Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors

Energy Science &Engineering, EarlyView.
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.

First‐Principles Study of Novel A2CaTiH6 (A = Li, Na, K, Rb) Hydrides for Solid‐State Hydrogen Storage Applications

Energy Science &Engineering, EarlyView.
First‐principles investigation of A2CaTiH6 (A = Li, Na, K, Rb) hydrides reveals structural, electronic, mechanical, thermodynamic, and hydrogen storage properties. Negative formation energies confirm stability, while all compounds are metallic and mechanically stable. K2CaTiH6 and Rb2CaTiH6 are dynamically stable, with capacities of 2.28 wt.%–5.61 wt.%.

Triggered Calcium Lightning Programs Cochlear Development

Exploration, EarlyView.
Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

A Review of Automatic Measurement of Learning Engagement Using Body Clues

Future in Educational Research, EarlyView.
ABSTRACT Learning engagement is an overarching multifaceted construct that includes behavioral, cognitive, and emotional dimensions. The static subjective measurements may lead to inaccurate results. Considering the authenticity and reliability of body signals, this study investigated the types of body cues used in measuring learning engagement and ...

On the Variability of Results for Cylinder Flow: A Systematic Analysis of Parameter Sensitivity Within the Lattice Boltzmann Method

International Journal for Numerical Methods in Fluids, EarlyView.
This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.
