GAS PIPELINE PIGABILITY

open access: yes, 2004
In-line inspection equipment is commonly used to examine a large portion of the long distance transmission pipeline system that transports natural gas from well gathering points to local distribution companies. A piece of equipment that is inserted into a pipeline and driven by product flow is called a ''pig''. Using this term as a base, a set of terms

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

A partial discharge detection method for high-voltage cables based on FDTD modeling

open access: yesZhejiang dianli, 2023
The partial discharge (PD) of high-voltage cables and the accessories directly affects the insulation performance of power cables. Therefore, a PD detection method for high-voltage cables based on finite-difference time-domain (FDTD) modeling is proposed.

Leak Detection Methods for Gas Pipelines

open access: yesIFAC Proceedings Volumes, 1986
Abstract The paper describes two methods for detecting and locating leaks in long pipelines. The methods are based on an extended Kalman filter designed by lumping the non-linear Distributed Parameter (DP) system representing the pipeline system using the method of characteristic lines.
