With the functionality of most embedded systems based on software (SW), interactions amongst SW modules arise, resulting in error propagation across SW them. During SW development, it would be helpful to have a framework that clearly demonstrates the error propagation and containment capabilities of the di erent SW components. In this paper, we assess the impact of inter-modular error propagati...

Data error is an obstacle to effective application, integration, and sharing of data. Error reduction, although desirable, is not always necessary or feasible. Error measurement is a natural alternative. In this paper, we outline an error propagation calculus which models the propagation of an error representation through queries. A closed set of three error types is defined: attribute value in...

The reliability of file systems depends in part on how well they propagate errors. We develop a static analysis technique, EDP, that analyzes how file systems and storage device drivers propagate error codes. Running our EDP analysis on all file systems and 3 major storage device drivers in Linux 2.6, we find that errors are often incorrectly propagated; 1153 calls (13%) drop an error code with...

Among the many problems in the Self-servo Track Writer (SSTW), the error propagation problem is discussed in this paper. To deal with the error propagation problem, we take two approaches: estimation of the absolute head position and reference correction design using the Position Error Signal (PES) in the previous track. To improve the estimation of absolute position of the head with regard to ...

Data quality in GIS has been widely recognized as one of the most critical issues in GIS applications in recent years. There are numerous effective error models for managing error propagation in the process of data manipulation and analysis. But there is still a lack of error analysis and its propagation in topological operations. In practical applications, data sources, which have different ac...

An increasing number of satellites are currently being launched into orbit to work in the form clusters or constellations. However, initial position is accompanied by random errors, which will propagate during their running. Therefore, precision directly affects space safety, network accuracy, and operating efficiency. Hence, accurate fast error estimation essential improve satellite control. T...

Error(s) in Huffman coded wavelet coefficients of a subband usually propagates till the end of subband. Self-synchronizing Huffman codes are used to limit the propagation of the error, by reestablishing synchronization. After regaining synchronization, the decoder may still not be able to align each symbol with its correct location due to the wrong number of decoded symbols in the error propaga...
