Yas Island development. Yas Island holds the Yas Marina Circuit, which has hosted the Formula One Etihad Airways Abu Dhabi Grand Prix since 2009. Both business and leisure travelers visit Yas Island. Yas Island was named the world's leading tourism project at the World Travel Awards in November 2009. The Park’s foundation stone was laid on 3 November 2007. The development was completed in a little under three years, opening to the public for the first time on November 2010. Formula Rossa, one of the park's most famous attractions, is the world’s fastest rollercoaster reaching a speed of 240 kph (149 mph).
Circuit rank of any planar graph with the same vertex set, is called the meshedness coefficient. For a connected planar graph with edges and vertices, the meshedness coefficient can be computed by the formula Here, the numerator formula_5 of the formula is the circuit rank of the given graph, and the denominator formula_6 is the largest possible circuit rank of an -vertex planar graph. The meshedness coefficient ranges between 0 for trees and 1 for maximal planar graphs. The circuit rank controls the number of ears in an ear decomposition of a graph, a partition of the edges of the graph into
