N. Sitkov, T. Zimina, A. Soloviev
A miniature impedimetric sensor element (I SE), integratable into a laboratory-on-a-chip for testing the antibiotic resistance of microorganisms is described. The topology, design and manufacturing technology of ISE based on interdigital electrodes are described. With the help of a sample of chips, measurements were made on the evaluation of antibiotic resistance (ABR) of microorganisms, using E. coli M-17 as a model, under the influence of a number of antibiotics. The possibility of using the developed sensor element for ABR estimation at the exposure time of 1 to 2 hours is shown experimentally. The concentration sensitivity limit of the sensor element was determined. Frequency dependences of the electrical impedance for E. coli M-17 with various antimicrobial agents were obtained. The susceptibility of investigated bacterial type to ceftazidime and ceftriaxone as well as a lack of susceptibility to benzylpenicillin has been experimentally confirmed. A numerical parameter is proposed for assessing the degree of antibiotic resistance of microorganism.

Study and analysis of power quality situation in electrical power network. Case study: Lattakia-Syria 电网电能质量现状的研究与分析。案例研究:拉塔基亚-叙利亚
R. Nasyrov, R. Aljendy, T. Kherbek
Power Quality (PQ) is a broad term used to describe the electrical power system's performance and efficiency. The impact of PQ disturbances on the industries and individual facilities is manifested as reducing uptime of plant equipment, losing production, lost data, and other costly ramifications. In this regard, the PQ problems have become a major concern for modern industries with nonlinear loads in electrical power system. This paper presents the measurements and analysis of the (66/20 kV) distribution network in Syria (city Lattakia), which has important loads with high power quality disturbances. PQ problems, especially harmonics and voltage fluctuations, have been analyzed in this work. Moreover, suitable solutions to mitigate these problems have been discussed. The power distribution system has been modeled using Matlab /Simulink (2016a).

Investigation of radiation characteristics of 4-port magnetic antenna with heterogenic conformai core on large aircraft 大型飞机上四端口异质共形磁芯磁天线辐射特性研究
A. Semenikhin, A. I. Chernokolpakov
In the paper, investigation of a conformai heterogeneous magnetic antenna (MA) for radio communication on high frequencies is presented. The antenna is constructed to be mounted on moving platforms, which are designed using stealth technologies. Loop 4-port magnetic antenna with lengthwise heterogeneous (piecewise uniform) ferrite core is studied with the finite elements method. The antenna is mounted conformally on two carrier platforms, i.e. flat part of the carrier coating and fuselage of a large aircraft (LA) without fin. The influence of the form of the heterogeneous core and the phase feed modes of the ports of the magnetic antenna on the radiation efficiency and the gain of the “ MA — carrier” system in the frequency band 2–30 MHz is studied. Radiation pattern and expected radiation efficiency of the “MA — carrier” system are shown. It is shown, that usage of the heterogeneous magnetic antenna increases the radiation efficiency of the “MA — carrier” system in comparison with a homogeneous magnetic antenna.

Integral active element for transmitting optical modules 用于传输光模块的整体有源元件
A. V. Dem’yanenko
With the development of injection semiconductor lasers (ISL) that generates electromagnetic energy in the optical range, a possibility of miniaturization of data transmission and processing systems operating at frequencies of 1014 Hz and higher has emerged. The current state of solid-state laser technology makes it possible to talk about modulation frequencies up to 30 GHz. It gives the possibility of development of optical microwave modulators, and providing radio transmitting devices of the optical range with a basic element base. In the present work, a prototype of a new optoelectronic device is proposed, that combines two generator elements in a single package, providing simultaneous generation of a carrier and modulating oscillations. In such a device, microwave modulation of the ISL occurs based on internal physical mechanisms, as a result of coupling between the generating crystals. The design of a multifunctional optoelectronic device and its operating principle are discussed.

Fast and accurate back propagation method for reliability evaluation of logic circuits 逻辑电路可靠性评估的快速准确反向传播方法
A. Stempkovskiy, D. Telpukhov, V. Nadolenko
Paper presents an enhanced method for computation of logic gates' observabilities at circuit outputs, which are used as technology-independent metric for circuit reliability. When bit-parallel simulation is being applied, circuit's ability to propagate errors from each certain gate to its outputs is presented as set of ODC (observability-don't-care) masks. Proposed method for calculating ODCs is based on both direct error simulation and back propagation, being accurate as former in presence of reconvergent branches and almost as fast as latter in their absence. In addition, reconvergence handling is further improved by implementation of reduced circuit structure. Proposed algorithm has been applied to ISCAS85 benchmark circuits and then compared to error simulation and back propagation algorithms. Thus it is proven to provide accurate ODCs for given sequence of input sets being considerably faster than complete simulation. Results of computational experiments are also present in paper.
本文提出了一种计算电路输出处逻辑门可观测性的改进方法,并将其作为电路可靠性的技术无关度量。当应用位并行仿真时,电路将错误从每个特定门传播到其输出的能力表现为一组ODC(可观察性-不在乎)掩码。本文提出的odc计算方法基于直接误差模拟和反向传播,在存在再收敛分支时与前者一样准确,而在不存在再收敛分支时几乎与后者一样快。此外,通过简化电路结构的实现,进一步改善了再收敛处理。将该算法应用于ISCAS85基准电路,并与误差仿真和反向传播算法进行了比较。因此,它被证明为给定的输入集序列提供准确的odc,比完全模拟要快得多。文中还给出了计算实验结果。

Method of the accelerated verification of ECC (Error — Correcting codes) codecs by means of Simulink/Matlab packet 利用Simulink/Matlab包加速校验ECC(纠错码)编解码器的方法
A. Belyaev, P. Poperechny, I. Poperechnaya
Nowadays there are a lot of software packets for simulation, modeling, debugging of hardware module description. However there are some issues related with functional testing of the algebraic blocks and algorithms. In case of comparison the designed algorithm with reference one we need a wide library of well-known proven models. MatLab packet has the large library of many famous algorithm models rather than other simulators. Another approach is to design own testbenches with proven software algorithm implementation, but sometimes it can be very difficult. This article describes a method of statistic analysis during the error-correcting codes decoding by the codecs with designed hardware by means Simulink/Matlab library elements and its interaction with SAD (System of automatic design) for hardware simulation. For accelerating the offered approach it is supposed the cross-platform modeling using evaluation board with FPGA. This method decreases in order statistic analysis time of error-correcting capability compared with this analysis by means of PC only. Also the model of non-binary symbol noise for Reed-Solomon codecs is proposed.
目前有大量的软件包对硬件模块的仿真、建模、调试进行描述。然而,代数块和算法的功能测试存在一些问题。为了将所设计的算法与参考算法进行比较,我们需要一个广泛的已知已证明的模型库。与其他模拟器相比,MatLab包具有许多著名算法模型的大型库。另一种方法是使用经过验证的软件算法实现设计自己的测试平台,但有时这可能非常困难。本文介绍了一种利用Simulink/Matlab库元素对设计好的硬件编解码器对纠错码进行译码时的统计分析方法及其与自动设计系统(System of automatic design)的交互进行硬件仿真的方法。为了加速所提出的方法,提出了基于FPGA的评估板跨平台建模方法。与仅使用PC机的分析方法相比,该方法减少了纠错能力的阶统计分析时间。提出了Reed-Solomon编解码器的非二进制符号噪声模型。
