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 o...

This paper presents a study of the relationship between Electrical Discharge Machining (EDM) parameters on the EDM efficiency factors using a full factorial design, based on pulse on-time, duty cycle and tool polarity parameters in EDM machining of AISI H13 tool steel. The results show that, in positive polarity, the plasma flushing efficiency and pulse efficiency increase according to the puls...

In a general fractional factorial design, the n-levels of a factor are coded by the n-th roots of the unity. This device allows a full generalization to mixed-level designs of the theory of the polynomial indicator function which has already been introduced for two level designs by Fontana and the Authors (2000). the properties of orthogonal arrays and regular fractions are discussed.

The present study is focussed on chromium removal by indigenous chromium-resistant microorganisms isolated from soil and sludge samples of an industrial site. optimal bioremediation conditions, namely temperature, hexavalent (Cr(VI)) initial concentration, pH time were determined using a full factorial design at two levels. results showed that the 54 bacterial strains, S10C1 identified as Bacil...

In this study, full factorial experimental design and Taguchi for the optimization of selected fabric quality parameters were examined comparatively with an study. The aim study is to show that Experimental Design can be used instead Full Factorial Design, which a classical experiment plan in textile engineering studies. developed outerwear woven dyeing-finishing enterprises; three different tw...
