Abstract: An electronic device may measure a user's exercise or other activity and output intuitive information regarding the activity. The electronic device may include a sensor that senses a movement of the electronic device. A processor may determine types of activity states of specified unit times, and determine a specific activity state as a representative activity state of a specified time range based on distribution of the activity states of the specified unit times. The processor may output information corresponding to a determined representative activity state. Short bursts of secondary activity which occur during the specified time range may be omitted in the output information.

Abstract: Methods, apparatuses, systems, and devices are described for determining use of areas of a disk drive. In one method, a score of an area node of the disk drive may be increased each time the area node is accessed during a time interval of a series of time intervals. When each time interval elapses, each existing score of the area nodes (e.g., scores of area nodes that have non-zero scores) may be decreased. Further, after being decreased, each existing score may be saved. In such a manner, a time series analysis of data accesses may be implemented. The increases in score may account for the number of accesses during a given interval, and the decreases in score may account for time passage (e.g., time-weighting the scores). Thus, more frequent accesses and more recent accesses result in higher accumulated scores for the corresponding area nodes.

Abstract: Disclosed is a method of manufacturing a metal matrix composite in which oxide nanoparticles are dispersed. Metal matrix composite powders in which oxide nanoparticles are dispersed are prepared. Gibbs free energy of the oxide nanoparticles is greater than that of an oxide of a metal matrix. A bulk processed material is manufactured from the composite powders through hot forming or a cast material is manufactured by inputting the composite powder into a molten base metal and then rapidly stirring a resultant mixture. The bulk processed material or the cast material is heat-treated so that atoms of the metal matrix and atoms of the oxide nanoparticles mutually diffuse. Oxygen atoms originating from the oxide nanoparticles are diffused and dispersed in the metal matrix.
