  • Bounds on the coefficients of tension and flow polynomials 

    Breuer, Felix; Dall, Aaron Matthew (2011-05)
    Article
    Restricted access - publisher's policy
    The goal of this article is to obtain bounds on the coefficients of modular and integral flow and tension polynomials of graphs. To this end we use the fact that these polynomials can be realized as Ehrhart polynomials of ...
  • Bounds on the first non-null eigenvalue for self-adjoint boundary value problems on networks

    Article
    Open Access
    We aim here at obtaining bounds on the first non-null eigenvalue for self-adjoint boundary value problems on a weighted network by means of equilibrium measures, that includes the study of Dirichlet, Neumann and Mixed ...
  • Bounds on the possible evolution of the gravitational constant from cosmological type-Ia supernovae

    Article
    Open Access
    Recent high-redshift type-Ia supernovae results can be used to set new bounds on a possible variation of the gravitational constant G. If the local value of G at the space-time location of distant supernovae is different, ...
  • Bounds on the size of super edge-magic graphs depending on the girth 

    Ichishima, Rikio; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2009-12-13)
    External research report
    Open Access
    Let G = (V,E) be a graph of order p and size q. It is known that if G is super edge-magic graph then q 2p−3. Furthermore, if G is super edge-magic and q = 2p−3, then the girth of G is 3. It is also known that if the ...
  • BoVDW: Bag-of-Visual-and-Depth-Words for gesture recognition 

    Hernandez Vela, Antonio; Bautista, Miguel Angel; Perez-Sala, Xavier; Ponce, Víctor; Baró, Xavier; Pujol, Oriol; Angulo Bahón, Cecilio; Escalera, Sergio (2012)
    Conference report
    Restricted access - publisher's policy
    We present a Bag-of-Visual-and-Depth-Words (BoVDW) model for gesture recognition, an extension of the Bag-of-Visual-Words (BoVW) model, that benefits from the multimodal fusion of visual and depth features. State-of-the-art ...

    The unique geometrical properties of fractals have been proven to be useful to design advanced antennas. Enhanced performance in terms of size, gain or multiband behaviour is observed in fractal-shaped antennas. Here, a ...
  • Box approximations of planar linkage configuration spaces 

    Porta Pleite, Josep Maria; Ros Giralt, Lluís; Creemers, Tom Lambert; Thomas, Federico (ASME International, 2007)
    Article
    Open Access
    This paper presents a numerical method able to compute all possible configurations of planar linkages. The procedure is applicable to rigid linkages (i.e., those that can only adopt a finite number of configurations) and ...
  • Box III-1: Comparing emissions from 9 European cities and their bus fleets 

    Roset Calzada, Jaime (Centre for Earth System Engineering Research, 2014-03)
    Part of book or chapter of book
    Open Access
    The urgent need to reconfigure urban areas to consume fewer resources, generate less pollution, be more resilient to the impacts of extreme events and become more sustainable in general, is widely recognised. To address ...

    Pastor Moreno, Rafael; Corominas Subias, Albert (Sociedad Española de Estadística e Investigación Operativa, 2004-06)
    Article
    Open Access
    Currently, most combinatorial optimisation problems have to be solved, if the optimum solution is sought, using general techniques to explore the space of feasible solutions and, more specifically, through exploratory ...
  • Branch switching from singular points in higher-dimensional continuation 

    Bohigas Nadal, Oriol (2011)
    External research report
