The studied drying parameters were temperature, air velocity, mass of sand and drying time. The optimi...

in this study, taguchi experimental design has been used for the optimization of thickness of chromium layers. for this purpose brass materials have been electroplated under various conditions of the process. an orthogonal array (oa) was employed to analyze the effect of plating parameters on the characteristic of the thickness. variables which were considered for working were as following; amo...

CNC machine tool is widely used by manufacturing engineers and production personnel to quickly and effectively set up manufacturing processes for new products. This study discusses an investigation into the use of Taguchi Parameter Design methodology for study of CNC turning operation for surface roughness as a response variable. The Taguchi parameter design method is an efficient experimental ...

In this paper, solid base catalyst KF/CLW-Fe3O4 was prepared from carbide lime waste, primarily calcium hydroxide with tiny amounts of carbonate and; the used in optimization study on methyl ester production. The new strong synthesized by chemical impregnation. This characterized Hammett indicator analysis, Brunauer, Emmett, and Teller (BET), scanning electron microscope (SEM), X-ray diffractio...

Heating of the electrode at work–piece interface zone in spot welding, leading to degradation tip, becomes a significant concern high-volume production automotive industry. By recognizing interrelationship between hardness, wear resistance, and thermal conductivity, authors emphasize importance selecting materials with suitable alloying elements desirable for achieving optimal performance weldi...

The utilization of expanded polystyrene (EPS) beads in semi-lightweight concrete (SLC) intended for repair and building applications has gained great attention recent years. This study examines the effect mix design parameters including binder content, water-to-binder ratio (w/b), EPS silica fume (SF) additions on mechanical properties durability SLC mixtures. experimental program was carried o...

Taguchi methods, which are widely applied in industrial process design, were used to optimize DNA amplification finger-printing (DAF). Quadratic loss functions that penalize deviations from prediction values and L9 (3(4)) and L18 (3(8)) orthogonal arrays revealed effects and interactions of amplification reaction components and thermal cycling parameters. Analysis of variance (ANOVA) decomposed...

In recent years, breakthroughs in electronics technology have resulted upgrades the physical properties of metal oxide semiconductor field effect transistor (MOSFET) toward smaller sizes and improvements both quality performance. Hence, growth (GFET) is being promoted as one worthy contenders due to its superior material characteristics. A 14 nm horizontal double-gate bilayer graphene FET with ...

Friction stir welding (FSW) is a recent novel joining mechanism in the solid-state process. It extensively used to join similar and dissimilar materials as well. This research studied found optimum process parameters of FSW based on temperature simulation results 5-mm 6061 Al alloy sheet with butt joint configuration. Steady-state heat transfer analysis was performed using transient thermal wor...

This paper offers a different view of quality that has traditionally been used. Uniformity of products is of greater concern than just conformance to specifications. Improvement in quality by reducing the number of defectives is a goal every organization likes to pursue. However, the reduction of defectives requires an additional investment in procuring suitable technology and training of emplo...
