Hysteresis of the shape of a finite magnetic fluid volume in axisymmetric magnetic fields
In this paper the behavior of a finite magnetic fluid volume on a line conductor is investigated. Here we consider the problem of a magnetic fluid drop on a line conductor and the problem of a finite magnetic fluid volume on a horizontal plane near a vertical line conductor. The possibility of the fluid shape hysteresis for a cyclic increase and decrease of the current and of spasmodic drop thickness changes at certain values of the current is treated.
In this paper the behavior (break-up and creation) of a magnetic fluid bridge between two coaxial cylinders in a magnetic field of a line
conductor for any values of wetting angles of a magnetic fluid is investigated.
The Hamiltonian description of ferrohydrodynamics equation for a ideal nonconducting compressible magnetic fluid with frozen-in magnetization is presented.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
