The paper describes the flutter stability assessment of a steam turbine rotor and application multi-disciplinary shape optimization procedure to obtain new flutter-free profile. investigated test case consists last stage representative modern industrial blading, firstly presented by Durham University intensively during years. aerodamping results original geometry, obtained non-linear method, ar...

The theory of surface wave generation, in viscous flows, is modified by replacing the linear-logarithmic shear velocity profile, air, with a model which links smoothly linear and logarithmic layers through buffer layer. This profile includes effects air flow turbulence using damped mixing-length model. In water, an exponential used. It shown that this coupled shear-velocity gives better agreeme...

In this paper, for efficient energy consumption through the residential demand response in the smart grid, an optimization algorithm, which can provide a schedule plan for the home appliance usages, is proposed. In order to minimize the average electricity price based on the time-varying electricity price in conjunction with the peak hourly load, which decides the capacity of the electric suppl...

This paper presents a new decision tree learning algorithm that takes account of costs of misclassification. The algorithm is based on the hypothesis that non-linear decision nodes provide a better basis for cost-sensitive induction than axis-parallel decision nodes and utilizes discriminant analysis to construct non-linear cost-sensitive decision trees. The performance of the algorithm is eval...

side weir is a flow control structure that used extensively in irrigation and drainage as well as sewer networks. throughout the present research, a study comprised of 162 experiments was done on sharp-crested semi-circular side weir. since the height in this side weir varies along its length, this feature enables it to more properly control flood than rectangular side weirs in various flood co...

Soil erosion is one of the vital factors contributing to the loss of fertility and environmental degradation. Generally accepted diagnostics of eroded soils is based on comparison of the sloping soils profile depth with the watershed soils. In this case, there is a separate problem of slope soils with a naturally shortened profile and eroded soils. Formation of the soil’s natura...

There are many evidences that human serum paraoxonase activity modifies plasma lipid profile and paraoxonase has an antiatherogenic property. Non-selective beta-blockers affect plasma lipid profile too, but they have atherogenic property when patients take these drugs in long term. In this study the effect of propranolol, a non-selective beta-blocker, on paraoxonase activity was investigated. L...
