Hyperspectral imaging technique has been widely used in remote sensing, surveillance in agriculture, environmental monitoring, etc. However, spectral information alone cannot well discriminate objects made with the same material. Conventional methods either fuse complementary information from other sensors or mine relevant information from the original hyperspectral data to improve the recognition...
Sequences of mcyJ gene of 62 Microcystis strains from different locality, and one Anabaena strain, two Planktothrix agardhii strains were analyzed. The phylogenetic tree of mcyJ was constructed. The result showed that the variation of mcyJ genotype in Microcystis had no relationship with its locality or species; genetic distance of mcyJ between Microcystis and Anabaena, Planktothrix agardhii was obvious...
The properties of tapered-cladding single-mode hemispherical fiber micro-lenses whose radius is larger than twice of the core radius of the fiber are investigated by Monte Carlo simulation. The radial field distribution of the fiber is expressed as a Gaussian distribution. Simulation results show that the least confusion spots and the maximum axial intensity spots are not located at the focal plane...
