A system and method in accordance with the present invention reduce the amount of data that is stalled in a source Node B after a serving HS-DSCH cell change in a communication system that includes a serving RNC and at least one Node B. The DFT is completely self contained with on board power supply, control unit, and water tank. The voltage or charge of these test pads may be detected using any suitable sensing device, such as an electron beam, an electro-optical sensor, or an electrode in close proximity to the surface of the pixels andor drivers capacitively coupled to the pixel or driver. In some embodiments, a measure of value N indicates that a given property that is being checked will not be violated within a distance N from an initial state from which the analysis started. The method may also include storing the metallic powder in a rotating storage chamber that is pressurized to a super-atmospheric pressure with a dry cover gas. The metal oxide thin film substrate includes a base substrate, and a metal oxide thin film formed on the base substrate.
