Metal Valence State Modulation Strategy to Design Core@shell Hollow Carbon Microspheres@MoSe2/MoOx Multicomponent Composites for Anti-Corrosion and Microwave Absorption.

Small
The exploitation of multicomponent composites (MCCs) has become the main pathway for obtaining advanced microwave absorption materials (MAMs). Herein, a metal valence state modulation strategy is proposed to tune the electromagnetic (EM) parameters and ...

An Optimized Modulation Strategy for the Three-Level DAB Converter With Five Control Degrees of Freedom

IEEE transactions on industrial electronics (1982. Print), 2020
Compared with the conventional two-level dual-active-bridge (DAB) dc–dc converter, the three-level DAB converter could operate with lower voltage rated switching devices and provide more control degrees of freedom, which enhances the control flexibility.

Modulating speed-accuracy strategies in major depression

Journal of Psychiatric Research, 2015
Depression is associated with deficits in cognitive flexibility. The role of general slowing in modulating more specific cognitive deficits is however unclear.We assessed how depression affects the capacity to strategically adapt behavior between harsh and prudent response modalities and how general and specific processes may contribute to performance ...

Single-Degree-of-Freedom Hybrid Modulation Strategy and Light-Load Efficiency Optimization for Dual-Active-Bridge Converter

IEEE Journal of Emerging and Selected Topics in Power Electronics
Dual-active-bridge (DAB) converters either adopt single-degree-of-freedom (SDOF) modulation or multiple-degree-of-freedom modulation. The SDOF single-phase-shift (SPS) modulation has low power transmission efficiency under light load, and the multiple ...

Predictive modulation strategy for multiswitching converters

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
The present paper proposes an improved predictive modulation strategy for multiconverter systems. Its features are fixed switching frequency and precalculated commutation instants, allowing an accurate phase shift of the current ripple. Flux linkages are assumed as control variables to allow insensitivity to possible inductance nonlinearity and ...

Reconstruction Strategies for Modulated Polarimeters

Imaging and Applied Optics, 2011
Modulated polarimeters measure the polarimetric information in an optical field by modulating the intensity in a polarization-dependent way. This modulation creates side bands in Fourier transform space that carry the desired information.
