Agriculture is considered as one of the most essential activities for human beings, mainly because food is obtained through it. With the aim of increasing production and improving the state of food and even the health of farmers, different robots have started to be used, in what is currently known as precision agriculture. With this purpose the Cer...
This paper investigates the performance of an artificial neural network (ANN) model in predicting the energy absorption capacity (g) of ultra-high-performance fiber reinforced concrete (UHPFRC) under direct tensile test. To avoid overfitting a data division into test and training datasets was carried out. Thereafter the neural networks were trained...
From a set of numerical measurements of the speed V and the direction E of the wind, the basic definitions were established to obtain the wind energy model in a promising geographic region using the estimators (A,U,Θ) on the parameters K abd C of a Weibull Distribution. Based on a combinatorial optimization approach and using the Exhaustive Search ...
The rum aging process shows volume losses, called wastage. The numerical operation variables: product, boardwalk, horizontal and vertical positions, date, volume, alcoholic degree, temperature, humidity and aging time, recorded in databases, contain valuable information to study the process. MATLAB 2017 software was used to estimate volume losses. ...
The objective of the project is to identify moments of argumentation in the development of modeling in math classes. To do this, we implemented a mathematical modeling task in a 2nd year high school course (15-16 years old) in a partially subsidized private establishment in Santiago. The 90-minute class was analyzed by characterizing the argumentat...
RESUMEN Esta investigación propuso un modelo de red neuronal artificial con entrenamiento dinámico para predecir las temperaturas de salida de ambos fluidos en un sistema de intercambiadores de calor para monoetanolamina, realizando el entrenamiento, validación y pruebas con 31 680 juegos de datos obtenidos a través del método de experimentación pa...
Actualmente el empleo de las máquinas eléctricas como los generadores, motores, transformadores, máquinas síncronas o asíncronas se desarrollan por los distintos sectores y procesos industriales conocidos, por lo que es indispensable realizar modelamientos de éstas para el correcto funcionamiento, así como la detección de fallas a tiempo, entre otr...
Tourism in Postconflict Colombia: Environmental Impacts and Contributions to Local Development. The end of the armed conflict between the Revolutionary Armed Forces of Colombia and the Colombian government in 2016 has meant an impulse of tourism, making it to become one of the economic activities that contributes most to the country's economy, espe...
The study presented aims to model the flexural behavior of ultra-high-performance fiber reinforced concrete (UHPFRC), i.e. limit of proportionality (LOP), modulus of rupture (MOR) and theirs associated deflections δMOR and δLOP, using multivariable regression analyses and artificial intelligence (AI) techniques. Four Artificial Neural Network (ANN)...
Resumen La ciudad de Bogotá, Colombia, se ha visto inmersa en problemas de inundaciones por empozamientos de agua pluvial y aumento tanto en la temperatura promedio como en la contaminación del aire. Las tecnologías verdes representan un mecanismo para la mitigación de tales problemas. Esta investigación analiza el comportamiento de la inundación u...
