Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 3,   Pages 327-354 doi: 10.1631/FITEE.2200366

Abstract: The is a highly energy-intensive, highly polluting, and extremely complex reactor in the . are a key technology for predicting molten iron quality indices reflecting energy consumption and operation stability, and play an important role in saving energy, reducing emissions, improving product quality, and producing economic benefits. With the advancement of the Internet of Things, big data, and artificial intelligence, data-driven in es have attracted increasing attention from researchers, but there has been no systematic review of the data-driven in the . This review covers the state-of-the-art studies of data-driven technologies in the . Specifically, we first conduct a comprehensive overview of various data-driven soft sensor modeling methods (multiscale methods, adaptive methods, , etc.) used in ironmaking. Second, the important applications of data-driven in ironmaking (silicon content, molten iron temperature, gas utilization rate, etc.) are classified. Finally, the potential challenges and future development trends of data-driven in ironmaking applications are discussed, including digital twin, multi-source data fusion, and carbon peaking and carbon neutrality.

Abstract: A series of novel 6-( -butyl)-8-fluoro-2,3-dimethylquinoline carbonate derivatives were designed and synthesized. Bioassay results showed that some of them exhibited good activity against ( ). It was found that the compound (benzyl (6-( -butyl)-8-fluoro-2,3- dimethylquinolin-4-yl) carbonate) possessed good activity against whatever protective activity (10 mg·L ) or curative activity (25 mg·L ), which was better than that of control tebufloquin. In addition, the frontier molecular orbit results revealed that the compound held higher activity against when the total energy was low and the ClogP was high, which may provide useful information for further design novel fungicides.
