11. Numerical predictions of heat-transfer applied to electrical machines
Abstract : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. READ MORE

12. Borehole heat store design optimization
Abstract : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. READ MORE

13. Heat treatment of solid wood : effects on absorption, strength and colour
Abstract : Wood is a useful construction material, but it has less desirable properties such as poor durability and poor dimensional stability. These problems can be reduced by using various chemical treatments. Increased environmental awareness has raised the demand for more environmentally friendly methods. READ MORE

14. Protection against cold in prehospital trauma care
Abstract : Background: Protection against cold is vitally important in prehospital trauma care to reduce heat loss and prevent body core cooling. Objectives: Evaluate the effect on cold stress and thermoregulation in volunteer subjects byutilising additional insulation on a spineboard (I). READ MORE

15. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties
Abstract : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. READ MORE
