      Road network analysis can require distance from points that are not on the network themselves. We study the algorithmic problem of connecting a point inside a face (region) of the road network to its boundary while ...
    • Integrity monitoring for carrier phase ambiguities 

      Jofre, Martí; Ramos Bosch, Pedro; Feng, S.; Ochieng, W.; Samson, J; Tossaint, M; Hernández Pajares, Manuel; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Aragón Ángel, María Ángeles (2012-01)

      The determination of the correct integer number of carrier cycles (integer ambiguity) is the key to high accuracy positioning with carrier phase measurements from Global Navigation Satellite Systems (GNSS). There are a ...
    • Unstructured and semi-structured hexahedral mesh generation methods

      Discretization techniques such as the finite element method, the finite volume method or the discontinuous Galerkin method are the most used simulation techniques in ap- plied sciences and technology. These methods rely ...
    • Using a computational domain and a three-stage node location procedure for multi-sweeping algorithms 

      Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2011)

      Accés obert
      The multi-sweeping method is one of the most used algorithms to generate hexahedral meshes for extrusion volumes. In this method the geometry is decomposed in sub-volumes by means of projecting nodes along the sweep direction ...
