• #### Absolute calibration of a retarding-potential Mott polarimeter ﻿

(1992)
Mott polarimeters are used in many areas of physics to determine the spin polarization of electrons in studies of processes dependent on the electron's intrinsic spin angular momentum and associated spin magnetic moment. ...
• #### Absolute differential and integral cross sections for charge transfer of state-selected keV oxygen ion with oxygen(2) ﻿

(1998)
Absolute differential and integral charge transfer cross sections have been measured for 0.5, 0.85, 1.5, 2.8, and 5.0 keV O$\sp+$ with O$\sb2$ at scattering angles between 0.01$\sp\circ$ and 3.50$\sp\circ$ in the laboratory ...
• #### Absolute differential cross sections for charge-transfer of keV-energy hydrogen ion and oxygen ion ions with atomic oxygen ﻿

(1989)
The major constituent in the atmosphere of the Earth at altitudes between 200 and 500km is atomic oxygen.$\sp1$ Collisions involving atomic oxygen are therefore important in this region of the atmosphere. Due to the ...
• #### Absolute differential cross sections for electron capture and loss by keV hydrogen atoms ﻿

(1990)
Absolute differential cross sections for electron capture and loss by neutral hydrogen atoms incident on various gases are presented. The measurements cover a laboratory angular range of 0.02$\sp\circ$ to 1.77$\sp\circ$ ...
• #### ABSOLUTE DIFFERENTIAL CROSS SECTIONS FOR SMALL-ANGLE NEUTRAL-NEUTRAL AND ION-NEUTRAL ELASTIC SCATTERING AT KEV ENERGIES ﻿

(1987)
This thesis reports measurements of absolute cross sections, differential in angle, for elastic scattering of keV-energy atomic H and He projectiles from He, Ne, Ar, Kr, Xe, H$\sb 2$, and N$\sb 2$ at laboratory scattering ...
• #### Absolute differential cross-sections for keV energy ion and atom collisions with oxygen atoms ﻿

(1990)
Oxygen atoms are the most abundant constituent in the Earth's atmosphere between 200km and 600km, and thus are the most probable targets for precipitating ions and atoms at these altitudes. Differential cross sections for ...
• #### ABSOLUTE DIFFERENTIAL CROSS-SECTIONS FOR SMALL-ANGLE CHARGE-TRANSFER COLLISIONS AT KEV ENERGIES ﻿

(1987)
Absolute differential cross sections for charge-transfer collisions of H$\sp{+}$ and He$\sp{+}$ with a variety of rare-gas- and molecular-gas-targets are presented. The cross sections are measured within the energy range ...

(1979)
• #### Absolute partial cross sections for electron-impact ionization of argon, hydrogen, nitrogen, oxygen, and carbon dioxide from threshold to 1000 eV ﻿

(1996)
Absolute partial cross sections from threshold to 1000 eV are reported for electron-impact ionization of Ar, H$\sb2$, N$\sb2$, O$\sb2$, and CO$\sb2$. Data are presented for the production of Ar$\sp{n+}\ (n=1{-}4)$ from Ar; ...
• #### Absorption and scattering of single plasmonic nanoparticles ﻿

(2010)
In this thesis, I present the absorption and scattering properties of single gold nanoparticles. I performed scanning electron microscopy (SEM) correlated dark-field scattering studies of gold nanorods (AuNRs). I found ...
• #### Abstract No. 1 for Orchestra ﻿

(2007)
Abstract No. 1 is motivated by the study of orchestral colors and solo instrumental timbres. The work is based on the idea of a bell. The first and last sounds of the piece are bell sounds and the large scale formal plan ...
• #### Abstraction and reinterpretation in architecture ﻿

(1999)
Design is a process of abstraction and reinterpretation of the world. Not only the physical world, but also the mental world. They are being abstracted, processed, transformed and reinterpreted in the design. The purpose ...
• #### Accelerated Discontinuous Galerkin Solvers with the Chebyshev Iterative Method on the Graphics Processing Unit ﻿

(2011)
This work demonstrates implementations of the discontinuous Galerkin (DG) method on graphics processing units (GPU), which deliver improved computational time compared to the conventional central processing unit (CPU). The ...
• #### Accelerated High-Performance Compressive Sensing using the Graphics Processing Unit ﻿

(2011)
This thesis demonstrates the advantages of new practical implementations of compressive sensing (CS) algorithms tailored for the graphics processing unit (CPU) using a software platform called Jacket. There exist many ...
• #### Accelerating the Arnoldi iteration: Theory and practice ﻿

(1998)
The Arnoldi iteration is widely used to compute a few eigenvalues of a large sparse or structured matrix. However, the method may suffer from slow convergence when the desired eigenvalues are not dominant or well separated. ...

(1973)
• #### ACCELERATION WAVES ﻿

(1984)
Three-dimensional acceleration waves are studied for a large class of materials which includes nonlinear elastic materials, finite linear viscoelastic materials, elastic-plastic materials, hypo-elastic materials, and ...

(1978)
• #### Access price determination in a vertically integrated industry ﻿

(1998)
We propose an access price determination approach, where the only regulatory instrument is the interconnection charge. Retail prices are set by unconstrained profit maximizing firms. We present a two stage model, solved ...
• #### Accessible and green manufacturing of magnetite (ferrous ferric oxide) nanocrystals and their use in magnetic separations ﻿

(2008)
This work describes the first size dependent magnetic separation in nanoscale. Magnetite (Fe3O4) nanocrystals of high quality and uniform size were synthesized with monodispersity below 10%. Magnetite nanocrystals of 4 nm ...
