Fuzzy Identification of Technological Objects

In practice, information on statistical characteristics of series mode interference is available only in certain cases. Moreover, for this or that reason input variables are measured inexactly, and their values can be specified with some uncertainty. The identification task is significantly complicated when the measuring signal passes through a natural channel with unknown statistical characteristics. This is, for instance, the case with well drilling when axial weight on the drilling bit and drilling bit rotations per minute are gauged by above-ground devices.

Типи лінгвістичних моделей та їх застосування для розв’язання лінгвістичних задач

This paper outlines understanding of the notions ‘model’ and ‘modeling’ in linguistics. The main linguistic models and their application to solving different linguistic tasks are described.

Застосування об’єктно-орієнтованого підходу до побудови моделі СППР

This article describes an object-oriented approach of DSS modeling. Three-level architecture is suggested and it describes a conceptual model of DSS. The analysis of possible reusable components for various types of structures is analyzed. We describe the principles of building a custom DSS use of multiple components.

Model optimize the performance of wireless sensor networks for optimality can select from transmission and activity schedule active/sleep sensor

The article examines the algorithm increase the lifetime of wireless sensor network. The model performance optimization using a range selection transmission and mode active/sleep sensors

Model based decision support system for forecasting financial processes

A computer based decision support system is proposed the basic tasks of which are adaptive     model constructing and forecasting of financial and economic processes. The system is developed with the use of system analysis principles, i.e. the possibility for taking into consideration of some stochastic and information uncertainties, forming alternatives for models and forecasts, and tracking of the computing procedures correctness during all stages of data processing.

Conception of quality management of city environment of city

The basic concepts of quality of city environment are considered, going near the management of quality of city environment, state of city environment for today, lacks of management,  raising of task of quality management of city environment. The system of aims  of quality management of city environment, choice of indexes of quality on the basis of this system and conceptual model of quality management, is offered.

Scheme model of a relational database presents a modified algebra algorithms

There DATABASE of the modified algorithms algebra for constructing mathematical models of patterns of relational databases is grounded. Mathematical models of abstract database schemes with one or many relations and abstract schema data warehouse are constructed.

The Model of Metal Oxide Particle Formation from Water Solutions of Salts

The model describing the formation of metal oxide particles from water solutions of salts was suggested. Dependence of instability constants of metal complexes and ionization constants of oxygen containing inorganic acids on the electron density upon the central ion or atom allows to calculate these values for metal hydroxides. Equations describing the number of metal ions in polyion, the concentration of polyions in solution, the number of metal ions in primary metal oxide particles and their concentration in the system were suggested.
