In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

This study presents the continuous element formulation for analyzing the dynamic behavior of ring-stiffened cylindrical shells made of FGM material. Based on the solutions of the shell differential equations, the dynamic stiffness matrix is calculated. A procedure to assembly cylindrical and annular shells is introduced in order to compute the natural vibrational frequencies of FGM ring-stiffened cylindrical shells.

In this paper, geometrical nonlinear flutter analysis of functionally graded carbon nanotubes reinforced composite plates is presented. The governing equations of the system are obtained using the Mindlin plate theory and von Karman geometric nonlinearity. The linear piston theory is utilized to determine the aerodynamic pressure. Applying the Hamilton principle, equations of motion of a system are derived in the matrix form, and then the finite element method is used to obtain the discretized equations.
