High false alarm rates on active sonar systems in shallow waters is a well known problem which may be a limiting factor for the sonar performance. One way to reduce the false alarm rate is through supervised learning and machine learning algorithms applying relevant classification features. Here we propose backscatter intensity as a classification feature. It is calculated from a topographical map...
Anti-submarine warfare (ASW) operations in littoral waters can be challenging, especially in areas with topographical features and man-made objects that leads to increased false alarm rates. To maximize training benefit from operations in these areas, an efficient evaluation system that is able to visualize and analyze the total volume of sensor and environmental information is required in order to...
In type-II superconductors, increasing applied magnetic field penetrates gradually in the form of magnetic vortices. It is of great interest to understand the dynamics of magnetic flux in different superconducting materials, as this phenomenon can severely limit the performance of superconductors in applications. YBa2Cu3O7−x (YBCO) is an important high-temperature superconductor, but until recently,...
