To overcome the technological and economic obstacles of amorphous indium-gallium-zinc-oxide (a-IGZO)-based display backplane for industrial production, a clean etch-stopper (CL-ES) process is developed to fabricate a-IGZO-based thin film transistor (TFT) with improved uniformity and reproducibility on 8.5th generation glass substrates (2200 mm × 2500 mm). Compared with a-IGZO-based TFT with back-channel-etched...
Flooding is a simple technique in wireless sensor networks where a source or node sends packets through every outgoing link, which is similar to broadcasting. A pure flooding is quite reliable, however, it is clearly too expensive. Data packets are being transmitted via all nodes that are all required to forward the packets exactly once. In this paper, we introduce a new flooding protocol based on...
Addressing the extremely high reliability is a critical problem of wireless control system in actual industrial applications. In this paper fully considering the characteristics of the wireless network transmission and industrial automation application, a grouping TDMA access approach based on multiple access points is proposed. The main idea is that: redundant multiple access points are applied in...
For the wavelet transform has limitations in extract features of the edge of images, a method of the facial expression recognition is proposed that using curvelet transform to extract features of the edge of images. The curvelet transform can get more representation of sparse images than the wavelet transform on the representation of the singular of the edges of image curve. The curvelet coefficient...
