  1. 6. Analysis and Design of a Microgravity Drop Tower

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Tristan Edwards; [2023]
    Keywords : drop tower; microgravity;

    Abstract : A drop tower is a device that produces a microgravity environment by allowing an experiment to free fall for a short period of time, usually less than 10 seconds. Certain types of drop towers are also capable of reproducing the gravitational conditions of other celestial bodies, such as Lunar and Martian gravity. READ MORE

  2. 7. Ab inito calculation of the formation energy of the sigma phases at 1000 Kelvin : With a five sublattice model for the ternary Iron-Chromium-Nickel system

    University essay from KTH/Materialvetenskap

    Author : Fabian Mathias Veid; [2022]
    Keywords : ;

    Abstract : This project investigates the σ-phase formation energy at 1000 Kelvin using Exact Muffin TIn Orbital (EMTO) method and considers the disordered local moment approach to handle the paramagnetism in a self-consistent manner. The sigma phase is detrimental and causes embrittlement when it occurs primarily in stainless steel and superalloys with Iron (Fe) and Chromium (Cr), which is why it is necessary to understand it better and therefore avoid it.

  3. 8. Centennial Climate Variability

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Thomas Askjær; [2022]
    Keywords : Climate variability; paleoclimate; climatemodelsimulations; proxyrecords; spectralanalysis; model proxycomparison;

    Abstract : Throughout earths history, the climate have always naturally varied due to both external forcings and internal mechanisms. With the outlook on future climate change, it is important to understand the climate system and this includes its natural variability. Depending on the driving mechanisms, the variability happens over different timescales. READ MORE

  4. 9. Colliding Galaxies in a (Nut)Shell

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Jonathan Petersson; [2022]
    Keywords : shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

    Abstract : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

  5. 10. Planes of satellite galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jessica Laura Erika Kocher; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. READ MORE
