Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels

Eriksson, Pontus

This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. Di...

Ensemble perturbation smoother for optimizing tidal boundary conditions by assimilation of High-Frequency radar surface currents - application to the German Bight

Barth, Alexander; Alvera, Aida; Gurgel, Klaus-Werner; Staneva, Joanna; Port, Alex; Beckers, Jean-Marie; Stanev, Emil V

High-Frequency (HF) radars measure the ocean surface currents at various spatial and temporal scales. These include tidal currents, wind-driven circulation, density-driven circulation and Stokes drift. Sequential assimilation methods updating the model state have been proven successful to correct th...

Dynamics and local boundary properties of the dawn-side magnetopause under conditions observed by Equator-S

Dunlop, M. W.; Balogh, A.; Baumjohann, W.; Haerendel, G.; Fornacon, K.-H.; Georgescu, E.; Nakamura, R.; Kokubin, S.

Magnetic field measurements, taken by the magnetometer experiment (MAM) on board the German Equator-S spacecraft, have been used to identify and categorise 131 crossings of the dawn-side magnetopause at low latitude, providing unusual, long duration coverage of the adjacent magnetospheric regions an...
