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.

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.

Nonsuperconducting Fault Current Limiter With Controlling the Magnitudes of Fault Currents

IEEE Transactions on Power Electronics, 2009
In this paper, a diode-bridge-type nonsuperconductor fault current limiter (NSFCL) is proposed. The structure has the capability of controlling the DC reactor current that yields to control the magnitude of fault current. In order to control the magnitude of DC reactor current, a discharging resistor is used in the proposed structure.

Multicell Fault Current Limiter

IEEE Transactions on Industrial Electronics, 2014
A multicell fault current limiter (MCFCL) is proposed in this paper. The MCFCL is composed of multiple fault current limiting cells. Each fault current limiting cell consists of a fault current limiting inductor and a power electronic module. The proposed MCFCL has the flexibility in expanding the operation voltage by increasing the number of fault ...

IGBT Fault Current Limiting Circuit

IEEE Industry Applications Magazine, 1995
Circuits are proposed which, by limiting the fault current magnitude, extends the short-circuit withstand time of high-efficiency (high-gain) IGBTs (insulated-gate bipolar transistors). Limiting of the fault current magnitude also results in reduced turn-off voltage transients, a desirable byproduct, especially for higher current modules. Moreover, the

Comparison between resistive and inductive superconducting fault current limiters for fault current limiting

2012 Seventh International Conference on Computer Engineering & Systems (ICCES), 2012
Superconducting fault current limiters (SFCLs) are used to limit the short-circuit current level in electrical transmission and distribution networks. Applications of SFCLs would not only decrease the stress on network devices, but also can offer a connection to improve the reliability of power system.
