(American Geophysical Union, 2020)Imaging silicic systems using geophysics is challenging because many interrelated factors (e.g., temperature, melt fraction, melt composition, geometry) can contribute to the measured geophysical anomaly. Joint interpretation ...
-
(Elsevier, 2017)The mining sector in Chile is facing a steady increase of energy consumption, which is mainly explained by the lower grades, the increase in rock hardness, and deeper mines. Although much of the mining activity in Chile ...
-
(Elsevier, 2020)One of the most common methods used in the social network analysis of criminal groups is node importance evaluation, which focuses on the links between network members to identify likely crime suspects. Because such ...
-
(GRAZ UNIV TECHNOLGOY, 2008)Advances in wireless communication and mobile computing extend collaboration scenarios. Mobile workers using computing devices are currently able to collaborate in order to carry out productive, educational or social ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2011-06)Urban transit demand exhibits peaks in time and space, which can be efficiently served by means of different fleets, increasing frequencies in those groups of stops with larger passenger inflow. In this paper we develop a ...
-
(Elsevier Ltd, 2019)Chile is one of the first documented nations to undergo a forest transition dominated by tree farm expansion. Scenario modelling can inform the possible outcomes of forest conservation policies, especially when the scenarios ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-02)Starting from explicit expressions for the subdifferential of the conjugate function, we establish in the Banach space setting some integration results for the so-called epi-pointed functions. These results use the ...
-
(Frontiers Media, 2020)Acidithiobacillus thiooxidansis one of the most studied biomining species, highlighting its ability to oxidize reduced inorganic sulfur compounds, coupled with its elevated capacity to live under an elevated concentration ...
-
Integration of crosswell seismic data for simulating porosity in a heterogeneous carbonate aquifer (Elsevier, 2013)A challenge for the geostatistical simulation of subsurface properties in mining, petroleum and groundwater applications is the integration ofwell logs and seismic measurements,which can provide information on ...
-
(2007)Combining conditional probabilities based on logratios is considered and compared with other integration models. Each data set is at first treated separately and merged with considering data source redundancies. Permanence ...
-
(Universidad de Chile, 2015)Esta tesis es acerca de modelos de localización e inventarios con niveles de servicio diferenciados para productos de alta rotación. La motivación detrás de esta tesis es el trabajo desarrollado por más de 10 años en el ...
-
(Hekdermann, 2016)We extend the results of Correa, Garcia and Hantoute [6], dealing with the integration of nonconvex epi-pointed functions using the Fenchel subdifferential. In this line, we prove that the classical formula of Rockafellar ...
-
(IEEE-Inst Electrical Electronics Engineers, 2022)Small productive processes (SPPs) have recently emerged as attractive alternatives to contribute to the socio-economic development of communities, primarily in rural contexts. However, SPPs have a complicated electrical ...
-
(Universidad de Chile, 2011)El siguiente es un proyecto realizado para Hewlett-Packard Chile, filial de HP Company, la cual vende productos de computación y ofrece servicios y soluciones tecnológicas. La empresa se divide funcionalmente en Imagen e ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020)In this paper, we propose intelligent reflecting surfaces (IRS) assisted secure wireless communications with multi-input and multi-output antennas (IRS-MIMOME). The considered scenario is an access point (AP) equipped with ...
-
(Universidad de Chile, 2020)La seguridad de los usuarios viales vulnerables (VRUs por su sigla en inglés) es crítica dada su exposición. Se espera que la integración de VRUs en redes de comunicación vehicular mejore su seguridad. Sin embargo, la ...
-
(American Association for the Advancement of Science, 2014)The subduction zone in northern Chile is a well-identified seismic gap that last ruptured in 1877. The moment magnitude (Mw) 8.1 Iquique earthquake of 1 April 2014 broke a highly coupled portion of this gap. To understand ...

Intensidades Sísmicas del Terremoto del 27 de Febrero del 2010 en las 34 Comunas del Gran Santiago (Universidad de ChileCyberDocs, 2011)El 27 de febrero del 2010 la zona centro-sur del país fue afectada por un terremoto de magitud Mw 8.8 con epicentro en el mar chileno frente a las costas de la VII Región. Producto de este terremoto se produjeron daños en ...
-
(Wiley, 2020)The Irtysh River is the main water resource of Eastern Kazakhstan and its upper basin is severely affected by spring floods each year, primarily as a result of snowmelt. Knowledge of the large-scale processes that influence ...
-
(Springer-Verlag, 2015)Crucial aspects of a strong thermally-driven wind system in the Atacama Desert in northern Chile during the extended austral winter season (May-September) are studied using 2 years of measurement data from the Sierra Gorda ...
