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.

   Nyckelord :Physical Layer Security; Power-domain NOMA; Decode and Forward Relay; Jamming in NOMA; Nakagami-m Fading; Relay Transmission; Secrecy Performance.;

   Sammanfattning : Non-orthogonal multiple access (NOMA), with its exceptional spectrum efficiency, was thought to be a promising technology for upcoming wireless communications. Physical layer security has also been investigated to improve the security performance of the system. LÄS MER

4. 3. Digital Technology for Collecting and Handling Traceability Information in A Fish Meal Factory : A Qualitative Grounded Theory Study

   Magister-uppsats, Linnéuniversitetet/Institutionen för informatik (IK)

   Författare :Robert Fröberg; [2022]
   Nyckelord :Traceability; Fish meal; RFID; Blockchain; Internet of Things; Barcode and QR codes; Artificial Intelligence; Cloud computing; Big Data; GPS; Other Technologies; ERP;

   Sammanfattning : As science are growing and new technology emerges in combination with joined rules and laws between countries and unions industries and supply chains are forced to explore and adopt new systems to keep up with this ongoing process. Without modern solutions the information flow can be the Achilles heel that makes companies products less attractive on the market as lack of information sharing can cause tension in questions regarding traceability and sustainability.

5. 4. Bostadsbyggande och utsläppsminskningar : Hur aktörer inom bostadsbyggande och bostadsförsörjning ser på att skapa bostäder som förhåller sig till Sveriges klimatmål och åtgärder för ett minskat byggbehov

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Ellinor Levander; [2022]
   Nyckelord :;

   Sammanfattning : Det är de mänskliga aktiviteterna som genom växthusgasutsläpp orsakar den globala uppvärmningen. För att begränsa utsläppen av växthusgaser har Sveriges stiftat en klimatlag som innebär att Sverige ska var klimatneutralt år 2045. LÄS MER

7. 5. The Enhancement of Women’s Safety Through Smartphones

   Master-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Författare :Hopkins Sophie; [2022]
   Nyckelord :Smartphones; technological developments; safety; technological empowerment; female empowerment; women’s rights.;

   Sammanfattning : This study aims to understand how, and if, women use smartphones to enhance their safety when out of the home. Proven safety is difficult to measure, especially through a cross-sectional study; this research will assess how and if women feel safer through adapting how they use their smartphone. LÄS MER
