Active power sharing and voltage regulation are two of the major control challenges in the operation of the voltage source converter based multi-terminal high-voltage DC (VSC-MTDC) system when integrating large-scale offshore wind farms (OWFs).This paper proposes two novel adaptive voltage reference based droop control methods to regulate pilot DC
Magnetic resonance imaging (MRI) is used to image root systems grown in opaque soil.However, reconstruction of root system architecture (RSA) from 3-dimensional (3D) MRI images is challenging.Low resolution and poor contrast-to-noise ratios (CNRs) hinder automated reconstruction.Hence, manual reconstruction is still widely used.Here, we evaluate a
A complete understanding of the mechanistic basis of marine ecosystem functioning is only possible through integrative and interdisciplinary research.This enables the prediction of change and possibly the mitigation of the consequences of anthropogenic impacts.One major aim of the COST Holiday Stockings Action ES0609 Seagrasses productivity.From ge
DOI:10.17014/ijog.2.3.167-184Strong mineralized carbonate rock-bearing Pb-Zn-Cu-Ag-(Au) ores are well exposed on the Latong River area, Madina Regency, North Sumatra Province.The ore deposit is hosted within the carbonate rocks of the Permian to Carboniferous Tapanuli Group.It is mainly accumulated in hollows replacing limestone in the forms of len
