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 bridles on the kite restrict the leading edge and hold it in line with the rest of the kite. In addition, the concave trailing edge enables the kite to be sheeted out further than a traditional C- kite, which is why a Bow kite can be nearly 100% depowered. The inflatable and bow kite designs were invented by Dominique and Bruno Legaignoux. [2]
An optional adjustable tack-line can be eased to allow the tack to lift, enabling the sail to also lift and its shoulders to rotate for deeper downwind angles. Depending on the design and size of the boat, sail and position of the tack, asymmetrical spinnaker sheets may be led to pass between the spinnaker and the headstay or, alternatively ...
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 ...
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 ...
A gear graph, denoted G n, is a graph obtained by inserting an extra vertex between each pair of adjacent vertices on the perimeter of a wheel graph W n. Thus, G n has 2n+1 vertices and 3n edges. [4] Gear graphs are examples of squaregraphs, and play a key role in the forbidden graph characterization of squaregraphs. [5]
