- Detta är en avhandling från Jönköping : Internationella Handelshögskolan
Sammanfattning : This thesis consists of three individual studies and a common introduction. Albeit distinct and self-contained, all studies are devoted to how and why trade flows adjust according to characteristics of markets and attributes of links between markets. LÄS MER
- Detta är en avhandling från Stockholm : Energiteknik
Sammanfattning : A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. LÄS MER

Sammanfattning : Wind power is a renewable energy source that is today the fastest growing solution to reduce CO2 emissions in the electric energy mix. Upwind horizontal axis wind turbine with three blades has been the preferred technical choice for more than two decades. This horizontal axis concept is today widely leading the market. LÄS MER
- Detta är en avhandling från Chalmers University of Technology
Sammanfattning : Two non-linear Rankine-source panel methods are developed and implemented in the same computer code. The first method uses a four-point upwind operator on the free-surface to compute the velocity derivatives and to enforce the radiation condition while the second method uses an analytical expression for the velocity derivatives and a collocation point shift one panel upstream to prevent upstream waves.

Sammanfattning : During the last decades organizations have made large investments in Information Technology (IT). The effects of these investments have been studied in business and academic communities over the years. A large amount of research has been conducted on the relation between the investments in IT and productivity growth. LÄS MER
