1. 21. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

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

   Author : Saksham Jindal; [2022]
   Keywords : Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

   Abstract : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

3. 22. Investors’ Value Perception of Green and Brown Bond Issuances

   University essay from Lunds universitet/Nationalekonomiska institutionen

   Author : Eric Werleus; Harald Johansson; [2022]
   Keywords : Green bonds; EU-taxonomy; Event study; Cumulative Abnormal Returns; Business and Economics;

   Abstract : The purpose of this study is to investigate if the equity markets react more positively to the issuance announcement of a green bond compared to the issuance announcement of a brown bond and if the introduction of the EU taxonomy has had an effect on the announcement effects. The study contributes to the existing literature by using an updated sample of 511 bonds from 61 issuers stemming from countries within the EU and testing if investor behavior regarding the announcement effect has changed after introducing the EU taxonomy.

4. 23. Railway Fastener Fault Detection using YOLOv5

   University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

   Author : Alva Efraimsson; Elin Lemón; [2022]
   Keywords : Fastener Fault Detection; Object Detection; YOLOv5; Machine Learning; Railway Maintenance; Proactive Maintenance;

   Abstract : The railway system is an important part of the sociotechnical society, as it enables efficient, reliable, and sustainable transportation of both people and goods. Despite increasing investments, the Swedish railway has encountered structural and technical problems due to worn-out infrastructure as a result of insufficient maintenance. READ MORE

5. 24. Dual-polarized geodesic lens in sub-THz

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

   Author : Wenfu Fu; [2022]
   Keywords : beam scanning; dual polarization; fully metallic; geodesic lens; Luneburg lens antenna; THz; strålskanning; korspolarisering; fullt metallisk; geodetisk lins; Luneburg linsantenn; THz;

   Abstract : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. READ MORE

6. 25. Kalman-Filter Design and Evaluation for PMSM Rotor-Temperature Estimation

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Daniel Mårtensson; [2022]
   Keywords : Technology and Engineering;

   Abstract : The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. READ MORE
