1. 16. Making nets more acoustically visible : Floats as passive mitigation measures to reduce bycatch of harbour porpoise (Phocoena phocoena) in gillnets

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Frida Rosshagen; [2023]
   Keywords : toothed whales; harbour porpoise; Phocoena phocoena; incidental capture; bycatch; fisheries; fishing gear; ; gillnet; mitigation; reduction; low-cost; passive acoustic reflector; float;

   Abstract : Incidental capture in fishing gear is today affecting at least 112 marine mammal species worldwide and for many smaller toothed whale species (Odontocete), gillnets are considered to be the largest problem. Although some effective mitigation measures exists, these are often context specific and many might be hard to implement due to reasons such as high costs and maintenance. READ MORE

3. 17. Test rig for gear transmissions in electrical applications

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Gustaf Axelström; [2023]
   Keywords : power circulation; gear test rig; gear testing; effektcirkulation; testrigg; kugghjulstest;

   Abstract : Due to the environmental problems associated with fossil fuels and a big need from the market, the majority of the automotive industry is going towards fully electric vehicles (EVs). To further reduce the environmental footprint there is ongoing research on the use of fossil-free lubricants, if they could be used to lubricate the drive train which could further reduce the use of fossil oil in the automotive industry.

4. 18. Den gudomliga hästen? Hästen i sydskandinavien under bronsåldern

   University essay from Lunds universitet/Arkeologi

   Author : Madeleine Horvath; [2023]
   Keywords : imaging; bronze-age; petroglyphs; horse-gear; iconography; cosmology; status.; History and Archaeology;

   Abstract : This essay is an analysis of the horse during the scandinavian bronze age, more specifically southern scandinavia with a breaking point at circa Gothenburg. The questions regard whether or not the horse was a high status animal during older to younger bronze age in the region and whether or not we can argue this based on rock carvings, horse gear and other pictorial renderings where the horse is present.

5. 19. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

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

   Author : Simon Richter; [2023]
   Keywords : Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

   Abstract : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

6. 20. Efficiency and Roughness Characteristics of Surface Treated Powder Metal Electric Vehicle Gears

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

   Author : Vyshak Mohandas; Sreekuttan Thazhathe Kalathil; [2023]
   Keywords : Gear; FZG-test; Electric vehicles; Mechano-Chemical Surface Treatment; Efficiency; Surface Roughness.; Gear; FZG-test; Elfordon; Mekanisk-kemisk ytbehandling; Effektivitet; Ytsträvhet.;

   Abstract : This thesis presents an experimental research study aimed at identifying the optimal mechano-chemical surface treatment for powder metallurgy gears utilized in electric vehicles (EVs). The primary objective of the study is to determine the most effective surface treatment method in terms of enhancing gear transmission efficiency. READ MORE
