(Universidad de Chile, 2006)El propósito de la presente investigación es estudiar y desarrollar modelos flexibles, versátiles y eficientes, estadísticamente y económicamente significativos, para proyectar la variación futura del precio de la Plata. ...
-
(Universidad de Chile, 2013)En el presente estudio se evaluaron tres modelos para predecir el signo de la variación del IPSA, los cuales fueron regresión lineal, Support Vector Machines (SVM) y redes neuronales utilizando el software de data mining ...
-
(Wiley, 2015)To carry out functional simulations of the masticatory system that aim to predict strain magnitudes it is important to apply appropriate jaw-elevator muscle forces. Force magnitude estimation from directly measured muscle ...
-
(Nature, 2020)Applications from finance to epidemiology and cyber-security require accurate forecasts of dynamic phenomena, which are often only partially observed. We demonstrate that a system's predictability degrades as a function ...
-
(Elsevier Inc., 2018)Hotspots are generated by partial melting due to hot plumes rising within the Earth's mantle, and when tectonic plates move relative to the plume source, hotspot tracks form. Off South America, the oceanic Nazca Plate hosts ...
-
(2010-04)Influenza AH1N1 severely affected the population of Chile. It has high transmissibility, which may stress the health system capacity. An adequate prediction of number of cases and frequency of complications is needed. ...
-
(Universidad de Chile, 2021)Diversos estudios han mostrado que la variabilidad del clima a escala decadal en Chile se encuentra influenciada tanto por forzantes externos del sistema climático como por variabilidad interna que perturba el estado medio ...
-
(Universidad de Chile, 2015-01)Existe una profunda la discusión en el mundo de las finanzas sobre la efectividad del análisis técnico y del análisis fundamental, a la hora de predecir los precios de los activos y obtener retornos por sobre el mercado. ...
-
(Wiley, 2015)The recognition that growing proportions of species worldwide are endangered has led to the development of comparative analyses to elucidate why some species are more prone to extinction than others. Understanding factors ...
-
(Pergamon-Elsevier, 2016)Accurate characterization of two phase bubbly flows is crucial in many industrial processes such as fluidized reactors, ore froth flotation, etc. The bubble size determines the rate at which components present in the gas ...
-
(Springer Nature, 2020)We aimed to develop and validate classification models able to identify individuals at high risk for transition from a diagnosis of depressive disorder to one of bipolar disorder. This retrospective health records cohort ...
-
(American Chemical Society, 2020)An alchemical transformation is any process, physical or fictitious, that connects two points in the chemical space. A particularly important transformation is the vanishing of a proton, whose energy can be linked to the ...
-
(Springer, 2020)Shifts in species distributions are among the observed consequences of climate change, forcing species to follow suitable environmental conditions. Using species distribution models (SDMs), we aimed at predicting trends ...
-
(Wiley, 2015)Biological traits explain extinction at the species level, but what factors explain collapse at the ecosystem level? Using ecosystem Red List criteria from the International Union for Conservation of Nature, we calculated ...
-
Predicting effects of ecosystem engineering on species richness along primary productivity gradients (ELSEVIER, 2010)Physical ecosystem engineering is the process by which some species change the distribution of materials and energy in ecosystems. Although several studies have shown that this process is a driver of local species ...
-
(Springer, 2022)Non-dimensional similarity groups and analytically solvable proximity equations can be used to estimate integral fluid film parameters of elastohydrodynamically lubricated (EHL) contacts. In this contribution, we demonstrate ...
-
(Emerald Group Publishing, 2013)Purpose – Twitter is a popular microblogging service which has proven, in recent years, its potential for propagating news and information about developing events. The purpose of this paper is to focus on the analysis ...
-
(SAGE, 2020)The obesity epidemic progresses everywhere across the globe, and implementing frequent nationwide surveys to measure the percentage of obese population is costly. Conversely, country-level food sales information can be ...
-
(Elsevier, 2020)Soil physical properties influence vineyard behavior, therefore the knowledge of their spatial variability is essential for making vineyard management decisions. This study aimed to model and map selected soil properties ...
-
(IEEE-Inst Electrical Electronics Engineers, 2021)Predicting an individual's risk of getting a stroke has been a research subject for many authors worldwide since it is a frequent illness and there is strong evidence that early awareness of having that risk can be bene ...
