  1. 21. Tactile Grasping for Domestic Service Robots : Simulations, Experiments and Hand Design

    Författare :Johan Tegin; Jan Wikander; Rüdinger Dillman; KTH; []
    Nyckelord :Manipulators; Simulation; Robot tactile systems; Modeling; Grasping; Tactile sensors; Mechanical engineering; Maskinteknik;

    Sammanfattning : This thesis presents methods and tools for robotic grasping. The application in mind is service robots for a home environment, although the work also has applications in other areas. Service robots must be capable of manipulation, i.e. LÄS MER

  3. 22. In-Plane Fracture of Paper

    Författare :Johan Tryding; Institutionen för byggvetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Paper; Fracture energy; Strain softening; Localized damage; Fracture mechanics;

    Sammanfattning : The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. LÄS MER

  4. 23. Adaptive Grasping Using Tactile Sensing

    Författare :Emil Hyttinen; Danica Kragic; Renaud Detry; Giacomo Spampinato; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Grasping; Tactile Sensing; Computer Science; Datalogi;

    Sammanfattning : Grasping novel objects is challenging because of incomplete object data and because of uncertainties inherent in real world applications. To robustly perform grasps on previously unseen objects, feedback from touch is essential. In our research, we study how information from touch sensors can be used to improve grasping novel objects.

  5. 24. Process-Induced Local Material Variations in Finite Element Simulations of Cast and Fibre Reinforced Injection Moulded Components

    Författare :Johan Jansson; Kent Salomonsson; Jakob Olofsson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The purpose of this thesis is to provide an overview of the methods used in the appended papers, in order to consider heterogeneous material properties in finite element simulations by using process simulations as input. The work deals with both injection moulded and cast components, and focuses on process-induced local material variations and their effect on component performance. LÄS MER

  7. 25. Potential impact of climate change on European agriculture: a case study of potato and Colorado potato beetle

    Författare :Bakhtiyor Pulatov; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colorado potato beetle; climate change; day length; degree day model; frost damage; distribution; temperature; potato; regional climate model; synchrony;

    Sammanfattning : European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. LÄS MER
