1. Towards semi-automation of forestry cranes : automated trajectory planning and active vibration damping
Sammanfattning : Forests represent one of the biggest terrestrial ecosystems of Earth, that can produce important raw renewable materials such as wood with the help of sun, air and water. To efficiently extract these raw materials, the tree harvesting process is highly mechanized in developed countries, meaning that advanced forestry machines are continuously used to fell, to process and to transport the logs and biomass obtained from the forests.

2. Virtual Holonomic Constraints: from academic to industrial applications
Sammanfattning : Whether it is a car, a mobile phone, or a computer, we are noticing how automation and production with robots plays an important role in the industry of our modern world. We find it in factories, manufacturing products, automotive cruise control, construction equipment, autopilot on airplanes, and countless other industrial applications. LÄS MER
3. Common cranes in agricultural landscapes : linking space use and foraging patterns to conservation and damage prevention
Sammanfattning : Many populations of migratory cranes, geese and swans are increasing throughout Europe and North America. During migration, these birds congregate at staging sites, often located in landscapes with both wetlands and arable land. LÄS MER
4. Fatigue properties of cut and welded high strength steels : Quality aspects in design and production
Sammanfattning : This doctoral thesis concerns fatigue of welded structures. Welding is one of the world’s most common joining methods and it is frequently used in several structural applications in many fields. Some examples are construction vehicles, loader cranes, trucks, busses, forestry and agricultural machines, bridges and ships. LÄS MER
