This book shows how Lie group and integrability techniques, originally developed for differential equations, have been adapted to the case of difference ones. Each of the eleven chapters is a ...

Abstract: In this paper, we propose two kinds of improved nested arrays for direction of arrival (DOA) estimation, which are obtained by rearranging physical sensors of the prototype nested array.

When a delicate object crashes onto the floor, most people expect it to shatter into several pieces. What they might not know, however, is that the sizes of those fragments—whether from a broken plate ...

Abstract: The laser powder-bed fusion (LPBF) technique is evaluated to manufacture monolithic antennas in metal, which permits the production of metallic antennas reducing the conventional procedure ...
