Numerical and experimental damping prediction of a nonlinearly coupled low pressure steam turbine blading verfasst von Christian Siewert, Lars Panning, Christoph Gerber, Pierre Alain Masserey Abstract In this paper, a method for the dynamic analysis of a turbine blading coupled by shrouds and snubbers has been presented. For the analyzed steam turbine blading, the loss factor determined experimentally and the loss factor determined numerically...
A moving boundary problem for periodic Stokesian Hele-Shaw flows authored by Joachim Escher, Bogdan-Vasile Matioc Abstract This paper is concerned with the motion of an incompressible, viscous fluid in a Hele-Shaw cell. The free surface is moving under the influence of gravity and the fluid is modelled using a modified Darcy law for Stokesian fluids. ", keywords = "Hele- Shaw flow, Non-Newtonian fluid, Nonlinear parabolic equation, Quasilinear...

Under both conditions, a comma shaped polarization curve, corresponding to depletion of oxygen, was followed by an increase in current as the cell voltage was lowered. With a theoretical model, we show that at these positive cell voltages and upon the depletion of oxygen, a shift in the Nernst potential occurs allowing for the hydrogen evolution reaction to take place in the cathode catalyst layer. The results of the model are complemented wit...

Activity based links as a ranking factor in semantic desktop search verfasst von Julien Gaugaz, Stefania Costache, Paul Alexandru Chirita, Claudiu S. Firan, Wolfgang Nejdl Abstract Existing desktop search systems, developed as a reaction to the rapidly increasing storage capacities of our hard disks, are an important step towards more efficient personal information management, yet they offer an incomplete solution. The industrial ones are capa...
In spite of the importance of these dams for riparian communities’ livelihoods, their sustainability is nowadays challenged by various management issues underlined by stakeholders’ perception and valuation of ecosystem services provided by the dam system (reservoir-buffer zone). Taking the agro-pastoral dam of Sakabansi village in northern Benin as a case study, we assessed, quantified and valued both actual and potential benefits derived by r...
