1. 1. Estimating Brain Maturation in Very Preterm Neonates : An Explainable Machine Learning Approach

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Patrik Svensson; [2023]
   Nyckelord :Preterm Neonates; Brain Maturation; aEEG; Explainable Machine Learning; Feature Importance;

   Sammanfattning : Introduction: Assessing brain maturation in preterm neonates is essential for the health of the neonates. Machine learning methods have been introduced as a prospective assessment tool for neonatal electroencephalogram(EEG) signals. LÄS MER

3. 2. Evaluation of Methods for Sound Source Separation in Audio Recordings Using Machine Learning

   Master-uppsats, Linköpings universitet/Kommunikationssystem

   Författare :Amanda Gidlöf; [2023]
   Nyckelord :Sound source separation; signal processing; audio processing; speech enhancement; speaker identification; speech separation; speech processing; speaker separation; single channel; multi channel; cocktail party problem; machine learning; neural network; deep learning; deep neural network; convolutional network; dual-path network; filter-and-sum network; recurrent network; beamforming;

   Sammanfattning : Sound source separation is a popular and active research area, especially with modern machine learning techniques. In this thesis, the focus is on single-channel separation of two speakers into individual streams, and specifically considering the case where two speakers are also accompanied by background noise.

4. 3. PowerPoint Proficiency in Physics Pedagogy : A cognitive perspective on teacher experience

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikundervisningens didaktik

   Författare :Ulf Andersson; Erik Marklund; [2023]
   Nyckelord :cognitive; pedagogy; powerpoint; arousal; pacing; signaling; redundancy; stimuli; physics; didactics; ict; ctml; upper secondary school;

   Sammanfattning : In this small-scale qualitative study we examine PowerPoint presentations using cognitive perspectives (such as the Cognitive Theory of Multimedia Learning, Arousal theory, and Dual Channel processing) to compare teacher experience with a theoretical background. By analyzing collected PowerPoint presentations and interviewing the experienced teachers that created them about their didactic choices, we are able to identify and focus on four aspects of multimedia learning: Pacing, Student Stimuli, Signaling and Redundancy.

5. 4. Dual-polarized geodesic lens in sub-THz

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

   Författare :Wenfu Fu; [2022]
   Nyckelord :beam scanning; dual polarization; fully metallic; geodesic lens; Luneburg lens antenna; THz; strålskanning; korspolarisering; fullt metallisk; geodetisk lins; Luneburg linsantenn; THz;

   Sammanfattning : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. LÄS MER

7. 5. Positioning in Non-Terrestrial Networks

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

   Författare :Soha Emara; [2021]
   Nyckelord :positioning; 5G; satellite; NTN; Technology and Engineering;

   Sammanfattning : In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. LÄS MER
