New Exact Solutions Of Some Nonlinear Partial Differential Equations By The First Integral Method, Nasir Taghizadeh, Mohammad Mirzazadeh, Foroozan Farahrooz
Applications and Applied Mathematics: An International Journal (AAM)
The first integral method is an efficient method for obtaining exact solutions of nonlinear partial differential equations. The efficiency of the method is demonstrated by applying it for two selected equations. This method can be applied to nonintegrable equations as well as to integrable ones.
Numerical Comparison Of Methods For Hirota-Satsuma Model, Syed T. Mohyud-Din, Ahmet Yildirim, Syed M. Mahdi Hosseini
Numerical Comparison Of Methods For Hirota-Satsuma Model, Syed T. Mohyud-Din, Ahmet Yildirim, Syed M. Mahdi Hosseini
Applications and Applied Mathematics: An International Journal (AAM)
This paper outlines the implementation of the modified decomposition method (MDM) to solve a very important physical model namely Hirota-Satsuma model which occurs quite often in applied sciences. Numerical results and comparisons with homotopy perturbation (HPM) and Adomian’s decomposition (ADM) methods explicitly reveal the complete reliability of the proposed MDM. It is observed that the suggested algorithm (MDM) is more user-friendly and is easier to implement compared to HPM and ADM.
Heavy Metal Concentrations In Water And Surface Sediments Of Wilgreen Lake, Madison County, Kentucky, Chad Von Gruenigen, Walter S. Borowski
Heavy Metal Concentrations In Water And Surface Sediments Of Wilgreen Lake, Madison County, Kentucky, Chad Von Gruenigen, Walter S. Borowski
EKU Faculty and Staff Scholarship
Heavy metal pollution remains problematic in natural waters, particularly for localities near plausible anthropogenic sources. We assayed the level of heavy metals in surface waters and within surface sediments of Wilgreen Lake, whose watershed drains industrial, urban, agricultural, and residential areas near Richmond, Kentucky. Water samples were treated according to Environmental Protection Agency (EPA) protocols and digested with trace-metal-grade nitric and hydrochloric acids. Sediment samples were collected with a grab sampler and digested using established EPA procedures with hydrogen peroxide and trace-metal-grade nitric acid. Both water samples and sediment samples were sent to Activation Laboratories for analysis, and were measured …
Model-Based Analysis Of Electric Drive Options For Medium-Duty Parcel Delivery Vehicles, Robb A. Barnitt, Aaron D. Brooker, Laurie Ramroth
Model-Based Analysis Of Electric Drive Options For Medium-Duty Parcel Delivery Vehicles, Robb A. Barnitt, Aaron D. Brooker, Laurie Ramroth
Publications (T)
Medium-duty vehicles are used in a broad array of fleet applications, including parcel delivery. These vehicles are excellent candidates for electric drive applications due to their transient-intensive duty cycles, operation in densely populated areas, and relatively high fuel consumption and emissions. The National Renewable Energy Laboratory (NREL) conducted a robust assessment of parcel delivery routes and completed a model-based techno-economic analysis of hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) configurations. First, NREL characterized parcel delivery vehicle usage patterns, most notably daily distance driven and drive-cycle intensity. Second, drive-cycle analysis results framed the selection of drive cycles used …

Iota-Carrageenan Hydrolysis By Pseudoalteromonas Carrageenovora Ifo12985, Bernadette M. Henares, Erwin P. Enriquez, Fabian M. Dayrit, Nina Rosario L. Rojas
Iota-Carrageenan Hydrolysis By Pseudoalteromonas Carrageenovora Ifo12985, Bernadette M. Henares, Erwin P. Enriquez, Fabian M. Dayrit, Nina Rosario L. Rojas
Chemistry Faculty Publications
We report iota-carrageenan hydrolysis by Pseudoalteromonas carrageenovora IFO 12985. Kappa-carrageenase and lambda-carrageenase were previously isolated from this organism, but iota-carrageenase activity had not been reported in the literature. P. carrageenovora was grown in iota-carrageenan-based liquid medium. Using the zone of depression assay, transfer of aliquots of the culture to solid medium with 2% iota- and kappa-carrageenan showed extensive hydrolysis of iota-carrageenan. Analysis of the hydrolysates by C-13 Nuclear Magnetic Resonance spectroscopy confirmed degradation of the iota-carrageenan. Hydrolytic activity of P. carrageenovora grown in iota-carrageenan was compared with that of the same organism grown in kappa-carrageenan. Cell-free supernatants from each yielded …

Late Quaternary Slip Rate On The Kern Canyon Fault At Soda Spring, Tulare County, California, Colin B. Amos, Keith I. Kelson, Dylan H. Rood, David T. Simpson, Ronn S. Rose
Geology Faculty Publications
The Kern Canyon fault represents a major tectonic and physiographic boundary in the southern Sierra Nevada of east-central California. Previous investigations of the Kern Canyon fault underscore its importance as a Late Cretaceous and Neogene shear zone in the tectonic development of the southern Sierra Nevada. Study of the late Quaternary history of activity, however, has been confounded by the remote nature of the Kern Canyon fault and deep along-strike exhumation within the northern Kern River drainage, driven by focused fluvial and glacial erosion. Recent acquisition of airborne lidar (light detection and ranging) topography along the ∼140 km length of …
The Cohomology Of Modules Over A Complete Intersection Ring, Jesse Burke
The Cohomology Of Modules Over A Complete Intersection Ring, Jesse Burke
Department of Mathematics: Dissertations, Theses, and Student Research
We investigate the cohomology of modules over commutative complete intersection rings. The first main result is that if M is an arbitrary module over a complete intersection ring R, and if one even self-extension module of M vanishes then M has finite projective dimension. The second main result gives a new proof of the fact that the support variety of a Cohen-Macaulay module whose completion is indecomposable is projectively connected.

Cropland Nesting By Long-Billed Curlews In Southern Alberta, James H. Devries, Steven O. Rimer, Elizabeth M. Walsh
Cropland Nesting By Long-Billed Curlews In Southern Alberta, James H. Devries, Steven O. Rimer, Elizabeth M. Walsh
The Prairie Naturalist
Long-billed curlews (Numenius americanus) are described primarily as a grassland nesting species. However, no studies to date have quantified nest habitat selection among available habitats. During a study of waterfowl nest habitat selection and success in landscapes ranging from cropland to grassland-dominated, we found 9 curlew nests of which 8 were located in active cropland within cropland-dominated landscapes. Cropland nests occurred in fall-seeded winter wheat and spring-seeded barley and nests were clumped in distribution. Four cropland nests and 1 nest in native grass pasture hatched young. Further research is needed to characterize nesting habitat selection and reproductive success …
Examination Of Owl Pellets For Northern Pocket Gophers At Crescent Lake National Wildlife Refuge, Nebraska, Stacey L. Bonner, Keith Geluso
Examination Of Owl Pellets For Northern Pocket Gophers At Crescent Lake National Wildlife Refuge, Nebraska, Stacey L. Bonner, Keith Geluso
The Prairie Naturalist
Analysis of regurgitated pellets from owls is a well-known and nondestructive method that provides useful information regarding diet (Errington 1930). This technique also is used to examine composition of small mammal communities and distribution of prey species (e.g. Kamler et al. 2003, Torre et al. 2004, Poole and Matlack 2007). In western Nebraska, two species of owls that regularly breed in the region are the common barn owl (Tyto alba) and great horned owl (Bubo virginianus). In the early 1970s, Rickart (1972) studied the diet of both species at Crescent Lake National Wildlife Refuge (CLNWR), Garden …

The Prairie Naturalist
Habitat use of sympatric greater prairie-chicken (Tympanuchus cupido) and sharp-tailed grouse (T. phasianellus) broods during the brood-rearing season has not been quantified for stable prairie grouse populations in large contiguous grassland landscapes in the Northern Great Plains. Characteristics of habitats used by prairie grouse broods were described based on data collected from 35 broods (18 greater prairie-chicken and 17 sharp-tailed grottse) during the breeding seasons of 2004 and 2005. Greater prairie-chicken and sharp-tailed grouse broods used vegetation with visual obstruction heights 2:26 cm and 37 cm, respectively. Greater prairie-chicken broods selected western wheatgrass (Pascopyrum smithii …

Electrochemical Investigation Of Azurin Thermodynamic And Adsorption Properties At Monolayer-Protected Cluster Film Assemblies – Evidence For A More Homogeneous Adsorption Interface, Tran Doan, Morgan Lynn Vargo, John K. Gerig, Chris P. Gulka, Matthew L. Trawick, Jonathan D. Dattelbaum, Michael C. Leopold
Chemistry Faculty Publications
Thermodynamic and adsorption properties of protein monolayer electrochemistry (PME) are examined for Pseudomonas aeruginosa azurin (AZ) immobilized at an electrode modified with a networked film of monolayer-protected clusters (MPCs) to assess if nanoparticle films of this nature offer a more homogeneous adsorption interface compared to traditional self-assembled monolayer (SAM) modified electrodes. Specifically, electrochemistry is used to assess properties of surface coverage, formal potential, peak broadening, and electron transfer (ET) kinetics as a function of film thickness. The modification of a surface with dithiol-linked films of MPCs (Au225C675) provides a more uniform binding interface for AZ that results in voltammetry with …

A Study Of African American Forest Landowners In South Carolina: Implications For Land Ethic And Forest Stewardship, Keenan Adams
A Study Of African American Forest Landowners In South Carolina: Implications For Land Ethic And Forest Stewardship, Keenan Adams
All Dissertations
African Americans account for a significant proportion of South Carolina`s
population but reportedly own a disproportionally smaller amount of land. Research indicates that landowners who hold significant sources of sustainable wealth and power can dramatically increase their quality of life and ultimately that of their communities. Current land loss trends for African Americans are increasing at an alarming rate, which may have larger social implications for this traditionally underserved population. The remaining African American landowners are a rapidly declining group, due to an assortment of factors (e.g., age, heirs property). Understanding the experiences of the residual African American forest landowners …
In Silico Modeling Of Ph-Optimum Of Protein-Protein Binding, Rooplekha C. Mitra, Zhe Zhang, Emil Alexov
In Silico Modeling Of Ph-Optimum Of Protein-Protein Binding, Rooplekha C. Mitra, Zhe Zhang, Emil Alexov
Publications
Protein-protein association is a pH-dependent process and thus the binding affinity depends on the local pH. In vivo the association occurs in a particular cellular compartment, where the individual monomers are supposed to meet and form a complex. Since the monomers and the complex exist in the same micro environment, it is plausible that they coevolved toward its properties, in particular, toward the characteristic subcellular pH. Here we show that the pH at which the monomers are most stable (pH-optimum) or the pH at which stability is almost pH-independent (pH-flat) of monomers are correlated with the pH-optimum of maximal affinity …

Large Group Delay In A Microwave Metamaterial Analog Of Electromagnetically Induced Transparency, Lei Zhang, Philippe Tassin, Thomas Koschny, Cihan Kurter, Steven M. Anlage, C. M. Soukoulis
Physics Faculty Research & Creative Works
We report on our experimental work concerning a planar metamaterial exhibiting classical electromagnetically induced transparency (EIT). Using a structure with two mirrored split-ring resonators as the dark element and a cut wire as the radiative element, we demonstrate that an EIT-like resonance can be achieved without breaking the symmetry of the structure. The mirror symmetry of the metamaterial's structural element results in a selection rule inhibiting magnetic dipole radiation for the dark element, and the increased quality factor leads to low absorption (<10%) and large group index (of the order of 30).
The Removal Of Wood Components From Hardwood By Hot Water, Rory Jara
The Removal Of Wood Components From Hardwood By Hot Water, Rory Jara
Electronic Theses and Dissertations
Hot-water extraction of hemicelluloses from wood is a promising technology in the integrated biorefmery concept. A particular case is where the pulp industry makes co-products such as ethanol and acetic acid besides pulp thereby maximizing the value of biomass. Similarly, the oriented strand board (OSB) industry appears to be suitable for this technical approach as it is composed of large centralized facilities. Many studies have been carried out on the kinetics and mechanism of hot-water extraction of lignocellulosics. However, most of these studies were performed in batch reactors which are not best suited to determine intrinsic kinetics of hemicellulose dissolution …

Scattering Matrix Elements For The Nonadiabatic Collision B (2PJₐ) + H2 (1Σ+G, Ν, Ј) ↔ B (2PJ’ₐ) + H2 (1Σ+G, Ν’, J’), Luke A. Barger
Theses and Dissertations
Scattering matrix elements are calculated for the nonadiabatic inelastic collision B (2Pjₐ) + H2 (1Σ+g, ν, ј) ↔ B (2Pj’ₐ) + H2 (1Σ+g, ν’, j’). This calculation utilizes the effective potential energy surfaces for this collision generated by Garvin along with a correction to the asymptotic H2 potential. Wavepackets are propagated on these surfaces using a split-operator propagator. This propagation yields correlation functions between reactant and product Møller states which are used to calculate the scattering …

Closed-Range Composition Operators On A2 And The Bloch Space, John R. Akeroyd, Pratibha G. Ghatage, Maria Tjani
Mathematics and Statistics Faculty Publications
For any analytic self-map φ of {z : |z| < 1} we give four separate conditions, each of which is necessary and sufficient for the composition operator Cφ to be closed-range on the Bloch space B . Among these conditions are some that appear in the literature, where we provide new proofs. We further show that if Cφ is closed-range on the Bergman space A2 , then it is closed-range on B , but that the converse of this fails with a vengeance. Our analysis involves an extension of the Julia-Carathéodory Theorem.
The Gini Index And Measures Of Inequality, Frank A. Farris
The Gini Index And Measures Of Inequality, Frank A. Farris
Mathematics and Computer Science
The Gini index is a summary statistic that measures how fairly a resource is distributed in a population; income is a primary example. In addition to a self-contained presentation of the Gini index, we give two equivalent ways to interpret this summary statistic: first in terms of the percentile level of the person who earns the average dollar, and second in terms of how the lower of two randomly chosen incomes compares, on average, to mean income.

Analysis Of False Cache Line Sharing Effects On Multicore Cpus, Suntorn Sae-Eung
Analysis Of False Cache Line Sharing Effects On Multicore Cpus, Suntorn Sae-Eung
Master's Projects
False sharing (FS) is a well-known problem occurring in multiprocessor systems. It results in performance degradation on multi-threaded programs running on multiprocessor environments.
With the evolution of processor architecture over time, the multicore processor is a recent direction used by hardware designers to increase performance while avoiding heat and power walls. To fully exploit the processing power from these multicore hardware architectures, the software programmer needs to build applications using parallel programming concepts, which are based upon multi-threaded programming principles.
Since the architecture of a multicore processor is very similar to a multiprocessor system, the presence of the false sharing …

Effect Of Network Structure On The Stability Margin Of Large Vehicle With Distributed Control, He Hao, Prabir Barooah, J. J. P. Veerman
Mathematics and Statistics Faculty Publications and Presentations
We study the problem of distributed control of a large network of double-integrator agents to maintain a rigid formation. A few lead vehicles are given information on the desired trajectory of the formation; while every other vehicle uses linear controller which only depends on relative position and velocity from a few other vehicles, which are called its neighbors. A predetermined information graph defines the neighbor relationships. We limit our attention to information graphs that are D-dimensional lattices, and examine the stability margin of the closed loop, which is measured by the real part of the least stable eigenvalue of …

The lack of adequate field measurements (e.g., precipitation and stream flow) and difficulty in obtaining them often hampers the construction and calibration of rainfall-runoff models over many of the world's watersheds, leaving key· elements of the hydrologic cycle unconstrained. I adopted methodologies that rely heavily on readily available remote sensing datasets as viable alternatives and useful tools for assessing, managing, and modeling the water resources of such remote and inadequately gauged regions.
The Soil and Water Assessment Tool was selected for continuous (1998-2005) rainfall-runoff modeling of the northeast part of the Pishin Lora basin (NEPL), a politically unstable area that …

Parallel Unmixing Of Hyperspectral Data Using Complexity Pursuit, Stefan Robila, Martin Butler
Parallel Unmixing Of Hyperspectral Data Using Complexity Pursuit, Stefan Robila, Martin Butler
Department of Computer Science Faculty Scholarship and Creative Works
Accurate and fast data unmixing is key to most applications employing hyperspectral data. Among the large number unmixing approaches, Blind Source Separation (BSS) has been employed successfully through a variety of techniques, yet most of these approaches continue to be computationally expensive due to their iterative nature. In this context, it is imperative to seek efficient approaches that leverage the accuracy of the algorithms and the availability of off-the-shelf computationally performant systems such as multi-cpu and multi core. In this paper we tackle the spatial complexity based unmixing, a new technique shown to outperform many BSS solutions. We develop a …

Considerations On Unsupervised Spectral Data Unmixing And Complexity Pursuit, Stefan Robila
Department of Computer Science Faculty Scholarship and Creative Works
Hyperspectral sensors carry the distinctive advantage of recording hundreds of contiguous spectral images for the same scene providing an extraordinary amount of information that leads to precise differentiation of materials present in the scene even when such materials contribute only to few pixels [1]. With the advent of more and more powerful sensing platforms, coupled with reduction in manufacturing costs and diversification of technologies, hyperspectral imaging has become a powerful approach in remote sensing with applications spanning all traditional fields (such as agriculture, mining, military, resource management, etc.) as well as new ones (manufacturing quality control, pollution detection, health and …
