The global transportation sector is undergoing a major transformation associated with the transition to a low-carbon economy and the expanded use of alternative energy sources. In recent decades, the substitution of petroleum-based motor fuels with their substitutes – primarily biofuels and electric power (electric vehicles) – in light-duty road transport has accelerated. Public policy at ...

В условиях цифровизации минимизируется влияние негативного человеческого фактора в производственной системе, человек получает возможность заниматься творческой деятельностью, а не рутинной, и трудиться в более комфортных условиях, то есть параллельно с техноцентричностью на производствах формируется человекоцентричность. В ИПУ РАН разработана методология моделирования процесса технологической подготовки гибкого производства всевозможных изделий (включая автоматы) в различных производственных условиях с ...

This article proposes a cross-situational specialization framework for what, at its introduction, was a newer generation personal computer (PC) device (a tablet computer). With use as the basis for continuance adoption as the theoretical lens, this article explores how the tablet coexists as a substitute- and a complement-in-use with incumbent PC(s). To test a model ...

Introduction: Currently, the issues of Internet of Things technology are being actively studied. The operation of a large number of various self-powered sensors is within the framework of a massive machine-type communication scenario, using random access methods. Topical issues in this type of communication are how to reduce the transmission signal power and to increase ...

The current legislation establishes the institution of protection of a good faith purchaser where the compensatory nature of the property acquisition by such purchaser is one of the preconditions for protecting. Currently, in judicial practice, an approach has been adopted, according to which property is considered to be acquired for a fee if the alienator ...

We propose a method for testing the hypothesis about the equivalence of the distribution tail of
observed data and a certain distribution tail, which is the analogue of the goodness-of-fit hypothesis for statistics
of extremes. The method is based on a new data transformation moving k largest order statistics of a
sample from the standard uniform distribution U[0,1] ...

In this paper, we study a generalized construction of (2m, 2m)-functions using monomial and arbitrary m-bit permutations as constituent elements. We investigate the possibility of constructing bijective vectorial Boolean functions (permutations) with specified cryptographic properties that ensure the resistance of encryption algorithms to linear and differential methods of cryptographic analysis. We propose a heuristic algorithm ...

The work is dedicated to the theoretical substantiation of a directed search for 8-bit permutations with given cryptographic properties: differential uniformity and nonlinearity. The statements on the partition of the set of vectorial Boolean functions derived using generalized construction into equivalence classes are proved. The statements that allow one to reject functions from equivalence classes ...

In this paper, we consider checking the robustness of web services using the model of finite state automata and analyzing the solvability of an automaton equation over the concatenation operator. The paper contains the procedure for constructing the largest solution for a solvable automata equation, since a solution to the equation describes a malicious input. ...

The paper studies new ways of con- structing differentially 2δ-uniform bijections over F_{2^{2m}} , m≥3, that are based on TU-construction. Some well known results on the constructing differentially 4-uniform permutations over F_{2^{2m}} are generalized in this work. The core idea is to use TU-construction and differentially δ-uniform bijections to construct 2^t · δ-uniform permutations. A generalized method for constructing 2m-bit differentially 4-uniform permutations ...

Bijective vector Boolean functions (permuta- tions) are used as nonlinear primitives of many symmetric ciphers. In this paper, we study a generalized construction of (2m, 2m)-functions using monomial and arbitrary m-bit per- mutations as constituent elements. A heuristic algorithm for obtaining bijective Boolean functions with given nonlinearity and differential uniformity, based on this construction, is proposed. For ...

Currently, a complete topological classification has been obtained with respect to the topological equivalence of Morse-Smale flows, [9,7], as well as their generalizations of Ω-stable flows on closed surfaces, [4]. Some results on topological conjugacy classification for such systems are also known. In particular, the coincidence of the classes of topological equivalence and conjugacy of ...

Одним из негласных правил создания низкоресурсного блочного шифра стало использование подстановок маленькой размерности. Это обусловлено тем, что такие подстановки хорошо исследованы, требуют небольшого количества ресурсов при аппаратной реализации, и известны эффективные механизмы маскирования, позволяющие защититься от атак по побочным каналам утечки. В то же время, криптографические свойства таких подстановок уступают криптографическим характеристикам подстановок большей размерности.Одним из компромиссов является построение подстановок больших размерностей ...

We say that a graph G has the CIS-property and call it a CIS-graph if every maximal clique and every maximal stable set of G intersects.
By definition, G is a CIS-graph if and only if the complementary graph \(\overline {G}\) is a CIS-graph. Let us substitute a vertex v of a graph G′ by a graph G″ and denote the obtained graph by G. It is also easy to ...
