Expanding Faculty-Student Interactions In Statics: An Exploratory Study Of A Statics Course With Learning Assistants, Valerie V. Bracho Perez

FIU Electronic Theses and Dissertations

Statics is one of the first fundamental engineering classes within the ME undergraduate curriculum, in which a student’s performance in the course can impact their overall academic success. Recent efforts to enhance students learning in fundamental engineering courses have included integrating Learning Assistants (LAs), undergraduate peers who have previously excelled in the course, into the instructional team of the course. The purpose of this Master's thesis is to explore the enactment of a Statics classroom with LAs, the interactions that characterize it, and the impact it has on the students and instructional teams. A qualitative case study of a Statics …

Management Optimization Of Energy Consumption Reduction For Residential Hot Water, Francesco Cataldi

FIU Electronic Theses and Dissertations

The objective of this thesis is to create an automatic water management system capable of optimizing the usage of warm water stored in two water tanks to reduce the monthly energy consumption of the instant water heater installed in a residential house. This system is called Water Mixing System (WMS). The two heat sources considered are: PV-T system and heat rejected by the air condition system. The PV-T system is a new technology that allows transformation of the sun radiation into both electricity and warm water, increasing the efficiency of the panel compared to either a common photovoltaic panel or …

Heat-Driven Self-Cooling System Based On Thermoelectric Generation Effect, Robel Kiflemariam

FIU Electronic Theses and Dissertations

This research entails the first comprehensive and systematic study on a heat-driven, self-cooling application based on the thermoelectric generation effect. The system was studied using the first and second laws of thermodynamics to provide a solid and basic understanding of the physical principles governing the system. Multiphysics equations that relate heat transfer, fluid dynamics and thermoelectric generation are derived. The equations are developed with increasing complexity, from the basic Carnot heat engine to externally and internally irreversible engines. A computational algorithm to systematically use the fundamental equations has been presented and computer code is implemented based on the algorithm.
