Analysis of a back flashover across insulator strings on a 115 kV transmission line tower by PSCAD
KKU Engineering Journal, 2015 Lightning striking on a transmission tower induces high ground potential rise and high voltage at tower arms in which potential is normally at ground level, and subsequently causes overvoltage across an insulator string.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, EarlyView.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Science Education, EarlyView.ABSTRACT Educating youth about environmental and climate justice is crucial in realizing a sustainable and flourishing future. Yet this can be challenging given the intense eco‐emotions youth experience and express while learning about these consequential realities and their implications.

Small Methods, EarlyView.Cellulose paper is transformed into a high‐performance plasmonic sensor through a process called SILVERED, which involves single‐step vapor deposition onto fluorosilanized fibers. Surface‐energy contrast drives uniform silver nanoparticle growth with sub‐10 nm hot‐spot gaps, achieving 2 pM detection of rhodamine B.

Investigation of lightning ignition characteristics based on an impulse current generator
Ecology and Evolution, 2019 Lightning strike is an important ignition source of forest fires. Artificial lightning discharge is a method for studying lightning fires. However, there is not enough data on the ignition of combustible materials caused by artificial lightning discharge.

Central Bank Digital Currencies, Financial Inclusion, and Privacy: A Normative Perspective
Southern Economic Journal, EarlyView.ABSTRACT Central bank digital currencies (CBDCs) are a digital form of a nation's money, issued by its central bank. As opposed to other forms of digital money, such as electronic bank balances or cryptocurrencies, they are centrally managed legal tender.

The Lightning Current Measurement Based on Wavelet Transform
Modern Applied Science, 2010 Summary: The current model of the lightning process is established and simulated in this article, and aiming at the disadvantage that the hardware filtering de-noising method adopted in the general lightning measurement system can not effectively separate signals and noises in same one frequency channel, this article uses the wavelet transform to ...

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle
steel research international, EarlyView.Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.
