In this paper, we analyze the radar cross section (RCS) of an integrated mast and present the optimized mast shape for RCS reduction.The RCS is simulated using commercial electromagnetic (EM) software based on the shooting and bouncing rays (SBR) method and the diffraction fields at the edges are also considered.Threat old taylor whiskey 1933 price
In this paper, the hydrodynamic characteristics of a rim-driven thruster (RDT) behind the hull of an underwater vehicle are investigated.The studied underwater vehicle is the benchmark DARPA (Defense Advanced Research Projects Agency) suboff model, with and without full appendages.In order to verify and validate the numerical model, a grid sensitiv
Abstract: For transverse isotropic fast formations, the evaluation method of the least horizontal principal stress by using logging data is an important unresolved issue.An innovative method is proposed to solve this problem by pot drum derivation of five independent stiffness coefficients (C11, C33, C44, C66 and C13) in this kind of formation.Base
