  1. 21. Geodesic Lens Antenna for sub-THz Imaging

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

    Author : Joan Mitjans i Blasco; [2021]
    Keywords : ;

    Abstract : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.

  3. 22. Exploring Side-Channel Analysis Targeting FPGA Based RISC-V Architecture : Attempts at Performing Attacks in Preparation for Future PQC Algorithms

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

    Author : Max Vilhelmson Näf; [2021]
    Keywords : Post-Quantum Cryptography; Field Programmable Gate Array; Neural Network; Learning With Errors Rounding; Key Encapsulation Mechanism; Post-Quantum Cryptography; Field Programmable Gate Array; Neural Network; Learning With Errors Rounding; Key Encapsulation Mechanism;

    Abstract : Many public-key cryptosystems currently in use are threatened by the possibility of large-scale quantum computers being built in the future. To counteract this, a process of developing quantum-resistant cryptographic algorithms is underway. This process also emphasizes the importance of protecting algorithms from Side-Channel Analysis (SCA). READ MORE

  4. 23. Validation of the Westinghouse BWR nodal core simulator POLCA8 against Serpent2 reference results

    University essay from KTH/Fysik

    Author : Mathilde Gaillard; [2021]
    Keywords : Nodal Core Analysis; Monte Carlo Methods; CBH Effects; Nodal kärnanalys; Monte Carlo-metoder; CBH-effekter;

    Abstract : When a new nodal core simulator is developed, like all other simulators, it must go through an extensive verification and validation effort where, in the first stage, it will be tested against appropriate reference tools in various theoretical benchmark problems. The series of tests consist of comparing several geometries, from the simplest to the most complex, by simulating them with the nodal core simulator developed and with some higher order solver representing the reference solution, in this case on the Serpent2 Monte Carlo transport code.

  5. 24. Undocumented oil leakages : A study about stern tube seals and leakages

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Johan Lundberg; [2021]
    Keywords : Oil lubricated stern tube; Water lubricated stern tube; Oil; Oil leakage; Oil spill; stern tube seal; vessel; Oljesmord propellerhylsa; Vattensmord propellerhylsa; Olja; oljeutsläpp; Oljeläckage; propellerhylstätning; Fartyg;

    Abstract : The majority of the vessels in the commercial fleet utilize oil lubricated stern tubes. Unfortunately, this brings about a risk of oil leaking from the stern tube into the marine environment if the stern tube seal would become worn or damaged by foreign materials. Previous studies concluded that, on average, 2. READ MORE

  6. 25. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Claes Sjöberg; Jens Kårhammer; [2021]
    Keywords : strukturkalkning; dragkraftsbehov; jordmotstånd; penetrometermotstånd; aggregatbildning; lerjord; pH;

    Abstract : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. READ MORE
