  1. 1. 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

  3. 2. Common practices and knowledge about African swine fever amongst pig farmers in the Dominican Republic

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Ellinor Nilsson Fuglsang; [2023]
    Nyckelord :Disease transmission; Caribbean; Biosecurity; Swine; Outbreak; Pig production;

    Sammanfattning : In the summer of 2021, African swine fever (ASF) made its reappearance in the Dominican Republic after 40 years of absence. The disease is known for its high mortality amongst pigs and its consequences for human welfare. LÄS MER

  4. 3. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Jonas Beling; [2023]
    Nyckelord :ion; physics; ion physic; scattering; desorption; sputtering; jon; fysik; jonfysik;

    Sammanfattning : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. LÄS MER

  5. 4. 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

  7. 5. Full Duplex for Joint Communication and Sensing in 6G.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Soumya Jandhyala; [2023]
    Nyckelord :;

    Sammanfattning : Background: 6G mobile communication is one of the fastest-growing fields of technology. The present 5G mobile networks will not be adequate to meet society’s wireless connectivity demand in the near to mid-term future. A new generation of wireless mobile networks has to be developed to address this demand. LÄS MER
