Probing effective slippage on superhydrophobic stripes by atomic force microscopy
Soft Matter, 2016While the effective slippage of water past superhydrophobic surfaces has been studied over a decade, theoretical predictions have never been properly confirmed by experiments. Here we measure a drag force on a sphere approaching a plane decorated by superhydrophobic grooves and compare the results with the predictions of semi-analytical theory ...

Optimization of transmission towers considering the bolt slippage effect
Engineering Structures, 2020Abstract In a previous contribution (de Souza et al., 2016), the authors proposed a flexible approach for the optimization of self-supporting transmission line towers (TLT). The scheme takes into account constructional and structural features to allow a direct industrial application. For instance, according to CIGRE (2009), de Souza et al.

Gas Slippage in Two-Phase Flow and the Effect of Temperature
Proceedings of SPE Western Regional Meeting, 2001Abstract Gas slippage in single-phase gas flow (Klinkenberg Effect) has been investigated extensively. Few papers, however, have been published on the gas slippage in gas-liquid two-phase flow. The gas relative permeabilities at water saturations close to the residual value have been found to be significantly greater than one in both ...

Slippage Effects of the Conservation Reserve Program: Reply
American Journal of Agricultural Economics, 2005AbstractGiven that the Conservation Reserve Program (CRP) costs taxpayers $2 billion per year and remains the largest conservation program in U.S. history, Roberts and Bucholtz are to be commended for revisiting the slippage issue. However, their central point that regional variation in CRP acreage is endogenous is inconsistent with CRP implementation ...

Effect of Bolt Slippage on the Static Response of Lattice Structure
Applied Mechanics and Materials, 2013Bolted connection technology has been widely used in steel structure engineering. Conventional structural analysis softwares solve related problems with the assumption of regarding the bolted connection as a rigid joint connection. Thus the calculated internal forces of the structure members are bigger than those of real measurements, and the ...

Air pressure in tires effects on slippage of tractors [PDF]
, 2015 Traction features of the tractor depend on the dynamic rates of the engine and transmission parameters. The traction features of the tractor depend greatly on the driving wheel exploitation characteristics, the physical-mechanical properties of the soil, and on the interaction of the driving wheels and the soil.

Drainage of a Wetting Liquid: Effective Slippage or Polymer Depletion?
Tribology Letters, 2008A surface force apparatus has been used to investigate the drainage of a viscosity improver lubricant. The characterization of the VI confined interface has been performed. Surprisingly, dynamical measurements enlighten a significant negative value of the immobile layer thickness.

Theoretical prediction of hydrodynamic effect by tailored boundary slippage
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2006Classical sliding bearings usually rely on the converging geometrical wedge to generate desirable hydrodynamic lubricating effects. This article proposes a novel approach to the generation of efficient hydrodynamic effects in sliding bearings, including those running without the apparently indispensable geometrical wedge.

The effects of slippage and diffraction in long wavelength operation of a free electron laser
International Journal of Infrared and Millimeter Waves, 1995The Free-Electron Laser user facility FELIX produces picosecond optical pulses in the wavelength range of 5–110μm. The proposed installation of a new undulator with a larger magnetic period would allow extension towards considerably longer wavelengths.
