Tracer diffusion is one of most reliable techniques for providing basic kinetic data in solids. In the present review, selected direct methods, particular radiotracer measurements as a superior technique due to its high sensitivity, Secondary-Ion-Mass-Spectroscopy (SIMS) profiling, X-Ray Diffraction and Rutherford Backscattering Spectrometry are presented discussed. Special attention put on describing currently used sectioning detail with focus experimental applications complications. The...
This study aims to characterise a composite material from compressed earth reinforced with corn husks fibers. In order achieve this objective, the work started by conducting many laboratory tests on fibers and soils. The parameters that were determined included diameters, stress at rupture, elongation deformation Young modulus 1 2, constraint maximum for addition, geotechnical of soils determined, including water limit liquid, plastic liquid also determine optimal moisture soil is dry...

Equipment digitization of material transition allows you to get real-time slice economically important indicators. Also, the whole dynamics production functionality can be presented in formal view by mathematical models. The article deals with transference linear commercial networks, which are network-like diffusive phenomena described classical equations physics. In...
Three-dimensional attainability set “at instant” for a non-linear controlled system is studied, which often called the “Dubins car”. A object moves in plane. It has linear velocity of constant magnitude and bounded turn radius. The case explored when can to one side only. Moreover, rectilinear motion prohibited by constraints onto control. We prove that sections planes orthogonal angle coordinate are convex. geometric structure these analyzed.
The Dubins car is a model of motion, in which the scalar control u determines instantaneous angular speed rotation.The paper considers symmetric variant constraints u∈[u 1 ,u 2 ], where = -u and 1.We study three-dimensional reachable set at given instant t f > 0.

A three-dimensional reachable set "at the instant" for a controlled object called Dubins car is considered. The turn angular velocity of linear vector control variable. Along with case when, according to statement problem, rotation possible in both directions, cases one-sided are studied. Three-dimensional images sets presented. Sufficiency Pontryagin maximum principle conditions leading boundary analyzed. Possibility using problem motion observation under inaccurate measurements geometric position
A brief review of experimental data on the effect exerted by both constant and pulse magnetic field upon heterodiffusion in powders, polycrystalline monocrystalline ferromagnetic metals alloys is presented paper order to analyze regularities mechanisms initiation numerous phenomena covered single term “magneto-diffusion effect”. The most probable influence diffusion processes are analyzed.
The effect of additives diamond powders different dispersity on properties bronze-based abrasive composites is researched. A standard bond tin bronze M1 (20% tin, 80% copper) with 1–4 wt % natural 3/2 and 7/5 µm ultradispersed powder used. It was found that addition particles in the amount 1–3% to metal matrix has a positive physical, mechanical performance composite materials.
In mathematical control theory, a Dubins car is nonlinear motion model described by differential relations, in which the scalar determines instantaneous angular rate of rotation. The value linear velocity assumed to be constant. phase vector system three-dimensional. It includes two coordinates geometric position and one coordinate having meaning angle inclination vector. This popular used various tasks related an aircraft horizontal plane, with simplified description car, small surface...
The analysis of the conditions for emergence steady-state modes continuous media transportation process leads to search stabilization flow phenomena in network carriers – it is essential know change quantitative characteristics mathematical model with an unlimited time variable. Such based, first all, on study properties model's stability sufficiently small changes initial data when variable tends infinity. At same time, opportunities build a stabilizing control effect case its instability...
The impact of a pulsed magnetic field on Sn diffusion in α-Fe is investigated within the intensity range 79.6–398.0 kА/m and frequency 1–21 Hz at 730, 740, 750 °С. solute coefficients were measured by X-ray diffraction analysis. was found to influence significantly α-Fe. A resonant maximum bulk coefficient observed 13 398.0 kА/m. Possible mechanisms established magneto-diffusion coupling are discussed.
One of the fundamental indicators that characterize state socio-economic situation in region is quality life population. To this end, it necessary to analyze and evaluate volume consumption goods per capita, as well logistics component development consumer market. The article considers impact trade infrastructure market its constituent elements on population Irkutsk region. analysis main factors affecting standard living given. Ways improve are proposed.
We describe the algorithm for recovering an aircraft trajectory that is based on construction of a bundle trajectories, which are most possible versions real motion.
