Flow Field and Pressure Loss Characteristics at Rotary Drillstring Joints

open access: yesGeofluids, 2023
A thorough understanding and accurate calculation of the annulus pressure losses are paramount to drilling design and construction. However, due to the influence of the drillstring rotation and the abrupt dimensional variation at the joint, it is ...

Theory completion using inverse entailment [PDF]

open access: yes, 2000
The main real-world applications of Inductive Logic Programming (ILP) to date involve the "Observation Predicate Learning" (OPL) assumption, in which both the examples and hypotheses define the same predicate.

Variants of Plane Diameter Completion [PDF]

open access: yes, 2015
The {\sc Plane Diameter Completion} problem asks, given a plane graph $G$ and a positive integer $d$, if it is a spanning subgraph of a plane graph $H$ that has diameter at most $d$.

Low-Density High-Fluidity High-Strength Epoxy Resin Cement Slurry Technology for Wellbore Reconstruction

open access: yesZuanjingye yu wanjingye
The production rate of a shale gas well generally declines fast, resulting in a low average recovery of the well. Refracturing of an old well with shale gas production pressure depletion can effectively enhance the ultimate recovery of the well, and ...

Concatenated image completion via tensor augmentation and completion

open access: yes, 2016
This paper proposes a novel framework called concatenated image completion via tensor augmentation and completion (ICTAC), which recovers missing entries of color images with high accuracy.

Explanatory completeness

open access: yesActa Psychologica, 2020
All explanations are incomplete descriptions, but reasoners appear willing to assess some explanations as more complete than others. To explain this behavior, we propose a novel theory of the detection of explanatory incompleteness. The account is based on the assumption that reasoners represent explanations as mental models – discrete, iconic ...

Current Status and Trend of Geo-Steering Drilling Technology for Shale Gas Reservoir

open access: yesShiyou jixie
Shale gas resources are strategically vital for ensuring national energy security and achieving the “carbon peak and carbon neutrality” goals. However, shale gas reservoirs in China are generally characterized by low porosity, low permeability and strong

UV completion without symmetry restoration

open access: yes, 2013
We show that it is not possible to UV-complete certain low-energy effective theories with spontaneously broken space-time symmetries by embedding them into linear sigma models, that is, by adding "radial" modes and restoring the broken symmetries.

End-to-end Structure-Aware Convolutional Networks for Knowledge Base Completion [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2018
Knowledge graph embedding has been an active research topic for knowledge base completion, with progressive improvement from the initial TransE, TransH, DistMult et al to the current state-of-the-art ConvE.
