Cryptographic properties of modified AES-like S-boxes

Galton Board with memory

The Galton Board model complemented with a simple memory mechanism was employed to illustrate the Galton Table structure

Comparison and evaluation of registration methods of intra-oral radiographs images

This paper presents comparisons and evaluations of registration methods of intra-oral radiograph images. Several automatic and manual algorithms were examined. Three similarity functions for automatic registration are described and evaluated. In addition, the results of two manual registration tests are compared for both 3 and 10 control points marked interactively by the operator.

Tabulating families of functions with symmetries

We propose a general algorithm which aims at optimizing the usage of computer resources for tabulating families of functions possessing known symmetries. The approach is based on the group theoretical description of symmetry relations among the functions and their parameters, where orbits play a crucial role.

Algorithms for finding the maximal length quasiplateau interval of the experimental curve

There exist some problems related to the determination of the quasiplateau region in experimental sciences. The paper describes two approaches to this matter which lead to two algorithms for finding the maximal length quasiplateau interval for discrete data. Numerical tests are presented.
