Magnetic field energy harvesting (MFEH) is a method by which system can harness an ambient, alternating magnetic in order to scavenge energy. Presented this article novel application of the concept aimed at fields surrounding rail current electrified railway. Due its non-invasive nature, approach has potential be widely deployed as part low-cost trackside condition monitoring systems increase l...

Journal: :Railway Engineering Science 2021

Abstract Electrified railways are becoming a popular transport medium and these consume large amount of electrical energy. Environmental concerns demand reduction in energy use peak power railway systems. Furthermore, high transmission losses DC systems make local storage an increasingly attractive option. An optimisation framework based on genetic algorithms is developed to optimise electric r...

Journal: :Space Weather-the International Journal of Research and Applications 2023

Abstract Studies of space weather impacts on ground‐based infrastructure have been largely focused power networks and pipelines, but railway signaling systems are also affected, with misoperations observed in several countries. This paper advances recent theoretical work geomagnetically induced currents by modeling realistic lines parameters from current industrial standards. Focusing two examp...

OBJECTIVE To observe changes on cell membrane in blood cells after they were been electrified. METHODS Blood were electrified for 5, 10, 20, 30 s, 1 min respectively, and Scanning electron microscope was used to detect the changes on their cell membranes. RESULTS Pores were detected both on electrified erythrocytes and leukocytes with round or ellipse shapes. The erythrocytes often have one...
