BACKGROUND Retinopathy of prematurity (ROP) is a sight-threatening disease affecting extremely preterm infants. The introduction of new ROP screening surveillance systems, with higher sensitivity and specificity than established ROP screening guidelines, has the potential to reduce the number of stressful eye examinations in these infants. OBJECTIVES To improve the specificity of the WINROP (...

Statistical control charts are useful tools in monitoring the state of a manufacturing process. Control charts are used to plot process data and compare it to the limits set for the process. Points plotting outside these limits indicate an out-of-control condition. Standard control charting procedures, however, are limited in that they cannot take into account the case when data is of a fuzzy n...

A more practical design of X-chart has been proposed which recognizes that the process mean, in the majority of industrial operations, is a random variable, and uses the necessary information on the production rate and specification limits and the ratio of costs of false alarm and producing defectives. A methodology has been proposed to see whether incorporation of warning limits is effective f...

The acoustic environment of a typical Neonatal Intensive Care Unit (NICU) is highly diverse and may contain a large number of sounds coming from numerous sources, such as alarm sounds generated by di erent biomedical equipment, noisy mechanical ventilation, telephone ring sound and people conversations. Various acoustic events are usually taking place simultaneously in a NICU and the maximum re...

The lack of effective data integration and knowledge representation in patient monitoring limits its utility to clinicians. Intelligent alarm algorithms that use artificial intelligence techniques have the potential to reduce false alarm rates and to improve data integration and knowledge representation. Crucial to the development of such algorithms is a well-annotated data set. In previous stu...

BACKGROUND Monitoring clinical interventions is an increasing requirement in current clinical practice. The standard CUSUM (cumulative sum) charts are used for this purpose. However, they are difficult to use in terms of identifying the point at which outcomes begin to be outside recommended limits. OBJECTIVE To assess the Bernoulli CUSUM chart that permits not only a 100% inspection rate, bu...

We discuss a Bayesian approach to the analysis of radial velocities in planet searches. We use a combination of exact and approximate analytic and numerical techniques to efficiently evaluate χ for multiple values of orbital parameters, and to carry out the marginalization integrals for a single planet including the possibility of a long term trend. The result is a robust algorithm that is rapi...

We provide comments on a research paper proposing control chart to monitor the scale parameter of Rayleigh distribution. Our primary focus is improving its average run length profile. determine limits such that, average, one can detect any change in this more quickly than trigger false alarm.

This article presents a control chart for time series data, based on the one-stepahead forecast errors of the Holt-Winters forecasting method. We use robust techniques to prevent that outliers affect the estimation of the control limits of the chart. Moreover, robustness is important to maintain the reliability of the control chart after the occurrence of alarm observations. The properties of t...
