Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

A new finite-time average consensus protocol with boundedness of convergence time for multi-robot systems

International Journal of Advanced Robotic Systems, 2017
Multi-robot consensus has been extensively applied in robotics. In this study, a new protocol is proposed to solve the finite-time average consensus problem. The protocol can improve the convergence rate.

Asynchronous finite-time H∞ control for Markov jump systems with T-S fuzzy rules(T-S模糊Markov跳变系统的有限时间H∞异步控制)

Zhejiang Daxue xuebao. Lixue ban
This paper addresses the problem of fuzzy-state-feedback-controller-based finite-time H∞ asynchronous control for a class of Markov jump systems under Takagi-Sugeno fuzzy rules. The hidden Markov model is employed to describe the asynchronization between
