    Modern SAT solvers have experienced a remarkable progress on solving industrial instances. It is believed that most of these successful techniques exploit the underlying structure of industrial instances. Recently, there ...
  • Correlations in the organization of large-scale syntactic dependency networks 

    Ferrer Cancho, Ramon; Mehler, Alexander; Pustylnikov, Olga; Díaz Guilera, Albert (Association for Computational Linguistics, 2007)
    Conference report
    Open Access
    We study the correlations in the connectivity patterns of large scale syntactic dependency networks. These networks are induced from treebanks: their vertices denote word forms which occur as nuclei of dependency trees. ...
  • When language breaks into pieces: A conflict between communication through isolated signals and language 

    Ferrer Cancho, Ramon (2005)
    Conference lecture
    Open Access
    Here we study a communication model where signals associate to stimuli. The model assumes that signals follow Zipf’s law and the exponent of the law depends on a balance between maximizing the information transfer and ...
  • A Web-based application for the visual exploration of colon morphology data 

    Males, Jan; Monclús Lahoya, Eva; Díaz Iriberri, José; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2019)
    Conference report
    Open Access
    The colon is an organ whose constant motility poses difficulties to its analysis. Although morphological data can be successfully extracted from Computational Tomography, its radiative nature makes it only indicated for ...
  • Colonic content assessment from MRI imaging using a semi-automatic approach 

    Ceballos Inza, Víctor; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Bendezú García, Álvaro; Mego Silva, Marianela; Merino Casabiel, Xavier; Azpiroz Vidaur, Fernando; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2019)
    Conference report
    Open Access
    The analysis of the morphology and content of the gut is necessary in order to achieve a better understanding of its metabolic and functional activity. Magnetic resonance imaging (MRI) has become an important imaging ...

    Conference report
    Open Access
    Context: Software evolution ensures that software systems in use stay up to date and provide value for end-users. However, it is challenging for requirements engineers to continuously elicit needs for systems used by ...
  • Enhancing federated cloud management with an integrated service monitoring approach 

    Kertész, Attila; Kecskemeti, Gabor; Oriol Hilari, Marc; Kotcauer, Péter; Acs, Sandor; Rodríguez Navarro, Marc; Mercè Pont, Oscar; Marosi, Csaba Attila; Marco Gómez, Jordi; Franch Gutiérrez, Javier (2013-12)
    Article
    Open Access
    Cloud Computing enables the construction and the provisioning of virtualized service-based applications in a simple and cost effective outsourcing to dynamic service environments. Cloud Federations envisage a distributed, ...
  • Building and using quality models for complex software domains 

    Carvallo Vega, Juan Pablo; Franch Gutiérrez, Javier; Quer, Carme (2003)
    External research report
    Open Access
    The use of quality models in software package procurement provides a framework for the description of the domain which the package belongs to. Package descriptions and user quality requirements may be translated into the ...
  • Goal and variability modeling for service-oriented system: Integrating i* with decision models 

    Grünbacher, Paul; Dhungana, Deepak; Seyff, Norbert; Quintus, Michael; Clotet Martínez, Roger; Franch Gutiérrez, Javier; López Cuesta, Lidia; Marco Gómez, Jordi (Helsinki University of Technology, 2007)
    Conference lecture

    Variability modeling and service-orientation are important approaches that address both the flexibility and adaptability required by stakeholders of today’s software systems. Goal-oriented approaches for modeling ...
  • Algebraic definition of iStar2.0 models 

    Franch Gutiérrez, Javier; López Cuesta, Lidia; Marco Gómez, Jordi (CEUR-WS.org, 2019)
    Conference report
    Open Access
    iStar2.0 was delivered in 2016 with the intention of becoming a standard de facto for the i* community. It includes a lightweight definition of the language adorned with a metamodel (in the form of a UML class diagram) ...
  • Enhanced equal frequency partition method for the identification of a water demand system 

    Escobet Canal, Antoni; Huber Garrido, Rafael M.; Nebot Castells, M. Àngela; Cellier, François E. (Sarjoughian,H.S.; Cellier, F.E.; Marefat, M.M.; Rozenblit, J.W. (eds.) Institute of Electrical and Electronics Engineers, 2000)
    Conference report
    Open Access
    This paper deals with unsupervised partitioning. A first goal of this paper is to present an enhancement to the Equal Frequency Partition (EFP) method that allows to reduce, to some extent, the main drawback of this classical ...
