... analytical models. Design/methodology/approach The study uses asymptotic analysis to derive analytical solutions for blood velocity and pressure in a microvessel with a small radius. This approach simplifies the NP and heat transport equations into two ordinary differential equations, which...

... directions in the shallow water of uniform depth. Design/methodology/approach Pfaffian technique is used to construct the Gramian solutions of the (2 + 1)-dimensional BKK system. Asymptotic analysis is applied on the two-soliton solutions to study the interaction properties. Findings N...
