摘要： A method and system for automatically aligning multiple MR volumes in whole-body MR scans is disclosed. The method and system are capable of automatic alignment of leg-volumes in whole-body MR scans that is insensitive to leg movement. In order to align upper and lower MR volumes, an automatic determination may be made that a junction between the upper and lower MR volumes is in a leg region. The lower MR volume is then divided into left and right regions, and each of the left and right regions are independently aligned with the upper MR volume. One of the left and right regions is then adjusted with respect to the other one to compensate for shifting of the legs with respect to each other.

摘要： The present invention is a method and an apparatus for predicting future travel times over a transportation network. In one embodiment, a method for predicting future travel times over a transportation network includes receiving a data point indicating a real-time volume of traffic on the link at a given time and updating a template representative of an observed traffic pattern on the link in accordance with the received data point. A future travel time over the link can then be estimated in accordance with the updated template. Thus, the template is able to adapt to dynamically changing traffic patterns, taking these changing traffic patterns into account when making predictions of future traffic patterns.

摘要： Apparatus and methods for identifying traffic patterns to web sites based on templates that characterize the arrival of traffic to the web sites are provided. Based on these templates, determinations are made as to which web sites should be co-located so as to optimize resource allocation. Specifically, web sites whose templates are complimentary, i.e. a first web site having a peak in arrival traffic at time t1 and a second web site that has a trough in arrival traffic at time t1, are designated as being candidates for co-location. In addition, the present invention uses the templates identified for the traffic patterns of web sites to determine thresholds for offloading traffic to other servers. These thresholds include a first threshold at which offloading should be performed, a second threshold that takes into consideration the lead time needed to begin offloading, and a third threshold that takes into consideration a lag time needed to stop all offloading of traffic to the other servers.

摘要： Resource allocations in stream data processing systems are performed to allocate the resources in a cost-effective manner by formulating the resource allocation problem as a linear program. For a problem with a single output, a backward algorithm or method is used that produces an optimal solution in linear time. For a problem with multiple outputs and the network has a tree structure, a backward shrink algorithm or method is used to provide an optimal solution in linear time. These algorithms are fully distributed, they require only local exchange of parameters between neighboring nodes, and are adaptive to the dynamic changes in network conditions and flow rate fluctuations.
