In this work we have shown that the quality of differences pseudomodest on the input and output of the passive circuit is a consequence of the Tellegen's theorem for the two modes of the passive chain. We proposed measure which characterizes presence

In the present paper, we prove vanishing theorems for the null space of the Lichnerowicz Laplacian acting on symmetric two tensors on complete and closed Riemannian manifolds and further estimate its lowest eigenvalue on closed Riemannian manifolds.

In cloud systems, there is a serious variance in the requirements for the provided resource, as well as there is a need to quickly process incoming requests and maintain the proper level of quality of service - all of these factors cause difficulties

In the present paper, we study the geometry of infinitesimal conformal, affine, projective, and harmonic transformations of complete Riemannian manifolds using the concepts of geometric dynamics and the methods of the modern version of the Bochner te

The model of resource allocation and sharing for conjoint servicing of real time and batched NB IoT trafic streams over LTE cell facilities is constructed. In the model three types of trafic flows are considered. The irst two represent the flows of s

OpenFlow is one of the widely used protocols controller to switch communications in software-defined networking (SDN). The queueing model that capture the communication between single switch and controller is constructed. In the model two types of tr

In the present study, the concentration series of MgAl2O4:Ce3+ ceramics have been fabricated by the Spark Plasma Sintering (SPS) method. Cerium-doping concentration was varied within a range of 0.1–5 wt.%. The prepared ceramics have been tested usi

A complete, simply connected Riemannian manifold of nonpositive sectional curvature is called a Hadamard manifold. In this article, we prove Liouville-type theorems for isometric and harmonic self-diffeomorphisms of Hadamard manifolds, as well as Lio

Gray has presented the invariant orthogonal irreducible decomposition of the space of all covariant tensors of rank 3, obeying only the identities of the gradient of the Ricci tensor. This decomposition introduced the seven classes of Einstein-like m
