A web-based approach for post-processing large ensembles
… Fluid Dynamics (CFD) allow for quick creation of large ensembles of CFD results, making data analysis the bottleneck of the design process. Accelerating analysis of large CFD simulation ensembles is key to accelerating future design campaigns. The goal of CFD ensemble analysis is to support …

Sensing and timekeeping using a light-trapping diamond waveguide
… diamond waveguide structures to efficiently use large ensembles of NV centers (> 10¹⁰). Temperature-stabilized precision magnetometry, thermometry, and electrometry are discussed. In addition, the precision characterization of the NV ground state structure under a transverse magnetic field and …

364 Days: Suite for Jazz Orchestra
… for the album J.E. Chapman, 364 Days: music for large ensembles. Each movement of the suite is intended to work as a part of the larger work or out of context as an individual performance piece. The sections of the suite are connected through an "affiliated motif". Each piece is tied together …

Aqueous systems from first-principles : structure, dynamics and electron-transfer reactions
… are then constructed from umbrella sampling on large ensembles of configurations. As a paradigmatic case study, the self-exchange reaction between ferrous and ferric ions in water is studied in detail. Since the solvent plays an central role in mediating the process, studying electron-transfer …

A multiple case study of the ensemble experiences of three collegiate brass instrumentalists with physical disabilities
… of their motivation to persist in instrumental ensembles. This study was guided by two main research questions. The first main question was: (1) What are the perceptions of collegiate brass instrumentalists with physical disabilities regarding participation in instrumental large ensembles? The …

Computational Techniques for the Analysis of Large Scale Biological Systems
… mutant strain cells. In order to efficiently run large ensembles to compute statistics of cell evolution, the dissertation investigates parallel simulation strategies, and presents a new probabilistic framework to analyze the performance of dynamic load balancing algorithms. This work also …

Assessment of the impacts of climate change, land cover transition, and internal climate variability on the hydrology of a forested watershed
… Project Phase 5 (CMIP5) and three large ensembles (50 members) of Regional Climate Model (RCM) simulations, under the Representative Concentration Pathway (RCP) 8.5, are used to characterize the role of anthropogenic forcing and internal climate variability in projected changes of …

Synchronization of oscillatory networks in terms of global variables
Synchronization of large ensembles of oscillators is an omnipresent phenomenon observed in different fields of science like physics, engineering, life sciences, etc. The most simple setup is that of globally coupled phase oscillators, where all the oscillators contribute to a global field which …

Biophysics of Helices: Devices, Bacteria and Viruses
… First, the ability to selectively control large ensembles and second, the adaptivity to move through complex conduit geometries, such as the constrictions and curves of the tortuous tumour microvasculature. In this dissertation, a mechanics-based selective control mechanism for magnetic …

Low Energy Ion Beam Synthesis of Si Nanocrystals for Nonvolatile Memories - Modeling and Process Simulations
… is necessary to span the timescales involved. Large ensembles of Si NCs were simulated reaching the late stages of NC formation and dissolution at simulation sizes that allowed a direct comparison with experimental studies, e.g. with electron energy loss resolved TEM investigations. These …

Downward influence of stratospheric final warming events in an idealized model
… final warming is initiated from the stratosphere. Large ensembles of final warmings are simulated in an idealized dynamical core model, by imposing a radiative equilibrium temperature transition from winter to summer only in the stratosphere. Our results suggest that a substantial fraction of the …

Understanding ozone, climate and their interactions with causal machine learning
… 3, we explore the trade-offs when building large deep learning models for ozone air pollution forecasting, an important task to predict risks to human health. We develop a state-of-the-art transformer to forecast ground-level ozone, finding that the model forecasts with high accuracy across …

Tropical Cyclone Risk Assessment Using Statistical Models
… a need for statistical models that can simulate large ensembles of TCs in order to cover the full range of possible activity that results from a given climate change. I construct and apply a statistical track model from the 1945-2007 observed "best tracks" in the IBTrACS database for the WNP. The …

Compressibility effects on large-scale structures and entrainment in turbulent planar mixing layers
… via stereoscopic particle image velocimetry. Large ensembles (> 3000) of instantaneous measurements are obtained to confirm fully-developed, self-similar conditions of the mean velocity and each component of the Reynolds stress tensor. Transverse-spanwise plane velocity measurements are also …

Motility-induced phases: out-of-equilibrium droplets, surfaces, and survival
… which become particularly interesting at scales larger than the individuals, where we find emergent collective behavior like flocking and morphogenetic self-organization, respectively. One can study both microscopic and macroscopic behaviors of these particles using theory, simulation, and …

Three-dimensional turbulence mechanisms in a supersonic separated/reattaching longitudinal cylinder wake
… all three components of velocity along a large planar region, and tomographic PIV (TPIV), which measures all three components of velocity throughout a volumetric region. Large ensembles of measurement samples were acquired and processed for each set of experiments, which allowed for …

Energy Policy Impacts on Air Quality and Climate at the National, Regional and Global Scale
… species, with the aim of allowing us to examine large ensembles of social scenarios without the high computational costs of CTMs. Using Green's functions (a form of impulse response function) to represent the transport of Black Carbon (BC) in Southeast Asia (SEA), I define a wide range of policy …
