Seismic inversion by hybrid machine learning

, 2021
Full waveform inversion (FWI) has been widely used for recovering a high-resolution subsurface structure from the entire content of measured seismic data. However, FWI requires a good starting model which needs to be close to the true model. If it is not,

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Inversion of multiple geophysical data sets using petrophysical constraints [PDF]

, 2018
The inversion of multiple geophysical datasets co-operatively is a challenge that I address with the fuzzy cluster method. Techniques to incorporate petrophysical constraints and other data in a robust manner in seismic and magnetotelluric inversion were

A Real-Time Interpretation Model for Downhole Pressure of Dual Measuring Points in Managed Pressure Drilling

Shiyou jixie, 2019
Because of the insufficient inversion parameters of the single point measurement data interpretation model, the pressure change cannot be accurately revealed.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.
