Hash Functions are Based on Three-Dimensional Stochastic Transformations 哈希函数是基于三维随机变换的
I. Chugunkov, M. A. Ivanov, Bogdana Kliuchnikova
The methods are based on injecting unpredictability into means and objects of protection are called stochastic methods of information security. The effective protection can be done only by using stochastic methods against an active opponent. The effectiveness of stochastic protection methods is defined by the quality of the used pseudo-random number generators and hash functions. The proposed hashing algorithm DOZENHASH is based on the using of 3D stochastic transformations of DOZEN family. The principal feature of the algorithm is that all input and output data blocks as well as intermediate results of calculations are represented as three-dimensional array of bytes with 4 bytes in each dimension. Thus, the resulting transformation has a high degree of parallelism at the level of elementary operations, in other words, it is focused on the implementation using heterogeneous supercomputer technologies.
这些方法是建立在将不可预测性注入保护手段和对象的基础上的,称为信息安全随机方法。有效的保护只能通过使用随机方法来对付一个活跃的对手。随机保护方法的有效性取决于所使用的伪随机数生成器和哈希函数的质量。提出的散列算法DOZENHASH是基于对DOZEN族的三维随机变换的利用。该算法的主要特点是将所有输入输出数据块以及计算的中间结果都表示为三维字节数组,每维4字节。因此,所得到的转换在基本操作级别上具有高度的并行性,换句话说,它侧重于使用异构超级计算机技术的实现。

Application of Template Matching for Optical Character Recognition 模板匹配在光学字符识别中的应用
D. Kalina, R. Golovanov
Optical character recognition (OCR) is one of the common research problems in the computer vision which is used for industrial processes automation. In this work the algorithm of OCR based on template matching recognition is presented. Algorithm is adopted for character recognition with consideration of low contrast conditions and texture on the background. The main feature of this method is interest area detection and adaptive binarization before pattern matching. The proposed method does not require large set of training samples, which may be critical in some applications. Also algorithm is easy to implement and has low complexity. Testing was conducted on custom dataset under the various conditions of illumination and pattern readability. The quality of the algorithm was estimated using standard binary classifier metrics and the distribution of correlation function in comparison with the template.

Development and Research of Circuit Solutions for the Creation of a Microelectronic Integrated Product of an Adaptive Control System for DC Motors 直流电机自适应控制系统微电子集成产品电路方案的开发与研究
Artem Nekrasov, Sh. B. Akhmedov, S. Shepelev, S. Gershunin
The one of the tremendous modern robotics problems is extremely short autonomous operation time of robots. This is due both to the various actuators high power consumption and the low batteries capacity. Among the possible solution the application of the principles of recovery stands out. According to that, the part of the energy can be returned to working system for reuse. For this, a device capable of controlling DC motors and storing energy under determined operating conditions is necessary. This article is devoted to the analysis of this issue, the development of the concept, the implementation of the prototype device and its individual elements and the perspective for translating the device into an integral form.

Optimization of Gas Engine Power Plant Operation Based on Study of Starting Conditions of a Powerful Motor Load 基于大功率电机负载起动条件研究的燃气发动机电厂运行优化
Artyom S. Petrikov, S. A. Kondratenko, A. N. Belyaev
The issues of transient stability and other disturbances caused by direct and smooth (reduced-current) starts of powerful induction motors in autonomous electric power system that supplies to oil pumping station and has generators and gas engine units, which are commensurate with the load, are considered. Analysis to determine maximum power of induction motor during direct starts is performed. It is noted that direct start-up of powerful induction motors is accompanied with large currents, which in turn cause significant decrease of voltages on load buses. The options based on step change of voltage and smooth start using polynomial functions of speed are proposed. Algorithm has been developed to optimize soft start of motor, based on minimum electromagnetic torque, taking into account values of current limits and starting time.

Calibration Module for Battery Management System of Medical Devices 医疗设备电池管理系统的校准模块
Anton E. Pavlov, D. Telyshev, I. Nesterenko
One of the main problems encountered in the development of a mobile medical device is the organization of power supply. Widely used rechargeable lithium-ion batteries have significant flaws, forcing to use a specialized battery management system that protects the battery from working outside its safe working area, ensuring maximum performance. A calibration circuit was developed for testing and adjusting a battery management system in process of fabrication to compensate the offset and gain of measurement circuits of the voltage, current and temperature. The technical solution of the calibrator was based on the development of three sections: the communication, control and temperature, the voltage supply and the current supply section. The voltage supply module was a multichannel precision voltage reference that simulated the voltage of a battery cells. The developed current supply section ensured the formation of electric current with an error of no more than one percent. Calibration of the battery management system allowed lithium-ion battery to operate in the range of permissible parameters, which was determinant in reducing the effect of short battery lifetime and eliminated possible dangerous situations.
在移动医疗设备的开发中遇到的主要问题之一是电源的组织。广泛使用的可充电锂离子电池存在重大缺陷,因此不得不使用专门的电池管理系统,以保护电池在其安全工作区域之外工作,以确保最佳性能。为了补偿电压、电流和温度测量电路的偏置和增益,设计了一种校准电路,用于在制造过程中对电池管理系统进行测试和调整。校准器的技术方案是基于三个部分的开发:通信、控制和温度,电压供电和电流供电部分。电压供应模块是模拟电池单元电压的多通道精密电压基准。开发的电流供应部分保证了电流的形成,误差不超过百分之一。电池管理系统的校准允许锂离子电池在允许的参数范围内工作,这对于减少电池寿命短的影响并消除可能的危险情况至关重要。
