Summary: In this paper, the time-fractional coupled viscous Burgers' equation and Drinfeld-Sokolov-Wilson equation are solved using the Sawi transform coupled homotopy perturbation method. The approximate series solutions to these equations are obtained, and the absolute error between the approximate solution and the exact solution is analyzed. The properties of the equations are given as a conclusion by comparing the graphs of the function when the fractional order takes different values.

Summary: In this paper, the Mohand transform-based homotopy perturbation method is proposed for solving two-dimensional linear and non-linear shallow water wave equations. This approach has been proven to be suitable for a wide range of non-linear differential equations in both science and engineering. Graphs are provided to show the variation trend of the water surface elevation at different time levels and depths. Additionally, the obtained solutions are compared with existing results, demonstrating higher efficiency and fewer computations than other approaches studied in the literature.

Summary: This article introduces the Modified Integral Homotopy Expansive Method (MIHEM) for finding power series solutions to linear ordinary differential equations about ordinary points. The method is a modification of the integral homotopy expansive method and provides a versatile, easy to use, and systematic approach. MIHEM requires only elementary integrations and the initial function remains the same for differential equations of the same order, making the procedure more straightforward.

Summary: This work explores the superposition of two well-known chaotic oscillators, finding highly chaotic solutions through numerical simulations and proving the existence and uniqueness of a super system using the Lipschitz condition. The qualitative properties of chaotic dynamics are described using Lyapunov exponent, eigenvalues, bifurcation, and Poincare maps, with validation of the superposition of chaotic systems using analog circuit design. Testing the randomness level and security features of the superposition chaotic system are conducted, and outcomes are presented in tabulated and graphical forms.
