This letter presents a dual-band and circular polarization microstrip antenna, with a dual-frame patch and slots loaded on its external sides. Based on the multimode resonant theory, a dual-band operation at 1.616 GHz and 2.492 GHz for CNSS applications is realized by the capacity coupling between the frames inside and outside through four-arm conductive bridges. The perturbation is introduced in...
In order to take domain expert knowledge as a supplement of the machine "intelLigence", a High-Level-Concept-based framework (HLC) for heuristic search is proposed. HLC has domain experts actively generaLize their own psychological feeLings about image features into high-level concepts, then write down them in descriptors, and make the domain high-level concepts enter a heuristic search...
Partial discharge (PD) detection has been used in assessment of condition reliability of electrical insulation in high voltage equipment such as power station. Unfortunately, PD signals took during condition monitoring are often corrupted with excessive interference. The challenge to effectively and accurately determine and extract the pure PD signal from the large amount of noise still remains. The...
