A structural construction scheme for the hardware-software control complex of transmission pipeline electrochemical anticorrosion protection equipment is offered. Performance features of the complex under test operation according to the developed algorithms with the use of fuzzy logic methods.
Segmentation of competitors by revealing and ranging strategic grouping barriers of the retail trade enterprises with food products is considered.
Research results of the ultrasonic surface decontamination of the medical instrument in the complex with the structural material transformations occurring under the influence of ultrasonic vibrations are presented. The research work is aimed at the effective ultrasonic machinery modes selection.
Development of the pharmacy market of the Russian Federation causes severe competition among various pharmacy organizations. It results in progressive amalgamation of small-scale and medium-sized pharmacy enterprises.
A survey of enterprise development models as a single socio-ecological-economic system that takes into account the interaction of production and environment is made.
The problem of macro-economic importance of service industries and service economy development, as well as economic trends of service industries development in RF, and their dynamic growth factors are analysed. The Russian service practice innovations are featured.
An amphiphilic diblock copolymer, dextran-block-poly(ε-caprolactone) (DEX-b-PCL), with a series of welldefined chain lengths of each block was prepared by conjugating a dextran chain with a PCL block via aza-Michael addition reaction under mild conditions. For the dextran block, samples with relatively uniform molecul…
The place and role of innovations in the postindustrial period are analyzed. The current state and problems of the innovative sector of the Russian economy are evaluated. Stimulation factors of the enterprises innovative activity are studied.
Lagrange approach to solving problems of heat power plants hydraulic systems dynamics is stated. The calculations and experimental research data of starting-up processes of jet and vane pumps by filling hydraulic line canals of model plant with liquid are named.
Some aspects of the defuzzification method in fuzzy expert information processing in the expert system for technological regulation of the machines are considered. An example of the method implementation is given in the article.
A behavioral model of rheological bodies (viscoelastic material, configuration or system) under load control action, operating in the predetermined fashion for a time, is offered.
Presentation algorithm of the closed contour in sceletons collection is presented. Sceletons collection represents sequence of segments which connect circle centers. Circles fit into the generated contour segment. The major direction of algorithm usage is text information processing without setting up the certain type…
The basic semiotic terms – sign, symbol, emblem – are analyzed. Generalization of the existing notions allows to state that signs are things, objects, or phenomena which denote other things, objects, or phenomena. Symbol can be considered a variety of sign, it is socially significant, emotionally expressive, and polys…
