Both experimentally and theoretically, the study of two-dimensional electron systems in strong magnetic fields is one of the most interesting topics in condensed-matter physics. In the presence of strong magnetic fields and low temperature the fractional quantum Hall effect (FQH…

This thesis is organized in two independent parts, in which I study two different aspects of high Tc superconductivity. The first part begins with an introduction aimed to briefly introduce some relevant experimental and theoretical works performed in recent years, that have hel…

Microscale breaking wave are short gravity waves that break without air entrainment. Microscale breaking waves occur at low to moderate wind speeds (i.e. 4–12 m s−1) and are typically O(0.1–1)m in length. This work reports on a series of laboratory experiments investigating the …

Inverted flags—clamped-free elastic thin plates subjected to a fluid flowing axially and directed from the free end towards the clamped end—have been observed experimentally and computationally to exhibit large-amplitude flapping beyond a critical flow velocity. The motivation f…

Current lean-premixed fuel injector designs have shown great potential in terms of reducing emissions of pollutants, but such designs are susceptible to combustion instabilities in which aerodynamic instability plays a major role and also has an effect on mixing of air and fuel.…
