In the present paper, it has been shown that the arising quadratic matrix system polynomial factors can be handled in parallel and each of them can be solved efficiently with a preconditioning method, resulting in very few iterations.
The solving on the coarse grid, performed with a Preconditioned Conjugate Gradient (PCG) solver for this reason, may involve a large number of communications, which reduces dramatically the performances on massively parallel machines.
Therefore, a compressible solver, i.e., Roe scheme developed by P.L. Roe in 1981, must be combined with a preconditioning method that can make the Roe scheme available at low speeds to allow the above situation to be addressed.
A significant axonal regeneration was observed in rats with a preconditioning lesion of sciatic nerve, consistent with previous studies.
We also investigate whether the neuroprotection seen with forced exercise on a treadmill could be replicated with a preconditioning regimen of voluntary exercise.
We hypothesize that the novice runner can adapt more gradually to the external impact forces of running with a preconditioning program prior to the training program and will be less susceptible to RRIs.
"It's only a fellow, a bloke, saying to his workforce that treating your colleagues with respect is a precondition of your employment.
Carrying out the agreement, however, has gone slowly, with Sudan putting a precondition that South Sudan first end its support for rebels inside Sudanese territory, an accusation South Sudan denies.
At the start of Reagan's second term, Kingon advised the White House that the victory had allowed him to pursue policies that would advance only with bipartisan support — a precondition for success, given that Democrats controlled the House.
