  1. 1. En teoretisk modell för 3D-printing av fälg i kolfiber

    M1-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Samuel Hall; [2022]
    Nyckelord :3D-printing; Carbon fiber; Carrim; Automotive wheels;

    Sammanfattning : The automotive industry faces the challenge to manufacture vehicles with reduced material usage and climate impact. To achieve this the industry has begun using other materials such as carbon fibre composite than materials such as steel and aluminium which are normally used for the manufacturing of automobile parts.

  3. 2. Fibres from agricultural hemp waste

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Ella Kärkkäinen; Åsa Älgbrant; Simon Kronberg; [2021]
    Nyckelord :Hemp fibres; hemp residue; unretted hemp; nonwoven hemp;

    Sammanfattning : There is an increasing demand for natural fibres in the textile industry as a consequence of the negative impact of the industry on the environment. Svensk Hampaindustri (SHI) is currently growing hemp in Sweden for its seeds. This leaves residue in the form of hemp stems that could be processed for textile products. 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. Shear stiffness of cross laminated timber diaphragms - A study of the influence of connection and member stiffness

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

    Författare :Gustaf Olausson; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Since ancient times, buildings have been constructed with the use of timber and during the modern era, new types of timber products have been developed. Today, more constructions, especially residential buildings are being built with timber as the main load-bearing material. LÄS MER

  7. 5. Test setup for LDMX HCal readout

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Joshua Greaves; [2020]
    Nyckelord :Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Sammanfattning : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.
