Metasurfaces comprising arrays of film-coupled, nanopatch antennas are a promising platform for low-energy, all-optical switches. The large field enhancements that can be achieved in the dielectric spacer region between the nanopatch and the metallic substrate can substantially enhance optical nonlinear processes. Here we consider a dielectric material that(More)
Hyperspectral remote sensing image (HSI) consists of hundreds of bands that contain rich space, radiation and spectral information. The high-dimensional data can also lead to the course of dimensionality problem making it difficult to be used effectively. In this paper, we proposed a manifold learning algorithm to reduce the dimensionality for HSI data. For(More)
As social network is becoming widely used, the problem of protection of user's privacy has caused heated debate. It is necessary to let users know who would propagate or leak their personal information, and we define those people as vulnerable friends. Most existing approaches are either personal information based or users' influence based. In this paper,(More)
The paper reveals a trend of substituting PC with thin clients. Features and application demand of thin clients are investigated. A comprehensive evaluation system is established, which takes factors including hardware, remote concentrated management system, peripheral compatibility, performance, reliability, virtualization platform compatibility and energy(More)
