(Springer, 2021)Up to now, similitude methods have been used in order to overcome the typical drawbacks of experimental testing and numerical simulations by reconstructing the full-scale model behavior from that of the scaled model. The ...
-
(IEEE-Inst Electrical Electronics Engineers, 2021)The increasing integration of renewable energy sources into current power systems has posed the challenge of adequately representing the statistical properties associated with their variable power generation. In this paper, ...
-
(MDPI, 2021)In the last decades, the incorporation of copper in polymeric membranes for water treatment has received greater attention, as an innovative potential solution against biofouling formation on membranes, as well as, by its ...
-
(Nature, 2021)Of all the characteristics of a violin, those that concern its shape are probably the most important ones, as the violin maker has complete control over them. Contemporary violin making, however, is still based more on ...
-
(Hindawi, 2021)The vibrational behavior of composite structures has been demonstrated as a useful feature for identifying debonding damage. The precision of the damage localization can be greatly improved by the addition of more measuring ...
-
(Amer Inst Mathematical Sciences-AIMS, 2021)A linear system of di erence equations and a nonlinear perturbation are considered, we obtain su cient conditions to ensure the topological equivalence between them, namely, the linear part satis es a property of ...
-
(Ediciones Universidad de Murcia, España, 2021)Genres written by students have received significant attention due to its diversity of functions in subject learning. Thus, the present article is framed within the study field of academic genres in Spanish. The aim of ...
-
(MDPI, 2021)Seasonal snow and glaciers in arid mountain regions are essential in sustaining human populations, economic activity, and ecosystems, especially in their role as reservoirs. However, they are threatened by global atmospheric ...
-
(Copernicus Gesellschaft MBH, 2021)On 3 March 2020, the first case of COVID-19 was confirmed in Chile. Since then, the Ministry of Health has imposed mobility restrictions, a global policy implemented to mitigate the propagation of the virus. The national ...
-
(MDPI, 2021)In underground mining, the design of rock pillars is of crucial importance as these are structures that allow safe mining by maintaining the stability of the surrounding excavations. Pillar design is often a complex task, ...
-
(Public Library Science, 2021)By early May 2020, the number of new COVID-19 infections started to increase rapidly in Chile, threatening the ability of health services to accommodate all incoming cases. Suddenly, ICU capacity planning became a first-order ...
-
(IOP, 2021)We report the resistivity measured at temperatures between 5 K and 300 K of a Cu film 63 nm thick with grains that have a diameter d = 10.5 nm on the average. The resistivity of this film is described by the first quantum ...
-
(MDPI, 2021)The Atacama Desert receives the highest levels of solar irradiance in the world with an annual average of 2500 kWh/m(2) for the global horizontal irradiance and 3500 kWh/m(2) for the direct normal irradiance. One of the ...
-
(MDPI, 2021)This manuscript describes a method that is based on the implementation and setup of a mechatronic system that can recognize and detect, through thermal analysis, the zones where heap leaching piles may become locally ...
-
(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 ...
-
(Elsevier, 2021)In the present study, we depict the structural modification of test minerals, physiological response and ovarian damage in the tropical sea urchin Salmacis virgulata using microcosm CO2 (Carbon dioxide) perturbation ...
-
(Frontiers Media, 2021)Social policies are commonly defined from scattered knowledge. It is hard to find examples of social policy design based on a systemic perspective, and even harder with formal modeling support. To advance in filling this ...
-
(IEEE-Inst Electrical Electronics Engineers, 2021)Weakly supervised semantic segmentation (WSSS) methods have received significant attention in recent years, since they can dramatically reduce the annotation costs of fully supervised alternatives. While most previous ...
-
(MDPI, 2021)Small productive processes (SPPs) are promising drivers that promote the economic use of energy in microgrids (MGs). Both the complex nature of the SPPs and voltage variations make the operation of MGs challenging, since ...
-
(Korean Electrochemistry Society, 2021)Mo,Cu-doped CeO2 (CMCuO) nanopowders were synthesized by the nitrate-fuel combustion method aiming to improve the electrical and electrochemical properties of its Mo-doped CeO2 (CMO) parent by the addition of copper. An ...
