1. The role of piston bowl shape in controlling soot emissions from heavy-duty Diesel engines
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : The role of piston bowl shape in controlling soot emissions from heavy-duty Diesel engines. Diesel combustion is often subject to a trade-off between emissions of soot and nitrogen oxides (NOx). READ MORE

2. On tribological design in gear tooth contacts
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.

3. Perceived Quality of Cars. A Novel Framework and Evaluation Methodology
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : The supremacy of the automotive manufacturers today is no longer driven by them achieving a superior manufacturing quality but increasingly depends on the customer’s quality perception. Average car consumers see a car’s quality as a fancy mixture of design, aesthetics, their own previous experiences and performance characteristics of the vehicle, unlike a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved in the modern car creation.

5. Affective Surface Engineering for Product Design
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : Design research, sensation and perception, hard metrology, emotional functions, semantics, surface roughness, product interaction, core values, total appearance… the list of scientific phrases never ends. Yet, what do they mean and how shall we use it when we are communicating with the industry and our end users? Is it possible to link the product experience to process parameters, put a number onto it? When you can measure spoken needs or even better, implied needs, of a product, and relate that data to the production, it is possible do create advanced products with high interaction stimuli.
