Investigation of the force effect of the vibrating working body of the slitter on the soil [PDF]

E3S Web of Conferences, 2020
The theory of the force action of the working body of the slitter on the ground is considered. It is proposed to divide this force into four components: the force of cutting the material, the force of overcoming the friction forces acting on the ground ...

Quantum Metallicity on the High-Field Side of the Superconductor-Insulator Transition [PDF]

, 2007
We investigate ultrathin superconducting TiN films, which are very close to the localization threshold. Perpendicular magnetic field drives the films from the superconducting to an insulating state, with very high resistance.

Bearing resistance property of diameter-expanded anchorage in sandy ground [PDF]

E3S Web of Conferences, 2019
Based on a past centrifugal model test and complementary discrete element method (DEM) simulation, this paper provides insights into bearing resistance of diameter-expanded anchorage with its anchor body expanded. In the centrifugal model test, an anchor

Electron interaction-driven insulating ground state in Bi2Se3 topological insulators in the two dimensional limit

, 2010
We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from one quintuple layer to six quintuple layers grown by molecular beam epitaxy.

Testing and analysis of corrected specific frictional resistance in the ground heat exchanger with water as heat-transfer fluid

Case Studies in Thermal Engineering, 2023
As the scale of a ground-coupled heat pump system increases, the proportion of energy consumed by the conveying system increases. It is crucial to obtain an accurate specific frictional resistance in the ground heat exchanger (GHE) to facilitate a more ...

Strong reduction of ac losses in a superconductor strip located between superconducting ground plates

, 2003
The problem of calculating the ac losses in a superconductor strip with a transport current placed inside superconducting environments is studied analytically in the frame of the critical state model.
