The conventional methods of a choice of the most effective version of land tenure are analyzed. It is offered to use instead of them an expert method of the analysis of hierarchies. The diagram of a choice of the most effective version of land tenure on the basis of this method is represented. The degree of influence of various factors on a choice of the most effective version of use of the ground on an example of interrogation of experts in a Rostov-on-Don is certain
Keywords: Assessment, effective, land tenure, methods, expert, factors, hierarchy
Considered original interpolation method of the working tool path using confluent two-unit manipulator. This method is based on the separation of the links on the master and slave and the use of polar coordinates to determine the incremental rotation of angle units. It is adapted for use calculating hardware with floating point.
Keywords: two-tier mechanism, circular interpolation, the kinematic model, floating point operations, the static accuracy of interpolation
One of the main conditions for effective use of resources is a methodically correct determination of the price of land. Analyzes approaches to the development of science-based methodology for determining the price of the land. Innovation-oriented approach to the use of urban land is especially important, since the city as opposed to rural areas there are so many competing uses of the site
Keywords: Resources of the city lands, cost, a policy concerning the city lands, an innovative principle, effective
The method of estimating of generator frequencies for radio-electronic devices based on coupling treatment of formed signal phases is considered. The correlations setting the correspondence of potentially achieved accuracy of frequency estimations for each generator to their number and parameter values are presented.
Keywords: generator, frequency estimation, function of maximum likelihood estimation, estimation of dispersion
The methodology, language and tools for rapid development of logic models of systems and processes are proposed. Language is defined in the first-order predicate calculus with equality and a representation of negatives, modules, discrete time intervals. The proposed computable mathematical semantics allows to construct interpreters whose complexity is O(nlogn) relative to the power of models. Interpretations result is a model derivated from the logical specification of objects by direct inference. The model can be used as a working prototype of the system. The technology is designed to address a wide range of problems of language analysis, projects, processes, development of training and expert systems.
Keywords: logical model, predicate calculus, logical mistakes, logical semantics, analysis, interpreter

The work investigated the cathode intercalation process alkali metal platinum under the influence of the alternating pulse current of aqueous and non-aqueous solutions containing alkali metal cations. By means of the method of pulse chronopotentiometry found that processes taking place at the platinum cathode polarization in water (neutral and alkaline) and in non-aqueous electrolytes include electrochemical adsorption and intercalation of solvent molecules into the adsorption layer of alkali metal ions. When this surface is oxidized in the intercalation platinum milder than pure platinum.
