  4. 2. Kinematic control of redundant knuckle booms

    Author : Björn Löfgren; KTH; []
    Keywords : manipulator; kinematic control. Redundant;

    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

    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

  7. 5. Water supply in hard rock coastal regions : The effect of heterogeneity and kinematic porosity

    Author : Robert Earon; Bo Olofsson; Gerhard Barmen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coastal aquifer; Crystalline rock; Water balance; Geographic information systems; Water supply planning;

    Abstract : Water resources in hard rock terrain are difficult to characterize due to heterogeneity and anisotropy in the fracture network, low porosities and limited recharge volumes available during the summer season. Three methods were developed and evaluated in order to assist in water supply planning. READ MORE
