Measurement of the dielectric constant of highly absorbing polar liquids at microwave frequencies

Nomograms are given for claculating the dielectric constant and dielectric loss of polar liquids by measuring the standing wave ratio for an infinitely thick layer of fluid and the layer thickness at which wave reflection is minimum.

On methods of defuzzification of parametrically represented fuzzy numbers

A comparative analysis of such methods of defuzzification of fuzzy numbers as WABL (Weighted Averaging Based on Levels), centroid, and mean of maxima (MOM) is presented in the study. Analytic formulas are presented for calculating the defuzzification values for parametrically represented fuzzy numbers of triangular and trapezoidal form.     

Cobalt diffusion during doping of ZnSe single crystals

Cobalt diffusion into single crystals of the compound semiconductor ZnSe has been studied under the conditions of the S _ZnSe-S _CoSe-L _Zn-V phase equilibrium at temperatures from 700 to 970°C, and the diffusion coefficients of cobalt in (100)-and (111)-oriented single-crystal samples of zinc selenide have been determined as functions of temperature. The diffusion rate of cobalt along the [111] direction is shown to exceed that along [100].     

Controlled rolling with intermediate recrystallization of type St3sp steel

Conclusions A promising variation of strengthening of type St3sp steel is thermomechanical treatment, controlled rolling with intermediate recrystallization. With it the strength of the steel increases by 95–200 N/mm², the 50% ductile-to-brittle transition temperature drops by 60°C, and the work for crack development doubles in comparison with these properties of steel in the hot rolled condition.I.

Aggregation of Fuzzy Information on the Basis of Decompositional Representation

This paper deals with the problem of defuzzification of a fuzzy number on the basis of decompositional representation that takes into account the strategy of making decisions by a decision-maker (DM). Some advantages of this approach are shown and a method is proposed that increases the level of preciseness of the averaged representative of a fuzzy number with the help of changing weight coefficients of level sets.This work is supported by the TUBITAK NATO PC-B Program.__________Translated from Kibernetika i Sistemnyi Analiz.
