  1. 1. Physical Layer Security for MIMOTransmission of Short PacketCommunications

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Varun Duvva; Bharath Reddy Anugu; [2024]
    Nyckelord :Physical Layer Security; Multiple-Input Multiple-Output; Short Packet communication; Maximum Ratio Combining; Maximum Ratio Transmission; and Beamforming;

    Sammanfattning : This thesis explores the practical application of Physical Layer Security (PLS) inMultiple-Input Multiple-Output (MIMO) systems, particularly focusing on ShortPacket Communication (SPC). The aim is to enhance the security of wireless com-munications against eavesdropping threats. LÄS MER

  3. 2. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Joel Fransson Forsberg; [2023]
    Nyckelord :Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Sammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER

  4. 3. Inomhuspositionering : Ett användningsområde

    Kandidat-uppsats, Högskolan i Gävle/Datavetenskap

    Författare :Robin Törnblom; [2022]
    Nyckelord :Inomhuspositionering; IPS; Infraröd; lokaloptimering; lokalnyttjande;

    Sammanfattning : Sedan 1960-talet har globala navigationssystem (GNSS) framgångsrikt kartlagt vår planet och möjliggjort en global positionering. Mognaden av GNSS tillsammans med utvecklandet av ny teknik och enheter har skapat en ökad efterfrågan av positionering inomhus. LÄS MER

  5. 4. Ömsesidighet eller våldtäkt? : Våldtäktsbrottets gråzon - En rättslig analys

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Avdelningen för juridik

    Sammanfattning : On the first of july 2018 Sweden adopted a new definition of rape and introduced a legislation for rape when the preparator acts negligently. It´s criminalized when the suspect undertakes the sexual act with lack of consent. Depending on if the preparator did it with intent or negligently defines if it´s rape or rape based on negligence.

  7. 5. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Bakhtiar Afzalan; [2021]
    Nyckelord :Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Sammanfattning : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. LÄS MER
