Feasting on foreign aid : a political economic examination of foreign aid's potential role in perpetuating chronic hunger and starvation in Malawi
… a narrow set of indicators - such as economic growth - dictating the direction of policy for recipient nations wishing to maintain the inflow of aid. For Malawi, this is all but inevitable as foreign aid accounts for 40% of government revenue. As a result of this dependency on external income, …

Wave-current interaction in water of finite depth
… to be diffused downward, and induces further growth. Various contributions to the unstable growth of Langmuir circulation are analyzed by examining the mechanical energy budget. Evidences will be shown that the surface stress contributes significantly to instability. Both wave-following …

Stability of fluid-loaded structures
… scattering off the plate ends. We solve for the unstable resonance frequencies and temporal growth rates for long plates. We derive upper and lower bounds on the unstable growth rates of finite plates with given edge conditions. We find that a flag-like configuration of a clamped leading edge and …

Instabilities and flow-induced structures in anisotropic systems
… to control the self-amplified and non-linear growth that characterizes instabilities. In this thesis, we focus on fluid instabilities due to the adaptivity of fluids to their environments, and establish novel strategies to tune the growth morphology of interfacial instabilities and …

Response and Failure of Adhesively Bonded Automotive Composite Structures under Impact Loads
… element models. The chosen adhesive exhibited unstable, stick-slip crack growth, which resulted in very few data points being collected from each static DCB specimen as well as drastic drops in energy release rate between initiation and arrest points. Unstable growth also created issues in …

Experimental investigation of damage evolution during strain burst in brittle rocks for deep mines
… how this stored energy is released during the unstable spontaneous failure. Therefore, it is significant to investigate the energy state during strain burst from the viewpoint of energy theory. In this sense, circumferential strain controlled quasi-static tests on Class II rocks over a wide …
