  1. 6. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mhd Osman Bernieh; [2023]
    Nyckelord :Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Sammanfattning : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. LÄS MER

  3. 7. Exploring the industrial packaging of components for complex electrical products and its sustainability and circularity

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Tirouvaasavy Tirougnanassambandamourty; Felix Strömberg; nil nil; nil nil; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master’s thesis explores the sustainability and the circularity of industrial packaging of components for complex electronic products. The research aims to gain insight into the structure of the packaging system between the suppliers and the manufacturers (EMS) and evaluate its circularity to identify the opportunities and challenges for future improvement.

  4. 8. The Impact of Swampland Conjectures

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Daniel Nilsson; [2023]
    Nyckelord :String theory; Quantum gravity; Swampland program; Effective field theories;

    Sammanfattning : The Swampland program is way of sorting effective field theories based on conjectures of how an effective field theory consistent with quantum gravity should look like. In this thesis we take a closer look at the No Global Symmetries Conjecture, the Weak Gravity Conjecture, the de Sitter Conjecture and the Trans-Planckian Censorship Conjecture. LÄS MER

  5. 9. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Nyckelord :Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Sammanfattning : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. LÄS MER

  7. 10. Navigating the Storm: An examination of IPO Underpricing in 21st Century Crises

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Douglas Otterström; Rebecca Byström; [2023]
    Nyckelord :Initial public offering; IPO; IPO underpricing; Financial Crisis;

    Sammanfattning : IPO underpricing is a phenomenon studied by many, with theories explaining the reason for this mispricing problem. However, there is little to no research examining how IPO underpricing reacts to different crises during the 21st century. This paper focuses on companies issuing in the US market on NYSE and NASDAQ.
