  1. 11. Design and evaluation of a solid-state LiDAR system : for wireless distance measurements

    University essay from Uppsala universitet/Signaler och system

    Author : Christian Hagstedt; Sebastian Jönsson; [2022]
    Keywords : Solid-state; LiDAR; Python; Raspberry Pi; Switching regulator; PCB; 3D Printing;

    Abstract : The advent of smarter vehicles coupled with declining costs for solid-state light detection and ranging (LiDAR) sensors unlocks the potential of cheaper devices that experience less mechanical wear while providing smaller form factors. The early state of the market makes evaluating the limited supply of available sensors interesting. READ MORE

  3. 12. Authentication Techniques Based on Physical Layer Attributes

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

    Author : Xintai Liang; [2022]
    Keywords : Wireless security; Spoofing attacks; Physical layer authentication; Channel State Information; Machine learning; Trådlös säkerhet; Spoofing attack; Autentisering av fysiska lager; Kanaltill Stånds Information; Maskinin lärning;

    Abstract : Authentication is an indispensable part of information security. It serves to distinguish legitimate users from unauthorized ones. With the rapid growth of Internet of Things (IoT) devices, authentication of wireless communication is gathering more and more attention. READ MORE

  4. 13. Parameter Update Schemes for Hidden Markov Models applied to Financial Returns

    University essay from Lunds universitet/Matematisk statistik

    Author : Sigfrid Forsberg; [2022]
    Keywords : Markov Chain; Finance; Hidden Markov Model; Generalized Autoregressive Score Model; S P-500; Nikkei; Adaptive Model; Volatility; Regime-switching Model; Line-Search Algorithm; Predictor-Corrector; Quasi-Newton; Mathematics and Statistics;

    Abstract : This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. READ MORE

  5. 14. Short-circuit current detection in electric vehicles

    University essay from Uppsala universitet/Signaler och system

    Author : Max Torbjörner; [2022]
    Keywords : Electric vehicles; Current measurement; Short-circuit; BEV Trucks; BJB;

    Abstract : In recent years the vehicle industries have been making much efforts to reduce the environmentalimpact by switching from the traditional combustion engine to electrification with battery driven electricvehicles. Producing electric trucks requires more batteries and operates at a higher voltage and currentthan commercial electric cars. READ MORE

  6. 15. Boost Converter Inductor Design for High-Power Fuel Cells Using Pareto Optimisation for Single and Coupled Cores
