  1. 1. 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. 2. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields

    University essay from Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysik

    Author : Adi Bijedic; [2021]
    Keywords : ;

    Abstract : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. READ MORE

  4. 3. Magnetic Moment Characterization for Small Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Alejandro Sans Monguiló; [2021]
    Keywords : small satellite; CubeSat; optical magnetic test bed; magnetic dipole moment characterization; residual magnetic moment; permanent magnet verification; magnetic measurement; Foresail-1; Helmholtz cage;

    Abstract : Small satellites are gaining popularity in a wide range of applications where attitude systems require high precision performance. One of the main sources of errors, in case of magnetic attitude control systems, is the residual magnetic moment (RMM) of the spacecraft. READ MORE

  5. 4. Design of column bases concerning bending and shear nibs

    University essay from KTH/Byggteknik och design

    Author : Rodi Kay; [2021]
    Keywords : Column bases; Pelarfötter;

    Abstract : The purpose of the thesis is to find out how to design column bases with conventional methods presented by European standards and codes, but above all from the Steel Construction Institute's handbook on structural joints and compare it with finite element analyses. However, today there are no good instructions for how column bases exposed to multiaxial bending should be designed, where assumptions based on structural mechanics also was compared with computer tools.

  6. 5. Accelerating bulk material property prediction using machine learning potentials for molecular dynamics : predicting physical properties of bulk Aluminium and Silicon

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Nicholas Sepp Löfgren; [2021]
    Keywords : machine learning; moment tensor potential; kernel ridge regression; molecular dynamics; density functional theory; materials science; data-driven materials design; maskininlärning; molekylärdynamik; täthetsfunktionalteori; materialvetenskap; datadriven materialdesign;

    Abstract : In this project machine learning (ML) interatomic potentials are trained and used in molecular dynamics (MD) simulations to predict the physical properties of total energy, mean squared displacement (MSD) and specific heat capacity for systems of bulk Aluminium and Silicon. The interatomic potentials investigated are potentials trained using the ML models kernel ridge regression (KRR) and moment tensor potentials (MTPs). READ MORE
