  • Multisided patches 

    Pla García, Núria; Vigo Anglada, Marc; Cotrina Navau, Josep (2004-06)
    External research report
    Open Access
    We present a method to construct a patch of parametric surface of degree k + 1 that lls a n-sided hole, with n bigger than 2, and whose boundary coincides with a B-Spline, thus, the resulting patch can be easily connected ...
  • N-sided patches with B-spline boundaries 

    Cotrina Navau, Josep; Pla García, Núria; Vigo Anglada, Marc (2001-12)
    External research report
    Open Access
    We present a method to construct a patch of parametric surface of degree k+1 that fills a n-sided hole, with bigger than 2, and whose boundary coincides with a B-Spline, thus, the resulting patch can be easily connected ...
  • Towards free form surfaces 

    Cotrina Navau, Josep; Pla García, Núria; Vigo Anglada, Marc (2001-03)
    External research report
    Open Access
    A theoretical approach to construct free form surfaces is presented. We develop the conceps that arise when a free form surface is generated by tracing a mesh, using differentiable manifold theory, and generalizing the ...
  • Free form surfaces 

    Cotrina Navau, Josep; Pla García, Núria (2000-05)
    External research report
    Open Access
    A method to construct continuous order k surfaces of arbitrary topological type by tracing a mesh that represents a 2-manifold is presented. The presented approach constructs the surface from a collection of pieces which ...
  • Modelling surfaces from planar irregular meshes 

    Cotrina Navau, Josep; Pla García, Núria (1998-06)
    External research report
    Open Access
    We present a method for constructing surfaces from irregular control meshes that can be embedded in the plane. This method results from a generalization of B-Splines using the known technology of manifolds. The resulting ...

    Aquest treball té com a objectiu analitzar la situació actual de la Internet, per proposar noves alternatives i dibuixar un possible camí cap a la Internet del Futur. Aquesta anàlisi vol ser un punt de partida, un document ...
  • Available Admission Capacity Estimations in IEEE 802.11 Access Points 

    García Villegas, Eduard (2008-04-01)
    External research report
    Open Access
    This technical report is intended to provide extended information about the Available Admission Capacity estimation mechanism for IEEE 802.11 cells previously presented. The original formulation has been revised in this ...
