Numerical methods for exascale magnetohydrodynamics simulations in general relativity
(2019-05-30)This work has two parts. In the first, we treat a problem in evolving partial differential equations numerically. Typical methods for such problems are unstable if the time step is too big. The maximum allowed time step ... -
Numerical Methods For Simulating Multiphase Flows With A Focus On Atomization
(2014-08-18)In this dissertation, numerical methods useful for the simulation of gas-liquid multiphase flows are presented. Multiphase flows are commonly found throughout nature, human life, and engineering devices. As a result, ... -
Numerical Modeling Of Gravitational Waves
(2009-10-13)Gravitational wave detectors such as LIGO are poised to detect signals from coalescing binary black hole systems. Such a detection would allow for the first time a test of general relativity in the strong-field regime. We ... -
Numerical Simulation Of Corrosive Dissolution And Stress-Induced Changes In The Reaction Rates.
(2013-01-28)This dissertation is composed of three chapters. Each chapter addresses a specific topic and has been, or will be, submitted as a journal article. The overarching theme connecting the content of the three chapters is the ... -
Numerical Simulations And Observations Of Equatorial F Region Plasma Irregularities
(2012-08-20)This dissertation describes a theoretical, experimental, and modeling investigation of the plasma irregularities in equatorial spread F (ESF). The primary scientific objective is to evaluate the electrodynamic nature of ... -
Numerical Simulations Of Black Hole Binaries: Second Order Spectral Methods
(2010-04-09)Current spectral simulations of Einstein's equations require writing the system in first-order form, potentially introducing instabilities and inefficiencies. This work presents a new penalty method for pseudo-spectral ... -
Numerical Simulations Of Generally Relativistic Hydrodynamic Systems
(2014-08-18)The study of binary neutron star coalescence, one the most energetic classes of events in the universe, requires calculating the complicated interactions of strong gravity, relativistic fluids, and magnetic fields. The ... -
Numerical Simulations Of Strongly Correlated Electron And Spin Systems
(2013-01-28)Developing analytical and numerical tools for strongly correlated systems is a central challenge for the condensed matter physics community. In the absence of exact solutions and controlled analytical approximations, ... -
Numerical Simulations Of Thermophoretic Drift Of Nanoparticles In Optical Trapping
(2015-08-17)Heat generation and its impact on transport of polystyrene beads in the proximity of an optofluidic silicon photonic crystal resonator and nanophotonic standing wave array traps are studied theoretically and simulated ... -
NUMERICAL SOLUTIONS FOR FINITE STRAIN CRACK TIP FIELDS IN SOFT INCOMPRESSIBLE SOLIDS
(2008-10-08)This dissertation concerns itself with problems involving cracks under finite deformation in incompressible hyperelastic materials with special application to soft materials. The main focus is on using numerical methods, ... -
Numerical Studies Of Black Hole-Neutron Star Binaries
(2011-08-31)Black hole-neutron star mergers are extremely energetic events with the potential to generate gravitational waves detectable by ground-based detectors. They can also form massive, hot accretion discs around a remnant black ... -
A Numerical Study Of The Slow Pyrolysis Of Thermally Thick Wood Spheres
(2014-01-27)Two one-dimensional numerical simulations were developed to model the pyrolysis of wood spheres, based on the proposed model developed by Park et al., 2010. Both of these models include physical processes coupled with a ... -
Numerically Accurate Rans/Pdf And Les/Pdf Calculations Of Turbulent Flames
(2010-08-05)Numerically accurate probability density function (PDF) calculations of turbulent jet flames are performed in the Reynolds-averaged Navier-Stokes (RANS) context. First, the effect is investigated of the time-averaging of ... -
Nurses As Neighbors: Community Health And The Origins Of School Nursing
(2014-05-25)This dissertation examines the origins and development of school nursing as an outgrowth of Progressive reform, especially in the settlement house movement. The Progressive stories of the rise of nursing and the transformation ... -
Nutrition And Dietary Diversity In East African Pastoralist Households: Mental Accounting, Market Failures And Intrahousehold Allocation
(2009-08-19)In this thesis I explore the determinants and intrahousehold allocation of nutrition in pastoralist households in northern Kenya and southern Ethiopia. Little economic research has been done on pastoralist households, ... -
NUTRITION, GUT MICROBIOTA, AND IMMUNE RESPONSE AMONG CHILDREN IN URBAN SLUMS OF MUMBAI
(2020-05)Background: The vicious cycle of poor nutrition status and impaired immune competence is particularly apparent in vulnerable populations, such as children living in urban slums. The gut microbiome likely modulates this ... -
Nutritional And Physiological Studies Of Oxalis Regnellii
(2011-01-31)Shamrock Plant (Oxalis regnellii) is an ornamental plant grown primarily for St. Patrick's Day. Interveinal chlorosis is a production problem and has been hypothesized to be caused by micronutrient deficiencies, either ... -
Nutritional Genomics of Pulmonary Function
(2019-08-30)Accelerated pulmonary function decline is a key risk factor for development of chronic obstructive pulmonary disease (COPD), the 3rd leading cause of death worldwide. Chronic inflammation is central to the pathogenesis of ... -
Nutritional Implications For Oxidative Status, Immune Function, And Energy Metabolism In Transition Dairy Cows And Relationships With Postpartum Performance And Endometritis
(2013-08-19)Factors associated with a failure to adapt metabolic and physiological regulation during the transition period include oxidative stress, metabolic disorders, and imbalanced energy status. Those factors are not only correlated ...
