Uwe Buschcontrol laws and the optimization of dynamical systems. These constructive approaches rely on small parameter methods (averaging, regular and singular perturbations), which are well-known and have been proven to be efficient in nonlinear mechanics and optimal control theory (maximum principle, variaMedicaid 发表于 2025-3-25 10:43:19

Experimental and Simulation Study on the Stress Characteristics of Precast U-Shaped Beam Slab of Prestressed Concrete for High-Speed Railwaysonally, by integrating the results of linear and nonlinear finite element analysis, it summarizes the stress characteristics of precast U-shaped beam slabs made of prestressed concrete. This provides references for the design and construction of precast U-shaped beam slabs of prestressed concrete.小平面 发表于 2025-3-26 20:19:49
