2. An evaluation of LoRa transmission parameter selection for indoor positioning
University essay from Jönköping University/JTH, Avdelningen för datateknik och informatikAbstract : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.

4. 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)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.

5. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). READ MORE
