  1. 1. Investigation of the mean photon energy in Kompaneets spectra

    Master-uppsats, KTH/Fysik

    Författare :Richárd Bagi; [2023]
    Nyckelord :Astroparticle Physics; Kompaneets equation; Astropartikelfysik; Kompaneetsekvationen;

    Sammanfattning : The Kompaneets equation describes the spectrum formation when hot fermions are injected into an opaque fermion-photon plasma in thermal equilibrium and inverse Compton-scatterings occur. The equation has three free parameters, the initial plasma thermal energy θ_u, the final plasmathermal energy θ_r and the average photon energy gain y_r. LÄS MER

  3. 2. Two-phase CFD Modelling and Validation : SH204X Master Thesis Project Report

    Master-uppsats, KTH/Kärnenergiteknik

    Författare :Richard Härlin; [2022]
    Nyckelord :Master Thesis; Simulation; Validation; DEBORA; CFD; OpenFOAM; Boiling; Two-phase Thermal-Hydraulics; Fluid Mechanics; Nuclear Power Safety; Examensarbete; Simulering; Validering; DEBORA; CFD; OpenFOAM; Kokning; Tvåfas Termohydraulik; Kärnkraftssäkerhet;

    Sammanfattning : This project deals with two-phase CFD model validation, a subject which is currently under active research due to its complexity. The goal is to create a model that predicts data profiles to an acceptable degree for a wide array of flow conditions. The applications within the nuclear field would mainly be for safety analysis, e.g. LÄS MER

  4. 3. Engagement with institutional pressures in the social impact reporting process: A multiple case study on Swedish NGOs

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Kevin Wihlner; Richard Skårelid; [2022]
    Nyckelord :Social impact; Non-governmental organizations; Performance measurement systems; Accountability; Institutional theory;

    Sammanfattning : Universally there is an ongoing struggle for non-governmental organizations (NGOs) with the implementation of social impact reporting practices for accountability reasons. By drawing on institutional work and insights from a multiple case study, we examine how NGOs implement these practices and how they are shaped by institutional pressures. LÄS MER

  5. 4. Pandemins påverkan på stadskärnan : Vilken effekt har Covid-19 haft på Umeå stadskärnan

    Kandidat-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Jacob Foconi; [2021]
    Nyckelord :Urbanism; City center; Pandemic; Urban crisis planning; Attractiveness; The New Normal; Post-Pandemic urbanism.;

    Sammanfattning : The purpose of this study is to understand the short- and long term implications of the Covid-19 virus on the city center and what is done to revitalize it to a more attractive and available place. This case study is done on Umeå city center, where the municipality is going through a massive transformation and plans to increase its population size from 130 000 to 200 000 by 2050. LÄS MER
