Research on Transformer Winding Deformation and Winding Resistance
DEStech Transactions on Environment, Energy and Earth Science, 2016 In this paper, the influence of transformer winding deformation on the equivalent electrical parameters is studied, and the proximity effect and skin effect caused by AC current in the wire are simulated. It is verified that the current distribution will be affected by the proximity effect and skin effect.

Wind-induced deformations in a segmented mirror [PDF]
Applied Optics, 2002 A Zernike expansion of wind-induced deformations in a segmented mirror is described. The wind model is a frozen turbulent field with a Kolmogorov spectrum for scales smaller than the outer scale and a flat spectrum for scales larger than the outer scale.

Simulation and Control of Deformable Autonomous Airships in Turbulent Wind
, 2022 AbstractFixed wing and multirotor UAVs are common in the field of robotics. Solutions for simulation and control of these vehicles are ubiquitous. This is not the case for airships, a simulation of which needs to address unique properties, i) dynamic deformation in response to aerodynamic and control forces, ii) high susceptibility to wind and ...
