2. Mechanics and tribology of micro- and nanolayered PVD coatings
Sammanfattning : Thin coatings produced by physical vapour deposition (PVD) are increasingly applied tomechanical components such as metal cutting tools, forming tools and machine elements.Improved micro- and nanolayered PVD coatings have been studied with respect tomechanical and tribological properties.

3. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals
Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER
4. Workpiece steels protecting cutting tools from wear : A study of the effects of alloying elements on material transfer and coating damage mechanisms
Sammanfattning : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.

5. Heart rate variability and pacemaker treatment in children with Fontan circulation
Sammanfattning : Background: Fontan surgery is performed in children with univentricular heart defects. Arrhythmias are frequent complications, occasionally requiring pacemaker treatment. Previous data regarding indications and risk factors for pacemaker treatment in Fontan patients is limited and conflicting. LÄS MER
