Round-off error - Wikipedia
WebA general analysis of the condition of the linear least squares problem is given. The influence of rounding errors is studied in detail for a modified version of the Gram-Schmidt orthogonalization to obtain a factorizationA=QR of a givenm×n matrixA, whereR is upper triangular andQ T Q=I. Letx be the vector which minimizes ‖b−Ax‖2 andr=b−Ax. It is … WebPolycrystalline diamond compact (PDC) bits experience a serious wear problem in drilling tight gravel layers. To achieve efficient drilling and prolong the bit service life, a simplified model of a PDC bit with double cutting teeth was established by using finite-element numerical simulation technology, and the rock-breaking process of PDC bit cutting teeth … WebNumerical methods expert with 25 years experience in R&D, Mohammed worked on a wide variety of domains of application (PDE’s numerical analysis, image and signal processing …).
