New equation and algorithm are developed for non-iterative calculating flowrate of fluid energy carrier for pressure differential flowmeter based on long radius nozzle. This equation implicitly contains three build-in iterative cycles for calculating flowrate. According to the results of comparing the flowrate values obtained by developed non-iterative algorithm to the flowrate values by standard iterative algorithm, the authors found that the developed non-iterative algorithm ensures the accuracy of flowrate calculation specified by the requirements of DSTU GOST 8.586.5:2009.

The available means of ordering and sorting in some important sections of discrete mathematics and computer science are studied, namely: in the set theory, classical mathematical logic, proof theory, graph theory, POST method, system of algorithmic algebras, algorithmic languages of object-oriented and assembly programming. The Cartesian product of sets, ordered pairs and ordered n-s, the description by means of set theory of an ordered pair, which are performed by Wiener, Hausdorff and Kuratowski, are presented. The requirements as for the relations that order sets are described.

In the article were researched the principles of building systems for observation and recognition of objects. Also we have given the classification of human faces recognition methods. Authors have analized the features of operetion for the progressive calibration network (PCN) for human face recognition. And finally has been created and tested the developed face recognition algorithm as the realized software system.

In wireless sensor networks, the clustering method is often used to transmit information, which is one of the most energy efficient approaches. Since the master cluster node interacts with other nodes in the network, a node with a high residual energy is selected to perform its functions. The technology of selecting the main node based on fuzzy logic, which involves the use of a number of input parameters, the effect of which is demonstrated in the article, is proposed.

The comparative analysis of the most common systems of computer mathematics is made and their structure is described. The main functions of the systems of computer mathematics are determined and benefits and disadvantages of using the systems Derive, Mathematika, Matlab, Mathcad, Maple, MuPad, Gran, GeoGebra are directed. The Ukrainian software tool Gran is described which is used for graphical analysis of functions (Gran1), the systems of geometrical objects on the plane (Gran-2D) and objects in space (Gran-3D).

Проаналізовано відомі підходи та алгоритми до проектування гібридних сховищ даних. Запропоновано концепцію узагальненого гібридного сховища даних.

The processes of transforming the algorithm algebra formulas are described. The algorithm for calculation of geometrical parameters of unithrams is given. Synthesized, minimized, built a mathematical model and investigated the algorithm of the transformation process of algebra algorithm formulas.

Some measures of similarity of speech signals fragments, which are used for their recognition are considered. The algorithm and program complex for signal processing are developed.

In expanding the known classical algebra algorithms received meaningful input operations elimination, introduced a new extension. At the level of innovation is the introduction of the alphabet in special unitermiv, what are the signs uniterm return cycle and conditional uniterm cycle. At the level of innovation definitions of operations is an axiom uniterma input and output in the region of the operation cyclic sequencing, axiom input and output uniterma in scope and with the operationcyclic elimination, input and output axioms uniterma in scope and operation cyclic paralleling.
