A Life Cycle Analysis Of Dod Expeditionary Waste Management Practices Using Simapro, David J. Chester
A Life Cycle Analysis Of Dod Expeditionary Waste Management Practices Using Simapro, David J. Chester
Theses and Dissertations
The United States (US) Department of Defense (DoD) is investigating improved municipal solid waste (MSW) management techniques. Current techniques tax already limited land and energy resources at contingency bases and impart additional logistical support requirements and personnel commitments. Seeking a solution to this growing problem, the DoD is investigating waste-to-energy (WTE) systems to reduce the volume of hazardous and non-hazardous solid wastes while generating low emissions. The current barriers to the acquisition and utilization of viable WTE technologies are the high capital and operating and maintenance (O&M) costs. Using the Life-Cycle Analysis (LCA) software SimaPro, the human health, environmental quality, …
An Analysis Of Built Environment Factors In Residences And The Associated Effects On Mental Health Symptoms Of United States Veterans, Cody J. Beemer
An Analysis Of Built Environment Factors In Residences And The Associated Effects On Mental Health Symptoms Of United States Veterans, Cody J. Beemer
Theses and Dissertations
Current awareness and statistics regarding negative mental health outcomes of United States Military and Veteran populations justify research into causes and methods to assist those afflicted. Growing academic research indicates connections between the built environment and the mental health of its occupants may be important. This research is intended to explore this relationship with a Veteran study group. Through the completion of a literature review, key built environment factors associated with various mental health conditions were identified. Mechanisms and pathways through which these factors can affect mental health conditions were explored. An analysis of residential built environment factors and Veteran …
Quantifying Permafrost Extent, Condition, And Degradation At Eielson Air Force Base, Theodore J. Labedz
Quantifying Permafrost Extent, Condition, And Degradation At Eielson Air Force Base, Theodore J. Labedz
Theses and Dissertations
The DoD is executing over $500M in military construction on Eielson Air Force Base (AFB) within the next three years. This construction program will expand the footprint of facilities and change parts of the storm water management scheme, which may have second order effects on the underlying permafrost layers. These changes in permafrost will drive engineering decision, and help shape the overall strategy for military readiness in the Arctic. Little site-specific knowledge exists on the human caused effects to permafrost at this location. In 2016, the permafrost degradation rates at Eielson AFB were modeled using the Geophysical Institute Permafrost Laboratory …
Virus Adsorption To Colloids In Water: Interactions Between Bacteriophage Ms2, Kaolinite, And Fiberglass, Ashlee N. Ellis
Virus Adsorption To Colloids In Water: Interactions Between Bacteriophage Ms2, Kaolinite, And Fiberglass, Ashlee N. Ellis
Theses and Dissertations
Virus adsorption to colloidal particles is an important issue in the water quality community, and it is a particularly important issue for conventional wastewater treatment plants that accept biohazardous waste. Colloids impact the transport of viruses in engineered treatment systems, and they also provide protection against oxidants and other destructive mechanisms. This study evaluated the adsorption of bacteriophage MS2 to colloidal suspensions of kaolinite (KAO) and fiberglass (FG). A series of laboratory batch tests were carried out over a range of experimental conditions to determine kinetic rate constants and characterize bond strength, and computational experiments were done to assess both …
Toxicological Life Cycle Impact Analysis Of Short And Long Chain Perfluorinated Compounds Compared To Impacts Of Treatment Techniques, Joshua R. Glass
Toxicological Life Cycle Impact Analysis Of Short And Long Chain Perfluorinated Compounds Compared To Impacts Of Treatment Techniques, Joshua R. Glass
Theses and Dissertations
Polyfluoroalkyl substances (PFAS) are man-made substances that are used as surfactants in industrial processes and commercial products most notably for the Air Force in aqueous film-forming foam. These compounds were introduced in the 1950s and have since become pervasive throughout industrial and consumer products such as carpet, leather, and paper as well as textiles that repel water, grease, and oils. As the presence of PFAS continues to grow, so do concerns for the toxicological impacts of exposure to these chemicals. Although there is much research into the toxicological impacts of PFAS, there are no regulatory treatment levels within the United …
Analyzing The Efficiency Of Horizontal Photovoltaic Cells At Air Force Installations In Various Climate Regions, Parker A. Hines
Analyzing The Efficiency Of Horizontal Photovoltaic Cells At Air Force Installations In Various Climate Regions, Parker A. Hines
Theses and Dissertations
The U.S. Air Force relies heavily on electrically powered facilities to ensure mission-critical capabilities can be carried out. Without a resilient electrical system in place, the U.S. Air Force could be without power for extended periods, resulting in severe implications. Installing a photovoltaic array on an installation is one strategy to improve energy resiliency. The amount of power a photovoltaic array can produce is reliant on its geographical location, position and weather characteristics. This research presents the development of novel linear regression models based upon 14 case studies from global Department of Defense (DoD) installations to predict horizontal photovoltaic power …
Modeling Power Output Of Horizontal Solar Panels Using Multivariate Linear Regression And Random Forest Machine Learning, Christil K. Pasion
Modeling Power Output Of Horizontal Solar Panels Using Multivariate Linear Regression And Random Forest Machine Learning, Christil K. Pasion
Theses and Dissertations
United States Air Force energy resiliency goals are aimed to increase renewable energy implementation among its facilities. Researchers at the Air Force Institute of Technology designed, manufactured, and distributed 37 photovoltaic test systems to Air Force installations around the world. This research uses two types of modeling techniques, multivariate linear regression and random forest machine learning, to determine which technique will better predict power output for horizontal solar panels. Many previous solar panel prediction studies use solar irradiation data as an input. This study does not use irradiation as an input and aims to predict power output with input variables …
Non-Intrusive Occupancy Detection Methods And Models, James C. Tyhurst
Non-Intrusive Occupancy Detection Methods And Models, James C. Tyhurst
Theses and Dissertations
Occupants in the built environment impact facility energy consumption and indoor air quality. Predicting the presence of occupants within the built environment can therefore be used to manage these factors while providing additional benefits in terms of emergency management and future space utilization. Detecting occupancy requires a combination of sensors and models to accurate assess data collected within facilities to predict occupancy. This thesis investigated occupancy detection through a non-invasive data collection sensors and model. Specifically, this thesis sought to answer two research questions examining the ability of a radial basis function to accurately predict occupancy when generated from data …
