Effect of Ferrous Alloy Type, Beetroot Juice, Deicer Type and Concentration on Early-Stage Corrosion Behavior of Buried Pipes
Publisher: ASCE
Abstract: In this laboratory study, the corrosion behavior of ASTM A1008 CS Type B carbon steel (C1008), ASTM A48 Class 35 gray cast iron (GCCL35), and ASTM A536 65-45-12 ductile cast iron [Ductile(65-45-12)] was examined in a ...
Galloping Suppression of Iced Transmission Lines by Viscoelastic-Damping Interphase Spacers
Publisher: ASCE
Abstract: Galloping of iced conductors is a kind of self-excited aeroelastic vibration at low frequency and large amplitude causing various damage to transmission tower-line systems. This paper proposes viscoelastic-damping interphase ...
Dynamic States Recognition of Friction Noise in the Wear Process Based on Moving Cut Data-Approximate Entropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wear experiments are performed to explore dynamic states changes of friction noise signals. A new characteristic parameter, moving cut data-approximate entropy (MC-ApEn), is adopted to quantitatively recognize dynamic ...
Galloping Stability Criterion for 3-DOF Coupled Motion of an Ice-Accreted Conductor
Publisher: ASCE
Abstract: This study presents an analytical galloping stability criterion for a three-degree-of-freedom (3-DOF) coupled motion of an ice-accreted conductor by using the eigenvalue perturbation method. To compare the validity of this ...
A Study on Methods for Determining Phase Space Reconstruction Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several pairs of algorithms were used to determine the phase space reconstruction parameters to analyze the dynamic characteristics of chaotic time series. The reconstructed phase trajectories were compared with the original ...
Polyvinylchloride Ultrafiltration Membranes Modified with Different SiO2 Particles and Their Antifouling Mechanism for Oil Extraction Wastewater
Publisher: American Society of Civil Engineers
Abstract: Novel low-cost and antifouling polyvinylchloride (PVC)–based membranes were fabricated with regular and hydrophilic nano-
Observed Variations of the Atmospheric Boundary Layer and Stratocumulus over a Warm Eddy in the Kuroshio Extension
Publisher: American Meteorological Society
Abstract: AbstractA research vessel sailing across a warm eddy in the Kuroshio Extension on 13 April 2016 captured an abrupt development of stratocumulus under synoptic high pressure. Shipboard observations and results from regional ...
