The present paper deals with an original 2D modeling of mechanical state of ball bearings in dynamic mode using the Discrete Element Method (DEM). An electromechanical coupling is introduced to extract an electrical and measurable response of a beari

We are on the cusp of a technological revolution that will fundamentally change our relationships to others and the way we live and work. These changes, in their importance, scope, and complexity, is different than what humanity has known until now.

We have developped an original 2D modeling of bearings by Discrete Element Method (DEM). The mechanical behavior and the dynamic of a bearing is well reproduced. An electromechanical coupling is introduced to provide monitoring solutions. In practice

We study numerically and theoretically the electrical behavior of individual steel beads and the contact between 2 adjacent beads within a granular system. Due to the thin insulating oxide layer present at the surface of the beads, the coupling betwe

We performed electrooptical measurements in the smectic-Cα* (SmCα*) phase of the antiferroelectric liquid crystal, 4-(1-methyl-heptyloxycarbonyl)phenyl 4-octylcarbonyloxybiphenyl-4-carboxylate (MHPOCBC), and showed that the frequency dispersion of

We have experimentally investigated the electric-field effect on the Isotropic - B 2 phase transition of an achiral banana-shaped mesogen 1,3-phenyllene bis[4-(4-10-alkoxy-benoyloxy)phenyliminomethyl] ( C 11 compound) [1]. From microscopic observatio

Electro-optical measurements have been performed around the SmA-SmCα*phase transition point in antiferroelectric liquid crystals MHPOBC and MHPOCBC. In both materials the soft mode condensation is clearly seen in addition to the partial softening of

We have performed precise measurements of the third-order dielectric constant in an antifer-roelectric crystal MHPOCBC. In the vicinity of the SmA- SmCα* phase transition point an anomalous increase of it was observed. We have developed a Landau the

In the SmC* phase of AFLC in planar geometry, a new contribution to the electro-optical response was found. This mode which we propose to be called a “surface layer mode”, appears with the occurrence of 2π-disclinations in the texture. Some evid
