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.

Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]

, 2015
Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

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 ...

A non-linear energy-based framework for fatigue life prediction in semi-crystalline thermoplastics: application to PEEK

Materials Research Express
Semi-crystalline thermoplastics such as polyether ether ketone (PEEK) present a fundamental challenge to conventional fatigue assessment: cumulative plastic energy dissipation increases with fatigue life, contrary to the inverse trend established for ...

Reduced-Precision and Reduced-Exponent Formats for Accelerating Adaptive Precision Sparse Matrix–Vector Product

Mixed precision algorithms aim at taking advantage of the performance of low precisions while maintaining the accuracy of high precision. In particular adaptive precision algorithms dynamically adapt at runtime the precisions used for different variables or operations. For example Graillat et al (2023) have proposed an adaptive precision sparse matrix--

The Influence of Space Charges on the Life Exponent derived from Accelerated Life Tests on PP-based HVDC Cable Insulation. Part 1: Ternary Blends

IEEE Transactions on Dielectrics and Electrical Insulation
The goal of this investigation is to validate the Inverse Power Model (IPM)-Arrhenius electro-thermal life model via the results of Accelerated Life Tests carried out at various voltages and temperatures on polypropylene-based blends developed in the NEWGEN project, to assess the endurance of this new insulation for HVDC cables to electro-thermal ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

The Influence of Space Charges on the Life Exponent from Accelerated Life Tests on PP-based HVDC Cable Insulation. Part 2: Binary Blends and Final Comparison with Ternary Blends

IEEE Transactions on Dielectrics and Electrical Insulation
The goal of this investigation is to validate the IPM-Arrhenius electro-thermal life model by means of the results of Accelerated Life Tests performed at different voltages and temperatures on polypropylene blends put forward in the NEWGEN project. Part 1 of this study focused on theoretical arguments and on this validation of such IPM on a ternary ...
