A review of conducting polymers in electrical contact applications

, 1970
A review of recent developments in fretting studies in electrical contacts is presented, focusing on developments in conducting polymer surfaces. Fretting is known to be a major cause of contact deterioration and failure; commonly exhibited as the ...

On the Prospects for African Philosophy in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper grapples with the situation of people of African descent in Australia by working through the constitution of the body of academic philosophy in the country. It contends with the parochialism of the Australian philosophical community and the prospects for the cultivation of greater pluralism. Taking African philosophy as one possible

Mechanism and test analysis of rail corrugation

Journal of Advanced Mechanical Design, Systems, and Manufacturing
In view of the common phenomenon of rail corrugation on subway lines, both field measurement and numerical simulation were used to study mechanism of rail corrugation. In field measurement, vibration signals of vehicles were measured when a train passing

Two‐Dimensional Flow and Thermal Energy Transfer in Non‐Newtonian Casson–Carreau Ternary Hybrid Nanofluids Over Stationary and Moving Wedge Surfaces With Radiation and Magnetic Field Effects

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient thermal management in advanced industrial systems requires improved heat transfer performance, particularly under non‐Newtonian fluid behavior and complex surface geometries. This study investigates the two‐dimensional flow and heat transfer characteristics of ternary hybrid nanofluids over both stationary and moving wedge surfaces ...

Analysis of Stick-Slip Vibration of PDC Bit under Sudden Increase of Formation Hardness

Shiyou jixie, 2019
In drilling an interbedded soft and hard formation with PDC bit, it is prone to cutter crack and damage. To address the issue, the stick-slip vibration characteristics of PDC bit during the sudden increase of formation hardness were studied.

A review of torsional vibration mitigation techniques using active control and machine learning strategies

Petroleum
Drilling is one of the most challenging and expensive processes in hydrocarbon extraction and geothermal well development. Dysfunctions faced during drilling can increase the non-productive time (NPT) greatly, resulting in inflating the drilling cost and

Preparation and Performance Evaluation of a Self‐Generated Particle Plugging Agent Based on Thermosetting Resin

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A thermosetting in situ curing resin microsphere system has been developed. It has controllable phase transition time and particle size. This system addresses the current challenges of low strength, shear susceptibility, and short phase transition time in polymer microsphere blockers and thermoplastic particle blockers.
