Abstract: Operational frequency selection is a critical spot for ensuring high-frequency (HF) communication’s optimal quality, thus accurate prediction of usable frequency is essential to HF ...

Estimating the number of triangles in a graph is a fundamental problem and has found applications in many fields. This problem has been widely studied in the context of graph stream processing.

Abstract: For low-frequency source localization with a small-aperture acoustic array, we propose a high-resolution localization algorithm based on complex Wishart prior. The algorithm, named ...

During cardiac arrhythmia, the heart frequency is an important physiological parameter that can be identified by analyzing electrocardiogram (ECG) signals. However, the accuracy of the frequency ...
