Transmission Line Galloping Prediction Based on GA-BP-SVM Combined Method
IEEE Access, 2021 The paper proposes a method to construct a model for transmission line galloping prediction using machine learning algorithms to address the transmission line galloping problem, which can result in transmission line loss and pose a greater risk to the ...

The galloping of a 4:1 rectangular cylinder at Re = 300
AIP Advances, 2023 The flow-induced vibration (FIV) of a rectangular cylinder with a side ratio of 4 at Re = 300 is numerically investigated by a two-dimensional spectral-element method. The cylinder is constrained to vibrate only in the cross-flow direction.

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities
Journal of Interior Design, EarlyView., 2022 ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.
