  1. 1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Md Mamunur Rashid; [2023]
    Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

  3. 2. Quantum Espionage

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Carlo Ninic Svensson; [2023]
    Nyckelord :Quantum Nano Photonics; SNSPD; OTDR; Nano Kvantfotonik; SNSPD; OTDR;

    Sammanfattning : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. LÄS MER

  4. 3. Laboratory starlight simulator for future space-based heterodyne interferometry

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :William Karlsson; [2023]
    Nyckelord :Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

    Sammanfattning : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. LÄS MER

  5. 4. Design and Implementation of Bluetooth Mesh Outdoor Lighting

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Måns Hofvander; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In the days of IoT and smart homes Bluetooth is in constant development and with it the products that use Bluetooth. Bluetooth mesh is the latest feature and with it comes many opportunities of new products. This report describes the development of an outdoor light system which can be controlled from a website.
