16. Transportation Mission-Based Optimization of Heavy Combination Road Vehicles and Distributed Propulsion, Including Predictive Energy and Motion Control
Sammanfattning : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. LÄS MER
17. Smart Energy Grids – Utilization of Space Heating Flexibility
Sammanfattning : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. LÄS MER
18. On motion planning and control for truck and trailer systems
Sammanfattning : During the last decades, improved sensor and hardware technologies as well as new methods and algorithms have made self-driving vehicles a realistic possibility in the near future. Thanks to this technology enhancement, many leading automotive and technology companies have turned their attention towards developing advanced driver assistance systems (ADAS) and self-driving vehicles.

19. Detection of Partial Discharges at Fast Rising Voltages
Sammanfattning : The present demand for higher efficiency and flexibility in the energy sector has ledto an increased use of power electronic generated waveforms as these allow energyconversion between different frequencies including DC. The generated waveformsare usually synthesized by so called Pulse Width Modulation (PWM) techniques,where the desired waveform is approximated by a number of square shaped pulseswith a short rise time.
