1. On power loss minimisation for heavy vehicles with axle-wise and modular electrical propulsion and friction braking
Abstract : The main challenges for battery electric heavy vehicles are improving the payload capacity and driving range for different applications. These are mainly influenced because of battery power density, different vehicle configurations, and powertrain design. READ MORE

2. EMC in railway systems : measurements, modeling and analysis
Abstract : The subject of this study and resulting thesis was to investigate the electromagnetic compatibility (EMC) problems in the multi-electrical signaling circuitry along a railway track. These signaling systems have been expanding over time from buried multi-wired electrical copper cables to optical fiber cables, sometimes located parallel to the contact line in the catenaries.

3. Automation and traction control of articulated vehicles
Abstract : Articulated machines such as load-haul-dump machines, wheel loaders and haulers operate in many different environments and driving conditions. In particular they need to be able to perform well with road conditions and loads that can change drastically, setting hard requirements on performances and robustness. READ MORE

4. Power Control Systems in a Flywheel based All-Electric Driveline
Abstract : Flywheel systems are attractive in hybrid and electric vehicles due to their ability to handle power during acceleration and braking. The combination of a flywheel device with a battery source has several advantages such as high peak power capacity, high energy density and reduction in the number of charge/discharge cycles of the battery.

5. Optimal Railroad Power Supply System Operation and Design : Detailed system studies, and aggregated investment models
Abstract : Railway power supply systems (RPSSs) differ mainly from public power systems from that the loads are moving. These moving loads are motoring trains. Trains can also be regenerating when braking and are then power sources. These loads consume comparatively much power, causing substantial voltage drops, not rarely so big that the loads are reduced.
