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 ...
They come in lengths generally between seven and thirty-three meters. Experimentation with line lengths is common in kiteboarding. 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 ...
The tug kite line is very elastic; when tensed, the line is long; during use for launch, the kite line shortens. Controlling the kite's wing attitudes is up to the pilot who frequently is hung from a short kite line while controlling a triangle control frame or other airframe part or even aerodynamic surface controls. Professional instruction ...
However, the kite is an inflatable rather than a ram-air kite. [citation needed] Additionally, a control pod is used rather than direct tension on multiple kite control lines; only one line runs the full distance from kite to ship, with the bridle lines running from kite to control pod. Power to the pod is provided by cables embedded in the ...
The lift generated by the kite and other flying characteristics are affected by the kite's angle of attack, which is set by the bridle; the arrangement of lines which terminate the main kite lines and attach to a number of points across the kite's surface. Power kites having 4 or 5 lines come in two variants, fixed bridle and depowerable.
Kite fighting has caused horrific injuries and even deaths, and a bill moving through Brazil's Congress is seeking to prohibit the manufacture, sale and use of the razor-sharp lines nationwide ...
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.
