A method, system, and computer program product to manage a network comprising a plurality of interconnected components are described. The method includes obtaining a set of all the components that are part of the network over time, and identifying one or more repeating patterns of components among the set of all the components as corresponding lower-level definitions to generate a hierarchical set of all the components. The method also includes obtaining time-varying information regarding topology and operational values within the network, and creating a representation of the network at a set of times based on the hierarchical set of all the components and the time-varying information.

Embodiments of the present disclosure allow accuracy of prediction of pollution to be improved. In operation, a prediction of pollution in a future time period is determined. The prediction of pollution indicates predicted data related to a pollution index. Then, matching historical data for the predicted data is determined from historical data related to the pollution index. The matching historical data is obtained in a historical time period corresponding to the future time period. Based on the matching historical data, the prediction of pollution is refined.

Pollution prediction

A method for determining a source of pollutant emissions for a selected area includes: mapping a grid onto a representation of the selected area; collecting monitoring data for the selected data; from the monitoring data, assigning air pollution values and weather values to each cell in the grid using an interpolation method to estimate values for gap cells; re-sizing the grid to mitigate the influence of atmospheric turbulence on the air pollution values; and using weather factor separation to minimize the influence of weather from the air pollution values, resulting in air pollution values that reflect the net pollutant emissions for the selected area.

This disclosure provides a computer-implemented method for data storage in a non-relational database. The method comprises receiving a data item to be inserted into a table in the non-relational database. The method further comprises determining a dynamic data section and a static data section of the received data item. The method further comprises in response to the static data section not existing in the static data storage area, storing the static data section in the static data storage area. The method further comprises storing the dynamic data section in the dynamic data storage area.

Data storage with improved efficiency

A method of setting retransmission time of an application client during virtual machine migration includes predicting migration memory size required by a virtual machine to be migrated based on historical access log of at least one application and memory log of the virtual machine to be migrated; computing available migration bandwidth of a host of the virtual machine to be migrated; computing virtual machine migration time based on the predicted migration memory size required by the virtual machine to be migrated and the available migration bandwidth of the host; and setting retransmission time of the application client based on the virtual machine migration time.
