1.1 This guide covers the specification of appropriate boundary conditions that are an essential part of conceptualizing and modeling ground-water systems. This guide describes techniques that can be used in defining boundary conditions and their appropriate application for modeling saturated gro...

1.1 This guide covers techniques and procedures used in defining initial conditions for modeling saturated ground-water flow. The specification of initial conditions is an essential part of conceptualizing and modeling ground-water systems.

1.1 This guide covers the development of a galvanic series and its subsequent use as a method of predicting the effect that one metal can have upon another metal when they are in electrical contact while immersed in an electrolyte. Suggestions for avoiding known pitfalls are included.

The optimization policy of the purchase price and the profit under vendor managed inventory (VMI) is studied. For a salable product, supply chain mode of VMI is established, which is based on deterministic demand, having initial stock and having stock-out cost. With the further analysis of the mode,...

The conceptions of the knowledge screen generated by S-rough sets are given: f-screen and $\bar{f}$-screen, and then puts forward $\bar{f}$-filter theorem, $\bar{f}$-filter theorem of knowledge. At last, the applications of knowledge separation are given according to...
