  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. Analyzing the performance of active learning strategies on machine learning problems

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Vendela Werner; [2023]
    Keywords : computer science; bioinformatics; machine learning; active learning; artificial intelligence; supervised learning; Astrazeneca; maskininlärning; artificiell intelligens; datorvetenskap; active learning; bioinformatik; supervised learning;

    Abstract : Digitalisation within industries is rapidly advancing and data possibilities are growing daily. Machine learning models need a large amount of data that are well-annotated for good performance. To get well-annotated data, an expert is needed, which is expensive, and the annotation itself could be very time-consuming. READ MORE

  4. 3. Analys av lösningsmetoder för stranderosion : fokus på Ystad kommun

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

    Author : Sandra Olsson; [2023]
    Keywords : stranderosion; erosion; erosionsskydd; Ystad kommun; strandfodring; växtbaserade lösningar; stenskoning; vågbrytare; hövdingar;

    Abstract : Stranderosion är ett världsomspännande problem som drabbar kuster och strandsträckor som är betydelsefulla för människan och naturen. Detta i kombination med havsnivåhöjningar, som bidrar till större konsekvenser av erosion, gör det viktigt att kunna hitta inte bara den bästa lösningen på stranderosion utan också den mest miljövänliga.

  5. 4. Glauber Monte Carlo for proton-proton and virtual-photon-proton collisions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Oscar Sepp; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In high energy physics, we want to probe the inner structures and behaviours of the particles that are the building blocks of our universe. This is often done by colliding nuclei together. READ MORE

  6. 5. Changes in Organization Design Produced by Covid-19 from a Path-Dependence Perspective : A Case Study of a Medical Manufacturing Company

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Carolina Artavia Muñoz; [2023]
    Keywords : Organization Design; Black Swan Events; Path Dependence Theory; Jay Galbraith s Star Model; Covid-19; Medical Manufacturing Industry.; Organisationsdesign; svarta svan-händelser; stigberoende; Jay Galbraits Star Model; Covid-19; medicinsk tillverkningsindustri.;

    Abstract : Covid-19 brought various challenges that the world that was not fully prepared to face since 2019. The pandemic came with both health and economic repercussions, and various organizations had to adapt their Organization Design to confront these new challenges posed by this Black Swan event.
