background & aims of the study: drinking polluted water can transmit diseases, so potable water treatment is one of the most challenging and complex systems in countries. continuous monitoring for evaluation process in water treatment plant is important. this study aims to investigate performance evaluation of qom water treatment plant to remove turbidity and coliform in 2005 - 2014. materials ...

in this paper, first the available single charting methods, which have been proposed to detect simultaneous shifts in a single process mean and variance, are reviewed. then, by designing proper simulation studies these methods are evaluated in terms of in-control and out-ofcontrol average run length criteria (arl). the results of these simulation experiments show that the ewma and ewms methods ...

Hemodynamic monitoring, a cornerstone in the management of the critically ill patient, is used to identify cardiovascular insufficiency, its probable cause, and response to therapy. Still it is difficult to document the efficacy of monitoring because no device improves outcome unless coupled to a treatment that improves outcome. Several clinical trials have consistently documented that preoptim...

Much of our expectation of the future is based on a linear extrapolation from the present. However history tells us time and again that it’s the nonlinearities that make the big differences in predicting the future. New technologies like smart materials, MEMS, micro adaptive flow control, and nanotechnology all have the potential to have a big influence on the future of aeronautics. A forward-l...
