1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :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;

   Sammanfattning : 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.

   Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

4. 3. Practical Analysis of the Giskard Consensus Protoco

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

   Författare :Leon Sandner; [2023]
   Nyckelord :Distributed Ledger; Blockchain; Consensus Protocol; Giskard; Hyperledger Sawtooth; Distribuerade Huvudbok; Blockchain; Konsensus; Giskard; Hyperledger Sawtooth;

   Sammanfattning : Consensus protocols are the core of modern blockchain systems, such as the Bitcoin, Ethereum, and Algorand networks. Thanks to these protocols, participants in a blockchain network can reach consensus on which blocks to add to a blockchain, to have a consistent chain of blocks in the whole network. LÄS MER

5. 4. Mitt kors - En stötesten för kyrkan? En diskursanalys av initiativet Mitt kors.

   Kandidat-uppsats, Göteborgs universitet/Institutionen för litteratur, idéhistoria och religion

   Författare :Tommy Brandt; [2022-06-20]
   Nyckelord :;

   Sammanfattning : Father Jaques Hamel was murdered on July 26, 2016, while he was celebrating the morning mass in his small church in Saint-Étienne-du-Rouvray in northern France. Hamel was killed by two young men pledging allegiance to the Islamic State. It was a time of growing numbers of reports of political Islamic terror acts on European soil. LÄS MER

7. 5. Attaining Product Level Forward Traceability for Textile & Fashion : Using Block Chain based Traceability Solutions

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Muhammad Hassan Khalid; [2022]
   Nyckelord :Forward traceability; Backward traceability; Granularity; Block chain technology; Traceability technologies; Customer privacy;

   Sammanfattning : The purpose of this thesis is to explore how to enable forward traceability of textile and fashion products at product level, using BC based traceability solutions. The study finds that within TC industry, forward traceability using available technologies (RFIDs, NFCs, QR codes ) is technically possible, however there could be impending regulatory, legal, technical implications of using these technologies.
