16. Hydromechanical Behaviour of Fractures Close to Tunnels in Crystalline Rock
Sammanfattning : The deformation and stiffness properties of rock fractures are important measurable parameters when describing their hydromechanical behaviour. Deformation refers to aperture change. Stiffness refers to the amount of deformation per stress change to which a fracture is subjected. LÄS MER
17. Liksom ett par nya ögon. Frithiof Holmgren och synsinnets problematik
Sammanfattning : This study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. LÄS MER
18. Performance of Compact Heat Exchanger in Non-Perpendicular Cooling Airflows
Sammanfattning : During recent years the main focus in the vehicle industry has been on cutting the fuel consumption and emissions as well as improving the vehicle performance. To be able to meet these demands additional systems are being introduced into the vehicle. LÄS MER
19. Direct Driven Generators for Vertical Axis Wind Turbines
Sammanfattning : Wind power is a renewable energy source that is increasingly used all over the world. Most wind turbines have a horizontal axis of rotation but a few have a vertical axis of rotation. The concept presented in this thesis is a straight-bladed vertical axis wind turbine with a direct driven cable-wound permanent magnet synchronous generator. LÄS MER
20. Direct-Ground Cooling Systems for Office Buildings: Design and Control Considerations
Sammanfattning : Direct-ground cooling systems are defined as systems in which the ground is used as the only source for cooling mainly in commercial buildings. These systems benefit from exchanging heat with the ground, of which its temperature is basically constant below a certain depth year around. LÄS MER
