Research on the Bending Mechanical Properties of Laminated Glass Panels Under Concentrated Loads

Engineering Reports, Volume 7, Issue 4, April 2025.
This article conducts bending tests on glass bridge decks under wheel loads to study the mechanical properties of glass panel structures applied to automotive bridge decks. The experiment applies a concentrated load to the center of the plate, with displacement as the control condition for loading.

An Improved Communication‐Free Dual Characteristic Over Current‐Based Protection Scheme for AC Microgrids

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
The entry of distributed generation causes the network to become complicated, and as a result, the protection coordination between the network equipment is lost. In previous studies, three decision variables were considered for each directional overcurrent relay: time dial setting in the main mode, time dial setting in the backup mode, and pickup ...

Artificial intelligence based optimal coordination of directional overcurrent relay in distribution systems considering vehicle to grid technology

Ain Shams Engineering Journal
Optimal coordination of overcurrent relays has become a major challenge in power distribution systems due to the increasing participation of distributed generation (DG) and electric vehicle (EV) charging stations, especially vehicle-to-grid (V2G ...

Individual peak alpha frequency correlates with visual temporal resolution, but only under specific task conditions

European Journal of Neuroscience, Volume 60, Issue 7, Page 5591-5604, October 2024.
In the current study, we have replicated the finding from Samaha and Postle's (2015) study that individual peak alpha frequency is correlated with perceptual thresholds for a single‐flash fusion paradigm. However, this correlation is not present for a different measure for visual temporal resolution.

Deformation, Strength and Tectonic Evolution of Basal Ice in Taylor Glacier, Antarctica

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 4, April 2024.
Abstract Observation and measurements of ice structure and deformation made in tunnels excavated into the margin of Taylor Glacier, a polythermal glacier in the McMurdo Dry Valleys of Antarctica, reveal a complex, rapidly deforming basal ice sequence.

Optimizing DOCRs coordination when synergizing energy management with V2G using innovative optimization algorithms

Results in Engineering
This manuscript proposes an optimal coordination approach for directional overcurrent relays (DOCRs) within electric vehicle charging stations (EVCS), considering energy management and Vehicle-to-Grid (V2G) integration.

Optimal overcurrent relay coordination: Balancing costs, time performance and generator placement in fault current limiter optimization

IET Generation, Transmission &Distribution, Volume 18, Issue 7, Page 1431-1448, April 2024.
This work investigates FCL cost minimization through the placement of the synchronous generator location within the network. This will be achieved by implementing JSO algorithm. Restoring the coordination through the FCLs without changing the directional over current relays settings is one goal of this work.

Optimisasi Koordinasi Directional Over Current Relay (DOCR) pada Sistem Distribusi Mesh Menggunakan Modified Adaptive Particle Swarm Optimization (MAPSO) dengan Pembangkit Tersebar

Jurnal Teknik ITS, 2017
Pemilihan topologi jaringan distribusi mesh merupakan salah satu hal yang sangat penting dalam penyaluran sistem tenaga listrik. Apabila terjadi gangguan pada suatu saluran maka saluran yang lain dapat menggantikan untuk penyalurkan daya listrik.
