1. 11. The Ratio of Reality : A study of the gyromagnetic ratio in theories ranging from classical mechanics to string theory

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Daniel Nilsson; [2021]
   Nyckelord : Quantum field theory ; String theory ; Dirac equation ; Dirac theory ; Dirac; gyromagnetic; ratio; g-factor; Kvantfältsteori; strängteori; Dirac; g-factor; gyrmagnetisk kvot ;

   Sammanfattning : In this project a theoretical study of the so called gyromagnetic ratio was done by investigating classical mechanics, Dirac theory and string theory. The gyromagnetic ratio is a constant term appearing in the coupling between angular momentum and magnetic moment for a particle. LÄS MER

3. 12. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Calle Stenberg; [2021]
   Nyckelord :double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

   Sammanfattning : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.

4. 13. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Malin Strandberg; [2021]
   Nyckelord :Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

   Sammanfattning : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

5. 14. Energy-efficient Industrial processes : An investigation in the power consumption, power number, thrust force and torque requirement on a rotating bed reactor

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Kasim Ali Haji; [2021]
   Nyckelord :RBR Simulation; CFD models of an RBR; Energy-efficient Industrial processes; Power number; Power consumption; RBR; rotating bed reactor; Experimental and simulation of an RBR; Empirical models of an RBR; Thrust force; Torque requirement; k-epsilon model of an RBR; SST k-omega model of an RBR.;

   Sammanfattning : Rotating bed reactors are used throughout the process industry. They are usedboth in the chemical industry and other industrial sectors, such as pharmaceuticals and the textile industry in decolorization due to by-products or contaminants.SpinChem AB manufactures rotary bed reactors (RBRs) to perform chemical reactions between liquids and solids.

7. 15. Excitation system – simulation, tuning and evaluation

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Philip von Heideken; [2021]
   Nyckelord :;

   Sammanfattning : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.
