Embodiments of the present invention relate to water leakage detection. Data obtained by a smart electricity meter during a predefined time period is collected, where the smart electricity meter is associated with a water-consuming unit. Usages of certain electric appliances in the water-consuming unit during the predefined time period are determined based on the collected data. The electricity consumption of those appliances is correlated to water consumption. The legitimate water consumption of the water-consuming unit during the predefined time period is then determined based on the usages of the electric appliances.

Disclosed aspects relate to obtainability management in a social networking environment. A set of target recipients of a message may be detected in the social networking environment. A set of obtainability data may be ascertained with respect to the set of target recipients using the social networking environment. A message modification action may be determined using the set of obtainability data with respect to the set of target recipients. The message modification action may be performed in the social networking environment.

A method for optimizing migration efficiency of a data file over network is provided. Specifically, a total time of compression time of the data file, transfer time of the data file over the network, and decompression time of the data file, is minimized by adaptively selecting compression methods to compress each data block of the data file. For selecting a compression method for a data block, information entropy of the data block is analyzed, and a real status of computing and system resources is considered. Further, trade-off among the resource usage, compassion speed and compression ratio is made to calculate an optimized transmission solution over the network for each data block of the data file.

Adaptive compression and transmission for big data migration

A reusable asset packaging and consumption method and system that support consumption activities and variability point instances associated with asset types or artifact types. Generic consumption activities and variability point types for different asset types or artifact types and developed and stored in a repository. When an asset packager packages an asset, a needed activity is selected from the activities associated with the type of the asset. The activity, a variability point instance bound with the activity, and the context constraints, together with the artifacts is packaged into the asset package, where the asset package is then stored in a repository. During consumption, the asset consumer obtains the asset package, verifies the context, and executes the activity packaged in the asset, while specifying variability point values for the bound variability instance.
