  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

This research examines the current challenges and provides alternative solutions for better password management. This study encompasses a comprehensive survey and interviews conducted with individuals across various professional backgrounds. LÄS MER

  4. 3. Performance impacts when moving from a VM-based solution to a container-based solution

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Nicklas Muchow; Danial Amir Jalali; [2022]
    Nyckelord :;

    Sammanfattning : Container-based solutions are increasing in popularity and thus more companies grav- itate towards them. However, with systems growing larger and more complex there is a general need to introduce container orchestration to manage the increase of containers. LÄS MER

  5. 4. Comparing Three Numerical Methods For Solving The 1D Time Dependent Schrödinger Equation

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Atabak Fathe Jalali; Hugo Åkesson; [2021]
    Nyckelord :;

    Sammanfattning : The purpose of this thesis is to implement three numerical methods for solving and examining the time-dependent Schrödinger equation (TDSE) of the analytically solved quantum harmonic oscillator (QHO) and the, to our knowledge, analytically unsolved double well potential (DW), and to compare the numerical solutions. These methods are the Crank-Nicolson method and two split operator methods of different orders. LÄS MER

  7. 5. Samvetsfrihet och abort - Hör ”samvetsfrihet” hemma i abortvården?

    Master-uppsats,

    Författare :Mozhgan Jalali; [2020-08-26]
    Nyckelord :Samvetsfrihet; Samvete; Abort; Abortsökande kvinnor; Barnmorskor; Abortvården; Professionellt förhållningsätt;

    Sammanfattning : Introduktion: Lagen om samvetsfrihet tillämpas i många länder runt om världen. I Europakonventionens artikel 9 står att envar har rätt till tankefrihet, samvetsfrihet och religionsfrihet, och att inskränkningar bara är lagliga om rättigheten strider mot den allmänna säkerheten eller till skydd för allmän ordning, hälsa eller moral eller till skydd för andra personers fri- och rättigheter.
