    • A logistic queue model for network traffic modeling and simulation 

      Coltraro, Franco (Universitat Politècnica de Catalunya, 2017-07)
      Master thesis
      Open Access
      In this work we present a continuous queuing model called the logistic queue model. We show that in terms of queue size and outflow prediction, our model is as precise as a discrete event simulator with the additional ...
    • A representation of cloth states based on a derivative of the Gauss linking integral 

      Coltraro, Franco; Fontana, Josep; Amorós Torrent, Jaume; Alberich Carramiñana, Maria; Borràs Sol, Júlia; Torras, Carme (Elsevier, 2023-11-15)
      Article
      Open Access
      Robotic manipulation of cloth is a complex task because of the infinite-dimensional shape-state space of textiles, which makes their state estimation very difficult. In this paper we introduce the dGLI Cloth Coordinates, ...
    • An inextensible model for the robotic manipulation of textiles 

      Coltraro, Franco; Amorós Torrent, Jaume; Alberich Carramiñana, Maria; Torras, Carme (2022-01-01)
      Article
      Open Access
      We introduce a new isometric strain model for the study of the dynamics of cloth garments in a moderate stress environment, such as robotic manipulation in the neighborhood of humans. This model treats textiles as surfaces ...
    • CURSA-SQ: a methodology for service-centric traffic flow analysis 

      Ruiz Ramírez, Marc; Coltraro, Franco; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2018-09-01)
      Article
      Open Access
      The rapid availability of new services means that network operators cannot exhaustively test their impact on the network or anticipate any capacity exhaustion. This situation will be worse with the imminent introduction ...
    • Developable surfaces with prescribed boundary 

      Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro, Franco (Springer-Birkhäuser, 2021)
      Part of book or chapter of book
      Open Access
      It is proved that a generic simple, closed, piecewise regular curve in space can be the boundary of only infinitely many developable surfaces with nonvanishing mean curvature. The relevance of this result in the context ...
    • Experimental validation of an inextensible cloth model 

      Coltraro, Franco (2020)
      Research report
      Open Access
      In this technical report we present a framework for the empirical validation of a physical cloth model. First, we introduce the model to be validated and its parameters, next we explain how to obtain real world data of the ...
    • Morse cell decomposition and parametrization of surfaces from point clouds 

      Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro, Franco; Torras, Carme; Verdaguer López, Miquel (Publicacions de la Universitat Jaume I, 2022)
      Conference report
      Open Access
      An algorithm for the reconstruction of a surface from a point sample is presented. It proceeds directly from the point-cloud to obtain a cellular decomposition of the surface derived from a Morse function. No intermediate ...
    • Reconstruction of sampled surfaces with boundary via Morse theory 

      Coltraro, Franco; Amorós Torrent, Jaume; Alberich Carramiñana, Maria; Torras, Carme (European Association for Computer Graphics (Eurographics), 2023)
      Conference report
      Open Access
      We study the perception problem for garments (e.g. a pair of pants) using tools from computational topology: the identification of their geometry and position from point-cloud samples, as obtained e.g. with 3D scanners. ...
    • Robotic manipulation of cloth: mechanical modeling and perception 

      Coltraro, Franco (Universitat Politècnica de Catalunya, 2023-03-30)
      Doctoral thesis
      Open Access
      (Eng) In this work we study various mathematical problems arising from the robotic manipulation of cloth. First, we develop a locking-free continuous model for the physical simulation of inextensible textiles. We present ...
