To calculate the VaR for a single asset, we would calculate the standard deviation of its returns, using either its historical volatility or implied volatility. If a 95% confidence level is required, meaning we wish to have 5% of the observations in the left-hand tail of the normal distribut...

Friction drag, pressure drag and parasitic drag can each be expressed with dimensionless parameters. These quantities are also known asdrag coefficients. The meaning of these coefficients is quite analogous to other dimensionless similarity parameters such asReynolds number,Prandtl number,Nusselt number,Sch...
1, the essence of the balance coefficient In order to discuss the essence of the balance coefficient, we must start with the principle of the traction elevator. A vertical lift is a lifting device for vertical and downward movements of heavy objects. From the angle of mechanics, to make a ...
The objective of this study is to develop a genetic algorithm that uses the IGP parameterization to increase the lift coefficient (CL) of three airfoils to be used on wings of unmanned aerial vehicles (UAVs). The geometry of three baseline airfoils was modified by developing a genetic algorithm...
