摘要： Predicting battery drain time that would be caused by a new application being considered for a smartphone. The battery drain time prediction is based on the type of smartphone and type of battery, the battery age, and hardware subunit usage levels. The system may provide a watchdog service for monitoring and storing data of user's smartphone which may then be used to create a user profile. Upon receiving a request for a battery drain time prediction, the system matches the profile of the user's smartphone with an existing profile in the repository having pre-installation and post-installation data for the application being considered. The matching user profile can be used to predict battery drain time that will be caused by the new application.

摘要： A method, system, and computer usable program product for parallel data redundancy removal are provided in the illustrative embodiments. A plurality of values is computed for a record in a plurality of records stored in a storage device. The plurality of values for the record is distributed to corresponding queues in a plurality of queues, wherein each of the plurality of queues is associated with a corresponding section of a Bloom filter. A determination is made whether each value distributed to the corresponding queues for the record is indicated by a corresponding value in the corresponding section of the Bloom filter. The record is identified as a redundant record in response to a determination that each value distributed to the corresponding queues for the record is indicated by a corresponding value in the corresponding section of the Bloom filter.

摘要： A method is disclosed for facilitating visualisation of status data in an electronic system. The status data comprises metadata including a plurality of information context categories. The status data also comprises data nodes, each data node including specific instances of a respective context category. The method starts with selecting possible data combinations and permutations of the information context categories, each permutation defining a respective hierarchy. For each permutation, information content of data for each node of the respective hierarchy is estimated and an informative tree and total entropy for all informative nodes are found. The permutation and the informative tree that has the lowest total entropy are then presented to the user.
