Heterogeneous radar sensor networks (HRSNs) are gaining popularity due to the superior detection performance compared to conventional homogeneous radar sensor networks. In this paper, under the assumption that radar sensors perform differently in target detection and energy management, we propose optimized energy allocation scheme based on different fusion approaches for both single moving targ...

Weak-signal detection and single-particle selection from low-contrast micrographs of frozen hydrated biomolecules by cryo-electron microscopy (cryoEM) presents a practical challenge. Cryo-EM image contrast degrades as the size of biomolecules of structural interest decreases. When the image contrast falls into a range where the location or presence of single particles becomes ambiguous, a need ...

Energy detection is one of the popular spectrum sensing technique for cognitive radio. Better performance can be obtained by cooperative detection, but only when cognitive radios did not have different geographic locations and channel environment. To avoid this drawback, the paper presents an improved energy-based weighted cooperative spectrum sensing method which allows to achieve higher detec...
