Sensitometric characteristics of an all‐solid‐state photoelectrochromic pixel for an electrochromic light‐addressable display

Abstract— An all solid‐state photoelectrochromic element (PECE) was developed on the basis of electrochromic layers of WO₃ and polyaniline with a layer of polymer electrolyte placed on a base of polyamidosulfoacid, in which a thin‐film CdS_xSe_1?x photoresistor was used as an electronic key. The dependence of the sensitometric characteristics of the PECE on the applied voltage was studied.     

Probability-Theoretic and Statistical Analysis of Dictionary Texts

We consider probability-theoretic and statistical models and methods for computing the characteristics of dictionary structures. Results of a statistical analysis of several commonly used dictionaries are presented in order to test the adequacy of the computing methods proposed.     

Increasing the precision of a device used to determine the dynamic coefficient of friction

A theoretical evaluation of the potential application of a device with inclined plane for determining the dynamic coefficient of friction is given. Structural changes in the device that make it possible to increase its precision are proposed. Computational equations for estimating the resolution of the device are presented. __________ Translated from Izmeritel’naya Tekhnika, No. 11, pp. 24–26, November, 2007.     

Modeling of phase transitions of the first kind by the method of integral equations in the case of a stationary moving surface source

The procedure for solving the Stefan problem by reducing it to a nonlinear integral equation of minimum dimensionality is described in brief. Examples of modeling the phase transitions are given when a half space and a metal layer are subjected to the thermal action of a stationary uniformly moving surface source of electric-arc origin.Notation x abscissa - y ordinate - z third coordinate - t time - v velocity - u absolute temperature - thermal conductivity - mass density - c heat capacity - latent heat of the phase transition - u _i temperature of the phase transition - Heaviside unit function - M point of the three-dimensional space - q _s density of the surface source - f density of the bulk source - r _M,N distance between the pointsM andN - polar angle - P arc power - h thickness of the metal layer - m number of nodes of the finite-difference scheme - n number of the iteration Novocherkassk Polytechnic Institute.

Modeling turbulent flow at a permeable plate with strong injection

It is shown that available experimental data on the thickness of the turbulent-boundary layer and the filling of the velocity profile under strong injection are satisfactorily generalized using the parameter _wv²w/ ₀u ₀ ² .Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 34, No. 1, pp. 94–98, January, 1978.     

Molecular dynamics simulation of the melting of uranium dioxide nanocrystals

The melting of vacuum-isolated uranium dioxide (UO₂) nanocrystals is studied by molecular dynamics simulation using the approximation of pair potentials and point ions. The size dependences of the melting temperature, the heat of melting, and the density jump of cubic crystals up to 1000 nm³ in size are measured for the ten most relevant sets of pair potentials. The linear and parabolic extrapolations of these dependences to macroscopic sizes are considered, and the parabolic extrapolation is found to be better for analyzing data on the melting temperature and heat.     

Production of mineral binder from steel-smelting slag

The phase composition of steel-smelting slag may be processed to obtain mineral binder. Gypsumbased binder has been produced on the basis of refining slag from the ladle–furnace unit. Hydraulic-binder clinker may be obtained on the basis of steel-smelting slag. The possibility of processing such slag to obtain mineral binder is demonstrated.
