1. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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.

2. Shifting Gear in the Auto Industry : Evaluation of the effectiveness of carbon taxes vs. fuel taxes and green innovation in the automotive industry.
Master-uppsats, Jönköping UniversitySammanfattning : Green innovation is currently gaining much global attention, with the rising concern of consumers, authorities, and the broader public about resource depletion and environmental degradation. The automotive industry is a major source of manufacturing waste that degrades ecosystems and biodiversity. LÄS MER
3. Material selection and topology optimization of a shift fork for metal 3D printing
Master-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : In collaboration with Kongsberg Automotive, the thesis focuses on material selection and redesigning the shift fork for additive manufacturing using topology optimization. The shift fork is a component in the gear shifting mechanism in the automotive industry. The current shift fork at Kongsberg is manufactured from aluminum using die-casting. LÄS MER
4. Use of compliant mechanisms in gearbox applications
Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskapSammanfattning : The purpose of this thesis is to prove that the use of compliant mechanisms in gearbox applications is viable. Compliant mechanisms are developed for their implementation in Scania’s hybrid asynchronous gearboxes. LÄS MER
5. Calibration and Estimation of Dog Teeth Positions in Synchronizers for Minimizing Noise and Wear during Gear Shifting
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Electric motors are used more widely in automotive to reducing emissions in vehicles. Due to the decreased usage of internal combustion engines which used to be the main noise source, impacts from synchronizers cannot be ignored during gear shifting, not only causing noise and wear but also delaying gear shifting completion.
