Placement optimization of Multi-Type fault current limiters based on genetic algorithm

Global Energy Interconnection, 2021
The fault current limiter (FCL) is an effective measure for improving system stability and suppressing short-circuit fault current. Because of space and economic costs, the optimum placement of FCLs is vital in industrial applications. In this study, two

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning

Journal of Field Robotics, Volume 43, Issue 6, Page 3617-3632, September 2026.
ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.

Control Design for a Power Electronic Based Fault Current Limiter (FCL)

RE&PQJ
This paper shows a solution for controlling shortcircuit currents of a power electronic based Fault Current Limiter (FCL). A model for control design of three-phase short-circuit currents will be presented. A way of limiting the maximum aperiodic short-circuit current is derived with special regards to the stability of the entire system.

Discriminant validity and interrelations of conceptual and procedural knowledge in fractions and algebra: Evidence from confirmatory factor analysis

British Journal of Educational Psychology, Volume 96, Issue 3, Page 1396-1418, September 2026.
Abstract Background Conceptual and procedural knowledge are two distinct types of mathematical knowledge. Measuring them with sufficient discriminant validity is challenging because they are typically highly correlated. Prior studies have demonstrated discriminant validity of paper‐and‐pencil measures separately for fractions and algebra.

Multidisciplinary Exploration of Computed‐Tomographic and Ancient‐DNA Data of an Iron Age Skull From Latvia With Multiple Lytic Bone Lesions: Differential Diagnosis Between Metastatic Carcinoma, Multiple Myeloma and Skeletal Tuberculosis

Ecology and Evolution, Volume 16, Issue 7, July 2026.
In this study we used a combined computed tomographic and archaeogenetic approach to analyse a skull and vertebra with lytic lesions from a disturbed grave in the Čunkāni‐Dreņģeri cemetery in Latvia, dated to 10th century CE. Both methodologies were used to evaluate a proposed differential diagnosis of multiple myeloma, metastatic carcinoma and bone ...

A novel current-limiting hybrid DC breaker based on thyristors

Energy Reports, 2023
Since the DC current has no zero-crossing in high-voltage and large-capacity DC scenarios, and the low line impedance results in a large growth rate of fault current, the breaking requirements of DC circuit breakers (DCCB) are further increased.

Contralateral Thermal Pain and Naturally Occurring Muscle Pain Have Different Effects on Force Production During a Fixed Perceived Effort Handgrip Task

European Journal of Pain, Volume 30, Issue 6, July 2026.
ABSTRACT Background In the presence of pain, performance during imposed workload motor tasks may be maintained at the cost of a higher perceived effort. This study investigated how experimentally induced contralateral thermal pain and naturally occurring muscle pain influence force production during a fixed perceived effort task.

New Computational Method for Optimal Allocation of Fault Current Limiters in Power Systems

Iranian Journal of Electrical and Electronic Engineering, 2021
Expansion of power system causes short-circuit currents (SCC) of networks to exceed the tolerable SCCs of equipment. The utilization of fault current limiter (FCL) in such networks is needed to address this issue.
