Numerically Efficient Average-Value Model for Voltage-Source Converters in Nodal-Based Programs

IEEE Open Journal of Power Electronics
Discrete detailed models of high-frequency switching voltage source converters (VSCs) are accurate but computationally expensive in simulations of large power-electronics-based systems.

Dense active matter model of motion patterns in confluent cell monolayers [PDF]

, 2020
Epithelial cell monolayers show remarkable displacement and velocity correlations over distances of ten or more cell sizes that are reminiscent of supercooled liquids and active nematics.

Measurement-Assisted Quantum Communication in Spin Channels with Dephasing [PDF]

, 2015
We propose a protocol for countering the effects of dephasing in quantum state transfer over a noisy spin channel weakly coupled to the sender and receiver qubits.

Circulating Current Reduction in MMC-HVDC System Using Average Model

Applied Sciences, 2019
Modular multilevel converters (MMCs) are quickly emerging as a suitable technology for a voltage-source converter-based high-voltage direct-current (VSC-HVDC) transmission systems due to its numerous advantages as reported in literature.

Numerically Enhanced Interfacings for Average-Value Models of Voltage-Source Converters in Nodal-Based EMT Simulators

Energies
Efficient simulations of converter-dominated power systems and microgrids significantly rely on average-value models (AVMs) of the converters. The conventional AVMs of voltage-source converters (VSCs) typically require a time-step delay for interfacing ...

A framework for the evaluation of turbulence closures used in mesoscale ocean large-eddy simulations

, 2012
We present a methodology to determine the best turbulence closure for an eddy-permitting ocean model through measurement of the error-landscape of the closure's subgrid spectral transfers and flux.

Changes in Hemodynamic Responses in Chronic Stroke Survivors Do Not Affect fMRI Signal Detection in a Block Experimental Design [PDF]

, 2013
The use of canonical functions to model BOLD-fMRI data in people post-stroke may lead to inaccurate descriptions of task-related brain activity. The purpose of this study was to determine whether the spatiotemporal profile of hemodynamic responses (HDRs)

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Facilitating wide-band oscillation analysis in wind farms with a novel linearization analysis framework based on the average-value model

iEnergy
Wide-band oscillations have become a significant issue limiting the development of wind power. Both large-signal and small-signal analyses require extensive model derivation.

Structural Properties of the Caenorhabditis elegans Neuronal Network [PDF]

, 2010
Despite recent interest in reconstructing neuronal networks, complete wiring diagrams on the level of individual synapses remain scarce and the insights into function they can provide remain unclear.
