Abstract: According to one embodiment, an analysis apparatus includes an acquisition unit and a processor. The acquisition unit acquires first information with a first time length between a first time and a second time. The first information is based on motion of an object person. The processor extracts multiple similarity points from the first information. The multiple similarity points are similar to each other in the first information. The processor calculates a time interval between the similarity points.

Abstract: A display system includes a processing device. The processing device is operable for, upon receiving a sentence inputted by a user, extracting a keyword from the sentence, and generating a chart related to the keyword from prescribed data and displaying the chart on a first screen.

Abstract: According to one embodiment, a model generation system includes a base model generator, a similarity calculator, a modified model generator, and a generalization ability calculator. The base model generator generates a base model of a relationship between an input variable group and an output variable. The input variable group includes selected input variables selected from input variables. The similarity calculator calculates each similarity between the selected input variables and unselected input variables. The unselected input variables is included in the input variables. The modified model generator interchanges at least a portion of the plurality of selected input variables with at least a portion of the plurality of unselected input variables to generate another input variable group. The modified model generator generates a modified model of a relationship between the output variable and the other input variable group.

Abstract: A heat exchanger such as used as an inter cooler for cooling an intake air of an internal combustion engine has an inner fin which is provided within a tube through which heat transfer medium such as an intake air flows. The inner fin has a plurality pairs of a first vertical wall portion and a second vertical wall portions, a first horizontal wall portion connecting an upper end of the first vertical wall portion to an upper end of the second vertical wall portion, and a second horizontal wall portion connecting a lower end of the first vertical wall portion to a lower end of the second vertical wall portion. The inner fin further has a plurality of slits formed from the vertical wall portion side of the first horizontal wall portion via entire length of the vertical wall portion until the vertical wall portion side of the second horizontal wall portion. The fin pitch P, the length L of vertical wall portion between adjacent pair of the slits, and the width S of the slit are as follows.1.6 mm.ltoreq.P.
