Документ Відкритий доступ Calculus: part I. Differential calculus of function of one variable(КПІ ім. Ігоря Сікорського, 2022) Мулик, Олена Василівна; Репета, Леся АнатоліївнаДокумент Відкритий доступ Change in the ellipticity of radiation in magneto-optical crystals under magneto-mechanical resonance conditions(Scientific Collection «InterConf», 2022) Linchevskyi, Igor ValentinovichIt is shown that in magneto-optical crystals with both the Faraday effect and birefringence, it is possible to change the ellipticity of polarized radiation due to a change in the magnetization component parallel to the direction of light propagation. Changes in the ellipticity of the radiation are resonant in the region of frequencies of longitudinal magnetomechanical oscillations of the crystal.Документ Відкритий доступ Chaotic attractors in a deterministic system generator - piezoceramic transducer(UNESP – Campus de São José do Rio Preto, 2007) Krasnopolskaya, T. S.; Shvets, A. Yu.Документ Відкритий доступ Chaotic Oscillations of Nonideal Plane Pendulum Systems(CMSIM, 2012) Shvets, Aleksandr; Makaseyev, AlexanderThe atlas of maps of dynamic regimes of system ”pendulum–electric motor” is constructed. It is established that the deterministic chaos is a typical steady-state regime of the given system. Its class of Feigenbaum universality is defined. The analytical approximation of a Poincare map in a chaotic regime is discovered.Документ Відкритий доступ Complicated Scenarios of Transitions to Deterministic Chaos in Non-Ideal Dynamic Systems(NTU KhPI, 2016) Shvets, Aleksandr Yu.; Sirenko, VasiliySome of non-ideal dynamic systems are considered. It is discovered and described the complicated transition scenarios from regular to chaotic regimes and transitions between different types of chaotic regimes. Described the transition to chaos, which begins by the Feigenbaum scenario, and ends by intermittency. Also discusses the scenario of intermittency with several laminar phases and one turbulent phase. It is discovered and described transitions "hyperchaotic attractor of one type – hyperchaotic attractor of another type," which are realized according to the scenario of a generalized intermittency, but only with two rough-laminar phases.Документ Відкритий доступ Computer and multimedia technologies at practical classes in physics(SWorld &D.A. Tsenov Academy of Economics, 2022) Matvieieva, T. V.; Chursanova, M. V.; Gareeva, F. M.Документ Відкритий доступ Damping of magnetoelastic waves(Bogolyubov Institute for Theoretical Physics, National Academy of Sciences of Ukraine., 2020-10) Bar’yakhtar, Viktor Grigor’evich; Danylevych, Oleksandr GennadiiovychДокумент Відкритий доступ Determination of material constants of magnetostrictive materials(XXI International Scientific and Practical Conference, 2023) Linchevskyi, Igor ValentinovichA mathematical model of a toroidal inductor with a flat ring core made of a polycrystalline magnetostrictive ferromagnet capable of oscillations was developed, as well as a method of measuring the material constants of a polycrystalline ferromagnetic core based on the resonance frequencies of radial oscillations of a ring placed in a toroidal coil. Material constants are understood as a set of the following quantities: components of the tensor of the modulus of elasticity of a demagnetized ferromagnet, components of the tensor of magnetostrictive constants, and components of the tensor of the magnetic permeability of a ferromagnet.Документ Відкритий доступ Differential and Integral Equations(Igor Sikorsky Kyiv Polytechnic Institute, 2022) Kopas, Inna; Zhuravska, GannaДокумент Відкритий доступ Effect of optical vibrations on thermoluminescence of polysilane films and nanocomposites(LLC APF POLYGRAPH SERVICE, 2022) Ostapenko, N.

I.; Kalabukhova, E. N.Документ Відкритий доступ EPR study of paramagnetic centers in SiO2:C:Zn nanocomposites obtained by infiltration of fumed silica with luminescent Zn(acac)2 solution(V. Lashkaryov Institute of Semiconductor Physics, National Academy of Sciences of Ukraine, 2021-06-16) Savchenko, D. V.; Memon, V. S.; Vasin, A. V.; Kysil, D. V.; Rusavsky, A. V.; Kuz, O. P.; Gareeva, F. M.; Kalabukhova, E. N.Документ Відкритий доступ Excitation and distribution of surface of acoustic waves in Z-CUT ZnO single crystals(OSLO, 2021) Linchevskyi, Igor ValentinovichIn this work, for ZnO single crystals, analytical expressions are obtained for the components of the displacement vector of surface acoustic waves (SAW) generated by a single electrode and an interdigital transducer. The dependences of the SAW amplitudes, as well as the change in phase-matching frequencies in ZnO single crystals, depending on the thickness of the metallization layer, are found. The numerical values of such corrections can reach 30 and 20 percent, respectively.Документ Відкритий доступ Existence and Uniqueness of the Solution to the Cauchy Problem for the Stochastic Reaction-Diffusion Differential Equation of Neutral Type(2017) Stanzhytskii, A.

Differential Calculus of a Function of One Variable. Elements of Theory(Igor Sikorsky Kyiv Polytechnic Institute, 2019) Zhuravska, Ganna V.This textbook is designed for students of the first year of technical university. It covers two content areas to be studied in the first semester: Theory of Limits and Differential Calculus of a Function of One Variable. Its content embraces all basic questions on the indicated topics. Each part contains basic mathematical conceptions and explains new mathematical terms. The most important concepts of Calculus are explained and illustrated by figures and examples. The manual contains theoretical material, which presents the basic formulas, definitions and theorems, illustrated by examples and figures, shows the basic methods of solving typical problems. The proposed manual will help students of engineering specialties studying the Differential Calculus of a Function of One Variable.
