Foundation of the Power Theory of the Systems and Periodic Multiphase Currents. I

VYNNYCHUK S.D.

ABSTRACT

It is proposed to consider power of the three-phase current as the power of the generator (source) placed in a certain point of the three-phase system. The complete power components have been determined for the symmetric and asymmetric periodic operations.

KEYWORDS

active and reactive power, distortion power, power asymmetry

Moments of Distribution of Error Probability under the Observation of Autocor¬relation Function in the Ideal Channel of Cryptographic Noise-Like Communication System

KOBYAK I.P.

ABSTRACT

Mathematical expectation and dispersion function of probability distribution of the error were determined under observation of the preset pairs of vectors in the sequence of random events. The producing function served as a basis for calculations, it enables to present all the results of a certain class of combinatorial tasks in the form of a sum of n-2 polynomials. Point estimates of autocorrelation function are investigated such as the consistency, unbiasedness, efficiency and sufficiency of selected parameters.

KEYWORDS

elementary events, the variance, the identification of sequences, the probability of missing an error, signature analysis, the generating function.

EVDOKIMOV V. KUCHAEV A. A., PETRUSHENKO E. I., KUCHAEV V. A.

ABSTRACT

A model of three-dimensional magnetic field of the cylindrical electomagnetic stirrer (EMS) based on the scalar system of integral equations (SIE) was obtained as a result of simplification of the vector SIE for magnetization current (MC) on the magnetic circuit surface of the EMS. This system unknowns are projections of density vectors MC which lie in the plane tangential to the magnetic circuit surface.

KEYWORDS

three-dimensional magnetic field, electromagnetic stirrer, magnetic circuit, currents of the magnetization, vector integral equations, integral equations of the scalar system.
