let f, g and h be all entire functions of several complex variables. in this paper we would like to establish some inequalities on the basis of relative order and relative lower order of f with respect to g when the relative orders and relative lower orders of both f and g with respect to h are given.

Conservation biologists mostly agree on the need to identify and protect biodiversity below the species level but have not yet resolved the best approach. We addressed 2 issues relevant to this debate. First, we distinguished between the abstract goal of preserving the maximum amount of unique biodiversity and the pragmatic goal of minimizing the loss of ecological goods and services given that...

Such limited-use credit cards limit the exposure of a traditional long-term credit card number, particularly in Internet transactions. These offerings employ an on-line solution, in that a credit card holder must interact with the cre...

Delta-certificate revocation lists (delta-CRLs) were designed to provide a more efficient way to distribute certificate status information. However, as this paper shows, in some environments the benefits of using delta-CRLs will be minimal if delta-CRLs are used as was originally intended. This paper provides an analysis of delta-CRLs that demonstrates the problems associated with issuing delta...

Too often, the separate lines of business operate independently and information available to one line of business may not be used productively by others. In this study, we examine the potential of using information from customers ...
