One of the most important milestones in history hydropower is invention Kaplan turbine. It a machine stemming from Francis turbine, which Viktor was originally trying to improve. However, it gradually developed into creation completely new solution an impeller with axial flow rate and adjustable blades. The first patent relating dates 1913. Shortly afterwards, turbine became widely used type de...

The nonparametric minimax estimation of an analytic density at a given point, under random censorship, is considered. Although the problem of estimating density is known to be irregular in a certain sense, we make some connections relating this problem to the problem of estimating smooth functionals. Under condition that the censoring is not too severe, we establish the exact limiting behavior ...

To prevent lifetime shortening and premature failure in turbine runners, it is of paramount importance to analyse understand its dynamic response determine the factors that affect it. In this paper, a Kaplan runner analysed air by numerical experimental methods. First, start analysis mode shapes, geometry simplified modelled as bladed disk. Bladed disks with different blade numbers are investig...

This paper demonstrates that the standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a tiny amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. The analysis is centered around a specific measure of wage dispersion— the ratio between the average wage and the lowes...
