  1. 1. Hellre en trygg hamn än ett stormigt hav : En kvantitativ studie om safe havens på den svenska aktiemarknaden under perioder av kris

    Kandidat-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Patricia Johansson; Jonathan Wessman; [2022]
    Nyckelord :Business economics; financial economics; safe haven; risk; crisis; Företagsekonomi; finansiell ekonomi; safe haven; risk; kris;

    Sammanfattning : Denna studie undersöker fem olika tillgångar under tre olika kriser för att se vilka tillgångar som kan definieras som en safe haven på den svenska aktiemarknaden. Tillgångarna som undersöks är guld, 10-årig statsobligation, japansk yen, schweizisk franc och amerikansk dollar. LÄS MER

  3. 2. Bubble Dynamics on Artificial Nucleation Sites in Boiling Heat Transfer

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

    Författare :Yuqing Zhang; [2021]
    Nyckelord :;

    Sammanfattning : Pool boiling heat transfer is a complicated scientific problem due to the complex phase change process. In recent years, with the development of nuclear technology, microelectronics and space exploration, more attention has been paid to boiling which present great potentials for the thermal management in these applications because nucleate boiling has much better heat transfer performance than single-phase fluid, while bubbles, including their departure frequency and diameter and the interaction between bubbles plays an important role in determination of the heat transfer performance.

  4. 3. Bubblan som sprack - Isabella Löwengrips kriskommunikation genom bloggen

    Kandidat-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaper

    Författare :Emelie Sandberg Fransson; Petra Olgarsson; [2020]
    Nyckelord :Isabella Löwengrip; Image Repair Theory; Self-Presentation Theory; rhetoric textual analysis; crisis communication;

    Sammanfattning : The research conducted in The Bubble That Burst – Isabella Löwengrip’s Crisis Communication Through Blog Posts aims to answer how Isabella Löwengrip attempted to save both her and her companies images during a crisis in the fall of 2019. Benoit’s Image Repair Theory and Goffman’s Self-Presentation Theory were combined to create the framework of this study. LÄS MER

  5. 4. Relativistic attosecond electron pulses by laser wakefield acceleration

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

    Författare :Cornelia Gustafsson; [2020]
    Nyckelord :laser wakefield accelerator; laser wakefield acceleration; attosecond; electron pulses; Physics and Astronomy;

    Sammanfattning : The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained.

  7. 5. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Daiki Makii; [2020]
    Nyckelord :Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

    Sammanfattning : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far. LÄS MER
