El grup DAMA-UPC s'especialitza en la gestió de grans volums de dades amb especial èmfasi en el rendiment i la qualitat de les dades. Té en compte les necessitats del kernel de la base de dades, centrant-se especialment en l'optimitzador i el motor d'execució, o el repositori de dades bàsic ubicat per sobre del sistema de fitxers del SO. Les seves habilitats permeten la millora del rendiment en aplicacions executades amb les dades en memòria i en aplicacions executades amb les dades a disc.

DAMA-UPC és membre de la Xarxa IT pertanyent al Departament d'Industria de la Generalitat de Catalunya des del començament del 2005.

  • What does a zero mean? understanding false, random and structural zeros in ecology 

    Blasco Moreno, Anabel; Pérez Casany, Marta; Puig, Pedro; Morante, Maria; Castells, Eva (2019-03-27)
    Article
    Restricted access - publisher's policy
    1. Zeros (i.e. events that do not happen) are the source of two common phenomena in count data: overdispersion and zero-inflation. Zeros have multiple origins in a dataset: false zeros occur due to errors in the experimental ...
  • 3D-PP: A tool for discovering conserved three-dimensional protein patterns 

    Valdés Jiménez, Alejandro; Larriba Pey, Josep; Núñez Vivanco, Gabriel; Reyes Parada, Miguel (2019-06-28)
    Article
    Open Access
    Discovering conserved three-dimensional (3D) patterns among protein structures may provide valuable insights into protein classification, functional annotations or the rational design of multi-target drugs. Thus, several ...
  • Intensive crossovers: Improving quality in a genetic query optimizer 

    Muntés Mulero, Víctor; Aguilar Saborit, Josep; Zuzarte, Calisto; Larriba Pey, Josep (International Centre for Numerical Methods in Engineering (CIMNE), 2006)
    Conference report
