  1. 16. Simulation of Quantum Cascade Lasers

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Zakaria Mohamed; [2023]
    Nyckelord :Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Sammanfattning : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. LÄS MER

  3. 17. Methodology for evaluation of long-term mechanical properties of viscoelastic materials

    Master-uppsats,

    Författare :NIKHIL JOSEPH EBI; [2023]
    Nyckelord :;

    Sammanfattning : Additive manufacturing (AM) enables the fabrication of complex geometries using layer-by-layerdeposition of materials like polymers and metals. However, predicting the long-term viscoelasticcharacteristics of AM polymer parts is challenging due to limited available data. LÄS MER

  4. 18. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

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

    Författare :Fan Yang; [2023]
    Nyckelord :Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

    Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER

  5. 19. Influence of Nrf2 Activators and Keap1 Inhibitors on Antioxidative Phenotypes of THP-1-Derived M1 and M2 macrophages: Therapeutic Potential for Systemic Lupus Erythematosus

    Master-uppsats, Uppsala universitet/Institutionen för immunologi, genetik och patologi

    Författare :Leo Svahn; [2023]
    Nyckelord :NRF2; KEAP1; THP-1; M1; M2; SLE;

    Sammanfattning : POPULAR SCIENTIFIC SUMMARY Systemic lupus erythematosus (SLE) is not your average disorder. It behaves like a mischievous troublemaker, wreaking havoc throughout the body, causing inflammation that affects multiple organs. LÄS MER

  7. 20. Digitalization and SafetyA case study of a large company’s digitalization approach and its impact on occupational health and safety

    Master-uppsats, KTH/Ergonomi

    Författare :Prathamesh Bachche; [2023]
    Nyckelord :Digitalization; Occupational Health and Safety; Digital tools; Human Factors; Ergonomics.;

    Sammanfattning : This thesis aims to evaluate the implementation of digital tools in terms of worker and manager experiences and perceptions at Stora Enso Packaging Solutions with respect to safety and where the opportunities for improvement are for these technologies to enhance the workplace safety through an external vantage point. The goal is to identify factors at the design and implementation phase of the digital tools and provide suggestions on improvements. LÄS MER
