    • Rahmann Zúñiga, Claudia; Chamas, Sebastián Ignacio; Álvarez, Ricardo; Chávez, Héctor; Ortiz Villalba, Diego; Shklyarskiy, Yaroslav (IEEE, 2020)
      Moving towards low-carbon electricity systems through the massive deployment of renewable energy sources (RES) presents a unique opportunity to combat climate change, but it also poses enormous technical challenges, ...
    • Pérez Flores, Claudio; Cament Riveros, Leonardo; Castillo, Luis E. (Elsevier, 2011-04)
      Face recognition has a wide range of possible applications in surveillance, human computer interfaces and marketing and advertising goods for selected customers according to age and gender. Because of the high classification ...
    • Wolff Rojas, Patricio; Ríos Pérez, Sebastián; Clavijo, David; Grana, Manuel; Carrasco, Miguel (BMC, 2020)
      Background Medical knowledge is accumulated in scientific research papers along time. In order to exploit this knowledge by automated systems, there is a growing interest in developing text mining methodologies to extract, ...
    • Muñoz Carpintero, Diego; Sáez Hueichapán, Doris; Cortés Carrillo, Cristián; Núñez, Alfredo (INFORMS, 2015)
      This paper presents a methodology based on generic evolutionary algorithms to solve a dynamic pickup and delivery problem formulated under a hybrid predictive control approach. The solution scheme is designed to support ...
    • Fuente Stranger, Alberto de La (American Society of Civil Engineers, 2015)
      Dissolved oxygen (DO) consumption in the sediments of natural aquatic ecosystems occurs by mass flux across the water-sediment interface. This mass flux is determined as either the rate of oxygen consumption in the sediment ...
    • Crespo, Fernando; Weber, Richard (ELSEVIER SCIENCE BV, 2005-03-01)
      Dynamic data mining is increasingly attracting attention from the respective research community. On the other hand, users of installed data mining systems are also interested in the related techniques and will be even more ...
    • Vallejos Massa, Javier; Basaure, K.; Palma, S.; Castro, R. L. (Southern African institute mining metallurgy, 2017)
      Mud rushes are sudden inflows of fine wet ore within underground mines; they can harm people and equipment as well as cause production delays. Block and panel caving mines are prone to mud rushes in their production levels, ...
    • Román Figueroa, Celián; Herrera, Sebastián; Cortez, Donna; Uribe, Juan Manuel; Paneque Corrales, Manuel (Taylor and Francis Ltd., 2019)
      Atriplex includes species with multiple purposes such as biomass for energy production, for bioremediation of soils contaminated with metals, or soil conservation. In Chile, 29 Atriplex species have been recorded, of which ...
    • Jara Díaz, Sergio; Vergara, Cristián; Gálvez Pérez, Tristán (TAYLOR & FRANCIS LTD, 2006-07)
      A new methodology for the estimation of social values of urban air pollution for project appraisal is proposed. This is performed by using individual perceptions (marginal disutilities) of those who are directly affected ...
    • Boisvert, J. B.; Leuangthong, Oy; Ortiz Cabrera, Julián; Deutsch, C. V. (PERGAMON-ELSEVIER SCIENCE LTD, 2008-05)
      Fracture models of vein formation can produce realistic training images (TIs) for use in multiple-point geostatistics. Vein formation is modeled by applying flow simulation to a fracture model to mimic the flow of an ...
    • Soto Bustamante, Eduardo; Vásquez, Sergio O.; Romero-Hasler, Patricio (Elsevier B.V., 2019)
      We have studied the effect of a static external electric field on electronic properties of methyl methacrylate (MMA) and its consequences in an electro-initiated polymerization by density functional theory (DFT). The ...
    • Daniilidis, Aris; Deville, Robert; Durand-Cartagena, Estibalitz (Springer New York LLC, 2019)
      © 2018, Springer Science+Business Media, LLC, part of Springer Nature.The metric notion of a self-contracted curve (respectively, self-expanded curve, if we reverse the orientation) is hereby extended in a natural way. Two ...
    • Chávez, Edgar; Navarro, Gonzalo (ELSEVIER, 2006-03-07)
      We present a radically new indexing approach for approximate string matching. The scheme uses the metric properties of the edit distance and can be applied to any other metric between strings. We build a metric space where ...
    • Navarro, Gonzalo; Chávez, Edgar (Elsevier, 2006)
      We present a radically new indexing approach for approximate string matching. The scheme uses the metric properties of the edit distance and can be applied to any other metric between strings. We build a metric space ...
    • Barrios, Pablo; Adams, Martin; Leung, Keith; Inostroza, Felipe; Naqvi, Ghayur; Orchard Concha, Marcos (IEEE, 2017)
      Inrobotic mapping and simultaneous localization and mapping, the ability to assess the quality of estimated maps is crucial. While concepts exist for quantifying the error in the estimated trajectory of a robot, or a ...
    • Bui, Thi Thu Cuc; Frey, Pascal; Maury, Bertrand (ELSEVIER, 2008-06)
      In this Note, we present a method to solve numerically the Stokes equation for the incompressible flow between two immiscible fluids presenting very different viscosities. The resolution of the finite element systems of ...
    • Ehrich, Jannik; Esposito, Massimiliano; Barra de la Guarda, Felipe; Parrondo, Juan M. R. (Elsevier, 2020)
      Micro-reversibility plays a central role in thermodynamics and statistical mechanics. It is used to prove that systems in contact with a thermal bath relax to canonical ensembles. However, a problem arises when trying to ...
    • Atroshchenko, Elena; Hale, Jack S.; Videla, Javier A.; Potapenko, Stanislav; Bordas, Stephane P. A. (Elsevier, 2017)
      In this paper we tackle the simulation of microstructured materials modelled as heterogeneous Cosserat media with both perfect and imperfect interfaces. We formulate a boundary value problem for an inclusion of one plane ...
