Disclosed is a display apparatus and a control method thereof. The display apparatus includes a display configured to display an image thereon; a storage configured to store a plurality of files therein to display the image; and a processor configured to: generate a first integrity check value of a first file based on at least one second file corresponding to a request for execution of the first file from an application, and identify whether to execute the first file by identifying whether the first integrity check value generated as above is consistent with a second integrity check value of the first file that has been generated based on the at least one second file before the request for execution of the first file was made.

Display device and control method therefor

An apparatus and method of segmenting sensor data are provided. The apparatus includes a sensor, a first segmentation unit, a continuity evaluation unit, a second segmentation unit, and a segmentation determination unit. The sensor collects sensor data for a process of the semiconductor manufacturing facility. The first segmentation unit extracts a variation point of the sensor data to perform an abnormal difference (AD) segmentation on the sensor data based on the at least one variation point. The continuity evaluation unit evaluates a continuity ratio of the sensor data. The second segmentation unit performs a free-knot spline (FS) segmentation on the sensor data when the continuity ratio exceeds a reference ratio. The segmentation determination unit compares the AD segmentation result with the FS segmentation result and to select one of the results on the comparison result.
