In this paper we introduce error-control techniques for improving the error-rate performance that is delivered to an application in situations where the inherent error rate of a digital transmission system is unacceptable. The acceptability of a given level of bit error rate depends on the particular application. For examples, certain types of digital speech transmission are tolerant to fairly ...

An Ecient P Ath Delay F Ault Coverage Estimator

|We propose a linear complexity method to estimate robust path delay fault coverage in digital circuits. We adopt a path counting scheme for a true-value simulator that uses ags for each signal line. These ags determine the new path delay faults detected by the simulated vector pair. Experimental results are presented to show the e ectiveness of the method in estimating path delay fault coverage.

The concept of model transformations is of increasing importance in different areas of Computer Science, but up to now, there is a lack of common understanding concerning the mathematical and practical point of view. In this paper, we discuss some of the different aspects. Especially interesting is the new proposal of the POPL’07 keynote speaker Don Batory claiming that model transformations sh...

Fault diagnosis method based on the moment characteristic of system pressure data is presented in this paper. Using AMESim simulation technology, three typical faults of the brake system are studied. After the moment and the percentile characteristics of the pressure curve of the hydraulic system are extracted and used as characteristic parameter, fault information is diagnosed effectively usin...
