The Hyperboloid Model Of Hyperbolic Geometry, Zachery S. Lane Solheim

EWU Masters Thesis Collection

"The main goal of this thesis is to introduce and develop the hyperboloid model of Hyperbolic Geometry. In order to do that, some time is spent on Neutral Geometry as well as Euclidean Geometry; these are used to build several models of Hyperbolic Geometry. At this point the hyperboloid model is introduced, related to the other models visited, and developed using some concepts from physics as aids. After the development of the hyperboloid model, Fuchsian groups are briefly discussed and the more familiar models of Hyperbolic Geometry are further investigated"--Document.

Optimization Of Conditions For Vitrification Of Aqueous Solutions Of Relevance To Cryobiology, Michael J. Baker

EWU Masters Thesis Collection

"Cryopreservation is a technology with wide ranging applications including helping to prevent specis extinction (Hopkins and Herr, 2010). However, the current applicability of cryopreservation protocols is limited. This limitation warranted experimentation that could contribute to the optimization of current protocols for cryopreservation. The experiments presented herein were designed to contribute to the plunge-cooling method of cryopreservation. The importance for further development of current plunge-cooling methods is for the cryopreservation of cell-types sensitive to the other method of cryopreservation, slow-equilibrium freezing. The purpose for plunge-cooling is to cool a sample from ambient temperature to liquid nitrogen temperature at a fast rate. …

Reassessing The Cultural Distance Between China And The United States As Perceived By Students From The Sino-American 1+2+1 Dual Degree Program, Cynthia Letts

EWU Masters Thesis Collection

"As a result of the exponential growth of international commerce and academic exchange between Mainland China and the United States, this thesis examines the present-day validity of those Chinese and American cultural characteristics, such as practices and values, historically understood as defining cultural differences. Using Babiker's Cultural Distance Index (Babiker, Cox, & Miller, 1980) questionnaire (an institutionally established instrument since 1980), 45 Mainland Chinese student-sojourners conveyed their perceptions of cultural differences found in daily living. Chinese participants identified many cultural attributes that still affect the migrant's perceptions of difference. These attributes are language, food, education costs, and leisure activities. Participants …

Improvisation: Narrative And Character Techniques In Jazz Pedagogy, Nathan Geyer

EWU Masters Thesis Collection

"This paper explores techniques in theatrical improvisation and discovers how they can be applied to jazz improvisation pedagogy. Improvised character and narrative are addressed from a theatrical standpoint and techniques are demonstrated to be easily relatable to jazz. The author proposes some techniques for use by educators of jazz improvisation and gives examples of how to teach simple concepts to ensembles using theatrical methods. It is the intent that these concepts will help develop soloists who perform jazz solos from a storytelling standpoint. The paper favors the use of impersonation rather than imitation of jazz artists, and also reincorporation rather …

Effects Of Predator Urine On Deterring Ungulate Browsing Of Aspen On The Turnbull National Wildlife Refuge, Savanah Walker

EWU Masters Thesis Collection

"In the Pacific Northwest, quaking aspen (Populus tremuloides) support large amounts of biodiversity and are considered second only to riparian zones. Due to aspen's ecological importance and recent decline on Turnbull National Wildlife Refuge (TNWR), increasing aspen regeneration is of high priority. The elk (Cervus elaphus) population on TNWR has greatly increased over the last decade and over browsing is attributed as a factor affecting aspen regeneration. In response to the decline of aspen regeneration, TNWR initiated an elk hunt in 2010 to cull and disperse elk. However, hunting is not a viable solution in public use areas of the …

Lepeophtheirus Salmonis, Parasitizing Three Species Of Pacific Salmon (Oncorhynchus Spp.): Host Variations In Load, Morphology, Fecundity, And Genetics Of The Salmon Louse, Stephen Flanagan

EWU Masters Thesis Collection

"The purpose of this study is to determine biological parameters of salmon lice (Lepeophtheirus salmonis) as they parasitize different species of Pacific Ocean salmonids off the north Pacific coast of Washington State. Parasite load counts of L. salmonis were made and individuals were collected from salmonids in their natural environment. Louse morphology and fecundity were examined using microscopy. Parasite loads were equal between different species of salmonids (p = 0.231). Lice that infected chinook salmon (n= 48) were smaller in total body length (p < 0.001), cephalothorax length (p < 0.001), and cephalothorax width (p < 0.001) when compared to lice that infected coho salmon (n = 44) or pink salmon (n=45). Lice that infected coho and pink salmon were not statistically different in body length (p = 0.213), cephalothorax length (p = 0.996), or cephalothorax width (p = 0.149). Also, L. salmonis produced fewer eggs when infecting chinook salmon (n = 24) than when infecting coho salmon (p < 0.001) or pink salmon (p < 0.001). Whereas, lice that infected coho salmon (n = 41) or pink salmon (n = 22) produced similar number of eggs (p = 0.60). These results indicate that there are factors associated with infecting chinook salmon hosts that reduce the size and fecundity of salmon lice"--Document.

Elk Hunting On Turnbull National Wildlife Refuge: Impacts On Elk Movement And Aspen Regeneration, Christopher E. Dwight

EWU Masters Thesis Collection

"In the arid West, quaking aspen (Populus tremuloides) cover less than 10% of the forest landscape, yet support a disproportionate diversity of native plants and animals. When elk (Cervus elaphus) become overabundant, browsing prevents aspen regeneration, reduces survival, and consequently impacts local biodiversity. Given this, Turnbull National Wildlife Refuge (TNWR) initiated a limited annual elk hunt beginning in fall 2010. This study examines whether the hunt affected elk usage of the refuge and, indirectly, aspen growth and regeneration. To determine elk movement and usage of the refuge prior to and following the elk hunt, 34 radio-collared cow elk were monitored …

Energy Efficiency In Wastewater Treatment: Standards For Missouri Facilities, Samantha Lauren Markus

Masters Theses

"Traditionally, energy has been used to treat wastewater. As energy costs rise, so does the financial burden on communities with municipal wastewater treatment plants (WWTP). Determining energy efficiency of small to mid-sized plants is difficult because these plants are the least likely to have the resources to conduct an energy audit and the most likely to be overlooked in national models due to their small contribution to the national energy burden. Data was gathered via personal contact the WWTPs in Missouri and from this data metrics fro comparison were developed. The data was also compared to the predicted energy use …

Implementation And Evaluation Of Spatial Audio Recording And Rendering Techniques, Jayasecha Raghavendra Nimmala

Masters Theses

"The thesis is divided into two main sections. First half describes the implementation of different adaptive beamforming techniques. Adaptive beamforming techniques are widely used in many real world applications like teleconferencing, speech recognition, devices for the hearing impaired, radar, sonar, etc. The beamformer is an array of sensors which can be electronically steered to any particular direction to enhance the signal in the direction of interest while at the same time suppressing interference or jammers coming from other directions.

In our experiment, we implement both the regularized minimum variance distortionless receiver (MVDR) and the generalized sidelobe canceller (GSC). The beamforming …

Wavelet Based Contrast Limited Histogram Equalization For Contrast Enhancement Of Digital Mammography, Ashish Vighnahar Avachat

Masters Theses

"Mammography has been the most efficient tool for screening of microcalcification and cancer tissues; however, the raw images produced by mammography systems are usually of poor contrast. In order to use these raw images for early diagnosis; their contrast, sharpness and noise need to be enhanced. Among these important enhancement parameters contrast enhancement is critical. A novel algorithm is introduced which blends wavelet transforms with Contrast Limited Adaptive Histogram Equalization (CLAHE) for contrast enhancement. In this algorithm, the input image is decomposed to its low frequency and high frequency components in wavelet domain. Decomposed coefficients from different bands are then …

A Three-Dimensional Transient Simulation Of An Electrochemical Magnetohydrodynamics Cell With Micro And Millielectrode: A Unified Reconciliation Of Theory And Experiment, Cajon Gonzales

Masters Theses

"Even though electrochemically induced magnetohydrodynamic (MHD) convection is a straightforward inexpensive method for moving fluids in confined spaces as for example during electrodeposition, stripping voltammetry, or in microfluidics, efficient quantitative models only recently have begun to appear. This is traced to complex mathematics that have prevented development of analytical expressions, e.g., for mass-transfer limited currents in analogy to the well-known Levich equation for the rotating electrode. Thus, related literature expressions remain mainly phenomenological concerning particular cell geometries or applications. Here, using such reports as points of departure, we validate a computationally rigorous description of the magnetoelectrochemical problem and define the …
