Abstract: A solution is provided that efficiently tracks user paths within a large network. Raw node visit data may be received that indicates which users visited which nodes in the network at which time. This data may then be organized into sessions. Unique pathviews may be calculated for each session of the nodes visit data as well as the frequency of occurrence of each unique path view. This information may then be used to understand how users are progressing through a network.

Abstract: An apparatus for characterizing a library containing an array of samples. The apparatus includes an x-ray beam directed at the library, a chamber housing the library and a beamline for directing the x-ray beam onto the library in the chamber. The chamber may include a translation stage that holds the library and that is programmable to change the position of the library relative to the x-ray beam and a controller that controls the movement of the translation stage to expose an element to the x-ray beam in order to rapidly characterize the element in the library. During the characterization, the x-ray beam diffracts upon impinging the element and a detector detects the diffracted x-ray beam in order to generate characterization data for the element.

Abstract: A method for preparing a library is provided in which the library contains an array of elements and each element contains a different combination of materials. A related apparatus includes an x-ray beam directed at the library, a chamber which houses the library and a beamline for directing the x-ray beam onto the library in the chamber. The chamber may include a translation stage that holds the library and that is programmable to change the position of the library relative to the x-ray beam and a controller that controls the movement of the translation stage to expose an element to the x-ray beam in order to rapidly characterize the element in the library. During the characterization, the x-ray beam scatters off of the element and a detector detects the scattered x-ray beam in order to generate characterization data for the element.
