Frequency‐Domain Subspace Identification for Noninvasive Transformer Winding Parameter Estimation and Fault Diagnostics

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
Noninvasive frequency‐domain method estimates transformer winding parameters from terminal measurements, eliminating the need for design data. ABSTRACT A novel frequency‐domain subspace identification method enables precise estimation of transformer winding ladder network parameters directly from terminal measurements.

Truth‐telling in the Australian Curriculum

open access: yesThe Curriculum Journal, EarlyView.
Abstract Unlike Canada and South Africa, Australia has not completed a national Truth‐telling of First Nations histories. As a consequence, the curriculum is at risk of excluding Truth‐telling, leading to indoctrination of past injustices as part of school learning.

AI‐Driven Optimization Techniques for Power Quality Improvement in Microgrids: Trends, Techniques, and Future Directions

open access: yesEnergy Science &Engineering, EarlyView.
Decentralized energy systems are gaining momentum, and microgrids have become a vital component of the modern power landscape. Yet, maintaining power quality within these systems presents ongoing challenges due to the presence of nonlinear loads, variable renewable energy sources, and frequent switching operations.

Improving the Convergence of Vector Fitting for Equivalent Circuit Extraction From Noisy Frequency Responses [PDF]

open access: yes, 2006
The vector fitting (VF) algorithm has become a common tool in electromagnetic compatibility and signal integrity studies. This algorithm allows the derivation of a rational approximation to the transfer matrix of a given linear structure starting from ...

Extreme wildfire conditions shift coastal phytoplankton community structure in California

open access: yesLimnology and Oceanography, EarlyView.
Abstract Extreme wildfires have increased in frequency and intensity globally, particularly in the Western United States. Here we examine how the 2020 Lightning Complex Fires in California influenced coastal phytoplankton communities using monitoring network data products in the Monterey Bay, the ocean region closest to this large fire.

Understanding fire conflict through stakeholder mapping in Madagascar's grassy biomes

open access: yesPeople and Nature, EarlyView.
Abstract Fire management in biodiverse regions where rural communities depend on traditional fire‐use practices presents a complex global challenge, particularly in Madagascar where fire is considered a threat to forests yet is essential for maintaining grassland ecosystem health and rural livelihoods.

Ground Temperature Monitoring During the Period 2004–2024 Indicates Permafrost Degradation in the Austrian Alps

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Long‐term time series on changes in the cryosphere are becoming increasingly important. This study presents data from 20 years of ground temperature monitoring from the eastern‐most confirmed permafrost site in the European Alps (Hochreichart, Austria) spanning the period 2004–2024.

Evaluation of the WRF model for simulating deep convection and cold‐pool characteristics relevant to wind‐energy applications in Germany

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Deep convection and cold‐pool characteristics over Germany during July 2023 are investigated using Deutscher Wetterdienst (DWD) radar observations and a Weather Research and Forecasting (WRF) model simulation. The temporal evolution of convective cell features reveals a downward‐facing parabolic pattern in both WRF and observations, in terms of cell ...
