(National Academy of Sciences, 2017)A microeconomic theory-based multiple discrete-continuous choke model was developed to accommodate (a) both time allocation and goods consumption as decision variables in the utility function, (b) both time and money budget ...
-
(Springer, 2018)The MMH porphyry type copper-molybdenum deposit in northern Chile is the newest mine in the Chuquicamata District, one of largest copper concentrations on Earth. Mineralized Eocene-Oligocene porphyry intrusions are hosted ...
-
(Springer, 2018)We prove existence of Abrikosov vortex lattice solutions of the Ginzburg-Landau equations of superconductivity, with multiple magnetic flux quanta per fundamental cell. We also revisit the existence proof for the Abrikosov ...
-
(European Geosciences Union, 2018)The relative roles of statistical weather preprocessing and streamflow postprocessing in hydrological ensemble forecasting at short-to medium-range forecast lead times (day 1-7) are investigated. For this purpose, a regional ...
-
(Elsevier, 2018)The maximum entropy method (MEM) is a well known deconvolution technique in radio-interferometry. This method solves a non-linear optimization problem with an entropy regularization term. Other heuristics such as CLEAN are ...
-
(Elsevier, 2018)We study the relative efficiency of two mechanisms actually employed in large-scale public procurements, often for transportation projects such as roads, bridges and rapid transit systems. In the more common “bidding ...
-
(Institution of Engineering and Technology - IET, 2018)A novel method to characterise the efficacy and efficiency of different sequential Bayesian processor implementations is proposed. This method is based on concepts of probably approximately correct computation and information ...
-
(IEEE-INST Electrical Electronics Engineers INC, 2018)A new method for attack detection of smart grids with wind power generators using reservoir computing (RC) is introduced in this paper. RC is an energy-efficient computing paradigm within the field of neuromorphic computing ...
-
(American Chemical Society, 2018)This study evaluates the impact of industrially prepared TiO2 nanoparticles on the biological system by using an in vitro model of colon cancer cell lines (HCT116). Industrial synthesis of titanium oxide nanoparticles was ...
-
(EDP Sciences, 2018)Context. We report results from lithium abundance determinations using high resolution spectral analysis of the 107 metal-rich stars from the Calan-Hertfordshire Extrasolar Planet Search programme. Aims. We aim to set ...
-
(Elsevier, 2018)As globalization has expedited mobility of faculty across nations, faculty hiring is taking place at an international level. Institutions and governments often perceive hiring faculty who were trained in different countries ...
-
(Elsevier, 2018)This paper studies the effect of several inventory policies on the design of a distribution network for fast-moving items able to provide differentiated service levels in terms of product availability for several demand ...
-
Numerical simulation of scour around circular piles due to unsteady currents and oscillatory flows (Taylor & Francis, 2018)Numerical modeling of pile scour is performed due to the action of unsteady currents and oscillatory flow greens, using 3D Reynolds averaged Navier-Stokes (RANS) equations for the hydrodynamic description and the Exner ...
-
(American Physical Society, 2018)Weyl semimetals are a new paradigmatic topological phase of matter featuring a gapless spectrum. One of its most distinctive features is the presence of Fermi arc surface states. Here, we report on atomistic simulations ...
-
(Elsevier, 2018)This paper presents a new algorithm to find under-dense regions called voids inside a 2D point set. The algorithm starts from terminal-edges (local longest-edges) in a Delaunay triangulation and builds the largest possible ...
-
Analytical study of the response of reinforced concrete walls with discontinuities of flag wall type (Wiley, 2017)Slender walls with discontinuities at their bases, such as flag walls or walls with door openings or access, are common in Chilean practice because of the architectural requirements at facades, first floors, and underground ...
-
(American Meteorological Society, 2017)This study develops an objective method of identifying terrain-trapped airflows (TTAs) along the coast of Northern California and documenting their impact on orographic rainfall. TTAs are defined as relatively narrow air ...
-
(Universidad de Chile, 2017)El presente trabajo de título consistió en el estudio de la reacción de lixiviación de la calcopirita bajo condiciones no-oxidativas a una temperatura de 70 °C y atmosfera inerte (N2), con el objetivo de caracterizar la ...
-
(EDP Sciences, 2017)The mechanisms responsible for heating the extended atmospheres of early-M spectral-type supergiants are poorly understood. So too is the subsequent role these mechanisms play in driving the large mass-loss rates of these ...
-
(Elsevier, 2017)Solar energy technologies are a promising option to lower the greenhouse gas emissions of energy generation. Using solar technologies in energy-intensive industries located in arid climate zones is an attractive alternative ...
