Abstract:
An apparatus and a method for efficiently processing multiple continuous aggregate queries in data streams are provided. The apparatus includes a first operation result sharing unit configured to generate a common window including first aggregate areas, and store a first operation result of each of the multiple continuous aggregate queries for each of the first aggregate areas. The apparatus further includes a second operation result sharing unit configured to determine a second aggregate area including at least one of the first aggregate areas, and store a second operation result of each of the multiple continuous aggregate queries for the second aggregate area. The apparatus further includes a query processing unit configured to process the multiple continuous aggregate queries based on the first operation result and the second operation result.
Abstract:
Disclosed is a user interface which enables mark based interaction for images. The present disclosure relates to a user interface which enables mark based interaction for images, the images comprising a volume which is a three-dimensional image and slices which are two-dimensional images, each of which represents a cross section of the volume. At least two of the images each include the same visual mark for identifying at least one common region of interest. The user interface comprises: an input unit for receiving a user input associated with the same visual mark included in one of the images; and at least one component for enabling the interaction for the images including the same visual mark associated with the user input.
Abstract:
A method of searching a pattern of sequence data, includes setting an interest pattern model comprising a length of an interest pattern, a value of an allowed mismatch, and a minimum support, obtaining supports of similar patterns of a child pattern, each of the similar patterns having a mismatch value with the child pattern that is greater than the value of the allowed mismatch, based on mismatch values of similar patterns of a parent pattern, and determining whether a support of the child pattern fulfills a condition of the minimum support based on the supports of the similar patterns of the child pattern, and a support of the parent pattern.
