Self-Testing Checker Design for arbitrary number of code words of (m,n) code

FPGA technology is used to provide self-testing checker (STC) design based on ability of each LUT to implement any Boolean function of the fixed number of variables and applying two outputs CLBs consisting of two LUTs. A universal decomposition synthesis method of STC for subset of all code words (arbitrary number L of code words) of (m,n) code is suggested. It is based on separating the proper essential subtrees from the tree representing all code words of (m,n) code. Self-testing property is proved for a set V of faults including multiple stuck-at faults at each CLB input and output poles. As a rule complexity of a self-testing checker for an arbitrary number of code words of (m, n) code is less than complexity of a self-testing checker for all code words of the same (m, n) code

Investigation of the reaction D(

The cross section of the reaction D(4He, γ)6Li with titanium and zirconium deuterides as targets is measured for incident 4He+ ion energies of 30 and 36 keV, respectively. The ion beam is generated by a Hall pulsed plasma accelerator. For the first time, upper limits on the cross section of the reaction D(4He, γ)6Li at ultralow energies are imposed (at 90% confidence level): σ ≤ 1.2 × 10−35 cm2 for the TiD2 target and E(4He+) = 30 keV, and σ ≤ 7 × 10−36 cm2 for the ZrD2 target and E(4He+) = 36 keV

In this study, problems of statistical simulation of acoustic radiation propagation in the lower atmosphere along the vertical and horizontal paths by the Monte Carlo method and construction of the acoustic model of the atmosphere are considered. The influence of the geometry of problem being solved, radiation frequency, angle of source divergence, and outer scale of turbulence on the transmitted radiation intensity is discussed with allowance for the contribution of multiply scattered radiation.

Time distribution of the monostatic sodar signal intensity has been obtained in the report with allowance for the contribution of multiply scattered radiation. Dependences of the sodar signal intensity on its parameters and atmospheric meteorological conditions are analyzed.

The Monte Carlo method is first used to estimate the contribution of multiple scattering to signals of a monostatic sodar operating in plane-stratified turbulent atmosphere. Numerical estimates of multiple scattering contributions are presented as functions of the sodar parameters, and atmospheric conditions.

Li at ultralow energies

In the present work, the problem of propagation of monochromatic acoustic radiation in the lower 500-meter layer of the plain stratified moving turbulent atmosphere is solved by the Monte Carlo method. The influence of the parameters of models of the outer scales of temperature and dynamic turbulence on the intensity of transmitted acoustic radiation intensity is investigated.

Statistical simulation of acoustic radiation propagation in the lower atmosphere by the Monte Carlo method

A detection instant problem of the GARCH-process parametric change with random noise distribution is studied. A sequential procedure of imbalance instant detection, where a decision of change existence is made at a given instant of time after the accumulation of given distinctions between possible process models, is suggested. Formulas for procedure characteristics calculation are developed, asymptotic qualities of the procedure are studied. Model estimated values are presented.
