The global exploring feature of the surrogate model makes it a useful intermedia for design optimization. accuracy is closely related with efficiency optima-search. cokriging approach described in present studies can significantly improve and cut down turnaround time spent on modeling process. Compared to universal Kriging method, method interpolates not only sampling data, but also their assoc...

At this work, removal of Pb (II) using Lawsonia inermis (Henna) was studied. In recent years, use of low price adsorbent is taken into consideration. Adsorption experiments were performed in batch system at ambient temperature (25℃). The influence of some parameters such as time, initial metal concentration, pH and adsorbent dose were investigated. The optimum conditions was obtained at pH of 6...

turbulent fluxes in the atmospheric boundary layer are calculated using different models. one of the most popular and operational models in this groundwork is the second order turbulent model of mellor and yamada that has been widely used to simulate the planetary boundary layer (pbl). despite its popularity, it has been shown that this model has several weeknesses that affect its accuracy. the...

Abstract We introduce Hyper 2 LTL, a temporal logic for the specification of hyperproperties that allows second-order quantification over sets traces. Unlike first-order logics hyperproperties, such as HyperLTL, LTL can express complex epistemic properties like common knowledge, Mazurkiewicz trace theory, and asynchronous hyperproperties. The model checking problem is, in general, undecidable. ...
