  • A formal method for conceptual fit analysis 

    Olivé Ramon, Antoni (2016-01)
    Article
    Open Access
    One criterion that has received little attention in COTS systems selection is what we call conceptual fit. The criterion assesses the fit between the conceptual structure of the user requirements and that of a candidate ...
  • Incremental consolidation of data-intensive multi-flows 

    Jovanovic, Petar; Romero Moral, Óscar; Simitsis, Alkis; Abelló Gamazo, Alberto (2016-05-01)
    Article
    Open Access
    Business intelligence (BI) systems depend on efficient integration of disparate and often heterogeneous data. The integration of data is governed by data-intensive flows and is driven by a set of information requirements. ...
  • Towards a generic benchmarking platform for origin–destination flows estimation/updating algorithms: design, demonstration and validation 

    Antoniou, Constantinos; Barceló Bugeda, Jaime; Breen, Martijn; Bullejos, Manuel; Casas, Jordi; Cipriani, Ernesto; Ciuffo, Biagio; Djukic, Tamara; Hoogendoorn, Serge; Marzano, Vittorio; Montero Mercadé, Lídia; Nigro, Marialisa; Perarnau, Josep; Punzo, Vincenzo; Toledo, Tomer; van Lint, Hans (2016-05-01)
    Article

    Estimation/updating of origin-destination (OD) flows and other traffic state parameters is a classical, widely adopted procedure in transport engineering, both in off-line and in on-line contexts. Notwithstanding numerous ...
  • Coloured Petri net-based traffic collision avoidance system encounter model for the analysis of potential induced collisions 

    Tang, Jun; Piera, Miquel Angel; Guasch Petit, Antonio (2016-03-03)
    Article
    Open Access
    The Traffic Alert and Collision Avoidance System (TCAS) is a world-wide accepted lastresort means of reducing the probability and frequency of mid-air collisions between aircraft. Unfortunately, it is widely known that in ...
  • Individual-based modeling of tuberculosis in a user-friendly interface: Understanding the epidemiological role of population heterogeneity in a city 

    Prats Soler, Clara; Montañola Sales, Cristina; Gilabert Navarro, Joan-Francesc; Valls Ribas, Joaquim; Casanovas Garcia, Josep; Vilaplana, Cristina; Cardona Iglesias, Pere Joan; López Codina, Daniel (2016-01-01)
    Article
    Open Access
    © 2016 Prats, Montañola-Sales, Gilabert-Navarro, Valls, Casanovas-Garcia, Vilaplana, Cardona and López. For millennia tuberculosis (TB) has shown a successful strategy to survive, making it one of the world's deadliest ...
  • Computing repairs for constraint violations in UML/OCL conceptual schemas 

    Oriol Hilari, Xavier; Teniente López, Ernest; Tort, Albert (Elsevier, 2015-06-25)
    Article
    Restricted access - publisher's policy
    Updating the contents of an information base may violate some of the constraints defined over the schema. The classical way to deal with this problem has been to reject the requested update when its application would lead ...
  • A robust framework for the estimation of dynamic OD trip matrices for reliable traffic management 

    Barceló Bugeda, Jaime; Montero Mercadé, Lídia (Elsevier, 2015)
    Article
    Open Access
    Origin-Destination (OD) trip matrices describe the patterns of traffic behavior across the network and play a key role as primary data input to many traffic models. OD matrices are a critical requirement, either in static ...
  • Ontology-based mappings 

    Mecca, Giansalvatore; Rull, Guillem; Santoro, Donatello; Teniente López, Ernest (Elsevier, 2015-07-01)
    Article
    Restricted access - publisher's policy
    Data translation consists of the task of moving data from a source database to a target database. This task is usually performed by developing mappings, i.e. executable transformations from the source to the target schema. ...
  • Applying projection-based methods to the asymmetric traffic assignment problem 

    Codina Sancho, Esteve; Ibáñez Marí, Gemma; Barceló Bugeda, Jaime (2015-02-01)
    Article
    Open Access
    This article examines the application of a path-based algorithm to the static and fixed demand asymmetric traffic assignment problem. The algorithm is of the simplicial decomposition type and it solves the equilibration ...
  • Improving prevalence estimation through data fusion: methods and validation 

    Aluja Banet, Tomàs; Daunis Estadella, Josep; Brunsó, Núria; Mompart Penina, Anna (2015-06-24)
    Article
    Open Access
    Estimation of health prevalences is usually performed with a single survey. Some attempts have been made to integrate more than one source of data. We propose here to validate this approach through data fusion. Data Fusion ...
