  1. 1. Topology optimization: perimeter restriction using total variation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Jonas Fredriksson; [2022]
    Nyckelord :Topology optimization; structural optimization; solid mechanics; total variation; Technology and Engineering;

    Sammanfattning : Topology optimization is a method used to find optimal material distributions, within a specified domain, with respect to some performance measure. To avoid various artifacts to appear in the suggested design, the solution space is typically restricted, where some restriction methods allow different length scales to be controlled in the design.

  3. 2. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Alejandra Fernandez Castaneda; [2022]
    Nyckelord :Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  4. 3. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jakob Andrén; [2021]
    Nyckelord :hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Sammanfattning : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. LÄS MER

  5. 4. Investigations of p-type quantum dots in GaSb nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :In-Pyo Yeo; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. LÄS MER

  7. 5. Förbättrat lagerutnyttjande för köksluckor i centrallager

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Arijan Suljov; Fadi Kawmi; [2020]
    Nyckelord :;

    Sammanfattning : Logistik handlar om att skapa produktiva materialflöden genom att planera, styra och organisera alla aktiviteter i materialflödet, från råvaruköp till produktanvändning. Logistik innefattar många delar av företaget såsom transporter, lager, marknadsföring och ekonomi. LÄS MER
