• #### Vacuum Bloch-Siegert Shift in Landau Polaritons with Ultrahigh Cooperativity ﻿

(2018-02-02)
A two-level system resonantly interacting with an ac magnetic or electric field constitutes the physical basis of diverse phenomena and technologies, including nuclear magnetic resonance, stimulated emission, amplification, ...
• #### Validation of Rice Parallel Processing Testbed applications ﻿

(1989)
The Rice Parallel Processing Testbed (RPPT) is a collection of software tools for simulating the interaction of parallel programs and parallel architectures. The testbed uses a novel technique called execution-driven ...
• #### Validation of the Rice Parallel Processing Testbed using sorting algorithms (Rice University, Texas) ﻿

(1989)
The Rice Parallel Processing Testbed (RPPT) is software package for simulating the execution of parallel computers. The RPPT employs execution driven simulation to perform simulation efficiently. In this thesis, the ...

• #### Value-driven redundancy elimination ﻿

(1996)
Value-driven redundancy elimination is a combination of value numbering and code motion. Value numbering is an optimization that assigns numbers to values in such a way that two values are assigned the same number if the ...
• #### Van der Waals interactions in density functional theory ﻿

(1998)
Various density functional methods have been tested for the van der Waals interactions of the rare gas dimers He$\rm\sb2,\ Ne\sb2$ and Ar$\sb2$ as model compounds. Detailed analysis proved that all tested and commonly used ...
• #### Van der Waals model of liquid wetting layers ﻿

(1989)
A phenomenological theory of wetting layer systems based on the van der Waals theory of interfaces is developed. For classical critical exponents the local composition profile and the wetting layer thickness are determined ...
• #### Vapor-liquid equilibria at moderate pressures: the ethylene glycol-methane-hydrogen sulfide system ﻿

(1961)
The objectives of this research were: To study the solubilities of Methane in Ethylene Glycol from 82 degrees F to 220 degrees F for pressures up to 2,000 lbs. per sq. in. To study the vapor - liquid equilibria of the ...
• #### Vapor-liquid equilibria in the system hydrogen-nitrogen-carbon monoxide ﻿

(1957)
Vapor-liquid equilibrium compositions for the system hydrogen-nitrogen-carbon monoxide were determined at -310&deg;F, and -280&deg;F and -240&deg;F from 300 psig to the critical. PVT data for hydrogen were fitted to the ...

• #### Variable length chain coding with applications ﻿

(1979)
A special scheme for coding a digitized picture is presented. This scheme encodes a picture by coding boundaries of areas in the picture as sets of line segments. It is shown that this scheme is superior to the conventional ...
• #### Variance Spectroscopy and its Application to the Study of Single-Wall Carbon Nanotubes ﻿

(2018-04-16)
This thesis describes the novel method of variance spectroscopy and its application to characterize single-wall carbon nanotube (SWCNT) dispersions. This technique measures and analyzes changes in photoluminescence intensity ...
• #### VARIATION IN SPECIES INTERACTIONS AND THEIR EVOLUTIONARY CONSEQUENCES ﻿

(2013-05-13)
Species interactions restrict or promote population growth, structure communities, and contribute to evolution of diverse taxa. I seek to understand how multiple species interactions are maintained, how human altered species ...
• #### Variational approaches to the molecular electronic structure problem based on symmetry-projected Hartree--Fock configurations ﻿

(2013-09-05)
Approximate wavefunctions such as Hartree--Fock (HF) states need not respect the symmetries of the molecular electronic Hamiltonian. In certain cases, the lowest-energy HF solution obtained by a variational scheme does not ...
• #### Variational multiscale methods for turbulence control ﻿

(2003)
Large Eddy Simulation (LES) is an efficient computational tool for turbulence simulation. Variational Multiscale (VMS) is a new paradigm for LES that uses variational projection instead of spatial filtering that obviates ...
• #### Variational problems in intersection homology theory and optimal transport ﻿

(2002)
This thesis studies geometric variational problems derived from intersection homology theory of singular varieties as well as from optimal transportation. Part I: Intersection homology theory via rectifiable currents . ...
• #### Variational problems with multiple-valued functions and mappings ﻿

(2001)
The thesis discusses the regularity problems of Dirichlet-minimizing multiple-valued mappings and stationary-harmonic multiple-valued functions. It consists of two chapters: Chapter 1. Interior partial regularity of ...
• #### 'Variational' optimization in quantum field theory ﻿

(1993)
We examine two different techniques for studying quantum field theories in which a 'variational' optimization of parameters plays a crucial role. In the context of the O(N)-symmetric $\lambda\phi\sp4$ theory we discuss ...
• #### Variations in formal structures of neighborhood organizations and their effects on member involvement ﻿

(1994)
The question of what effect formal structures of neighborhood organizations have on member involvement has largely been ignored in the body of research on neighborhood politics. Yet mandatory and voluntary neighborhood ...
• #### Variations in glucose diffusion coefficients in biological flocs ﻿

(1974)
The diffusion coefficient of glucose was measured in biological flocs under various growth conditions. Significant differences were observed with different carbon sources and carbon to nitrogen ratios. The diffusion ...
