Abstract: A sensor data management apparatus according to an embodiment stores pieces of sensor data in data areas provided corresponding to prescribed data units and manages the pieces of sensor data. The pieces of sensor data have been input from a plurality of sensors. The sensor data management apparatus includes a group determining unit and a data storing unit. The group determining unit is configured to analyze the pieces of stored sensor data and determine groups of sensors based on a result of the analysis. The data storing unit is configured to determine a storage location of a newly input piece of sensor data to store pieces of sensor data from sensors belonging to the same one of the groups in the same one of the data areas, and store the piece of sensor data at the storage location.

Abstract: According to an embodiment, a structured document management device includes a query data receiving unit; a structural condition dividing unit; a structural condition rewriting unit; and a query execution unit. The query data receiving unit is configured to receive query data for searching a structured document. The structural condition dividing unit is configured to divide the query data into elements including a structural condition. The structural condition rewriting unit is configured to rewrite the structural condition into a rewritten query when a type of the structural condition is other than a descendant structural condition. The rewritten query is predetermined to include a joining process with a descendant structural condition so as not to affect structural conditions appearing before and after the structural condition. The query execution unit is configured to output a search result in response to query data that includes the structural condition and the rewritten query.

Abstract: According to an embodiment, a structured document management device includes a parser; a constraint acquiring unit; and a parse tree rewriting unit. The structured document receiving unit is configured to receive an input of a structured document having a layered logical structure. The parser is configured to parse the syntax of received query data to acquire a parse tree in which the query data is decomposed so as to meet a static single assignment form which is defined such that each variable is assigned exactly once. The constraint acquiring unit is configured to acquire a hierarchical condition that the variables of the parse tree need to meet and constraints that include conditions for values of the respective variables. The parse tree rewriting unit is configured to rewrite the query data in such a form that the structured document is refinable by the constraints.

Abstract: An image generation system includes a captured image acquisition section that acquires a captured image captured by an imaging section, a depth information acquisition section that acquires depth information about a photographic object observed within the captured image, an object processing section that performs a process that determines a positional relationship between the photographic object and a virtual object in a depth direction based on the acquired depth information, and synthesizes the virtual object with the captured image, and an image generation section that generates an image in which the virtual object is synthesized with the captured image.

Abstract: A memory controller controls a semiconductor storage device including nonvolatile memory cells. The controller includes a generating circuit, and a selection circuit. The generating circuit generates first data based on a second data. The selection circuit retains a cumulative value whose each digit is a cumulative result in each bit of data which is already written in the memory cells. The selection circuit selects one of the first data. A selected first data has a better average of digits in a sum of each bit of the selected first data and each digit of the cumulative value than an unselected first data. The selection circuit retains the sum concerning the selected first data as the new cumulative value.

Abstract: The objective of the present invention is to provide a game machine and information storage medium that make it possible to encourage players who have selected multi-player mode to continue playing. The maximum number of game stages that can be cleared by players in multi-player mode is set to be greater than the maximum number of game stages that can be cleared by a player in single-player mode. In single-player mode, the game is over at the point at which each course is cleared. In multi-player mode, a continuation privilege in the next course (a course that is more difficult) is granted when the current course is cleared. The privilege to continue playing the next course is granted to the player with the higher score, and is also given at a certain probability to the player with the lower score.
