This article presents the experimental studies results of the reinforcement effect with polypropylene fiber (0.5 %, 1 %, and 1.5 %) on the strength (compressive cylinder strength) and deformation (compressive strain) ...

Laptinskii, V.N. Construction and Structure Properties of Solutions of a Periodic Boundary Value Problem for a Generalization of the Matrix Lyapunov and Riccati Equations / Laptinskii, V.N., Makovetskaya, O.A. // Differential ...

A method based on the Green’s theorem and the Graph’s addition theorem is used to construct a solution of 2D problem on lateral diffraction of a light beam on a microstructured fiber formed with a finite number system of ...

An vectorial mode solver for microstructured optical fibers based on the representation of the longitudinal components of the mode fields at the interfaces of media in the fiber cross section by Fourier series in angular ...

As a rule, approaches to managing the preparation of learners for programming Olympiads are not intended for intelligent interactive support from learning management and the software tools based on these approaches do not ...

A dust acoustic instability in the cryogenic glow discharge dusty plasma at a buffer gas temperature of 83 K is experimentally investigated. Estimates for the main plasma parameters are given. It is shown that dusty plasma ...

A method is developed for calculating the output characteristics of a drum brake with floating shoes on the basis of the system configuration, the dimensions of the components, the frictional coefficient in contact zones ...

Using the Korteweg–De Vries equation, for background plasma, the distribution functions perturbed by ion-acoustic solitons are calculated. For describing the perturbed distribution functions, the explicit formula is obtained, ...

The object of research is expanded clay concrete reinforced with polymer fiber made of polypropylene. Dispersed reinforcement with polymer fibers is one of the priority directions for modifying lightweight concrete, in ...

This is a theoretical study of the nonequilibrium motion of charged particles in an electric field of solitons. We show that the self-consistent electric field of ion-acoustic and electron-acoustic solitons is characterized ...
