Abstract: A computer-implemented method includes receiving a set of constraints for an antenna having nodes of a phased array for receiving and/or transmitting a radiation signal, including a shape and size of the antenna, a frequency range for the radiation signal, and a view sector. The method includes receiving a set of thresholds including a threshold for a beam width of a central beam of the radiation signal and a threshold for interference associated with radiation outside of the central beam of the radiation signal. The method includes determining a first set of locations of the nodes based on the set of constraints and thresholds, determining an adjustment for the first set of locations in accordance with the set of thresholds, and determining a final set of locations of the nodes based on the adjustment to minimize a node count and achieving an optimized operation of the antenna.

Abstract: Techniques for monitoring a machine for significant deviations from normal operations include collecting, at a first processing element, sensor data about the machine. The first processing element performs narrowband frequency domain processing to determine a segment of sensor data that indicates a deviation from normal operations that exceeds a threshold deviation. A message including the segment of sensor data is sent to a second processing element. In response to receiving the message, the second processing element performs different narrowband frequency domain processing to determine whether the deviation from normal operations is significant for maintaining the machine. If the deviation from normal operations is determined to be significant for maintaining the machine, then the deviation is reported to cause the machine to be maintained.
