  • State-of-the-art: Frame-to-frame coherence in volume rendering 

    Grau Carrion, Sergi (2008-02)
    External research report
    Open Access
    In this report we review the state-of-the-art in frame-to-frame coherence in time-varying volume rendering.
  • Parallel partition revisited 

    Frias Moya, Leonor; Petit Silvestre, Jordi (2008-02)
    External research report
    Open Access
    In this paper we consider parallel algorithms to partition an array with respect to a pivot. We focus on implementations for current widely available multi-core architectures. After reviewing existing algorithms, we propose ...
  • Splatting multiresolution volume data using the feature graph 

    Campos, J.; Puig, A.; Tost Pardell, Daniela (2008-01)
    External research report
    Open Access
    We propose to represent classified datasets as a feature graph storing different graphical models and attributes for each feature. This graph allows us to render each feature according to its own characteristics. In addition, ...
  • PHAST: Spoken document retrieval based on sequence alignment 

    Comas Umbert, Pere Ramon; Turmo Borras, Jorge (2008-01)
    External research report
    Open Access
    This paper presents a new approach to spoken document information retrieval for spontaneous speech corpora. Classical approach to this problem is the use of an automatic speech recognizer (ASR) combined with standard ...
  • An approach for an architecture to embodied procedural reasoning 

    Orduña Cabrera, Fernando; Sánchez Marrè, Miquel (2008-01)
    External research report
    Open Access
    Some research in intelligent manufacturing systems summarizes the importance of developing new methods and techniques that should be more knowledge intensive, applied at the level of embedded devices. To bring a solution ...
  • Feature selection for support vector machines by alignment with ideal kernel 

    Catala Roig, Neus; Martín Muñoz, Mario (2007-12)
    External research report
    Open Access
    Feature selection has several potentially beneficial uses in machine learning. Some of them are to improve the performance of the learning method by removing noisy features, to reduce the feature set in data collection, ...
  • Virtual porosimeter 

    Vergés, Eduard; Ayala Vallespí, M. Dolors; Grau Carrion, Sergi; Tost Pardell, Daniela (2007-12)
    External research report
    Open Access
    Recently, the term BioCAD has appeared to refer to the modeling of biological processes. This work focuses on the analysis of structural properties such as porosity of bioimplants for bone reconstruction. Specifically, we ...
  • iStarML: The i* mark-up language 

    Cares, Carlos; Franch Gutiérrez, Javier; Perini, Anna; Susi, Angelo (2007-09)
    External research report
    Open Access
    Goal-oriented and agent-oriented modelling provides an effective approach to the understanding of nowadays distributed information systems that need to operate in open, heterogeneous and evolving environments. Existing ...
  • Concept sense disambiguation in concept maps using WordNet 

    Simón Cuevas, Alfredo; Ceccaroni, Luigi; Rosete Suárez, Alejandro (2007-12)
    External research report
    Open Access
    In this report an unsupervised and knowledge-based algorithm for concept sense disambiguation in concept maps is proposed. Concept maps are graphical tools for organizing and representing knowledge, based on concepts and ...
  • Predicción del rendimiento de CHC y PBIL aplicados al problema de la solución deseada 

    Joan Arinyo, Robert; Luzón, M.V.; Yeguas, E. (2007-12)
    External research report
    Open Access
    El incremento de la complejidad de las instancias del problema de la selección de la solución deseada en resolución de restricciones geométricas supone un aumento considerable del tiempo requerido por las diferentes ...
