Based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. In the process, stress and displacement fields are expanded according to the Fourier series along the axial and circumferential coordinates. From ...

Most research on panel data focuses mean or quantile regression, while there is not much about regression methods based the mode. In this paper, we propose a new model named fixed effects modal for in which how conditional mode of response variable depends covariates and employ kernel-based objective function to simplify computation. The proposed can complement regressions provide better centra...
