    Abstract: Provided are an intelligent decision-making and control method and system for a microchemical reaction in stepwise sulfidation of a high arsenic-contained waste acid from copper smelter. Microchemical information from the real-time monitoring module is acquired by the intelligent decision-making module. A stage combination for a sulfidation reaction is determined based on a concentration of arsenic in raw waste acid. A total amount of arsenic and an amount of hydrogen sulfide to be added at a first stage are calculated based on a valence state and concentration of arsenic in and a flow rate of inflow at the first stage, and a total amount of arsenic and an amount of hydrogen sulfide to be added at a second stage are calculated based on a valence state and concentration of arsenic in and a flow rate of inflow at the second stage.

  • Patent number: 11429581
    Abstract: A method and/or system for managing a database that stores space-time context objects is provided. The system receives a query range in a multi-dimensional space. The system maps the query range into a set of fragments of a space-filling curve that fills the multi-dimensional space in all dimensions of the multi-dimensional space. The system uses each mapped fragment in the set of mapped fragments as a key to query the database for space-time context objects that are mapped to the space-filling curve. The system queries the database by identifying one or more context objects that intersect the mapped fragment at the space-filling curve.

    Abstract: A system, method and computer program product for retrieving trajectory data from huge datasets. In the method, there is received, at a processor device, a user query including a request for displaying trajectory data at a user device. From the user query, a query type and a current map visualization scale setting (mapscale) for visualizing the trajectory data on the user device display is determined. Then, responsive to a user query type and the determined mapscale setting, a corresponding reference level is selected. Based on the selected reference level, there is accessed from a memory storage device a data set of compressed trajectory data. This compressed trajectory data set is communicated to the user device, for presentation on the user device display. In one aspect, the system and method is adaptive, enabling storage and retrieval of trajectory data according to various degrees of visualization or granularity.
