Analysis of the dynamic behaviour of the hangingwall beam during a seismic event
… although the hangingwall response spectrum is shifted to a higher frequency and velocity domain, the shapes of the two spectra are essentially the same. The frequency and velocity shift is calculated for 15 seismic events and empirical rules are developed to quantify the spectral shift for a …

How Do Quasars Impact Their Host Galaxies? From the Studies of Quasar Outflows in Absorption and Emission
… One mechanism for such a coupling is by high-velocity (up to ~0.2c) quasar-driven ionized outflows, appearing as blue-shifted absorption and emission lines in quasar spectra. Given enough energy and momentum, these outflows are capable of affecting the evolution of their host galaxies. This …

Effects of surface roughness on the flow characteristics in a turbulent boundary layer
… that require understanding of the mean velocity and turbulence in the immediate vicinity of the roughness elements. This thesis reports the effects of surface roughness on the flow characteristics in a turbulent boundary layer. Both experimental and numerical investigations are used in …
