 O.N. Karavashkina and S.B. Karavashkin SOME ASPECTS OF THE EARTH EVOLUTION. CHAPTER 2. HYPOTHESIS OF ORIGIN OF PLANETARY SYSTEM (PART II)

Published on 27.01.2005

In this portion of work we study, which part the dynamic electric field takes in formation of galactic structures in the course of their evolution. We show definitive effect of this field on substance concentration in galactic spiral arms as the medium of star formation and the part of dynamic electric field of the star itself in the star's structure and evolution. In this portion of Chapter 2 we also consider chemical evolution of stars and show nucleosynthesis to be not confined to the stage of iron synthesis, but progressing up to those chemical elements which are able to remain stable under conditions in the particular star.

Keywords: cosmogony, cosmology, electric field of young star, formation of magnetic field of star, formation of the star structure, mechanism of star rotation, mechanism of infra-low-frequency oscillations in the star.

S.B. Karavashkin and O.N. Karavashkina. ON LONGITUDINAL EXCITATION OF ELASTIC MEDIUM HAVING A MOVING BOUNDARY

Published on 06.02.2005

In these notes we are studying two most typical models of a wide class of problems on longitudinal excitation propagating in an ideal elastic medium having a moving ideally reflecting boundary. These problems have most broad area of applications, from mechanics to fundamentals of Relativity and electromagnetism. We showed that in both models the pattern of oscillations is described by progressive waves modulated in amplitude. With it, in case of stationary source and moving boundary, the wave propagation velocity is proportional to the speed of boundary motion, and in case of synchronous shift of the source and boundary, the conditions of modulation essentially depend on the shift velocity. Besides, we present the technique to transmit non-distorted measures of space and time between mutually moving reference systems.

Keywords: physics, dynamics of elastic systems, oscillations in elastic media with a moving boundary, techniques to transmit the spatial and temporal measures between mutually moving reference frames

  Dyna P. Karavashkina  and S.B. Karavashkin PHENOMENA AT ELECTRIC CONTACTS BREAKING DIRECT-CURRENT INDUCTIVE LOADS

Published on 08.03.2005

This paper is devoted to theoretical and experimental study of physical nature of unstable discharges arising in contact gaps when opening inductive load. We revealed that despite conventional opinion, showering arcs are alternating relaxations. Each of them consists of two stages: monotonous exponential growth of voltage related to the charging of parasitic capacitance of gap which is shunted by metallic bridges, and of high-frequency high-voltage oscillation process related to the high-frequency spark process within the gap. With it, metallic bridges are produced in each period of unstable discharges. We analyse the conditions and stipulate the physics of processes of such bridges formation. We established that the cause of bridge formation is the electric pressure in high-voltage oscillation process preceding the monotonous period of unstable discharge. The second cause are plasma jets able to strap even larger gaps than those typical for unstable discharges. The experimental results obtained after this theoretical study fully corroborated the described pattern of physical processes in showering arcs. On the basis of developed method to obtain the dynamic curve of breakdown voltage and noting the experimentally corroborated physics of processes, we have successfully carried out the work on practical protection of relay contacts working under inductive load, and presented the result of this protection.

Keywords: contacts opening inductive load, short arcs, unstable discharge, showering discharge, multiple metallic bridges, contact protection from erosion

S.B. Karavashkin and O.N. Karavashkina. ON TRANSVERSE DOPPLER EFFECT IN CLASSICAL FORMALISM

Published on 08.04.2005

On the basis of complete solution of Doppler shift of frequency received by moving receiver, noting non-central motion of receiver as to the source, we compare the properties of longitudinal and transverse Doppler effect predicted by classical and relativistic formalism. We show that complete statement of problem predicts the transverse Doppler effect in frames of classical formalism, but its properties considerably differ from relativistic predictions. In particular, the sign of effect predicted by classical conception is opposite to that relativistic. While just the classical approach is most fully consistent with the phenomenology of effect, while the relativistic approach is essentially problematic both in description of phenomenon and in consistency of functional regularity with the properties of transverse Doppler effect. We show that the main difficulty being the underpinning of relativistic interpretation is Fitzgerald hypothesis on whose basis have been built both Lorentz theory and Einstein's conception of constant speed of light in all inertial reference frames.

Keywords: Special Relativity, Doppler effect, longitudinal Doppler effect, transverse Doppler effect, Michelson- Morley experiment, Fitzgerald hypothesis, phenomenology of time as physical phenomenon

S.B. Karavashkin and O.N. Karavashkina. EXACT SOLUTION FOR THE PROBLEM OF ELASTIC INTERACTION OF THREE AND MORE POINT MASSES IN THE COLLISION THEORY

Published on 27.05.2005

We will put in order the solution for the problem of two bodies in the collision theory and develop this ordered solution for the three-body problem. This development appeared possible when noting that at the moment of n bodies interaction each mass interacts simultaneously both with the rest masses of the considered system and with the local centre of their masses. Due to this, the problem of n bodies can be divided into n two-body problems consisting of the studied body and local centre of masses.

Keywords: theoretical mechanics, collision theory, three-body problem, n-body problem, trajectory of mass centre of the system of bodies
