Some Improvements in Elastoplastic Friction Compensator

SICE Journal of Control, Measurement, and System Integration, 2017
For robotic joints with compliant transmissions, Mahvash and Okamura have proposed a friction compensator based on an elastoplastic friction model. One drawback of the compensator is that the compensator continues producing non-zero output force in the ...

Comparison of Friction in Sliding Mechanics Using Different Ligation Methods on Ceramic Bracket with Metal Slot and Epoxy Resin-Coated Stainless Steel Esthetic Wire: An in Vitro Study

Journal of Indian Orthodontic Society, 2019
Introduction: The friction generated during orthodontic treatment seems of concern in terms of anchorage and treatment duration. Different ligation methods have been developed to reduce the friction as compared with regular elastic modules.

The Static Frictional Behaviors of Rubber for Pipe-Laying Operation

Applied Sciences, 2017
Experimental research is carried out to reveal the static frictional behaviors of rubber pipe contact systems. This research is motivated by deep water pipe-laying operations where rubber blocks are used to clamp the pipe to supply sufficient static ...

Static and Dry Friction due to Multiscale Surface Roughness

, 2008
It is shown on the basis of scaling arguments that a disordered interface between two elastic solids will quite generally exhibit static and "dry friction" (i.e., kinetic friction which does not vanish as the sliding velocity approaches zero), because of

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
