Big data is a comprehensive result of the development Internet Things and information systems. Computer vision requires lot as basis for research. Because skeleton can adapt well to dynamic environment complex background, it used in action recognition tasks. In recent years, skeleton-based has received more attention field computer vision. Therefore, keypoints human skeletons are essential desc...

a simple, inexpensive and efficient method was used for extraction and determination of fexofenadine and levocetirizine with three–phase hollow fiber liquid-phase microextraction and high-performance liquid chromatography. several parameters influencing the extraction recoveries such as the nature of organic extraction solvent, ph of donor and acceptor phases, stirring rate, extraction time and...
