1. Electrical Characterisations of Bearings
Abstract : Mechanical bearings are an integral part of industry, and are used in various places in order to reduce friction between two interacting surfaces and are used to transmit power and loads. Mechanical bearings are one of the most extensively used components within the wind industry, but on the other hand they are also one of the most dominantly failing failed components. READ MORE

2. Electrified Integrated Kinetic Energy Storage
Abstract : The electric car is a technically efficient driveline, although it is demanding in terms of the primary energy source. Most trips are below 50 km and the mean power required for maintaining speed is quite low, but the system has to be able to both provide long range and high maximum power for acceleration. READ MORE

3. Rotordynamic Analysis with Special Reference to Composite Rotors and Internal Damping
Abstract : The present doctoral thesis is concerned with three different rotordynarnic applications; composite rotors, internal damping and microslip in a turbine generator. When a composite shaft has an imperfection, such as differences in the filament winding angle, the eigenfrequencies of the non-rotating shaft depend only on the material stiffness. READ MORE

4. Production and characterisation of pine wood powders from a multi-blade shaft mill
Abstract : Wood is an important raw material for the manufacture of consumer products and in achieving societal goals for greater sustainability. Wood powders are feedstock for many biorefining and conversion techniques, including chemical, enzymatic and thermochemical processes and for composite manufacture, 3D printing and wood pellet production.

5. Dynamic Performance and Design Aspects of Compliant Fluid Film Bearings
Abstract : Due to government regulations together with health and safety reasons, there are increasing demands on reducing hazardous polluting chemicals from fossil fuel power plants. Therefore, more efforts are imposed on using renewable resources such as water, wind, solar and tide to produce clean/green electricity. READ MORE
