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 ...

background evaluation of the accuracy and performance of sonography units needs tissue-mimicking phantoms. these phantoms play an important role by simulating soft tissues, obviating the need to experiment on humans or animals. objectives to present a simple sonographic phantom for quality control and training purposes. materials and methods the presented phantom consists of a two-part plexigla...

a simple inexpensive con!nuous quality control method, by means of eight basic blood coun!ng parameters, obtained from automated hematology analyzers, using pa!ent samples, is described. a few samples with low, normal and high values were selected and introduced to the instrument early in the morning as the first count, the results of which are plo#ed on the appropriate chart as dots. the same ...

Formal methods are being applied to the development of software of various applications at Philips Healthcare. In particular, the Analytical Software Design (ASD) method is being used as a formal technology for developing defect-free control software of highly sophisticated X-ray machines. In this paper we analyze the effects of applying ASD in the development of various control software units....

abstract in this paper, a fuzzy pid with new structure is proposed to solve the load frequency control in interconnected power systems. in this study, a new structure and effective of the fuzzy pid-type load frequency control (lfc) is proposed to solve the load frequency control in interconnected power systems. the main objective is to eliminate the deviations in the frequency of different area...
