1. Towards model-based development of heavy truck synchronizers
Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. LÄS MER
2. On synchronization of heavy truck transmissions
Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. LÄS MER
3. Gear engagement control for transmissions in hybrid electric vehicles
Sammanfattning : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. LÄS MER
4. Design of Wireless Communication Systems -- Issues on Synchronization, Channel Estimation and Multi-Carrier Systems
Sammanfattning : This thesis deals with certain aspects in the design of wireless communications systems. It is focused on problems related to the mobile or wireless channel: synchronization, channel estimation and design of wireless orthogonal frequency division multiplex (OFDM) systems. LÄS MER
5. Synaptic uncoupling in the mouse cochlea induced by noise or cisplatin and its clinical relevance
Sammanfattning : The cochlea has an autonomous circadian clock that controls auditory function and increases vulnerability to noise trauma during the active phase. The mechanisms regulating the circadian control of the auditory system are poorly understood. LÄS MER
