(Institute of Electrical and Electronics Engineers Inc., 2019)In this paper, we investigate a joint resource allocation problem based on cognitive radio (CR) techniques for user equipment with multi-homing capabilities. We consider a heterogeneous wireless medium where users in ...
-
(International Association for Mathematical Geosciences, 2015)This work deals with the joint simulation of copper grade (as a continuous regionalized variable) and rock type (as a categorical variable) in Lince–Estefanía deposit, located in northern Chile. The region under study ...
-
(Universidad de Chile, 2016)La simulación geoestadística se usa ampliamente en ingeniería de minas para cuantificar la incertidumbre geológica, al producir múltiples realizaciones alternativas de la distribución de los recursos in situ y/o reservas ...
-
(Elsevier, 2017)In mineral resources evaluation, the joint simulation of a quantitative variable, such as a metal grade, and a categorical variable, such as a rock type, is challenging when one wants to reproduce spatial trends of the ...

-
(Elsevier, 2018-06)The Atacama Desert represents one of the driest regions on earth, and despite the absence of sustainable clean water reserves the demand has increased drastically since 1970 as a result of growing population and expanding ...
-
(Elsevier, 2014)A phenomenological theory is developed, that accounts for the collective dynamics of a Bose–Einstein condensate of magnons. In terms of such description we discuss the nature of spontaneous macroscopic interference ...
-
(Universidad de Chile, 2017)Los jóvenes que no estudian ni trabajan en Chile, están compuesto por 509 mil jóvenes entre los 15 y 24 años, representando un 17,2% de dicha población según datos de la CASEN 2013. En su mayoría son mujeres (62,4% versus ...
-
(Universidad de Chile, 2011)El objetivo general del presente trabajo de título fue desarrollar un tipo especial de juego, que funciona bajo dispositivos móviles de tipo PDA. Este proyecto nace como una manera de ayudar a atenuar los problemas de ...
-
(Universidad de ChileCyberDocs, 2010)El objetivo del presente trabajo de título es estudiar las implicancias de un modelo a tiempo continuo para juegos repetidos con información incompleta, con el objeto de estudiar la versatilidad y verosimilitud de este ...
-
(Society for Industrial and Applied Mathematics Publications, 2019)© 2019 Society for Industrial and Applied MathematicsThe method of asymptotic partial decomposition of a domain proposed and justified earlier for thin domains (rod structures, tube structures consisting of a set of thin ...
-
(Elsevier, 2016)In this paper we design a new implicit solver for the Junction-Generalized Riemann Problem (J-GRP),whichis based on a recently proposed implicit method for solving the Generalized Riemann Problem (GRP) for systems of ...
-
(1997)The El Faldeo is the southernmost Andean mineral district and consists of Paleozoic polymeta- morphic basement unconformably overlain by a 200 m thick homoclinal sequence of sedimentary and felsic volcanic beds of the ...
-
(2007)Jurassic to Early Cretaceous magmatism in the Coastal Cordillera of northern Chile is represented by thick sequences of mostly basaltic- and esitic to andesitic lava flows and minor sedimentary rocks. The volcanic sucession ...
-
(Oxford University Press, 2017)We present the discovery of K2-113, a dense hot-Jupiter discovered using photometry from Campaign 8 of theKepler-2 (K2) mission and high-resolution spectroscopic follow-up obtained with the FEROS spectrograph. The planet ...
-
(Oxford University Press, 2018)We present the discovery of K2-140b, a P = 6.57 d Jupiter-mass (M-P = 1.019 +/- 0.070 M-Jup) planet transiting a V = 12.5 (G5-spectral type) star in an eccentric orbit (e = 0.120(-0.046)(+0.056)) detected using a combination ...
-
(Oxford University Press, 2019)© 2018 The Author(s).We report the discovery of K2-161b, which was first identified as a planetary candidate from Kepler K2 photometry of Campaign 14, and whose planetary nature and orbital parameters were then confirmed ...
-
(Oxford University Press, 2018-06)We report the discovery of K2-232 b using photometric data of the Kepler K2 satellite coupled with ground-based spectroscopic observations. K2-232 b has a mass of M-P = 0.397 +/- 0.037 M-J, a radius of R-P = 1.00 +/- 0.020 ...
-
(Oxford University Press, 2018)We report the discovery of two hot Jupiters orbiting the stars K2-237 and K2-238. We used photometric data from Campaigns 11 and 12 of the Kepler K2 mission and radial velocity data obtained using the HARPS, FEROS, and ...
-
(Royal Soc Chemistry, 2018)A novel 2D metal oxalatophosphite, K2Mn2II(H2O)(2)C2O4(HPO3)(2) (KMnCP), was hydrothermally synthesized and characterized. The hexagonal morphology and crystal growth faces of KMnCP were predicted by the Bravais-Friedel- ...
