This paper proposes a weighted variance method to compute the limits of the X ?? and S charts for skewed distributions. The proposed charts extend the weighted variance X ?? and R charts in by enabling a process from a skewed distribution with moderate and large sample sizes to be monitored efficiently, hence producing more favourable Type-I and Type-II error rates than the charts in. Note that the...
The medical costs for elderly people in Taiwan have increased largely due to the increasing number of aging people in the country. To meet the goals and requirements of the National Health Insurance (NHI), designing and providing a program which would reduce the unnecessary medical services demanded by elderly people is needed. In this research, a conceptual service model of the telecare system applied...
This correspondence is concerned with adaptive digital processing to extract impulse-like signal features from the correlated background noise for detection of intruders with the seismic sensor data. Both the adaptive digital filtering and the adaptive Kalman filtering methods are developed and shown to perform nearly the same for a short data segment. For continued processing of a long duration seismic...
