A road crossing aid for pedestrians, comprises a lightweight reflecting section in the form of a hand. The outer edge strip (5) and/or arrow (4) consist of a reflecting material, eg a PE foam, a hard foam or rubber.TACKE, GABRIELE...
We explore the maximum total number of edge crossings and the maximum geometric thickness of the Euclidean minimum-weight (k, )-tight graph on a planar point set P. In this paper, we show that (10/7-ε)|P| and (11/6-ε)|P| are lower bounds for the maximum total number of edge ...
According to the improvement each wall has a shoulder and an projecting tab at its leading edge, the tabs being glued together and being glued in a longitudinal slot in the edging strip. At the point where the aerofoil section is joined to another part of the plane a smoothing piece is ...
