• A study of ultra-low-energy electron-molecule collisions using very-high-n Rydberg atoms ﻿

(1993)
In the present work very-high-n Rydberg-atoms $(n \sim 100 - n \sim 400)$ are used to probe electron-molecule collisions at ultra-low electron energies. Based on the essentially-free-electron model, for sufficiently high ...
• A study of university timetabling that blends graph coloring with the satisfaction of various essential and preferential conditions ﻿

(2004)
Constructing a satisfactory conflict-free semester-long timetable of courses and creating a similarly satisfactory conflict-free timetable for end-of-semester final examinations are two closely related and often difficult ...
• A study of Uranian magnetospheric convection ﻿

(1990)
In order to understand and explain the low-energy plasma structures observed by the PLS experiment on Voyager 2 in the Uranian inner magnetosphere, an analytic and self-consistent model of a time-dependent solar-wind driven ...
• A study of viscous effects in seismic modeling, imaging, and inversion: Methodology, computational aspects, and sensitivity ﻿

(1996)
Real Earth media are anelastic, which affects both the kinematics and dynamics of propagating waves: Waves are attenuated and dispersed. If anelastic effects are neglected, inversion and migration can yield erroneous ...

(1986)
• A study on conditions for sparse solution recovery in compressive sensing ﻿

(2008)
It is well-known by now that tinder suitable conditions &ell;1 minimization can recover sparse solutions to under-determined linear systems of equations. More precisely, by solving the convex optimization problem min{&par; ...
• A study on methane emission from rice paddy fields and the nonstructural carbohydrates in rice plants ﻿

(1993)
A dynamic process of the nonstructural carbohydrate translocation in rice plants is presented based on observation during one growing season. Differing amounts of nonstructural carbohydrates might be lost through rice ...

(1966)
• A study on the resistances to oxygen transport in the microcirculation ﻿

(1993)
A study on the resistances to oxygen transport in the microcirculation has been conducted. In Part I of this work, the oxygen permeability of cultured bovine aortic and human umbilical vein endothelial cell monolayers was ...
• A stylistic, contextual, and musical analysis of Rachmaninoff's "Rhapsody on a Theme of Paganini", Op. 43 ﻿

(2008)
This document explores the use of the theme from Paganini's 24 th Caprice and the Dies Irae in Rachmaninoff's Rhapsody on a Theme of Paganini, Op. 43. The two themes are studied from a historical and musical perspective, ...
• A subgradient algorithm for nonlinear integer programming and its parallel implementation ﻿

(1991)
This work concerns efficiently solving a class of nonlinear integer programming problems: min $\{f(x)$: $x \in \{0,1\}\sp{n}\}$ where $f(x)$ is a general nonlinear function. The notion of subgradient for the objective ...
• A summary of various neutron experiments ﻿

(1957)
The method to be discussed here is that of measuring the threshold energy for neutron production. Extensive discussions of this method are to be found in the literature. In particular we are concerned with neutrons resulting ...
• A suprathermal ion accelerator ﻿

(1967)
To facilitate calibration of the Rice ALSEP/SIDE instrument a low energy (thermal to 4.0 kev) positive ion beam of variable current density (10-12 to 10-8 amp/cm2) has been developed. A high perveance electron beam of 0.15 ...
• A SURFACE PHOTOMETRIC STUDY OF NGC 5128 ﻿

(1985)
Calibrated digital surface photometry in the standard UBV pass- bands has been used to prepare two dimensional maps to examine the structure and stellar populations in NGC 5128 (Cen A). The main body of the galaxy exhibits ...
• A survey of geophysical prospecting methods ﻿

(1948)
Existing geophysical prospecting methods were studied with the emphasis on reflection seismic practices. From the wave equation, the derivation of the transmission and reflection coefficients for plane polarized waves in ...
• A survey of stars and compact sources in the Orion Nebula ﻿

(1996)
Four monochromatic (H$\alpha$, (N II), (O III) and 5500 A continuum) mosaics of the inner region of the Orion Nebula have been made by using data obtained with the Wide Field Planetary Camera 2 of the Hubble Space Telescope. ...
• A survey of the factors affecting the labor force participation of married women with children ﻿

(1972)
Much of the recent literature on labor force participation points out that the most noticeable change in participation patterns has occured in the class of married women, with husbands present. Most of these studies also ...

(1954)
• A symmetry preserving singular value decomposition ﻿

(2007)
This thesis concentrates on the development, analysis, implementation, and application of a symmetry preserving singular value decomposition (SPSVD). This new factorization enhances the singular value decomposition (SVD)---a ...
