Development of principles, methods and schemes of transmission, receiving and processing of signals with a total bandwidth 1-10 GHz

The country is increasingly developing high-speed railway traffic comfortable express trains, highways are built for high-speed vehicles. The velocity of these objects reach 200-300 km / h, respectively. There is therefore a need to ensure passenger services 4G. The purpose of this project is to develop principles, methods and schemes of transmission, reception and processing of signals with a total operating frequency band 1-10 GHz and 4G services to subscribers in mobile terminals (MT), moving in carpool and express train at a speed of 300 to 200 km / h.

Research of adaptive methods of increase of efficiency of broadband radioaccess systems

The new link adaptation method was created based on multicriteria channel state estimates with fuzzy logic mathematical apparatus. Matching link adaptation algorithms were created with usage of unusual improved fuzzy inference algorithm based on both link state energy estimations and multicriteria estimations (energetical, probabilistical, and statistical). The rules of membership function construction were determined. They are constructed by direct methods based on simulation results or laboratory measurements of stationary channel immunity.

Fundamental principles of the new creation methods for the synthesis of nanocomposites and nanostructured materials with specified functional properties (Comprehensive Project)

A new fundamental scientific concept of purposeful synthesis of metal oxides and nanocomposites «metal oxide/multiwalled carbon nanotubes» structure with controlled and predetermined properties, which may be used as photocatalysts and electrocatalysts, energy conversion devices is created. Conceptual bases of alternative methods (high-temperature electrochemical synthesis and recovery metallothermal) direct synthesis of nanostructured silicides metals VI-B group are proposed.

The general theory of information technology software design hobs

Given the nature of the process of hobbing developed a general theory of information technology software design hobs, which is the basis for creating a new level of CAD this tool. Creation of CAD based on it will allow the design stage hobs by determining the effect of process parameters and design parameters of gear milling tool accuracy and performance gear cutters to predict not only the accuracy of the wheels with less of their production, and to develop new and more progressive design hobs.

Development of the generalized lifetime prediction method for composite structural elements at complex low-cycle loading with damage

The main result of work consists in development new physical equations theory of cyclic elastic-viscos-plasticity at complex technological and operational thermo-power loading; methods of theoretic-experimental lifetime calculation new products and residual lifetime definition of the responsible high-loaded designs elements machine-building complex different function at a stage of their operation.

Mechanisms of intensification of sorption process of heavy metal ions by the magnetically controlled biosorbents for the purification of the waste water

New mechanisms for the intensification of the process of heavy metal ions sorption by magnetically modified biosorbent, based on yeast S. cerevisiae for wastewater treatment, were revealed. New equipment for magnetohydrodynamic mixing (MHDM) of biosorbent with magnetic fluid in the combined electric and magnetically fields were developed for the first time. This installation allowed obtaining the magnetically operated biosorbent with stable magnetic properties and sorption capacity of not less than native yeast.

Development of methods and techniques for optimal design of unmanned aviation complex for industrial and ecological monitoring of the environment

The work is dedicated to the development and implementation of integrated design methodologies of individual elements of unmanned aircraft systems related to the problems of ensuring the necessary tactical and technical, performance, reliability characteristics, performance and unification into a single unified methodology and a system of making design decisions in the design process.

Development and implementation of series of precision wideband system oriented AC voltage multimeter

AC voltage measurement is the most common problem in electrical quantities measurement. The AC multimeters performance analysis shows that high accuracy is achieved in a narrow band of frequencies while there is a need to improve the accuracy not only in the sound but also in the short and in the ultrasonic frequency range. Therefore, element wise additive and multiplicative error correction technique to improve the accuracy was proposed. For this purpose, measurement channel is divided into functional blocks, each of which is complemented by a feedback circuit and aback up system.
