• #### An All Solid-State Laser System for Cooling and Trapping Lithium ﻿

(2013-09-16)
Ultra-cold atoms have become an essential tool in studying unique phenomena in condensed matter systems such as superconductivity and quantum phase transitions. To accomplish these experiments we use an apparatus designed ...
• #### An all-optical biological function generator and oscilloscope framework for characterizing gene circuit dynamics ﻿

(2014-04-21)
Gene circuits are dynamical systems that regulate cellular behaviors, often using protein signals as inputs and outputs. Here we have developed an optogenetic ‘function generator’ for programming tailor-made gene expression ...
• #### An alternative approach to differential semblance velocity analysis via normal moveout correction ﻿

(2010)
This thesis develops a new computation of the objective function and gradient for normal moveout-based differential semblance (DS). The DS principle underlies a class of algorithms for seismic velocity analysis. The simplest ...
• #### An Alternative Politics: Texas Baptist Leaders and the Rise of the Christian Right, 1960-1985 ﻿

(2012)
This dissertation examines one of the most counter-intuitive southern responses to the rise of the Christian Right. Texas Baptists made up the largest state association of Southern Baptists in the country. They were ...
• #### An analog to the heat equation in complex space variables ﻿

(1991)
Consider the operator$${\bf P} = {\partial\over\partial t} + \alpha{\partial\sp m\over \partial z\sp m},\qquad \alpha \in {\bf C} - \{0\}$$where $\partial\over{\partial z}$ is the usual complex operator:{\partial\over\partial ...
• #### An analysis of an optomotor reflex using methods from control theory, cross-correlation analysis, and information theory ﻿

(2003)
This report describes a novel approach to the question of how spike trains encode information. Traditional methods rely on signal processing techniques based on point process theory and focus on the relationship between ...
• #### An analysis of daylighting in the works of Alvar Aalto and Louis I. Kahn ﻿

(1989)
This thesis focuses on the manner in which two contemporaries, Alvar Aalto and Louis I. Kahn, each recognized the potential for and developed techniques toward the realization of daylighting's efficacy for the clarification ...
• #### An analysis of Debussy's "Sonata for Flute, Viola, and Harp" ﻿

(1988)
The Sonata for Flute, Viola, and Harp, written in 1915, is an excellent example of Claude Debussy's later style. The purpose of this thesis is to discuss the elements of this later style and represent them graphically. In ...
• #### An analysis of lightning and the limitations it imposes on a global model of thunderstorm electricity ﻿

(1990)
I report here on preliminary work incorporating transient effects from lightning into a global thunderstorm electricity model. First, E, the electric field produced by a lightning return stroke, is analytically derived. ...
• #### AN ANALYSIS OF LONGITUDE VARIATIONS IN THE EQUATORIAL SPECTRUM OF SATURN ﻿

(1987)
Ground-based and Voyager observations in and out of methane and ammonia bands are analyzed to search for longitudinal variations in Saturn's equatorial region. A model with reflecting layer at 2.1 bars, an extended haze ...
• #### AN ANALYSIS OF MELTING WITHIN A HORIZONTAL CYLINDRICAL ENCLOSURE ﻿

(1980)
An analysis of the melting process for a phase change material in which the solid density is greater than that of the liquid is presented. The mathematical model developed investigates the effect of unequal densities on ...
• #### An analysis of nonlinear damping and stiffness effects in force-limited random vibration testing ﻿

(1998)
The effects of both stiffness and damping nonlinearities on force-limited, random vibration test specifications are investigated. The response of the source-load vibratory system to a random, Gaussian excitation is analyzed ...
• #### An analysis of sorption in the field and the implications for transport and risk ﻿

(2000)
There is often a fraction of contaminants in the subsurface which is observed to persist for long periods of time and resist removal. The phenomenon of incomplete or slow desorption has been shown in the laboratory for ...
• #### An analysis of the between space in the experimental city (Texas) ﻿

(1993)
Houston is the rebellious younger sibling of the traditional city, a product of the tug-of-war between the amorphous historic past and the open field of future possibilities; this dichotomy contributes to the form of the ...
• #### An analysis of the effects of Soviet interventions on U.N. roll call voting ﻿

(1990)
The purpose of this thesis is to discover the effects of Soviet interventions on overall voting patterns in the General Assembly of the United Nations. Specifically, it endeavors to study how U.N. voting changed after the ...

(1975)
• #### An analysis of the impact of foreign collaborations on production, exports and imports in India ﻿

(1993)
This thesis examines at a micro-level the effect of foreign collaborations in India on trade and production. The data used is classified according to the Standard International Trade Classification (SITC). It is examined ...
• #### AN ANALYSIS OF THE MOTION OF PIGS THROUGH NATURAL GAS PIPELINES ﻿

(2011)
The dynamics of propelling a pig through a natural gas pipeline, using the gas being transported, are analyzed. The gas flow is assumed to be isothermal, quasi-steady, and one-dimensional. The pig is modeled as a cylinder. ...

(1978)
• #### An analysis of the WN shell nebula NGC 6888 using CCD imagery and spectrophotometry ﻿

(1991)
We present a model describing the morphology and physical processes in NGC 6888, a 'wind-blown' nebula around the WN6 star HD192163. CCD imagery with the Palomar 1.5m revealed distinct morphological features that were ...
