Abstract This paper presents the construction of RLL-ECCs (run length limited error control codes) from three selected ECCs specified by Consultative Committee for Space Data Systems (CCSDS) optical communications. The obtained present a practical alternative to CCSDS codes with pseudo-randomizers. Their advantage is that maximal run lengths equal symbols in their codeword sequences are guarant...

The high complexity of modern software, and our pervasive reliance on that software, has made the problems of software reliability increasingly important. Yet despite advances in software engineering practice, pre-release testing, and automated analysis, reports of highprofile production failures are still common. This dissertation proposes several run-time techniques to analyze and alleviate s...

Cumulative sum (CUSUM) and exponentially weighted moving average (EWMA) control charts are commonly used to detect small changes in the parameters of production processes. Recently, a new control structure was introduced, named as mixed EWMA–CUSUM control chart, which combined both charts. The current study provides a detailed comparison of these three types of control charts when the process p...

Given a sequence of letters generated independently from a finite alphabet, we consider the case when more than one, but not all, letters are generated with the highest probability. The length of the longest run of any of these letters is shown to be one greater than the length of the longest run in a particular state of an associated Markov chain. Using results of Foulser and Karlin (19...
