A novel algorithm for event matching of publish /subscribe systems is presented. To use the filtering abilities of attribute names and values synthetically, a double-deck tree structure is proposed. For the first deck, the proposed algorithm builds a tree structure by using the attribute names. All subscriptions are partitioned into the nodes of the first deck tree according to the attribute contained...
A novel cooperative tracking method for multiple vessels is presented. The dynamics of underactuated vessels are described firstly, we are especially interested in situations for which there are environmental disturbances induced by wind, waves and ocean currents. Then tracking errors are analyzed and a sliding mode tracking controller is designed to solve the consensus problem of underactuated vessels,...
Starting from the demand for antagonizing anti-radiation weapons of fire control radar, the principle of intermittent target tracking of fire control radar network is introduced, and the fire control radar network simulation system based on high level architecture is designed, the functional structure of the simulation federation and the simulation process of federal members is analyzed. In order...
The strong electron-accepting ability of transition metal ions enables them to catalyze the oxidation of S(IV) to S(VI) in solution. This reaction has been applied in many fields, such as flue gas desulfurization, hydrometallurgy, atmospheric chemistry, and chemical engineering. To understand the characteristics of the catalysis, this paper reviews the status of research on this reaction in the different...
To cope with the deterioration of the atmospheric environment and to examine flue gas desulfurization for recyclable resources, a flue gas desulfurization technology using scrap iron was developed, which achieved better desulfurization performance in a small-scale experimental study. In addition, economically valuable by-products can be produced from the proposed flue gas desulfurization. Based on...
