Due to the widespread use of titanium alloy in various applications, such as maritime transportation and aviation, process mass production this material has become more challenging. Traditional methods removing materials have high wear rates slow processing speeds. This prompted development new techniques that can handle complexity material. Wire Electrical Discharge Machining (WEDM) is a metho...

The current research deals with Taguchi-coupled grey relational analysis (GRA) multiobjective optimization of wire electric discharge machining (WEDM) for better surface roughness (Ra) and the material removal rate (MRR) over magnesium/halloysite nano tube/zirconium (Mg/HNT/Zr) metal matrix composite (MMC). Hybrid composites are created through powder metallurgy route by varying weight percenta...

surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. a good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. on the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and incr...

This investigation proposes a grey-based Taguchi method to solve the multi-response problems. The grey-based Taguchi method is based on the Taguchi’s design of experimental method, and adopts grey relational analysis (GRA) to transfer multiresponse problems into single-response problems. In this investigation, an attempt has been made to optimize the drilling process parameters considering weig...

The increasing technological inventions like cellular phones and GPS devices, we observe increasing number of distractions to divert the driver’s attention. This distraction has led to increasing number of accidents on road, which brings a need of a Drowsiness Detection System that calculates various eye parameters to help the driver stay alert. This type of system brings about alertness and ac...

Buffer management (BM) is an inventory management methodology introduced by theory of constraints (TOC). In this practice, the retailer passes his demands to the vendor in ‘almost a daily manner’ and has a ‘dynamic inventory buffer’ that reflects the change in demand patterns allowing the vendor the opportunity to replenish his inventory and obtain some market information. In this paper, we con...

A methodology is proposed to jointly model treatments with quantitative levels measured throughout time by combining the response surface and growth curve techniques. The model parameters, which measure the effect throughout time of the factors related to the second-order response surface model, are estimated. These estimates are made through a suitable transformation that allows to express the...

The attitudes and response of “policy receivers” should be taken into more consideration when governments make regulation policy. This paper discusses the public’s degree of understanding, support willingness, implement willingness, and influence willingness to the policy, as well as the mutually responding scenario by using the quadratic response surface regression analysis from the perspectiv...

This paper investigates the use of Kriging in random simulation when the simulation output variances are not constant. Kriging gives a response surface or metamodel that can be used for interpolation. Because Ordinary Kriging assumes constant variances, this paper also applies Detrended Kriging to estimate a non-constant signal function, and then standardizes the residual noise through the hete...
