A Security Key Recovery System with Channel Quality Awareness for Smart Grid Applications
Authors: Huadpaknam Prachya , Pirak Chaiyod , Mathar Rudolf
Published: April 2020

In this paper, a security key recovery system with channel quality awareness (SKRS-CQA) for smart grid applications has been proposed. Firstly, the proper key recovery agents (KRAs) are determined based on the signal-to-noise ratio (SNR) outage probability. The result of such selection includes the number and the index of selected KRAs. Then, the session key (KS) of a Smart Meter Unit (SMU) will be divided into many different pieces according to the proposed key partitioning algorithm and stored in the selected KRAs for the future key recovery if the data concentrator unit (DCU) has lost the key in unexpected events. The outage probability of SNR, the probability of KRA failure, and the probability of key compromising are also investigated. In addition, a 128-bit AES-GCM encryption algorithm is used in each KRA for authentication and identification mechanisms based on a DLMS/COSEM protocol. As shown in the system performance analysis, the system reliability, the system availability, and the data confidentiality have been improved compared with the conventional scheme. Moreover, a cooperative communication network with an amplify-and-forward relaying protocol and an optimal power allocation has been employed for improving the system reliability. From computer simulation results, it showed that the reliability of the proposed system with a cooperative scheme has been improved significantly.
Enhancing Process Visibility of the Supply Chain ‘Data Pipeline’
Authors: Pruksasri Potchara , Berg Jan van den , Hofman Wout , Tan Yao-Hua
Published: April 2020

Although business process visibility is considered to be increasingly important for international trade, the visibility of existing supply chains is currently still ambiguous. Information deficiencies such as incorrectness or inconsistency of data are major determinants that decrease clarity. The Data Pipeline principle has been proposed to overcome the data quality shortcomings, enhance the visibility, and improve performance of the supply chain. In a first elaboration, the Data Pipeline model named the Distributed Trust Backbone (DTB) was designed and implemented in three different countries. In order to discover the effectiveness and feasibility of the model, the visualization of the Data Pipeline’s process flow is urgently required in terms of both real-time detection of system failures and process flow representations. However, there is no process visualization feature available for the Data Pipeline. This challenge is taken up in this paper. We propose a Data Pipeline monitoring system and describe the results of performed simulation tests based on a case study of the international trade lane between Southeast Asia and Europe.
Extended Hierarchical Extreme Learning Machine with Multilayer Perceptron
Authors: Phumrattanaprapin Khanittha , Horata Punyaphol
Published: April 2020

The Deep Learning approach provides a high performance of classification, especially when invoking image classification problems. However, a shortcoming of the traditional Deep Learning method is the large time scale of training. The hierarchical extreme learning machine (H-ELM) framework was based on the hierarchical learning architecture of multilayer perceptron to address the problem. H-ELM is composed of two parts; the first entails unsupervised multilayer encoding, and the second is the supervised feature classification. H-ELM can give a higher accuracy rate than the traditional ELM. However, there still remains room to enhance its classification performance. This paper therefore proposes a new method termed the extending hierarchical extreme learning machine (EH-ELM), which extends the number of layers in the supervised portion of the H-ELM from a single layer to multiple layers. To evaluate the performance of the EH-ELM, the various classification datasets were studied and compared with the H-ELM and the multilayer ELM, as well as various state-of-the-art such deep architecture methods. The experimental results show that the EH-ELM improved the accuracy rates over most other methods.
Quantification of Valve Stiction using Particle Swarm Optimisation with Linear Decrease Inertia Weight
Authors: Aksornsri Pongsurachat , Wongsa Sarawan
Published: April 2020

Valve stiction is one of the most common problems on industrial process control loops. The detection and quantification of valve stiction in control loops is therefore important to ensure the high quality of the products and maintain the reliable performance of control loops. This paper presents an algorithm for quantifying valve stiction in control loop based on linear decrease inertia weight particle swarm optimization to obtain more accurate estimates of stiction parameters. The amount of stiction present in the valve is estimated by identifying parameters of Kano model which is a two-parameter data-driven stiction modelling based on the parallelogram of MVPV phase plot. Simulation results have demonstrated the efficacy of this algorithm in valve stiction quantification and also its robustness to oscillations due to inappropriate controller tuning and external disturbances. Results are confirmed by application to real process industrial data.

Authors: Grout Ian A. , Zaidi Muhaned , Sterckx Karel L. , Bin A'ain Abu Khari
Published: April 2020

In this paper, the design of a programmable mixed-signal electronic circuit to control the light output of a red-green-blue (RGB) light emitting diode (LED) to be used in an optical fiber sensor system is presented and discussed. The LED is to be used as a light transmitter (light source) within the sensor system. The output of each LED color is to be independently controlled using either a d.c. current or a pulse width modulation (PWM) encoded current. The idea for, and architecture of, the mixed-signal electronic circuit design is considered as both a discrete implementation using off-the-shelf components and the concept for an application specific integrated circuit (ASIC) solution using a 0.35 µm complementary metal oxide semiconductor (CMOS) fabrication process. In this paper, the design operation principles, circuit architecture, simulation results and hardware requirements for this LED driver circuit are considered.
New Cascaded Multilevel Inverter by Using Capacitor Based Basic Units with the Capability of Charge Balance Control Method
Authors: Laali Sara , Babaei Ebrahim
Published: April 2020

In this paper, two new cascaded multilevel inverters based on new capacitor basic unit are proposed. In the proposed topologies, the same numbers of dc voltage source and capacitor are used that lead to decrease the number of required insulated dc voltage sources. In order to generate all positive and negative voltage levels (even and odd) at the output three different algorithms to determine the magnitude of voltage sources are proposed. Minimum number of used power electronic devices and lower amount of blocked voltage that is made by power switches are two main advantages of the proposed topologies. These features lead to decrease the installation space and total cost of the inverter. These are obtained by comparing the proposed topologies with several capacitor based cascaded multilevel inverters. In addition, in order to balance the used capacitors’ voltage, a new charge balance control method is proposed. Finally, the correct performance of the proposed cascaded inverter is reconfirmed through experimental and simulation results on a five-level proposed inverter in EMTDC/PSCAD software program.
Kernel Principal Component Analysis Allowing Sparse Representation and Sample Selection
Authors: Wang Duo , Tanaka Toshihisa
Published: April 2020

Kernel principal component analysis (KPCA) is a kernelized version of principal component analysis (PCA). A kernel principal component is a superposition of kernel functions. Due to the number of kernel functions equals the number of samples, each component is not a sparse representation. Our purpose is to sparsify coefficients expressing in linear combination of kernel functions, two types of sparse kernel principal component are proposed in this paper. The method for solving sparse problem comprises two steps: (a) we start with the Pythagorean theorem and derive an explicit regression expression of KPCA and (b) two types of regularization $l_1$-norm or $l_{2,1}$-norm are added into the regression expression in order to obtain two different sparsity form, respectively. As the proposed objective function is different from elastic net-based sparse PCA (SPCA), the SPCA method cannot be directly applied to the proposed cost function. We show that the sparse representations are obtained in its iterative optimization by conducting an alternating direction method of multipliers. Experiments on toy examples and real data confirm the performance and effectiveness of the proposed method.
Segmenting Snow Scene from CCTV using Deep Learning Approach
Authors: Borwarnginn Punyanuch , Kusakunniran Worapan , Pooyoi Parintorn , Haga Jason H.
Published: April 2020

Recently, data from many sensors has been used in a disaster monitoring of things, such as river wa- ter levels, rainfall levels, and snowfall levels. These types of numeric data can be straightforwardly used in a further analysis. In contrast, data from CCTV cameras (i.e. images and/or videos) cannot be easily interpreted for users in an automatic way. In a tra- ditional way, it is only provided to users for a visual- ization without any meaningful interpretation. Users must rely on their own expertise and experience to interpret such visual information. Thus, this paper proposes the CNN-based method to automatically in- terpret images captured from CCTV cameras, by us- ing snow scene segmentation as a case example. The CNN models are trained to work on 3 classes: snow, non-snow and non-ground. The non-ground class is explicitly learned, in order to avoid a confusion of the models in differentiating snow pixels from non- ground pixels, e.g. sky regions. The VGG-19 with pre-trained weights is retrained using manually la- beled snow, non-snow and non-ground samples. The learned models achieve up to 85% sensitivity and 97% specificity of the snow area segmentation.
An Extensive Tensor Algebraic Model of Transformer
Authors: Banchuin Rawid , Chaisrichaoren Roungsan
Published: April 2020

An extensive s-domain tensor algebraic model of the transformer has been proposed. Unlike the traditional matrix-vector approach which relies on the conventional linear algebra, this model which in turn assumes the multilinear algebra that is of higher dimension thus more generic, is applicable to those recently often cited transformers which often employ the unconventional characteristics i.e. frequency variant parameters, time variant parameters and fractional impedance. The examples of such transformers are the on-chip monolithic transformer, the dynamic transformers and the fractional mutual inductance etc. The imperfect coupling has been considered and multiple winding transformer has also been assumed. The applications of the proposed model to the chosen recent transformers with those unconventional characteristics have been presented. The effects of failure of Kron’s postulate on power invariant and validity of duality invariant which are worthy of mentioned issues, have also been discussed. The proposed extensive model is more inclusive and up to date than the matrix-vector based model and those foregoing tensor algebraic models albeit it is more complicated.
Test Input Data Generation for Choiceless Program Nets
Authors: Biao Wu , Ge Qi-Wei
Published: April 2020

Software testing is an important problem in designing a large software system and this problem is difficult to be solved due to its computational complexity. We try to use program nets to approach this problem and have proposed algorithms to divide a whole program net into subnets that can structurally cover the original one based on divide-and-conquer method. This paper aims to solve the remaining task of our approach, that is how to find test input data for each subnet to be called choiceless program net. Firstly, definitions of program nets are extended and the properties of choiceless program nets are analysed. Secondly, polynomial algorithms are proposed to get all constraint conditions of any given choiceless program nets. Finally, a method to generate test input data under the obtained constraint conditions is proposed by adopting an SMT (Satisfiability Modulo Theories) solver, $Z3$ prover, and also an example is given to show the usefulness of our method.

Published: April 2020

The article deals with the development of human society under the conditions of change of the final technological pattern existing before the 4th industrial revolution. The change is associated with the development of information and communication technologies (ICT) as one of the catalysts of sustainable progress in the development of social and industrial relations in the modern society. It is stated that progress in the field of industrial relations and technologies developing conformity with the exponential law. At the same time, according to the law, the so-called point of technological singularity appears on the time scale of the development when the development path of what is referred to as machine intelligence becomes unpredictable. Various behavior scenarios and the use of artificial intelligence (AI), including its machine learning tools employed for the adverse purposes of enslaving human society, are considered. However, recent studies of mathematicians prove that the possibilities of AI are not unlimited. Like the human mind, AI is limited by the paradoxes of the theory of sets. In this regard, in the development and application of ICT, it is necessary to implement the integrated level of ICT fusion with the evolutionary development of personality and society that would not lead to the suppression of the human thought process by the services of technocratic means.

На протяжении последних двух десятилетий Китай постепенно, но планомерно открывает свой национальный рынок капитала для иностранных инвесторов. К текущему моменту через так называемые мосты между биржами Шанхая, Шэньчжэня и Гонконга иностранным и китайским инвесторам доступно свыше 2 000 акций для взаимной торговли.

For more than the past two decades China has been gradually but systematically opening up its national capital market to foreign investors. Over 2,000 shares for mutual trade have been made available by now to foreign and Chinese investors via the so-called Connects between the exchanges in Shanghai, Shenzhen and Hong Kong. The Chinese stock market today is one of the youngest (the Shanghai Stock Exchange, for example, turns 29 years old this year) and at the same time the most attractive in terms of the profitability/risk ratio developed countries show no tangible dynamics of economic growth, nor yields on their securities, while India and Vietnam, which are comparable in terms of economic growth rates to Chinese ones, cannot offer similar market volumes. For example, the United States has long sought the Chinese capital market to be opened, especially after China had entered the WTO. Russian investors have also been interested in the securities of Chinese companies for a long time, but until as recently as 2014 they had not had a simple mechanism to purchase them. The opening of Chinas huge capital market which is in progress expands the opportunities for Russian investors to diversify their investment portfolios this is especially important in the face of the risk of various sanctions bans that may be imposed by the UK, the EU and the USA. From the standpoint of bilateral economic relations, the access of Russian investors to the Chinese stock and debt markets may contribute to increasing the volume of the currency derivatives market and, subsequently, expanding and strengthening the use of national currencies in trade between Russia and China. The article examines main causes and stages of the liberalization of the Chinese capital market, terms of trade through the Shanghai-Hong Kong Stock Connect and Shenzhen-Hong Kong Stock Connect, and the prospects for further opening of the Chinese capital market.

Aim: The purpose of this study is to compare the clinical criteria of preterm infants on their third day of life with their echocardiographic findings for the correct diagnosis of hemodynamically significant patent ductus arteriosus (hsPDA).
Material And Methods:The infants with a gestational age of <31 weeks and with a birth weight of <1250 g who underwent echocardiography on their third day of life were included in this retrospective study. The primary motive of this study is to identify whether clinical findings are feasible in the prediction of hsPDA.
Results: Of the 47 preterm infants, 29 had hsPDA (the hsPDA group) and 18 did not had patent ductus arteriosus (the control group). This observation was made by an echocardiographic examination. The rate of tachypnea and increased oxygen requirement were statistically significantly higher in the hsPDA group than in the control group (p = 0.01 and p = 0.004, respectively). The incidence of tachycardia and hypotension was statistically significantly higher in the hsPDA group than in the control group (p = 0.03 and p = 0.004, respectively). The rate of metabolic acidosis was significantly higher in the hsPDA group than in the control group (p = 0.005). There were no significant differences in murmur, hyperdynamic precordium, and widened pulse pressure between the groups. The incidence rates of tachycardia, hypotension, and metabolic acidosis were statistically significantly higher in the hsPDA group even when the rates of tachypnea increased the oxygen requirement. Thelogistic regression demonstrated that the metabolic acidosis was the only significant predictor of hsPDA [OR: 7.10 (p = 0.02, 95% CI: 1.34–37.53)].
Conclusion: Metabolic acidosis is the most reliable clinical finding for the prediction of hsPDA in the preterm infants on the third day of life.

Published: April 2020

Mikrobiyotanın kadın ve erkek fertilitesi üzerinde önemli etkilere sahip olduğu düşünülmektedir. Bu derlemenin amacı mikrobiyota ile infertilite arasındaki ilişkiyi inceleyen çalışmaları incelemek ve bu konuda sağlık bakım profesyonellerinin farkındalığını arttırmaktır. Yapılan çalışmalar kadın ve erkek genital organlarında birçok patojen ve nonpatojen etkenin yer aldığını ve baskın florayı oluşturan Lactobacillus’un fertilitenin korunmasında önemli etkileri olduğunu kanıtlamaktadır. Ayrıca ovarian follikül sıvındaki mikrobiyal etkenlerin gebelik sonuçlarıyla ilişkili olduğu gösterilmiştir. Bunun yanı sıra oral sağlığın da üreme sağlığı, gebeliğin oluşması ve fetal gelişim üzerine etkileri olduğu ortaya çıkartılmıştır. Erkek genitoüriner sistemine ait mikrobiyotanın üreme sistemi sağlığı ve fertilite üzerine etkileri olduğu çalışmalarda görülmüştür. Ancak seminal mayide yer alan patojenlerin kökeni net bir şekilde açıklanamamıştır. Üreme sağlığı açısından probiyotiklerin kullanımının fayda sağlayabileceği çalışmalarla desteklenmektedir. Mikrobiyotanın fertilite üzerine etkileri konusunda sağlık profesyonellerinin farkındalığının artması ve toplumun eğitilmesi gerekmektedir.

Published: April 2020

Amaç: Anjioleiomyom (ALM) sıklıkla alt ekstremite, baş ve gövde bölgesini içeren, iyi huylu bir perivasküler neoplazmadır. Uterin ALM oldukça nadir bir tümördür. Bu çalışmada olguların klinikopatolojik ve immünohistokimyasal özellikleri ve tedavi yöntemleri kapsamlı bir literatür taraması ile değerlendirildi.
Gereç ve Yöntemler: Hastanemiz patoloji servisine başvuran 5 uterin ALM vakası, patoloji veri tabanından bulundu. Vakaların Hemotoksilen-Eozin (HE) boyalı preparatları arşivden çıkarılarak yeniden gözden geçirildi. Vakalarda immünohistokimyasal olarak düz kas aktin (SMA), h-caldesmon, desmin, CD10, melan-A, HMB-45, ve WT-1 boyaları çalışıldı (Ventana benchmark XT).
Bulgular: Hastaların ortalama yaşı 40 idi. Hastaların hepsinde hastaneye başvuru sebebi anormal uterin kanama ve abdominal ağrı idi. 1 vakada (multipl ALM vakası) infertilite şikayeti de mevcuttu. 4 vakada tek bir tümör kitlesi izlenmekteyken, 1 vakada multipl tümör odağı (2 ayrı tümör odağı) mevcuttu. Tümör boyutu en küçük 5.2 cm, en büyük 10 cm olarak saptandı. 1 vakada tümör submukozal yerleşimli olup, diğer 4 vakada intramural yerleşimliydi. Makroskobik olarak tüm vakalar keskin sınırlı, solid, beyaz gri renkte, girdapsı nodüler görünümdeydi.2 vakada solid ve venöz varyant, 1 vakada venöz ve kavernöz varyant, 1 vakada venöz varyant, 1 vakada da her üç varyant izlendi.Vakaların hepsi desmin, h-kaldesmon, düz kas aktin ile boyanırken; CD10, melan-A, HMB-45 ve WT-1 ile boyanma izlenmedi.
Sonuç: Uterin ALM oldukça nadir, benign bir tümör olup, spesifik görüntüleme bulguları olmadığından preoperatif tanı son derece zordur. Tanı ancak patolojik çalışma ile mümkündür. Bu nedenle, klinisyen ve patoloğun bu nadir görülen tümörü hatırlaması ve histopatolojik inceleme ve gerektiğinde uygun immünohistokimyasal panel ile benzerlerinden ayırması önemlidir.

Bambusa tulda is highly economical bamboo, playing an important role as non-timber raw material for large number of products. Forest resource of this bamboo is depleting at a high rate and hence to meet its growing demand in commercial sector, technique for industrial production is required. The present experimental studies were carried out for rapid and mass clonal propagation of B. tulda covering two major aspects of propagation i.e. estab-lishment of aseptic culture and adventitious rhizogenesis. Organogenetic mode of regeneration of plant tissue culture technique has been employed for massive production of this bamboo species. The treatment of explant with Dettol (0.4%) for 10 mins and Bavistin (0.2%) for 30 mins followed by Ethyl alcohol (70%) for 35 seconds and HgCl2 (0.1%) for 10 mins resulted with maximum number of survival of aseptic cultures. The effect of MS medium+ additives+ NAA (0.25mg/l) supplemented with TDZ (0.5mg/l) showed maxi-mum (96%) shoot initiation. Maximum root growth (8.8cm) and number (approx 7 roots/ clump) was observed in ½ strength of MS with IBA (4mg/l) supplemented with coumarin (4mg/l). Seventh sub-culture cycle/ passage was the most suitable and the earliest possible passage of cultures (sub-culturing) for generation of profused in vitro rooting. The establishment of aseptic in vitro cultures and profused adventitious root induction derived from above studies will further help in industrial production of quality planting material of B. tulda within short span of time.

Objective: This study aimed to present characteristics of internationally published articles about emergency medicine originating from Turkey between 2002-2012 years.Methods: For our evaluation, all articles about emergency medicine published in Science Citation Index and Science Citation Index Expanded between 2002-2012 years were included. The articles were categorized according to subjects, hospitals, departments, years. The International Scientific Indexing Web of Knowledge was searched for all articles.Results: A total of 1812 articles were included. Of all articles, 64,3% (n=1165) were published in the last five years. Publications in the last five years were detected to increase at a rate of 4,6% per year. 78,1% (n=1416) of the articles were published in non-Emergency Medicine journals. “Turkish Clinics” journal in the non-Emergency Medicine journals group, with 46 articles, and the "Turkish Journal of Trauma and Emergency Surgery" in the Emergency Medicine group, with 134 articles, were the preferred journals. The most popular subjects were trauma, at 14,7% (n=266), followed by emergency medicine and management, at 14% (n=253). Conclusion: Significant publication growth was detected related to the development of Emergency Medicine in Turkey. The preference of non- Emergency Medicine journals, trauma as the most popular subject, and the effect of university hospitals were the interesting results of this study. The low number of multicenter trials and published articles in high impact factor journals have led us to consider the importance of publication quality, which requires additional effort.
