  • Cache-aware load balancing vs. cooperative caching for distributed search engines 

    Domínguez Sal, David; Pérez Casany, Marta; Larriba Pey, Josep (IEEE Computer Society Publications, 2009-06-25)
    Text en actes de congrés
    Accés obert
    In this paper we study the performance of a distributed search engine from a data caching point of view. We compare and combine two different approaches to achieve better hit rates: (a) send the queries to the node which ...

  • Cooperative cache analysis for distributed search engines 

    Domínguez Sal, David; Pérez Casany, Marta; Larriba Pey, Josep (2010)
    Article
    Accés restringit per política de l'editorial
    In this paper, we study the performance of a distributed search engine from a data caching point of view using statistical tools on a varied set of configurations. We study two strategies to achieve better performance: ...

  • Marshall-Olkin extended Zipf distribution 

    Pérez Casany, Marta; Duarte López, Ariel; Prat Pérez, Arnau (Springer, 2015-12-18)
    Capítol de llibre
    Accés obert
    Being able to generate large synthetic graphs resembling those found in the real world, is of high importance for the design of new graph algorithms and benchmarks. In this paper, we first compare several probability models ...

  • On left-truncating and mixing poisson distributions 

    Valero Baya, Jordi; Pérez Casany, Marta; Ginebra Molins, Josep (2014-02-01)
    Article
    Accés obert
    The distributions obtained by left-truncating at k a mixed Poisson distribution, kT-MP, and those obtained by mixing previously left-truncated Poisson distributions, M-kTP, are characterized by means of their probability ...

  • On poisson-stopped-sums that are mixed poisson 

    Valero Baya, Jordi; Pérez Casany, Marta; Ginebra Molins, Josep (2013)
    Article
    Accés restringit per política de l'editorial
    Maceda (1948) characterized the mixed Poisson distributions that are Poisson-stopped-sum distributions based on the mixing distribution. In an alternative characterization of the same set of distributions here the ...

  • The CHARME "Advanced Big Data Training School for Life Sciences": an example of good practices for training on current bioinformatics challenges 

    Hoang, Yen; Pfeil, Juliane; Zagoršcak, Maja; Zdravevski, Eftim; Ramšak, Živa; Schulze, Sabrina K.; Papageorgiou, K.; Duarte López, Ariel; Pérez Casany, Marta (2019-02-05)
    Article
    Accés obert
    The CHARME “Advanced Big Data Training School for Life Sciences” took place during 3-7 September 2018, at the Campus Nord of the Technical University of Catalonia (UPC) in Barcelona (ES). The school was organised by the ...
