1. 11. Club Head Tracking : Visualizing the Golf Swing with Machine Learning

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Fredrik Herbai; [2023]
   Nyckelord :Golf; Machine learning; Neural network; XGBoost; Interpolation; Deep learning; Data collection; Data augmentation;

   Sammanfattning : During the broadcast of a golf tournament, a way to show the audience what a player's swing looks like would be to draw a trace following the movement of the club head. A computer vision model can be trained to identify the position of the club head in an image, but due to the high speed at which professional players swing their clubs coupled with the low frame rate of a typical broadcast camera, the club head is not discernible whatsoever in most frames.

3. 12. Optimizing Load Balancing inRaytracing for Radio Frequency PropagationPredictive models developed for simulation systems

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Wenhao Zhu; [2023]
   Nyckelord :;

   Sammanfattning : This thesis presents two predictive models with the aim of pre-allocating memory efficiently in the Ericsson Radio Frequency Propagation Simulation System through the prediction model, so as to achieve the effect of load balancing. The proposed approaches utilize interpolation and the Gradient Boosting Decision Tree (GBDT) method from machine learning for prediction and  apply both methods in multiple test scenarios. LÄS MER

4. 13. Evaluating GPU for Radio Algorithms : Assessing Performance and Power Consumption of GPUs in Wireless Radio Communication Systems

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

   Författare :Albin André; [2023]
   Nyckelord :GPU; CUDA; Signal Processing; Radio; Algorithms; GPU; CUDA; Signalbehandling; Radio; Algoritmer;

   Sammanfattning : This thesis evaluates the viability of a Graphics Processing Unit (GPU) in tasks of signal processing associated with radio base stations in cellular networks. The development of Application Specific Integrated Circuits (ASICs) is lengthy and highly expensive, but they are efficient in terms of power consumption. LÄS MER

5. 14. Mispronunciation Detection with SpeechBlender Data Augmentation Pipeline

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

   Författare :Yassine Elkheir; [2023]
   Nyckelord :Computer-assisted pronunciation training CAPT ; Automatic Speech Recognition ASR ; Mispronunciation Detection MD and Data Augmentation; Datorstödd uttalsträning CAPT ; automatisk taligenkänning ASR ; upptäckt av felaktigt uttal MD och dataförstärkning;

   Sammanfattning : The rise of multilingualism has fueled the demand for computer-assisted pronunciation training (CAPT) systems for language learning, CAPT systems make use of speech technology advancements and offer features such as learner assessment and curriculum management. Mispronunciation detection (MD) is a crucial aspect of CAPT, aimed at identifying and correcting mispronunciations in second language learners’ speech. LÄS MER

7. 15. Adjoint optimization of a liquid-cooled heat sink

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Roven Pinto; [2023]
   Nyckelord :Adjoint method; topology optimization; porosity; OpenFOAM;

   Sammanfattning : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. LÄS MER
