River Restoration: Institutions, Boundaries, And Social Ecological Dynamics, Eileen Sylvan Johnson Dec 2015

River Restoration: Institutions, Boundaries, And Social Ecological Dynamics, Eileen Sylvan Johnson

Electronic Theses and Dissertations

This human dimensions research, consisting of three manuscripts, explores the social and ecological dimensions of river restoration through an examination of the restoration trajectories of the Androscoggin, an impaired system, and the Kennebec, a restored system. Manuscript one examines the influence of biophysical and community attributes and institutional rules on policy stakeholders goals and actions within the two watersheds. For manuscripts one and two, we conducted semi-structured interviews with key informants, assembled documents pertaining to restoration actions, and conducted participant observation at stakeholder meetings. We qualitatively analyzed transcripts and documents. Results suggest that policy stakeholders’ understandings of biophysical and community ...


Simulation Of An Air Cooled Single-Effect Solar Absorption Cooling System With Evacuated Tube Collectors, Mohsen Jahandardoost Dec 2015

Simulation Of An Air Cooled Single-Effect Solar Absorption Cooling System With Evacuated Tube Collectors, Mohsen Jahandardoost

UNLV Theses/Dissertations/Professional Papers/Capstones

Consistently increasing CO2 emission and ozone depletion from synthetic refrigerants are serious environmental issues challenging the scientific community. Absorption cooling systems give scope of utilizing low grade energy source for generating cooling effect. Solar energy is one of these low grade energy sources and with considering the fact that cooling demand increases with the intensity of solar radiation, solar refrigeration has been considered as a logical solution.

This thesis consists of two different simulation stages, in the first stage, a single effect lithium bromide absorption cooling system with constant cooling capacity is modeled and the effect of ambient and generator ...


The Number Of Zeros Of A Polynomial In A Disk As A Consequence Of Coefficient Inequalities With Multiple Reversals, Derek T. Bryant Dec 2015

The Number Of Zeros Of A Polynomial In A Disk As A Consequence Of Coefficient Inequalities With Multiple Reversals, Derek T. Bryant

Electronic Theses and Dissertations

In this thesis, we explore the effect of restricting the coefficients of polynomials on the bounds for the number of zeros in a given region. The results presented herein build on a body of work, culminating in the generalization of bounds among three classes of polynomials. The hypotheses of monotonicity on each class of polynomials were further subdivided into sections concerning r reversals among the moduli, real parts, and both real and imaginary parts of the coefficients.


Predicting Intraday Financial Market Dynamics Using Takens' Vectors; Incorporating Causality Testing And Machine Learning Techniques, Abubakar-Sadiq Bouda Abdulai Dec 2015

Predicting Intraday Financial Market Dynamics Using Takens' Vectors; Incorporating Causality Testing And Machine Learning Techniques, Abubakar-Sadiq Bouda Abdulai

Electronic Theses and Dissertations

Traditional approaches to predicting financial market dynamics tend to be linear and stationary, whereas financial time series data is increasingly nonlinear and non-stationary. Lately, advances in dynamical systems theory have enabled the extraction of complex dynamics from time series data. These developments include theory of time delay embedding and phase space reconstruction of dynamical systems from a scalar time series. In this thesis, a time delay embedding approach for predicting intraday stock or stock index movement is developed. The approach combines methods of nonlinear time series analysis with those of causality testing, theory of dynamical systems and machine learning (artificial ...

Constraint Answer Set Programming Versus Satisfiability Modulo Theories Or Constraints Versus Theories, Yuliya Lierler, Benjamin Susman Oct 2015

Constraint Answer Set Programming Versus Satisfiability Modulo Theories Or Constraints Versus Theories, Yuliya Lierler, Benjamin Susman

Yuliya Lierler

Constraint answer set programming is a promising research direction that integrates answer set programming with constraint processing. This research direction often informally relates itself to the field of Satisfiability Modulo Theory. Yet the exact formal link is obscured as the terminology and concepts used in these two research fields differ. The goal of this paper to make the link between these two fields precise.

Performance Tuning In Answer Set Programming, Matt Buddenhagen, Yuliya Lierler Sep 2015

Performance Tuning In Answer Set Programming, Matt Buddenhagen, Yuliya Lierler

Yuliya Lierler

Performance analysis and tuning are well established software engineering processes in the realm of imperative programming. This work is a step towards establishing the standards of performance analysis in the realm of answer set programming -- a prominent constraint programming paradigm. We present and study the roles of human tuning and automatic configuration tools in this process. The case study takes place in the realm of a real-world answer set programming application that required several hundred lines of code. Experimental results suggest that human-tuning of the logic programming encoding and automatic tuning of the answer set solver are orthogonal (complementary) issues.

On The Brink: The Melting Of Earth’S Polar Ice Caps, Stephanie Kelley Sep 2015

On The Brink: The Melting Of Earth’S Polar Ice Caps, Stephanie Kelley

Kaleidoscope

Research indicates that earth’s polar ice caps are melting at a faster rate than ever before, a product of continued global warming. Unfortunately, side effects of this melting may negatively impact the lives of humans who dwell on this planet. Consequences may include: a significant loss of albedo, a considerable rise in sea levels, damage to aquatic ecosystems, and/or an ice age resulting from the shutdown of major oceanic currents. Although the situation is not yet imminent and the causes not yet pinpointed, the present outlook is too grim to ignore.

Geometric Constructions From An Algebraic Perspective, Betzabe Bojorquez Sep 2015

Geometric Constructions From An Algebraic Perspective, Betzabe Bojorquez

Electronic Theses, Projects, and Dissertations

Many topics that mathematicians study at times seem so unrelated such as Geometry and Abstract Algebra. These two branches of math would seem unrelated at first glance. I will try to bridge Geometry and Abstract Algebra just a bit with the following topics. We can be sure that after we construct our basic parallel and perpendicular lines, bisected angles, regular polygons, and other basic geometric figures, we are actually constructing what in geometry is simply stated and accepted, because it will be proven using abstract algebra. Also we will look at many classic problems in Geometry that are not possible ...

Evaluating Sub-Lethal Effects Of Orchard-Applied Pyrethroids Using Video-Tracking Software To Quantify Honey Bee Behaviors, Erin M. Ingram, Julie Augustin, Marion D. Ellis, Blair Siegfried Sep 2015

Evaluating Sub-Lethal Effects Of Orchard-Applied Pyrethroids Using Video-Tracking Software To Quantify Honey Bee Behaviors, Erin M. Ingram, Julie Augustin, Marion D. Ellis, Blair Siegfried

Faculty Publications: Department of Entomology

Managed honey bee, Apis mellifera L., colonies are contracted to pollinate fruit and nut orchards improving crop quality and yield. Colonies placed in orchards are potentially exposed to pyrethroid insecticides used for broad-spectrum pest control. Pyrethroids have been reported to pose minimal risk to bees due to their low application rates in the field and putative repellent properties. This repellency is believed to alter foraging behavior with the benefit of preventing bees from encountering a lethal dose in the field. However, sub-lethal exposure to pyrethroids may adversely impact bee behavior potentially resulting in social dysfunction or disruption of foraging.

Environmental Issues In The 1995 Farm Bill, P. G. Lakshminarayan, Bruce A. Babcock Aug 2015

Environmental Issues In The 1995 Farm Bill, P. G. Lakshminarayan, Bruce A. Babcock

Iowa Ag Review

The perception is growing that U.S. agricultural policy has reached a major turning point increased trade opportunities with GATT, a continued decline in rural population, increased budgetary (fiscal) pressure, and growing environmental concerns are among the primary reasons. Because of these trends, nontraditional interest groups representing urban and environmental interests will play an increasingly important role in shaping future farm legislation.


Implications Of Extending The Consertation Reserve Program For Iowa, John R. Kruse Aug 2015

Implications Of Extending The Consertation Reserve Program For Iowa, John R. Kruse

Iowa Ag Review

A variety of alternatives have recently been proposed for the future of the Conservation Reserve Program (CRP) program. Among the proposals are: elimination of the program, targeting specific land types for reentry into the program, allowing renewal of all contracts, and redefining the program to bid land in for a one lime permanent easement payment.


The Conservation Reserve Program, John R. Kruse Aug 2015

The Conservation Reserve Program, John R. Kruse

Iowa Ag Review

The Conservation Reserve Program (CRP) was originally created in the 1985 Food Security Act to "assist owners and operators of highly erodible cropland in conserving and improving the soil and water resources of their farms or ranches."

Late Quaternary Speleogenesis And Landscape Evolution In A Tropical Carbonate Island: Pango La Kuumbi (Kuumbi Cave), Zanzibar, Nikos Kourampas, Ceri Shipton, William Mills, Ruth Tibesasa, Henrietta Horton, Mark Horton, Mary Prendergast, Alison Crowther, Katerina Douka, Patrick Faulkner, Llorenç Picornell, Nicole Boivin

International Journal of Speleology

Kuumbi Cave is one of a group of caves that underlie a flight of marine terraces in Pleistocene limestone in eastern Zanzibar (Indian Ocean). Drawing on the findings of geoarchaeological field survey and archaeological excavation, we discuss the formation and evolution of Kuumbi Cave and its wider littoral landscape. In the later part of the Quaternary (last ca. 250,000 years?), speleogenesis and terrace formation were driven by the interplay between glacioeustatic sea level change and crustal uplift at rates of ca. 0.10-0.20 mm/yr. Two units of backreef/reef limestone were deposited during ‘optimal’ (highest) highstands, tentatively ...

The near future of ethanol production in Iowa appears to be on safer footing than it was just a few weeks ago, but nothing is certain given the political volatility in Washington.


The Agricultural Footprints On The Environment, Philip Houtz Aug 2015

The Agricultural Footprints On The Environment, Philip Houtz

Kaleidoscope

Industrialized agricultural systems have given America a convenient and affordable means to supply a surplus of food products to its citizens. Transgenic technology, synthesized fertilizers, advanced pesticides, concentrated animal feeding operations (CAFOs), and the use of farm machinery have all contributed to humanity’s ability to feed the world’s rapidly growing population. However, the energy-intensive food operation of today may not be as ideal as we assume. Fossil fuels are burned to meet the energy requirements for the continual production of large quantities of fertilizer and to keep farm machines operational. Fertilizer and pesticide runoff from farmland ultimately drains ...


Morphology And Morphometry Of Double Layered Ejecta Craters On Mars, Ryan Schwegman Aug 2015

Morphology And Morphometry Of Double Layered Ejecta Craters On Mars, Ryan Schwegman

Electronic Thesis and Dissertation Repository

Double layered ejecta (DLE) craters display two distinct layers of ejecta that appear to have been emplaced as a mobile, ground-hugging flow. While volatile content within the target, atmosphere, or some combination of the two is generally considered a major variable enhancing the mobility of ejecta, the presence of unconsolidated surface materials may also have some effect. This statement is studied further here, aiming to determine whether bulk target lithology and/or attributes of the surface have any effect on morphometric properties between DLEs situated on sedimentary targets to those on volcanic ones. Results suggest that ejecta mobility (the distance ...


The Look Of The "New" Conservation Reserve Program, Steven L. Elmore, Darnell B. Smith Aug 2015

The Look Of The "New" Conservation Reserve Program, Steven L. Elmore, Darnell B. Smith

Iowa Ag Review

In recent years some prognosticators envisioned that the amount of acreage enrolled in the Conservation Reserve Program (CRP) would shift from west to east. This expectation is based on a perceived increase in the social valuation for water quality versus other CRP benefits. Some west-to-east shifts did occur after CRP rules were revised under the 1990 Farm Bill. However. the latest sign-up results reveal the opposite- an east-to-west movement.
