An Analytical Solution to Circular Touch Mode Capacitor

In this paper, a simple but accurate analytical solution is presented to model the flexion of a circular diaphragm with clamped edges under an uniform load. The touch down effect and the evolution of touch radius are considered in this model, making it useful for touch down capacitor devices such as pressure sensors. This model is then compared to results obtained from Coventor, a finite elements analysis program designed for microelectromechanical systems     

Quantitative Analysis of Structural Changes in Steel Caused by High-Temperature Holding in Hydrogen

We give a quantitative estimate of changes in the structure of 15Kh2MFA steel after its long-term exposure to the combined action of high temperature, tensile stresses, and hydrogen as the factors of degradation of this steel under conditions of oil hydrocracking. Under laboratory conditions, we study the effect of high-temperature hydrogen degradation of 15Kh2MFA heat-resistant steel on changes in the quantitative characteristics of its structural elements, in particular, in the dimension and average distance between carbides as well as in their orientation from one grain to another. Algorithms for the solution of the formulated problems are described, and the possibilities of proposed approaches for the quantitative automatic processing of metallographic images are shown.

New dust removal equipment for the textile industry

Research and experimental-design studies were conducted to develop a “vortex dust collector— cartridge filter” two-stage unit of the recirculating type. The proposed unit can be effectively used in the textile and other branches of industry. __________ Translated from Khimicheskie Volokna, No. 2, pp. 31–32, March–April, 2006.     

Effect of a convoluted gas flow on the movement of disperse phase in a rotary mass exchanger

The structure of a convoluted gas flow in a rotary mass exchanger is investigated. Profiles of the local-velocity distribution, and experimental functions for their calculation are obtained. A system of differential equations, the solution of which by the Runge-Kutta-Felberg numerical method made it possible to plot the trajectories of moving drops of a disperse liquid in a mass-force field, is compiled. __________ Translated from Khimicheskoe i Neftegazovoe Mashinostroenie, No. 3, pp. 9–10, March, 2007.
