![]() ![]() For an arch of uniform density and thickness, supporting only its own weight, the catenary is the ideal curve. What makes the catenary arch important is its ability to withstand the weight. The catenary is the locus of the focus of a parabola rolling along a straight line. Catenary Curve: The catenary is the shape of a perfectly flexible chain suspended by its ends and acted on by gravity.It became the standard map projection for nautical purposes because of its ability to represent lines of constant course as straight segments that conserve the angles with the meridians. Mercator’s Projection: The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569.The Benz network is a non-blocking network and it is generated by joining two butterfly networks back to back, in such a manner that data flows forward through one and in reverse through the other. The butterfly network is modified in Benz network. ![]() Butterfly network in Computer Algorithm: A butterfly network is a blocking network and it does not allow an arbitrary connection of N inputs to N outputs without conflict.It used only physical & chemical makeup of the fuel and the conditions in which it is expected to burn. The model didn’t use any prior knowledge of a fuel’s burning characteristic. Predicting fire spread in wildlife fields: This mathematical model of fire presented in this paper offers for the first time a method for making the quantitative evaluation of both rates of spread and fire intensity in fuels that qualify for the assumptions made on the model.
