The objective of this work is to optimize the control parameters of the direct injection (DI) single cylinder diesel engine with respect to NOx (Oxides of Nitrogen) and fuel emissions through experimental investigations and Taguchi method. A single cylinder 5.2 kW diesel engine was selected for this experiment. Five parameters such as clearance volume, valve opening pressure, nozzle-hole diamet...

In this current era of competitive machinery productions, the industries are designed to place more emphasis on the product quality and reduction of cost whilst abiding by the pollution-preventing policy. In attempting to delve into the concerns, the industries are aware that the effectiveness of existing lubrication systems must be improved to achieve power-efficient and pollutionpreventing ma...

Purpose: This study aims to examine the interaction between process parameters and bead geometry, to perform the research to predict optimal bead geometry (bead width, reinforcement height, left leg length, right leg length) through the analysis of experimental data. For this, not only linear and the curvilinear equations were developed to predict bead geometry, but also interactions between pr...

In machining to improve machinability, productivity and to extend tool life coolants and lubricants where used .Increasing industry the use of cutting fluids subsequently increasing this leads in reduce of living conditions nearby future all the governments recommend the manufacturers to reduce the usage of toxicity cutting fluids. Still research for dry machining challenge is exiting for the i...

A hybrid Taguchi-based genetic algorithm (HTGA) is developed for solving multi-objective flowshop scheduling problems (FSPs). Search performance is improved by using Taguchi-based crossover to avoid scheduling conflicts, and dynamic weights are randomly selected by a fuzzy inference system. The conventional approach to selecting dynamic weights randomly ignores small value for the objective whe...

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...

An important issue in multi-channel manufacturing (MCM) design is the channel formation process. In this study, the control parameters that affect the performance of genetic algorithms (GAs) developed to solve channel formation problem, are examined and the optimum values of such parameters are explored using Taguchi method. Two types of problems were taken into account in terms of machines, pa...

Many factors may influence the successful development of software (SW). Most practitioners, however, tend to use their own preferred methods—some ad hoc—for this task. This paper reviews recent attempts of using orthogonal array (OA) experiments to determine the effect of various influencing factors and then their optimum settings to reduce errors in the SW created. Genichi Taguchi popularized ...

Phased antenna array design is one of the most important electromagnetic optimization problems. This research combined the Taguchi method and artificial intelligence methods, used them as the prediction tool in designing parameters for the communication system, and then constructed a set of the optimal parameter analysis flow and steps. In this paper, we present an application of artificial neu...
