Clearly, a different result is obtained by integrating along a vertical line than along the semicircles shown.
Figure 3 shows an example of a polygonal object whose local freedom angles are shown using dark semicircles.
This is achieved by means of a metal sheet inserted between the two semicircles just in the vertical connecting parts.
The class sat in a semicircle with teachers and helpers playing acoustic instruments familiar to them from the class cupboard.
The "ashes" of the first and the black cloud of the second are marked by identical black spirals and semicircles and by star markings.
She sat on a chair close to and facing the bed, at the focus of the semicircle.
Two concentric semicircles represent 50% and 100% response levels and the length of the bold line indicates the percentage of responses at each location tested.
We recorded birds which appeared within a semicircle with a radius of 25 m from the fixed point.
