Direct instantaneous torque control for switched reluctance machines considering mutual coupling

The Journal of Engineering, 2019
Torque ripple reduction is the main goal of direct instantaneous torque control (DITC). However, the quality of the switched reluctance machine control is only as good as its machine model.

Impact of Mutual Coupling on Power-Domain Non-Orthogonal Multiple Access (NOMA)

IEEE Access, 2020
This paper investigates the impact of mutual coupling (MC) on the achievable sum-rate of power-domain non-orthogonal multiple access (NOMA) system in both uplink (UL) and downlink (DL) transmissions.

The new concept of nano-device spectroscopy based on Rabi-Bloch oscillations for THz-frequency range

, 2017
We considered one-dimensional quantum chains of two-level Fermi particles coupled via the tunneling driven both by ac and dc fields in the regimes of strong and ultrastrong coupling.

Energy efficiency of information transmission by electrically coupled neurons

, 2012
The generation of spikes by neurons is energetically a costly process. This paper studies the consumption of energy and the information entropy in the signalling activity of a model neuron both when it is supposed isolated and when it is coupled to ...

Efficient Real-Valued Rank Reduction Algorithm for DOA Estimation of Noncircular Sources Under Mutual Coupling

IEEE Access, 2018
Noncircular sources are widely used in wireless communication array systems, which can offer more accurate estimates and detect more sources. However, in practical array systems, the directionof-arrival (DOA) estimation performance may be severely ...

Phase reduction approach to synchronization of spatiotemporal rhythms in reaction-diffusion systems

, 2014
Reaction-diffusion systems can describe a wide class of rhythmic spatiotemporal patterns observed in chemical and biological systems, such as circulating pulses on a ring, oscillating spots, target waves, and rotating spirals. These rhythmic dynamics can

Mutual Coupling Reduction Between Axial-Mode Helical Antennas using Single-Negative (SNG) Magnetic Metamaterials

The Journal of Engineering Research, 2010
This paper investigates the mutual coupling effects between axial-mode helical antenna arrays. Single-negative (SNG) magnetic metamaterials are developed and used in this work in order to reduce mutual coupling between axial-mode helical antennas used in

Ground-gamma band mixing and evolution of collectivity in even-even neutron-rich nuclei with 40

, 2004
We propose an extended band mixing formalism capable of describing the ground-gamma band interaction in a wide range of collective spectra beyond the regions of well deformed nuclei.
