(Copernicus, 2020)The description of the relationship between interplanetary plasma and geomagnetic activity requires complex models. Drastically reducing the ambition of describing this detailed complex interaction and, if we are interested ...
-
(Elsevier, 2020)With the growing amount of digital collections of visual CH data being available across different repositories, it becomes increasingly important to provide archaeologists with means to find relations and cross-correspondences ...
-
(Elsevier, 2020)In this study, amorphous carbon buffer layer containing nano-crystalline diamond grains was pre-deposited on single crystal silicon (Si) wafers. (100) oriented diamond films were prepared on the buffer layer by increasing ...
-
(Springer, 2020)This paper analyzes the procedure used by FIFA up until 2018 to rank national football teams and define by random draw the groups for the initial phase of the World Cup finals. A predictive model is calibrated to form a ...
-
(Universidad de Chile, 2019)En un centro de atención de salud, los procesos de prescripción de medicamentos e indicación de exámenes cuentan con diversos factores que pueden desencadenar en efectos negativos, tanto para los pacientes como para el ...
-
(Universidad de Chile, 2019)En el escenario actual realizar minería a cielo abierto se vuelve cada vez más complejo, por lo que cada vez cobra gran importancia capturar el mayor valor posible en etapas tempranas de un proyecto aumentando sus ...
-
(Cambridge Univ Press, 2020)In this paper, we are concerned with unbounded solutions of the singularly perturbed forced pendulum equation in the presence of friction, namely e(2)u(x)" e + sinue = e2a( t)ue + e2 beta(t)u e in (- L, L). Using a limiting ...
-
(MDPI, 2020)This paper proposes a fractional-order sliding mode controller (FOSMC) for the robust control of a nonlinear process subjected to unknown parametric disturbances. The controller aims to ensure optimal growth in photobioreactors ...
-
(Elsevier, 2020)Floating photovoltaic power plants are a quickly growing technology in which the solar modules float on water bodies instead of being mounted on the ground. This provides an advantage, especially in regions with limited ...
-
(Universidad de Chile, 2019)In two-dimensional systems, dissipative vortices are described by a complex Ginzburg-Landau equation (CGLE) which has a universal character and describes such different systems as fluids, superfluids, superconductors, ...
-
Fractional order controllers for throughput and product quality control in a grinding mill circuit (Elsevier, 2020)This paper presents the design and application of a multiple-input–multiple-output fractional order proportional-integral (MIMO FOPI) controller to a grinding mill circuit. The MIMO FOPI controller pa- rameters are tuned ...
-
(Oxford, 2020)Tidal encounters in star clusters perturb discs around young protostars. In Cuello et al., we detailed the dynamical signatures of a stellar flyby in both gas and dust. Flybys produce warped discs, spirals with evolving ...
-
(Universidad de Chile, 2019)En sistemas de alta montaña del norte grande de Chile, formados generalmente de rocas altamente mineralizadas, existen compuestos que poseen altas concentraciones, que a partir de procesos erosivos y/o de lixiviación, ...
-
(Elsevier, 2020)The Burrows-Wheeler Transform (BWT) has become since its introduction a key tool for representing large text collections in compressed space while supporting indexed searching: on a text of length n over an alphabet of ...
-
(Elsevier, 2020)Microbes have developed mechanisms to resist the host immune defenses and some elicit antitumor immune responses. About 6 million people are infected with Trypanosoma cruzi, the protozoan agent of Chagas' disease, the sixth ...
-
(Elsevier, 2020)Two approaches have traditionally been identified for developing artificial intelligence systems supporting decision-making: Machine Learning, which applies general techniques based on statistical analysis and optimization ...
-
(Universidad de Chile, 2019)Este estudio presenta la metodología y aplicación del método Rock Engineering System (RES) para la evaluación del diseño y construcción de bancos bermas en una Mina Cielo Abierto en Chile. El desarrollo del índice de ...
-
(Oxford University Press, 2020)This is an Erratum to the paper ‘Cooling in the shade of warped transition disks’ that was published in MNRAS, 486, L58-L62 (2019). The x-axis of Fig. 1 in the original version of the paper is incorrectly labeled, the ...
-
Energy management systems for microgrids: main existing trends in centralized control architectures (MDPI, 2020)This paper presents both an extensive literature review and a qualitative and quantitative study conducted on nearly 200 publications from the last six years (based on international experience and a top-down analysis ...
-
(MDPI, 2020)In recent years, different off-the-shelf solutions for the rapid control prototyping of power electronics converters have been commercialised. The main benefits of those systems are based on a fast and easy-to-use environment ...
