Indicator Function and its Application in Two - level

چکیده
State University of New York at Stony Brook 2A two-level factorial design can be uniquely represented by a polynomial indicator function. Therefore, properties of factorial designs can be studied through their indicator functions. This paper shows that indicator function is an effective tool in studying two-level factorial designs. Indicator function is used to generalize aberration criterion of a regular 2−level fractional factorial design to all 2−level factorial designs. An important identity of generalized aberration is proved. The connection between a uniformity measure and aberration is also extended to all two-level factorial designs.

The Safety Level of Railway Infrastructure and Its Correlation with the Cost of Preventive and Mitigation Measures
This paper develops a methodology which allows the correlation between the cost which is required for the application of preventive and mitigation measures dealing with accidents which occur within a railway system and the improvement of the level of safety as a result from their implementation. The safety level is expressed either quantitatively, by the decrease of “fatality risk” indicator...
متن کاملMeasurement of Plain Weave Fabrics Density Using Fourier Transforms
Warp and weft spacing and its coefficient of variation affect the physical properties of fabrics such as fabric hand, frictional and mechanical properties. In this paper the weft and warp spacing and its coefficient of variation for plain weave is calculated using Fourier transforms. Different methods have been used in this work including autocorrelation function. First, two dimensional power s...

متن کاملUse of Two Smoothing Parameters in Penalized Spline Estimator for Bi-variate Predictor Non-parametric Regression Model
Penalized spline criteria involve the function of goodness of fit and penalty, which in the penalty function contains smoothing parameters. It serves to control the smoothness of the curve that works simultaneously with point knots and spline degree. The regression function with two predictors in the non-parametric model will have two different non-parametric regression functions. Therefore, we...
