The green sand mould casting is an inevitable process to make large size and complex shape of the industrial components. quality in a significant phenomenon on quality. In this research, number ramming, thickness mould, percentage additives (western bentonite) mixing with have been considered study effects permeability hardness by L27 orthogonal array. Greensand experiments conducted industry o...

When an orthogonal array is projected on a small number of factors, as is done in screening experiments, the question of interest is the structure of the projected design, by which we mean its decomposition in terms of smaller arrays of the same strength. In this paper we investigate the decomposition of arrays of strength t having t + 1 factors. The decomposition problem is well-understood for...

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...

The present work analyses different parameters of end milling to minimize the surface roughness for AISI D2 steel. D2 Steel is generally used for stamping or forming dies, punches, forming rolls, knives, slitters, shear blades, tools, scrap choppers, tyre shredders etc. Surface roughness is one of the main indices that determines the quality of machined products and is influenced by various cut...

bubble column reactors are used in a wide variety of applications such as multiphase bioreactors, catalytic slurry reactors, and absorption processes. the superficial gas velocity-gas holdup relationship and transition point are two important parameters for characterizing the hydrodynamics of a bubble column reactor. in this study, systematic investigation of a nitrogen - water - glass beads bu...

In the published studies, to best of authors’ understanding, grey Taguchi-based statistical technique has not been applied for optimization combined gas-steam power plants. view this, seven essential input parameters namely compressor inlet air temperature, pressure ratio, fuel volumetric flow rate fuel, gas turbine maximum efficiency, and efficiency are chosen with aim determining optimal comb...

The underlying principles, techniques & methodology of robust design are discussed in detail in this report with a case study presented to appreciate the effectiveness of robust design. The importance of Parameter design & Tolerance design as the major elements in Quality engineering are described. The Quadratic loss functions for different quality characteristics are narrated, highlighting the...

Abstract—A number of studies have been conducted recently to investigate the influence of randomly oriented fibers on some engineering properties of cohesive and cohesionless soils. However, few studies have been carried out on freezing-thawing behavior of fine-grained soils modified with discrete fiber inclusions and additive materials. This experimental study was performed to investigate the ...

This current research focuses on optimizing the welding process parameters and penetration of 5052 alloys using a TIG based Taguchi methods. Process such as current, voltage, speed with three different levels were taken to form L27 orthogonal array design experiments. Analysis variance, signal-to-noise ratio analysis, regression analysis performed. The indicated that developed model has greater...
