  1. 1. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity

    University essay from KTH/Fysik

    Author : Atabak Fathe Jalali; [2024]
    Keywords : Theoretical physics; astrophysics; modified gravity; minimally modified gravity; gravitational collapse; VCDM; scalar collapse; apparent horizon; numerical relativity; Teoretisk fysik; astrofysik; modifierad gravitation; minimalt modifierad gravitation; gravitationskollaps; VCDM; skalär kollaps; uppenbar horisont; numerisk relativitet;

    Abstract : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. READ MORE

  3. 2. Planet-NeRF : Neural Radiance Fields for 3D Reconstruction on Satellite Imagery in Season Changing Environments

    University essay from Linköpings universitet/Datorseende

    Author : Erica Ingerstad; Liv Kåreborn; [2024]
    Keywords : NeRF; Neural Radiance Field; Satellite Imagery; Machine Learning; Deep Learning;

    Abstract : This thesis investigates the seasonal predictive capabilities of Neural Radiance Fields (NeRF) applied to satellite images. Focusing on the utilization of satellite data, the study explores how Sat-NeRF, a novel approach in computer vision, per- forms in predicting seasonal variations across different months. READ MORE

  4. 3. ‘NOTHING IS IN VAIN': Non-Standard Negation and Cyclical Change in Kutu, Kwere, and Zalamo

    University essay from Göteborgs universitet/Institutionen för språk och litteraturer

    Author : Aron Zahran; [2023-10-31]
    Keywords : Engelska; Bantu; Morphosyntax; Historical Linguistics; Grammaticalization; Descriptive Linguistics; Typology; Negation; Possessive Predication; Locational Predication; Negative Existentials; Semantic Change;

    Abstract : This work concerns the polyfunctionality and grammaticalization of an item bule in the under described Tanzanian Bantu languages, Kutu, Kwere, and Zalamo. Through collection and analysis of field data, it is shown that the original adverbial element bule ‘for free, in vain, for no reason’ has developed a wide range of functions within the domain of non-standard negation.
