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

   University essay from Linköpings universitet/Informationskodning

   Author : Hilma Karlsson; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

3. 2. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

   University essay from KTH/Fiber- och polymerteknologi

   Author : Felix Bogdan; [2023]
   Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

   Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

4. 3. Quantum Espionage

   University essay from KTH/Tillämpad fysik

   Author : Carlo Ninic Svensson; [2023]
   Keywords : Quantum Nano Photonics; SNSPD; OTDR; Nano Kvantfotonik; SNSPD; OTDR;

   Abstract : 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. READ MORE

5. 4. Varnishing of Fiber-based Closures

   University essay from Lunds universitet/Förpackningslogistik

   Author : Nisha Sunil David; [2023]
   Keywords : Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

   Abstract : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. READ MORE

6. 5. Digital Front End Algorithms for Sub-Band Full Duplex

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.
