Torque Ripple Reduction in Modular Drive of a Non-Sinusoidal, Asymmetric Six-Phase, Permanent Magnet Synchronous Motor with Double Stator Windings using Harmonic Current Injection Strategy [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization
Multiphase permanent magnet synchronous motors (PMSMs) are widely adopted in high-power-density and high-efficiency applications, particularly where reliability is a critical design requirement.

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

open access: yesAdvanced 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

Winding of geodesic rays chosen by a harmonic measure [PDF]

open access: yes
We prove limit theorems for the homological winding of geodesic rays distributed via a harmonic measure on a Gromov hyperbolic space. We obtain applications to the inverse problem for the harmonic measure, and winding statistics for Patterson-Sullivan ...

Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]

open access: yes, 2012
We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...

Construction and Application of Online Vibration Frequency Response Analysis Method for Converter Transformer Winding

open access: yesHigh Voltage
The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration ...

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

open access: yesAdvanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.
