Synthesis And Characterization Of Graphene-Family Mesoporous Nanomaterials For Themal Energy Harvesting And Sensing Applications, Romney Meek
Masters Theses & Specialist Projects
Graphene-family nanomaterials (GFNs) have attracted a great deal of attention both in academia and in industry for a range of applications relevant for homeland security. In this thesis, an array of graphene-based hybrid materials and aerogels are synthesized for use as novel thermo-electrochemical energy harvesters and for ascorbic acid biosensing devices. The graphene-family nanomaterials include graphene oxide-GO, thermally reduced GO-rGOth, nitrogenated functionalized graphene-NFG, graphene aerogel-GA, nitrogen-doped graphene aerogel-NGA, multi-walled carbon nanotube aerogel-MWCNT, single-walled carbon nanotube aerogel-SWCNT, graphene and nanotube combined ‘hybrid’ aerogels-Gr:(SW/MW)CNT of various ratios, along with multilayered nanostructured architectures such as gold (AuNP) and silver nanoparticles (AgNP) decorated NFG …
A Climatology Of Convective And Non-Convective High-Wind Events Across The Eastern United States During 1973-2015, Victoria Murley
A Climatology Of Convective And Non-Convective High-Wind Events Across The Eastern United States During 1973-2015, Victoria Murley
Masters Theses & Specialist Projects
High-wind events (HWE) occur across every region of the United States (U.S.) and result in hundreds of fatalities, as well as thousands of dollars in damages annually. HWEs are classified as sustained high-winds or high-wind gusts and can be generated from convective or non-convective weather systems. This study investigates high-wind observations across the eastern U.S. during a 43-year climatological period (1973-2015) for spatial and temporal variations in wind speed and direction. Hourly surface wind observations were gathered from the National Centers for Environmental Information Data Center Integrated Surface Database (NCEI-ISD). This dataset includes qualitycontrolled wind observations from 391 first-order weather …
Using Mobile Eye-Tracking To Inform The Development Of Mass Tourism In Iceland Towards The Principles Of Ecotourism, James Tyler Graham
Using Mobile Eye-Tracking To Inform The Development Of Mass Tourism In Iceland Towards The Principles Of Ecotourism, James Tyler Graham
Masters Theses & Specialist Projects
Since the late 20th century, nature-based tourism, an alternative to mass tourism with a focus on natural environments, has steadily grown in popularity. Nature-based tourism areas are considered a platform for informal education and exemplify principles of environmental stewardship and conservation. Iceland, an island nation in the North Atlantic, is one area of the world that has seen dramatic growth in its nature-based tourism industry in recent years; tourists are drawn to Iceland in numbers five times the total population of the Country. The pressures of economic development have resulted in the continued promotion of Icelandic tourism, and, subsequently, the …
Policy Communication And The Influence Of Agricultural Communities On Karst Landscapes: A Case Study In Phong Nha-Kẻ Bàng National Park, Vietnam, Elizabeth Willenbrink
Policy Communication And The Influence Of Agricultural Communities On Karst Landscapes: A Case Study In Phong Nha-Kẻ Bàng National Park, Vietnam, Elizabeth Willenbrink
Masters Theses & Specialist Projects
Karst landscapes are vulnerable to human influence, especially agricultural practices. The interconnectedness between surface activities and subsurface environments make karst landscapes particularly susceptible to soil erosion and water contamination. The likelihood of these two phenomena happening increases when agricultural intensification, irrigation, or fertilizer application occurs. This situation arises frequently in Vietnam, where 18% of the country is karst terrain and 60% of the population depends on agriculture for their livelihoods (Farming First 2009). In order to mitigate the negative consequences of agriculture on karst landscapes, effective implementation of policy to regulate human activities and increased communication of these policies to …
The Influence Of A Proposed Margin Criterion On The Accuracy Of Parallel Analysis In Conditions Engendering Underextraction, Justin M. Jones
The Influence Of A Proposed Margin Criterion On The Accuracy Of Parallel Analysis In Conditions Engendering Underextraction, Justin M. Jones
Masters Theses & Specialist Projects
One of the most important decisions to make when performing an exploratory factor or principal component analysis regards the number of factors to retain. Parallel analysis is considered to be the best course of action in these circumstances as it consistently outperforms other factor extraction methods (Zwick & Velicer, 1986). Even so, parallel analysis could benefit from further research and refinement to improve its accuracy. Characteristics such as factor loadings, correlations between factors, and number of variables per factor all have been shown to adversely impact the effectiveness of parallel analysis as a means of identifying the number of factors …
Investigating The Influence Of Esri Story Map Design On Partcipation In Sustainability-Related Activities, Brittany Grace Austin
Investigating The Influence Of Esri Story Map Design On Partcipation In Sustainability-Related Activities, Brittany Grace Austin
Masters Theses & Specialist Projects
Decades of scientific inquiry have conveyed evidence in support of sustainability efforts to mitigate some of the greatest challenges and dilemmas facing modern and future societies. The solutions to these dilemmas may not be achievable in the short-term, yet, through increased public participation in sustainable community development, smallscale, localized solutions can be obtained. This preliminary research explored the influence of Environmental Systems Research Institute (Esri) story map designs on participation in sustainability-related activities among individuals who expressed interest in sustainable lifestyles. Specifically, this exploratory study was designed to demonstrate the applicability of interactive web geographic information systems (GIS) applications as …
