A Block Orthogonalization Procedure with Constant Synchronization Requirements
We propose an alternative orthonormalization method that computes the orthonor-mal basis from the right singular vectors of a matrix. Its advantage are: a) all operations are matrix-matrix multiplications and thus cache-eecient, b) only one synchronization point is required in parallel implementations, c) could be more stable than Gram-Schmidt. In addition, we consider the problem of incrementa...
متن کاملA new orthogonalization procedure with an extremal property
Various methods of constructing an orthonomal set out of a given set of linearly independent vectors are discussed. Particular attention is paid to the Gram-Schmidt and the Schweinler-Wigner orthogonalization procedures. A new orthogonalization procedure which, like the SchweinlerWigner procedure, is democratic and is endowed with an extremal property is suggested. PACS No: 02.10.Sp, 31.15.+q e...
متن کاملEpidural block procedure pitfalls
Objectives: To present a number of cases in which pitfalls may occur during the performance of epidural block, so that they may be prevented and corrected during the procedure. Materials and methods: A retrospective analysis was performed in 118 patients who suffered from lumbar pain, radicular pain or both and who underwent CT-guided minimally invasive anti-inflammatory analgesic treatment by ...
متن کاملRequirements for Secure Clock Synchronization
This paper establishes a fundamental theory of secure clock synchronization. Accurate clock synchronization is the backbone of systems managing power distribution, financial transactions, telecommunication operations, database services, etc. Some clock synchronization (time transfer) systems, such as the Global Navigation Satellite Systems (GNSS), are based on one-way communication from a maste...
متن کاملA Setting for Generalized Orthogonalization
Let H be a complex Hilbert space. We study the geometry of the space of pairs (A,E), for A a (semidefinite bounded linear) positive operator on H and E a (bounded linear) projection on H such that AE = E∗A.
