3. 32. Development of Detachable Audio Accessory for Surveillance Cameras

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Eric Hammar; Pontus Sjöstrand; [2023]
   Keywords : Technology and Engineering;

   Abstract : Surveillance cameras are used for video monitoring. To complement the video stream, different external accessories can be attached to a camera. The addition of external accessories brings certain limitations in terms of aesthetics and functionality. READ MORE

4. 33. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : David Rydgård; [2023]
   Keywords : Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

   Abstract : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. READ MORE

5. 34. Vibroacoustic Analysis of an OLTC Diverter Switch for Condition Monitoring : Time frequency analysis with Fourier and wavelet transform in combination with multivariate logistic regression for condition monitoring of OLTC diverter switch

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Simon Persson; [2023]
   Keywords : Wavelet transform; CWT; logistic regression; machine learning; ML; vibroacoustic analysis; time frequency analysis; tap changer; diverter switch; power transformer; classification; prediction; condition; vibrations; state prediction; Hitachi Energy;

   Abstract : Vibrations are everywhere around us all the time and we often recognise them as sounds that we can hear and analyse with our brain. In this thesis, data that has been gathered from a diverter switch (DS) in a controlled environment, is analysed. READ MORE

6. 35. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.
