(Universidad de Chile, 2019)Actualmente, se tienen desempeños dispares de los indicadores clave de rendimiento (KPI) de los operadores de la Superintendencia de Carguío y Transporte de Minera Centinela. Se necesita saber quiénes son los operadores ...
-
(Universidad de Chile, 2014)El lenguaje corporal es importante para comunicarse fluidamente con las personas. En el ámbito de la interacción con máquinas, existen sistemas para reconocer automáticamente gestos, pero confunden cuerpos de color similar ...
-
(Universidad de Chile, 2011)La ciencia de la computación cada vez está más cerca de nosotros, presente en diversos dispositivos, desde el computador de escritorio hasta nuestro celular, incluso en el portaretratos. Una de las tecnologías con gran ...
-
(Universidad de Chile, 2020)El estándar RDF, en conjunto con los distintos lenguajes y esquemas que lo extienden, permiten a las máquinas pasar de su antiguo rol de mensajero pasivo a uno más protagónico, donde las máquinas mismas procesan e intercambian ...

(MDPI, 2020)This paper proposes two solutions based on angle diversity receivers (ADRs) to mitigate inter-cell interference (ICI) in underground mining visible light communication (VLC) systems, one of them is a novel approach. A ...

(ELSEVIER, 2005-09-21)The objective of our study was to find the evidence of copper interaction in LTP, motivated by copper involvement in neurodegenerative illness, like Parkinson, Alzheimer and Amyotrophic Lateral Sclerosis, and we initiated ...
-
(UNIV CHICAGO PRESS, 2006-10-10)We present polarization maps of NGC 2071IR from thermal dust emission at 1.3 mm and from CO J = 2 -> 1 line emission. The observations were obtained using the Berkeley-Illinois-Maryland Association ( BIMA) array in the ...

Interferometric Mapping of Magnetic fields: The Alma view of the Massive star-forming clump W43-MM1 (IOP, 2016)Here, we present the first results from ALMA observations of 1 mm polarized dust emission toward the W43-MM1 high-mass star-forming clump. We have detected a highly fragmented filament with source masses ranging from 14 ...
-
(UNIV CHICAGO PRESS, 2008-03-20)We report millimeter interferometric observations of polarized continuum and line emission from the massive star-forming region G34.4. Polarized thermal dust emission at 3 mm wavelength and CO J = 1 -> 0 line emission were ...
-
(Universidad de ChileCyberDocs, 2012)El presente trabajo de título se enmarca en el proyecto “Estudio de factibilidad experimental de la interferometría heterodina infrarroja basada en fibra en Chile” y su objetivo es el acondicionamiento del primer experimento ...
-
(Springer New York LLC, 2019)We consider the problem of finding positive solutions of the problem Δu − λu + u 5 = 0 in a bounded, smooth domain Ω in ℝ 3 , under zero Neumann boundary conditions. Here λ is a positive number. We analyze the role of ...
-
(Taylor & Francis, 2009-10)In this work, we propose an inexact interior proximal-type algorithm for solving convex second-order cone programs. This kind of problem consists of minimizing a convex function (possibly nonsmooth) over the intersection ...
-
(Taylor & Francis, 2016)This paper is devoted to the study of a bundle proximal-type algorithm for solving the problem of minimizing a nonsmooth closed proper convex function subject to symmetric cone constraints, which include the positive orthant ...
-
(Springer New York LLC, 2018)In this article we are interested in interior regularity results for the solution μ∈∈ C(Ω¯) of the Dirichlet problem {μ=0inΩc,I∈(μ)=f∈inΩ where Ω is a bounded, open set and f∈∈ C(Ω¯) for all є ∈ (0, 1). For some σ ∈ (0, ...
-
(Birkhauser Verlag AG, 2019)Neuropathic pain is a complication of cancer and diabetes mellitus and the most commonly used drugs in the treatment of the diabetic neuropathic pain have only limited efficacy. The aim of this study was to evaluate the ...
-
(Springer, 2015)We consider the standing-wave problem for a nonlinear Schrödinger equation, corresponding to the semilinear elliptic problem − u + V(x)u = |u|p−1u, u ∈ H1(R2), where V(x) is a uniformly positive potential and p > 1. ...
-
(Elsevier, 2016)To expand the absorption of pure nanosized TiO2 to the visible light range for improving the photocatalytic efficiency necessary for industrial application, the way of doping different transition metals such as Mn, Co and ...
-
(EDP, 2021)We present the spectroscopic and photometric study of five intermediate-luminosity red transients (ILRTs), namely AT 2010dn, AT 2012jc, AT 2013la, AT 2013lb, and AT 2018aes. They share common observational properties and ...
-
(Wiley-Blackwell, 2015)I model the role of intermediaries in corruption and examine the effects of policy on the level of intermediated corruption, price of permits, and welfare. Intermediaries with a history of being honest earn higher premiums. ...
-
(Elsevier, 2018)Two new iminopyriridine ligands (1-2) and two new neutral Pd(II) complexes (4-5) were designed, synthesized and characterized by spectroscopic and spectrometric techniques. Molecular structures of compounds 1, 3 and 5 were ...
