On the warm bias along the South-West African Coast in coupled models : an oceanic perspective
Coupled ocean/atmosphere simulations exhibit systematicwarm biases over the SouthWest African (SWA) coastal region. Recent investigations indicate that coastal ocean dynamics may play an important role in determining the SST patterns, but none of them provide a detailed analysis. In this study, I …

Agent-based models to couple natural and human systems for watershed management analysis
… conventional physically-based environmental models with human factors for watershed management analysis. Using an agent-based modeling framework, two approaches, one based on optimization and the other on data mining-are applied to modeling farmers' pumping decision-making processes in the …

Hypolimnetic Oxygenation: Coupling Bubble-Plume and Reservoir Models
… bubble-plume diffusers. The unified suite of models, all based on simple discrete-bubble dynamics, represents the current state-of-the-art for designing systems to add oxygen to stratified lakes and reservoirs. An existing linear bubble plume model was improved, and data collected from a …

Holographic and Composite Models of the Axion
… by a novel strong interaction. Some strongly-coupled models, mathematically intractable until now, are recently discovered to be calculable through a mapping onto 5-dimensional gravity. We propose a series of composite and extra dimensional axion models. A basic 5-dimensional model first …

Modeled sensitivity of the northwestern Pacific upper-ocean responses to tropical cyclones in a fully coupled climate model with varying ocean grid resolution
… interactions are largely unexplored in fully-coupled models. Here we analyze the upper-ocean response to TCs using a high resolution Earth system model, in which a 0.5° atmosphere is coupled to an ocean with two different horizontal resolutions: 1° and 0.1°. The model produces realistic TCs up …

Effective reuse of coupling technologies for Earth System Models
Designing and implementing coupled Earth System Models (ESMs) is a challenge for climate scientists and software engineers alike. Coupled models incorporate two or more independent numerical models into a single application, allowing for the simulation of complex feedback effects. As ESMs increase …

Multi-Scale Modelling of Cold Regions Hydrology
… the hydrological cycle. Cold region hydrological models have requirements to calculate phase change in water via consideration of the energy balance which has high spatial variability. This motivates the inclusion of explicit spatial heterogeneity and field-testable process representations in such …

Sensitivity of climate change to diapycnal diffusivity in the ocean
… the least known parameters in cur- rent climate models. Measurements of this diffusivity are sparse and insufficient for compiling a global map. Inferences from inverse methods and energy budget calculations suggests as much as a factor of 5 difference in the global mean value of the diapycnal …

Modeling the processes affecting larval haddock (Melanogrammus aeglefinus) survival on Georges Bank
… the planktonic larval stage. Spatially explicit coupled biological-physical individual-based models are ideal for studying the processes of feeding, growth, and predation during the larval stage. This thesis sought new insights into the mechanisms controlling the recruitment process in fish …

Dynamics and Control of a Pressurized Optical Membranes
… achieve this end goal, two structural-acoustic coupled models are developed to describe the dynamics of a pressurized optical membrane system. This is done through an impedance based modeling approach where the subsystems are modeled individually, and then coupled at the interface. The control …

3D FE simulation of the welding process to optimise residual stress profiles in complex geometries
… boundary conditions, sequentially versus fully coupled models, were investigated. A 3D sequentially coupled model with standard constraint was then proposed and applied to multipass butt-welded plates and pipes for validation. Good agreements between the predictions and independent experimental …

Integrated Modeling and Optimization of Stormwater Control Measures for Sustainable Watershed Management Under Urbanization and Changing Rainfall Patterns
… To improve resilience in these complex systems, coupled models are essential. While SWAT and SWMM are widely used for runoff simulation, neither can independently represent both urban and rural hydrology. Moreover, most studies assess either CC or land use/land cover (LULC) change in isolation, …

Multiscale models of the metalorganic vapor phase epitaxy process
… growing film. In this thesis, new computational models are developed that work on specific length scales, models are linked together, and combined models are used to study the physics of actual deposition processes. A Kinetic Monte Carlo (KMC) model is developed in order to simulate surface …

Predicting water quality effects on bay anchovy (Anchoa mitchilli) growth and production in Chesapeake Bay: linking water quality and individual-based fish models
… fish is generally unknown as most water quality models do not include trophic levels higher than zooplankton. I combined two water quality models with bay anchovy models (Anchoa mitchilli) to examine the effects of changes in nutrient loadings on anchovy survival and growth. An individual-based …

ESTIMATION OF DIFFERENT COAL COMPRESSIBILITIES OF COALBED METHANE RESERVOIRS UNDER REPLICATED IN SITU CONDITION
… In this study, different coal compressibility models were developed based on the assumption that the deformation of a depleting coalbed is limited to the vertical direction, that is, the reservoir is under uniaxial strain conditions. Simultaneously, experimental work was carried out replicating …
