Fluctuating concentrations in atmospheric dispersion
This thesis presents theoretical models and experimental results of average and instantaneous concentration measurements from a series of atmospheric dispersion experiments conducted under both unstable and stable meteorological conditions. The experiments were undertaken at two different sites, …

Probabilistic methods applied to fluctuating systems
In this work the hierarchical structure of three diverse stochastic systems is studied by investigating the probability densities of their scale-dependent measures across various scales. In the first system studied, velocity increments are used to investigate the order of complexity and disorder of …

Theory and Applications of Fluctuating-Charge Models
Fluctuating-charge models are computationally efficient methods of treating polarization and charge-transfer phenomena in molecular mechanics and classical molecular dynamics simulations. They are also theoretically appealing as they are minimally parameterized, with parameters corresponding to the …

Improving speech intelligibility in fluctuating background interference
… release (MR; i.e., better speech recognition in fluctuating compared to continuous noise backgrounds) that is evident for normal-hearing (NH) listeners is generally reduced or absent in hearing-impaired (HI) listeners. In this study, a signal-processing technique was developed to improve MR in HI …

Variation in fluctuating asymmetry among nine damselfly species.
Fluctuating asymmetry (FA), measured as random deviations from bilateral symmetry, likely results from developmental disturbances by internal or environmental stresses. However, comparisons of FA in single damselfly species (Odonata: suborder Zygoptera) from stressed environments have often been …

Characterization and Modeling of Fluctuating Hypoxia in Breast Cancer
… theoretical model, we examine the effects of fluctuating hypoxia on metabolized tirapazamine concentration; we find that fluctuating oxygen reduces the concentration of metabolized tirapazamine at distances farther from the source, thereby limiting its ability to reach and kill the most …

Simulation of fluctuating wind pressures on low building roofs
Wind pressure fluctuations acting on low building roofs are important for the prediction of peak pressure values and for fatigue design purposes. Collection of several time histories of pressure fluctuations, using traditional wind tunnel measurements is time consuming and expensive. Within this …

Rehumanising knowledge work through fluctuating support networks: a grounded theory
… a theory of rehumanising knowledge work through fluctuating support networks in the knowledge workplace. Data consisted of field notes and transcripts from personal interviews and focus groups. Participants were drawn from the public and private sectors and a variety of professional fields under …

Interactive embankment: topography of fluctuating water levels and human interaction
… address better riverbank design treatments for fluctuating water levels. It starts by investigating speculative and un-built edge conditions found in architectural and landscape renderings. Existing and speculative (un-built but visualized) interactive embankment types will be categorized and …

Enhanced transport through confined channels by stationary and fluctuating potentials
Binding-sites which facilitate the transport of substrates across membranes are ubiquitous in membrane proteins. To understand this fundamental process in cells, we build up a synthetic membrane system consisting of microfluidic channels and colloidal particles. Holographic optical tweezers are …

Fluctuating interfaces and paths in disordered and non-equilibrium systems
In this thesis, we study the statistics of fluctuating paths and interfaces in the presence of disorder. Specifically, we consider systems in the Kardar-Parisi-Zhang universality class for stochastic interface growth, from the perspectives of both fundamental statistical mechanics and applications …

Fluctuating and Phase -Stiff Proximity-Induced Superconductivity in Superconductor-Semiconductor Junctions
… nearby the junction interface. A transition from fluctuating to phase-stiff proximity induced superconductivity is observed in the semiconductor at temperatures often well below the transition temperature of the superconductor. This phenomenological interpretation is supported by the fact that the …

Fluctuating asymmetry as a measure of developmental instability in Arikara bioarchaeological assemblages
Fluctuating asymmetry (FA) has been advanced as a tool for investigating the developmental instability of human populations and has more recently found its way into bioarchaeological investigations. The research presented here seeks to build upon those investigations and determine whether specific …

A model for Arctic Charr populations in Cambridge Bay considering fluctuating environment
… fitness of such a population might change in a fluctuating environment. We assume three types of yearly environments; good, intermediate and bad. A discrete time Markov chain governs the transitions between environmental states. The results in this step also suggest a weak ergodic behaviour for …

Fluctuating Velocity-Pressure Field Structure in a Round Jet Turbulent Mixing Region
An experimental study of turbulent mixing has been conducted to provide detailed insight regarding the turbulent transport processes, especially those involving pressure. The investigation was conducted in the mixing region of a 6.35 cm diameter, isothermal, stationary jet having an exit velocity …
