An Approach to Improve System Performance in the Vehicle-Grid System Using Sliding Mode Control Under Multiple Operation Conditions

open access: yesIEEE Access, 2020
To improve the performance of vehicle-grid system under multiple operation conditions and suppress the low-frequency oscillation (LFO) in electrified railways, this paper proposed a control strategy of electric multiple units (EMUs) traction line-side ...

THE EMU STRIKES BACK: AN INQUIRY INTO AUSTRALIA’S PECULIAR MILITARY ACTION OF 1932 [PDF]

open access: yesRomanian Journal of Historical Studies, 2019
Military failures such as the infamous Great Emu War of 1932 Western Australia are arguably difficult to match in military history. In this article, we tackle the Seventh Heavy Battery of the Royal Australian Artillery’s attempt to ‘wage war’ on the ...

Fiscal Stabilisation and EMU [PDF]

open access: yesCESifo Economic Studies, 2004
This paper builds on the papers published by HM Treasury in 2003 alongside the UK Government's assessment of the case for EMU entry. The paper considers the potential for fiscal policy to play a greater role in stabilisation policy if the UK were inside EMU.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...
