Wave loads on ocean infrastructure increase as a result of waves passing over abrupt depth transitions

Li, Zhenhao (author), Tang, Tianning (author), Li, Yan (author), Draycott, Samuel (author), van den Bremer, T.S. (author), Adcock, Thomas A.A. (author)

Abrupt changes in water depth are known to lead to abnormal free-surface wave statistics. The present study considers whether this translates into abnormal loads on offshore infrastructure. A fully non-linear numerical model is used which is carefully validated against experiments. The wave kinematics from the numerical model are used as...

Security Evaluation of the Cyber Networks under Advanced Persistent Threats

Yang, L. (author), Li, Pengdeng (author), Yang, Xiaofan (author), Tang, Yuan Yan (author)

Advanced persistent threats (APTs) pose a grave threat to cyberspace, because they deactivate all the conventional cyber defense mechanisms. This paper addresses the issue of evaluating the security of the cyber networks under APTs. For this purpose, a dynamic model capturing the APT-based cyber-attack-defense processes is proposed....

Identification and Suppression of Multicomponent Noise in Audio Magnetotelluric Data Based on Convolutional Block Attention Module

Zhang, Liang (author), Li, Guang (author), Chen, Huang (author), Tang, Jingtian (author), Yang, Guanci (author), Yu, Mingbiao (author), Hu, Yong (author), Xu, Jun (author), Sun, J. (author)

Audio magnetotelluric (AMT) is commonly used in mineral resource exploration. However, the weak energy of AMT signals makes them susceptible to being overwhelmed by noise, leading to erroneous geophysical interpretations. In recent years, deep learning has been applied to AMT denoising and has shown better denoising performance compared to...

Double-sided numerical thermal modeling of fan-out panel-level MOSFET power modules

Li, Wenyu (author), Chen, Wei (author), Jiang, Jing (author), Tang, H. (author), Fan, J. (author)

Double-sided packages for heat dissipation are an efficient thermal management mechanism for power semiconductor devices. A fan-out panel-level packaging (FOPLP), as one of the double-sided forms, exhibits excellent electro–thermal characteristics and provides low stray inductance and thermal resistance. Besides, the temperature at each point...

An increased number of rogue waves, relative to standard distributions, can be induced by unidirectional waves passing over abrupt decreases in water depth. We investigate this phenomenon in a more general setting of multidirectional waves. We examine the influence of the directionality on the occurrence probability of rogue waves using...
