Design of multi-layered radiative cooling structures using evolutionary algorithms
In this work we present a novel way to design thinfilm radiative cooling metamaterials based on genetic algorithms. Three simulations with different design constraints have been done, resulting in three structures that ... -
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ... -
Determining an optimal area to locate a biorefinery under economic and environmental criteria
Facilities location is a strategic decision which has to be carefully considered because it could involve the failure or success of a business. For that reason, anything that helps decision makers to facilitate their ... -
Development and validation of an automatic and intelligent system for medullation and average diameter evaluation to alpaca, llama and mohair fibers
The aim of this work was to develop and validate an automatic and intelligent system (based in artificial intelligence) capable of quantify and identify fibers, by type of medullation in 5 categories. This work was carried ... -
Development of a water flow and velocity optical fiber sensor for field testing
A water flow and velocity fiber optic sensor system was developed and tested. The sensing head was especially developed and ruggedized to measure velocities at different depths, in order to calculate the discharge in channels. -
Development of energy management strategies for the sizing of a fast charging station for electric buses
