1. 16. Basil-GAN

   University essay from KTH/Matematisk statistik

   Author : Jonatan Risberg; [2022]
   Keywords : GAN; mathematical statistics; deep neural networks; generative models; latent space exploration; sequential data; GAN; matematisk statistik; djupa neurala nätverk; generativa modeller; utforskning av latenta rum; sekventiell data;

   Abstract : Developments in computer vision has sought to design deep neural networks which trained on a large set of images are able to generate high quality artificial images which share semantic qualities with the original image set. A pivotal shift was made with the introduction of the generative adversarial network (GAN) by Goodfellow et al.. READ MORE

3. 17. Assessing Machine Learning Algorithms to Develop Station-based Forecasting Models for Public Transport : Case Study of Bus Network in Stockholm

   University essay from KTH/Transportplanering

   Author : Mahsa Movaghar; [2022]
   Keywords : Public transport; ridership; machine learning; Multiple Linear Regression; Decision Tree; Random Forest; Bayesian Ridge Regression; Neural Networks; Support Vector Machines; K-Nearest Neighbors;

   Abstract : Public transport is essential for both residents and city planners because of its environmentally and economically beneficial characteristics. During the past decade climatechange, coupled with fuel and energy crises have attracted significant attention toward public transportation. READ MORE

4. 18. Commissioning of a FPGA/DSP unit for Centralized Control of a Variable Phase Pole Multiphase Machine

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

   Author : Jonas Hansson; [2022]
   Keywords : Harmonic Plane Decomposition; Multiphase Electrical Machine; Wound Independently-Controlled Stator Coils; System on a chip; Control Implementation; Hardware Design ; Motorstyrning; Asynkronmotor; Multifasmaskin; Programmering; Systemkrets; Hårdvarukonstruktion;

   Abstract : Multiphase Electrical Machines (MPEMs) with variable phase-pole configurations have recently gained interest as it offers advantages such as a larger operating range and improved fault tolerance compared to more traditional MPEMs. The current state-of-the-art modeling and control method, Vector Space Decomposition (VSD), has the drawback of introducing discontinuities in the model when transitioning from one phase-pole configuration to another.

5. 19. LSTM Feature Engineering Through Time Series Similarity Embedding

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Sebastian Bångerius; [2022]
   Keywords : Embedding; time series; LSTM; feature engineering; DTW; correlation; prediction;

   Abstract : Time series prediction has many applications. In cases with simultaneous series (like measurements of weather from multiple stations, or multiple stocks on the stock market)it is not unlikely that these series from different measurement origins behave similarly, or respond to the same contextual signals.

6. 20. Continuous Control SetModel Predictive Control of Permanent Magnet Synchronous Motor

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

   Author : Prithivirajan Subramaniyane; [2022]
   Keywords : Interior permanent magnet synchronous motor; Continuous control set-Model predictive control; Linear quadratic regulator; Quadratic programming; Interior permanent magnet synchronous motor; Continuous control set-Model predictive control; Linear quadratic regulator; Quadratic programming;

   Abstract : The thesis provides design methods for developing Continuous Control SetModel Predictive Control and Linear Quadratic Regulator for Interior mounted Permanent Magnet Synchronous Motor drive. The software for these controllers are implemented in the prototype motor at China Euro Vehicle Technology (CEVT) to estimate the computation time. READ MORE
