  1. 11. Simulation of robot paths and heat effects in welding

    Författare :Mikael Ericsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsteknik; Welding; Automation; robotics; Off-line programming; Robotics; Automatiska system; Production technology; control engineering; Finite Element Analysis; reglerteknik; robotteknik;

    Sammanfattning : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. LÄS MER

    Sammanfattning : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. LÄS MER

  4. 13. Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs

    Författare :Christian Torbrand; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NPWT; negative pressure; vacuum-assisted closure; sternotomy wounds; deep sternal wound infection; mediastinitis; thoracic surgery; pressure transduction; neurohormones; neuropeptides; total heart volume variation; cardiac output; wound contraction; macrodeformation;

    Sammanfattning : Negative pressure wound therapy (NPWT) has been widely adopted for the treatment of deep sternal wound infections due to its excellent clinical outcome. However, the mechanisms of action and effects on hemodynamics have not been thoroughly elucidated. LÄS MER

  5. 14. Robotic Friction Stir Welding for Flexible Production

    Författare :Jeroen De Backer; Gunnar Bolmsjö; Giorgos Nikoleris; Anders Robertsson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding; Automation; Robotics; Aluminium; Lightweight design; Industriell arbetsvetenskap; Industrial engineering; Mechatronics; Mekatronik;

    Sammanfattning : Friction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. LÄS MER

  7. 15. Solar cavity receiver design for a dish-Stirling system

    Författare :Jorge Garrido Gálvez; Björn Laumert; Uwe Gampe; KTH; []
    Nyckelord :Concentrating Solar Power; Solar receiver; Solar simulator; Uncertainty analysis; Monte Carlo ray tracing; Experimental validation; Coatings; System modeling; Structural analysis; Creep damage; Thermal stress; Cavity receiver design; Energy Technology; Energiteknik;

    Sammanfattning : The growing concern for the climate change has led to an increasing research effort in renewable energy technologies in order to achieve a more sustainable electricity production. Concentrating Solar Power (CSP) is identified as a promising technology to deal with part of the future electricity production. LÄS MER
