Short‐Term Multi‐Horizon Line Loss Rate Forecasting of a Distribution Network Using Attention‐GCN‐LSTM

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurately predicting line loss rates is crucial for effective management in distribution networks, particularly for short‐term multihorizon forecasts ranging from 1 hour to 1 week. In this study, we propose attention‐GCN–LSTM, a novel method that integrates graph convolutional networks (GCN), long short‐term memory (LSTM) and a three‐level ...

Double‐Integration‐Enhanced Stochastic Gradient Descent Based on Neural Dynamics for Improving Generalisation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Generalisation is a crucial aspect of deep learning, enabling models to perform well on unseen data. Currently, most optimisers that improve generalisation typically suffer from efficiency bottlenecks. This paper proposes a double‐integration‐enhanced stochastic gradient descent (DIESGD) optimiser, which treats the negative gradient as an ...

Insulation–Vibration Dynamics Model and Experimental Investigation of Cable Gas‐Insulated Switchgear Terminations

High Voltage, EarlyView.
ABSTRACT Numerous breakdowns in cable gas‐insulated switchgear (GIS) terminations stem from inadequate insulation and interfacial stresses. However, existing diagnostic techniques, such as partial discharge detection and microwave detection, are highly susceptible to electromagnetic interference, or their diagnostic signals are often attenuated by the ...

Exchange‐Rate Responses to Structural Oil‐Market Shocks: Revisiting Krugman's Real–Financial Adjustment Framework

Australian Economic Papers, EarlyView.
ABSTRACT This study examines how structural oil‐market shocks affect exchange rates through the real and financial adjustment mechanisms proposed by Krugman (1983). Using a two‐stage SVAR–ARDL/NARDL framework, we identify oil supply, aggregate demand, and oil‐specific demand shocks and estimate their symmetric and asymmetric effects for oil‐importing ...

Effects of Green Finance on Economic Growth and Renewable Energy in Developing Countries: A Panel Cointegration Analysis

Natural Resources Forum, EarlyView.
ABSTRACT This empirical study examines the impact of green finance on economic growth and renewable energy in a group of 76 developing nations in 2010–2019. Results from a cointegration analysis, vector error correction model, and Granger causality test confirm a cointegrating relationship between green finance, renewable energy, economic growth, and ...

Identification of nonlinear systems by use of nonstationary white-noise inputs

Applied Mathematical Modelling, 1980
Abstract The nonparametric identification of methodology which utilizes white-noise test inputs to obtain models for nonlinear dynamic systems is extended to cover the case of nonstationary white-noise inputs. This situation arises in several practical instances of interest, e.g. earthquake signals can be viewed as nonstationary band-limited Gaussian

Market Integration and Nonlinear Price Transmission in 19th‐Century British Wheat Markets

Journal of Agricultural Economics, EarlyView.
ABSTRACT Important developments in infrastructure and institutions characterized 19th‐Century wheat markets in Great Britain. Among these developments was the construction of the national rail system which enabled cheaper and more efficient transport of grain and other bulky cargoes between inland towns and ports.

Coupled Nonlinear Torsional Seismic Behaviour of a Triple-Friction-Pendulum-Isolated Five-Storey RCC Building Under Nonstationary Earthquake Excitation

Buildings
Triple Friction Pendulum (TFP) bearings are widely employed as seismic isolation systems to reduce seismic force and deformation demands in structures. However, the combined influence of vertical mass-distribution irregularity, soil–structure interaction

Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

Fisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...
