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

    Master-uppsats, KTH/Fysik

    Författare :Atabak Fathe Jalali; [2024]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Demand Forecasting of Automobile Spare Parts after the End-of-Production - A review of demand forecasting models

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Abid Ali; Arosha Ratnayake; [2023-07-03]
    Nyckelord :Demand forecasting; Spare parts; Automobile; End-of-Production EOP ; PRISMA; AHP; MCDM;

    Sammanfattning : Demand forecasting of spare parts plays a crucial role in automobile industry where it generally requires a significant attention in controlling inventory. It is possible to maintain an optimal stock level when there is a continues supply at the Original Equipment Manufacturers (OEMs). LÄS MER

  4. 3. The Greenfee of Beta - Unraveling the Impact of Sustainability on Systematic Risk

    Kandidat-uppsats,

    Författare :Johannes Sigurdson; Chris Teow; [2023-06-30]
    Nyckelord :;

    Sammanfattning : This paper unravels the impact of sustainability on systematic risk. Literature suggests that enhanced sustainability reduces companies' systematic risk, thanks to e.g. product differentiation, a broader spectrum of investors holding the assets, or simply because there exists a specific ESG factor.

  5. 4. Do you want to swap? A study of the liquidity risk in the SEK interest rate swap market

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Viktor Edberg; Carl Hjelmqvist; [2023-06-29]
    Nyckelord :Bao; Pan; Wang indicator; Determinants; Dimensions of liquidity; Forward Rate Agreement; Fundamental Review of the Trading Book; Generalized least squares; Interest Rate Derivative; Interest Rate Swap; Liquidity horizon; Liquidity risk premium; Market liquidity; SVEN spread; Swap Spread; Swedish Government benchmark bond; Treasury-Eurodollar; Turnover ratio; Turnover-per-day; Volume-adjusted intraday volatility;

    Sammanfattning : Interest rate swaps are one of the world’s most essential interest rate derivatives. It is therefore important to understand the pricing of these agreements, and how the market is functioning. LÄS MER

  7. 5. EU-KOMMISSIONENS MISSION – VÄGEN TILL KLIMATNEUTRALITET FÖR EUROPAS STÄDER

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Clara Forsman; [2023-03-23]
    Nyckelord :Viable Cities-programmet; missionen; hållbarhetsarbete; styrningsmentalitet; klimat; medborgarinkludering; styrning; makt;

    Sammanfattning : To tackle the challenges posed by climate change in cities, the European Commission has launched a new initiative within Horizon Europe, the Mission for Climate Neutral and Smart Cities. The 100 chosen cities in the mission will work to become climate neutral by 2030, 20 years before the rest of the EU. LÄS MER
