Combined parallel and serial two shell-pass shell-and-tube heat exchangers (CPTSP-STHXs & CSTSP-STHXs) whose outer shell pass are set up continuous helical baffles have been proposed to enhance the heat transfer performance. The CPTSP-STHX and CSTSP-STHX are compared with the segmental baffled...

The first-principle theoretical studies about the effects of the electric field and oxygen vacancies on the structural relaxation of rutile titanium dioxide and the impacts of the relaxed structures on the capacitor-voltage curves are reported. The results show that oxygen vacancies in the same...

Latin hypercube designs have found wide application in computer experiments. A number of methods have recently been proposed to construct orthogonal Latin hypercube designs. In this paper, we propose an approach for expanding the orthogonal Latin hypercube design in Sun et al. (Biometrika...

Motivated by the effect hierarchy principle, Zhang et al. (Stat Sinica 18:1689–1705, <CitationRef CitationID="CR17">2008</CitationRef>) introduced an aliased effect number pattern (AENP) for regular fractional factorial designs and based on the new pattern proposed a general minimum lower-order confounding (GMC) criterion for choosing...</citationref>

Box-Behnken design has been popularly used for the second-order response surface model. It is formed by combining two-level factorial designs with incomplete block designs in a special manner--the treatments in each block are replaced by an identical design. In this paper, we construct small...
