Glass is an ideal material for parts with micro-holes and has been widely used in automotive, aerospace and woodworking industries due to its superior wear and corrosion resistance. In this research paper, the statistical analysis of the ultrasonic machining of glass using design of experiments and regression approach has been done. The performance characteristics such as material re moval rate...

Received: 20 October 2014 / Accepted: 15 November 2014 Abstract: An approach for determination of the best cutting parameters leading to maximum material removal rate in machining D2 (Die Steel) on vertical milling centre is used. The Response Surface Methodology technique is applied to obtain optimum values of considered parameters in machining D2 (Die Steel) with four flutes carbide end mill ...

Positioning of mobile robots basically calculated using odometry information. Odometry from the wheel’s encoder is mostly used for simple and inexpensive implementation for determining the relative localization of a mobile robot. This paper deals with the estimation of better relative localization of a two wheeled differential drive robot by means of odometry by considering the influence of par...

In serial production, problems are constantly encountered in the selection of welding parameters due to excess and variations. order compensate for these variations, mostly high energy flux is used. this study, an approach developed estimate weld nugget diameter determining sheets with a thickness 0.6-3 mm introduced. Minitab statistical program was used create experimental data mathematical op...

Hal ini hingga berdampak kebutuhan komponen pendukung salah satunya adalah Plate Ramp. Permasalahan timbul terkait fluktuatif menyebabkan adanya kesulitan untuk merencanakan produksi optimal. Tujuan penelitian mengetahui model peramalan paling baik digunakan menentukan opt...

The incident and problem management process forms an essential part in every organization. Since businesses rely heavily on IT, each outage, issue or user service request should be dealt with as quickly as possible in order to minimize its impact on operations. For Volvo IT Belgium, we analyzed the event log file of an incident and problem management system called VINST, in order to objectively...

When population variances of observations in an ANOVA are a known function of their population means, many textbooks recommend using variancestabilizing transformations. Examples are: square root transformation for Poisson data, arcsine of square root for binomial proportions, and log for exponential data. We investigate the usefulness of transformations in onefactor, 3-level ANOVAs with nonnor...

This handout illustrates two-factor ANOVA with both factors being fixed effects. Two versions of essentially the same data set are used: (A) a completely balanced data set, i.e. one in which there is equal replication of each treatment combination [this is a sub-set of the actual data set]; and (B) An unbalanced data set, with unequal replication of treatments but all treatment combinations pre...
