Using Systems Architecture and the EVDT Framework for Monitoring Methane Emissions in Rio de Janeiro
Methane is a powerful greenhouse gas that has important implications for climate change. Over the past decade, satellites have rapidly improved their ability to detect this gas from above the atmosphere. This Thesis uses two Systems Engineering frameworks, Systems Architecture and EVDT, to examine …

CFD modeling of a tailgate ventilation condition in a longwall bleeder system
… lead to a major mine explosion. Despite having methane monitoring systems mounted on the shearer and at various locations on the longwall face, undetected methane accumulations can still occur and result in face ignitions. With the use of Computational Fluid Dynamics (CFD), the interaction …

Application of Background Oriented Schlieren (BOS) in Underground Mine Ventilation
… data about airflows in complex areas and methane emissions from coal. The acquisition of such data would not only enhance the understanding of mine ventilation but also improve the accuracy of ventilation surveys. As an example, surveys can benefit from small scale BOS investigations …

Laser Remote Sensing for Environmental Monitoring
… sensing and their applications in environmental monitoring, as documented in several published papers. The environment where the human being live is degrading with an accelerating speed. Quantitative monitoring characterizes the quality of the environment and offers possibilities to solve …
