    Monclús Lahoya, Eva; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (IADIS Press, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Although Virtual Reality (VR) environments have seen slower adoption rates than expected among the medical community, throughout the last years, several new techniques and devices (e.g. Oculus Rift) have been developed ...
  • Dynamic learning of cases from data streams 

    Orduña Cabrera, Fernando; Sànchez-Marrè, Miquel (Real Academia de Ingeniería (RAI), 2016)
    Text en actes de congrés
    Accés obert
    This paper presents a dynamic adaptive framework for building a case library being able to cope with a data stream in the field of Case-Based Reasoning. The framework provides a three-layer architecture formed by a set of ...
  • Clustering of exchange rates and their dynamics under different dependence measures 

    Renedo, Martí; Arratia Quesada, Argimiro Alejandro (, 2016)
    Text en actes de congrés
    Accés obert
    This paper proposes an improvement to the method for clustering exchange rates given by D. J. Fenn et al, in Quantitative Finance, 12 (10) 2012, pp.1493-1520. To deal with the potentially non linear nature of currency time ...
  • Computing alignments with constraint programming : the acyclic case 

    Borrego, Diana; Gómez López, María Teresa; Carmona Vargas, Josep; Martínez Gasca, Rafael (CEUR-WS.org, 2016)
    Text en actes de congrés
    Accés obert
    Conformance checking confronts process models with real process executions to detect and measure deviations between modelled and observed behaviour. The core technique for conformance checking is the computation of an ...
  • Incremental learning fault detection algorithm based on hyperplane-distance 

    Ardakani, Mohammadhamed; Escudero Bakx, Gerard; Graells Sobré, Moisès; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Traditional methods for Fault Detection and Diagnosis (FDD) usually, consider that processes operate under a single steady condition, but because of several reasons (e.g.: equipment aging), operation conditions of ...
  • Kriging based fault detection and diagnosis approach for nonlinear noisy dynamic processes 

    Shokry, Ahmed; Ardakani, Mohammadhamed; Escudero Bakx, Gerard; Graells Sobré, Moisès; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a hybrid approach to enhance the performance of the data-based Pattern Classification Techniques (PCTs) used for Fault Detection and Diagnosis (FDD) of nonlinear dynamic noisy processes. The method ...
  • Optimal features selection for designing a fault diagnosis system 

    Ardakani, Mohammadhamed; Askarian, Mahdieh; Shokry, Ahmed; Escudero Bakx, Gerard; Graells Sobré, Moisès; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés

    Fault diagnosis (FD) using data-driven methods is essential for monitoring complex process systems, but its performance is severely affected by the quality of the used information. Additionally, processing huge amounts of ...
  • Automated construction and analysis of political networks via open government and media sources 

    García-Olano, Diego; Arias Vicente, Marta; Larriba Pey, Josep (2016)
    Text en actes de congrés
    Accés obert
    We present a tool to generate real world political networks from user provided lists of politicians and news sites. Additional output includes visualizations, interactive tools and maps that allow a user to better understand ...
  • A software framework for the development of projection-based augmented reality systems 

    Sunet Pérez, Marc; Comino Trinidad, Marc; Karatzas, Dìmosthenis; Chica Calaf, Antonio; Vázquez Alcocer, Pere Pau (2010)
    Comunicació de congrés
    Accés obert
    Despite the large amount of methods and applications of augmented reality, there is little homogenization on the software platforms that support them. An exception may be the low level control software that is provided by ...
  • Characterization of order-like dependencies with formal concept analysis 

    Codocedo, Victor; Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2011)
    Text en actes de congrés
    Accés obert
    Functional Dependencies (FDs) play a key role in many fields of the relational database model, one of the most widely used database systems. FDs have also been applied in data analysis, data quality, knowl- edge discovery ...
