1. In poultry investigations, the main interest is often to study the effects of many factors simultaneously. Two or three level factorial designs are the most commonly used for this type of investigation. However, it is often too costly to perform when number of factors increase. So a fractional factorial design, which is a subset or a fraction of a full factorial design, is an alternative. Th...

To solve the problem of great number of test cases, and to force the configuration testing to be effective, combinatorial testing is proposed, using an Orthogonal Array Testing Strategy (OATS) as a systematic, statistical way of testing pair-wise interactions. This combinatorial approach to software testing uses models to generate a minimal number of test inputs so that selected combinations of...

This research article presents the Quality by Design (QbD)-finalised conditions for a method that uses liquid chromatography-tandem mass spectrometry for the determination of concentration of enzalutamide (ENZ), an atypical anticancer drug, in a drug formulation and in spiked plasma samples. Critical process attributes (CPA) considered to be the influential parameters in separation, identificat...

A multi-response optimization problem was developed in search of an optimal parametric combination to yield favorable bead geometry of bead-on-plate weldments produced by submerged arc welding. Taguchi’s L25 orthogonal array design was employed to optimize the results within experimental limits. The objective functions were selected in terms of responses of bead geometry, viz. height of reinfor...

This paper investigates the effects of process parameters on weld bead width of austenitic stainless steel SS-310 in tungsten inert gas welding. The four parameters namely welding current, type of gas, gas flow rate and included angle of weld plates during butt joint were varied at three levels. The DOE approach was used to design experimental conditions. Orthogonal array L9 was used for carryi...

In this study, Al-Mg-Si alloy AA6061-T6 plates were joined in a seawater environment using the Submerged Friction Stir Welding (SFSW) technique, and process parameters optimized Taguchi L9 orthogonal arrays (OA). The considered tool rotational speed, transverse pin geometry. MINITAB-17 software was used to analyze responses signal-to-noise (S/N) ratio analysis of variance (ANOVA). optimum for t...

The utilization of TiB2 particles reinforced aluminum (Al6063) metal matrix composite materials in many different engineering fields has undergone a tremendous increase. Accordingly, the need of accurate machining of composites has increased enormously; an attempt has been made to assess the factors influencing surface roughness and material removal rate on machining the composite. The orthogon...

Organic filament-based lightweight materials are increasingly being used because of their high strength-to-weight ratio, recyclability, and low cost. The application nanofillers in addition to natural fibres is a fascinating one. main purpose the current experimental investigation manufacture estimate mechanical material nanocomposites. Natural like flax sisal as reinforcement; nanosilica parti...

In this study, the optimum process parameters for manufacture of brake friction linings (BFLs) from palm kernel shells (PKS), periwinkle (PWS), and coconut shell (CNS) composites were established using signal–to–noise ratio based on Taguchi technique. The L9(34) orthogonal array was set up investigation performance metrics (coefficient friction, wear rate, hardness) synergized by multiple crite...

In this research, optimization of the pulsed gas tungsten arc welding including pulse current, background current, pulse frequency and on time were investigated in welding of non-similar materials of austenitic stainless steel AISI 316L and nickel-base super alloy of Monel 400 by using ERNiCr3 filler metal. In order to obtain optimum conditions of welding the Taguchi method with the L9 array wa...
