On Computing Average Common Substring Over Run Length Encoded Sequences [PDF]
Fundamenta Informaticae, 2018 The Average Common Substring (ACS) is a popular alignment-free distance measure for phylogeny reconstruction. The ACS of a sequence X[1, x] w.r.t. another sequence Y[1, y] is ACS(X, Y) = 1 x ∑ i=1 x max j lcp(X[i, x], Y[j, y]) The lcp(·, ·) of two input sequences is the length of their longest common prefix.

The Expected Average Run Length of the EWMA Median Chart with Estimated Process Parameters
Austrian Journal of Statistics, 2020 The performance of a control chart is commonly investigated based on the assumption of known process parameters. Nevertheless, in most manufacturing and service applications, the process parameters are usually unknown to practitioners.

A New Control Chart for Monitoring Reliability Using Sudden Death Testing Under Weibull Distribution
IEEE Access, 2017 In this paper, a new control chart using sudden death testing is designed by assuming that the lifetime/failure time of the product follows the Weibull distribution. The structure of the proposed chart is presented.

A Comparison of Shewhart-Type Time-Between-Events Control Charts Based on the Renewal Process
IEEE Access, 2020 To study the high quality processes, time-between-events (TBE) control charts have several advantages over the ordinary control charts. However, the existing TBE charts are based on the exponential distribution, which limit the application of these ...

A Variable Control Chart under the Truncated Life Test for a Weibull Distribution
Technologies, 2018 In this manuscript, a variable control chart under the time truncated life test for the Weibull distribution is presented. The procedure of the proposed control chart is given and its run length properties are derived for the shifted process. The control

The np Chart with Guaranteed In‐control Average Run Lengths [PDF]
Quality and Reliability Engineering International, 2016 We evaluate the in‐control performance of the np‐control chart with estimated parameter conditional on the Phase I sample. We then apply the bootstrap method to adjust the control chart limits to guarantee the desired in‐control average run length (ARL0) value in the monitoring stage.

A Multivariate Control Chart for Monitoring Several Exponential Quality Characteristics Using EWMA
IEEE Access, 2018 In this paper, we propose a new multivariate control chart for monitoring several exponential distributed characteristics. We transform each exponential variable into the one following an approximately normal distribution.

Monitoring Reliability for Three-Parameter Frechet Distribution Using Control Charts
IEEE Access, 2020 Control Charts for attributes have been widely adopted for examining the fraction non-conforming or non-conformities in a process. However, Shewhart control charts may face some practical problems when the process fraction of non-conformities is very low.
