A technique for prioritizing portions of compressed multi-resolution medical image data to be processed. The plates include sloped surfaces and are mounted for displacement such that the ratio of the thicknesses of the two plates through which the optical pulses will pass can be varied by displacing the plates so as to shift the carrier-envelope phase in the optical pulses. A support member supports the edge of the vibration member. Atmosphere models include standard day atmosphere models and non-standard day atmosphere models, and wind models include continuous wind turbulence models and discrete wind turbulence models. Embodiments of the method further may comprise allowing the settable composition to set. The continuous conductor provides a low electrical resistance path from a base contact to the intrinsic base.
