Losail International Circuit grass to stop the sand encroaching on the track. It happens to be somewhat similar to the Bahrain International Circuit in Sakhir. In 2007, Losail added permanent outdoor lighting for night races. At the time, the lighting of the Losail Circuit by Musco Lighting was the largest permanent venue sports lighting project in the world, a distinction that now belongs to another Gulf motorsport venue, Yas Marina Circuit in Abu Dhabi. The first night race in MotoGP history was the Commercialbank Grand Prix of Qatar in March 2008. In February 2009, a GP2 Asia Series nighttime race took place. Best
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
