Attenuation law of MWD pulses in aerated drilling
Petroleum Exploration and Development, 2012 A mathematical model for predicting the attenuation of measurement while drilling (MWD) pressure pulses in aerated drilling was proposed using the two-phase flow model and considering the momentum and energy exchange at the phase interface, gravity of ...

Sound Propagation in Gas-Vapor-Droplet Suspensions with Evaporation and Nonlinear Particle Relaxation [PDF]
, 2012 The Sound attenuation and dispersion in saturated gas-vapor-droplet mixture in the presence of evaporation has been investigated theoretically. The theory is based on an extension of the work of Davidson to accommodate the effects of nonlinear particle ...

Geophysical Research Letters, 2020 The attenuation coefficient b is one of the most common ways to describe how strong the carbon flux is attenuated throughout the water column. Therefore, b is an essential input variable in many carbon flux and climate models. Marsay et al. (2015, https:/

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

WebLab for Measuring the Attenuation Coefficient of an Optical Fiber [PDF]
Education and Training in Optics and Photonics, 2007 The association of web technology with instrument automation and control has made possible the development of the so called Remote Laboratories or WebLabs — distributed environments that allow to access and control experiments remotely through the Internet — extending the interactivity in virtual learning environments to higher levels.
