    • Compact union of disjoint boxes: An efficient decomposition model for binary volumes 

      Cruz Matías, Irving; Ayala Vallespí, M. Dolors (2017)
      Article
      Accés obert
      This paper presents in detail the CompactUnion of Disjoint Boxes (CUDB), a decomposition modelfor binary volumes that has been recently but brieflyintroduced. This model is an improved version of aprevious model called ...

    • CUDB: An improved decomposition model for orthogonal pseudo-polyhedra 

      Cruz Matías, Irving; Ayala Vallespí, M. Dolors (2011)
      Report de recerca
      Accés obert
      We present a new decomposition model for Orthogonal Pseudo-Polyhedra (OPP): the Compact Union of Disjoint Boxes. This model is an improved version of the Ordered Union of Disjoint Boxes model. Our model has many desirable ...

    • Orientation, sphericity and roundness evaluation of particles using alternative 3D representations 

      Cruz Matías, Irving; Ayala Vallespí, M. Dolors (2014)
      Report de recerca
      Accés obert
      Sphericity and roundness indices have been used mainly in geology to analyze the shape of particles. In this paper, geometric methods are proposed as an alternative to evaluate the orientation, sphericity and roundness ...

    • Skeletonless porosimeter simulation 

      Rodríguez, Jorge; Cruz Matías, Irving; Vergés Garcia, Eduard; Ayala Vallespí, M. Dolors (2010)
      Report de recerca
      Accés obert
      We introduce a new approach to simulate a virtual mercury intrusion porosimetry (MIP) using neither skeleton computing nor seed-growing methods. Most of the existing methods to determine local pore sizes in a porous medium ...

    • Sphericity and roundness computation for particles using the extreme vertices model 

      Cruz Matías, Irving; Ayala Vallespí, M. Dolors; Hiller, Daniel; Gutsch, Sebastian; Zacharias, Margit; Estradé, Sònia; Peiró Martínez, Francesca (Elsevier, 2019-01-01)
      Article
      Accés obert
      Shape is a property studied for many kinds of particles. Among shape parameters, sphericity and roundness indices had been largely studied to understand several processes. Some of these indices are based on length measurements ...
