  1. 1. The visibility of stellar transients in the Galactic Centre

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

    Author : Jonathan Ström; [2024]
    Keywords : Physics and Astronomy;

    Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

  3. 2. Gate Drive Design for SiC MOSFET Device Characterization : Investigation into the impact of the gate inductance and resistance on the switching behaviour of SiC Power MOSFETs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elochukwu Mbah; [2023]
    Keywords : Silicon Carbide Power MOSFET; Gate Inductance; Gate Resistance; Miller Period; dv dt and di dt transients; Double Pulse Test; Kiselkarbid Power MOSFET; Gateinduktans; Gate Resistance; Millerperioden; dv dt och di dt transienter; Dubbelpulstest.;

    Abstract : Silicon Carbide as a wide-bandgap semiconductor has several physical and electrical advantages over Silicon for high voltage and high frequency applications. SiC as a MOSFET device has a lot of great characteristics like lower on-resistance and low input capacitances. READ MORE

  4. 3. Modelling of electric transients in 24 V power supply systems for commercial vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ajay Ajay; [2023]
    Keywords : ;

    Abstract : Technology is revolutionising every aspect of modern-day transport and evolving rapidly. The traditional electric system of vehicles produced by SCANIA uses a 24 V DC bus system to provide power and ground to all connected electrical units. READ MORE

  5. 4. Monte Carlo analysis of BWR transients : A study on the Best Estimate Plus Uncertainty methodology within safety analyses at Forsmark 3

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Jonathan Eriksson; [2023]
    Keywords : BEPU; Wilks; Uncertainty analysis; BISON; Monte Carlo; BWR; Osäkerhetsanalys; transientanalys; Forsmark;

    Abstract : Transient analyses at Forsmark nuclear power plant are currently performed using realistic computer models in conjunction with conservative estimates of initial- and boundary conditions. This is known as the combined methodology. READ MORE

  6. 5. Predicting power demand and optimizing energy management for fuel cell battery hybrid construction vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Abhishek Karthikeyan; [2023]
    Keywords : Fuel cell; Construction Vehicle; Energy management; Optimization; Model Predictive Control; Load prediction; Auto-correlation; Bränslecell; Byggfordon; Energihantering; Optimering; Modellförutsägande reglering; Belastningsprediktion; Autokorrelation;

    Abstract : The automotive industry has been actively seeking ways to reduce emissions and combat global warming. While pure battery electric vehicles have shown promise in achieving zero-tailpipe emissions, they face challenges in meeting the energy demands of large construction machines like excavators and wheel loaders, due to the heavy batteries required.
