High Accuracy Measurement of Aperture Area Relative to a Standard Known Aperture
Precise knowledge of the area of apertures used in high precision radiometry is extremely important. A method is presented here for the determination of the area of round and irregularly shaped apertures by comparison to a standard aperture which has been measured by other means to high accuracy. The method presented here is quick and has no physical contact with the fragile edge of the apertur...
متن کاملDouble Aperture Camera for High Resolution Measurement
In the domain of machine vision, the measurement of length is done using cameras where the accuracy is directly proportional to the resolution of the camera and inversely to the size of the object. Since most of the pixels are wasted imaging the entire body as opposed to just imaging the edges in a conventional system, a double aperture system is constructed to focus on the edges to measure at ...
متن کاملSatiated relative permeability of variable-aperture fractures.
Experimental studies of capillary-dominated displacements in variable-aperture fractures have demonstrated the occurrence of a satiated state at the end of invasion, where significant entrapment of the displaced phase occurs. The structure of this entrapped phase controls the behavior of flow and transport processes in the flowing phase. Recent studies have shown that the areal saturation of th...
متن کاملImplicit standard Jacobi gives high relative accuracy
We prove that the Jacobi algorithm applied implicitly on a decomposition A = XDXT of the symmetric matrix A, where D is diagonal, and X is well conditioned, computes all eigenvalues of A to high relative accuracy. The relative error in every eigenvalue is bounded by O(εκ(X)), where ε is the machine precision and κ(X) ≡ ‖X‖2 · ‖X−1‖2 is the spectral condition number of X . The eigenvectors are a...
