1. 1. A Comparative Analysis of Whisper and VoxRex on Swedish Speech Data

   University essay from Uppsala universitet/Statistiska institutionen

   Author : Max Fredriksson; Elise Ramsay Veljanovska; [2024]
   Keywords : ASR; Automatic Speech Recognition; Swedish Speech Recognition; Speech Recognition Models; Speech-to-Text; Whisper; VoxRex; Wav2Vec; Model Comparison; Transformer Models; Neural Networks; Machine Learning; WER; Word Error Rate; Transcription;

   Abstract : With the constant development of more advanced speech recognition models, the need to determine which models are better in specific areas and for specific purposes becomes increasingly crucial. Even more so for low-resource languages such as Swedish, dependent on the progress of models for the large international languages. READ MORE

3. 2. Reconstruction of Radio Detector Data using Graph Neural Networks

   University essay from Uppsala universitet/Högenergifysik

   Author : Arnau Serra Garet; [2023]
   Keywords : ;

   Abstract : The current neutrino detectors have been able to detect neutrinos in the range of TeV to 100 PeV, however, ultra high energy (UHE) neutrinos above 100 PeV still remain to be detected. A new neutrino detector, the RNO-G, is currently being constructed in Greenland with the purpose of detecting the first UHE neutrinos using radio antennas capable of measuring the Askaryan pulse generated after a neutrino interaction with the ice molecules.

4. 3. 3D Modeling of Factory Scenarios for 5G Evaluations

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Haodong Zhao; [2023]
   Keywords : ;

   Abstract : 5G is a key enabler for a variety of use cases in smart manufacturing which requires communications with high reliability and low latency. In a dynamic industrial environment, objects such as machines, production lines, storage shelves, robotic arms, and automatically guided vehicles may cause fading and have a large impact on radio propagation.

5. 4. Reinforcement Learning for Multi-Agent Strategy Synthesis Using Higher-Order Knowledge

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gustav Forsell; Shamoun Gergi; [2023]
   Keywords : Higher Order Knowledge; Imperfect Information; Reinforcement Learning; Deep Q- networks; Knowledge Representation; Pursuit Evasion Games;

   Abstract : Imagine for a moment we are living in the distant future where autonomous robots are patrollingthe streets as police officers. Two such robots are chasing a robber through the city streets. Fearingthe thief might listen in to any potential transmission, both robots remain radio silent and are thuslimited to a strictly visual pursuit. READ MORE

6. 5. Increasing energy efficiency of O-RAN through utilization of xApps

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Fredrik Borg; [2023]
   Keywords : telecom; o-ran; ric; xapp; radio access networks; energy efficiency;

   Abstract : As 5G becomes more established and faces widespread roll-out, energy consumption of radio access networks around the globe will increase. Since the high-frequency radio waves used in 5G communication has a shorter effective range compared to the waves used in previous generations, 5G networks will require a higher number of radio units to compensate for their reduced range.
