1. Mining infrequent group of motifs from multidimensional time series: A case study at Alfa Laval AB
Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : In collaboration with an industrial partner, Alfa Laval AB, this thesis discusses a novel approach for identifying operational modes, specifically a cleaning mode, in separator machines without the benefit of labelled data and with very limited operating knowledge. Understanding the operational modes is crucial for comprehending the machine’s behaviour and ensuring its optimal performance. LÄS MER
2. Detection and Analysis of Anomalies in Tactical Sensor Systems through Structured Hypothesis Testing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The project explores the domain of tactical sensor systems, focusing on SAAB Gripen’s sensor technologies such as radar, RWR (Radar Warning Receiver), and IRST (InfraRed Search and Track). The study employs structured hypothesis testing and model based diagnostics to examine the effectiveness of identifying and isolating deviations within these systems. LÄS MER
3. Few-Shot Learning for Quality Inspection
Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : The goal of this project is to find a suitable Few-Shot Learning (FSL) model that can be used in a fault detection system for use in an industrial setting. A dataset of Printed Circuit Board (PCB) images has been created to train different FSL models. LÄS MER
4. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. LÄS MER
5. Machine Vision Based Quality Control and Fault Detection in a Textile Dyeing Machine
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : Fault detection systems come in a variety of formats and are used in many different types of machines and industries. They can be used to perform fast and accurate detection, classification and analysis. The need for user interaction can be decreased and by that the general level of automation can be increased.
