The article provides a detailed analysis of a riveted iron helmet (GIN 148), stored in the Akmola Regional History Museum (ARHM), Kokshetau sity, Republic of Kazakhstan. Initially the helmet was determined as "Russian" by ...

We establish necessary and sufficient conditions for the one-dimensional differential Hardy inequality to hold, including the overdetermined case. The solution is given in terms different from those of the known results. ...

In this paper we use the one-dimensional Schrödinger operator with a negative parameter to the study of the approximation numbers of a hyperbolic type singular operator. Estimates for the distribution function of the ...

In this paper we study the boundedness of convolutions in the anisotropic Lorentz spaces

The article is devoted to the consideration of the development and formation process of the written Turkic languages from the beginning of the XX century. The research is based on the construction of separate lexicology ...

In this paper, a two-hop amplify-and-forward relaying system, where an energy-constrained relay node entirely depends on the energy scavenged from the source signal, is investigated. This paper analyzes the performance of ...

In local terms on finite and infinite intervals we obtain necessary and sufficient conditions for the conjugacy and disconjugacy of the following second order half-linear difference equation Δ(ρi|Δyi|p-2Δyi) + vi|yi+1|p-2yi+1 ...

So far the standard method of prevention of loss of information is a repeated reservation that leads to huge material inputs. Big Data security system developed by authors of the article with an application of the algorithms ...

In this paper we discuss a phase space analysis of various interacting Chaplygin gas models in general relativity. Linear and nonlinear sign changeable interactions are considered. For each case appropriate late time ...

This work is devoted to the study of phase transition processes in nanostructured ceramics of the Y2O3/TiO2-Y2TiO5 type doped with carbon nanotubes as a result of thermal annealing, as well as to the assessment of the ...
