Single And Multi-Date Landsat Classifications Of Basalt To Support Soil Survey Efforts, Jessica J. Mitchell, Rupesh Shrestha, Carol A. Moore-Ellison, Nancy F. Glenn

Geosciences Faculty Publications and Presentations

Basalt outcrops are significant features in the Western United States and consistently present challenges to Natural Resources Conservation Service (NRCS) soil mapping efforts. Current soil survey methods to estimate basalt outcrops involve field transects and are impractical for mapping regionally extensive areas. The purpose of this research was to investigate remote sensing methods to effectively determine the presence of basalt rock outcrops. Five Landsat 5 TM scenes (path 39, row 29) over the year 2007 growing season were processed and analyzed to detect and quantify basalt outcrops across the Clark Area Soil Survey, ID, USA (4,570 km²). The …

Plant Community Composition And Structure Monitoring In Scotts Bluff National Monument, 2013 Annual Report, Isabel Ashton, Michael Prowatzke

United States National Park Service: Publications

Introduction

During the last century, much of the prairie within the Northern Great Plains has been plowed for cropland, planted with non-natives to maximize livestock production, or otherwise developed, making it one of the most threatened ecosystems in the United States. Within Nebraska, greater than 77% of the area of native mixed grass prairie has been lost since European settlement (Samson and Knopf 1994). The National Park Service (NPS) plays an important role in preserving and restoring some of the last pieces of intact prairies within its boundaries. The stewardship goal of the NPS is to “preserve ecological integrity and …

An Analysis Of The Impact Of Storage Temperature, Moisture Content & Duration Upon The Chemical Components & Bioprocessing Of Lignocellulosic Biomass, Arun Athmanathan

Open Access Dissertations

The successful utilization of lignocellulosic biomass as a feedstock for fuels and chemicals necessitates storage for 2-6 months. It is correspondingly important to understand the impact of storage parameters - moisture concentration, temperature and duration - on biomass quality.

As aerobic storage is the most viable large-scale solution, aerobic storage experiments were carried out with three projected bioenergy feedstocks - sweet sorghum (Sorghum bicolor) bagasse, corn (Zea mays) stover and switchgrass (Panicum virgatum). Stored samples of each were examined for dry matter loss and composition change to develop a material balance around carbohydrates and lignin.

A mean dry matter loss …

Stellar bars can lead to gas inflow toward the center of a galaxy and stimulate nuclear star formation. However, there is no compelling evidence on whether they also feed a central supermassive black hole: by measuring the fractions of barred active and inactive galaxies, previous studies have yielded conflicting results. In this paper, we aim to understand the lack of observational evidence for bar-driven active galactic nucleus (AGN) activity by studying a sample of 41 nearby (d < 35 Mpc) barred galaxies from the Spitzer Survey for Stellar Structure in Galaxies. We use Chandra observations to measure nuclear 2–10 keV X-ray luminosities and estimate Eddington ratios, together with Spitzer 3.6 μm imaging to quantify the strength of the stellar bar in two independent ways: (1) from its structure, as traced by its ellipticity and boxiness, and (2) from its gravitational torque Qb, taken as the maximum ratio of the tangential force to the mean background radial force. In this way, rather than discretizing the presence of both stellar bars and nuclear activity, we are able to account for the continuum of bar strengths and degrees of AGN activity. We find nuclear X-ray sources in 31 out of 41 galaxies with median X-ray luminosity and Eddington ratio of LX = 4.3×1038 erg s−1 and Lbol/LEdd = 6.9×10−6, respectively, consistent with low-luminosity AGN activity. Including upper limits for those galaxies without nuclear detections, we find no significant correlation between any of the bar strength indicators and the degree of nuclear activity, irrespective of galaxy luminosity, stellar mass, Hubble type, or bulge size. Strong bars do not favor brighter or more efficient nuclear activity, implying that at least for the low-luminosity regime, supermassive black hole fueling is not closely connected to large-scale features.

Quantified H I Morphology – Vii. Star Formation And Tidal Influence On Local Dwarf H I Morphology., Benne W. Holwerda, N. Pirzkal, W. J. G. De Blok, S. -L. Blyth

Faculty and Staff Scholarship

Scale-invariant morphology parameters applied to atomic hydrogen maps (H i) of galaxies can be used to quantify the effects of tidal interaction or star formation on the interstellar matter (ISM). Here we apply these parameters, concentration, asymmetry, smoothness, Gini, M20, and the GM parameter, to two public surveys of nearby dwarf galaxies, the Very Large Array-ANGST and Local Irregulars That Trace Luminosity Extremes-The H i Nearby Galaxy Survey, to explore whether tidal interaction or the ongoing or past star formation is a dominant force shaping the H i disc of these dwarfs. Previously, H i morphological criteria were identified for …

Mapping The Knowledge Economy Of Medicinal Plants In Northern Madagascar: Information And Resource Flow In Traditional Health Practices, Chanelle Adams

Independent Study Project (ISP) Collection

In the wake of pharmaceutical success with alkaloid compounds found in the Madagascar periwinkle (Catharanthus roseus), there has been increased attention towards identifying medicinal properties in the country’s rich flora. Both native and foreign companies seek profitable use of wild plant species found within Madagascar’s unique biodiversity. Many conservation organizations believe that the world’s forests in biological “hot spots” contain cures unknown to modern science and therefore, their preservation essential.

While the protection of these natural resources is important to Western medicine, it is even more vital for local people who depend on the forest as their primary …

Land Law, Land Rights, And Land Reform In Vietnam: A Deeper Look Into “Land Grabbing” For Public And Private Development, Kaitlin Hansen

Independent Study Project (ISP) Collection

As Vietnam continues to search for its ideal balance between Communist control and a market-led economy, land rights emerge at the forefront of the discussion concerning the tension between traditional Socialist ideals of people-owned and state managed property versus neoliberal ideals of private property rights. The purpose of this study is twofold. First, this study will explore the legal relationship between the Vietnamese state and individuals in regards to land ownership, land management, and land use rights, explaining how this relationship has changed over time with subsequent land laws. Going further, this study will focus on the 2013 land law …

Effects Of Ocean Acidification On The Behavior Of Two Marine Invertebrates: A Study Of Predator-Prey Responses Of The Molluscs Conus Marmoreus And Strombus Luhuanus At Elevated-Co2 Conditions, Jennifer Fields

Independent Study Project (ISP) Collection

Ocean acidification has been affecting the world’s oceans since the introduction of anthropogenic CO2 into the atmosphere during the Industrial Revolution. An increase in CO2 uptake from the atmosphere to the ocean has had a profound impact on not only the water chemistry, but marine organisms as well. Ocean acidification is known to have significant impacts on marine invertebrates in terms of calcification and reproduction; however, effects of increased CO2 on marine invertebrate behavior are vastly unknown. Marine conch gastropods have a modified muscularized foot that allows them to escape quite rapidly when faced with a predator cone shell. Utilizing …

Two Views On The Increasing Importance Of Library Access In The Seventeenth Century: Gabriel Naudé And Claude Clement, Erin M. Grant

Georgia Library Quarterly

Since their earliest days, libraries have struggled with meeting two opposing goals: preservation of materials and adequate user access to those same materials. Adequate user access to library materials includes physical access as well as providing a navigable system of organization that allows users to find needed materials. Although the privileging of access over preservation may seem like a modern concept, two seminal library treatises published a year apart in seventeenth-century France championed the issue of increased library access, especially by establishing usable organization in their respective collections: Gabriel Naudé’s Avis pour dresser une bibliothèque and Claude Clement’s Musei, sive …

Development Of Isotags For Nmr Based Metabolite Profiling And Applications, Fariba Tayyari

Open Access Dissertations

NMR spectroscopy is a powerful analytical tool for both qualitative and quantitative metabolite profiling analysis. However, accurate quantitative analysis of biological systems especially using one dimensional NMR has been challenging due to signal overlap. In contrast, the enhanced resolution and sensitivity offered by chemoselective isotope tags have enabled new and enhanced methods for detecting hundreds of quantifiable metabolites in biofluids using NMR spectroscopy or mass spectrometry. In this thesis we show improved sensitivity and resolution of NMR experiments imparted by 15N and 13C isotope tagging which enables the accurate analysis of plasma metabolites. To date, isotope tagging has been used …

Identification And Quantification Of Nonlinear Behavior In A Disbonded Aluminum Honeycomb Panel Using Single Degree-Of-Freedom Models, Eric Richard Dittman

Open Access Dissertations

There is not a complete understanding of how damage mechanisms in composite materials react to nondestructive testing inputs. A deeper understanding of composite damage mechanisms and their responses to external vibratory excitation is sought using nonlinear modeling of damping and stiffness characteristics related to the damage. Different types of damping and stiffness single degree-of-freedom models are presented with analysis of their behavior at specific harmonics of the primary resonance of the system. After an understanding of the approximate behaviors of the models is obtained, experimental tests on a damaged specimen are conducted. An aluminum honeycomb sandwich panel is damaged by …

What Munn Missed: The Queensland Schools Of Arts, Robin Wagner

All Musselman Library Staff Works

American Librarian Ralph Munn's historic tour of Australian libraries in 1934 is well documented. Along with Ernest Pitt, Chief Librarian of the State Library of Victoria, he spent nearly ten weeks travelling from Sydney and back again, visiting libraries in all the state capitals and many regional towns throughout the country. Munn's trip was funded by the Carnegie Corporation of New York, which was then, through its Dominions fund, turning attention to philanthropic opportunities in the Antipodes. The resulting report, Australian Libraries: A Survey of Conditions and Suggestions for their Improvement (commonly referred to as the Munn-Pitt Report) is often …

Human Economic Choice As Costly Information Processing, John Dickhaut, Vernon L. Smith, Baohua Xin, Aldo Rustichini

Accounting Faculty Articles and Research

We develop and test a model that provides a unified account of the neural processes underlying behavior in a classical economic choice task. The model describes in a stylized way brain processes engaged in evaluating information provided by the experimental stimuli, and produces a consistent account of several important features of the decision process in different environments: e.g., when the probability is specified or not (ambiguous choices). These features include the choices made, the time to decide, the error rate in choice, and the patterns of neural activation. The model predicts that the further two stimuli are from each other …

Higher Order Pwm For Modeling Transcription Factor Binding Sites, Dhivya Srinivasan

Master's Projects

Traditional Position Weight Matrices (PWMs) that are used to model Transcription Factor Binding Sites (TFBS) assume independence among different positions in the binding site. In reality, this may not necessarily be the case. A better way to model TFBS is to consider the distribution of dinucleotides or trinucleotides instead of just mononucleotides, thus taking neighboring nucleotides into account. We can therefore, extend the single nucleotide PWM to a dinucleotide PWM or an even higher-order PWM to correctly estimate the dependencies among the nucleotides in a given sequence. The purpose of this project is to develop an algorithm to implement higher-order …

Hidden Markov Models For Malware Classification, Chinmayee Annachhatre

Master's Projects

Malware is a software which is developed for malicious intent. Malware is a rapidly evolving threat to the computing community. Although many techniques for malware classification have been proposed, there is still the lack of a comprehensible and useful taxonomy to classify malware samples. Previous research has shown that hidden Markov model (HMM) analysis is useful for detecting certain types of malware. In this research, we consider the related problem of malware classification based on HMMs. We train HMMs for a variety of malware generators and a variety of compilers. More than 9000 malware samples are then scored against each …

Compression-Based Analysis Of Metamorphic Malware, Jared Lee

Master's Projects

Recent work has presented a technique based on structural entropy measurement as an effective way to detect metamorphic malware. The technique uses two steps, file segmentation and sequence comparison, to calculate file similarity. In another previous work, it was observed that similar malware have similar measures of Kolmogorov complexity. A proposed method of estimating Kolmogorov complexity was to calculate the compression ratio of a given malware which could then be used to cluster the malicious software. Malware detection has also been attempted through the use of adaptive data compression and showed promising results. In this paper, we attempt to combine …
