  1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ahsan Ali; [2023]
    Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  3. 2. Representations of Three-Body Interactions In Physics

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Joel Johansen; [2023]
    Nyckelord :Three-Body Interactions; Two-Body Interactions; Physics and Astronomy;

    Sammanfattning : The thesis explores an already developed symmetry adapted representation of a two-body interaction with the main goal of extending the method to also include three-body interactions. The method considers a space of shifted one dimensional Gaussian particle densities which are used, together with their corresponding Hartree potentials, to define the respective collective subspaces in which the interactions are expanded.

  4. 3. Three-body decay as a baryon polarizer

    Kandidat-uppsats, Uppsala universitet/Kärnfysik

    Författare :Carl Johan Königsson; [2023]
    Nyckelord :Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

    Sammanfattning : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. LÄS MER

  5. 4. Body weight, body condition and structural size of Scandinavian wolves

    Master-uppsats, SLU/Dept. of Ecology

    Författare :My Strömgren; [2023]
    Nyckelord :age; Canis lupus; food availability; inbreeding; natal territory; season; sex; wolf density;

    Sammanfattning : Large carnivours are suffering from population declines all over the world, but many have also recolonized parts of their previous habitats. However, recovery by these species is usually slow and challenging. LÄS MER

  7. 5. The effect of body position on the relative contribution of the rib cage to speech breathing and voice quality

    Kandidat-uppsats, Stockholms universitet/Avdelningen för fonetik

    Författare :Helena Engström; [2023]
    Nyckelord :Speech breathing; body position; voice quality; respiratory inductance plethysmography; accelerometer; Talandning; kroppsposition; röstkvalité; respiratory inductance plethysmography; accelerometer;

    Sammanfattning : This study investigates how body position affects the relative contribution of the rib cage to speech breathing and voice quality. The frequently used upright and supine body positions are expanded with the addition of an inverted position as a condition. LÄS MER
