A Ni-doped TiO 2 photocatalyst was prepared by polyol method and characterized by ICP-MS, XRD, N 2 adsorption–desorption, SEM, and UV–vis techniques. The effect of preparational parameters such as reduction temperature and reduction time on the degradation of xylene vapor in air under UV light illumination was evaluated. The results revealed that the photocatalytic activity of TiO...
We propose a fast mode decision algorithm to reduce the computational complexity of adaptive GOP structure (AGS) in the scalable extension of H.264/AVC. AGS can improve the coding efficiency of the scalable extension of H.264. It, however, needs to perform motion-compensated temporal filtering (MCTF) of all possible GOP sizes, leading to much higher computation than the fixed GOP structure. In our...
