6. Electrification Of A Tiltrotator : Electrifying The Hydraulic Tilt Function
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : As new emission regulations in the EU set more stringent requirements on greenhouse gas (GHG) emissions, original equipment manufacturers (OEM) must find ways to align with the EUs sustainability goals. By transitioning to more electrically driven machinery, operators of off-highway vehicles can benefit from better fuel economy, lower greenhouse gas emissions and less air pollution. READ MORE

7. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. READ MORE

8. A final drive device for torque vectoring in small racing cars
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.
