  1. 1. Effekter av livsmedelsförädling för lokalkorrosion på rostfritt stål 316L

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Fredrik Waldur; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Pitting corrosion on 316L stainless steel has been widely studied, but knowledge is lacking within food processing environments. A new test setup was developed to enable electrochemical measurements inside a heat exchanger (pasteurizer) where solutions can be heated and cooled rapidly, allowing for corrosion tests of solutions that do not withstand high temperatures for a long period of time.

  3. 2. Material Characterization and Blade Impact Simulation

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

    Författare :Gustaf Bodare; [2022]
    Nyckelord :Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Sammanfattning : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. LÄS MER

  4. 3. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Jannek Hansen; [2021]
    Nyckelord :Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Sammanfattning : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. LÄS MER

  5. 4. EYE TRACKING IN USABILITY : A methodology study

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :John Hedlund; [2018]
    Nyckelord :Eye Tracking; Usability Evaluation; Target Search Analysis Framework; Method Development; Test Conditions;

    Sammanfattning : The usability group at RISE Research Institute of Sweden primarily perform usability evaluations for their clients. Usability evaluations are performed on launched products as well as early prototypes, the purpose of these evaluations is to detect problems and give suggestions on how they can be solved. LÄS MER

  7. 5. Structural integrity of dental crowns.

    Magister-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Natalie Hamsund; [2014]
    Nyckelord :;

    Sammanfattning : There is currently no standardized method for testing dentures made of dental ceramic materials. This creates problems for comparisons between studies concerning strength in materials and geometry. The geometry of the maxillary first premolar was used for the analysis. LÄS MER
