Article history: Received January 1 2012 Received in revised format April 15 2013 Accepted April 15 2013 Available online April 15 2013 Cutting force and chip reduction coefficient is the important index of machinability as it determines the power consumption and amount of energy invested in machining actions. It is primarily influenced by process parameters like cutting speed, feed and depth o...

The determination of the target for a manufacturing process involves a complex and fiscally vital decision. This study examines a situation where a product is classified into several grades with respect to specifications of markets. It is reasonably assumed that each grade gives its price and manufacturers cannot produce every item in good grade due to uncontrollable variation of product perfor...

In this article we emphasize the manner in which this statistical indicator the variation coefficient (v) could help the inference on measurable characteristics generated by technological processes. Our interest lies upon the so-called SPCStatistical Process Control; the main result obtained is the following: if the coefficient of variation is known, then the statistical distribution of capabil...

The Analytic Hierarchy Process (AHP) is a useful method in aggregating group preference. We suggest a new method that uses consistency ratio as group evaluation quality. For this method, we introduce Taguchi's loss function. We also develop an evaluation reliability function to derive group weight. Lastly, we perform four experiments in order to confirm validity of this method. 1. Introduction ...

We describe and analyze two stochastic methods for `1 regularized loss minimization problems, such as the Lasso. The first method updates the weight of a single feature at each iteration while the second method updates the entire weight vector but only uses a single training example at each iteration. In both methods, the choice of feature/example is uniformly at random. Our theoretical runtime...

Methods for assessing hearing loss in human loss in human and in animal are reviewed with special reference to the use of brainstem auditory evoked potentials (BSEP). The technique of recording and digital filtering of BSEP is described and compared with the results obtained by use of traditional analog filtering. The use of electrophysiological methods in assessing threshold shifts in studies ...
