    • Grandoni, Fabrizio; Wiese, Andreas; Mömke, Tobias; Zhou, Hang (Association for Computing Machinery, 2018)
      In the unsplittable flow on a path problem (UFP) we are given a path with edge capacities and a collection of tasks. Each task is characterized by a subpath, a profit, and a demand. Our goal is to compute a maximum ...

(IOP Publishing, 2018-08-20)
      Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (less than or similar to kpc) and global galaxy environment. We present first results from two large ...

      Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (≲kpc) and global galaxy environment. We present first results from two large observing programs on the ...
    • Loncomilla, Patricio; Ruíz del Solar San Martín, Javier; Saavedra A., Marcelo (Springer, 2018)
      The main goal of this paper is to propose a Bayesian based methodology for implementing robot informed search for objects. The methodology uses convolutions between observation likelihoods of secondary objects and spatial ...
    • Araya Hernández, Lerko; Osses Alvarado, Axel; Silva Sánchez, Jorge; Tobar Henríquez, Felipe Arturo (IEEE, 2017)
      The interferometry problem addresses the estimation of an unknown quantity exploiting the interference among measurements from different sources. These measurements are obtained from the Fourier domain but are sparse and ...

    • Valenzuela Fernández, Leslier; Merigó Lindahl, José; Lichtenthal, J. David; Nicolas, Carolina (Routledge, 2019)
      Purpose: As part of the recognition of the 25th anniversary of the Journal of Business-to-Business Marketing (JBBM), this paper presents an overview of the JBBM through a bibliometric analysis (BA) of its content from 1992 ...
    • Lagos, Felipe; Ordóñez Pizarro, Fernando; Labbé, Martine (Elsevier, 2017)
      Mixed integer optimization formulations are an attractive alternative to solve Stackelberg Game problems thanks to the efficiency of state of the art mixed integer algorithms. In particular, decomposition algorithms, such ...

      A multi-period stochastic model and an algorithmic approach to location of prison facilities under uncertainty are presented and applied to the Chilean prison system. The problem consists of finding locations and sizes of ...
    • Montecinos, Gino I.; Balsara, Dinshaw S. (Elsevier, 2017)
      In this paper, a family of high-order space-time polynomials in the context of continuous and discontinuous Galerkin methods is proposed. The resulting Galerkin schemes are used as a building block in ADER methods for ...
    • Casassus Montero, Simón; Nyman, L. A.; Dickinson, C.; Pearson, T. J. (WILEY-BLACKWELL, 2007-12-21)
      We report a centimetre-wave (cm-wave, 5-31 GHz) excess over free-free emission in planetary nebulae (PNe). Accurate 31- and 250-GHz measurements show that the 31-GHz flux densities in our sample are systematically higher ...
    • Gouet Bañares, Raúl; López, F. Javier; Sanz, Gerardo (2007)
      Let (Xn) be a sequence of nonnegative, integrable, independent and identically distributed random variables, with common distribution function F. We consider the problem of finding all distribution functions F such that ...
