“…It is shown that though there are little differences between the percent contributions of Taguchi and Factorial methods, Factorial method, due to its production of higher R‐square values, can be more applicable and the results can be more accurate. It was also confirmed by the results of another study, showing that Factorial method is better than Taguchi method since the mean square error is less and the parameter design of the Factorial method provides a simple, systematic and efficient methodology for optimization process.…”

Nowadays, corrosion evaluation of steel embedded in reinforced concrete (RC) plays an important role in repair, protection and maintenance of RC structures. Air‐entraining agent (AEA) and microsilica (MS) are among the most important admixtures, which affect the corrosion rate (CR) of RC. Specifically, 12 mix designs incorporating different contents of AEA (ie, 0, 0.7, 1.4, 2.1, 2.9, and 3.6% by weight), half with 10% MS, were constructed. The corrosion behavior of RC specimens after exposure to 3.5% NaCl environment was investigated using half‐cell potential (HCP) and electrical resistance (ER) as conventional tests and Tafel polarization as a more powerful corrosion test. Moreover, an optimization process was conducted on the mix design parameters using Taguchi and Factorial methods to analyze the effective factors and sensitivity of CR to each factor. The results of Tafel test indicate that they are noticeably more reliable and reasonable as compared to HCP and ER tests. Moreover, the results show that incorporating a low content of AEA (up to 0.7%) effectively improves the corrosion behavior of RC specimens, while the mix design containing 0.7% AEA together with 10% MS is the optimal design in terms of a decreased CR. The results also show that Factorial is a more applicable method in the field of corrosion evaluation of RC, due to the yield of more accurate findings as compared to Taguchi.

“…Regression analysis allows predicting the value of the output intensity for better construction of a 3D shadow image when working with the instrument. The most important stage of building a regression model (regression equation) is the selection of the mathematical function form that most accurately defines the existing relations between the analyzed features [9][10][11]. In this case, intensity has been assigned as the depended attribute of the magnitude, and stress as the independent attribute respectively.…”

Abstract. There appear certain challenges in defining the dependence of the X-ray radiation intensity change in passing through the material (as fixed by the detector) conditioned by various parameters of an X-ray optical system while designing new modifications of X-ray tomographs. At present, this problem is experimentally solved by selection of voltage corresponding parameter values on an X-ray tube with thickness and type of the studied material considered. To reduce the design time and complexity, a mathematical model of parameter behavior is required to characterize the X-ray optical system in the major working range of values. The present paper investigates the X-ray optical system behavior using methods of mathematical statistics. A regression model has been obtained which matches the change of the X-ray intensity value to the intensity in the X-ray tube. The research has defined the further study direction of X -ray optical system parameters.

“…One of the most comprehensive approach in product or process developments is consider design of experiments (DOE). It is a statistical approach that attempts to provide a predictive knowledge of a complex, multi-variable process with few trials (Rafidah et al, 2014). One of statistical approach is Taguchi method that can optimize the process parameters and improve the quality of components that are manufactured.…”

Piezoelectric element is one of the best innovation and technologies to be utilized in energy harvesting to produce electrical energy from vibrations. It can give a perfect and independent arrangement solution that can be stored and used to power some wireless sensors, electronic device, and other low-power applications. With this goal in mind, a design and optimization of piezoelectric cantilever beam for energy harvesting has been developed. The focus of this paper is to discuss the design and optimization of piezoelectric cantilever beam by using Taguchi method for determine the optimal design parameters. For this study, the design of the bimorph piezoelectric harvester was performed by COMSOL software. Three parameters which are load resistance, width and length of piezoelectric cantilever has been considered. The parameters were optimized by using L16 orthogonal array Taguchi method. Optimization results showed that load resistance, width and length were found to be 10kΩ, 17mm, and 23mm respectively. The optimized outputs are 1.78mW electrical power at 5.97V for resonant frequency of 65Hz.
