Stabbing simplices of point sets with k-flats
(2013)
Let S be a set of n points in Rd in general position. A set H of k-flats is called an mk-stabber of S if the relative interior of any m-simplex with vertices in S is intersected by at least one element of H. In this paper ...

Designing robust rapid transit networks with alternative routes
(Hindawi, 2011-01)
The aim of this paper is to propose a model for the design of a robust rapid transit network. In this paper, a network is said to be robust when the effect of disruption on total trip coverage is minimized. The proposed model ...

Computing the stretch of an embedded graph
(2013)
Let G be a graph embedded in an orientable surface Σ, possibly with edge weights, and denote by len(γ) the length (the number of edges or the sum of the edge weights) of a cycle γ in G. The stretch of a graph embedded on ...

Filling and wetting transitions on sinusoidal substrates: a mean-field study of the Landau-Ginzburg model
(IOP Publishing, 2014)
We study the interfacial phenomenology of a fluid in contact with a one-dimensional array of infinitely long grooves of sinusoidal section, characterized by the periodicity length L and amplitude A. The system is modelled ...

Volterra operators and semigroups in weighted Banach spaces of analytic functions
(Springer Open Choice, 2014)
We characterize the boundedness, compactness and weak compactness of Volterra operators Vg( f )(z) := z 0 f (ζ )g (ζ ) dζ acting between different weighted spaces of type H∞ v in terms of the symbol function g, ...

Node aggregation for enhancing PageRank
(IEEE-Institute of Electrical and Electronics Engineers, 2017)
In this paper, we study the problem of node aggregation under different perspectives for increasing PageRank of some nodes of interest. PageRank is one of the parameters used by the search engine Google to determine the ...

Metaheuristic approaches for the minimum dilation triangulation problem
(2013)
We focus on the development of approximated algorithms to find high quality triangulations of minimum dilation because the complexity status of the Minimum Dilation Triangulation problem for a general point set is unknown. ...
