CNC turning is widely used as a manufacturing process through which unwanted material is removed to get the high degree of surface rough. In this research article, Taguchi technique was coupled with grey relation analysis (GRA) to optimize the turning parameters for simultaneous improvement of productivity, average surface roughness (Ra), and root mean square roughness (Rq).Taguchi technique L2...

In this paper, Vacuum Assisted Resin Transfer Molding (VARTM) method was simulated by analytical solution. Then the effect of parameters like fiber density, distribution of layer thickness, perform layer thickness, resin viscosity was investigated theoretically. Obtained results show that by selecting optimum distribution layer thickness, increasing fiber volume fraction, reducing viscosity of ...

The Taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(PHB) production by Ralstonia eutropha. The optimum condition was obtained as: fructose concentration, 15 g/L; C/N ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° C; seed age, 15 h. At optimu...

A hybrid algorithm by integrating an improved particle swarm optimization (IPSO) with successive quadratic programming (SQP), namely IPSO–SQP, is proposed for solving nonlinear optimal control problems. The particle swarm optimization (PSO) is showed to converge rapidly to a near optimum solution, but the search process will become very slow around global optimum. On the contrary, the ability o...

We investigate fast optimum route planning in large, real-world road networks for car navigation systems. We show how graph partitioning can be used to increase the speed of planning optimum routes. Creating a graph partition with future route planning in mind leads to a non-standard graph partitioning problem. In particular, the quality of a partition, indicated by the objective value, is assu...

This study was carried out to optimize cholesterol removal in whole egg using crosslinked β-cyclodextrin (β-CD) and to recycle the β-CD. Various factors for optimizing conditions were concentration of the β-CD, mixing temperature, mixing time, mixing speed and centrifugal speed. In the result of this study, the optimum conditions of cholesterol removal were 25% crosslinked β-CD, 40°C mixing tem...

this study was conducted to investigate the effect of soil moisture content in primary tillage and travel speed during disking operation on the performance of an offset disk harrow in a silty clay loam soil. at first, the effect of three soil moisture content ranges of (12-14), (14-16) and (16-18) percent (dry basis) on soil clod size (left from moldboard plowing) was investigated. then, the pe...

the influence of 0-27 g/100g of full-fat soy flour (ffsf), 31-35g/100g of water content and extrusion conditions on the textural characteristics of spaghetti were evaluated. process was performed with screw speed of 10-40 rpm and water circulating temperature of 35-70°c. this enrichment resulted in significant differences in mechanical strength and cutting parameter. based on the mixture surfac...
