Calibrations to existing cost of doing business in space indicate that to establish human presence on the Moon and Mars with the Space Exploration Initiative (SEI) will require resources, felt by many, to be more than the national budget can afford. In order for SEI to succeed, we must actually design and build space systems at lower cost this time, even with tremendous increases in quality and...

Nowadays, the internet and social networks become more popular than ever. People in all ages use the internet and communicate by that. One of the most terrible events in our daily life is to disconnect from the internet and lose the connections. It may also influence on the economics; so the sustainability in this area is necessary. Internet service provider companies are the executors of selli...

In this work, a hybrid Taguchi-Particle Swarm Optimization (TPSO) is proposed to solve global numerical optimization problems with continuous and discrete variables. This hybrid algorithm combines the well-known Particle Swarm Optimization Algorithm with the established Taguchi method, which has been an important tool for robust design. This paper presents the improvements obtained despite the ...

In this paper the effect of rotor geometry parameters on the d-axis and q-axis inductance of synchronous reluctance machines is investigated and an optimum design parameter combination is achieved to improve the saliency ratio as well as the performance of drive system. The 2D finite-element model of synchronous reluctance machine is used to construct the Taguchi design of experiments. The leve...

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 the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...
