  1. 1. Particle Simulation using Asynchronous Compute : A Study of The Hardware

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Kim Enarsson; [2020]
    Nyckelord :Asynchronous Compute; Particle Simulation; Multi-Engine; DirectX; Async Compute; Asynchronous Compute; Partikel Simulering; Multi-Engine; DirectX; Async Compute;

    Sammanfattning : Background. With the introduction of the compute shader, followed by the application programming interface (API) DirectX 12, the modern GPU is now going through a transformation. Previously the GPU was used as a massive computational tool for running a single task at unparalleled speed. LÄS MER

  2. 2. Capture of interstellar objects in the Solar system

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Jonathan Petersson; [2020]
    Nyckelord :interstellar objects; Physics and Astronomy;

    Sammanfattning : Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. LÄS MER

  3. 3. B-plane orbital resonance analysis and applications

    Master-uppsats, KTH/Rymdteknik

    Författare :Alessandro Masat; [2020]
    Nyckelord :;

    Sammanfattning : Many space engineering and orbital mechanics applications seek for the usage of focused mathematical models, capable of providing useful insight onto particular phenomena or exploiting some theoretical and physical tools to reduce the computational costs and/or increase the level of accuracy reached. Orbital resonances are one of the phenomena that needs to be properly modelled, both for exploiting such features in the mission design phase and to predict possible resonant returns of threatening objects closely approaching a specified planet.

  4. 4. Do variations in the initial mass function affect galaxy evolution?

    Master-uppsats, Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Författare :Mateo Prgomet; [2020]
    Nyckelord :galaxy; galaxy formation; galaxy evolution; feedback; star formation; ultra faint dwarf galaxy; initial mass function; variations; universe; redshift; hydrodynamics; cosmology; zoomed-in simulations Galaxy formation and evolution; galaxy feedback; stellar feedback; IMF variations; cosmological zoomed-in simulations; Physics and Astronomy;

    Sammanfattning : The initial mass function (IMF) describes the stellar mass distribution for a population of stars at birth. This parameter represents a topic of long standing discussion within astronomy due to its apparent insensitive nature to environmental conditions. However, in the last decade, significant evidence suggesting the contrary has been presented. LÄS MER

  5. 5. How Stellar Tides Affect Planet Evolution

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Madison Green; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Planets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. LÄS MER
