  1. 1. Hybrid Rendering in 3D Map-Based Grand Strategy Games

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

    Författare :Kajsa Buckard; [2022]
    Nyckelord :Computer graphis; ray tracing; rasterization; strategy games; Datorgrafik; strålspårning; rastrering; strategispel;

    Sammanfattning : Ray tracing comes together with a tremendous computational cost [1]. Therefore, Keller et al., expressed that possible cost reduction appears when a hybrid rendering pipeline is implemented by combining rasterization and ray tracing, which have already been introduced to the film and game industries.

  3. 2. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Gaurav Senthil Kumar; [2022]
    Nyckelord :QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Sammanfattning : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. LÄS MER

  4. 3. Simulation of birefringence effects for high-energy neutrino detectors

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2021]
    Nyckelord :astroparticle physics; radio detection; high-energy neutrinos; birefringence;

    Sammanfattning : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. LÄS MER

  5. 4. Wireless wave propagation in city street canyons

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Andrés Felipe Garcia Albarracin; [2017]
    Nyckelord :Channel modeling; Channel sounding; Local scattering function; Ray tracing.; Technology and Engineering;

    Sammanfattning : This project aims to determine the characteristics of a wireless communication channel in city-street-canyon scenarios. The channel of a typical city intersection is modeled with a ray tracer and measured with a channel sounder. Then, the results of both tools are compared in terms of the local scattering function.

  7. 5. Influence of Sample Preparation on Portable XRF-analyses of Aeolian Sediments: a Case Study

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Markus L. Fiola; [2017]
    Nyckelord :portable XRF; loess; sediment; bärbar XRF; lössjord; sediment;

    Sammanfattning : The geochemical composition of aeolian sediments like windblown dust particles is of major importance for the exploration of dust origin and weathering conditions. This allows for the reconstruction of dust transport pathways and thus wind directions and palaeoclimate conditions. LÄS MER
