Energy Flows Balance of Electric‐Heating Interconnected Microgrids Under Grid‐Forming Converter Integration Based on Heterogeneous Graph Convolutional Network

open access: yesEnergy Internet, EarlyView.
ABSTRACT The combination of electric‐heating interconnected microgrids (EHIMs) with grid‐forming converters (GFMCs) offers a highly promising approach to improving energy management within decentralised energy systems. Despite its potential, precisely modelling and analysing energy flow in such systems remains a considerable challenge due to the ...

New Quasi-Newton (Dfp) With Logistic Mapping

open access: yesScience Journal of University of Zakho, 2016
In this paper, we propose a modification of the self-scaling quasi-Newton (DFP) method for unconstrained optimization using logistic mapping. We shoe that it produces a positive definite matrix.

Modifications for Quasi-Newton Method and Its Spectral Algorithm for Solving Unconstrained Optimization Problems

open access: yesمجلة بغداد للعلوم
In this paper, two modifications for spectral quasi-Newton algorithm of type BFGS are imposed. In the first algorithm, named SQNEI, a certain spectral parameter is used in such a step for BFGS algorithm differs from other presented algorithms.

A systematic review and meta‐analysis of school‐based interventions for PTSD and trauma‐related symptoms: what effective elements they have in common?

open access: yesChild and Adolescent Mental Health, EarlyView.
Background Schools provide critical support for students exposed to traumatic experiences, with school‐based trauma interventions demonstrating reductions in posttraumatic stress symptoms. However, heterogeneity in design, implementation, and efficacy of existing interventions makes it challenging to select suitable interventions and to understand ...

Fast Injective Mesh Parameterization via Beltrami Coefficient Prolongation

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a highly efficient and robust method for free boundary injective parameterization of disk‐like triangle meshes with low isometric distortion. Harmonic function–based approaches, grounded in a strong mathematical framework, are widely employed.

Combined Quasi-Newton Methods with Two-Dimensional Search for Degenerate Unconstrained Optimization in Machine Learning

open access: yesJournal of Optimization, Differential Equations and Their Applications
This paper presents a two-dimensional search algorithm for quasi-Newton methods applied to ill-conditioned and degenerate unconstrained optimization problems. At each iteration, the space is decomposed into an orthogonal sum of two subspaces based on the
