    Article
    Accés restringit per política de l'editorial
    In this paper, we present a new automatic screening method to assess whether a patient from ambulatory care or emergency should be referred to a cardiology service. This method is based on deep neural networks with pretraining ...
  • Learning definite Horn formulas from closure queries 

    Arias Vicente, Marta; Balcázar Navarro, José Luis; Tîrnauca, Cristina (2017-01-07)
    Article
    Accés obert
    A definite Horn theory is a set of n-dimensional Boolean vectors whose characteristic function is expressible as a definite Horn formula, that is, as conjunction of definite Horn clauses. The class of definite Horn theories ...

  • A model for providing emotion awareness and feedback using fuzzy logic in online learning 

    Arguedas, Marta; Xhafa Xhafa, Fatos; Casillas, Luis; Daradoumis, Thanasis; Peña, Adriana; Caballé Llobet, Santiago (Springer, 2016-10-20)
    Article
    Accés restringit per política de l'editorial
    Monitoring users’ emotive states and using that information for providing feedback and scaffolding is crucial. In the learning context, emotions can be used to increase students’ attention as well as to improve memory and ...
  • Generalising discontinuity 

    Morrill, Glyn; Merenciano Saladrigas, Josep Maria (1996-01)
    Report de recerca
    Accés obert
    This paper makes two generalisations of categorial calculus of discontinuity. In the first we introduce unary modalities which mediate between continuous and discontinuous strings. In the second each of the modes of ...
  • Quasipolynomial size frege proofs of Frankl's Theorem on the trace of sets 

    Aisenberg, James; Bonet Carbonell, M. Luisa; Buss, Sam (2016-06-01)
    Article
    Accés obert
    We extend results of Bonet, Buss and Pitassi on Bondy's Theorem and of Nozaki, Arai and Arai on Bollobas' Theorem by proving that Frankl's Theorem on the trace of sets has quasipolynomial size Frege proofs. For constant ...
  • Mining structured Petri nets for the visualization of process behavior 

    San Pedro Martín, Javier de; Cortadella Fortuny, Jordi (Association for Computing Machinery (ACM), 2016)
    Text en actes de congrés
    Accés obert
    Visualization is essential for understanding the models obtained by process mining. Clear and efficient visual representations make the embedded information more accessible and analyzable. This work presents a novel approach ...
  • A genetic algorithm-based system for Wireless Mesh Networks: analysis of system data considering different routing protocols and architectures 

    Oda, Tetsuya; Elmazi, Donald; Barolli, Admir; Sakamoto, Shinji; Barolli, Leonard; Xhafa Xhafa, Fatos (Springer, 2016-07-01)
    Article

    Wireless mesh networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in ...
  • Adaptive transfer functions: improved multiresolution visualization of medical models 

    Díaz García, Jesús; Brunet Crosa, Pere; Navazo Álvaro, Isabel; Pérez, Frederic; Vázquez Alcocer, Pere Pau (Springer, 2016-05-14)
    Article
    Accés restringit per política de l'editorial
    Medical datasets are continuously increasing in size. Although larger models may be available for certain research purposes, in the common clinical practice the models are usually of up to 512x512x2000 voxels. These ...
  • Impostor-based crowd rendering 

    Beacco Porres, Alejandro; Pelechano Gómez, Núria; Andújar Gran, Carlos Antonio (CRC Press, 2016-09-27)
    Capítol de llibre
    Accés restringit per política de l'editorial
    Real-time rendering of detailed animated characters in crowd simulations is still a challenging problem in computer graphics. State-of-the-art approaches can render up to several thousand agents by consuming most of the ...
