In one embodiment, a set of temporally related call detail records associated with at least one user of a wireless communication network is analyzed. A set of base stations accessed during at least one call associated with the set of temporally related call detail records is identified based on the analysis of the records. At least one road segment of a road network within a threshold distance to each of the set of base stations is identified. A set of mobility information for the at least one user indicating that the at least one user traversed the at least one road segment is stored based on identifying the at least one road segment.

Abstract: Methods and arrangements for caching video object portions. A request for stand-alone content in a video object is received, the content neither being cached nor being adjacent to a cached video object portion, and a first portion of the video object is cached. A value is assigned to the first video object portion. A subsequent request for content in the video object is received, the subsequent request corresponding to access to the first video object portion and a second, uncached portion of the video object. The value of the first video object portion is updated. For the second video object portion, an amount to cache and a value are determined.

Abstract: Methods and arrangements for determining a layout and dimensions of a wind farm. A three-dimensional wake model for a wind farm is generated, and a positioning and dimensioning model for turbines of the wind farm is developed based on the three-dimensional wake model.

Abstract: Methods and arrangements for video delivery preparation. A video, being accessible online, is displayed at an interface in response to a user request. A relative probability of video access by the user with respect to at least two other online-accessible videos is qualitatively determined. An ordered prediction set is created with respect to the other videos. The other videos are prepared incrementally based on the prediction set, so that the user is able to access and view the videos. The preparing includes preparing a first one of the other videos over a first time period and a second one of the other videos over a second time period, wherein at least a portion of the first time period is coincident with at least a portion of the second time period. An element is displayed at the interface which provides a connection to at least one of the other videos.

Abstract: Methods and arrangements for facilitating virtual machine migration across data centers. A virtual machine is designated for migration from a first data center to a second data center, the virtual machine including a real identifier. A pseudo identifier is assigned to the virtual machine, and the pseudo identifier is mapped to the real identifier at a controller of the first data center. The real identifier is replaced in a data packet with the pseudo identifier for a routing task. Communication is maintained between the controller of the first data center and a controller of the second data center, and the controllers are synchronized to update a correct location of the virtual machine. The virtual machine is migrated from the first data center to the second data center.
