3. 2. 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

4. 3. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Författare :André Wirthig; [2023]
   Nyckelord :Vibrations; High frequency floors; Sensitive equipment; Technology and Engineering;

   Sammanfattning : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. LÄS MER

5. 4. Autonomous 3D exploration with dynamic obstacles : Towards Intelligent Navigation and Collision Avoidance for Autonomous 3D Exploration with dynamic obstacles

   Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

7. 5. Investigating the Effectiveness of Stealthy Hijacks against Public Route Collectors : Is AS-Path Prepending Enough to Hide from Public Route Collectors?

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

   Författare :Kunyu Wang; [2023]
   Nyckelord :BGP; BGP Hijack; Stealthy IP prefix hijacking; AS-Path Prepending; BGP monitoring; BGP; BGP Hijack; Stealthy IP prefix hijacking; AS-Path Prepending; BGP-övervakning;

   Sammanfattning : BGP hijacking is a threat to network organizations because traditional BGP protocols were not designed with security in mind. Currently, research to combat hijacking is being done by detecting hijacking in real time from Public Route Collectors. LÄS MER
