1. 1. 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.

4. 3. Material selection and topology optimization of a shift fork for metal 3D printing

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Rahul Amaralapudi Bala Vardha Raju; Raja Surya Mahesh Thammisetty; [2022]
   Keywords : Additive manufacturing; Topology optimization; Finite Element Analysis; SIMP; Generative design;

   Abstract : 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. READ MORE

5. 4. Use of compliant mechanisms in gearbox applications

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Álvaro Manresa Pérez; Ander Gonzalez Sanchez; [2020]
   Keywords : compliant mechanisms; product development; Finite Element Analysis; additive manufacturing;

   Abstract : 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. READ MORE

6. 5. Calibration and Estimation of Dog Teeth Positions in Synchronizers for Minimizing Noise and Wear during Gear Shifting

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

   Author : Qianyin Kong; [2020]
   Keywords : Synchronizer engagement; gear shifting; dog teeth; particle swarm optimization; Synkroniserare; Växling; Dog-teeth; Partikelsvärmoptimering;

   Abstract : 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.
