Harmonic distortion factor of space vector PWM for a five-phase inverter
Various PWM methods for multi-phase (n>3) two-level voltage source inverters (VSIs) have been developed recently. Relatively little work has however been done in relation to switching harmonic properties of these PWM methods and their impact on current ...

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

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.

Phase Distortion and Error Vector Magnitude for 8-PSK Systems
, 2008 : The demand for higher data rates in mobile communications is leading to the use of higher order modulation schemes, such as 8-PSK. In such systems distortion is a consequence of magnitude and phase disturbances.

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...
