(Wiley, 2020)The analysis of network robustness tackles the problem of studying how a complex network behaves under adverse scenarios, such as failures or attacks. In particular, the analysis of interdependent networks' robustness ...
-
(Springer, 2020)Based on a time-use model with a sound theoretical basis and carefully collected data for Austria, the value of leisure (VoL) for different population segments has been estimated. Through the combination of these results ...
-
(Structural Chemistry, 2020)Derivatives of parent molecules possess similar structural activity which makes them to be the topic of equal interest. In the present work, a naturally occurring acid eugenol and its co derivatives allyl-2-methoxy-4-nitrophenol ...

(Universidad de Chile, 2020)Chile es uno de los países con mayor segregación escolar de la OCDE (OCDE (2018)). El nuevo Sistema de Admisión Escolar (SAE), que se ha implementado gradualmente desde 2015, busca orientar el sistema hacia uno más ...
-
(Universidad de Chile, 2020)El siguiente trabajo tiene por objetivo diseñar y optimizar un panel tipo sándwich para evitar la propagación de ondas mecánicas en el plano del material. Este sándwich estará confeccionado en su núcleo por un material ...

(Universidad de Chile, 2019)El margen litoral a lo largo del norte de Chile exhibe un imponente acantilado costero, que se extiende por c. 1.000 km entre Arica y Chañaral (18,5° - 26,30°S). El acantilado está limitado hacia el oeste por la rasa ...
-
(Universidad de Chile, 2020)Una de las interrogantes más importantes en la astronomía Galáctica es entender los procesos responsables de la formación y evolución de la Vía Láctea. La mayor parte de la información para estudiar las etapas tempranas ...
-
(Universidad de Chile, 2020)La presente tesis tiene como objetivo entregar una solución tecnológica que permita soportar la detección automática de publicidad en segmentos de video. Esta solución permitirá cuantificar de forma automatizada la ...
-
(Universidad de Chile, 2020)Las Tecnologías de la Información y Comunicación junto con el Internet de las Cosas, son las herramientas que hoy en día están siendo utilizadas cada vez con mayor frecuencia, sobretodo en el sector industrial, para ofrecer ...
-
(EDP Sciences, 2020)We present 22 new transit observations of the exoplanets WASP-18Ab, WASP-19b, and WASP-77Ab, from the Transit Monitoring in the South project. We simultaneously model our newly collected transit light curves with archival ...
-
(Universidad Complutense de Madrid, 2020)La crisis económica del 2008, cuyos peores efectos se percibieron en los países desarrollados, reavivó la disputa política por la hegemonía ideológica. Con ella se evidenció la disfunción existente entre bienes materiales ...
-
(Springer, 2020)We give new characterizations for the subdifferential of the supremum of an arbitrary family of convex functions, dropping out the standard assumptions of compactness of the index set and upper semi-continuity of the ...
-
(Institute of Electrical and Electronics Engineers, 2020)Motivated from the fact that universal source coding on countably infinite alphabets (infinity-alphabets) is not feasible, this work introduces the notion of "almost lossless source coding". Analog to the weak variable-length ...
-
(EDP Sciences, 2020)Context. RX J1604.3-2130A is a young, dipper-type, variable star in the Upper Scorpius association, suspected to have an inclined inner disk, with respect to its face-on outer disk. Aims. We aim to study the eclipses to ...
-
(Elsevier, 2020)Renewable energy systems are now accepted to be mandatory for climate change mitigation. These systems require a higher material supply than conventional ones. Particularly, they require more copper. The production of this ...
-
(EDP Sciences, 2020)Aims. Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear.Methods. We present an "end-to-end" approach that introduces sources of bias in a modelled weak ...
-
(IOP, 2020)We compare the observed turbulent pressure in molecular gas, P-turb, to the required pressure for the interstellar gas to stay in equilibrium in the gravitational potential of a galaxy, P-DE. To do this, we combine arcsecond ...
-
(Oxford University Press, 2020)We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V = -19.95 +/- 0.08, this object is one of the brightest Type II SNe, and lies in the gap of magnitudes ...
