    摘要： A computer data storage system receives a plurality of data units from a host computer. The system stores the data units in a buffer memory. The system generates a plurality of data segments comprising a plurality of subsets of the plurality of data units. The system receives a plurality of dataset information tables (DSITs) corresponding to the plurality of data segments. The system appends the plurality of DSITs to the respectively corresponding plurality of data segments, to create a plurality of datasets stored in the buffer memory. The system determines a number of datasets stored in the buffer memory, exceeds a threshold value. And in response to determining the number of datasets, of the plurality of datasets stored in the buffer memory, exceeds the threshold value, the system stops the appending the plurality of DSITs to the respectively corresponding plurality of data segments.

    摘要： A method, system and computer program product for presenting content (e.g., advertisements) to vehicle occupants. An image of the occupants of the vehicle is obtained. The vehicle occupants, such as the driver, are then identified from the image. After obtaining the driving history of the driver, which includes any information that indicates a risk posed to the driver in not paying attention to the road, a risk degree of the driver getting into an accident from viewing content on the electronic billboard is assessed. A “watch ability” of the vehicle occupants to watch content is calculated, based, at least in part, on the driver's risk degree. If the value of the watch ability exceeds a threshold value, then the content preferences of the vehicle occupants are obtained which are used to determine the contents to be presented on the electronic billboard which are targeted to the vehicle occupants.

    摘要： In an approach to improve file recall between storage devices by optimizing file recall for multiple users. Embodiments of the present invention obtain one or more similarities among one or more users based on one or more usage points and divide the one or more users into a plurality of clusters based on a content of the one or more usage points. Further, embodiments select a cluster from the plurality of clusters based on cluster importance, and select the content used by more than a predetermined percentage of the weighted users pertaining to the selected cluster as an automated recall subject. Additionally, embodiments recal one or more selected content from a secondary storage device to a primary storage device.
