The present invention provides a U-seam for coupling a panel to an electronics bay. The method includes defining an objective of the R&D activity and determining one or more requirements for fulfilling the objective of the R&D activity. The sub-micrometer scale material and the metallo-organic compound are mixed in a solvent. The exhaust control signal is communicated to the electronic engine controller, which responds by altering engine operation to change some aspect of the engine exhaust. At the same time, roll motions of the driver cabin, with respect to the understructure or the chassis, can be actively prevented. A continuous annular seal is provided between the first and second parts, and a substantially continuous layer of damping fluid is provided between the first and second parts.
