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

    University essay from Göteborgs universitet/Graduate School

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

    Abstract : 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). READ MORE

  4. 3. Do Stocks Outperform Treasury Bills? Evidence From a Swedish Setting

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Anton Li; Ricky Yu; [2023]
    Keywords : Individual stocks; Treasury bills; Skewness; Buy-and-hold returns; Diversification;

    Abstract : Most Swedish stocks listed since 1983 post lifetime buy-and-hold returns that are less than one-month Swedish Treasury bills. In terms of risk-adjusted returns for the same time horizon, individual Swedish stocks vastly underperform value-weighted benchmarks when measured with a Sharpe ratio. READ MORE

  5. 4. Soil Organic Carbon in Boreal Agricultural Soil : Tillage interruption and its effect on Soil Organic Carbon

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Hilda Alfredsson; [2023]
    Keywords : soil organic carbon; agriculture; tillage interruption; carbon sequestration;

    Abstract : Farmers have been disrupting the carbon cycle ever since humans started converting forests to agricultural lands. But are there farming practices that can be applied to increase the carbon storage in the soil and subsequently counteract increasing carbon dioxide levels in the atmosphere? In this study I investigate if soil organic matter (SOM) and soil organic carbon (SOC) change with longer interruption between tillage events. READ MORE

  6. 5. The pricing accuracy of the unbiased RIV model

    University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Author : Jonny Jin; Daniel Klingberg; [2023]
    Keywords : Pricing accuracy; Residual income valuation; Unbiased accounting; Accounting measurement bias; Conservative accounting;

    Abstract : This paper aims to investigate whether the pricing accuracy of the RIV model is improved with unbiased accounting. The introduction of the Feltham-Ohlson model has left researchers with an eagerness to propose a RIV model with high pricing accuracy. READ MORE
