Space Vector PWM Technique for a Three-level Asymmetrical Six-phase Drive [PDF]

open access: yes
A space vector pulse-width modulation (SVPWM) strategy for a three-level asymmetrical six-phase drive, with a single neutral point, based on vector space decomposition (VSD) approach is presented for the first time in this paper.

Compositional uniformity, domain patterning and the mechanism underlying nano-chessboard arrays

open access: yes, 2012
We propose that systems exhibiting compositional patterning at the nanoscale, so far assumed to be due to some kind of ordered phase segregation, can be understood instead in terms of coherent, single phase ordering of minority motifs, caused by some ...

Digital space vector modulation decoupled control scheme grid connected 1-Ø riven bias inverter to suppress high-frequency current commutation

open access: yesThe International Journal of Electrical Engineering & Education, 2018
A single-juncture topology of 3-Ø boost inverter with riven DC supply configuration grieves from larger incidence current commutations across the diodepassive in connection with the DC source and the intricate study as the inductor charges with ...

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Isotropic magnetometry with simultaneous excitation of orientation and alignment CPT resonances

open access: yes, 2010
Atomic magnetometers have very high absolute precision and sensitivity to magnetic fields but suffer from a fundamental problem: the vectorial or tensorial interaction of light with atoms leads to "dead zones", certain orientations of magnetic field ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

A MODIFIED VIRTUAL SPACE VECTOR MODULATION TECHNIQUE FOR Z-SOURCE NPC INVERTERS [PDF]

open access: yesCarpathian Journal of Electrical Engineering, 2018
A modified virtual space vector modulation approach for the control of a Z-source neutral point clamped inverter is presented in this paper. This approach works perfectly for the traditional neutral point clamped inverter.

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.
