Nonlinear Filtering With Sample-Based Approximation Under Constrained Communication:Progress, Insights and Trends

IEEE/CAA Journal of Automatica Sinica 2024年第07期11卷 1539-1556页

The nonlinear filtering problem has enduringly been an active research topic in both academia and industry due to its ever-growing theoretical importance and practical *** main objective of nonlinear filtering is to infer the states of a nonlinear dynamical system of interest based on the available noisy measurements. In recent years, the advance of network communication technology has not only popularized the networked systems with apparent advantages in terms of installation,cost and maintenance, but also brought about a series of challenges to the design of nonlinear filtering algorithms, among which the communication constraint has been recognized as a dominating concern. In this context, a great number of investigations have been launched towards the networked nonlinear filtering problem with communication constraints, and many samplebased nonlinear filters have been developed to deal with the highly nonlinear and/or non-Gaussian scenarios. The aim of this paper is to provide a timely survey about the recent advances on the sample-based networked nonlinear filtering problem from the perspective of communication constraints. More specifically, we first review three important families of sample-based filtering methods known as the unscented Kalman filter, particle filter,and maximum correntropy filter. Then, the latest developments are surveyed with stress on the topics regarding incomplete/imperfect information, limited resources and cyber ***, several challenges and open problems are highlighted to shed some lights on the possible trends of future research in this realm.

Compound Shenhua Tablet, a medicine comprising seven herbs, is employed in treating Ig A nephropathy. This study aimed to meticulously analyze its chemical composition. Based on a list of candidate compounds, identified through extensive literature review pertinent to the tablet's herbal components, the composition analysis entailed the systematic identification, characterization,and quantification of the constituents. The analyte-capacity of LC/ESI-MS-based and GC/EI-MS-based assays was evaluated. The identified and characterized constituents were quantified to determine their content levels and were ranked based on the constituents' daily doses. A total of 283 constituents, classified into 12 distinct categories, were identified and characterized in the Compound Shenhua Tablet. These constituents exhibited content levels of 1-10 982 μg·g-1, with daily doses of 0.01-395 μmol·d-1. The predominant constituents, with daily doses of ≥ 10 μmol·d-1, include nine organic acids（citric acid, quinic acid, chlorogenic acid, cryptochlorogenic acid, gallic acid, neochlorogenic acid, isochlorogenic acid C, isochlorogenic acid B, and linoleic acid）, five iridoids（specnuezhenide,nuezhenoside G13, nuezhenidic acid, secoxyloganin, and secologanoside）, two monoterpene glycosides（paeoniflorin and albiflorin）, a sesquiterpenoid（curzerenone）, a triterpenoid（oleanolic acid）, and a phenylethanoid（salidroside）. Additionally, there were 83, 126, and55 constituents detected in the medicine with daily doses of 1–10, 0.1–1, and 0.01–0.1 μmol·d-1, respectively. The combination of the LC/ESI-MS-based and GC/EI-MS-based assays demonstrated a complementary relationship in their analyte-capacity for detecting the constituents present in the medicine. This comprehensive composition analysis establishes a solid foundation for further pharmacological research on Compound Shenhua Tablet and facilitates the quality evaluation of this complex herbal medicine.

通过模拟叶栅研究二次流对端区多排扇形孔的影响,并在平板气膜实验台上安装涡流发生器生成流向涡,模拟叶栅端区二次流对壁面气膜冷却的作用,研究流向涡强度对多排扇形孔冷效的影响。结果表明:当涡流强度增加,流向涡对气膜冷效的影响和气膜偏斜程度增加。气膜的叠加效应可以提高第二排和第三排气膜冷却效率,弥补流向涡造成后排气膜冷却效率的降低。进气角会影响叶栅通道涡强度,导致端壁气膜发生变形,冷效分布发生改变。边界层会造成二次流强度减弱,导致压力面侧的气膜冷效得到增强。
