Minimal Nodal Domains For Strictly Elliptic Partial Differential Equations With Homogeneous Boundary Conditions, Charles E. Miller May 2006

Minimal Nodal Domains For Strictly Elliptic Partial Differential Equations With Homogeneous Boundary Conditions, Charles E. Miller

All Graduate Theses and Dissertations

This work presents a proof of the dependence of the first eigenvalue for uniformly elliptic partial differential equations on the domain in a less abstract setting than that of Ivo Babushka and Rudolf Vyborny in 1965. The proof contained here, under rather mild conditions on the boundary of the domain, �Ω, demonstrates that the first eigenvalue of elliptic partial differential equation

[ �� + �� = 0 �� Ω

[ � = 0 �� �Ω

depends continuously on the domain in the following sense. If a sequence of domains is such that, then the corresponding first eigenvalues satisfy is the first eigenvalue for

[ �� + �� = 0 �� Ω

[ � = 0 �� �Ω

The Evolution From Late Miocene West Salton Detachment Faulting To Cross-Cutting Pleistocene Oblique Strike-Slip Faults In The Sw Salton Trough, Southern California, Alexander N. Steely May 2006

The Evolution From Late Miocene West Salton Detachment Faulting To Cross-Cutting Pleistocene Oblique Strike-Slip Faults In The Sw Salton Trough, Southern California, Alexander N. Steely

All Graduate Theses and Dissertations

Field studies in the southwest Salton Trough between Yaqui Ridge and Borrego Mountain show that the West Salton detachment fault was active during the Pliocene and may have initiated during the latest Miocene. At Yaqui Ridge dominantly east-directed extension is recorded by slickenlines on the NW-striking detachment fault, and shows that the fault is actually a low-angle dextral oblique strike-slip fault. Crustal inheritance is responsible for the position of the fault at Yaqui Ridge, which reactivates a late Cretaceous reverse -sense mylonite zone at map scale. Late Miocene to Pliocene basin fill deposits at Borrego Mountain display progressive unconformities, contain ...


Wavelet Techniques In Time Series Analysis With An Application To Space Physics, Agnieszka Jach May 2006

Wavelet Techniques In Time Series Analysis With An Application To Space Physics, Agnieszka Jach

All Graduate Theses and Dissertations

Several wavelet techniques in the analysis of time series are developed and applied to real data sets.

Methods for long-memory models include wavelet-based confidence intervals for the self-similarity para meter in potentially heavy-tailed observations. Empirical coverage probabilities are used to assess the procedures by applying them to Linear Fractional Stable Motion with many choices of para meters. Asymptotic confidence intervals provide empirical coverage often much lower than nominal and it is recommended to use subsampling confidence intervals. A procedure for monitoring the constancy of the self-similarity parameter is proposed and applied to Ethernet data sets.

A test to distinguish a ...

Fundamentals Of Mountain Resort Base Village Design: A Critical Review Of Existing Resort Developments With Recommendations For Future Development Practices, Bryan P. Harding

All Graduate Theses and Dissertations

The North American ski industry has grown over the past century from a small, family-owned and -operated industry, to a multi-billion dollar industry dominated by corporate management organizations. The rise of corporate resort ownership has led to the trend of the construction base village developments at ski resorts around the country to attract guests, and therefore revenue, to their resorts. Though many base villages have been very successful in attracting skiers, examples of poor landscape architectural design practices abound in the industry. This study examines several design elements considered to be the "fundamental elements of designed space," applies these elements ...


New Perspectives On The Relationship Between Emotion Decoding And Social Acceptance In School-Age Children, Eri Suzuki May 2006

New Perspectives On The Relationship Between Emotion Decoding And Social Acceptance In School-Age Children, Eri Suzuki

All Graduate Theses and Dissertations

The relationship between children's emotion decoding ability and their social acceptance was examined, with a major focus on potential nonlinear components. Based on the display rules literature, the prediction was tested that social acceptance and emotion decoding skills can be best described as an inverted U-shaped function. Children in kindergarten through fifth grade (113 girls and 123 boys) completed measures of postural and facial decoding accuracy (FACES and TALK) and their social acceptance was assessed using child and teacher reports (SPPC or PSPC). The results showed only a statistically significant quadratic relationship for girls and a statistically significant linear ...

Environmental, Chemical, And Genetic Reduction Of Ethylene Sensitivity In Crop Plants, Timothy J. Hudelson May 2006

Environmental, Chemical, And Genetic Reduction Of Ethylene Sensitivity In Crop Plants, Timothy J. Hudelson

All Graduate Theses and Dissertations

Ethylene is an endogenously synthesized plant hormone that dissipates quickly in field conditions and seldom exceeds five nmol mol-1. Ethylene can accumulate to 1000 times this level in closed environments. The best-known effects of ethylene are its impacts on fruit ripening and senescence, yet ethylene influences growth and development throughout the plant life cycle. At low, continuous concentrations (20 to 50 nmol mol-1), ethylene reduces yield of many plants. Clean-air treatment during critical stages of floral development, silver thiosulfate (STS), and 1-methylcyclopropene (1- MCP) may delay flower senescence and reduce the detrimental effects of ethylene on peas and tomatoes grown ...


Model-Centered Instruction: A Design Research Study To Investigate An Alternative Approach To Patient Education, Mary Ann Parlin May 2006

Model-Centered Instruction: A Design Research Study To Investigate An Alternative Approach To Patient Education, Mary Ann Parlin

All Graduate Theses and Dissertations

While medical technology, intervention, and treatment continue to advance, patients often find themselves involved in an increasingly complex healthcare system . Because of this, many patients lack access to the knowledge to facilitate successful navigation or participation in healthcare systems to their best advantage. Patient Ill education that provides experiential information has been shown to reduce anxiety levels and increase patient health outcomes and compliance with medical instructions or recommendations. Given the demonstrated effectiveness of experiential instruction in patient education, Model-Centered Instruction (MCI) has the potential to be an effective instructional design for patient education because it affords the learner experience ...

Secondary Electron Production And Transport Mechanisms By Measurement Of Angle-Energy Resolved Cross Sections Of Secondary And Backscattered Electron Emission From Gold, Jason T. Kite May 2006

Secondary Electron Production And Transport Mechanisms By Measurement Of Angle-Energy Resolved Cross Sections Of Secondary And Backscattered Electron Emission From Gold, Jason T. Kite

All Graduate Theses and Dissertations

This work provides information about interactions that produce emitted electrons from polycrystalline Au. Emission energy- angle- dependent electron spectra from a polycrystalline Au surface have been measured at several incident electron beam energies. The range of incident energies (~100 eV to 2500 eV) extends from below the first crossover energy, through Emaxo, to above the second crossover energy. The conventional distinction between secondary electrons (SE) (50 eV) is found to be crude for the investigation of electron yields using these energy- angle- resolved measurements. A more realistic boundary occurs at the local minima of the emission spectra; this ...


Historical Biogeography Of North American Nightsnakes And Their Relationships Among The Dipsadines: Evidence For Vicariance Associated With Miocene Formations Of Northwestern Mexico, Daniel G. Mulcahy May 2006

Historical Biogeography Of North American Nightsnakes And Their Relationships Among The Dipsadines: Evidence For Vicariance Associated With Miocene Formations Of Northwestern Mexico, Daniel G. Mulcahy

All Graduate Theses and Dissertations

I used a Hierarchical approach to study historical biogeography in a group of colubrid snakes found in western North America. I combined small regions of mtDNA sequence data from a large number of individuals, with complete mt-genomic data. First, I investigated the relationships among leptodeirines-a presumed subgroup of dipsadines includeng nightsnakes (Pseudoleptodeira, Eridiphas, and Hypsiglena) - using ~1.5 Kb of data (cob and nad4). The relationships differed among parsimony, likelihood, and bayesian analyses. All analyses supported the monophyly of the nightsnakes; however, none supported the monophyly of the leptodeirines. Instead, these data supported a new hypothesis that the dipsadines were ...
