11. Virtual three-dimensional analysis of digitized dental impressions and stone replicas
Abstract : In response to increasing patient awareness of esthetic dental rehabilitation, the preference today is for all-ceramic restorations, which show superior biocompatibility and similar light characteristics to the natural tooth. The fit of a dental restoration depends on quality throughout the entire manufacturing process. READ MORE

12. Principles for modelling of manufacturing sequences
Abstract : The manufacturing sequence influence, to a large extent, component properties like fatigue life, shape accuracy and manufacturability. By simulating the manufacturing sequence, using numerical or empirical models, and extracting important accumulated data, like residual stress, hardness and shape, the possibilities of early analysis of a design concept and the associated manufacturing sequence will increase.

13. 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

14. On Functional Tolerances in Machine Design
Abstract : This thesis describes a method that allows tolerances on critical dimensions to be assigned with respect to both quality and manufacturing cost. To be able to quantify and include customer needs in the process of assigning tolerances, the concept of functionality loss is used. READ MORE
