16. Characterization of Glow Plug and HCCI Combustion Processes in a Small Volume at High Engine Speed - Load Range, Emission Characteristics and Optical Diagnostics
Abstract : The objective of this research that has taken me halfway to my PhD degree was to understand how HCCI combustion behaves in a small volume at high rotational speed. The investigation has been carried out using a modified model airplane engine. READ MORE

17. Characterization of the Homogeneous Charge Compression Ignition Combustion Process
Abstract : The main objective of this project was to characterize the HCCI combustion process. Central parts in the project were the progress of the HCCI combustion process, the influence of charge homogeneity on the combustion process and sources of UHC and CO emissions in HCCI combustion.

18. Measurement and Control of Metal Vapours during Fluidized Bed Combustion of Biomass Fuels
Abstract : Increased combustion of biomass fuels for heat and power production has created a need to recycle nutrient elements in biomass ash to soils to make the biomass consumption sustainable. It is, however, difficult to recycle the total amount of biomass ash produced due to the high concentrations of heavy metals and their readily soluble forms in some ash fractions. READ MORE

19. Development and Application of Non-linear Mid-infrared Laser Spectroscopy for Combustion Diagnostics
Abstract : The work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking accessible electronic (one-photon) transitions in the ultraviolet (UV) or visible spectral region.

20. Metal Hydrogen Interaction and Structural Characterization of Amorphous Materials from first principles
Abstract : In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe(1-x)Zrx. READ MORE
