Wavefront Curvature Sensing From Image Projections, Jonathan C. Buffington

Theses and Dissertations

This research outlines the development and simulation of a signal processing approach to real time wavefront curvature sensing in adaptive optics. The signal processing approach combines vectorized Charge Coupled Device (CCD) read out with a wavefront modal estimation technique. The wavefront sensing algorithm analyzes vector projections of image intensity data to provide an estimate of the wavefront phase as a combination of several low order Zernike polynomial modes. This wavefront sensor design expands on an existing idea for vector based tilt sensing by providing the ability to compensate for additional modes. Under the proposed wavefront sensing approach, the physical wavefront …

Attachment Of Motile Bacterial Cells To Prealigned Holed Microarrays, Sergey Rozhok, Zhifang Fan, Dorjderem Nyamjav, Chang Liu, Chad A. Mirkin, Richard C. Holz

Chemistry Faculty Research and Publications

Construction of biomotors is an exciting area of scientific research that holds great promise for the development of new technologies with broad potential applications in areas such as the energy industry and medicine. Herein, we demonstrate the fabrication of prealigned microarrays of motile Escherichia coli bacterial cells on SiOx substrates. To prepare these arrays, holed surfaces with a gold layer on the bottom of the holes were utilized. The attachment of bacteria to the holes was achieved via nonspecific interactions using poly-l-lysine hydrobromide (PLL). Our data suggest that a single motile bacterial cell can be selectively attached to an individual …

The Coefficient Of Bohm Diffusion In Fully Ionized Plasma And Its Theoretical Proof, Ahmad Talaei, Reza Amrollahi

Graduate Student Presentations

As we know, the classical diffusion can not be able to respond the experimental results of the diffusion in the fully ionized and isothermal plasma. In this article, we purpose to extract the empirical coefficients of the Bohm diffusion and its confinement time, theoretically, in the fully ionized plasma, using the single fluid MHD equations.

Performance Comparison Of Hyperspectral Target Detection Algorithms, Adam Cisz

Theses

This thesis performs a performance comparison on existing hyperspectral target detection algorithms. The algorithms chosen for this analysis include multiple adaptive matched filters and the physics based modeling invariant technique. The adaptive matched filter algorithms can be divided into either structured (geometrical) or unstructured (statistical) algorithms. The difference between these two categories is in the manner in which the background is characterized. The target detection procedure includes multiple pre-processing steps that are examined here as well. The effects of atmospheric compensation, dimensionality reduction, background characterization, and target subspace creation are all analyzed in terms of target detection performance. At each …

Implementation Of Middle School Best Practice In A K-8 School: A Case Study Of The Planning Year For Barnette Magnet School In Fairbanks, Alaska, Colleen Smith-Thomas

Education

This study used a case study design to investigate the planning year for Barnette Magnet School, which opened in the fall of 2005. The conversion to a K-8 school is met with some difficulty by school districts across the nation because, while there are many benefits to keeping these 7th and 8th grade adolescents in their neighborhood elementary school where supportive relationships have already been developed, the fact remains that they have different social, emotional and academic needs than either elementary or high school students. This case study seeks to examine the current research into best educational practice for this …

Experimental And Numerical Fluid Flow Analysis Of An Intersecting Channel Flow-Field For Proton Exchange Membrane Fuel Cell Applications, Venkata A. Gudimetla

Engineering

The present work aims to analyze the geometry of a new flow-field plate called the intersecting channel flow-field, developed at the University of Alaska Fairbanks (UAF). Four different two-dimensional models have been investigated and analyzed for the uniform spatial mass flow distribution of air in the channels. Based on the outcome of the two-dimensional models, a three-dimensional model of the flow-field was analyzed using CFD and the results were compared with those from an experiment which was conducted at UAF. The results from the three-dimensional numerical analysis showed a minor deviation from the experimental results.

Change-Point Tests For Precipitation Data, Michael Robbins

All Theses

A new method is required for change-point testing of precipitation data that is capable of applying valid precipitation models. First, stochastic precipation models are researched and classified. Typically, the occurrence of rain is modeled using a two-state, first-order Markov chain, and the intensity of rain is modeled using a two-parameter gamma distribution. Using the likelihood ratio test statistic, methods are devoloped for testing for fixed and unknown change-points. These methods are developed for various models, including the MC/gamma model and simplified versions. The distribution of the LRT is unknown, however its asymptotic distribution is known for both the fixed and …

The Role Of Corticosterone And Corticosteroid-Binding Globulin In Reproduction Of Red-Legged Kittiwakes (Rissa Brevirostris), Thomas D. Dempsey

Biological Sciences

The goal of this study was to determine to what extent, and by what physiological and behavioral mechanisms, avian reproductive performance is related to environmental variability. Specifically, I explored relationships between components of the physiological stress response, reproductive behavior, and reproductive performance in the red-legged kittiwake (Rissa brevirostris), a long-lived seabird. I found that individuals respond to food-related stress by altering levels of both corticosteroid-binding globulin (CBG) and the primary avian glucocorticoid, corticosterone (Cort). I also found a negative association between breeding adults' Cort concentrations and population-level reproductive success; although no such association existed between CBG and reproductive success. The …

Patterns Of And Controls Over Nitrogen Inputs By Green Alder (Alnus Viridis Ssp. Fruticosa) To A Secondary Successional Chronosequence In Interior Alaska, Jennifer S. Mitchell

Biological Sciences

Patterns of and controls over N₂ fixation by green alder (A. viridis) were studied in post-fire, mid-succession, and white spruce upland forests in interior Alaska during 1997-2000, focusing on the hypothesis that ecosystem-level nitrogen (N) inputs decrease with successional development. Across all stands, alder created islands of elevated soil N and carbon, depleted soil phosphorus (P), and more acidic soils, effects which translated to the stand-level in response to greater alder stem density. Rates of N₂ fixation (measured by acetylene reduction = ARA) closely tracked plant phenology during the 1997 (a drought year) and 1998 (a year of normal precipitation) …

Micropulse Lidar Observations Of Aerosols Over The Atmospheric Radiation Measurement Site At Barrow, Ramaswamy A.S.R. Tiruchirapalli

Atmospheric Sciences

Micropulse lidar (MPL) is a ground-based optical remote sensing system designed to determine the vertical structure of clouds and aerosols in the atmosphere. An MPL has operated at Barrow, Alaska since November 2002. From these data, we seek to determine the altitude of aerosol layers in the free troposphere from lidar backscatter profiles. Layer heights are then fed into the HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory Model) model, a back-trajectory model developed by NOAA (National Oceanic and Atmospheric Administration) to compute isentropic back-trajectories. The model is run interactively using the READY interface and can calculate trajectories from multiple heights within …

Isostasy And Origin Of The Alpha-Mendeleev Ridge, Arctic Ocean, Christina C. Williams

Geosciences

The Alpha-Mendeleev Ridge is an aseismic ridge bisecting the Amerasian Basin, Arctic Ocean. There is no widely accepted theory of formation. Gravity and bathymetry data from the poorly understood ridge are used to constrain the isostatic compensation of the feature in the frequency domain. Spectral analysis of the cross correlation between gravity and bathymetry along nine data transects collected from submarines and ice breakers over the ridge yield an average crustal thickness estimate of 30 km and density estimate of 2.75 g-cm⁻³. It also suggests compensation by local isostasy, as a near-ridge oceanic plateau or an extended fragment of continental …

Screencrayons: Using Screen Captures For Annotation And Research, Trent Alan Taufer

Theses and Dissertations

In a world full of digital information we should be able to easily collect, organize, annotate, and leverage information from many different sources. This should be easy to do and not interrupt our normal workflow. A system to support information collection and organization should be user-friendly and as unobtrusive as possible, while still allowing for flexible and intelligent annotation. It should also be able to leverage the inherent information content of a collection of annotated information. We present a system that will demonstrate how these ideas can come together to make information collection easier and more productive. The system facilitates …
