  1. 1. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Peter Dagbui; [2023]
    Keywords : Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Abstract : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. READ MORE

  3. 2. Effects of power-law correlated disorder on a 3D XY model

    University essay from KTH/Fysik

    Author : Philip Broms; [2022]
    Keywords : Condensed matter physics; Ising model; XY model; Markov Chain Monte Carlo; Phase transition; Disorder; Theoretical physics; Wolff algorithm; Kondenserade materians teori; Isingmodell; XY-modell; Markovkedje-Monte Carlo-metoder; Teoretisk fysik; Oordning; Fasövergångar; Wolffalgoritmen;

    Abstract : This thesis investigates the effects of power-law correlated disorder on a three-dimensional XY model and the Weinrib-Halperin disorder relevance criterion’s pre-dictive ability. Ising models are used as a map to realise disorder couplings. READ MORE

  4. 3. Low-dimensional Magnetism in Novel 2D Honeycomb Materials

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Johnsen; [2021]
    Keywords : Applied physics; Materials physics; Quantum materials; Magnetism; Muons; Neutrons; Tillämpad fysik; Materialfysik; Kvantmaterial; Magnetism; Myoner; Neutroner;

    Abstract : A Kitaev quantum spin liquid is a phase of matter predicted to host excitations that can be used to preform fault-tolerant quantum computation. Though the theoretical prediction of such a state is on firm footing, its realisation in real materials has proven to be elusive. READ MORE

  5. 4. Thermodynamical properties of cellular automata

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Luca Bertolani; [2020]
    Keywords : Thermodynamics; Statistical; Mechanics; Cellular; automata; chaos; complex; matrix; computational; mathematical; 2d; two; dimensional; program; code; python; ising; teaching; ideal; gas; partition; function; equilibrium; non-equilibrium; classification; neighbourhood; local; Physics and Astronomy;

    Abstract : Cellular automata are a set of discrete computational models whose evolution is defined by neighbourhood rules and are used to simulate many complex systems in physics and science. In this work, statistical mechanics and thermodynamics in and out of equilibrium are used to develop a five-class classification scheme for two-dimensional cellular automata. READ MORE

  6. 5. Implementation of an Automatic Voltage Regulator for Synchronous Machines on an FPGA

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Eric Fjärstedt; [2019]
    Keywords : hydro power; synchronous machine; magnetisation; LabVIEW; FPGA;

    Abstract : Synchronous generators used for hydro power and nuclear power is a well known topology but there is a vast amount of intricate technologies and methods to making them function properly. This masters thesis covers the development, implementation and verification of a magnetisation system for a synchronous generator. READ MORE
