-
(Elsevier, 2018)Centralized energy auctions for long-term contracts are commonly-used mechanisms to ensure supply adequacy, to promote competition, and to protect retail customers from price spikes in Latin America. In Chile, the law ...
-
(Springer, 2018)This work presents strategies for fractional order model reference adaptive control (FOMRAC) and fractional order proportional-integral-derivative control (FOPID) applied to an automatic voltage regulator (AVR). The paper ...
-
(Elsevier, 2018)This research aims to explore public views and social attitudes toward the use of geothermal energy as a heating and electricity source in an area where the geothermal energy production technology has yet to be widely ...
-
(Elsevier, 2018)Thermal properties and microstructure characterization of Yttria Stabilized Zirconia (YSZ) Thermal Barrier Coatings (TBCs) deposited by Air Plasma Spray (APS) onto a Ni-base superalloy (Inconel 625) were studied. Two ...
-
(Oxford University Press, 2018)We have derived from VIMOS spectroscopy the radial velocities for a sample of 71 stars selected from CFHT/Megacam photometry around the Galactic globular cluster NGC 7492. In the resulting velocity distribution, it is ...
-
(Oxford University Press, 2018)We present Dark Energy Camera imaging for the peculiar Galactic globular clustersNGC 1851, NGC1904 (M 79), NGC2298 and NGC2808. Our deep photometry reveals that all the clusters have an important contribution of stars ...
-
(Oxford University Press, 2018)We study a sample of 28 S0 galaxies extracted from the integral field spectroscopic (IFS) survey Calar Alto Legacy Integral Field Area. We combine an accurate two-dimensional (2D) multicomponent photometric decomposition ...
-
(Elsevier, 2018)The Manantiales Foreland Basin, located at similar to 32 degrees 15'S in the Frontal Cordillera, Argentina, contains the sedimentary record of erosion of igneous basement and Miocene volcanic rocks exhumed during the Andean ...
-
(Elsevier, 2018)The outer rise is a topographic bulge seaward of the trench at a subduction zone that is caused by bending and flexure of the oceanic lithosphere as subduction commences. The classic model of the flexure of oceanic ...
-
(Oxford University Press, 2018)We present new data of the protoplanetary disc surrounding the Herbig Ae/Be star HD 169142 obtained in the very broad-band (VBB) with the Zurich imaging polarimeter (ZIMPOL), a sub-system of the Spectro-Polarimetric ...
-
(IOP Publishing Ltd, 2018)We present Atacama Large Millimeter Array observations at an angular resolution of 0 ''.1-0 ''.2 of the disk surrounding the young Herbig Ae star MWC. 758. The data consist of images of the dust continuum emission recorded ...
-
(Nature Publishing Group, 2018)Supermassive black holes reside in the nuclei of most galaxies. During their active episodes, black holes are powered by accretion discs where gravitational energy is converted into radiation(1). Accurately determining ...
-
(Universidad de Chile, 2017)La identificación de husos sigma se realiza manualmente por expertos en la medicina del sueño. El proceso consiste en inspeccionar el electroencefalograma (EEG) de los registros polisomnográficos y marcar los intervalos ...
-
(IOP Publishing Ltd, 2018)The low dust temperatures (< 14 K) of Planck Galactic cold clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. "TOP-SCOPE" is a joint survey program targeting ...
-
(IOP Publishing Ltd, 2018)We report the discovery of four short-period extrasolar planets transiting moderately bright stars from photometric measurements of the HATSouth network coupled to additional spectroscopic and photometric follow-up ...
-
(Universidad de Chile, 2017)Mina Rafaela corresponde a una explotación de un yacimiento que posee ciertas características que lo asemejan a un estratoligado de cobre y plata. Se encuentra ubicado en el sector de Peñablanca, al Suroeste de Cabildo ...
-
(Universidad de Chile, 2017)El objetivo general de este trabajo de título es estudiar la variabilidad del consumo máximo diario de oxígeno en el reactor biológico de un sistema de tratamiento de lodos activados para determinar factores de requerimiento ...
-
(Universidad de Chile, 2017)La División El Teniente de Codelco posee dentro de su cartera de proyectos el Nuevo Nivel Mina, el cual estará pre-acondicionado con fracturamiento hidráulico (FH), con el objetivo de facilitar la explotación del mineral ...
-
(Universidad de Chile, 2017)En este trabajo de título se estudiará la ingeniería conceptual de sistemas de transmisión colectores para la integración de generación de Energías Renovables No Convencionales (ERNC), considerando únicamente la energía ...
-
(Universidad de Chile, 2017)La penetración de energías renovables no convencionales en la matriz energética del país ha tenido un gran aumento, en especial las tecnologías solar fotovoltáica y eólica, lo que plantea grandes desafíos en la operación ...
