Abstract: An underwater testing platform assembly includes first and second rails for disposition in part in a body of water, each of the rails having facility for connection to a surface vessel. The rails are disposed vertically, parallel to each other. A cage comprising a network of struts is mounted on the rails. A skid is mounted on, and is movable in, the cage, and can receive and retain an apparatus to be tested. First and second travelers are fixed to the cage and are movably mounted, respectively, on the rails, such that the cage is vertically movable on the rails. Instrumentation is mounted on the cage. A transmission line is connected at a first end to the instrumentation and extends to the surface vessel. A receiver on the surface vessel has a second end of the transmission line connected thereto and receives data signals from the instrumentation.

Abstract: An imitation cheese composition is made with less than 2% protein and/or less than 1% casein protein and comprises a) about 3% to about 30% starch; b) about 0% to about 30% edible lipid material; c) about 20% to about 60% water; d) about 0.5% to about 25% non-starch carbohydrates; and e) about 0.5% to about 5% hydrocolloid stabilizers; and optionally contains up to about 2% cheese flavor and up to about 2% color.

Abstract: A method of acoustic processing for acoustic image classification of an underwater target from a set of known target hypotheses is provided. An acoustic waveform is transmitted into a test volume of water containing the target to be classified. The test volume is divided into test cells such that each test cell contains a portion of the target or scatterer that will scatter the transmitted waveform. Scattering of the transmitted waveform at each test cell is described by a scattering coefficient that is unique for each of the targets in the set of known hypotheses. Accordingly, the scattering coefficient serves as an identifier of the target to be classified. The relationship of the set of scattering coefficients for each of the known target hypotheses is provided by a known covariance matrix. An acoustic receive array receives a portion of the scattered waveform from each of the test cells in the test volume.
