Application of an improved ISODATA method to pipeline leak detection
Increasingly serious leak problem in pipeline transportation has not only affected the operation of pipelines but also caused loss of precious resource and environmental damage. Based on the analysis of the occurrence of negative pressure waves and the unsupervised learning of pattern recognition, the Interactive Self-organizing Data Analysis Technique

Adaptive Subarray Partitioning for Large-Scale Phased Arrays Using ISODATA
ABSTRACT Phased array antennas, known for their high directivity and low sidelobe levels, are widely used in radar and communication systems. As the array size increases, controlling each element individually becomes increasingly complex and costly. To address this challenge, subarray partitioning is an effective solution. Traditional
