Control charts are themost extensively used technique to detect the presence of special cause variations in processes. They can be classified intomemory andmemoryless control charts. Cumulative sum and exponentially weightedmoving average control charts are memory-type control charts as their control structures are developed in such a way that the past information is not ignored as it is done i...

In 2010, the EWMA Patient Outcome Group (POG) published recommendations to improve the quality of evidence in wound management. (1) As a companion piece of work, the EWMA POG has worked to provide a series of user-friendly documents to assist those new to (or inexperienced in) research, in starting on the path to plan, conduct, interpret and disseminate findings from an investigation that will ...

The performance of an X-bar chart is usually studied under the assumption that the process standard deviation is well estimated and does not change. This is, of course, not always the case in practice and X-bar charts are not robust against errors in estimating the process standard deviation or changing standard deviation. In this paper, the use of an exponentially weighted moving average (EWMA...

Diagnostic laboratories are increasingly required to meet stringent quality standards, and validated assays are needed to achieve formal accreditation. Validation of test methods is often considered to be finalised when the assay parameters and characteristics have been established. However, like any process, diagnostic assays are subject to random variation resulting in shifts in the mean test...

The environments of WSN frequently disturb the link quality. Link quality not only affects the reliability of data transmission in the network, but also determines the performance of related Upper-layer network protocol. Therefore, link quality evaluation becomes a considering question. The link quality evaluation methods include data package delivery rate and LQI(Link Quality Index). Practical...

Intrusion detection systems typically create large amounts of alerts, processing of which is a time consuming task for the user. This paper describes an application of exponentially weighted moving average (EWMA) control charts used to help the operator in alert processing. Depending on his objectives, some alerts are individually insignificant, but when aggregated they can provide important in...

Quick detection of an assignable cause is necessary for process accuracy with respect to the specifications. The aim this study monitor time and magnitude processes based on unit-interval data. To end, maximum exponentially weighted moving average (Max-EWMA) control chart simultaneous monitoring event proposed. be precise, beta unit gamma distributions are considered develop Max-EWMA chart. cha...

Many extensions and modifications have been made to standard process monitoring methods such as the exponentially weighted moving average (EWMA) chart cumulative sum (CUSUM) chart. In addition, new schemes proposed based on alternative weighting of past data, usually put greater emphasis data less weight current recent data. other cases, output one method, EWMA statistic, is used input another ...

NetFPGA is a hardware board that it is becoming increasingly popular in various research areas. It is a hardware customizable router and it can be used to study, implement and test new protocols and techniques directly in hardware. It allows researchers to experience a more real experiment environment. In this paper we present a work about the design and development of four new modules built on...
