Hybrid Inverse Problems Arising from Acousto-Electric Coupling
… that aim to overcome the ill-posedness of the Electric Impedance Tomography using the acousto-electric coupling. For the isotropic case, we consider the problem of reconstructing the internal conductivity of an object by making electric measurements on the boundary while perturbing the …

Electrical impedance measurements of the uterine cervix in pregnancy
This is the first time that electrical impedance studies have been performed on the pregnant cervix.In this thesis the following has been demonstrated:1. An inter-observer variability in resistivity readings, initially of the order of 20%, but decreasing to 1% once proficiency with the technique …

Modeling the Motion of Solid Objects Immersed in Viscoelastic Fluids
… to improve the ways in which microrheology measurements are made and interpreted. This thesis aims to develop a flexible, adaptable framework for describing the motion of geometrically simple objects in weakly elastic fluids by adapting well-established and robust analytical methods. The …

Fundamental physics and application of plasma actuators for high-speed flows
… generated by laser energy, microwaves, and electric arc. The plasma generated by laser energy was also applied to a sonic transverse jet in a supersonic cross flow. Lastly, the particle image velocimetry diagnostic was considered and a technique developed to evaluate measurement uncertainty …
