Exploring Cultural and Individual Differences in the Hierarchy of Moral Concern: Evidence From Student Samples Across 41 Cultural Groups

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Many important historical and contemporary ethical debates (e.g., on slavery, abortion and environmental protection) reflect disagreements about what we owe to different groups of individuals. Recent work in moral psychology has uncovered a seemingly replicable hierarchy of moral concern, but these studies were conducted in a few countries ...

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Application of UPFC to improve the low-voltage-ride-through capability of DFIG

open access: yes, 2015
In this paper, a new controller approach for unified power flow controller (UPFC) is proposed to improve the low-voltage-ride-through (LVRT) capability of a DFIG-based WECS during voltage sag.

A Control Strategy With Hybrid Compressor Modeling for Electric Vehicle CO2 Heat Pump Systems

open access: yesEnergy Science &Engineering, EarlyView.
A hybrid PSO‐BP compressor sub‐model is developed and embedded in a MATLAB/Simscape physical model of a transcritical CO2 heat pump system for electric vehicles. Based on this high‐fidelity platform, a phased variable‐PTC cooperative control strategy is proposed and evaluated.

Power angle based fault recovery analysis for grid-connected GFM inverters with current limiting

open access: yesInternational Journal of Electrical Power & Energy Systems
To meet both the requirements of current limiting and ancillary services during fault ride-through (FRT) of the GFM inverters, various current limiting strategies are developed.

The prevalence of Streptococcus equi subsp. equi carriers in the Netherlands

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Streptococcus equi subspecies equi (S. equi) carriers are thought to be important drivers for strangles outbreaks. Limited data are available on the prevalence of carriers in European horse husbandry settings. Objectives To estimate the prevalence of S.

Comparative Performance Evaluation of Wind Energy Systems Using Doubly Fed Induction Generator and Permanent Magnet Synchronous Generator

open access: yesWind
Wind energy has become a cornerstone of sustainable electricity generation, yet the reliable integration of wind energy conversion systems (WECSs) into modern grids remains challenged by dynamic variations in wind speed and stringent fault ride-through ...
