Abstract: An example method for analyzing big data in a network environment is provided and includes extracting a data set from big data stored in a network environment, detecting a pattern in the data set, and enabling labels based on the pattern, where each label indicates a specific condition associated with the big data, and the labels are searched to answer a query regarding the big data. In specific embodiments, detecting the pattern includes capturing gradients between each consecutive adjacent data points in the data set, aggregating the gradients into a gradient data set, dividing the gradient data set into windows, calculating a statistical parameter of interest for each window, aggregating the statistical parameters into a derived data set, and repeating the dividing, the calculating and the aggregating on derived data sets over windows of successively larger sizes until a pattern is detected.

Abstract: A device for testing the adhesion of a coating to a substrate and a method of using the device are disclosed. The device is adapted to substantially replicate and consistently conduct the adhesion test procedure described in ASTM standards D3359 and F1842. The device includes a support with a source of a pressure sensitive adhesive tape rotatably mounted to the support. A tape dispenser and means to cause the tape to contact a test surface are mounted to the support. Means to remove the tape from the test surface is provided that includes a take-up spool adapted to receive the tape removed from the test surface.
