Energy, environment, and sustainability: a hierarchical analysis of south Louisiana
… a general introduction. Chapter 2 calculates the energy return on financial investment (EROFI) of oil and gas production in the ultra-deepwater Gulf of Mexico (GoM) in 2009 and the Macondo Prospect (Mississippi Canyon Block 252). I calculated a preliminary Energy Return on Investment (EROI) using …

Development of GHG-Mitigation Oriented Models for the Planning of Integrated Energy-Environment Systems (IEES) Under Uncertainties
Energy-related activities are a major contributor of anthropogenic greenhouse gas (GHG) emissions. The mitigation of GHG emissions should thus be incorporated within the framework of integrated energy-environment systems (IEES) planning. However, various uncertainties and dynamics of the systems …

Phononic metamaterials based on complex geometries : "a new kind of metamaterial"
Facing the growing challenges of energy, environment, security and disease treatment, the demand for novel materials are growing. While the material centric approach have resulted in development of new materials for advanced applications, we introduce a geometric approach as a complementary point …
