among the several non-conventional processes, electrical discharge machining (edm) is the most widely and successfully applied for the machining of conductive parts. in this technique, the tool has no mechanical contact with the work piece and also the hardness of work piece has no effect on the machining pace. hence, this technique could be employed to machine hard materials such as super allo...

The objective of the present study is to optimize the process by applying the Taguchi method with orthogonal array robust design. Taguchi Parameter Design is a powerful and efficient method for optimizing the process, quality and performance output of manufacturing processes, thus a powerful tool for meeting this challenge. Off-line quality control is considered to be an effective approach to i...

manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. the material removal rate is a significant indicator of the productivity and cost efficiency of the process. taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering thr...

The Analysis of Variance (ANOVA) is a commonly used statistical test in Statistics. The test compares the equality of means against the alternative that at least one of the means are different. In this report, we introduce a multivariate test known as Wavelet Analysis of Variance extending ANOVA to profile (functional) data. The test exploits the dimension reduction, noise elimination propertie...

The purpose of this study was to investigate the minimum acceptable viewing angle (MIAVA) for different age groups while reading the Chinese e-book. Ninety subjects participated in this study. Their age ranged from 21 to 70 years, and they were divided into three age groups, i.e. young, middle, and old groups. Each subject was firstly asked to adjust personal preferred viewing distance. The min...
