11. Variable Valve Actuation in a Spark Ignition Engine - A Flow Field and Heat Release Study
Abstract : The objective of this thesis was to find ways of improving part-load efficiency for a spark ignition engine by studying the effects of variable-valve actuation on fluid flow and combustion. The in-cylinder flow was measured with laser doppler velocimetry, LDV, and particle image velocimetry, PIV. READ MORE

13. Towards Surface Engineering
Abstract : The purpose of this dissertation is to explore a route towards surface engineering both by the introduction of a conceptual framework called Interactive Surface Modelling (ISM) and by the actual application of the concept on two functional surfaces of importance to the automotive industry: cylinder liners for engines and leather imitation surfaces for the interior of cars. The results are presented in six separate but related papers concerning the construction of the ISM system shell and the use of modern technology to explore and represent the functional knowledge relevant to the specification of surface properties.

14. Aircraft Systems Conceptual Design : An object-oriented approach from to
Abstract : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.

15. DEM Modelling and Simulation of Cone Crushers and High Pressure Grinding Rolls
Abstract : The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills.
