Influence of Thread Parameter Errors on the Sealing Property of Tool Joints

Shiyou jixie
In order to investigate the impact of thread parameter limiting errors on the sealing property of tool joints,based on API NC38 tool joint,the existence of three thread parameter limiting errors such as taper,tooth flank angle and pitch were analyzed.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Do stronger intellectual property rights increase international technology transfer? Empirical evidence from U.S. firm-level panel data [PDF]

One of the alleged benefits of the recent global movement to strengthen intellectual property rights (IPRs) is that such reforms accelerate transfers of technology between countries. The paper examines how technology transfer among U.S.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Optimal ownership in joint ventures with contributions of asymmetric partners [PDF]

This paper faces two questions concerning Joint Ventures (JV) agreements. First, we study how the partners contribution affect the creation and the profit sharing of a JV when partners' effort is not observable.
