Effect of Strain Rate on the Deformation Characteristic of AlN Ceramics under Scratching

Micromachines, 2021
To clarify the influence mechanism of strain rate effect on deformation characteristics of aluminum nitride (AlN) ceramics, some varied-velocity nanoscratching tests were carried out using a Berkovich indenter in this paper.

Error field penetration and locking to the backward propagating wave [PDF]

Physics of Plasmas, 2015
In this letter, we investigate error field penetration, or locking, behavior in plasmas having stable tearing modes with finite real frequencies ωr in the plasma frame. In particular, we address the fact that locking can drive a significant equilibrium flow.

Using Artificial Neural Network to Predict Rate of Penetration from Dynamic Elastic Properties in Nasiriya Oil Field

Iraqi Journal of Chemical and Petroleum Engineering, 2020
The time spent in drilling ahead is usually a significant portion of total well cost. Drilling is an expensive operation including the cost of equipment and material used during the penetration of rock plus crew efforts in order to finish the well ...

Error concealment using motion field interpolation [PDF]

, 1998
In the context of block-based video coding, two error concealment algorithms are presented. The first algorithm is based on bilinear motion field interpolation (BMFI). For each pel in a damaged block, the algorithm recovers a motion vector using bilinear

Real-time prediction of multivariate ROP (rate of penetration) based on machine learning regression algorithms: Algorithm comparison, model evaluation and parameter analysis

Energy Exploration & Exploitation, 2023
ROP (Rate of Penetration) is a comprehensive indicator of the rock drilling process and how efficiently predicting drilling rates is important to optimize resource allocation, reduce drilling costs and manage drilling hazards.
