Krylov subspace iteration
In the simulation of continuous events, such as the ow of a uid through a pipe, or the ow of air around an aircraft, one usually imposes a grid over the area of interest and one restricts oneself to the computation of relevant parameters, for instance the pressure or the velocity of the ow or the temperature, in the gridpoints. Physical laws lead to approximate relations between these parameter...
متن کاملKrylov subspace estimation
Computing the linear least-squares estimate of a high-dimensional random quantity given noisy data requires solving a large system of linear equations. In many situations, one can solve this system e ciently using a Krylov subspace method, such as the conjugate gradient (CG) algorithm. Computing the estimation error variances is a more intricate task. It is di cult because the error variances a...
متن کاملRelaxed Krylov subspace approximation
Recent computational and theoretical studies have shown that the matrix-vector product occurring at each step of a Krylov subspace method can be relaxed as the iterations proceed, i.e., it can be computed in a less exact manner, without degradation of the overall performance. In the present paper a general operator treatment of this phenomenon is provided and a new result further explaining its...
متن کاملFundamental concepts of radiopharmaceuticals quality controls
Quality control (QC) procedures should always be performed following radiopharmaceutical preparation and prior to patient administration. The main aim of QC is to ensure optimal radiopharmaceutical product properties except for some short half-life tracers such as some positron emission tomography (PET) imaging probs. by dispensing a radiopharmaceutical of the highest quality the risk of having...
