The regularities of the motion of a onedimensional
FrenkelKontorova dislocation in pure aluminum at helium temperatures are
studied. Computer simulation was carried out using the sine Gordon equation,
written in dimensionless variables. It is proven that when the transition to
dimensionless variables the discreteness of the model is preserved. The dependence
of the true values of stresses on ...

A new type
of bistable spiral waves called “stepped spiral waves”, is investigated in
this study in an oscillatory medium exhibiting perioddoubling bifurcations.
Prior to the perioddoubling bifurcation of this system, the stepped spiral
waves are produced by an unwanted phase trajectory event; the loss of symmetry
takes the form of synchronization defect lines, where the trajectory in the
l ...

The Baryonic TullyFisher
relation was extended to clusters hypothesizing that a_{0}, the characteristic acceleration of the Modified
Newtonian Dynamics (MOND), depends on the mass of the system. Circular speeds
were calculated for systems with mass up to 10^{21} M ...

The impact of the geometry on the gravitational force field and the impact of the mass beyond the test particle location were assessed in the rotation curve calculation of a hypothetical thin disk galaxy using Newtonian and Mondian dynamics. An effective equation for the characteristic acceleration of MOND was obtained based on the Mestel’s finite disk by normalizing the line mass density to the total mass of the galaxy and ...

The longitude of the perihelion advance of Mercury was calculated for the
two and tenbody problem by using a correction to the balance between the force
given by the Newton 2^{nd} law of motion and the Newton gravitational
force. The corresponding system of differential equations was solved
numerically. The correction, that expresses the apparent mass variation with
the body speed, has a trend that is different from those that usually appear in
the electron theory and in the special the...

In this paper we construct conjugate spectral problem and the conditions of biorthogonality for distribution in extended plates of variable thickness of the problem considered. It describes the procedure of solving problems and a numerical result is on wave propagation in an infinitely large plate of variable thickness. Viscous properties of the material are taken into account by means of an integral operator Voltaire. Research is conducted in the framework of the spatial theory of visco elastic...

The
production technology, structure, electrical conductivity, coefficient of friction,
hardness, strength, and plasticity over a temperature range of 290  870 K of laminated coppercarbonic composites for sliding
electrical contacts of currentcollecting devices obtained by electronbeam
evaporation and vapor condensation are studied.
