Object tracking under complex circumstances is a challenging task because of background interference, obstacle occlusion, object deformation, etc. Given such conditions, robustly detecting, locating, and analyzing a target through single-feature representation are difficult tasks. Global features, such as color, are widely used in tracking, but may cause(More)
—In this article, a novel wideband planar monopole antenna for applications in 2.4 GHz Bluetooth and UWB bands is presented and investigated. The low-profile antenna comprises an approximate rectangle patch for covering the UWB band (3.1 ∼ 10.6 GHz). A lower pass band, 2.4 GHz Bluetooth band (2.4 ∼ 2.484 GHz), can be realized by adding a pair of U-shaped(More)
We propose an effective scheme of shortcuts to adiabaticity for generating a three-dimensional entanglement of two atoms trapped in a cavity using the transitionless quantum driving (TQD) approach. The key point of this approach is to construct an effective Hamiltonian that drives the dynamics of a system along instantaneous eigenstates of a reference(More)
—In order to enable multi-scale urban visualization, multiple model representations at different levels of detail (LoDs) need to be produced (like by generalization) in advance or on the fly. At local scale, building groups are involved and at least medium LoD is needed in terms of visual perception. Motivated by such demands, this article proposes a novel(More)
The ever-growing capacity and continuously-dropping price have enabled flash-based MLC SSDs to be widely deployed as large non-volatile cache for storage systems. As MLC SSDs become increasingly denser and larger-capacity, more complex and complicated Error Correction Code (ECC) schemes are required to fight against the decreasing raw reliability associated(More)
A novel planar antenna with WiMAX and WLAN band-notched characteristics is presented for ultra-wideband (UWB) applications. The UWB antenna consists of a staircase-shaped radiating element, a microstrip feedline and a modified ground plane. To realize WiMAX band-notched characteristic, a pair of hook-shaped slots is etched on the radiating element. Two(More)
