Abstract: A system for measuring structural integrity includes a self-contained rapid modal testing trailer that delivers an impact load to a structure being tested and records data resulting from the impact load, and a data processing software that extracts modal parameters of the structure, such as frequencies and mode shapes. The parameters are used to determine anomalous behavior as well as provide experimental data for finite element model calibration.

Abstract: The invention relates to a system, methods, and computer-readable media for transferring one or more files to a computer in advance of their use by the computer. In accordance with one method of the invention, the computer sends a request for instructions to acquire at least one predetermined file. The request includes information regarding the location of a cache on the computer. The computer receives the instructions to acquire the file, as well as at least one cookie, which includes information regarding the file and the location of the cache. Based on the instructions, the computer obtains the file and stores it in the cache in advance of its use by the computer. If a web page that includes the file is requested, the request for the web page includes the cookie. The computer then receives data that represents that web page and includes a reference to the file stored in the cache at the computer. The reference may be used to open the file stored in the cache.
