Enhancement of wear properties of a polyether ether ketone polymer by incorporation of carbon and glass fibers [PDF]
, 2019 Some properties of polymers can be improved through the incorporation of carbon and glass fibers into the polymer matrix. In this research, the wear resistance of two polymer composites CF-polyether ether ketone (PEEK) and GF-PEEK were compared with the ...

Clinical consequences of changing the sliding window IMRT dose rate [PDF]
Journal of Applied Clinical Medical Physics, 2012 Changing pulse repetition frequency or dose rate used for IMRT treatments can alter the number of monitor units (MUs) and the time required to deliver a plan. This work was done to develop a practical picture of the magnitude of these changes. We used Varian's Eclipse Treatment Planning System to calculate the number of MUs and beam‐on times for a ...

Frictional sliding tests on combined coal-rock samples
Journal of Rock Mechanics and Geotechnical Engineering, 2014 A test system was developed to understand the sliding mechanism of coal-rock structure. The test system was composed by a double-shear testing model and an acousto-optic monitoring system in association with a digital camera and an acoustic emission (AE)

Generalized Gray Codes for Local Rank Modulation [PDF]
, 2011 We consider the local rank-modulation scheme in which a sliding window going over a sequence of real-valued variables induces a sequence of permutations.

A dissolution-diffusion sliding model for soft rock grains with hydro-mechanical effect
Journal of Rock Mechanics and Geotechnical Engineering, 2018 The deformation and failure of soft rock affected by hydro-mechanical (HM) effect are one of the most concerns in geotechnical engineering, which are basically attributed to the grain sliding of soft rock.

Melting-freezing cycles in a relatively sheared pair of crystalline monolayers [PDF]
, 2002 The nonequilibrium dynamical behaviour that arises when two ordered two-dimensional monolayers of particles are sheared over each other is studied in Brownian dynamics simulations.

On the Growth Rate of Tribomaterial in Bovine Serum Lubricated Sliding Contacts [PDF]
Lubricants, 2016 Considering total hip arthroplasty, so-called tribolayers (aka tribomaterial), consist of carbonaceous material from the periprosthetic joint fluid or bovine serum mixed with nanometer size metal and oxide wear particles. Currently, its growth sequence and rate are unknown. Thus, smooth surfaces of low-Carbon (LC-) vs.

ANTISEIZURE CHARACTERISTICS OF LEADED ALUMINUM ALLOYS UNDER DRY SLIDING CONDITIONS
Journal of Engineering, 2010 Aluminum-Silicon alloys, with soft lubricant metal, are considered to be one of the important tribological alloys which resist seizure. The effect of different lead percentages (1-20%Pb) that added to the modified eutectic Al-12%Si alloy on the wear ...
