DC electric drives of rolling mills are the greatest electromechanical power consumers at iron and steel works. Energy indexes of these drives are far from the optimal ones. Most power losses are associated with consumption of reactive power caused by voltage phase control. Previous papers described the two-region control design based on rearranging reserve of the rectified EDV of the thyristor converter in steady-state and dynamic modes. Methods and systems of dependent control of excitation flow implementing that concept were proposed. A mathematical model of an electric drive of the wide-strip hot-rolling mill is required to study dynamic properties of this system. This paper depicts structures of control system models with coordinate switching controlled with the excitation circuit. Transient processes of the electric drive were investigated for a rolling cycle at different setting of EDV control circuits. Operational integrity and efficiency of the developed two-region speed control with switching units were proven. The results provide a rationale for introduction of the developed systems into the thyristor electric drives of rolling mills.

In this paper we describe the distributed storage structure with indexing techniques which can be applied in scientific Big Data centers. Basic principal of this project is distributed (N, K)-block storage. We develop the descent of LH∗RS especially for multidimensional data arrays using multiscaled representation of these arrays and efficient pre-processing algorithms. Dataset is decomposed into data blocks of several levels using the Wavelet transform. The required dataset of any requested scale and resolution is reconstructed online from the corresponding set of downloaded blocks on client's side. In order to accelerate data queries processing we can additionally use a pre-computed statistic results blocks and their hierarchical representation. The main advantage of this approach is that we can use these results together with original data or even separately to serve different data queries with both value and dimension subsetting conditions. This approach can reduce the resource costs of corresponding scientific problems.

Recognition of visual images is one of the most important components of the control systems, information processing systems and automated decision-making systems. In this paper the approach to develop control system of objection recognition based on convolutional neural network (CNN) is considered. The CNN is applied to the tasks of fruits detection and recognition through parameter optimization. The result of our test had accuracy in the classification close to 94% for the 30 classes of 971 images, indicating that the proposed system and methods could be used for vision subsystem based control applications.

Currently, parallel prefix adders (PPA) are considered effective combinational circuits for performing the binary addition of two multi-bit numbers. These adders are widely used in arithmetic-logic units, which are parts of modern processors, such as microprocessors, digital signal processors, etc. This paper deals with Kogge-Stone adder, which is one of the fastest PPA. When performing the schematic implementation, this adder has a large hardware complexity. Therefore, in this work for reducing its hardware complexity the scheme of modified PPA has been developed. The performance parameters considered for the comparative analysis of the presented adders are: the number of logic gates, Quine-complexity and maximum delay obtained when schematic modeling in CAD environment Quartus II based on FPGA Altera EP2C15AF484C6. As a result, when simulation of 32-bit adder, Kogge-Stone adder and modified PPA have similar maximum delay. However modified PPA has reduced hardware complexity by 22.5% compared to Kogge-Stone adder.

The increase of the ADC bit capacity is possible by involving the compression of the input signal according to the logarithmic law, while maintaining the phase of the signal. Theoretical calculations and computer simulation of the ADC coupled with the logarithmic amplifier demonstrate the significant improvement of the operating parameters of the circuit, the increase in dynamic range and decrease in the spread of the relative conversion error. The paper presents a logarithmic amplifier (LA) with 3.5 GHz bandwidth, 30 dB gain and 70 dB dynamic range. Current consumption is 90 mA and supply voltage 5 V. The mathematical description of the proposed inclusion method, as well as a graphical representation of the obtained parameters are presented. Methods for calculating the dynamic range are described and a comparison between two variants is made. Schematic modeling of the proposed method is carried out and the results are presented.
