Research In Advanced Nuclear Development And Planning, Michael Kuca Dec 2014

Research In Advanced Nuclear Development And Planning, Michael Kuca

Engineering

This project began as an examination of small and mini nuclear power plants as an emergent energy technology capable of sustained base-load power generation in northern climates. Literature review immediately demonstrated Alaska should remain current on small and mini nuclear power plants because commercial vendors are promoting their products to state leaders as certain solutions. Is Alaska prepared to receive, operate, and decommission advanced nuclear technology as an alternative to traditional hydrocarbon power plants? The graduate committee encouraged me to facilitate discussions with Alaska Center for Energy and Power (ACEP) leadership in reference to their 2010 study on small modular …

Biotic And Abiotic Influences On The Use Of Arctic Lakes By Fish And Loons, Trevor B. Haynes Dec 2014

Biotic And Abiotic Influences On The Use Of Arctic Lakes By Fish And Loons, Trevor B. Haynes

Fisheries

The particularly severe effects of climate change anticipated in the Arctic, accompanied by ongoing anthropogenic activities, necessitate proactive and knowledge-based management of the region's aquatic ecosystems. However, the paucity of information on the Arctic's aquatic environments hinders strategic or spatially-explicit management. In this dissertation, I examine the habitat use of poorly studied taxa of the Arctic Coastal Plain (ACP) of Alaska, including freshwater fishes and yellow-billed loons (Gavia adamsii). Distribution studies can be biased by false absences; therefore, I began by determining the detection probabilities of six fish species common to Arctic lakes for five gear types (Chapter 2). Variation …

Cordova Floating Ferry Dock, Andrew T. Metzger Dec 2014

Cordova Floating Ferry Dock, Andrew T. Metzger

INE Project Reports

This study began the evaluation of the Cordova floating ferry dock using the ANSYS AQWA software. The AQWA software models the effects of waves, wind and current on floating structures. Floating bodies are modeled as a point-mass with inertial and hydrostatic characteristics. As part of the study, the critical wave characteristic was defined. During the modeling it was found that AQWA can only model rigid bodies and that the Cordova floats experience a wide range of wave periods and directions. Consequently, AQWA requires adaptation to fully model the ferry dock at Cordova.

Leed Certification Of Campus Buildings: A Cost-Benefit Approach, Erin Ann Hopkins Dec 2014

Leed Certification Of Campus Buildings: A Cost-Benefit Approach, Erin Ann Hopkins

Seton Hall University Dissertations and Theses (ETDs)

No comprehensive study has been done within the higher education sector to see if Leadership in Energy and Environmental Design (LEED) certification makes sense economically. This study helps fill the gaps in the literature by providing construction costs and energy and water costs for a sample of campus LEED-certified buildings within the United States. Finding out if campus greening makes sense economically from a full lifecycle standpoint can help address possible upfront green premium barriers. This study found that there is an upfront green premium for LEED-certified campus buildings. However, when looking at LEED-certified campus buildings from a building lifecycle …

Hardware And Software Implementation Of A Low Power Attitude Control And Determination System For Cubesats, Jesse Frey Dec 2014

Hardware And Software Implementation Of A Low Power Attitude Control And Determination System For Cubesats, Jesse Frey

Engineering

In recent years there has been a growing interest in smaller satellites. Smaller satellites are cheaper to build and launch than larger satellites. One form factor, the CubeSat, is especially popular with universities and is a 10 cm cube. Being smaller means that the mass and power budgets are tighter and as such new ways must be developed to cope with these constraints. Traditional attitude control systems often use reaction wheels with gas thrusters which present challenges on a CubeSat. Many CubeSats use magnetic attitude control which uses the Earth's magnetic field to torque the satellite into the proper orientation. …

The Integrated Hydrologic And Societal Impacts Of A Warming Climate In Interior Alaska, Charles E. Jones Dec 2014

The Integrated Hydrologic And Societal Impacts Of A Warming Climate In Interior Alaska, Charles E. Jones

Engineering

In this dissertation, interdisciplinary research methods were used to examine how changes in hydrology associated with climate affect Alaskans. Partnerships were established with residents of Fairbanks and Tanana to develop scientific investigations relevant to rural Alaskans. In chapter 2, local knowledge was incorporated into scientific models to identify a socialecological threshold used to model potential driftwood harvest from the Yukon River. Anecdotal evidence and subsistence calendar records were combined with scientific data to model the harvest rates of driftwood. Modeling results estimate that between 1980 and 2010 hydrologic factors alone were responsible for a 29% decrease in the annual wood …

Using Experimental Design And Response Surface Methodology To Model Induced Fracture Geometry In Shublik Shale, Venkatasai Sri Poludasu Dec 2014

Using Experimental Design And Response Surface Methodology To Model Induced Fracture Geometry In Shublik Shale, Venkatasai Sri Poludasu

Engineering

The Triassic Shublik Formation of the Alaska North Slope is a world-class resource rock and has been identified as the major source of many of the conventional hydrocarbon accumulations on the North Slope, including Prudhoe Bay. Recent interest in the Shublik as a potential shale resource play has highlighted the need for robust hydraulic fracture modeling and simulation of the interval, but little geologic information is available because of the remote nature of the region and the complex character of the Shublik. In this study, a methodology was developed for identifying the critical variables needed for accurate planning of a …

Groundwater Dynamics In Degrading, Discontinuous Permafrost, Michelle L. Barnes Dec 2014

Groundwater Dynamics In Degrading, Discontinuous Permafrost, Michelle L. Barnes

Engineering

In regions impacted by permafrost, discontinuities are areas of possible connection between the supra- and sub-permafrost portions of an aquifer. Permafrost discontinuities influence the transport of contaminants in an aquifer, necessitating delineation of these discontinuities and their influence on groundwater flow. Means of identifying the locations of permafrost discontinuities have previously been limited to geophysical methods and the evaluation of well logs. In this study we use groundwater elevation trends and environmental tracers (e.g., stable isotopes and temperature) to evaluate the dynamics in a sulfolane-contaminated aquifer located in a region of discontinuous permafrost in the Interior of Alaska. Using tracers …

Performance Of Shallow Anchor In Ice-Rich Silt, Chuang Lin, N/A 林闯 Dec 2014

Performance Of Shallow Anchor In Ice-Rich Silt, Chuang Lin, N/A 林闯

Engineering

Shallow anchor systems have been widely used for decades due to their time and cost efficiency. Yet when it comes to cold regions like Alaska, new challenges caused by the harsh environment need to be resolved before they are used extensively in cold regions. One challenge associated with anchor installation could be the potential thawing of warm permafrost due to the grout mortar hydration, which might undermine the capacity of the anchor. Another challenge is that due to low temperature the grout may cure slower or not cure at all, which will also result in a significant decrease in the …

Changes In Extreme Hydroclimate Events In Interior Alaskan Boreal Forest Watersheds, Katrina Bennett Dec 2014

Changes In Extreme Hydroclimate Events In Interior Alaskan Boreal Forest Watersheds, Katrina Bennett

Engineering

The high latitude regions of the globe are responding to climate change at unprecedented magnitudes and rates. As the climate warms, extreme hydroclimate events are likely to change more than the mean events, and it is the extreme changes that present a risk to society, the economy and the environment of the north. The subarctic boreal forest is one of the largest ecosystems in the world and is greatly understudied with respect to hydroclimate extremes. Thus, defining a baseline for changing extremes is the first step towards planning and implementing adaptation measures to reduce risk and costs associated with the …

Mapping Thunder Sources By Inverting Acoustic And Electromagnetic Observations, J. F. Anderson, J. B. Johnson, R. O. Arechiga, R. J. Thomas Dec 2014

Mapping Thunder Sources By Inverting Acoustic And Electromagnetic Observations, J. F. Anderson, J. B. Johnson, R. O. Arechiga, R. J. Thomas

Geosciences Faculty Publications and Presentations

We present a new method of locating current flow in lightning strikes by inversion of thunder recordings constrained by Lightning Mapping Array observations. First, radio frequency (RF) pulses are connected to reconstruct conductive channels created by leaders. Then, acoustic signals that would be produced by current flow through each channel are forward modeled. The recorded thunder is considered to consist of a weighted superposition of these acoustic signals. We calculate the posterior distribution of acoustic source energy for each channel with a Markov Chain Monte Carlo inversion that fits power envelopes of modeled and recorded thunder; these results show which …

Molecular-Like Hierarchical Self-Assembly Of Monolayers Of Mixtures Of Particles, P. Singh, Md. Shahadat Hossain, S. K. Gurupatham, K. Shah, E. Amah, D. Ju, M. Janjua, S. Nudurupati, I. Fischer

Publications and Research

We present a technique that uses an externally applied electric field to self-assemble monolayers of mixtures of particles into molecular-like hierarchical arrangements on fluid-liquid interfaces. The arrangements consist of composite particles (analogous to molecules) which are arranged in a pattern. The structure of a composite particle depends on factors such as the relative sizes of the particles and their polarizabilities, and the electric field intensity. If the particles sizes differ by a factor of two or more, the composite particle has a larger particle at its core and several smaller particles form a ring around it. The number of particles …

An Empirical Investigation Of Factors Influencing It Professionals’ Knowledge Sharing Behavior In Organizations, Prasad Shambulinga Rudramuniyaiah

Dissertations

Knowledge management is important for competitive advantage in knowledge-based organizations. A critical aspect of managing knowledge is the knowledge sharing behavior of organizational members. A positive relationship between knowledge sharing and organizational performance has been widely supported in prior literature. The vast body of extant literature on knowledge sharing behavior has identified that individuals possess specialized knowledge which can be valuable to the organization, specifically when it is shared. Knowledge sharing behavior however is influenced by several factors which either facilitate or inhibit knowledge sharing among individuals in an organizational context. A better understanding and management of these factors would …
