Study Of Artificially Disordered Optical Fibers, Herath Mudiyanselage Sumudu Rasika Kumari Herath

Doctoral Dissertations

"Light transmission through photo-sensitive multi-mode fibers (MMF) with controlled volume disorder is investigated. Experiment shows that a segment of disordered MMF as short as 10 cm is sufficient to distribute power uniformly over all co-propagating modes and the intensity at the output surface of the fiber follows the Rayleigh negative exponential function. To explain the experimental findings, a comprehensive theoretical model is developed with three main results. First, statistical properties of all components of the dielectric tensor are obtained and analyzed in the framework a microscopical model of photo-sensitivity in a germano-silicate glasses. Secondly, it is shown that induced birefringence …

Geochemical And Isotopic Characterization Of Lead In Fugitive Dust From Unsurfaced Roads In Missouri, Emitt C. Witt

Doctoral Dissertations

"Eighteen unsurfaced roadways in Missouri's rural Ozark region were sampled to characterize the differences in trace element and isotopic chemistry to determine if there is a human health concern with inhaling and/or ingestion of fugitive dust generated by a moving vehicle. Road reaches were selected to represent those in similar rural areas with and without the presence of mining activity--13 roads were selected in the Viburnum Trend (VT) resource mining area and five were located to the southwest of the mining areas. Samples were collected using a novel cyclonic fugitive dust sampler (patent pending) that collects a composite sample from …

Numerical Modeling Of Heat Transfer And Fluid Flow In Laser Metal Deposition By Powder Injection, Zhiqiang Fan

Doctoral Dissertations

"Laser metal deposition is an additive manufacturing technique which allows quick fabrication of fully-dense metallic components directly from Computer Aided Design (CAD) solid models. A self-consistent three-dimensional model was developed for the laser metal deposition process by powder injection, which simulates heat transfer, phase changes, and fluid flow in the melt pool, The governing equations for solid, liquid and gas phases in the calculation domain have been formulated using the continuum model. The free surface in the melt pool has been tracked by the Volume of Fluid (VOF) method, while the VOF transport equation was solved using the Piecewise Linear …

Compositional Diversity In The Atmospheres Of Hot Neptunes, With Application To Gj 436b, J. I. Moses, M. R. Line, Channon Visscher, M. R. Richardson, N. Nettleman, J. J. Fortney, T. S. Barman, K. B. Stevenson, N. Madhusudhan

Faculty Work Comprehensive List

Neptune-sized extrasolar planets that orbit relatively close to their host stars—often called "hot Neptunes"—are common within the known population of exoplanets and planetary candidates. Similar to our own Uranus and Neptune, inefficient accretion of nebular gas is expected produce hot Neptunes whose masses are dominated by elements heavier than hydrogen and helium. At high atmospheric metallicities of 10-10,000 times solar, hot Neptunes will exhibit an interesting continuum of atmospheric compositions, ranging from more Neptune-like, H₂-dominated atmospheres to more Venus-like, CO₂-dominated atmospheres. We explore the predicted equilibrium and disequilibrium chemistry of generic hot Neptunes and find that …

Chemistry Of Impact-Generated Silicate Melt-Vapor Debris Disks, Channon Visscher, Bruce Fegley Jr.

Faculty Work Comprehensive List

In the giant impact theory for lunar origin, the Moon forms from material ejected by the impact into an Earth-orbiting disk. Here we report the initial results from a silicate melt-vapor equilibrium chemistry model for such impact-generated planetary debris disks. In order to simulate the chemical behavior of a two-phase (melt+vapor) disk, we calculate the temperature-dependent pressure and chemical composition of vapor in equilibrium with molten silicate from 2000 to 4000 K. We consider the elements O, Na, K, Fe, Si, Mg, Ca, Al, Ti, and Zn for a range of bulk silicate compositions (Earth, Moon, Mars, eucrite parent body, …

Frameworks For Amending Reservoir Water Management, Ethan Mower, Leandro E. Miranda

Publications

Managing water storage and withdrawals in many reservoirs requires establishing seasonal targets for water levels (i.e., rule curves) that are influenced by regional precipitation and diverse water demands. Rule curves are established as an attempt to balance various water needs such as flood control, irrigation, and environmental benefits such as fish and wildlife management. The processes and challenges associated with amending rule curves to balance multiuse needs are complicated and mostly unfamiliar to non-US Army Corps of Engineers (USACE) natural resource managers and to the public. To inform natural resource managers and the public we describe the policies and process …

American Indian Water Rights, Michael Osborn, Darcy S. Bushnell

Water Matters!

Pueblos and tribal reservations are located within most of the larger stream systems in New Mexico. Each has claims to rights to use the water in its stream. In New Mexico, Indian rights are significant because of their early priority dates, because of the large amounts of water rights claimed, or both. In some instances, such claims have the potential to displace a significant number of junior water rights.

Common law theories or doctrines pertaining to Indians continue to be judicially refined and to evolve so that discussing the nature and extent of “Indian water rights” is a complex topic.

State And Regional Water Planning, Brigette Buynak, Susan Kelly, Sarah Armstrong

Water Matters!

A statewide water planning effort was initiated by the New Mexico legislature in the 2003 session. The Interstate Stream Commission (ISC),in collaboration with the Office of the State Engineer (OSE) and the Water Trust Board, was tasked with preparing and implementing a comprehensive state water plan. Regional water planning had begun much earlier, prompted by a lawsuit that El Paso filed against New Mexico in 1983, El Paso v. Reynolds.

The State Water Plan Act of 2003 (Act) was intended to promote stewardship of the state’s water resources and to establish clear policies and strategies for management of the state’s …

Deep Water Regulation, Paul Bossert, Kari Olson

Water Matters!

With most of the surface water in New Mexico fully appropriated and with groundwater sources being drawn down and becoming less reliable, the search for new sources of water is reaching further and further afield of traditional sources and methods. Water wells deeper than 2,000 feet have been rare due to the expense of deep drilling and the uncertainty of finding potable water. Yet the combined circumstances of advances in hydrology and the escalating demand for new water have driven the search for water deeper than was previously considered practical.

Water Marketing, Jeremy Oat, Laura Paskus

Water Matters!

Water doesn’t just flow around New Mexico in streams and rivers: it also moves around on paper. Since all of the state’s surface-water and most of its groundwater have already been allocated, the only way for cities, developers, or conservation organizations to find new water supplies is to buy and transfer water rights from old uses and places to new uses and places. The N.M. Office of the State Engineer (OSE) approves each of these transfers, most of which are relatively small, but the numbers can add up over time. Between 1982 and 2011, for instance, 21,000 acre-feet of Middle …

Las Voces De America: Reflecting On Mari Matsuda's Voice, Stories, And Analysis, Margaret E. Montoya

Faculty Scholarship

Professor Matsuda's exhortation to listen to people of color was certainly heard and seized by people of color. It spoke to me personally and inspired me as I was writing my first article, Mascaras, Trenzas y Grerias. Once the multiracial group of scholars that took the name "LatCrit" organized ourselves, we deliberately and intentionally centered our annual conferences around listening to the voices at the bottom, including the local activists in the cities in which we met. We listened to such voices as both method and substance.

You Can't Get There From Here: Elderly Prisoners, Prison Downsizing, And The Insufficiency Of Cost Cutting Advocacy, Elizabeth Rapaport

Faculty Scholarship

The prison population in the United States has peaked and begun to recede, reversing more than 30 years of growth. Mass incarceration is yielding to the imperative to reduce state budgets in recessionary times. As states turn away from the extravagant use of prison for nonviolent offenders, the percentage of the prison population serving long and life sentences for violent felonies will increase. By 2009 one in eleven prisoners were lifers. These are the prisoners growing old and dying in prison. High cost elderly prisoners who have aged out of crime should be good candidates for cost saving measures such …

Scattered And Dissonant: The Clean Air Act, Greenhouse Gases, And Implications For The Oil And Gas Industry, Alex Ritchie

Faculty Scholarship

In the midst of a domestic oil and gas production revolution, the Environmental Protection Agency (EPA) has constructed a web of findings and regulations to control greenhouse gas (GHG) emissions from stationary sources under the auspices of the Clean Air Act. This Article explores the theoretical and practical implications for the oil and gas industry of EPA’s Clean Air Act GHG regulatory regime that, in light of congressional paralysis, will continue to expand beyond major new and modified oil and gas facilities such as refineries and natural gas processing plants. Future rulemakings directly aimed at the oil and gas industry …

Addressing The Foreclosure Crisis Through Law School Clinics, Nathalie Martin, Max Weinstein

Faculty Scholarship

Since the 2008 financial crisis, unprecedented numbers of homes have been lost to foreclosure in the United States, all while public funds for free or reduced fee legal representation in some communities have all but disappeared. This means that most homeowners in foreclosure are unable to find lawyers to represent them. At the same time, clinical legal education, especially in subjects related to business and commercial law, is on the rise. This convergence offers a unique opportunity for law school clinics to give students valuable training in both litigation and financial law and also help fill the deep need for …
