The present invention provides a process for making a complex metal oxide comprising the formula AxByOz. According to an example embodiment, a multicast management frame frame) may be transmitted to identify a scheduled multicast data transmission to one or more receiver nodes in a wireless network. An incident laser beam reflects off of the sample channel walls and through the sample in the channel, thereby generating backscattered reflections that create interference fringe patterns. The first computer is programmed for operation on the first locomotive. In other words, when being activated, the vehicle light will produce light whose form depends on orientations of the refraction elements of the light source units. Additionally, this inventive induction heating system may further comprise a controller circuit in the second article for detecting an eddy current in the coil and operating a switch to turn the alternating electrical current off when no eddy current is detected in the coil.
