Over the past four decades, the decline in the extent and thickness of Arctic sea ice has accelerated dramatically due to global warming. The rate of this decline is much faster than predicted by existing climate models. The evolution of the decline

Mechanical stress can affect structures in many ways. It can for example deform their shape, or alter their physical properties. These effects can have positive or negative outcomes such as rendering a structure more resistant or causing it to fail p

Current medical ultrasound imaging techniques generally require contact between the probe and the patient. In some cases, such as corneal imaging, this approach can be irritating and inconvenient for the patient. The objective of this thesis is to de
