Reconstruction of Wing Structure Deformation Based on Particle Swarm Optimization Ridge Regression
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 In this paper, a typical airfoil aluminum plate structure is taken as the research object. A structural deformation monitoring and reconstruction method, PSO‐RR (particle swarm optimization‐ridge regression) algorithm, is proposed. A variety of different complex load cases are applied to the airfoil structure, and the strain values at some specific ...

Comparison of the mechanical properties of milk fouling and whey protein fouling
Proceedings in Applied Mathematics and Mechanics, Volume 19, Issue 1, November 2019., 2019 Abstract The formation of fouling deposit is a significant problem for the dairy industry. Many experimental analyses have been carried out to explore the cleaning process using whey protein solution as a surrogate material because the main fouling components in milk are whey proteins.
