Abstract: A method and an apparatus for processing a query are disclosed. When the query is input, in a case in which partitions are present in a data table, a partition corresponding to the input query is selected, and in a case in which one or more partition column sets are present in the selected partition, one or more partition column sets corresponding to the input query are selected, and the query is processed for the selected partition column sets.

Abstract: Methods and apparatus for avoiding or exploiting air drag on an aerial vehicle are disclosed. In embodiments, the methods and apparatus may be implemented in a controller and used to increase the energy efficiency of an aerial vehicle. In the embodiments, at least one parameter associated with a force on an aerial vehicle is determined. A yaw setting for the aerial vehicle is then determined that exploits or avoids air drag on the aerial vehicle for energy efficiency. The yaw setting may be referenced to a yaw based on directionality in the shape of the aerial vehicle. In other embodiments, a drag associated with a force on an aerial vehicle is determined. It is then determined if there is a selected component in the drag based on a desired maneuver of the aerial vehicle. A yaw setting is then determined based on whether the selected component is in the drag.

Abstract: A system of recollection using the search of records of the past, includes a database (DB) device storing records of individual's past events and things, a search computing device for making a search request in response to a user's request, a server computing device for searching the DB device in response to the search request to extract result data, and a presentation computing device for integrating and presenting the result data extracted from the server computing device by using multisensory elements.

Abstract: Provided is a method and apparatus for detecting multi moving objects in high resolution image sequences and performs moving objects on a screen using a general image collecting apparatus. The present invention provides a method of effectively removing the background of moving objects like motion of a leaf or reflection of a wave in an outdoor environment using a statistical method and uses a GPU installed in a general computer to process high resolution image sequences at high speed.

Abstract: An apparatus for generating location information based on a web map includes a location information extracting unit that extracts the location information on the web map corresponding to each spot selected depending on movement of a pointer for searching the location information of the web map on the web map, which is received from a web map information storage server storing the web map and a location data generating unit that generates location data by using the location information extracted by the location information extracting unit. According to above, a system for generating location information based on a web map can provide an environment where various located-based services can be developed without an actual physical device in order to develop a service utilizing the location information.

Abstract: Provided is an apparatus for tracking an object, including: a dynamic area extracting unit that extracts an object to be tracked from an image frame collected through an image collecting apparatus; an object modeling unit that models the object to be tracked extracted through the dynamic area extracting unit to calculate the color distribution of the object to be tracked; and an object tracking unit that calculates the color distribution of a next image frame collected through the image collecting apparatus, after calculating the color distribution of the object to be tracked, and calculates a posterior probability that each pixel belongs to the object to be tracked in the next image frame based on the calculated color distribution of the next image frame and the color distribution of the object to be tracked to track the object to be tracked.

Abstract: A method for file deletion and recovery against system failures in a database management system comprising steps of deleting files listed in a pending action list during a transaction commit process, writing a non-atomic file deletion as an atomic operation into a log and recovering uncompleted file deletion during restart recovery by using the log is disclosed. When system failures occur during file deletion in a database management system, resources of which releasing is interrupted by failures are released perfectly through recovery step, so it is advantageous in that coherency of data is maintained and efficiency of storage device arises.
