The operating characteristic (OC) function of the proposed sampling system is developed based on the exact sampling distribution. The plan parameters under various settings are determined by solving two non-linear equations simultaneously, which satisfy the required quality levels and allowable risks ...
This would result in: (8)uh(x)=∑i=1nFFDNiM(x)uiFFD,where uiFFD would be equivalent pressure values at the spline box control points. Such a choice would be similar to the common practice in fictitious domain methods, where the conforming quadrature rule, usually built using octree meshes...
The main parameters for the modular bit model, along with their respective values, are provided in Table 2. Table 2. Main parameters of the modular bit model. The velocity of the drilling fluids flowing upward along the borehole and the pressure loss after drilling fluids have flowed through...
