Ellipses of Gravel
<p>This manuscript was my attempt to create a collection of poetry that could potentially be published as a book. I wrote and revised poetry in accordance with lessons learned from several of the authors I studied at Eastern Kentucky University. Workshop courses offered valuable feedback from …

Particle Ellipses in Japanese
In this study I consider two kinds of particle ellipsis, syntactic particle ellipsis and conversational particle ellipsis. Syntactic particle ellipsis (discussed in Chapter 1) is the type of particle ellipsis caused by certain syntactic conditions. Only case particles are ellipted under these …

Confidence Ellipses Under the Inverse Gaussian Distribution
… how it applies to the construction of con dence ellipses of parameters associated with the Inverse Gaussian Distribution. This thesis consists of two parts, the rst part being the theoretical with where we seek to operate a classical estimation method known as the maximum likelihood. This is …

Extension of the Method of Ellipses to Determining the Orientation of Long, Semi-flexible Fibers in Model 2- and 3-dimensional Geometries
… the application and validity of the Method of Ellipses for determining the orientation of long, semi-flexible glass fibers within injection molded composites has been investigated. A fiber suspension with an average length of approximately 3.9 mm was the focus of this study and assumed to be …

Characterizing Hydrodynamic Interactions of Underwater Vehicles in Close Proximity Using an Identical Ellipse Pair
… interactions between two identical 6:1 ellipses in close proximity were investigated using a 2D immersed interface method simulator in a viscous, rotational flow at Re=1500. Interactions in tandem, side-by-side, and staggered arrangements were characterized based on changes to the drag, …

Computational Aspects of An Asymptotic Analysis of Method of Moments Estimators of Parameters For the Binomial Distribution
… These formulae allow us to draw confidence ellipses for the parameters. For the 100(1-α)% confidence region, we consider the ellipses: {(p,m)|Z ̂_2^2 (p,m)≤χ_2^2 (α)} and {(p,m)|Z ̃_2^2 (p,m)≤χ_2^2 (α)}, where χ^2 (α) is the percentile of chi-square distribution with two degrees of freedom. …

Analysis and interpretation of tidal currents in the coastal boundary layer
… to the semidiurnal and diurnal tides. The tidal ellipses, show considerable vertical structure. Near-surface tidal ellipses rotate in the clockwise direction for semidiurnal and diurnal tides, while near-bottom ellipses rotate in the counterclockwise direction for the semidiurnal tide. The angle …

Tales of (Dis)connection: Moving Through an Interconnected Europe in the Short Story, 1880–1930
… features which limit narrative length – summary, ellipses and a restricted scope for plot – lend themselves to thematizing various forms of limitation, including indifference, ignorance and inaction. The first chapter focuses on Hardy’s summary-heavy short story collection Life’s Little Ironies …

Searching for Constructed Form: A Station for Projective Geometry
… from the earth transitioning from squares to ellipses. The towers are cut mid-ascent to shape an eastern face, orienting the project and the rail traffic beneath.

Chebyshev-like polynomials, conic distribution of roots, and continued fractions
… the following; Chebyshev points lie on certain ellipses centered at the origin, and conversely, every such ellipse contains infinitely many sets of Chebyshev points. In special cases, the products of all curvatures at Chebyshev points can be expressed in terms of Fibonacci and Lucas numbers. …

Change Detection In Rhesus Monkeys and Humans
… the same change detection task (Aim 1), but with ellipses that varied in their height-to-width ratio so that their reliability of communicating orientation discrimination could be manipulated. The high-reliability ellipses were long and narrow, and the low-reliability ellipses were short and wide. …

A Polynomial Based Iterative Method for Linear Parabolic Equations
… to $f(z) = (1 - exp(-z))/z,f(0) = 1,$ over ellipses in the complex plane using expansions of f in Chebychev polynomials. The calculation of the Fourier Coefficients requires numerical integration over only a single line segment in the complex plane whose length and orientation depend on the …

Chromatic sensitivity: effects of light level and selective photoreceptor adaptation
… employed to measure colour detection threshold ellipses under different states of chromatic adaptation and background light levels. The advantage of this new technique is that it isolates the use of colour signals by embedding the isoluminant chromatic stimulus in dynamic luminance noise. These …

Dynamics and Equilibria of N Point Charges on a 2D Ellipse or a 3D Ellipsoid
… distribution is intuitively obvious) and ellipses. We then generalize the approach to the three dimensional case of an ellipsoid. The method we use is to begin with a random distribution of charges on the surface and allow each point charge to move tangentially to the surface due to the …

A natural interaction reasoning system for electronic circuit analysis in an educational setting
… first processed into primitives like lines or ellipses, then combined into the appropriate circuit device symbols using a shape description language called LADDER. The circuit is then solved by a constraint-propagation reasoning component. The solution is shown to the user along with the …

Stratification on the Skagit Bay tidal flats
… (near the north fork river mouth), velocity ellipses are nearly circular owing to strong alongshore tidal flows and alongshore stratification processes are important. Stratification was largest in areas where velocities and density gradients were aligned. The maximum stratification occurred …
