Spin and pseudospin symmetries in radial Dirac equation and exceptional hermite polynomials

Reliability Analysis of Concrete Gravity Dams Based on Least Squares Support Vector Machines with an Improved Particle Swarm Optimization Algorithm

“…Lu et al [8] proposed a second fourth-order moment calculation method for reliability calculations based on the first fourth-order moment of the second-order approximation of the functional function and proved its simplicity and accuracy. Jiang et al [9] proposed a reliability analysis method for gravity dams based on the Hermite orthogonal polynomial approximation method and illustrated the correctness and effectiveness of the proposed method by arithmetic examples. Ren et al [10] proposed a sensitivity-assisted MC simulation method in which second-order derivatives were introduced to improve the accuracy of reliability calculations.…”
