The present work deals with the semi-analytical assessment of three-dimensional stress fields in circular cylindrical symmetrically and unsymmetrically laminated cross-ply shells undergoing different transverse loads. Starting from a closed-form plane-strain analysis innermost regions shell, elasticity solution is upgraded by higher-order displacement-based approach which enables developed meth...
Cylindrical shells exhibit a dense frequency spectrum, especially in the lowest frequency range. In addition, due to the circumferential symmetry, frequencies occur in pairs. So, in the vicinity of the lowest natural frequencies, several equal or nearly equal frequencies may occur, leading to multiple internal resonances. The aim of the present work is to investigate the dynamic behavior and st...
A method for the removal of ionospheric effects from single-frequency non-GPS radio navigation data through the use of data collected from a single collocated dualfrequency GPS receiver is presented. The method uses a local ionosphere model to estimate the total electron content (TEC) along any line of sight that differs from the GPS satellite lines of sight. Two novel models are investigated, ...
