Physical mechanisms and models of long-term transformations of radiative recombination in n-GaAs due to the magnetic field treatments

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2016
Simulation of long-time changes in photoluminescence of n-GaAs has been performed, and the mechanism of transformation of the defect structure caused by magnetic field treatments has been represented.

Simplicial Random Variables

open access: yes, 2017
We introduce a new `geometric realization' of an (abstract) simplicial complex, inspired by probability theory. This space (and its completion) is a metric space, which has the right (weak) homotopy type, and which can be compared with the usual geometric realization through a natural map, which has probabilistic meaning : it associates to a random ...

Estimation of the two-parameter Weibull distribution parameters using the coefficient of variation

open access: yesVojnotehnički Glasnik, 1996
This paper presents a method for estimating the reliability function parameters when reliability function is the 2-parametar Weibull regression. This model is often used in a reliability analysis in wide variety of situations to approximate successfully ...

Dimensions of random affine code tree fractals

open access: yes, 2012
We calculate the almost sure Hausdorff dimension for a general class of random affine planar code tree fractals. The set of probability measures describing the randomness includes natural measures in random $V$-variable and homogeneous Markov ...

Еstimation of randomity of generators of keys of the crypto system

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
The aim of the study is to develop an algorithm for constructing an integer random variable representing random components of the keys of the RSA cryptosystem, and determining the table for the distribution of its probabilities.

Multi-type branching processes with time dependent branching rates

open access: yes, 2018
Under mild non-degeneracy assumptions on branching rates in each generation, we provide a criterion for almost-sure extinction of a multi-type branching process with time-dependent branching rates.

Variable selection in multiple regression with random design

open access: yes, 2015
We propose a method for variable selection in multiple regression with random predictors. This method is based on a criterion that permits to reduce the variable selection problem to a problem of estimating suitable permutation and dimensionality.
