Detección de prendas de vestir utilizando modelos de detección de objetos basados en deep learning (Universidad de Chile, 2020)El uso de herramientas de visión computacional ha tenido un fuerte impacto en la industria dadas sus variadas aplicaciones y su capacidad de automatización de complejos y demandan- tes procesos. Una de las industrias en ...
-
(Universidad de Chile, 2020)El objetivo de esta memoria es evaluar la factibilidad de reutilizar fibras de polipropileno que quedan del lavado de camiones de hormigón proyectado para ser ocupada nuevamente en el uso de hormigón en el Proyecto Minero ...
-
(Universidad de Chile, 2020)El presente trabajo de título se desarrolla en el Servicio de Salud Metropolitano Sur Oriente; el cual se encuentra realizando un proyecto de renovación y digitalización de la Programación Médica. Ésta última se entiende ...
-
(Universidad de Chile, 2020)La salud mental ha cobrado visibilidad en el último tiempo y es cada vez más relevante levantar información al respecto para tomar medidas tanto preventivas, como correctivas en todas las etapas de vida de las personas. ...
-
(Universidad de Chile, 2020)El agua es esencial para la vida, pero es un recurso limitado. Por lo que es necesario contar con un tratamiento que impida daños a la salud y a la vez sea aproveche el uso del agua. El trabajo de título tiene como objetivo ...
-
(Taylor & Fracis, 2020)Using a statistical approach, Scheihing attempts to demonstrate the direct influence of recharge events in the Precordillera and the Andean Piedmont on water table variations in downstream alluvial fans. The author ...
-
(Universidad de Chile, 2020)El estudio de avalanchas de roca es un campo con diversas dudas que responder, partiendo por los mecanismos de transporte que les permiten alcanzar grandes distancias desde la fuente, hasta la importancia de los factores ...
-
(Springer, 2020)Ride-hailing (ridesourcing) companies such as Uber, Lyft, and Didi Chuxing have been a disruptive force in the urban mobility landscape around the world during the past decade. In this paper, we analyse the working conditions, ...
-
(SIAM, 2020)We are concerned with the subdifferentials of integral functionals and functions given in the form E-f(x) = f(T) f (t, x)d mu, for a possibly nonconvex normal integrand f defined on a separable Banach with separable dual ...
-
(Springer, 2020)BiFeO3 was synthesized by conventional solid-state reaction method, and its structural, vibrational, electrical, ferroelastic, and multiferroic properties were studied. X-ray diffraction analysis and Rietveld refinement ...
-
(Springer, 2020)Two algorithms are proposed to simulate space-time Gaussian random fields with a covariance function belonging to an extended Gneiting class, the definition of which depends on a completely monotone function associated ...
-
(EDP Science, 2020)Context. Proxima Centauri is the closest star to the Sun and it is known to host an Earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radial velocities. At quadrature, ...
-
(Springer, 2020)The 2-dimension linguistic variables (2-DLVs) add a subjective evaluation on the reliability of the evaluation results provided by decision makers, so 2-DLVs are very useful tools for describing uncertain or fuzzy information. ...
-
(Elsevier, 2020)Solid lubricants like carbon-based materials, transition metal dichalcogenide compounds, polymers and soft metals, each with their specific merits and limitations, pursue the goal of reducing friction and wear between two ...
-
(IOS, 2020)This study proposes, through weighted averages and ordered weighted averaging operators, a new aggregation system for the investigation of average gases emissions. We present the ordered weighted averaging operators gases ...
-
(Oxford University Press, 2020)The rho Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the cosmic background imager (CBI). Here, we present 4.5 arcmin observations with CBI 2 that confirm 31 GHz emission from ...
-
(American Geophysical Union, 2020)The El Tatio geothermal field in the Chilean Altiplano contains hydrothermal silica sinter deposits overlaying glacial and volcanic units, providing an opportunity to constrain the timing of deglaciation and volcanic ...
-
(Desalination Publications, 2020)In this present work, two-step methods were executed to prepare TiO2/NiO nanocomposite material. The selected area electron diffraction and X-ray diffraction pattern were interpreted and their fallouts demonstrate the ...
