• Modelo empírico de Angström-Prescott para estimar la radiación solar en Norte de Santander, Colombia 

      Contreras Sepulveda, Wilmer; Galban Pineda, Migan Giuseppe; Bustos Marquez, Luis Fernando; Sepúlveda, Sergio; Ramirez Mateus, Jhon Jairo (Revista de Investigación Desarrollo e Innovación: RIDIColombia, 2021-02-15)
      The document shows the application of the empirical Angström-Prescott model in different places in Norte de Santander, Colombia. The model estimates solar radiation from hours of sunlight, at a site ...
    • Making the case for time-of-use electric rates to boost the value of battery storage in commercial buildings with grid connected PV systems 

      Sepúlveda, Sergio; Hegedus, Steven S. (EnergyReino Unido, 2021-03-01)
      We performed a techno-economic analysis of behind-the-meter photovoltaics (PV) coupled with lithium-ion battery storage under a flat rate and a time-of-use (TOU) rate for commercial buildings using HOMER Grid software. ...
    • Experimental development of fuzzy controllers for thermal and pneumatic processes 

      Hernández Mesa, Richard Samir; MORENO GARCIA, FRANCISCO ERNESTO; Castro Casadiego, Sergio; Medina Delgado, Byron (Ingeniería y CienciaColombia, 2021-05-12)
      In this project, a Fuzzy control system is proposed in an industrial process training module with two independent systems between them, one thermal and the other pneumatic. The control algorithm is developed in Python ...
    • Adaptive nodes algorithm to solve the orphan nodes problem in a ZigBee Tree WSN 

      Escobar Amado, Christian David; Celis, Jose Miguel; Sepúlveda, Sergio; Castro Casadiego, Sergio ; Medina Delgado, Byron; Guevara, Dinael (IngeniareChile, 2021-06)
      We have developed an algorithm based on hybrid nodes composed of an XBee S2C module configured in API mode with escape and connected to a microcontroller ATMEGA 328P to solve the orphan node problem of a ZigBee tree ...
    • Implementation of an automated dryer with solar collector 

      Regino Ubarnes, fernando Jesús; Jaramillo, H Y; Moreno Garcia, F E Moreno-Garcia2 (Journal of Physics: Conference SeriesReino Unido, 2022-01-10)
      This research work consists of the development of an automated sustainable drying system using forced and preheated air to reduce the production time of handmade bricks, so a dryer witha solar collector wasimplemented ...
