In this study the cyclic linear random process, which combines the properties of linear random process and cyclic random process, is defined. This expands the possibility of describing cyclic signals and processes within the framework of linear random processes theory and generalizes their known mathematical model as a linear periodic random process.

This article is about the determination of the process of deleting formulas of algorithms. The algorithm of computer deleting of formulas of algorithms was given. Synthesized, minimizing the mathematical model was synthesized, minimized and the algorithm of deleting of formulas of abstract algorithms was studied.

This paper belongs to the field of systems engineering and is aimed at improving the qualitative indices of vector data information technologies (e.g. 2D vector data coding design) with respect to reliability, precision and other significant operating characteristics of the systems based on the combinatorial configurations theory, namely the Ideal Ring Bundles (IRB)s.

This article examines a question of basic factors that affect the efficiency of IT investments. Structural components and the effect on investment were investigated. A multi objective model of investment allocation in IT for the period and election of the initial date of investment was proposed. The methods for making decision and elaborated recommendations for using these methods were analysed.

This article is about determination of properties of unitherms. The algorithm of calculating geometrical parameters of unitherms is introduced. The mathematical model is synthesized. This model is then minimized and built. The algorithm of calculating geometrical parameters of unitherms is probed into.
