1. 1. Using NeRF- and Mesh-Based Methods to Improve Visualisation of Point Clouds

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Vilma Ylvén; Oscar Montelin; [2024]
   Nyckelord :Technology and Engineering; Mathematics and Statistics;

   Sammanfattning : In recent years, the field of generating synthetic images from novel view points has seen some major improvements. Most importantly with the publication of Neural Radiance Fields allowing for extremely detailed and accurate 3D novel views. LÄS MER

3. 2. Night Vision Goggle Simulation in a Mixed Reality Flight Simulator with Seamless Integrated Real World

   Magister-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

   Författare :Sofia Sproge; [2024]
   Nyckelord :Night vision goggles; NVG; Mixed Reality; Flight simulator; Video see-through; VST; Color transfer algorithm; Seamless integration; Post processing;

   Sammanfattning : Night vision goggles (NVGs) are optical devices used to enhance human vision at low light conditions such as nighttime. The image seen through the goggles is brightened but with the consequence of introduced visual limitations and illusions. LÄS MER

4. 3. Analyzing Toxicity in YouTube Comments with the Help of Machine Learning

   Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Sasan Dehkhoda; Jasmyn Ali Gunica; [2023]
   Nyckelord :Toxic comments; YouTube; Machine Learning; Natural Language Processing;

   Sammanfattning : Toxic comments are overall likely to make someone feel uncomfortable and leave a discussion and are therefore potentially problematic. Toxic comments occur online on various social media, and depending on the site, get detected manually or via machine learning algorithms (or both), and removed depending on the severity and other factors.

5. 4. 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.

7. 5. Interactive 360-degrees video : User experience, user interface and heads-up display for educational training scenarios in nursing education

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :William Glinghammar; [2023]
   Nyckelord :360-degrees video; interaction design; user interface; heads-up display; multimedia learning; user experience; nursing education;

   Sammanfattning : This thesis explores the user experience, potential and design principles of a HUD-based user interface in combination with interactive 360-degrees videos in nursing education. A HUD-based 360-degrees video was designed around a previously recorded scenario in an emergency room and user tests were conducted on nurse educators, working nurses and a nurse student. LÄS MER
