The sloshing behavior of systems is influenced by different factors related to the liquid level and tank specifications. Different approaches are applicable for the assessment of sloshing behavior in a tank. In this paper, a new numerical model based on the differential quadrature method and boundary element approaches is adopted to investigate the sloshing behavior of a tank with an elastic thin-walled beam. The model is developed based on small slope considerations of the free surface. The main assumption of fluid modeling is homogeneity, isotropy, inviscid, and only limited compressibility of the liquid. Indeed, the formulation is represented based on the reduced-order method and then is employed for simulating the coupling between structure and fluid in symmetric test cases. The results are verified with the ANSYS and literature for symmetric rigid structural walls and then the code is employed to study the behavior of fluid-structure interaction in a symmetric tank with new and efficient immersed structure.

This paper deals with the problem of dissipative filtering for a class of nonlinear singular Markovian Jump systems (SMJSs) with time-varying delays. Our consideration is centered on the design of a mixed filter that can contain both mode-dependent and mode-independent filters in a unified framework. By using a delay-decomposition approach and constructing a mode-dependent stochastic Lyapunov–Krasovskii functional, sufficient delay-dependent conditions are derived in terms of linear matrix inequalities, which guarantee the considered nonlinear SMJSs to be stochastically admissible with a dissipativity performance [Formula: see text]. Based on the conditions, the existence conditions and parameters of the desired filter are obtained. Two numerical examples are given to illustrate the reduced conservatism and the effectiveness of the proposed methods.

Food security concerns people’s livelihood. Under the background of urban-rural integrated development and accelerated rural revitalization, high-quality grain production is the foundation of agricultural modernization, and grain industrialization is the only way to realize agricultural modernization. How to produce high-quality food has been widely concerned. The goal of this paper is to establish the modernization of the entire industrial chain of food production, laying a foundation for comprehensive revitalization for the high-quality development of the food industry and the realization of food industrialization. From the perspective of rural revitalization, the high-quality development model of China’s grain industry is studied. This paper gives new progress and new achievements in the high-quality grain development model, which requires a more precise and internally driven policy support system. The high quality of the food industry will help to improve the level of food industrialization, expand the economy of the food industry, accelerate the process of agricultural modernization, and ultimately realize rural revitalization and an all-round well-off society in rural areas.
