Strike: Stream Cipher Based on Stochastic Lightning Strike Behaviour
Applied Sciences, 2023 There is an increasing need for secure and fast encryption algorithms to support applications and communication protocols, and business models. In this paper, we present an alternative stream cipher (Strike) inspired by the stochastic behaviour of ...

Research on lightning transient distribution characteristics of cable-stayed bridges
暴雨灾害, 2023 Bridges are usually located at the junction of land and water, where the surrounding area is open terrain, making them to be easily damaged by lightning strikes.

Tracking canopy gaps in mangroves remotely using deep learning
Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 890-903, December 2022., 2022 Canopy gaps greatly contribute to mangrove forest turnover and rejuvenation. While gap monitoring is usually performed by field and aerial surveys, we propose a novel method based on deep learning to achieve this automatically from very‐high‐resolution satellite imagery.

Theory of ball lightning [PDF]
Sci. Rep. 6, 28263 (2016), 2014 We present a comprehensive theory on the formation of ball lightning, a luminous sphere sometimes observed after normal lightning. In a ball lightning event, a relativistic electron bunch can be produced by the stepped leader of lightning and coherently emit high-power microwave when striking the ground.

Wind Energy, Volume 26, Issue 2, Page 131-144, February 2023., 2023 Abstract As the height of wind turbine increases, the lightning strike accident has become a non‐negligible issue. In this paper, the lightning attachment characteristic of a 2‐MW wind turbine generator (WTG) is investigated using a model with a reduced scale of 100.

Straight Lightning as a Signature of Macroscopic Dark Matter [PDF]
Phys. Rev. D 103, 063024 (2021), 2020 Macroscopic dark matter (macros) is a broad class of alternative candidates to particle dark matter. These candidates would transfer energy to matter primarily through elastic scattering. A sufficiently large macro passing through the atmosphere would produce a straight channel of ionized plasma.

WIREs Energy and Environment, Volume 12, Issue 1, January/February 2023., 2023 Application of small‐signal analysis tools for power‐electronic‐dominated systems. Abstract The stability, operation, and control of power networks have been challenged due to the increased penetration of power electronic converters. New instability phenomena have appeared due to the interaction of the power converter controllers with other power ...
