  1. 1. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Marcus Westlund; [2019]
    Nyckelord :bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Sammanfattning : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. LÄS MER

  2. 2. Takinfästningar mot KL-trä- eller stålregelstomme

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Mohamad Khodabakhsh; [2019]
    Nyckelord :;

    Sammanfattning : The study includes the complementation of CLT- or steel joist frames with wooden joists. The wooden bars are meant to be a link, a waler between different types of wall frames and roof elements. This study has been conducted in collaboration with the company Lättelement AB. LÄS MER

  3. 3. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Joel Johansson Byberg; [2019]
    Nyckelord :CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Sammanfattning : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

  4. 4. Investigation of jets in the magnetosheath using Cluster measurements

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Annam Tanveer; [2019]
    Nyckelord :;

    Sammanfattning : With the help of the measurements made by Cluster spacecrafts, an investigation of fast plasma flowcalled jets in the magnetosheath has been made. The investigation covers a large statistical study ofjets with two definitions of jets and therefore two different approaches to detect jets.The study has been divided into three parts. LÄS MER

  5. 5. On the roles of schooling, colour and body size for thermoregulatory capacity in aquatic ectotherms

    Master-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Alexandra Karatza; [2019]
    Nyckelord :;

    Sammanfattning : For ectothermic organisms, both terrestrial and aquatic, the environmental temperature is imperative for their metabolic processes and finally for their growth and fitness. Previous research have shown that aquatic ectothermic organisms through the process of sun basking, were able to increase their body temperature in comparison with the one of the surrounding water.
