A Practical Implementation of the Random Ball Test
نویسنده
چکیده
Although the idea must have been around for years the use of a ball for the calibration of interferometer transmissions spheres was, to our knowledge first reported in 1999. The ball used at the time was made of black (neutral density filter) glass and worked fine for a demonstration of the principle but was not really practical because of its relative softness of the glass and susceptibility to damage in everyday use.

Background & Aim: Randomized clinical trials (RCTs) are studies which are able to provide the most valid evidence to compare various interventions in health research. Biases can affect the quality of research and ultimately make the results of a study invalid. One of the most important biases is selection bias. The best way to reduce selection bias is the use of random allocation. The aim of th...

متن کاملImplementation of D3Q19 Lattice Boltzmann Method with a Curved Wall Boundary Condition for Simulation of Practical Flow Problems
In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...
