  1. 1. 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

  3. 2. Matematiska modeller och datorberäkningar för ytdiffusion

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Jessica El-jabaoui; Felicia Hägerström; Christian Jenei; [2023-11-28]
    Nyckelord :Ytdiffusion; Krökningsflöde; Modifierade Allen-Cahn ekvationen; Geometriska flöden; Fasfält.;

    Sammanfattning : I detta arbete undersöks geometriska flöden och hur dessa kan implementeras numeriskt med fasfältsmodeller. Speciellt ligger fokus på ytdiffusion, som är ett geometriskt flöde där ändliga ytor i andra dimensionen konvergerar mot en cirkel och arean bevaras. LÄS MER

  4. 3. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Emrah Tortumlu; [2023]
    Nyckelord :Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Sammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  5. 4. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lorenzo Obersnel; [2023]
    Nyckelord :Eneregetic Neutral Atoms; Venus; Ion precipitation; ENA precipitation; Atomi Neutri Energetici; Venere; precipitazione di ioni; precipitazione di atomi neutri; Energisk Neutral Atom; Venus; Utfällningen joner; Utfällningen Energisk Neutral Atom;

    Sammanfattning : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. LÄS MER

  7. 5. A Climate, Land, Energy, and Water Nexus Assessment of Ethiopia

    Master-uppsats, KTH/Energisystem

    Författare :Pegah Atarian; [2023]
    Nyckelord :;

    Sammanfattning : Ethiopia is a landlocked country located in northeast Africa with a predominantly rural population dependent on rainfed agriculture and traditional biomass. The Ethiopian economy is growing fast and as it continues to grow, so does the demand for water, food, and energy. LÄS MER
