I don't see an easy way to create the original shape using an analytic method. You'd need to form a grid over the top of the knob to form the polyhedral face of the top, and that seems pretty difficult to do.

What I mean by absolute phase is that a 1 is always 180 degrees and a zero always 0 degrees. In your example this would imply that the two ones in a row would result in two seconds of 180 degree phase without a flip after the first 1. The document is confusing, but the best I can do with its language is to conclude they are talking about absolute phase. Normally when one talks about baseband waveforms one is referring to absolute I and Q components relative to an unchanging carrier phase, not relative I and Q with respect to the last bit phase. So I take their language to mean a zero is 0 degrees and a 1 180 degrees relative to an unchanging carrier. Differential encoding is the opposite, a 1 is always the opposite phase from the last bit, a zero always the same phase as the last bit (or sometimes the inverse where a zero is the transition and a one is not). > Is there a way to sense from the document that there is a bias towards 0 > lets say. Differential encoding tends to have little "DC" component or bias toward either one or zero or one phase or the other, absolute encoding does if the data it encodes does. -- "An empty zombie mind with a forlorn barely readable weatherbeaten 'For Rent' sign still vainly flapping outside on the weed encrusted pole - in celebration of what could have been, but wasn't and is not to be now either."

For a person with trailerable mobility, the answer is easy: The northern part!

On the marsh all the usual suspects were present, including our solo Trumpeter Swan friend.

Not what you want to see on a bird of such a declining species. I vaguely remember reading something over the past year or two about an increasing number of shorebirds with apparent tumors.
