11. Development and evaluation of hybrid joining for metals to polymers using friction stir welding
Sammanfattning : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. LÄS MER
12. Fatigue Assessment of Friction Stir Welded Joints in Aluminium Profiles
Sammanfattning : Friction stir welding (FSW) is a low heat input solid state welding technology. It is often used for fabrication of aluminium alloys in transportation applications including railway, shipbuilding, bridge structures and automotive components. LÄS MER
13. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature
Sammanfattning : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. LÄS MER

Sammanfattning : .... LÄS MER
15. Analysis and Design of Software-Based Optimal PID Controllers
Sammanfattning : A large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller.
