  1. 1. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Þóra Karlsdóttir; [2023]
    Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

    Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

  3. 2. Embedment Behavior of Steel Dowel in Timber Loaded Perpendicular to the Grain : Influence of Assembly History in Combination with Moisture Change and Cyclic Loading

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Mojtaba Khalili; [2023]
    Keywords : Embedment strength; elastic and plastic embedment stiffness; moisture content; swelling and shrinkage; steel dowel; assembly history; cyclic loading;

    Abstract : The embedment behavior of dowels in timber structures, as an essential parameter in the design of connections, is the subject of this thesis. There are numerous advantages using timber structures, including sustainability, energy efficiency, and aesthetic appeal. READ MORE

  4. 3. Development of a computational method for determining gamma energy escape from calorimeters at CLAB

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Amela Mehic; [2022]
    Keywords : Nuclear physics; Calorimeter; SNF; MCNP; Dose rate; CLAB; Gamma energy; Fuel assembly; Form function; Attenuation coefficient; Gamma spectroscopy;

    Abstract : Swedish Nuclear Fuel and Waste Management Company- SKB has conducted measurement campaigns at the Swedish central interim storage facility for spent nuclear fuel- CLAB over the years, extending from year 2003 to 2019 where the gamma energy escape was acquired. At CLAB the spent nuclear fuel assembly is inserted into the calorimeter; device intended to measure temperature increase due to decay heat from the fuel assembly. READ MORE

  5. 4. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    University essay from Linköpings universitet/Fordonssystem

    Author : Gabriel Fredriksson; [2022]
    Keywords : machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Abstract : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. READ MORE

  6. 5. Kulturarvet som medel för platstolkning och platsspecifik utveckling : perspektiv på kulturarvet vid Kustdammarna i Lomma

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)
