Collapses of linearly decaying three-dimensional perturbations in homogeneous and weakly stratified boundary layers (2020)
Thesis
Oloo, J. O. (2020). Collapses of linearly decaying three-dimensional perturbations in homogeneous and weakly stratified boundary layers. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/418970

The physical mechanisms of why an orderly laminar flow suddenly becomes turbulent are still poorly understood, despite more than a century of incessant efforts. The thesis puts forward a radically new approach to understanding of the fundamental chal...

Non-Newtonian and non-isothermal effects in the gravity-driven draining of a vertically-aligned thin liquid film (2020)
Thesis
Alahmadi, H. N. (2020). Non-Newtonian and non-isothermal effects in the gravity-driven draining of a vertically-aligned thin liquid film. (Thesis). Keele University

The drainage and thinning of liquid films are important in a variety of applications,such as in liquid and solid foam networks, relevant in the manufacture of metallic and ceramic foams, the food industry, processing in the petro-chemical industry, a...

Assessing the usability of virtual learning environments in higher education (2020)
Thesis
Abuhlfaia, K. M. O. (2020). Assessing the usability of virtual learning environments in higher education. (Thesis). Keele University

Context: E-learning is an integral part of the modern higher education system, and therefore it is essential that students and staff are able to use systems that support E-learning, such as Virtual Learning Environments (VLEs), effectively. Usability... Read More about Assessing the usability of virtual learning environments in higher education.

Mathematical modelling of cartilage and bone defect healing after cell implantation (2020)
Thesis
Campbell, K. (2020). Mathematical modelling of cartilage and bone defect healing after cell implantation. (Thesis). Keele University

This thesis is concerned with mathematically modelling the regeneration of cartilage and cartilage-bone defects. Defects of the bone-cartilage unit, namely chondral and osteochondral defects, are a leading cause of osteoarthritis, the most common typ...

Long wave anti-plane motion in pre-stressed elastic laminates (2020)
Thesis
Mohammed Helmi, M. (2020). Long wave anti-plane motion in pre-stressed elastic laminates. (Thesis). Keele University

The propagation of long waves along pre-stressed compressible elastic laminates is considered, focusing on anti-plane shear type waves. Within this thesis we investigate the mechanical response of this type of motion for a class of compressible pre-s... Read More about Long wave anti-plane motion in pre-stressed elastic laminates.

Hopf-Galois module structure of a class of tame quaternionic fields (2020)
Thesis
Taylor, S. J. (2020). Hopf-Galois module structure of a class of tame quaternionic fields. (Thesis). Keele University

We study the Hopf-Galois module structure of rings of integers in tame Galois extensions L=F of global fields with Galois group isomorphic to the quaternion group of order 8. We determine explicitly the Hopf algebras giving Hopf-Galois structures on... Read More about Hopf-Galois module structure of a class of tame quaternionic fields.

Control and suppression of elastic waves using periodic metasurfaces and bridges (2020)
Thesis
Wootton, P. T. (2020). Control and suppression of elastic waves using periodic metasurfaces and bridges. (Thesis). Keele University

This thesis discusses how wave propagation in continuous linearly elastic media can be controlled or suppressed using periodic structures. This involves controlling 2D waves on a membrane, 3D longitudinal and transverse waves in a linearly elastic bu...

Localized bulging in an inflated hyperelastic tube: the effects of rotation, multi-layering and torsion (2020)
Thesis
Althobaiti, A. A. K. (2020). Localized bulging in an inflated hyperelastic tube: the effects of rotation, multi-layering and torsion. (Thesis). Keele University

In this thesis, we start by considering a hyperelastic circular solid cylinder or tube that is rotating about its axis of symmetry with angular velocity ω. If the resultant axial force F is fixed, it is shown that the bifurcation condition for a soli...

Evolving developmental, recurrent and convolutional neural networks for deliberate motion planning in sparse reward tasks (2020)
Thesis
Jolley, B. P. (2020). Evolving developmental, recurrent and convolutional neural networks for deliberate motion planning in sparse reward tasks. (Thesis). Keele University

Motion planning algorithms have seen a diverse set of approaches in a variety of disciplines. In the domain of artificial evolutionary systems, motion planning has been included in models to achieve sophisticated deliberate behaviours. These algorith...

Dynamic chirality and failure in structured materials with applications (2020)
Thesis
Garau, M. (2020). Dynamic chirality and failure in structured materials with applications. (Thesis). Keele University

We consider the vibration of two classes of discrete periodic systems and the resulting dynamic effects. We analyse elastic lattices connected to arrays of gyroscopic spinners, that confer chirality to the elastic system. It is shown in the time-harm...
