Tantalum-based ceramics are suitable for use in thermal protection systems. The cross-braces are received through cross-brace receiving openings in the tubular legs, and the cross-braces are bolted together within the legs by nut and bolt assemblies. The predicted behavior of the leader is then copied for the followers. Subsequent instructions can then be prevented from progressing through the pipeline. The nonconductive coating may comprise a medical grade silicone of a specified thickness. A method of manufacturing a smart panel includes spraying a coating solution including a thermochromic material and a silicon oxide on a surface of a transparent substrate, and drying the coating solution to form a coating film on the surface of the substrate.
