This talk presents results of a comparitive study of iterative algorithms like minimal residue (MR) and conjugate gradient (CG, BiCGγ5, and BiCGstab) used for inverting the Dirac matrix M . The tests were done on the Connection Machine CM-5 using 32 × 64 lattices. The fermion action used is of Wilson type, both with and without the clover term. The overall conclusion is that preconditioned over...

introduction: coronary artery disease (cad) is the most common type of heart disease, with a mortality rate of 385,000 person per year in the united states. there are two main methods for cad treatments: angioplasty and bypass surgery. coronary artery bypass grafting (cabg) is one of the greatest surgical operations of the 20th century and it is presented as most effective and long-term therapi...

In this paper it is attempted to predict the off-design performance of a jet engine. After a review of the governing equations, the off-design performance is investigated by two methods. In the first method, the component characteristic curves of the Gas Turbines are used. In the second method some design point parameters and the reference state conditions are employed. The results obtained by ...
