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.

3. 2. EV charging approaches in remote regions – Analysis of capacity, cost and logistics

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Farhaan Ahamed; Juan Ordonez Marin; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. LÄS MER

4. 3. Comfort through Clothing: North American women’s relationship with clothing through the lens of culture.

   Master-uppsats, Lunds universitet/Avdelningen för etnologi

   Författare :Kara Tullman; [2023]
   Nyckelord :comfort; clothing; material culture; habitus; cultural capital; North American women; female consumers; Bourdieu; market research; emotions.; Cultural Sciences;

   Sammanfattning : Through ethnographic analysis, this thesis investigates the ways in which North American women seek and experience different modes of comfort through their clothing. The material is drawn from a market research study that employs qualitative methods with a spectrum of women across the United States and Canada. LÄS MER

5. 4. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Aravind Srinivasachari; [2023]
   Nyckelord :Indium Tin Oxide; Thin-film characterisation; Magnetron Sputtering; Screen printing; Tandem Solar Cells; Indium-tennoxid; karaktärisering av tunnfilm; magnetronförstoftning; screentryck; tandemsolceller;

   Sammanfattning : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.
