    • openAccess   Adaptive Mesh Refinement Strategy for the SemiAnalytical Solution of Frictionless Elastic Contact Problems 

      Roda-Casanova, Victor; Sanchez-Marin, Francisco IntechOpen (2018)
      Semi-analytical methods are commonly used to solve contact problems. These methods require the discretization of the domain into a mesh of pressure elements. In general, it can be said that their accuracy increases as ...
    • openAccess   An Algorithm for Grouping Lines Which Converge to Vanishing Points in Perspective Sketches of Polyhedra

    • openAccess   Are we training our novices towards quality 2D profiles for 3D models? 

      González-Lluch, Carmen; Plumed, Raquel Springer (2019)
      In the history-based, feature-based, parametric CAD approach, 2D profile sketches are the basis for 3D models. Fully-constraining profiles is mandatory to create robust profiles. At present, neither CAD applications nor ...

      Sustainable transition is ongoing in many refrigeration and heat pump applications following what is established in national and international regulations. However, many of them have not controlled ultra-low temperature ...
    • openAccess   Estudios de caracterización cinemática de la mano sana en actividades de la vida diaria 

      Vergara, Margarita; Sancho-Bru, Joaquin L.; Gracia-Ibáñez, Verónica (2016-04-06)
      El aumento de la esperanza de vida ha incrementado la prevalencia de enfermedades que afectan en gran medida a la capacidad manipulativa de la mano y por tanto al desarrollo de actividades de la vida diaria (AVD) necesarias ...
    • openAccess   Features and design intent in engineering sketches 

      Plumed, Raquel; Varley, Peter Ashley Clifford; Company, Pedro ©Springer-Verlag Berlin Heidelberg (2013)
      We investigate the problem of determining design intent from engineering sketches: what did the designer have in mind when sketching a component? Specifically, we consider the unidirectional reverse mapping from form ...
    • openAccess   Human perception in segmentation of sketches 

      Company, Pedro; Varley, Peter Ashley Clifford; Piquer, Ana; Vergara, Margarita; Sánchez-Rubio Ruiz, Jaime Springer Berlin Heidelberg (2010)
      In this paper, we study the segmentation of sketched engineering drawings into a set of straight and curved segments. Our immediate objective is to produce a benchmarking method for segmentation algorithms. The criterion ...
