Krackhardt introduced the graph in 1990 to distinguish different concepts of centrality. It has the property that the vertex with maximum degree (labeled 3 in the figure, with degree 6), the vertex with maximum betweenness centrality (labeled 7), and the two vertices with maximum closeness centrality (labeled 5 and 6) are all different from ...
The lines attach to different controllers: Rings or wrist loops These are commonly found on smaller foils. Two-line bars These are found on LEIs, target kites, and other recreational, and special-application kite systems. [13] [14] They almost always have a wrist leash attached to one of the lines so that the kite will come down if the bar is ...
Spinners and spinsocks can be attached to the flying line for visual effect. There are rotating wind socks which spin like a turbine. On large display kites these tails, spinners and spinsocks can be 50 feet (15 m) long or more. Modern aerobatic kites use two or four lines to allow fine control of the kite's angle to the wind.
quasi-line graph A quasi-line graph or locally co-bipartite graph is a graph in which the open neighborhood of every vertex can be partitioned into two cliques. These graphs are always claw-free and they include as a special case the line graphs. They are used in the structure theory of claw-free graphs. quasi-random graph sequence
The lines attach the rider's control bar to the kite using attachment cords on the kite edges or its bridle. Most power kites use a 3, 4 or 5-line configuration. Most control bars have 4 lines, 2 for most of the propulsive power and 2 for steering and for control of the angle of attack.
It was a macho showdown between opponents wielding unlikely weapons — kites. On this July morning in the impoverished neighborhood, they were using taut, sharp-edged kite lines — known as ...
A set of kite lines. In kiting, a line is the string or thin cord made of cotton, nylon, silk, or wire, which connects the kite to the person operating it or an anchor. Kites have a set of wings, a set of anchors, and a set of lines coupling the wings with the anchors. Kite lines perform various roles: bridle, control, tug, or special duty.
The lines on a C-kite attach to the four corners of the kite. Hybrid kites, together with bow kites and later delta kites are all subtypes of a SLE-kite (Supported Leading Edge), defined by having a bridle which supports the leading edge. C-kites are the preferred kite of wake-style kiteboarders.
