  1. 11. Developing a drill boom attachment to extract iron ore in a new mining system

    University essay from Karlstads universitet

    Author : Niklas Berntsson; [2021]
    Keywords : ;

    Abstract : The modern product development technique led this bachelor thesis forward with structure and finesse by using the Double Diamond theory. The bachelor thesis was carried out in collaboration with LKAB and NECAB with the aim of develop and design a two-parted mechanical attachment for their new mining system. READ MORE

  3. 12. Power and Electronics in Autonomous Glider for Sounding Rocket Experiments

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexander Malmberg; Oskar Munter; [2021]
    Keywords : Servos for space; Low temperature batteries; Position sensor; REXUS BEXUS;

    Abstract : The aim of this bachelor’s thesis is to design theelectronics for an autonomous glider to be used in a soundingrocket experiment with return to launch site functionality. Theelectronics includes a battery solution, servos and a hardwareplatform for communication and control software. READ MORE

  4. 13. Simulation of Collaborating Autonomous Gliders

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kajsa Buckard; Oscar Meyer; [2020]
    Keywords : ;

    Abstract : Drones today have a wide field of application, for example monitoring vast areas and pollination of fruit trees in Japan. Even though drones can do many different types of services today, they are still limited to power usage which results in that drones are not able to stay aloft for a very long time. READ MORE

  5. 14. Large Surveys and Data-Driven Investigations of Radial Migration

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : John Bradley Bowers; [2019]
    Keywords : Physics and Astronomy;

    Abstract : We probe the implications of 5 different previously developed models of the evolution of the Milky Way’s radial metallicity gradient for radial migration of stars observed today between 5kpc < R < 12kpc. Our sample contains 7167 giant stars, with metallicities and radial velocities obtained from APOGEE DR14, full 5-parameter kinematic information from Gaia DR2, and ages derived in Martig et al.

  6. 15. The Dissipating Energy Flow method for analysing generator contribution to power system damping -- evaluation and interpretation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Hampus Möller; [2019]
    Keywords : Electromechanical oscillations; small-signal stability; energy flow; PMU measurements; forced oscillations; dissipating energy.; Technology and Engineering;

    Abstract : Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. READ MORE
