Robust estimation of support vector regression via residual bootstrap adoption
As current system designs grow increasingly complex and expensive to analyze, the need for design optimization has also grown. In this study, a more stable approximation model is proposed via the application o...

Choosing a suitable sample size in descriptive sampling
Descriptive sampling (DS) is an alternative to crude Monte Carlo sampling (CMCS) in finding solutions to structural reliability problems. It is known to be an effective sampling method in approximating the dis...

Noise reduction of muffler by optimal design
This paper proposes an optimal design scheme to improve the muffler’s capacity of noise reduction of the exhaust system by combining the Taguchi method and a fractional factorial design. As a measuring tool fo...
