  1. 1. A practical approach to cooperative aerial transportation of a load by UAVs

    Master-uppsats, KTH/Reglerteknik

    Författare :Spyridon Papasideris; [2017]
    Nyckelord :;

    Sammanfattning : A path following controller for a system, composed of a single cylindrical load and connected totwo unmanned aerial vehicles by two cables, is designed. The load is modeled as a uniformlydistributed mass while the aerial vehicles are assumed to be fully actuated point masses. Theinputs to the UAVs-load system are the 3D force inputs of each UAV.

  3. 2. Kinematic Robot Calibration Using a Double Ball-Bar

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Sandra Collin; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Calibration of robots is an essential part of industry today when there is a high accuracy requirement. Several calibration methods have proven to be highly accurate but also expensive and time consuming to use. In this thesis a new calibration method has been developed. LÄS MER

  4. 3. Optimization of Electromechanical Slip Ring

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Niklas Hallberg; Jonas Bergström; [2016]
    Nyckelord :Mechatronics; Slip Ring; Product Development; Technology and Engineering;

    Sammanfattning : Today's network cameras are constantly evolving, giving us higher resolution and higher quality video streams which demands higher capacity data links. In Pan, Tilt, Zoom (rotating) cameras the Slip Ring acts as the single communication link between the stationary and rotating parts of the camera and at the same time enables unrestricted rotation.

  5. 4. Offset modeling of shell elements : A study in shell element modeling using Nastran

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :David Klarholm; [2016]
    Nyckelord :Offset shell elements; finite element; Nastran; shell element modeling; Rigid body connection; Rigid links; Kirchhoff shells; Multipoint constraint;

    Sammanfattning : At Saab Aerostructures they are manufacturing a lot of parts for Airbus and Boeing. When these components are investigated using finite element analysis four-node Kirchhoff shell elements and a very fine mesh is often used. LÄS MER

  7. 5. Swedish Foreign Direct Investments in Countries Transitioning into Stabilisation

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Kristina Johansson; Marie Liljegren; Luisa Menjivar; [2009]
    Nyckelord :FDI; OLI-framework; Horizontal FDI; Vertical FDI; SAA; Serbia; Market-seeking; Resource-seeking; Efficiency-seeking; Management of enterprises; Företagsledning; management; Business and Economics;

    Sammanfattning : The purpose of this thesis is to describe and analyse how and why Swedish companies choose to enter a country transitioning into stabilisation. With a qualitative, abductive approach the thesis aims at an analytical generalisation. The explorative nature of the paper is made with a multi-case study. The empirical data was generated by interviews. LÄS MER
