An apparatus for installing means to supply cold water from depth to a floating vessel comprises a template having a plurality of receptacles for receiving a plurality of vertically-oriented Cold Water Pipes. Compliant members are coupled to the proof mass and enable the proof mass to move parallel to the surface of the substrate in a sense direction. The fixed-unit supports the movable-unit so as to be movable on said plane, and has a hall element for detecting a position of the movable-unit on the plane. An input signal is Fourier-expanded, and a frequency-domain output spectrum is obtained from the transfer function and the Fourier-expanded input signal. A social networking system may also infer an affiliation for a user based on the user’s interaction with a page, application, or entity where other users who interacted with the same page, application, or entity have the same affiliation. The paper can be formulated such that it is useful as an energy storage material andor a current collector.
