We deal with rolling contact between quasi-identical bodies. As normal and tangential problems are uncoupled in that case, the simplified approach to determine contact area and normal loading distribution for rolling contact problems is presented in a first part. In the second part, the solution of the tangential problem is used to reactualised the rolling profiles and enables to follow the wea...

Recently Hardcastle & Worrall (2000) analyzed 63 FRII radio galaxies imbedded in the X-ray radiating gas in galaxy clusters and concluded, that pressures inside its lobes seem to be a factor of a few lower than in the surrounding gas. One of explanations of the existing ‘blown up’ radio lobes is the existence of invisible internal pressure component due to energetic cosmic ray nuclei (protons)....

The motion of vortex sheets with surface tension has been analyzed in the setting of irrotational flows by Ambrose [1] and Ambrose and Masmoudi [2] in two dimensions, and by Ambrose and Masmoudi [3] in three dimensions. With irrotationality, the nonlinear Euler equations reduce to Poisson’s equation for the pressure function in the bulk, and the motion of the vortex sheet is decoupled from that...

The article solves the problem of surface gravitational waves using theory tangential discontinuity between media: air-water. Using improved equation mass continuity and taking into account atmosphere inhomogeneity in field Earth, it is shown that during wave processes, these two media mutually influence each other, which explains reason for formation a stormy condition over ocean drop atmosphe...

This paper deals with the handling of deformable linear objects (DLOs), such as hoses, wires or leaf springs, bases on force/torque sensing. First, we describe the characteristic change of force and moment for all single-contact transitions which may occur between DLO and a rigid polyhedron obstacle. Second, we present data processing algorithms for the automated detection of state transitions ...

Abstract The response of the magnetosphere‐ionosphere (MI) system at Jupiter to interplanetary magnetic field (IMF) tangential discontinuity is studied via global Magnetohydrodynamics (MHD) simulations. Our results show that IMF discontinuity, which has a transition front perpendicular Sun‐Jupiter line, strong effects on Jovian MI depending local times and radial distances Jupiter. magnetospher...

The antecedent of this contribution is [1], which constructed the harmonic bidimensional expansions for electrostatic and magnetostatic potentials, produced by a straight line with uniform charge current distributions, respectively, in Cartesian, cylindrical circular, elliptic parabolic coordinates. For successive geometries, sources are confined respective cylinders containing source line, plu...

This paper introduces ‘treatable’ theories, a large class of first-order theories each having a unique countable recursively saturated model.Important examples of such theories are DIS and DLO. It turns out that resplendency or parameter-free resplendency for such theories is implied by a Σ1(Π1 ThN)-statement. Other results concerning resplendency and Σ1definability are obtained.
