Nonparametric profile monitoring (NPM) is for monitoring over time a functional relationship between a response variable and one or more explanatory variables when the relationship is too complicated to be specified parametrically. It is widely used in industry for the purpose of quality control of a process. Existing NPM approaches require a fundamental assumption that design points within a p...

AN OPTIMIZATION OF ON-LINE MONITORING OF SIMPLELINEAR AND POLYNOMIAL QUALITY FUNCTIONSbyGALAL M. ABDELLADecember 2011Advisor: Dr. Kai YangMajor: Industrial EngineeringDegree: Doctor of PhilosophyThis research aims to introduce a number of contributions for enhancingthe statistical performance of some of Phase II linear and polynomial profilemonitoring tec...

We thank the editor Professor David Steinberg for organizing this stimulating discussion. We are also grateful to all the discussants for their constructive comments about the method proposed in our paper (denoted as QZW hereafter). Profile monitoring is a relatively new research area; but, it has a profound application background (cf., Wang and Tsung 2005, Woodall et al. 2004). Due to the fact...

background and aims:nosocomial infections cause considerable morbidity and mortality and pose high financial burden on healthcare systems. although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. the purpose ...

A foil-based secondary emission monitor (SEM) was developed for beam profile measurements at the Ultra-low energy Storage Ring (USR) that will be installed at the future Facility for Low-energy Antiproton and Ion Research (FLAIR) in Darmstadt, Germany. Simulations of the optimised design of the monitor are presented. Furthermore, its usability for the low energy antiproton (p̄) beam profile moni...

We consider changepoint detection in a process in which the observed points are profiles: large sets of functionally related points (x, y). Few changepoint detection methods have been proposed that don’t rely in some capacity on the assumption that the observational errors are normally distributed. In this paper, a nonparametric distribution-free wavelet method is proposed for monitoring for ch...

Activity patterns and sleep-wake cycles are among the physiological processes that change most prominently as animals age, and are often good indicators of healthspan. In this study, we used the video-based high-resolution behavioral monitoring system (BMS) to monitor the daily activity cycle of tephritid fruit flies Anastrepha ludens over their lifetime. Surprisingly, there was no dramatic cha...

The wheel and rail interaction is the main influence on the dynamic response of a rail vehicle. Any changes in the wheel and rail will change the overall response of the vehicle. The condition monitoring challenge is to interpret these changes into useful condition information. This paper presents the results from initial feasibility studies into model-based condition monitoring at the wheel-ra...

We have developed a simple and relatively inexpensive system to visualize adherent cells in profile while measuring their mechanical properties using microindentation. The setup allows simultaneous control of cell microenvironment by introducing a micropipette for the delivery of soluble factors or other cell types. We validate this technique against atomic force microscopy measurements and, as...
