Reconstruction of Wing Structure Deformation Based on Particle Swarm Optimization Ridge Regression

open access: yesInternational Journal of Aerospace Engineering, 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

Reconstruction of the Breast Conservation Deformity [PDF]

open access: yesSeminars in Plastic Surgery, 2004
The era of breast conserving treatment of early-stage breast carcinoma has created reconstructive challenges for the plastic surgeon. Although good to excellent cosmetic outcomes occur in the majority of patients, a significant number could benefit from additional reconstructive measures. Because of the need for continuing surveillance following breast-
