  1. 21. The Quantum Hall Effect

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Conrad Grälls; [2020]
    Keywords : quantum hall effect; QHE; fractional quantum hall effect; FQHE; hall effect;

    Abstract : The quantum Hall effect occurs when a conductor carrying a current is placed in a perpendicular magnetic field. If certain conditions are met, such as strong magnetic field and low temperature, the resistivity becomes quantised, taking values of integer or fractional multiples of h/e2. READ MORE

  3. 22. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Simon Wozny; [2020]
    Keywords : topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

    Abstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE

  4. 23. Electric Load Driven Longboard

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JOHAN ANDERSSON; RICKARD HÖGLUND; [2020]
    Keywords : mechatronics; longboard; brushless direct current motor; Hall effect sensor; load cell; Wheatstone bridge; LiPo battery; Arduino; ODrive; mekatronik; longboard; borstös likströmsmotor; Hall effekt sensor; lastcell; Wheatstone brygga; LiPo batteri; Arduino; ODrive;

    Abstract : This bachelor’s thesis aims to show an extensive overview of all the parts that build up an electric load driven longboard and see if a load controlled longboard can be seen as a safe, comfortable and convenient alternative to the more common remote controlled longboard. The thesis will also answer how weight can be measured on a longboard in the most effective way, what the most comfortable riding technique is and what a good motor-battery configuration to be able to travel at 30 km/h and 10 km would be.

  5. 24. Image Analysis Methods For Additive Manufacturing Applications

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Jayanth Ramakrishna Yogendra; [2020]
    Keywords : Additive Manufacturing; Image Analysis; ImageJ; MIPAR; Superalloys;

    Abstract : There is an upsurge of research interest on Ni-based superalloys additively manufactured (AM) in aerospace sectors. However, achieving the accuracy and quality of the AM part is a challenging task because it is a process of adding material layer by layer with different process parameters. READ MORE

  6. 25. A Xenon Collisional Radiative Model for Electric Propulsion Application : Determining the electron temperature in a Halleffect Thruster

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

    Author : Tarek Ben Slimane; [2020]
    Keywords : ;

    Abstract : Hall effect thrusters (HET) that rely on xenon as a propellant are widely adoptedtoday for their efficiency. To understand the kinetics of the xenon plasma dischargein the thruster, we developed a collisional radiative model for xenoninspired by the work of Karabadzhak et al. [1]. READ MORE
