  • Grid Fault Diagnosis Based on Information Entropy and Multi-source
           Information Fusion

    • Authors: Xin Zeng, Xingzhong Xiong, Zhongqiang Luo
      Pages: 143 - 148
      Abstract: In order to solve the problem of misjudgment caused by the traditional power grid fault diagnosis methods, a new fusion diagnosis method is proposed based on the theory of multi-source information fusion. In this method, the fault degree of the power element is deduced by using the Bayesian network. Then, the time-domain singular spectrum entropy, frequency-domain power spectrum entropy and wavelet packet energy spectrum entropy of the electrical signals of each circuit after the failure are extracted, and these three characteristic quantities are taken as the fault support degree of the power components. Finally, the four fault degrees are normalized and classified as four evidence bodies in the D-S evidence theory for multi-feature fusion, which reduces the uncertainty brought by a single feature body. Simulation results show that the proposed method can obtain more reliable diagnosis results compared with the traditional methods.

  • Miniaturized Wearable Fractal Patch Antenna for Body Area Network

    • Authors: Vikas Jain, Balwinder Singh Dhaliwal
      Pages: 149 - 154
      Abstract: This article presents the design of a miniaturized wearable patch antenna to be utilized for the body area network (BAN) applications. To reduce the size of the antenna a crown fractal geometry antenna design technique has been adopted, and which resulted in a size reduction of 26.85%. Further, the polyester cloth has been used as the substrate of the antenna to make the proposed antenna a flexible one, and suitable for wearable biomedical devices. The designed antenna functions for the 2.45 GHz ISM band and has the gain and bandwidth of 4.54 dB and 131 MHz respectively, covering the entire ISM band. The antenna characteristics like return loss (S11), directivity and radiation pattern have been simulated and analyzed. Specific absorption rate (SAR) and front to back ratio (FBR) of the proposed antenna at the human body tissue model (HBTM) in the planer and different bending conditions of the antenna have also simulated and analyzed, and the proposed antenna fulfils the desired design standards.

  • The stability interval of the set of linear system

    • Authors: Waldemar Wójcik, Talgat Mazakov, Sholpan Jomartova, Gulzat Ziyatbekova, Nurgul Karymsakova, Aisulu Tursynbai
      Pages: 155 - 161
      Abstract: The article considers the problem of stability of interval-defined linear systems based on the Hurwitz and Lienard-Shipar interval criteria. Krylov, Leverier, and Leverier-Danilevsky algorithms are implemented for automated construction and analysis of the interval characteristic polynomial. The interval mathematics library was used while developing the software. The stability of the dynamic system described by linear ordinary differential equations is determined and based on the properties of the eigenvalues of the interval characteristic polynomial. On the basis of numerical calculations, the authors compare several methods of constructing the characteristic polynomial. The developed software that implements the introduced interval arithmetic operations can be used in the study of dynamic properties of automatic control systems, energy, economic and other non-linear systems.

  • Efficient Wireless Sensor Network for Radiation Detection in Nuclear Sites

    • Authors: Sherief Hashima, Imbaby Ismail Mahmoud
      Pages: 175 - 180
      Abstract: Due to the severe damages of nuclear accidents, there is still an urgent need to develop efficient radiation detection wireless sensor networks (RDWSNs) that precisely monitor irregular radioactivity. It should take actions that mitigate the severe costs of accidental radiation leakage, especially around nuclear sites that are the main sources of electric power and a lot of health and industrial applications. Recently, leveraging machine learning (ML) algorithms to RDWSNs is a promising solution due to its several pros, such as online learning and self-decision making. This paper addresses a novel and efficient ML-based RDWSNs that utilizes millimeter waves (mmWaves) to cope with future networks requirements. Specifically, we leverage an online learning multi-armed bandit (MAB) algorithm called Thomson sampling (TS) to a 5G enabled RDWSN to efficiently forward the measured radiation levels of the distributed radiation sensors within the monitoring area. The utilized sensor nodes are lightweight smart radiation sensors that are mounted on mobile devices and measure radiations using software applications installed in these mobiles. Moreover, a battery aware TS (BA-TS) algorithm is proposed to forward the sensed radiation levels to fusion decision center efficiently. BA-TS reflects the remaining battery of each mobile device to prolong the network lifetime. Simulation results ensure the efficiency of the proposed BA-TS algorithm regards throughput and network lifetime over TS and exhaustive search method.

  • Cycles in Bayesian Networks

    • Authors: Alexander Litvinenko, Natalya Litvinenko, Orken Mamyrbayev, Waldemar Wójcik, Dusmat Zhamangarin
      Pages: 181 - 186
      Abstract: The article is devoted to some critical problems of using Bayesian networks for solving practical problems, in which graph models contain directed cycles. The strict requirement of the acyclicity of the directed graph representing the Bayesian network does not allow to efficiently solve most of the problems that contain directed cycles. The modern theory of Bayesian networks prohibits the use of directed cycles. The requirement of acyclicity of the graph can significantly simplify the general theory of Bayesian networks, significantly simplify the development of algorithms and their implementation in program code for calculations in Bayesian networks.

  • Design of wearable EEG device for seizures early detection

    • Authors: Viktoriia Gaidar, Oleksandr Sudakov
      Pages: 187 - 192
      Abstract: This paper presents the design of a wearable electroencephalography device and signal processing algorithm for early detection and forecasting of the epileptiform activity. The availability of the examination of functional brain activity for a prolonged period, outside of the hospital facilities, can provide new advantages in early diagnosis and intervention systems. In this study, the low-cost five-channel device is presented. The system consists of two main parts: the data acquisition and transmission units and processing algorithms. In order to create the robust epileptiform pattern recognition approach the application of statistical sampling and signal processing techniques are performed. The discrete wavelet and Hilbert-Huang transforms with principal component analysis are used in order to extract and select a low-dimension feature vector.

  • Arithmetic using compression on elliptic curves in Huff's form and
           its applications

    • Authors: Robert Dryło, Tomasz Kijko, Michał Jakub Wroński
      Pages: 193 - 200
      Abstract: In this paper for elliptic curves provided by Huff's equation $H_{a,b}: ax(y^2-1) = by(x^2-1)$ and general Huff's equation $G_{\overline{a},\overline{b}}\ :\ {\overline{x}}(\overline{a}{\overline{y}}^2-1)={\overline{y}}(\overline{b}{\overline{x}}^2-1)$ and degree 2 compression function $f(x,y) = xy$ on these curves, herein we provide formulas for doubling and differential addition after compression, which for Huff's curves are as efficient as Montgomery's formulas for Montgomery's curves $By^2 = x^3 + Ax^2 + x$. For these curves we also provided point recovery formulas after compression, which for
      a point $P$ on these curves allows to compute $[n]f(P)$ after compression using the Montgomery ladder algorithm, and then recover $[n]P$. Using formulas of Moody and Shumow for computing odd degree isogenies on general Huff's curves, we have also provide formulas for computing odd degree isogenies after compression for these curves.
      Moreover, it is shown herein how to apply obtained formulas using compression to the ECM algorithm. In the appendix, we present examples of Huff's curves convenient for the isogeny-based cryptography, where compression can be used.

  • Cryptographically Strong Elliptic Curves of Prime Order

    • Authors: Janusz Szmidt, Rafał Gliwa, Marcin Barański
      Pages: 207 - 212
      Abstract: The purpose of this paper is to generate cryptographically strong elliptic curves over prime fields Fp, where p is a Mersenne prime, one of the special primes or a random prime. We search for elliptic curves which orders are also prime numbers. The cryptographically strong elliptic curves are those for which the discrete logarithm problem is computationally hard. The required mathematical conditions are formulated in terms of parameters characterizing the elliptic curves.We present an algorithm to generate such curves. Examples of elliptic curves of prime order are generated with Magma.

  • Crisis remote education from the perspective of one-year experience of
           academic teachers

    • Authors: Milosz W Romaniuk, Joanna Teresa Łukasiewicz-Wieleba
      Pages: 213 - 219
      Abstract: The article presents the results of the questionnaire research carried out after the first and repeated after the second semester of crisis distance education, conducted at the Academy of Special Education. Academic lecturers participating in the study indicate a significant decrease in the level of commitment, activity, the regularity of work and the quality of performing tasks presented by students. Lecturers benefit from training and technical support organized by the university. They feel an acute inability to contact students personally, but appreciate the time savings and no need to travel to work. The respondents point to the problem of controlling student integrity during remote examinations. Growing experience in remote education results in higher IT competences and conviction to this type of teaching.

      Pages: 221 - 227
      Abstract: The article presents the results of the questionnaire research carried out after the first and repeated after the second semester of crisis remote education, conducted at The Maria Grzegorzewska University. Students participating in the study indicate a significant increase in their IT competences and the level of remote education. They declare a similar, high level of commitment and independence during classes. They indicate that commitment, activity, contact with the lecturers, regularity and quality of work, as well as the adequacy of the grades given are better during traditional education, although their timeliness is higher during distance education. The computer equipment of students and the way of accessing the Internet have not changed significantly. 20% of respondents admitted to using unauthorized assistance during exams. In the statements of students, on the one hand, there is a desire to return to social contacts and traditional classes, and on the other hand, a desire to maintain remote education, associated with the comfort of home-based learning and independence.

  • Basic Logic Gates in Two Dimensional Photonic Crystals for All Optical
           Device Design

    • Authors: Mahesh V Sonth, G. Srikanth, Pankaj Agrawal, B. Premalatha
      Pages: 247 - 253
      Abstract: The research carried out in the field of optics and photonics with an idea to design and develop the all optical logic devices in the fascinating material known as photonic crystals (PhCs). The structural investigation reveals that the two dimensional (2-D) PhCs is more suitable for fabrication of optoelectronic components. In this article we have designed basic logic gates in 2-D PhCs as they are the building blocks for the construction of optical devices and in these, refractive index is periodically modulated with the wavelength. The understanding of light behaviour in complex PhCs helps in creating photonic band gap (PBG) that can prevent light of certain wavelength propagating in crystal lattice structure. For the selected geometry structure, three PBG bands will exists out of which two of them are transverse electric (TE) and one is transverse magnetic (TM) mode. The PBG bands in the TE mode ranges from 0.31(a/λ) to 0.46(a/λ) , 0.61(a/λ) to 0.63(a/λ) and TM mode ranges from 0.86(a/λ) to 0.93(a/λ). The free space wavelength of 1550 nm is set for the finite difference time domain (FDTD) simulation of the structure. The response time and computational overhead required for the proposed OR gate is 0.128ps and 4.4MB is obtained. Also we calculated the extinction ratio for AND gate and NOT gate as 6.19 dB and 10.21 dB respectively.

  • Impact of Dimming LED Street Luminaires on Power Quality

    • Authors: Tomasz Lerch, Michał Rad, Igor Wojnicki
      Pages: 255 - 260
      Abstract: More and more street lighting deployments use LED technology as a light source. Unfortunately, the new technology also brings some challenges with it that remain unnoticed until installed at scale. This article presents issues related to capacitive reactive power consumed by LED luminaires. The problem is even more profound if the luminaire is dimmed, because it consumes capacitive reactive power, which is very undesirable in the power system. Countermeasures in terms of reactive power compensation for a luminaire working with variable power and their effects are also presented. The article also contains the results of the harmonic analysis of the LED luminaires current for full power and dimmed operation.

  • Development of data-mining technique for seismic vulnerability assessment

    • Authors: Waldemar Wójcik, Markhaba Karmenova, Saule Smailova, Aizhan Tlebaldinova, Alisher Belbeubaev
      Pages: 261 - 266
      Abstract: Assessment of seismic vulnerability of urban
      infrastructure is an actual problem, since the damage caused by
      earthquakes is quite significant. Despite the complexity of such
      tasks, today’s machine learning methods allow the use of “fast”
      methods for assessing seismic vulnerability. The article proposes
      a methodology for assessing the characteristics of typical urban
      objects that affect their seismic resistance; using classification and
      clustering methods. For the analysis, we use kmeans and hkmeans
      clustering methods, where the Euclidean distance is used as a
      measure of proximity. The optimal number of clusters is
      determined using the Elbow method. A decision-making model on
      the seismic resistance of an urban object is presented, also the
      most important variables that have the greatest impact on the
      seismic resistance of an urban object are identified. The study
      shows that the results of clustering coincide with expert estimates,
      and the characteristic of typical urban objects can be determined
      as a result of data modeling using clustering algorithms.

      Pages: 267 - 275
      Abstract: Cyber-attacks are increasing day by day. The generation of data by the population of the world is immensely escalated. The advancements in technology, are intern leading to more chances of vulnerabilities to individual’s personal data. Across the world it became a very big challenge to bring down the threats to data security. These threats are not only targeting the user data and also destroying the whole network infrastructure in the local or global level, the attacks could be hardware or software. Central objective of this paper is to design an intrusion detection system using ensemble learning specifically Decision Trees with distinctive feature selection univariate ANOVA-F test. Decision Trees has been the most popular among ensemble learning methods and it also outperforms among the other classification algorithm in various aspects. With the essence of different feature selection techniques, the performance found to be increased more, and the detection outcome will be less prone to false classification. Analysis of Variance (ANOVA) with F-statistics computations could be a reasonable criterion to choose distinctives features in the given network traffic data. The mentioned technique is applied and tested on NSL KDD network dataset. Various performance measures like accuracy, precision, F-score and Cross Validation curve have drawn to justify the ability of the method.

  • An Enhanced IEEE1588 Clock Synchronization for Link Delays Based on a
           System-on-Chip Platform

    • Authors: Xiaohan Wei, Xingzhong Xiong, Zhongqiang Luo, Jianwu Wang, Kaixing Cheng
      Pages: 289 - 294
      Abstract: The clock synchronization is considered as a key technology in the time-sensitive networking (TSN) of 5G fronthaul. This paper proposes a clock synchronization enhancement method to optimize the link delays, in order to improve synchronization accuracy. First, all the synchronization dates are filtered twice to get the good calculation results in the processor, and then FPGA adjust the timer on the slave side to complete clock synchronization. This method is implemented by Xilinx Zynq UltraScale+ MPSoC (multiprocessor system-on-chip), using FPGA+ARM software and hardware co-design platform. The master and slave output Pulse Per-Second (PPS) signals. The synchronization accuracy was evaluated by measuring the time offset between PPS signals. Contraposing the TSN, this paper compares the performance of the proposed scheme with some previous methods to show the efficacy of the proposed work. The results show that the slave clock of proposed method is synchronized with the master clock, leading to better robustness and significant improvement in accuracy, with time offset within the range of 40 nanoseconds. This method can be applied to the time synchronization of the 5G open fronthaul network and meets some special service needs in 5G communication.

  • Centralized Spectrum Sharing and Coordination Between Terrestrial and
           Aerial Base Stations of 3GPP-Based 5G Networks

    • Authors: Kamil Bechta
      Pages: 301 - 308
      Abstract: The objective of this paper is to estimate performance of a new approach for spectrum sharing and coordination between terrestrial base stations (BS) and On-board radio access nodes (UxNB) carried by Unmanned Aerial Vehicles (UAV). This approach employs an artificial intelligence (AI) based algorithm implemented in centralized controller. According to the assessment based on the latest specifications of 3rd Generation Partnership Project (3GPP) the newly defined Unmanned Aerial System Traffic Management (UTM) is feasible to implement and utilize an algorithm for dynamic and efficient distribution of available radio resources between all radio nodes involved in process of optimization. An example of proprietary algorithm has been described, which is based on the principles of Kohonen neural networks. The algorithm has been used in simulation scenario to illustrate the performance of novel approach of centralized radio channels allocation between terrestrial BSs and UxNBs deployed in 3GPP-defined rural macro (RMa) environment. Simulation results indicate that at least 85% of simulated downlink (DL) transmissions are gaining additional channel bandwidth if presented algorithm is used for spectrum distribution between terrestrial BSs and UxNBs instead of baseline soft frequency re-use (SFR) approach.
