In the present paper, a multi-unit redundant system with unreliable, repairable units is considered. Two types of maintenance operations - the replacement of the failed main unit by the redundant one and the repair of the failed unit - are performed. The case of the system with one replacement server with arbitrary replacement time distribution function and repair server with an exponential distribution of repair time is considered. For this system mixed-type semi-Markov queuing model with the bifurcation of arrivals is constructed. It represents a non-classical boundary value problem of mathematical physics with non-local boundary conditions.

Generalizing the result of D. Kazacos for two hypotheses we consider the ternary detection problem of the Neyman-Pearson type under mismatch. For the case of independent identically distributed observations the sufficiency condition of existence of test with an exponentially dicreasing probability of error is formulated in terms of the new notion of “divergence for three distributions in certain order”.

The basic wiretap channel model is considered. The aim is to maximize the rate of the reliable communication from the source to the legitimate receiver, while keeping the confidential information as secret as possible from the wiretapper (eavesdroper). The E-capacity - equivocation region, which is the generalization of the capacity - equivocation region, is investigated. The outer bound of this region is constructed.

In the present work is considered an approach, according to which canonically conjugate colors in the theory of fuzzy sets are related to the properties of information functions and non-commutative linear operators in Gilbert’s space: each information state corresponds to the estimation of compatibility function, every color – to the operator.It is supposed that color, as some property (attribute), characterizing a condition of a system, can receive different values called by eigenvalues of this color. The cases of discrete and continuous spectrum of eigenvalues of color are considered. The example of calculation of conditional computable values of color is given.

Let us adduce some definitions. If A is a nonrecursive computably enumerable (c.e.) set, then a splitting of A is a pair A1, A2 of disjoint c.e. sets such that A1 U A2 = A.A c.e. set A is T-mitotic (wtt-mitotic) if there is a splitting A1, A2 of A such that A1 ≡T A2≡T A (A1 ≡wtt A2≡wtt A).In this article it is proved, that there exists a low c.e. degree u such that if v is a c.e. degree and u ≤ v, then v contains a hypersimple T-mitotic set, which is not wtt-mitotic.
让我们引证一些定义。如果A是一个nonrecursive可计算的枚举(公元)组,然后分裂的是一对A1, A2的着力点的A1 U A2 =一位刚建成时设置一个T-mitotic (wtt-mitotic)如果有分裂A1, A2的(A1, A2≡≡T T (A1≡≡wtt A2 wtt)。本文证明,存在一个低石球学位你这样如果v是一个石球程度和U≤v, v包含hypersimple T-mitotic集,这不是wtt-mitotic。

This paper presents an end-to-end test solution for an automotive system on chips (SoCs). The presented multipurpose solution provides the possibility to select the appropriate test mechanisms at design stage, detect manufacturing faults during the production, check the safety mechanisms during power-up, as well as run periodic test during mission mode. A software automation tool and its application to a safety critical SoC are demonstrated to show the effectiveness and completeness of the proposed flow.

Data Lake is a technology that became very popular because Big Data is a part of modern reality. However, modern databases often do not fit the data that organizations want to store because of various reasons. When should people think about using Data Lakes? In what cases can Data Lakes be used, and when will their use bring some benefits to companies? We introduce the Data Lake view to Big Data processing. We present a new approach to distributed Database System and we propose to use some effective Data tools for databases management. In this article, we analyze how to use this technology, discuss the prospects and possible problems in the implementation of Data Lakes in practice.
