Usually, in monitoring a proportion p < /em>, the binary observations are considered independent; however, in many real cases, there is a continuous stream of autocorrelated binary observations in which a two-state Markov chain model is applied with first-order dependence. On the other hand, the Bernoulli CUSUM control chart which is not robust to autocorrelation can be applied two-sided co...

This paper analyses and evaluates the properties of a CUSUM chart designed for monitoring the process mean in short production runs. Several statistical measures of performance that are appropriate when the process operates for a finite-time horizon are proposed. The methodology developed in this paper can be used to evaluate the performance of the CUSUM scheme for any given set of chart parame...

Figure 2 Using the indices of haemoglobin (IHb) colour chart function provided by the Olympus EVIS LUCERA system, the reference IHb values are displayed in yellow, with areas higher than the reference value (hypervascular) displayed in “warm” colours (i. e., orange±red) and hypoperfused areas displayed in “cool” col− ours (blue±grey). IHb charting of the lesion shows a clear vascular map. The l...

OBJECTIVE Compare the performance of Lea Symbols and Sheridan Gardiner charts against the standard test chart used to determine reduced VA during vision screening among pre-schoolers. MATERIAL AND METHOD Seven hundred seventy five pre-school participated where 389 subjects were boys and 386 subjects were girls were tested using the Lea Symbols chart and the Sheridan Gardiner chart. The mean a...

This paper presents a framework for the definition of monotonic repair rules on chart items and Lexicalized Tree Grammars. We exploit island representations and a new level of granularity for the linearization of a tree called c o n n e c t e d routes. It allows to take into account the topology of the tree in order to trigger additional rules. These local rules cover ellipsis and common extra-...

BACKGROUND Different visual acuity chart can be targeted to evaluate the visual function of patients with different eye diseases. We conducted a comparative analysis of the digital logarithm of the minimum angle of resolution (LogMAR) vision chart and the standard logarithmic vision chart for the measurement of visual acuity after retinal detachment surgery. METHODS We used the digital LogMAR...

OBJECTIVES To evaluate the feasibility, applicability and the value of customised symphysio fundal height (SFH) charts developed for women of Indian origin in the United Kingdom (UK: CSFH - In chart) and women of African origin in the UK (CSFH - Af chart) in detecting fetal growth restriction and predicting low birth weight (LBW) of the neonate in a Lankan population, and to compare these resul...

The attribute Conforming Run Length (CRL) control chart has attracted increasing research interests in Statistical Process Control (SPC). It decides the process status based on the interval or distance between two nonconforming units. This article proposes a Generalized CRL chart (namely GCRL chart) for monitoring the mean of a measurable quality characteristic x under 100% inspection. To run a...

As a part of ongoing research to look at the pragmatic value of the stages of growth concept to map the progression of e-business maturity, this paper describes some of the empirical findings of a qualitative study into the progression and maturity of e-business in small and medium enterprises in Australia. In particular, the paper discusses the progression of ebusiness initiatives in three dif...
