1. 1. EXTRACTING REGIONS OF INTEREST AND DETECTING OUTLIERS FROM IMAGE DATA

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Jessica Ström; Erik Backhans; [2023]
   Keywords : Artificial Intelligence AI ; Machine Vision; Outlier Detection; Autoencoders; Neural Networks; Region Of Interest ROI ;

   Abstract : Volvo Construction Equipment (CE) are facing the challenge of vibrations in their wheel loaders that generate disruptive noise and impact the driver's experience. These vibrations have been linked to the contact surface between the crown wheel and pinion gear in the vehicles drive-axles. READ MORE

3. 2. Arbitrary motion Synthetic Aperture Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Filip Alberius; Erik Rolander; [2023]
   Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

   Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

4. 3. Economic repercussions of power outages for Swedish electrical distribution companies

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Abstract : The Swedish distribution grid plays a crucial role in providing citizens of Sweden with electricity to power their regular life. Without power a lot of essential societal services malfunction. Therefore, it is of utmost importance that the power grid operates optimally. READ MORE

5. 4. Semiconducting TiO2 for High Performance Ferroelectric Tunnel Junctions

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Erik Wikare; [2022]
   Keywords : Technology and Engineering;

   Abstract : The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. READ MORE
