The present invention provides an improved TMX. The video encoding system may also include a rate controller to select coding parameters of each portion of the input signal, the rate controller estimating delay of delivery of coded video data by a delivery network according to a leaky bucket modeling process and selecting coding parameters of a portion to be coded based at least in part on the estimated delay. A valley is formed between one side portions of the pair of convex surfaces. Using this process, turbomachines may be manufactured with rotating elements that have outer diameters of less than four inches in size, andor blading heights of less than 0.
