(INFORMS Inst.for Operations Res.and the Management Sciences, 2017)Public transit systems in major urban areas usually operate under deficits and therefore require significant subsidies. An important cause of this deficit, particularly in the developing world, is the high fare evasion ...
-
(Universidad de Chile, 2013)GPS data of vehicles travelling on road networks can be used to estimate travel times. This requires the identification of the corresponding paths in the network. We developed algorithms identifying a path minimizing a ...
-
(Springer, 2017)There are many representations of planar graphs but few are as elegant as Turán’s (1984): it is simple and practical, uses only four bits per edge, can handle multi-edges and can store any specified embedding. Its main ...

(Elsevier, 2020)There are many representations of planar graphs, but few are as elegant as Turan's (1984): it is simple and practical, uses only 4 bits per edge, can handle self-loops and multiedges, and can store any specified embedding. ...

(2010-09)Compressed graph representations, in particular for Web graphs, have become an attractive research topic because of their applications in the manipulation of huge graphs in main memory. The state of the art is well represented ...
-
(SPRINGER, 2008-08)We consider the elliptic problem Delta u + u(p) = 0, u > 0 in an exterior domain, Omega = R-N\D under zero Dirichlet and vanishing conditions, where D is smooth and bounded in R-N, N >= 3, and p is supercritical, namely p ...

(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)We introduce a compressed suffix array representation that, on a textTof lengthnover analphabet of sizeσ, can be built inO(n)deterministic time, withinO(nlogσ)bits of workingspace, and counts the number of occurrences of ...

(IEEE, 2015)Delayed signal cancellation is one of the methods used to separate the negative- and positive-sequence components in unbalanced systems. In this letter, a DSC methodology with fast convergence time is proposed and it ...
-
(Elsevier, 2000)A method for fast nucleotide sequencing is described. It is based in the selection of well-known small oligomers able to be hybridized with the unknown target. The selected oligomers are afterwards ordered following a ...
-
(Wiley-Blackwell, 2015)Extensible Markup Language (XML) documents consist of text data plus structured data (markup). XPath allows to query both text and structure. Evaluating such hybrid queries is challenging. We present a system for in-memory ...

(SPRINGER-VERLAG BERLIN, 2006)This paper proposes an improvement over the traditional SIFT-based object recognition methodology proposed by Lowe [3]. This improvement corresponds to a fast probabilistic model for hypothesis rejection (affine solution ...
-
(Society for Industrial and Applied Mathematics, 2013)In this paper we study the large-time behavior of solutions of one-dimensional fractional Fisher-KPP reaction-diffusion equations, when the initial condition is asymptotically frontlike and it decays at infinity more ...
-
(Osservatorio Astronomico di Padova (INAF), Italy, 2017)We present a long-term, multi-wavelength project to understand the epoch of fastest growth of the most massive black holes by using a sample of 40 luminous quasars at z similar or equal to 4.8. These quasars have rather ...
-
(Nature Publishing, 2015)In the 1980s, excess infrared emission was discovered around main-sequence stars; subsequent direct-imaging observations revealed orbiting disks of cold dust to be the source(1). These 'debris disks' were thought to be ...
-
(Frontiers Media S.A., 2019)Food intake in fish and mammals is orchestrated by hypothalamic crosstalk between orexigenic (food intake stimulation) and anorexigenic (food intake inhibition) signals. Some of these signals are released by peripheral ...
-
(CSIC, 2015)Gas-Liquid Chromatography (GLC) methods such as AOAC Fat in foods 966.06 (2005), AOCS Official Methods Ce 1h-05 (2005), Ce 1j-07 (2007), allow for analyzing the fatty acids (FAs) in dietary fats using highly polar liquid ...
-
(Elsevier, 2017)Paleofluid-transporting systems can be recognized as meshes of fracture-filled veins in eroded zones ofextinct hydrothermal systems. Here we combined meso-microstructural analysis of 107 fractures andmechanical modeling ...
-
(ELSEVIER, 2005-02-15)We describe Neogene drainage network development before, during and after regional folding in the Precordillera of the Andes of Northern Chile (18degrees-19degreesS). The drainage network developed on an extensive regular ...
