A conveyor system for processing items on which radio frequency identification tags are disposed includes a frame, a conveyor disposed movably on the frame and that conveys items through a path of travel, each item having at least one respective radio frequency identification tag disposed thereon, at least one first antenna, at least one second antenna, a radio frequency receiver, and a processor. The effectiveness of targeted in furnace injection, in fuel introduction and in furnace introduction of slag andor corrosion andor plume control chemicals are determined, as are the effectiveness of targeted in furnace injection, in fuel introduction and in furnace introduction of combustion catalysts. This allows the NIDS to automatically determine network topology, update itself as hardware in the network is added or changed, and promptly take automated service actions in response to detected network intrusions. The method partitions the intermediate video stream into a plurality of video chunks, where each video chunk corresponding to a portion of video data of the video stream. The circuitry is flexible to allow different matrix sizes, speed grades, and target frequencies without recompilation. If the calculated probability is greater than a first threshold, an indication that the target phoneme was pronounced correctly is output; if less than a first threshold, an indication that the target phoneme was pronounced incorrectly is output.
