Arduino data-logger and artificial neural network to data analysis

Abstract

This work takes thermodynamic modelling through computer science for incubation process at domestic birds, that has presented energy consumption significantly high than energy used in processes. Thus, a data analysis was applied upon variables of temperature and relative humidity for heating zones, trying to know how much energy supplied by source was used, as well as, voltage and current variables are measured in the same moment that temperature and relative humidity are acquired. Then, data analysis was done using artificial neural networks models with samples obtained from sensors, where real process is highly time- variant, fixing environment conditions at the moment required. Therefore, with this system has been obtained an air flow of 3.4375 10−2 m3/J using a anemometer respect to electrical energy supplied by fans, giving 9.4818 W of average power using ceramics resistances, and testing an adaptive controller where its variables are fitted using equations obtained from data analysis. In contrast, colombian farmers have decreased economic conditions to maintain them productions due to free trade agreements implemented lastly, indeed this system was developed using open- source software and hardware to avoid costs in acquisition by licensing politicians or periodic subscription to a specific product developed by companies.

Análisis de curvas de covid-19 en Colombia utilizando ajuste por mínimos cuadrados

“…Utilizar ajuste de curvas por mínimos cuadrados es un método de modelado no lineal [10]. Desarrollar este método de manera computacional es acertado, ya que las herramientas tecnológicas han sido fundamentales en el avance de la ciencia en diferentes áreas del conocimiento tales como la electrónica [11], la visión artificial [12], la termodinámica [13] o, incluso, en contextos educativos [14], [15] y [16]. Lo anterior si se tiene en cuenta que estas permiten en poco tiempo efectuar comparaciones que llevan a la correcta elección de un modelo adecuado que describa los datos, así como nos proporciona elementos de juicio suficientes para la toma de decisiones en condiciones de incertidumbre [17].…”
