In this paper, experimentally derived correlations of heat transfer and pressure drop are used in a Pareto based Multi-Objective Optimization (MOO) approach to find the best possible combinations of heat transfer and pressure drop of TiO2-water nanofluid flow in tubes fitted with multiple twisted tape inserts in different arrangement. In this study there are four independent design variables: t...

In this article we present a method to determine the band spectrum, band gaps, and discrete energy levels, of a one-dimensional photonic crystal with localized impurities. For one-dimensional crystals with piecewise constant refractive indices we develop an algorithm to recover the refractive index distribution from the period map. Finally, we derive the relationship between the period map and ...

This article highlights new spline-empowered computational methods for solving robust design optimization (RDO) problems in complex mechanical systems. The are predicated on a spline dimensional decomposition (SDD) of high-dimensional, discontinuous, or nonsmooth stochastic response statistical moment analysis, novel fusion SDD and score functions calculating the second-moment sensitivities wit...
