چکیده
Abstract In this paper, various averaging techniques commonly used in turbomachinery applications are analyzed. It is shown how the work average relates to Miller’s mechanical potential and that it is, a certain way, consistent with Hartsel’s cooled turbine efficiency. found key understand these approaches analyze impact entropy variations at inflows have on them. Second-order asymptotics of mixing establish close relationship between flux averages. asymptotic due modes identical for both The average, along analysis, as optimistic vorticity acoustic modes, but pessimistic variations. This explains why potential-based analysis about inflow thus efficiency high inflow, e.g., presence hot streaks or film cooling. Radial discussed their performance shown. Our findings illustrated by means steady unsteady flow simulations 1.5 stage configuration.

Averaging Techniques for Competitive Auctions
We study digital-goods auctions for items in unlimited supply introduced by Goldberg, Hartline and Wright. Since no deterministic algorithms are competitive for this class of auctions, one of the central research issues is how to obtain a nice probabilistic distribution over truthful algorithms. In this paper, we introduce a rather systematic approach to this goal: Consider for example the Samp...

متن کاملSpectral averaging techniques for Jacobi matrices
Spectral averaging techniques for one-dimensional discrete Schrödinger operators are revisited and extended. In particular, simultaneous averaging over several parameters is discussed. Special focus is put on proving lower bounds on the density of the averaged spectral measures. These Wegner type estimates are used to analyze stability properties for the spectral types of Jacobi matrices under ...
متن کاملCoherent ensemble averaging techniques for impedance cardiography
EKG synchronized ensemble averaging of the impedance cardiogram tends to blur or suppress signal events due to signal jitter or event latency variability. Although ensemble averaging provides some improvement in the stability of the signal and signal to noise ratio under conditions of nonperiodic influences of respiration and motion, coherent averaging techniques were developed to determine whe...
