Power hardware in the loop validation of fault ride through of VSC HVDC connected offshore wind power plants

open access: yesJournal of Modern Power Systems and Clean Energy, 2014
This paper presents the power hardware in the loop (PHIL) validation of a feed forward DC voltage control scheme for the fault ride through (FRT) of voltage source converter (VSC) high voltage DC (HVDC) connected offshore wind power plants (WPPs). In the

Convolution, Correlation and Generalized Shift Operations Based on the Fresnel Transform

open access: yesSensors, 2023
The Fresnel transform (FrT) is commonly used to describe the free-space propagation of optical waves. In this work, we present new definitions for the convolution, correlation and generalized shift operations based on the FrT.

The economic foundations of powersharing: Evidence from Africa

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract How—and with whom—do rulers share power? Existing research focuses on the strategic logic of powersharing. In this paper, we analyze its economic foundations. Powersharing is modeled as a subnational fiscal contract, in which rulers allocate political representation based on constituencies’ revenue potential. Empirically, we combine historical

Fast analytical calculation-based modeling method and fault ride-through parameters selection to enhance short-term voltage stability of grids with large-scale photovoltaic power plants

open access: yesInternational Journal of Electrical Power & Energy Systems
Large-scale centralized photovoltaic power plants (PVPPs) connected to a power grid may cause short-term voltage instabilities during fault ride-through (FRT) processes.

Activation of peripheral NOP receptors reduces periorbital mechanical allodynia evoked by CGRP in mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Migraine is a neurovascular disorder largely mediated by calcitonin gene‐related peptide (CGRP). This study explores the role of the nociceptin/orphanin FQ (N/OFQ)–N/OFQ receptor (NOP) system in CGRP‐induced periorbital mechanical allodynia (PMA) in mice.

On the Dynamics of Human Proximity for Data Diffusion in Ad-Hoc Networks

open access: yes, 2011
We report on a data-driven investigation aimed at understanding the dynamics of message spreading in a real-world dynamical network of human proximity. We use data collected by means of a proximity-sensing network of wearable sensors that we deployed at ...

FRT Regulation in China

open access: yesSSRN Electronic Journal
This paper first introduces China's legal framework regulating facial recognition technology (FRT) and analyzes the underlying problems. Although current laws and regulations have restricted the development of FRT under some circumstances, these restrictions may function poorly when the technology is installed by the government or when it is deployed ...

New biosensors and transgenic mice for multiplex cGMP imaging

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP
