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).
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.
Now for the developed countries of the world community is inherent to ensure quality by organizational and management measures, namely development, implementation, certification and continuous improvement of quality systems. Proceedings of the outstanding scientists of the twentieth century W. Shewhart, W. E. Deming, Joseph M. Juran (first introduced the concept of “quality control”), F. Crosby, K. Ishikawa, Armand V. Feigenbaum, H. Taguchi, T. Seyfi formed a modern strategy based on the application of quality management systems (QMS).
Vegetables has a number of specific properties that aremanifested in consumption, storage and processing of vegetables. The study is the formation and systematization of quality vegetable products to develop common principles for the evaluation and determination of complex quality indicator taking into account the needs of different profiles of consumers.
This article presents the features of functioning the cyber-physical systems and their components. The cyber-physical systems are complex systems which components may be located at great distance from one another. The cyber-physical systems perform processing of information and functions of monitoring and control equipment. Cyber-physical systems infrastructure mainly consists of subsystems, which electronic components are implemented through the embedded system control and get information about the environment through sensors and measuring device and can influence it through actuators.
Existent approaches to determination of basic concepts of information theory, coming from the statistical reasoning (classic approach), theory of algorithms (algorithmic approach) and theory of pattern recognition (vivid approach) are examined. Their comparative analysis is conducted. Approach which enables in number to estimate the value of information is offered.
The scientific and practical problem of automatic detection of meaningful keywords and Ukrainian content categorization in Internet systems on the basis of linguistic analysis of text information is unleashed. The article presents a theoretical and experimental substantiation of linguistic analysis methods for Ukrainian content using Porter stemming.
This article is about determination of process of adaptation, data structure of algorithms editor. Mathematical model of data structure of algorithms editor, hierarchical-modular construction principle of editor, of adaptation process and expanding and collapsing processes were synthesized, minimized and built.
