Method of non-destructive control of thickness and internal defectivity of the walls of metal pipe by S. A. Zolotarev, P. S. Savenia, K. A. Zhukov, M. A. Sednina

“…The possibility of an accurate estimation of the pipe wall thickness measured directly from the reconstructed image of the pipe, reconstructed from only a few X-ray projections made in a limited viewing angle, is discussed. Since the effects of radiation scattering and X-ray beam hardening distort up to 50 % of the primary radiation, ignoring these effects leads to blurred images, strong artifacts, and inaccurate sizing. …”

Mutual Coupling Effects for Radar Cross Section (RCS) of a Series-Fed Dipole Antenna Array by H. L. Sneha, Hema Singh, R. M. Jha

“…It is shown that the mutual coupling affects the antenna pattern (and hence RCS) significantly for larger scan angles. Further it is inferred that the RCS of phased array can be optimized by (i) reducing the length of the dipole, (ii) termination of the isolation port of the coupler with a suitable load, and (iii) using suitable amplitude distribution.…”
