  1. 1. Polarizability and Orientation Dynamics of Small Proteins

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Ebba Koerfer; [2022]
    Nyckelord :Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Sammanfattning : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. LÄS MER

  3. 2. Structural Dynamics at Higher Frequencies using the Finite Element Method : Assessment of Solver Algorithms and Component Mode Synthesis for Dynamic Response Analysis of Large Structures

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Khashaiar Noushin; [2022]
    Nyckelord :;

    Sammanfattning : Scania is making a transition from traditional combustion engines to electric vehicles and therefore developing methodology for high frequency analysis of large structures. The computational time size of results files are impractically high, making any analysis infeasible. LÄS MER

  4. 3. A bonded discrete element approach to simulate loading with hydraulic mining excavators

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

    Författare :Carl Andersson; [2021]
    Nyckelord :DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

    Sammanfattning : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. LÄS MER

  5. 4. Physics-Based, Real-Time Simulation of Fluid-Immersed Rigid Bodies

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Filip Moreau; [2021]
    Nyckelord :Correctness; Fluid; Hydrodynamics; Physics-Based; Physics; Real-Time; Rigid Body Dynamics; Simulation; Virtual Environment;

    Sammanfattning : Objects interacting with fluid are of high interest to visually present in three-dimensional applications, such as computer games and virtual environments. For presenting the interactions with high correctness, dynamic rigid body simulation may be used. LÄS MER

  7. 5. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Sohail Anwar; [2020]
    Nyckelord :Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Sammanfattning : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). LÄS MER
