Hybrid Simulation of Seismic Responses of a Typical Station with a Reinforced Concrete Column

Applied Sciences, 2020
During the 1995 Kobe earthquake, damages were observed in the Daikai subway station and adjacent tunnels. It was the first large-scale underground structure that failed under the earthquake excitation.

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.

Hybrid simulation of steel frames with semi-rigid connections [PDF]

, 2009
Fully-welded connections for earthquake resistance of steel frames are costly and their performance is adversely affected by weld defects and low-cycle fatigue. An alternative to welded connections is the bolted top and seat angle connection.

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Quantifying urban seismic rescue difficulty: a policy-oriented assessment methodology based on building collapse patterns

Geomatics, Natural Hazards & Risk
Post-earthquake rescue efficiency is crucial for urban seismic resilience. However, building collapse patterns, which critically determine rescue difficulty, remain inadequately addressed in urban disaster policies.

Simulation Analysis of Carrier-Based Aircraft Sortie Generation Rate Under Multi-Source Coupled Faults

Journal of Marine Science and Engineering
The sortie generation rate (SGR), a key metric of carrier-based aircraft operations, is severely degraded by multi-source coupled faults across the human–equipment–environment triad. Existing models oversimplify these dynamics by employing static failure

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
