1. 11. An empirical study of the impact of data dimensionality on the performance of change point detection algorithms

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

   Author : Léo Noharet; [2023]
   Keywords : Time series segmentation; Change point detection; Multivariate time series; Data dimensionality; Tidsserie-segmentering; Förändringspunkts detektering; Mulitvariabla tidsserier; Data dimentionalitet;

   Abstract : When a system is monitored over time, changes can be discovered in the time series of monitored variables. Change Point Detection (CPD) aims at finding the time point where a change occurs in the monitored system. READ MORE

3. 12. Visual Bird's-Eye View Object Detection for Autonomous Driving

   University essay from Linköpings universitet/Datorseende

   Author : Erik Lidman; [2023]
   Keywords : computer vision; machine learning; neural networks; deep learning; autonomous driving; autonomous systems; datorseende; maskininlärning; neuronnät; djupinlärning; autonom körning; autonoma system;

   Abstract : In the field of autonomous driving a common scenario is to apply deep learningmodels on camera feeds to provide information about the surroundings. A recenttrend is for such vision-based methods to be centralized, in that they fuse imagesfrom all cameras in one big model for a single comprehensive output. READ MORE

4. 13. A socio-technical review of Natural Gas: Resources, environmental and political aspects

   University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Author : Ravi Teja Gorugantu; Sridhar Babu Sanjeevi Rao; [2023]
   Keywords : ;

   Abstract : This report gives a general overview of the natural gas resources in the world, along with its importance as a source of producing energy, and technical uses. It also draws attention to the political issues raised by natural gas exploitation and the steps being taken to address them. READ MORE

5. 14. Improving Change Point Detection Using Self-Supervised VAEs : A Study on Distance Metrics and Hyperparameters in Time Series Analysis

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

   Author : Daniel Workinn; [2023]
   Keywords : Change point detection; Time series data; Segmentation; Machine learning; Data mining; Detektion av brytpunkter; Tidsseriedata; Segmentering; Maskininlärning; Datautvinning;

   Abstract : This thesis addresses the optimization of the Variational Autoencoder-based Change Point Detection (VAE-CP) approach in time series analysis, a vital component in data-driven decision making. We evaluate the impact of various distance metrics and hyperparameters on the model’s performance using a systematic exploration and robustness testing on diverse real-world datasets. READ MORE

6. 15. Fault diagnosis of a variable pole-phase motor

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

   Author : Claes Henriksson; [2023]
   Keywords : Multiphase machine; variable pole-phase machine; fault diagnosis; switch fault; phase fault; harmonic plane decomposition; wound independently controlled stator coil machine; Multifasmaskin; variabel polfasmaskin; feldiagnosticering; brytarfel; fasfel; harmonic plane decomposition; WICSC-maskin;

   Abstract : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. READ MORE
