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.

Theoretical substantiation of principles of construction of the diagnostic medical equipment and technology of its application

Електрохімічний сенсор парціального тиску кисню

A modern design concept of diagnostic medical equipment based on the focusing diffractive optical elements (DOEs). There were developed new methods for the determination of boundaries and the profile of the DOE for an arbitrarily given intensity, amplitude and phase of the optical field. A new method of determining the phase and energy transformations in the DOE in different diffraction orders. We propose a method of designing multifocal intraocular achromatic DOE bifocal type.

Heat transfer and aerodynamics of complicated profiled heat transfer surfaces

Експериментальні макети складнопрофільованих труб плоскоовальної форми з різним подовженням профілю

In tubular recuperative heat exchangers such as "gas-gas", "gas-liquid" are mainly used heat transfer of circular tubes. However, circular tubes, as part of the heat transfer surface, in terms of improving their heat and aerodynamic performances to date have exhausted themselves. Now, technically and economically the most accessible and reasonable by reducing weight and improving energy efficiency and resource saving heat exchange equipment is application in heat exchangers surfaces that have high heat and aerodynamic efficiency, low cost and ease of production.

Fundamentals of vector-controlled alternative current electromechanical systems with rolling pair kinematics

Дослідний зразок тягового електроприводу потужністю 200 кВт

The generalized mathematical models for the class of transport objects with vector-controlled AC motors are developed. A novel decomposition based control concept for electromechanical systems with rolling pair kinematic is presented. Control algorithms development procedure based on this concept provides a solution for the basic traction control tasks.

The research of the water dispersion parameters in impact with a hard dry and wetted surface was made. Noted best water spraying at surface with high roughness. This may be due to the difficulty of the air outlet from under flat (before impact) drops during impact. The share of dispersed liquid upon impact a teardrop-shaped expanding jet ( 40% of the water flow in the jet ) with wooden batten was investigated. Also was determined the radius of scattering droplets depending on the fall height and of the water flow consumption from the nozzle.

For the first time the scientific basis of a fundamentally new method of forming biocompatible (titanium alloy) coating of carbon nanotubes (CNT) in polycrystalline silicon oxide layers with nickel and iron catalytic centers are obtained by CVD for implants, dentures support-the driving apparatus of human and medical instruments were developed. For the first time a model of physical and chemical processes of the composite coatings formation under laser irradiation of CNT substrates with pre-coated with a layer of hydroxyapatite powder were proposed.

Research of ultra wideband impulse radio signals properties and development of self-organizing radio networks based on these signals and terminals for them.

Макети радіотерміналів, які можуть бути об’єднані в радіомережу із самоорганізацією

A new theoretical base and new methods of using ultra wide band radio signals in self-organized radio networks were created. The main idea of the self-organized networks is based on a fact that each terminal in the network acts not only as final transmitter and receiver of information but as a repeater – router for all subscribers in the network. Each terminal provides network parameters evaluation and optimizes information traffic control mechanisms.

Research and theoretical studies of new precision inertial navigation system in extreme conditions using neural networks

The actuality of solving the problem of fundamental researches of a new precision inertial navigation system (NS) in extreme conditions, which is the important constituent of the aviation gravimetrical system, is grounded. The classification of NS is resulted. The system of NS controlling has been improved.
