  1. 1. Stöldskydd i Jordbruket

    Kandidat-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Fabian Coops; Grins Adam; [2023]
    Nyckelord :Elektroteknik; Stöld; LoRaWAN;

    Sammanfattning : This report examines and presents an effective way to alert the owner of a GPS device in case of theft in the agricultural sector. By implementing IR sensors that can be mounted under the object and monitor movements, the owner can receive a warning via SMS and email in case of a potential theft. LÄS MER

    Nyckelord :FMCW; FMCW radar; radar; frequency-modulated radar; noise jamming; frequency-modulated continuous wave radar; FMCW Jamming; Jamming; Pulse Train; Pulse Jamming; Spoofing Attack; Spoofing; Deception; Repeater Jamming; Repeater; Automotive Radar; CFAR; sensor jamming; constant false alarm rate; electronic warfare; EW; FMCW; FMCW radar; frekvensmodulerad dopplerradar; dopplerradar; radar; brusstörning; radarstörning; pulsstörning; pulståg; falskmål; vilseledning; repeterstörning; bilradar; sensorstörning; CFAR;

    Sammanfattning : In this work, the interference sensitivity of an FMCW radar has been evaluated by studying the impact on a simulated detection chain. A commercially available FMCW radar was first characterized and its properties then laid the foundation for a simulation model implemented in Matlab. LÄS MER

  5. 4. "En livsstil för en livstid" : En kvalitativ studie på konsumenters upplevelser av parodireklam inom det vita snusets marknadsföring

    Kandidat-uppsats, Karlstads universitet

    Författare :Konrad Boehm; Jonathan Milner; [2023]
    Nyckelord :parodireklam; vitt snus; marknadsföring; culture jamming;

    Sammanfattning : The purpose of this study is to shed light on the issues surrounding the marketing of white snus, which employs various means to downplay and beautify the product, thus normalizing it as part of everyday life. Using our analytical framework, we have developed spoof advertisements for white snus that convey this problematic nature. LÄS MER

  7. 5. Improving Machinery Safety : Modelling data to explain machine stops and developing a strategy on how to reduce them

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Kristina Leijonborg; Sandra Hammarsten; [2023]
    Nyckelord :;

    Sammanfattning : The purpose of this thesis is to examine how machinery safety at Stora Enso can be increased, with the goal of reducing the amount of machine stops and improving the operational safety within the Packaging Solutions division. To do this, data from the one of the machines at the Jönköping mill has been used for classification and time series modelling. LÄS MER
