Fractal Fatigue Analysis of Valve Units of Sucker Rod Pumps,PCT), where this fluid flows. The valves are much more susceptible to wear than a sleeve-plunger pair. Therefore, most of the round-trip operations during the well operation are linked to the replacement of valve assemblies.

Book 2016multifractal models of self-similar tribosystems developed on their basis. It provides a comprehensive analysis of their effectiveness, and also considers the method of flicker noise spectroscopy with detailed parameterization of surface roughness friction. All models, problems and solutions are tak

GULF

Fractal Kinetics of Fracture,. are called geometric objects: line, surface, spatial body having very jagged shape, and self-similarity.

Phenothiazines

Multifractal Analysis of Fatigue Failure,Various physical objects and signals even those with self-similarity very rarely can be described with only one value—the fractal dimension. That is why analyses based on the . theory (inhomogeneous fractal objects) have received widespread. The multifractal provides vast new possibilities of fractal analysis for the complex stochastic processes.
