  2. 1. 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

  4. 2. Development of Novel In Situ Microscopy Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental scanning electron microscopy; polymer film; manipulator; yeast cell; swelling; in situ; water transport; cellulose fibre; osmotic shock; water interaction;

    Abstract : The transport of water in soft materials can occur in liquid or gas phase and is highly dependent on the material microstructure and the structure dynamics. Understanding these relationships is the basis for the development of predictive models that can aid the design of new and improved functional materials. READ MORE

  5. 3. Design of Optimal Control Processes for Closed-Loop Chain SCARA-Like Robots

    Author : Mathias R Lidberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unpowered actuator.; SCARA-robot; closed-loop chain; manipulator;

    Abstract : The design of optimal control processes for closed-loop chain SCARA-like robots is the subject of this thesis. In comparison with the well-known SCARA robot, the proposed new structure is characterized by the incorporation of an additional powered actuator, several unpoweredactuators and an additional link that gives a closed-loop chain robot.

  6. 4. Development of Novel In Situ ESEM Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental scanning electron microscopy; cellulose fibre; water transport; swelling; osmotic shock; yeast cell; in situ; manipulator; water interaction;

    Abstract : The transport of water is central to many applications of soft biomaterials; for example water management in personal care products, controlled drug release in pharmaceuticals and, on a fundamental level, the activities of living cells. Water transport through a material may occur in both liquid and gas phase, and is highly dependent on the microstructure. READ MORE

  7. 5. Streptococcus pyogenes - a manipulator of human defences

    Author : Fredrik Kahn; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; M protein; neutrophils; platelets; platelet-neutrophil complexes; fibrinogen; IgG; abscess; venous thrombosis; heparin binding protein; thrombocytopenia;

    Abstract : Streptococcus pyogenes is a major human pathogen with more than 500 000 casualties annually of which at least 163 000 are due to invasive infections. The remainder is due to post-streptococcal complications with rheu¬matic heart disease constituting the majority. S. READ MORE
