16. Fast ions and turbulent particle transport in tokamaks
Abstract : The presence of highly energetic (fast) ions, be it fusion born alpha particles or ions accelerated by auxiliary heating schemes, can affect the heating and transport of all particles in the plasma through two main mechanisms. First, fast ions may excite fast ion driven instabilities. READ MORE

17. Particle Characterization in the Exhaust Devices of Direct Injection Engines
Abstract : Minimizing pollutants are of utmost importance to ensure sustainability in transportation. Particle emissions from internal combustion engines are especially harmful to human health, while also contributing to global warming. READ MORE

18. Experimental studies of materials migration in magnetic confinement fusion devices : Novel methods for measurement of macro particle migration, transport of atomic impurities and characterization of exposed surfaces
Abstract : During several decades of research and development in the field of Magnetically Confined Fusion (MCF) the preferred selection of materials for Plasma Facing Components (PFC) has changed repeatedly. Without doubt, endurance of the first wall will decide research availability and lifespan of the first International Thermonuclear Research Reactor (ITER). READ MORE

19. Gyrokinetic simulations of microturbulence and transport in tokamak plasmas
Abstract : Fusion power is one of few viable and sustainable means of energy production. The tokamak is arguable the most mature technology to magnetically confine fusion plasmas. In these devices, heat and particle transport is dominated by small-scale turbulent fluctuations. READ MORE

20. Hydrological Transport in Shallow Catchments: : tracer discharge, travel time and water age
Abstract : This focuses on hydrological transport in shallow catchments with topography-driven flow paths. The thesis gives new insight to kinematic pathway models for estimation of tracer discharge at the catchment outlet. READ MORE
