1. 11. Cost Optimization of Volumetric Surveillance for Sky Monitoring : Towards Flying Object Detection and Positioning

   Författare :Hiba Alqaysi; Mattias O'Nils; Najeem Lawal; Faisal Qureshi; Fabio Poiesi; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; image processing; deep learning; YOLOv4; smart cameras;

   Sammanfattning : Unlike surface surveillance, volumetric monitoring deals with three-dimensional target space and moving objects within it. In sky monitoring, objects fly within outdoor and often remote volumes, such as wind farms and airport runways. Therefore, multiple cameras should be implemented to monitor these volumes and analyze flying activities. LÄS MER

3. 12. High Frequency (MHz) Planar Transformers for Next Generation Switch Mode Power Supplies

   Författare :Radhika Ambatipudi; Kent Bertilsson; Bengt Oelmann; Jesus Doval Gandoy; Hans-Peter Nee; Torbjörn Thiringer; Göran Thungström; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Planar Magnetics; DC-DC Converters; Switch Mode Power Supplies; MHz Frequency Region;

   Sammanfattning : Increasing the power density of power electronic converters while reducing or maintaining the same cost, offers a higher potential to meet the current trend inrelation to various power electronic applications. High power density converters can be achieved by increasing the switching frequency, due to which the bulkiest parts, such as transformer, inductors and the capacitor's size in the convertercircuit can be drastically reduced.

4. 13. Spectroscopic and Microscopic X-ray Fluorescence Analysis for Environmental and Industrial Applications

   Författare :Siwen An; Börje Norlin; Göran Thungström; David Krapohl; Yuying Huang; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Heavy metals are well-known environmental pollutants due to its potential impact on associated ecosystems and human health. Thus, it is important to monitor the levels of heavy metals in the environment. X-ray fluorescence (XRF) analysis is a powerful and effective screening tool in measuring the concentration of multi-elements simultaneously. LÄS MER

5. 14. X-ray Fluorescence Spectrometry for Environmental Applications

   Författare :Siwen An; Göran Thungström; Börje Norlin; Richard Brenner; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Heavy metal contamination in environmental applications is particularly important because of its potential impact on associated ecosystems and human health. At present, monitoring of heavy metals is usually done by taking and preparing samples for off-line laboratory measurements. LÄS MER

7. 15. Oberoendets praktik

   Författare :Ewa Andersson; Susanna Öhman; Gunnar Augustsson; Katarina Giritli-Nygren; Mats Trondman; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; independent actors; practice; autonomous; heteronomous; capital; position; Oberoende aktörer; praktik; autonom; heteronom; kapital; position;

   Sammanfattning : The Independent PracticeDuring the last hundred years, the music industry has evolved with the record labels playing a central role. However, many argue that this situation is about to change as record sales have decreased during the last ten years. LÄS MER
