1. Spirit of Christ Inculturated- A Theological Theme Implicit in Shusaku Endo's Literary Works
Sammanfattning : Shusaku Endo (1923-1996) is a Roman Catholic, Japanese novelist. From 1950 to 1953, he studied French literature in Lyon, France. Returning from Lyon, Endo began his career as a novelist. His early works include: White Men, Yellow Men(1954), A Wonderful Fool(1959), The Women in the Bible(1960), Foreign Studies(1965), etc. LÄS MER
2. On the surface quality of continuously cast steels and phosphor bronzes
Sammanfattning : This thesis work concerns about the importance of the cast surfaces, surface phenomenon such as the formation of the oscillation marks and exudation and related defects including cracks and segregation that happened during the continuous casting. All of the investigated materials were collected during the plant trials while an in-depth analysis on these materials was performed at the laboratory scale with certain explanations supported by the schematic and theoretical models.

3. On the Experimental Determination of Damping of Metals and Calculation of Thermal Stresses in Solidifying Shells
Sammanfattning : This thesis explores experimentally and theoretically two different aspects of the properties and behaviour of metals: their ability to damp noise and their susceptibility to crack when solidifying. The first part concerns intrinsic material damping, and is motivated by increased demands from society for reductions in noise emissions. LÄS MER
4. EMI from Switched Converters – Simulation Methods and Reduction Techniques
Sammanfattning : In this thesis, the conducted EMI from switched power converters has been analyzed using various existing models, own-derived models as well as measurements. The ingoing passive components in a switching converter have been modeled with respect to their high frequency behavior and the static and dynamic behavior of the active semiconductors has been analyzed.

5. Single Phase Active Power Factor Correction Converters - Methods for Optimizing EMI, Performance and Costs
Sammanfattning : In this thesis, front-end solutions with single-phase power factor correction (PFC) capability are studied. The reduction of current harmonics using various PFC techniques is investigated and related to the EN 61000-3-2 standard. LÄS MER
