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. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Hilma Karlsson; [2023]
   Nyckelord :Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

   Sammanfattning : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. LÄS MER

4. 3. Increasing energy efficiency of O-RAN through utilization of xApps

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Fredrik Borg; [2023]
   Nyckelord :telecom; o-ran; ric; xapp; radio access networks; energy efficiency;

   Sammanfattning : As 5G becomes more established and faces widespread roll-out, energy consumption of radio access networks around the globe will increase. Since the high-frequency radio waves used in 5G communication has a shorter effective range compared to the waves used in previous generations, 5G networks will require a higher number of radio units to compensate for their reduced range.

5. 4. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Isa Clementsson; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

7. 5. Impact of aerosol dwell time on the survival of Mycobacterium tuberculosis

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Grisna Isabel Prensa; [2023]
   Nyckelord :;

   Sammanfattning : The airborne pathogen Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB) and claims about 1.6 million deaths annually (WHO, 2022). LÄS MER
