  • Multisided patches 

    Pla García, Núria; Vigo Anglada, Marc; Cotrina Navau, Josep (2004-06)
    Report de recerca
    Accés obert
    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)
    Report de recerca
    Accés obert
    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)
    Report de recerca
    Accés obert
    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 ...
  • MALLBA: a library of skeletons for combinatorial optimisation 

    Alba, E; Almeida, F; Blesa Aguilera, Maria Josep; Cabeza, J; Cotta, C; Díaz, M; Dorta, I; Gabarró Vallès, Joaquim; León, C; Luna Garcia, Jesus; Moreno Boronat, Lidia Ana; Pablos, C; Petit Silvestre, Jordi; Rojas Espinosa, Alfonso; Xhafa Xhafa, Fatos (2002-02)
    Report de recerca
    Accés obert
    The MALLBA project tackles the resolution of combinatorial optimization problems using algorithmic skeletons implemented in C++. MALLBA offers three families of generic resolution methods: exact, heuristic and hybrid. ...
  • Free form surfaces 

    Cotrina Navau, Josep; Pla García, Núria (2000-05)
    Report de recerca
    Accés obert
    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)
    Report de recerca
    Accés obert
    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 ...
  • Current Trends of Topology Discovery in OpenFlow-based Software Defined Networks 

    Ochoa Aday, Leonardo; Cervelló Pastor, Cristina; Fernández Fernández, Adriana (2015-09)
    Report de recerca
    Accés obert
    The explosion of Internet services such as video on demand, big data, server virtualization and cloud services is among the trends driving the networking industry to change traditional network architectures to more flexible ...
  • Economía de la accesibilidad 20+20 : marco teórico 

    Guasch Murillo, Daniel; Berbegal Mirabent, Jasmina; Villalta, Marta (2012)
    Report de recerca
    Accés obert
  • Hierarchical categorisation of web tags for Delicious 

    Parra Arnau, Javier; Perego, Andrea; Ferrari, Elena; Forné Muñoz, Jorge; Rebollo Monedero, David (2011-11-11)
    Report de recerca
    Accés obert
    In the scenario of social bookmarking, a user browsing the Web bookmarks web pages and assigns free-text labels (i.e., tags) to them according to their personal preferences. The benefits of social tagging are clear – tags ...
  • Influence maximization in social Networks when negative opinions may emerge and propagate 

    Yuan, Yifei; Wei, Wei; Chen, Wei; Collins, Alex; Cummings, Rachel; Ke, Te; Liu, Zhenming; Rincón Rivera, David; Sun, Xiaorui; Wang, Yajun (2010-10-01)
    Report de recerca
    Accés obert
    Influence maximization, defined by Kempe, Kleinberg, and Tardos (2003), is the problem of finding a small set of seed nodes in a social network that maximizes the spread of influence under certain influence cascade ...
