A gold-nanoparticles (Au NPs)-Rhodamine 6G (Rh6G) based fluorescent sensor for detecting Hg(II) in aqueous solution has been developed. Water-soluble and monodisperse gold nanoparticles (Au NPs) has been prepared facilely and further modified with thioglycolic acid (TGA). Free Rh6G dye was strongly fluorescent in bulk solution. The sensor system composing… (More)
In the finite element method (FEM), the matrix equation can be solved either using a direct elimination method or an iterative method. The conjugate gradient (CG) is a common-used iterative method. But there are several limits in its application. In order to overcome the disadvantages, a preconditioned conjugate gradient (PCG) method based on the incomplete… (More)
Conformal antennas have got a wide application in the modern communication systems, Planar monopole antenna is one typical conformal antenna. In this paper, a broadband omnidirectional planar monopole antenna is presented, and the influence of structure parameters on its electric characteristics is investigated.
To better reduce redundant data and improve the completeness and conciseness of existing feature data, this articleapplies the theories of fidelity and quantum computation to feature fusion and proposes a novel quantum-inspired method based on maximum fidelity.In contrast tocurrentquantum-inspired feature fusion methods,this method uses the fidelity between… (More)
