  1. 11. Modelling Magnetism of hcp Iron under Earth’s Inner Core Conditions : Based on first-principle DFT calculations and Machine Learning

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Linda Le; [2022]
    Keywords : Machine learning; Earth’s Inner Core; hcp Iron; Electronic structure magnetism; Density functional Theory; Local magnetic moments; Ab initio molecular dynamics; ASD-AIMD-MLLSF simulation;

    Abstract : The structure of Earth’s core remains largely a mystery. The solid inner core is believed to exist in extreme pressure and temperature conditions comparable to 300 GPa and 6000 K and consists mainly of iron, Fe. READ MORE

  3. 12. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Jessica Jacobs; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

  4. 13. On the Interaction Between Electromagnetic, Gravitational, and Plasma Related Perturbations on LRS Class II Spacetimes

    University essay from Umeå universitet/Institutionen för fysik

    Author : Philip Semrén; [2021]
    Keywords : ;

    Abstract : In this thesis, we investigate the interaction between electromagnetic, gravitational, and plasma related perturbations on homogeneous and hypersurface orthogonal Locally Rotationally Symmetric (LRS) class II spacetimes. By using these spacetimes, which allow for the inclusion of a non-zero magnetic field, as backgrounds in a perturbative approach, we are able to see interactions between the electromagnetic and gravitational variables already to first order in the perturbations.

  5. 14. Design of current transformer energy harvesting power supply

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Oscar Bäckman; [2021]
    Keywords : Energy harvesting; Current transformer;

    Abstract : This thesis explores the possible method to harvest energy from ambient sources around power transformers. These include magnetic induction and vibration. The objective is to create an energy harvester device that can output enough energy to power multiple sensors, wireless connectivity and an MCU. READ MORE

  6. 15. Investigating the central engine in supernova 2002ap using X-ray observations

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Amanda Helmfrid; Richárd Bagi; [2021]
    Keywords : ;

    Abstract : Supernovae (SNe) are explosions following the death of massive stars. Core-collapse supernovae (CCSNe) occur when the heavy iron core of these stars collapse in on themselves. The resulting remnant of the core of a CCSN is a compact object: either a black hole or a neutron star. READ MORE
