
    In the paper, we present how transnational corporations (TNCs) internationalize their R&D and how they allocate foreign R&D units in high-tech clusters, where competitors of these TNCs, research and academic institutions, ...
  • Non-parametric document clustering by ensemble methods 

    González Pellicer, Edgar; Turmo Borras, Jorge (2008-03)
    Article
    Open Access
    Los sesgos de los algoritmos individuales para clustering no paramétrico de documentos pueden conducir a soluciones no óptimas. Los métodos de consenso podrían compensar esta limitación, pero no han sido probados sobre ...
