  1. 1. Investigation of Injury Predictors for Rat Neuro Trauma

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Rosetta Maglio; [2024]
    Nyckelord :Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

    Sammanfattning : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. LÄS MER

  3. 2. Finite element density functional description of linear molecules

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Malin Nygren; [2024]
    Nyckelord :;

    Sammanfattning : This report describes a project performed at Linnaeus University with the task of solving the Schrodinger equation for electrons in homonuclear diatomic molecules, using the finite element method in Python. The Schrodinger equation is solved for the hydrogen atom, nitrogen atom, hydrogen molecule and nitrogen molecule using a finite element method. LÄS MER

  4. 3. 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

  5. 4. The Abel-Ruffini Theorem : The insolvability of the general quintic equation by radicals

    Kandidat-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Axel Sjöblom; [2024]
    Nyckelord :;

    Sammanfattning : This thesis explores the topic of Galois theory at a relatively introductory level with the goal of proving the Abel Ruffini theorem. In the first part algebraic structures are considered: groups, ring, fields, etc. Following this, polynomial rings are introduced and the attention is then turned to finite field-extensions. LÄS MER

  7. 5. Den Fullkomligaste Världen: Om Fullkomlighet i den Necessitaristiska läsningen av Spinoza.

    Kandidat-uppsats, Uppsala universitet/Filosofiska institutionen

    Författare :Elliot Lemon; [2024]
    Nyckelord :Principle of Sufficient Reason; Spinoza; Fullkomlighet; Necessitarianism; naturlagar; nödvändighet;

    Sammanfattning : In various parts of Ethics, Spinoza explains both the existence and the necessity of the existence of things, like God, through their perfection(Proofs and Scholium to theorem 11 of part 1 and Scholium 2 for Theorem 33 of part 1). In this paper I attempt to elaborate on the suggestion made by Don Garrett, in Spinoza's Necessitariansim (2018), that Spinoza might have thought that no other world is possible but the one that expresses the greatest possible perfection.
