Recovery status and chemosensory cues affecting reproduction of freshwater mussels in the North Fork Holston River downstream of Saltville, Virginia
The freshwater mussel fauna of the North Fork Holston River (NFHR) downstream of Saltville, VA declined from at least 24 species, as observed in 1918, to one species in 1974 due to mercury pollution. To determine the degree of recovery of mussels in the NFHR downstream of Saltville, and to provide …

Fully Integrated CMOS-compatible mode-locked lasers
… and ranging, optical sensing, bio-medical diagnostics and imaging, and military-related applications. Large and complex radio-frequency and optical systems could be potentially replaced with compact, power-ecient, alignment-free, cost-effectively mass-produced integrated photonics components. …

Complexity of union-split-find problems
… word RAM model. For General Union-Split-Find, no o(n) bound is known. We present a data structure which has an [Omega](log2 n) amortized lower bound in the worst case that we conjecture has polylogarithmic amortized performance. This thesis is the product of joint work with Erik Demaine.

New bounds on optimal binary search trees
… in practical programs, surprisingly little is known about their optimal performance. No polynomial time algorithm is known to compute the best BST for a given sequence of key accesses, and before our work, no o(log n)-competitive online BST data structures were known to exist. In this thesis, we …

The effect of alternative fuels and aftertreatment devices on measured mobile school bus emissions
… Sensors Semtech-D to measure CO, CO<sub>2</sub>, NO<sub>2</sub>, NO, O<sub>2</sub>, and HC, along with a Sensors PM-300 to measure Particulate Matter (PM). In addition to the exhaust emissions measurements, instantaneous vehicle speed, engine speed, percent load and fuel flowrate were acquired …

Homodyne High-harmonic Spectroscopy: Coherent Imaging of a Unimolecular Chemical Reaction
… Second, extending it to a triatomic (NO2) lets us observe both the previously unseen (but predicted) early femtosecond conical intersection dynamics followed by the late picosecond statistical photodissociation taking place in the reaction NO2 to NO + O. Another important realization …

X-ray scattering studies of strongly correlated materials: orbital ordering in KCuF3 and stripe-like domain structures in BiFeO3 epitaxial thin films
… Both resonant soft x-ray elastic scattering and non-resonant hard x-ray elastic scattering probes were used. Our experiments on KCuF3 have revealed a previously unidentified structural phase transition at T = 50 K, involving GdFeO3 like rotations of the CuF6 octahedra. These rotations are …

A finite element segregated method for thermo-chemical equilibrium and nonequilibrium hypersonic flows using adapted grids
… 2-D hypersonic, thermo-chemical equilibrium and nonequilibrium flows, with an emphasis on resolving directional flow features, such as shocks, by an anisotropic mesh adaptation procedure. Since the flow field of such problems is chemically reacting and molecular species are vibrationally excited, …

A structure-reactivity study of selected phosphorus compounds
… (R)PhNHP(OCH₃)₂, (R = p-OMe, H, p-NO₂, o-Et and 2,6-diMe) have confirmed the preference of the phosphoramidates for dimer formation which was proposed earlier from infrared data. The formation of N - H - - - - O = P hydrogen bonded dimeric species is sensitive to steric effects and …

Synthesis and characteristic chemistry of sixteen-electron group 6 hydrocarbyl-containing nitrosyl complexes
This thesis addresses the non-generality of the previous method used to prepare CpW(NO)(alkyl)2 complexes from their diiodide precursors. The three most significant problems inherent to the original synthetic method were: (a) the reagents being used (i.e. transition-metal dihalide, alkylating agent …

School bus idling and mobile diesel emissions testing: effect of fuel type and development of a mobile test cycle
… school bus emissions during idling conditions, another objective of the school bus idling experiments was to develop a NO<sub>x</sub> humidity correlation for use in mobile school bus emissions testing, the first phase of which is presented herein. The results of the idle testing provide evidence …
