  1. 1. The visibility of stellar transients in the Galactic Centre

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

    Författare :Jonathan Ström; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. LÄS MER

  3. 2. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

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

    Författare :Yoana Ilarionova; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. LÄS MER

  4. 3. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Fabian Sondh; Erik Hansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER

  5. 4. Plastic deformation of hot riveted joints acting in shear

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Victor Gard; [2023]
    Nyckelord :;

    Sammanfattning : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. LÄS MER

  7. 5. Numerical analysis of a bearing strength in delaminated composite joint

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Olavi Kukkonen; [2023]
    Nyckelord :Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Sammanfattning : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.
