Accelerating radio transient detection using the Bispectrum algorithm and GPGPU by Lin, Tsu-Shiuan

“…In this thesis, we present a number of modified implementations of the bispectrum algorithm, allowing both instruction-level and data-level parallelism. Firstly, a multi-threaded CPU version is developed in C++ using OpenMP and then compared to a GPU version developed using Compute Unified Device Architecture (CUDA).In order to verify validity of the implementations presented, the implementations were firstly run on simulated data created from MeqTrees: a tool for simulating transients developed by the SKA. …”

Analytical perspectives on localized solutions of the phi-4 theory by Dika, Alain

“…The potential energy shows local minima surrounded by families of closed level surfaces. By selecting initial conditions that lie on the energy shell, the resulting trajectory will remain inside that level surface.…”

Thermo-chemo-mechanical modelling of hydropower structures affected by alkali silica reaction by Nyoni, Bukhosi Raphael

“…To this end, a number of numerical constitutive models have been developed to simulate ASR induced expansion in concrete. These models can generally be categorised as either, (i) microstructural models which aim to link the chemical process of the reaction to its impact at material level or (ii) macrostructural models which focus on the structural level assessment of affected concrete structures. …”
