This paper presents the application of Taguchi approach in investigating the performance of mobile ad hoc networks (MANETs) with respect to drop rates. The performance of MANETs was influenced very much by the routing protocol designs and quantitative factors such as network size, terrain, pause-time, node speed, transmission range, traffic load, and packet rates. The NS-2 simulator was used fo...

In this paper, we proposed a weighting factor estimation method for peak-to-average power ratio (PAPR) based on Taguchi-genetic algorithm (TGA) in an orthogonal frequency division multiplexing (OFDM) systems. Partial transmit sequences (PTS) is one of the most attractive schemes to reduce the PAPR in OFDM systems. However, the conventional PTS scheme requires an exhaustive searching over all co...

In this paper we present a new cooperative coevolution hybrid Taguchi-genetic algorithm (CCHTGA) to solve high-dimensional optimization problems with continuous variables which are typical in large scale systems. The CCHTGA employs cooperative coevolution frame to decompose the problem into several subsystems and adopts a novel decomposition technique “random grouping strategy”. Subsystem optim...

Vacuum brazing products have excellent joining quality, less deformation and fewer residual stresses. The vacuum brazing technique has significant effect on the microstructure and property of the aluminum brazed joint, but there is little discussion about the optimization of the process. This study investigates how different process parameters affect the tensile properties of 6061-T6 aluminum v...

The paper envisages the study to optimize the effects of process variables on surface roughness, MRR and power consumption of En24 of work material using PVD coated tool. In the present investigation the influence of spindle speed, feed rate, and depth of cut were studied as process parameters. The experiments have been conducted using full factorial design in the design of experiments (DOE) on...

The Mahalanobis-Taguchi System is a diagnosis and forecasting method for multivariate data. Mahalanobis distance is a measure based on correlations between the variables and different patterns that can be identified and analyzed with respect to a base or reference group. This paper presents a comparison of the Mahalanobis-Taguchi System and a standard statistical technique for defect detection ...

An experimental study has been carried out to simultaneously optimize several diesel engine designs and operating parameters for low exhaust emissions using Taguchi method. A single cylinder (DPF make) diesel engine equipped with a high pressure, cam driven mechanical injector has been used in this experiment. The effects of changes in engine design/operating parameters–nozzle spray holes, pist...

Injection moulding is one of the most popular polymer processing methods due to its high production rate as well as its ability to produce very intricate geometries at very cheaper cost and within few seconds. There are several flaws which occur while producing plastic parts by Injection moulding, like warpage, shrinkage, flash, sink marks etc. Shrinkage is one of the most critical problems whi...

Present work highlights application of utility theory combined with Principal Component Analysis (PCA) and Taguchi’s robust design for simultaneous optimization of correlated multiple surface quality characteristics of mild steel machined product prepared by straight turning operation. The study aims at evaluating the most favorable process environment followed by an optimal parametric combinat...

Genotyping of thiopurine S-methyltransferase (TPMT) is recommended for predicting the adverse drug response of thiopurines. In the current study, a novel version of allele-specific PCR (AS-PCR), termed competitive real-time fluorescent AS-PCR (CRAS-PCR) was developed to analyze the TPMT*2 genotype in ethnic Chinese. This technique simultaneously uses wild-type and mutant allele-specific scorpio...
