1. Kinematic control of redundant knuckle booms
Abstract : A kinematically redundant four degrees of freedommanipulator arm, a knuckle boom, is studied. Three joints arerevolute and one linear. Since only three degrees of freedomare needed for positioning, we have one redundant degree offreedom. Three different kinematic control strategies arestudied. READ MORE

2. Stiffness and vibration properties of slender tensegrity structures
Abstract : The stiffness and frequency properties of tensegrity structures are functions of the pre-stress, topology, configuration, and axial stiffness of the elements. The tensegrity structures considered are tensegrity booms, tensegrity grids, and tensegrity power lines.A study has been carried out on the pre-stress design. READ MORE

3. Kinematic Control of Redundant Knuckle Booms with Automatic Path Following Functions
Abstract : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. READ MORE

4. Numerical and Experimental Studies of Deployment Dynamics of Space Webs and CubeSat Booms
Abstract : In this thesis, experiments and simulations are performed to study the deployment dynamics of space webs and space booms, focusing on the deployment and stabilization phases of the space web and the behavior of the bi-stable tape spring booms after long-term stowage.The space web, Suaineadh, was launched onboard the sounding rocket REXUS-12 from the Swedish launch base Esrange in Kiruna on 19 March 2012.

5. Mining Booms in Africa and Local Welfare Effects: Labor Markets, Women’s Empowerment and Criminality
Abstract : The role that extractive industries can play in processes of economic development is frequently described as, at best non-existent, or at worst, persistently negative. Extractive industries, while focusing on unearthing large sub-soil wealth, are sometimes linked to adverse political and macroeconomic outcomes in developing countries. READ MORE
