Analysis of possibilities to use neural network for remote control of electronic devices

(Technology audit and production reserves, 2018) Галкін, П. В.; Голіков, М. О.

The object of research in the work is the systems of remote control of electronic devices. There are wired and wireless means of implementing a remote communication channel between the slave and control devices. Analysis of existing means of creating a communication channel, found a low value of the ratio of system flexibility and data transfer rate within the created network. One of the reasons for the low ratio is the use of modules as part of a system with a high minimum operating time. Such modules are modules for filtering and decoding the received signal at the receiver side, encoding and modulation at the transmitter side. Replacing these modules with one with a significantly lower time spent will significantly improve the value of the ratio of system flexibility and data transfer rate. The ability to create a module that will have the necessary properties of time spent on work, provides a neural network. The model of a remote control system obtained during the study has several advantages, in particular, the presence of a neural network, makes it possible to reduce the time spent and to improve the accuracy of the system during the entire system operation time. This is achieved thanks to the ability of the neural network to self-learning without human intervention and its ability to analyze any input signals with different background noise values. These properties allow the replacement of elements that do not allow to increase the rate of exchange for elements of the neural network that will perform the same functions with greater speed, reliability and accuracy. The data obtained during the work proves the expediency of integrating the elements of the neural network into the remote control systems of electronic devices. Also, possible places for the integration of a neural network into the remote control system of electronic equipment have been proposed, which will improve the stability, accuracy, speed of the system.

Coaxial aperture sensor for assessing the state of biologica objects

(2018) Panchenko, A. Yu.; Slipchenko, N. I.; Zaichenko, O. B.; Bondarenko, I. N.

Water is the main substance that makes living organisms. The state of any bioobject is characterized by the total amount of water in it and its distribution. In biological matter, water can be in two states, in the form of free water and water, associated with its macromolecules. The distribution of free water and water associated with molecules of biological matter determines its state. Therefore, the task of rapid assessment of water distribution is topical. The water molecule has a low mass and in the free state the molecules have a high relaxation frequency, which lies in the microwave range. The dipole moment of water has a high value. Therefore, at frequencies below the relaxation frequency, water has a high value of the dielectric constant. In the bound state, its electrophysical properties of water depend on the properties of the macromolecule in which it is embedded. Therefore, microwave methods and electrodynamic measurement sensors are effective means of operative measurements. They have a high speed, simple measurement procedure, do not require special preparation of samples, they allow performing non-destructive testing. Therefore, under certain conditions, they have advantages over other methods. However, the problems of using electrodynamic methods are caused by the indirect nature of the data obtained and the rather complicated process of determining the transfer function of the microwave sensor. The report presents a scheme of the microwave sensor, in which the generatrix coincides with the coordinate surfaces. For such a scheme, you can create a rigorous analytical model. Solving the task of describing fields in the working area of such a sensor allows determining the transfer function of the sensor. The presented scheme allows a principled possibility of further development. For example, in the presence of a mathematical model of changes in the properties of a bioobject under external influence. This will allow a numerical evaluation of the sensor parameters at the theoretical preparation stage. Such an approach will significantly reduce time costs and reduce the cost of design, prototyping and experimental development of specific designs.
