A robotic casting machine provides for on-site, or near-site casting and automated production of cast components, such as concrete modular, volumetric building components. The method establishes \u201cpseudo-wires\u201d between, for example, routers, Layer-2 packet switches, or SONETSDH switches. Also provided is a method for operating an engine. The processor also includes multipliers and summer means all configured and arranged to perform the algorithm: Cos a+b=Cos a\xb7Cos b\u2212Sin a\xb7Sin bor the algorithm: Sin a+b=Cos b\xb7Sin a+Cos a\xb7Sin bfor use in the generation. This data typically contains identification data of the individual media items presently contained in that participant’s media library regardless of the individual media item’s source. Also provided is a method for maximizing a transmitted signal between sensors andor sources in a sensor network.
