Interleaved boost converter for power tracking of solar PV arrays
In this paper the advantages of an enhanced boost converter are utilized in a photovoltaic based energy system, in order to improve the efficiency and the output/input voltage gain. In addition, this circuit topology allows ... -
Simulation of high water-cut in tight oil reservoirs during cyclic gas injection
Data from a pilot test imply substantial water production after gas injection, which may impede oil production, but the underlying mechanisms are poorly understood. A compositional model is developed to study possible ... -
Proterozoic History of the Southern Half of the Mount Evans 7.5- Minute Quadrangle: Evidence for a CA. 1.4 Ga Orogenic Event in the Central Front Range, Colorado, The
The Proterozoic history of the southeastern margin of Laurentia, especially during the Mesoproterozoic, is not well defined. Several tectonic events occurred during this time. The first two events were the Paleoproterozoic ... -
APPLIED MACHINE LEARNING FOR MULTI-SENSORY ROBOT PERCEPTION
In recent years, advances in autonomous robotics have begun to transform how we work and live. Unmanned Aerial Vehicles (UAV) and Unmanned Ground Vehicles are helping us to deliver goods, conduct surveys of construction ... -
HYDROTHERMAL SOLUBILITY OF MONAZITE RARE EARTH ELEMENT ENDMEMBERS, THE
Monazite-(Ce), a light rare earth element (REE) phosphate, occurs as an accessory mineral in metamorphic, igneous, and sedimentary environments, and is a common ore mineral in hydrothermal REE deposits. The chemical ... -
PERFORMANCE AND COST-EFFECTIVENESS OF COMMERCIALLY AVAILABLE ADSORPTIVE TECHNOLOGIES FOR TREATMENT OF PER- AND POLY-FLUOROALKYL SUBSTANCES (PFAS) IMPACTED GROUNDWATER
Per- and polyfluoroalkyl substances (PFAS) are emerging environmental contaminants that have received significant recent attention due to their relatively common occurrence in the environment, recalcitrance in treatment ... -
ESTIMATING MINERAL DISTRIBUTION USING MACHINE LEARNING MODELS
Estimating mineral distribution is important in mine planning. In this research, we studied how to apply tensor completion methods to estimate mineral distribution from partial observations. This includes how to map a ... -
Impacts of Rare Earth Elements on Biological Wastewater Treatment Processes
Rare earth elements (REEs) underpin a host of technologies that are central to modern society, including portable electronics, renewable and clean energy components, medical devices, and military equipment. Obtaining ... -
EXTRACTING BIOLOGICAL INSIGHTS FROM SINGLE MOLECULE MEASUREMENTS OF PROTEIN CONFORMATIONAL DYNAMICS USING K-SVD ALGORITHM
The conformational changes that biological macro-molecules undergo play a crucial role in functionality. These changes are measurable at the single molecular level using a technique known as single molecule Förster resonance ... -
Regulation, Product Durability, and Market Process in Recycling Electronic Waste
This is a three-paper dissertation in fulfillment of the requirements of a Ph.D. in Mineral and Energy Economics at the Colorado School of Mines. It is set in a broader economic context surrounding electronic waste, with ... -
Time-Lapse Study of Microseismic Velocity and Reflection Imaging, A
The unconventional oil and gas industry is convinced that fractures are one of the main differentiators between a good and bad well. Though, fracture delineation within unconventional reservoirs still bares substantial ... -
HIDDEN MARKOV APPROACH FOR SCREENOUT DETECTION IN UNCONVENTIONAL RESERVOIRS, A
Hydraulic fracturing has gained its popularity all over the world as more tight geologic formations are developed economically for hydrocarbon resources. While exploring for new unconventional resources such as shale plays, ... -
Integrating big data analytics and cybersecurity for power distribution networks with distributed energy resources
The legacy electric power distribution system is designed primarily for unidirectional power flow from the electric grid made of large rotating electric machine-based generators located away from the load centers through ... -
Removal of arsenic and antimony from complex lead bullion via vacuum distillation, The
Vacuum distillation is based on the selective evaporation of volatile impurities from liquid melts and has been extensively studied. It is known to provide better operation conditions and a better control of product ... -
Design of a wireless energy harvesting system with a high polarization-purity circularly polarized array
As the search continues for alternate forms of energy sources, one that shows great promise and feasibility is wireless energy harvesting (WEH), which is the ability to harvest radio frequency (RF) energy from ambient ... -
Target-oriented imaging of acoustic media using unknown and uncontrolled random sources
Target-oriented imaging seeks to localize inhomogeneities within a medium from measurements of the waves that scatter off them. Conventionally, this requires both knowledge and control of the sources used to illuminate the ... -
Robot learning for loop closure detection and SLAM
Robotics and autonomy continues to be a key research and development focus around the world. Robots are increasingly prevalent in everyday life. From manufacturing, home cleaning, to self-driving vehicles, robots are an ... -
Terrestrial and satellite radar interferometry applications for ground deformation investigations in urban subsidence detection, landslide velocity monitoring, and novel failure discovery
The projects present interferometric radar measurements at high temporal resolutions and fine spatial precisions that allow new insights about ground deformation dynamics. The work is organized into three studies: (1) A ... -
Geology and geochemistry of the Kansanshi Cu-(Au) deposit, North-Western Province, Zambia
The Kansanshi Cu-(Au) mine exploits a structurally controlled deposit hosted by strongly deformed Neoproterozoic metasediments in the Katangan Basin of southern Africa. It is currently the largest active Cu mine in Africa, ... -
Fundamental electrochemical study on neodymium molten salt electrolysis in fluoride bath
In the recent decades, the clean energy economy has been driving a rapidly increasing demand for rare earth materials with their applications in essential high technologies such as electric vehicles and wind turbines. The ...
