  1. 1. Juice/JDC ion measurement perturbations caused by spacecraft charging in the solar wind and Earth’s magnetosheath

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Derek van Winden; [2024]
    Nyckelord :Juice; Jupiter Icy Moons Explorer; JDC; Jovian plasma Dynamics and Composition analyzer; Particle Environment Package; PEP; Jupiter; Ganymede; Callisto; Europa; solar wind; magnetosheath; spacecraft charging; Spacecraft Plasma Interaction Software; SPIS; charging; plasma; measurement perturbations; perturbation; distortion; particle detector; Institutet för Rymdfysik; IRF; Dublin Institute for Advanced Studies; DIAS; European Space Agency; ESA;

    Sammanfattning :  In July 2031, a new chapter in the exploration of the Jovian system will begin with the arrival of the Jupiter Icy Moons Explorer (Juice) at Jupiter. Launched on April 14 2024 as part of ESA’s Cosmic Vision programme, the mission aims to study Jupiter and its icy Galilean moons Callisto, Europa, and Ganymede. LÄS MER

  3. 2. AI image generation tools as an aid in brainstorming architectural visual designs

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :August Millwood; Clara-Cecilia Dias-Taguatinga; [2023]
    Nyckelord :AI inpainting; architecture; brainstorming; sketching;

    Sammanfattning : This thesis explores the potential of AI generated images as a means to enhance the design, sketching and brainstorming processes in architecture. The study addresses the challenges faced by architects in generating innovative ideas and overcoming cognitive biases during their sketching phase. LÄS MER

  4. 3. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Nyckelord :Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Sammanfattning : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. LÄS MER

  5. 4. Forced response numerical investigation of a transonic compressor rotor

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mariana Pires Gonçalves Toco Dias; [2023]
    Nyckelord :Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER

  7. 5. Los Andes azules de El Cóndor : Sobre la representación del héroe y el antihéroe literario en Cóndores no entierran todos los días de Gustavo Álvarez Gardeazabal

    Kandidat-uppsats, Stockholms universitet/Romanska och klassiska institutionen

    Författare :Edwin Sanchez Duque; [2023]
    Nyckelord :Violencia política; narratología; memoria histórica; prosopopeya; héroe literario; antihéroe; Gaitán; magnicidio; bipartidismo; Bogotazo; Colombia; Stockholm University; Stockholms Universitet; Gustavo Álvarez Gardeazabal; Gardeazabal; Tuluá;

    Sammanfattning : Este trabajo analiza la representación literaria del héroe y el antihéroe y el uso de la figura narrativa prosopopeya en Cóndores no entierran todos los días (1971), una novela del escritor colombiano Gustavo Álvarez Gardeazabal. La novela se centra en la historia de León María Lozano, conocido como El Cóndor, un personaje real que pasó de ser un simple vendedor de quesos en la galería de Tuluá, su pueblo natal en la cordillera occidental de Colombia, a convertirse en un jefe paramilitar que sembró el terror en las poblaciones aledañas a Tuluá durante la guerra civil colombiana, periodo oscuro conocido como La Violencia (1948-1958).
