  1. 21. Calculating Minimum Detectable Activity for a moving scintillator detector using real-time speed measurement : Implementing a monitoring system to improve accuracy of surface contamination measurement systems

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

    Författare :Artur Amcoff; Oscar Persson; [2021]
    Nyckelord :Minimum Detectable Activity MDA ; Surface contamination; ISO 11929; Alpha α radiation; Beta β radiation; Detection limit; Counting efficiency; Minsta detekterbara aktivitet; Ytkontaminering; ISO 11929; Alfa α strålning; Beta β strålning; Detektionsgräns; Radioaktiv mäteffektivitet;

    Sammanfattning : Surface contamination occurs in nuclear facilities, something that is important to detect easily and efficiently. Using today’s methods to detect nuclear surface contamination may cause certain inconsistencies as the human operator is solely trusted to keep the detector at the correct distance and move it at the correct speed.

  3. 22. Development of methods for detection of radioactive aerosols of special importance for the ESS facility

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Carlström; [2021]
    Nyckelord :alpha spectrometry; radioactive aerosols; spectrum simulation;

    Sammanfattning : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. LÄS MER

  4. 23. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Oskar Evert Johansson; [2021]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Sammanfattning : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. LÄS MER

  5. 24. Aktivitetshalsband på katt : verifiering av tillförlitligheten i mätningar av katters fysiska aktivitet

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Kent Anders Mathiasson; [2021]
    Nyckelord :accelerometer; accelerometri; aktivitetshalsband; aktivitetsmonitor; felin; fysisk aktivitet; katt;

    Sammanfattning : Andelen äldre katter ökar i Sverige och med åldern ökar diabetes och ledsjukdomar, som osteoartrit. Tidig diagnos av dylika sjukdomar är viktigt för katternas hälsa och välmående. LÄS MER

  7. 25. Anomaly Detection using a Deep Learning Multi-layer Perceptron to Mitigate the Risk of Rogue Trading

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

    Författare :Erik Hedström; Philip Wang; [2021]
    Nyckelord :Deep Learning; Machine Learning; Multi-layer Perceptron MLP ; Neural network; Rogue Trading;

    Sammanfattning : The term Rogue Trading is defined as the activity of someone at a financial organisation losing a large amount of money in bad or illegal transactions and trying to hide this. The activity of Rogue traders exposes financial organisations to huge risks and may lead to the organisation collapsing, which will affect other stakeholders like, for example, the customers. LÄS MER
