    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Steven Hendrik Bijl; [2023]
    Keywords : Fusion; JET; MPRu;

    Abstract : This research project centres on advancing data analysis techniques using the Magnetic Proton Recoil Upgrade Neutron Spectrometer (MPRu) for neutron emission spectroscopy during the deuterium tritium experimental campaign (DTE2) at the Joint European Torus (JET). The study aimed to address three pivotal questions, each with implications for optimizing data accuracy, quality, and utility. READ MORE

  4. 3. Computational simulations of the Axion Longitudinal Plasma HAloscope

    University essay from Stockholms universitet/Fysikum

    Author : Tove Klaesson; [2022]
    Keywords : ;

    Abstract : The quantum chromodynamics axion is a very light hypothetical particle that may simultaneously solve the dark matter and the strong CP problem. Recently, a new type of haloscope that can detect the resonant conversion of axions to photons was suggested, The Axion Longitudinal Plasma HAloscope (ALPHA). READ MORE

  5. 4. Multi-Factor Mobile based Access Control Solution

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : August Larsson; Alvin Ohlsson; [2020]
    Keywords : Indoor positioning Wi-Fi Fingerprinting Magnetic Fingerprinting; Technology and Engineering;

    Abstract : In this thesis, alternatives for replacing an RFID card + PIN based access controlsolution for office buildings with a mobile applications are evaluated. The proposedsolutions are based on a probabilistic fingerprinting approach where distributionsof RSSI are approximated and stored in a fingerprint database during an initialoffline phase. READ MORE

  6. 5. 3D Visualized Indoor Positioning System
