BREAKDOWN INSTANT OF A RANDOM PROCESS
Alexander V. Denisov , Anatoly P. Filimonov
13
Number of inversions of stationary process is shown to be of high informative significance for determination of breakdown instant of stationary operation mode of complex dynamic system. The two criteria are considered: parametric one, associated with representation of variances of elementary harmonic components in canonical decomposition of random narrow-band process as coordinates of a Hilbert space vector, and nonparametric, allowing for process trend extraction under wide prior uncertainty conditions.

Viktor E. Udaltsov, Alina A. Uvarova
67
A physical-mathematical model of LED in TO-1 body is developed. The model parameters are geometric dimensions of LED crystal and body elements, refractive indexes and absorption coefficients of the body material and the crystal. Solution to the problem of light propagation includes taking account of reflection at the body base, cylindrical and spherical dome surfaces, of ray refraction at the surfaces, as well as of light absorption in the crystal and body material. Calculations of polar patterns on the base of the model are compared with experimental results for LED KIPD-21K.
