Abstract: During an incompressible fluid movement, three consecutive times during the movement of the fluid are called first, second, and third times in time order, calculation is performed with two different types of lattices for the first and third times and for the second time. Momentum and mass density at the first time are temporally developed to the third time in accordance with a conservation law by using an upwind velocity field. A pressure at the second time is determined so that a velocity field derived from momenta at the third time satisfies an incompressibility condition, and the field at the third time is corrected by adding a change in momentum caused by a pressure term using the determined pressure. This prevents pressure vibration and avoids the complexity of advective term calculation.

Abstract: Novel tracked orders (i.e., tracked orders that are not present in “healthy” machinery) are useful for locating bearing anomalies. Accordingly, a method for locating bearing anomalies in machinery is provided that includes receiving vibration measurements acquired from the machinery, analyzing the vibration measurements to identify novel tracked orders indicative of bearing anomalies, and ascertaining the location of a bearing anomaly by relating a novel tracked order thus-identified to one or more further tracked orders. Thus, the novel tracked order does not merely indicate the occurrence of a bearing anomaly, but, in combination with the one or more further tracked orders, allows the bearing anomaly to be traced to a particular position.

Abstract: A method, apparatus and computer instructions for application based tracing and for normalization of processor clocks in a symmetric multiprocessor environment. By deliberately establishing a large skew among processor clocks, it is possible to perform application based tracing by directly using the processors. In addition, the identity, time stamp, and drift information of each processor may be used to create a time library. The time library is used to adjust a measured time to execute a program or software routine. The adjusted time is a normalized time that is statistically more accurate than the measured time alone. The adjusted time is then reported as the time to execute the program or software routine.
