    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Bogdan Radu Racsi; [2023]
    Nyckelord :high pressure die casting; HPDC; energy efficiency; cast house remelting; internal aluminium scrap; melting furnace; melting and holding furnace; drivers; barriers;

    Sammanfattning : The aluminium industry is anticipated to witness a surge in demand, with projectionsof a two to three-fold increase by 2050. Meeting environmental objectives andaddressing the growing emphasis on sustainability from both the industry andconsumers seeking eco-friendly products present significant challenges. LÄS MER

  3. 2. Effects of Energy Performance Improving Measures on a 1990's Brick House in Southern Czech Republic : Computer Simulations using IDA-ICE

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Vaclav Panek; [2023]
    Nyckelord :Final energy demand; Primary energy demand; Energy performance; Refurbishment; Single-family house; Space heating;

    Sammanfattning : The residential sector was responsible for 25% of the Final Energy Demand (FED) in the European Union in 2015. Countries in Central and Eastern Europe such as the Czech Republic are particularly concerned with ensuring security of supply at the lowest possible cost in recent years. LÄS MER

  4. 3. Tillbaka till framtiden? : Gengas som ett alternativ till höga priser på el, bensin och diesel

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

    Sammanfattning : Första och andra världskrigen medförde stora importrestriktioner för bensin och diesel och Sverigestod inför en potentiell kris. Lösningen till drivmedelsbristen var gengas som produceras genom attförbränna träd eller kol i en syrefattig miljö. LÄS MER

  5. 4. Silicon Drift Detector Simulations for Energy-Dispersive X-ray Spectroscopy in Scanning Electron Microscopy

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Sebbe Blokhuizen; [2023]
    Nyckelord :X-ray spectroscopy; Silicon drift detector; Scanning Electron Microscopy; Detector Simulation;

    Sammanfattning : Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy (SEM-EDS) is a widely applied elemental microanalysis method. The integration of silicon drift detectors (SDDs) has notably enhanced EDS performance, enabling precise elemental identification due to its large sensitive area and low output capacitance. LÄS MER

  7. 5. A comparative study on anapproach to print Industrial Toolsvia Additive Manufacturing for Volume Production from Technical, Economic, and Environmental aspects

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Purav Mukesh Thaker; [2023]
    Nyckelord :;

    Sammanfattning : The thesis explores a path to use Additive Manufacturing as an approach for volume production of Industrial Technique Business Area Tools, addressing the challenges of manufacturing complexity, low volume demand, and quality control for both Atlas Copco Industrial Technique industrial tools (Tool 1 & Tool 2). This study is done in cooperation with Atlas Copco Industrial Technique, comparing the technological, economic, and environmental performance of AM versus the current manufacturing approach from a round bar.
