In this paper a multivariate quality control procedure is offered in which several correlated stages are present in production systems and in each stage there are several correlated control variable. Using Hotelling's T2 statistic, first, each stage is tested for being out of control. Then out of control variables are selected using Murphy's method. The remainder of the research involves evalua...

introduction: papsmear test has been performed by public health services since 1991 in iran.   although cervix cancer is reported 9 th cause of death in four studied counrties in 1999, unfortunately detection rate of smear test is reported very low.  the aim of this study was to determine the cause of low sensitivity of papsmear in hamadan province- north west of iran. materials and methods : 1...

Double-dwell acquisition structures have typically been proposed as better alternatives to single-dwell structures from the point of view of the Mean Acquisition Time (MAT). Traditional approaches divide the double-dwell structure into an acquisition stage with short integration time, followed by a verification stage with longer integration time, which should provide a smaller global false alar...

Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...

Event relation knowledge represents the knowledge of causal and temporal relations between events. Shared arguments of event relation knowledge encode patterns of role shifting in successive events. A two-stage framework was proposed for the task of Japanese event relation knowledge acquisition, in which related event pairs are first extracted, and shared arguments are then identified to form t...

eurasian perch, perca fluviatilis l., is one of the most important species in european freshwater aquaculture and probably one of most important of cold freshwater species in nearest future. the aim of this study was to test the ovaprim in artificial reproduction in eurasian perch in two temperatures (12 and 14°c) with using new oocyte maturation stage system. the results obtained in present st...

In order to keep global competences, recent manufacturers have been utilizing product families to diversify and enhance the product performance by simultaneously designing multiple products under commonalization and standardization. Design information of product architecture and family is inevitably more complicated and numerous than that of a single product. Thus, more sophisticated computer-b...

We present a new feedback strategy implemented in a natural-language-generation-based e-learning system for German as second language (L2). Although the system recognizes a large proportion of the grammar errors in learner-produced written sentences, its automatically generated feedback only addresses errors against rules that are relevant at the learner’s current L2 acquisition stage. This app...

introduction: estrogen and progesterone are supposed to modify pain sensitivity. however, the actual role of each of these steroid hormones in this respect is not well known. plasma concentrations of these hormones show variation during estrous cycle. the role of alpha2 receptors in tonic pain has been pointed out. the aim of the present study was to investigate the agonist and antagonist effec...
