A time-step insensitive recurrent approach to analyze non-stationary random responses. (Received in the final form October 28, 2008).
Journal Title: Computer Assisted Methods in Engineering and Science - Year 2009, Vol 16, Issue 1
Abstract
The recurrent approach constructed via the stochastic central difference (SCD) is a very fast method for analyzing non-stationary random responses. However, the computational results depend to a great extent upon the discrete time-step size. A new recurrent approach is proposed in this report. It is based on the theory of linear differential equations. Theoretical analysis shows that this algorithm is unconditionally stable for all damped systems. Two examples show that the proposed approach is not sensitive to the time-step.

The analysis of long-term borehole heat exchanger system exploitation
The key issue in designing borehole heat exchangers (BHE) is the long-term performance of the ground source heat pump (GSHP) systems. The performance directly reflects economic profitability and depends on a large number...
Validation of an experimental technique with the physically based global method
Validation of an experimental approach requires that both model and data errors are proved to be within acceptable ranges. In case of destructive testing none of the classic, statistically based methods can be applied fo...
