A Langrangian decomposition approach to weakly coupled dynamic optimization problems and its applications
We present a Lagrangian based approach to decoupling weakly coupled dynamic optimization problems for both finite and infinite horizon problems. The main contributions of this dissertation are: (i) We develop methods for obtaining bounds on the optimal cost based on solving low dimensional dynamic …

Coupling of nanofluid flow, heat transfer and nanoparticles sedimentation using OpenFOAM
… developed OpenFOAM solvers under both Eulerian-Langrangian and Eulerian-Mixture (a simplified Eulerian-Eulerian approach) frames. By comparing present numerical results to previous published experimental and numerical investigations, it can be concluded that the newly developed solvers under …

Enlightening Artificial Intelligence with Science
… laws, hidden symmetries, integrable systems, Langrangian and Hamiltonian formulations, modular structures, and high-precion solutions. I believe my research work contributes to the emerging interdiscipinary field that unites AI and Science. Building opon the foundation laid in this thesis, I …

Modelling atmospheric dispersal of fungal pathogens on continental scales to safeguard global wheat production
… meteorological model data. The UK Met Office’s Langrangian stochastic particle dispersion model, NAME, is applied, extended and coupled to other models in a set of case studies. In the first case study, spore dispersal is analysed across Southern/East Africa, the Middle East, and Central/South …

An investigation of the response of different materials to blast loading
… elements while the test plates were modelled as Langrangian shell elements. Since the geometry of the plates was square, the simulations had to be performed in 3D quarter-symmetry. The transient response, permanent final displacement and maximum transient displacement of the numerical simulations …

Lagrangian Points and Jacobi Constants for a Class of Asteroids
<p>Asteroid Gravitational Potentials are difficult to model owing to their irregularity in shape. This thesis focuses on two approaches to model asteroid gravity fields, namely, multiple-body and spherical harmonics modeling. Computation of gravity potential serves as a first step to determine …

SPH Modeling of Solitary Waves and Resulting Hydrodynamic Forces on Vertical and Sloping Walls
Currently, the accurate prediction of the impact of an extreme wave on infrastructure located near shore is difficult to assess. There is a lack of established methods to accurately quantify these impacts. Extreme waves, such as tsunamis generate, through breaking, extremely powerful hydraulic …
