DAMA-UPC - Data Management Group de la Universitat Politècnica de Catalunya

 

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.

    Open Access
    The urban parking spaces for loading/unloading are typically over-occupied, which shifts delivery operations to traffic lanes and pavements, increases traffic, generates noise, and causes pollution. We present a data ...

  • 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
    Open Access
    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
    Open Access
    Database schemas and user queries are continuously growing with the need for storing and accessing large amounts of structured information. Among the several proposals to deal with Large Join Query Problem, genetic optimizers ...

  • Marshall-Olkin extended Zipf distribution 

    Pérez Casany, Marta; Duarte López, Ariel; Prat Pérez, Arnau (Springer, 2015-12-18)
    Part of book or chapter of book
    Open Access
    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 ...
