  • Parameter tunning for PBIL algorithm in geometric constraint solving systems 

    Joan Arinyo, Robert; Luzón, M.V.; YEGUAS BOLÍAVAR, ENRIQUE (2008-08-14)
    Conference report
    Open Access
    In previous works we have shown that applying genetic algorithms to solve the Root Identification Problem is feasible and effective. The behavior of evolutive algorithms is characterized by a set of parameters that have ...
  • Enhancing computerized cognitive rehabilitation with 3D solutions 

    Alloni, Anna; Panzarasa, Silvia; Quaglini, Silvana; Zuchella, Chiara; Tost Pardell, Daniela (2014)
    Conference report

    In recent years, cognitive rehabilitation is shifting from paper-based to computer-based practice. Computerization entails several advantages, among which the availability of a great amount of stimuli to be used within a ...
  • Serious games for screening pre-dementia conditions: from virtuality to reality? A pilot project 

    Zuchella, Chiara; Sinforiani, Elena; Tassorelli, Cristina; Cavallini, Elena; Tost Pardell, Daniela; Grau Carrion, Sergi; Pazzi, Stefania; Puricelli, Stefano; Bernini, Sara; Bottiroli, Sara; Vecchi, Tomaso; Sandrini, Giorgio; Nappi, Giuseppe (2014-11-02)

    Conventional cognitive assessment is based on a pencil-and-paper neuropsychological evaluation, which is time consuming, expensive and requires the involvement of several professionals. Information and communication ...
  • SmartAgeing: a 3D serious game for early detection of mild cognitive impairments 

    Tost Pardell, Daniela; von Barnekow, Ariel; Felix Manzanares, Eloy; Pazzi, Stefania; Puricelli, Stefano; Bottiroli, Sara (2014)
    Conference report
    Restricted access - publisher's policy
    We describe the Smart Ageing, a serious game in a 3D virtual environment aimed at the early detection of Mild Cognitive Impairments in persons ageing between 50 and 60, and at assessing cognitive impairments in persons ...
  • Decomposition of geometric constraint graphs based on computing fundamental circuits. Correctness and complexity 

    Joan Arinyo, Robert; Tarres Puertas, Marta Isabel; Vila Marta, Sebastià (2014-07-01)
    Article
    Restricted access - publisher's policy
    In geometric constraint solving, Decomposition Recombination solvers (DR-solvers) refer to a general solving approach where the problem is divided into a set of sub-problems, each sub-problem is recursively divided until ...
  • The three-dimensional cube and scale cube skeleton 

    Martínez Bayona, Jonàs; Pla García, Núria; Vigo Anglada, Marc (Springer, 2014)
    Article
    Restricted access - publisher's policy
    The recently introduced cube and scale cube skeleton of Martínez et al. (Graph Models 75:189–207, 2013) are a new type of skeletal representations for polygons or polyhedra enclosed by axis-aligned edges or faces. In this ...
  • Co-creation of a serious game to develop competences on the primary education program 

    Eguía Gómez, Jose Luis; Contreras Espinoza, Ruth Sofia; Solano Albajés, Lluís (2014)
    Conference report
    Restricted access - publisher's policy
    This paper presents the research work carried out by an interdisciplinary group of technologists and entertainment experts in collaboration with primary teachers to develop a serious game to work primary education-oriented ...
  • First-person locomotion in 3D virtual environments: a usability analysis 

    Moya Santos, Sergio; Grau Carrion, Sergi; Tost Pardell, Daniela (2014)
    Article
    Open Access
    3D Virtual Environments (VE) are becoming popular as a tool for cognitive, functional and psychological assessment. Navigation in these environments is recognized as one of the most difficult activities in 3D Virtual ...
  • A practical and robust method to compute the boundary of three-dimensional axis-aligned boxes 

    López Monterde, Daniel; Martínez Bayona, Jonàs; Vigo Anglada, Marc; Pla García, Núria (2014)
    Conference report
    Open Access
    The union of axis-aligned boxes results in a constrained structure that is advantageous for solving certain geometrical problems. A widely used scheme for solid modelling systems is the boundary representation (Brep). We ...
  • A new lossless orthogonal simplification method for 3D objects based on bounding structures 

    Cruz Matías, Irving Alberto; Ayala Vallespí, M. Dolors (2014-07)
    Article
    Restricted access - publisher's policy
    This paper presents a new approach to simplify 3D binary images and general orthogonal pseudo-polyhedra (OPP). The method is incremental and produces a level-of-detail sequence of OPP, where any object of this sequence ...
