A class of nonlinear disturbed coupled Schrdinger systems is studied.The specific technique is used to relate the exact and approximate solutions.The correspo
Exact solutions for generally supported functionally graded plane beams are given within the framework of symplectic elasticity. The Young’s modulus is assumed
The pseudoplastic circular Couette flow (CCF) in annuli is investigated. The viscosity is dependent on the shear rate that directly affects the conservation equ
