CFD-Based Multi-Objective Optimization of a Cyclone Separator Using Response Surface Methodology, NSGA-II, and Physical Prototype Validation

Cyclone separators are widely used for gas–solid separation; however, improving separation efficiency generally increases pressure drop, making cyclone design a challenging multi-objective optimization problem. This study aims to optimize a high-efficiency Stairmand cyclone separ...

Crossing into Mestizaje? Interethnic Households and Intergenerational Ethnic Identification in Ecuador

Official statistics treat ethnic self-identification as a fixed trait. This study examines which youths do not reproduce the ethnic category of their household of origin and instead identify as mestizo, the unmarked category of Ecuador’s national ideology of mestizaje. Using the...

Sustainable Pest Management in Peri-Urban Andean Agroecosystems: Integrating Ecotype Selection, Chemical Control, and Environmental Impact Assessment for Tree Tomato (Solanum betaceum) Production

The bacterial pathogen Candidatus Liberibacter solanacearum (CLso), transmitted by the potato psyllid Bactericera cockerelli, causes purple tip disease, a major threat to tree tomato (Solanum betaceum) production in peri-urban Andean highlands. This study evaluated an agroecologi...

IoT System for Level Monitoring and Control with Point-to-Point LoRa Between Siemens S7-1200 PLCs

Industrial supervision can be expanded through the Internet of Things (IoT) without moving the control logic outside the PLC. This study evaluates a level-monitoring and control architecture using a point-to-point LoRa link between two Siemens S7-1200 PLCs; LoRaWAN is used solely...
