Drying Kinetics of Organic Parchment Coffee Beans (Coffea Arabica L.) Using a Fluidised Bed: a Semi Theoretical Microwave Modeling
(Universidad de MedellínFacultad de IngenieríasMedellín, 2020-10-23)The aim of this study was to model the drying kinetics of microwave and fluidised bed of parchment coffee beans (Coffea arabica L.) using a semi-theoretical approach. A completely randomized design with six treatments: ... -
Thermal Characteristics of TIO2 Nanocomposite in a Polyurethane Matrix Made with Castor Oil
(Universidad de MedellínFacultad de IngenieríasMedellín, 2020-10-23)Nanocomposites are multiphase structures with at least one pase dimension of nanometric order size. Polymer-based materials mixed with low proportions of titanium dioxide nanoparticles (NPs-TiO2) are a versatile alternative ... -
Monitoring of Fine Particulate Matter and Black Carbon, in Micro-Environments of Manizales Andean City: Pilot Study
(Universidad de MedellínFacultad de IngenieríasMedellín, 2021-10-22)Manizales has an air quality network which measure particulate matter (PM) in ambient air concentrations. However, this monitoring system does not have information of pollutant concentrations in the vicinity of roads. The ... -
A Look at Algorithm BEPtoPNST
(Universidad de MedellínFacultad de IngenieríasMedellín, 2021-09-09)This work analyzes the computational complexity of algorithm BEPtoPNST which transforms a building-evacuation problem (BEP) into a time-expanded, process-network synthesis (PNST) problem. The solution of the latter is ... -
Monitoring of Earth's Crust Movements Associated to Earthquakes through GPS Observations in the Gulf of California
(Universidad de MedellínFacultad de IngenieríasMedellín, 2021-09-04)The distribution of the velocities of the Pacific and North American plates and their possible alteration by earthquakes has been studied using the GPS continuous measurements in the lapse from 2010 to 2016. The GPS data ... -
