An encryption technique is widely used to keep data confidential. Most of the block symmetric algorithms use substitution functions. Often this functions use so called S-BOX matrix. In this paper author presents one software tool for testing and measuring square s-boxes. Based of information theory functions for testing static and dynamic criteria are presented. These criterions are mathematica...

The theoretical foundation for a number of model selection criteria is established in the context inhomogeneous point processes and under various asymptotic settings: infill, increasing domain combinations these. For Poisson we consider Akaike's information criterion Bayesian criterion, particular identify process analogue ‘sample size’ needed criterion. Considering general derive new composite...

In many applications, large volumes of time-sensitive textual information require triage: rapid, approximate prioritization for subsequent action. In this paper, we explore the use of prospective indications of the importance of a time-sensitive document, for the purpose of producing better document filtering or ranking. By prospective, we mean importance that could be assessed by actions that ...
