A cost effective accumulator management system for electric vehicles
Authors: D Suchitra , R Rajarajeswari , Bhati Dhruv Singh 
Published: August 2020

Abstract
An accumulator or battery is an energy storage cramped in an adaptable stockade. Lithium-ion batteries are commonly used in hybrid electric vehicles (HEV) and battery operated electric vehicles (BOEV) due to its eco-friendliness and increased efficiency. To maintain lithium batteries in the safe operating region and also to perform tasks like cell balancing, preventing thermal runaway, maintain the state of health, an effective battery management system (BMS) is required. The BMS should also communicate effectively between host devices and battery packs. This paper proposes a reliable, modular and cost-efficient BMS, which will emanate an alert when a fault occurs and thus preventing the battery from damage. An efficient control strategy has been proposed for charging and discharging of the battery pack. The thermal analysis of the lithium-ion battery used in this work is simulated using battery design studio (BDS) with the inclusion of a self-discharging effect. The proposed hardware setup also provides a provision for on-board diagnosis (OBD) and logging in the accumulator management system (AMS) to constantly monitor the cell parameters like voltage, current, and temperature. The live data display of AMS working is also shown during abnormal and normal conditions. Also, an attempt is made to use the design of proposed AMS for HEV.

Published: August 2020

Abstract
The advances in Wide Area Measurement Systems (WAMS) and deployment of a huge number of phasor measurement units (PMUs) in the grid are generating big data volume. This data can be used for a variety of applications related to grid monitoring, management, operation, protection, and control. With the increase in this data size, the respective storage capacity needs to be enhanced. Also, communication infrastructure readiness remains bottleneck to transfer this big data. One of the probable solutions could be transmitting compressed data. This paper presents techniques for data compression in the smart transmission system using singular values decomposition (SVD) and the eigenvalues decomposition (EVD). The SVD and EVD based principal component analysis (PCA) techniques are applied to the real-time PMU data collected from extra-high voltage (EHV) substations of transmission utility in the western regional grid of India. Adequacy of data is checked by Kaiser-Meyer-Olkin (KMO) test in order to have the satisfactory performance of these techniques towards achieving the objective of efficient data compression. Results are found satisfactory gives compression more than 80% using real time data.
Antioxidant and in vitro digestion property of black rice (Oryza sativa L.): a comparison study between whole grain and rice bran
Authors: Zhang Hui , Kai Guoyin , Xia Yongjun , Wang Guangqiang , Ai Lianzhong 
Published: August 2020

Abstract
A comparison study between whole grain and rice bran to evaluate the antioxidant activity and starch digestion property of black rice was conducted. Total phenolics content (TPC) and total anthocyanins content (TAC) analysis found that TPC and TAC contribution of rice bran to the whole grain were over 73 and 91%, respectively. Cyanidin-3-glucoside with minor peonidin-3-glucoside were identified in all whole grain and rice bran samples by HPLC-ESI-MS. The rice bran exhibited much stronger antioxidant activities than the whole grain, acting as the major antioxidant contributor to the black rice due to the high levels of TPC and TAC. In vitro digestion analysis found that rice bran could significantly decrease the digestibility and predicted glycemic index (pGI) of rice flour by lowering the rapid digestion starch and increasing the resistant starch (RS). This study revealed that rice bran could be a potential edible resource of phenolic-enriched antioxidant and glycemic regulator in food industry.

Published: August 2020

Abstract
In this study, yeast was isolated from cherry wine lees by rose Bengal medium, and its species was identified through three-stage screening, morphological observation and molecular biological identification. Moreover, the tolerance of screened strains was studied. The results showed that 30 strains of yeast were isolated from cherry wine lees, and five strains of yeast were selected, which were named YJN10, YJN16, YJN18, YJN19 and YJN28. After preliminary appraisal, strain YJN10 was Saccharomyces kudriavzevii, strain YJN16 was Saccharomyces paradoxus, and strains YJN18, YJN19, YJN28 were Saccharomyces cerevisiae. In the tolerance study, the tolerable sugar concentrations of the five strains were 650, 650, 550, 600 and 600 g/L. The tolerable alcohol volume fractions were 20, 20, 16, 18 and 18%. The tolerable molar concentration of potassium chloride was 1.8, 1.8, 1.5, 1.5 and 1.5 mol/L. Finally, strains YJN10, YJN16, YJN19 and YJN28 showed good tolerance, which laid a foundation for subsequent application in cherry wine fermentation.

Abstract
This paper focuses on designing of a 10 Gbit/s-10GHz hybrid Orthogonal frequency division multiplexing (FDM) based Radio over Free Space Optics (Ro-FSO) transmission link using optical single sideband modulation format and its performance has been compared using a different number of transmission beams. The proposed link has been simulated and compared using 1-beam, 2-beam, and 4-beam in the system. We show that by using the 4-beam system in the OFDM-Ro-FSO link, a 3000 m range has been achieved reliably, which a notable improvement when compared to previous work is. Also, we show an improved performance of the system by using an enhanced detection mechanism using a Square root module (SRm) at the receiver side.

Abstract
An issue of the novel coronavirus infection spreading is currently in the first place among others in the list of the international medical community. Due to lack of information, conflicting research findings, multicomponent effect of the virus on the body host, as well as various consequences that the virus triggers in the body, now every medical specialty does study the viral attack pathogenesis. Recent months showed that vascular complications are the most severe in the Coronavirus Disease 2019 (COVID-19) and are the main cause of death in the patients. The mechanisms of vascular complications are complex and affect both the hemostatic system and immune responses, “inflammatory storm”, disorders of the renin-angiotensin-aldosterone system, endotheliopathy, etc.
Due to the leading role of vascular complications in the viral infection pathogenesis, several groups of patients are at extra risk, including pregnant women, patients with a burdened obstetric history, with hereditary thrombophilia and antiphospholipid syndrome, and patients after in vitro fertilization (IVF). In this category of pregnant women, use of low-molecular-weight heparins (LMWH) is particularly important for both prevention of vascular and obstetric complications, and for pathogenetic therapy of COVID-19.
Subject-Contextualism and the Meaning of Gender Terms
Authors: Zeman Dan 
Published: August 2020

AbstractIn this paper, I engage with a recent contextualist account of gender terms (particularly, “woman”) proposed by Díaz-León, E. 2016. “Woman as a Politically Significant Term: A Solution to the Puzzle.”Hypatia31 (2): 245–58. Díaz-León’s main aim is to improve both on previous contextualist and non-contextualist views and solve a certain puzzle for feminists. Central to this task is putting forward a view that allows trans women who did not undergo gender-affirming medical procedures to use the gender terms of their choice to self-identify. My goal is to investigate Díaz-León’s proposal, point out (what I take to be) several shortcomings of the view and discuss possible replies on her part.

A family study of congenital dysfibrinogenemia caused by a novel mutation in the FGA gene: A case report
Authors: Qiao Yingli , Zhang Qisi , Xu Poshi , Deng Yuhui 
Published: August 2020

Abstract
Congenital dysfibrinogenemia (CD) is a rare hereditary fibrinogen disorder characterized by normal fibrinogen antigen levels associated with lower functional activities. The aim of this study is to analyze the phenotype and genotype of a family of CD. Routine coagulation screening tests were performed on the proband, her parents, and her grandparents. Then, the purified genomic DNA extracted from peripheral blood was amplified by PCR, and Sanger sequencing was performed to further confirm the mutation. The prothrombin time and activated partial thromboplastin time of the proband were normal, thrombin time prolonged, and the activity of fibrinogen (Fg:Ac) decreased significantly, but fibrinogen antigen (Fg:Ag) level was normal. The coagulation function indices of the proband’s father and grandfather were similar to her, and the indices of her mother and grandmother were normal. Sequencing results showed that the proband had a heterozygous missense mutation in FGA gene c.92G > A, which caused the mutation of amino acid 31 from glycine to glutamic acid (p.Gly31Glu). Her father had the same heterozygous mutation. In conclusion, the proband suffered from CD. The change of Gly31Glu in A chain due to the c.92G > A heterozygous missense mutation in the FGA gene is the cause of CD in the family. To the best of our knowledge, the mutation site is new and first reported so far.

The Lindley negative-binomial distribution: Properties, estimation and applications to lifetime data
Authors: Mansoor Muhammad , Tahir Muhammad Hussain , Cordeiro Gauss M. , Ali Sajid , Alzaatreh Ayman 
Published: August 2020

Abstract
A generalization of the Lindley distribution namely, Lindley negative-binomial distribution, is introduced. The Lindley and the exponentiated Lindley distributions are considered as sub-models of the proposed distribution. The proposed model has flexible density and hazard rate functions. The density function can be decreasing, right-skewed, left-skewed and approximately symmetric. The hazard rate function possesses various shapes including increasing, decreasing and bathtub. Furthermore, the survival and hazard rate functions have closed form representations which make this model tractable for censored data analysis. Some general properties of the proposed model are studied such as ordinary and incomplete moments, moment generating function, mean deviations, Lorenz and Bonferroni curve. The maximum likelihood and the Bayesian estimation methods are utilized to estimate the model parameters. In addition, a small simulation study is conducted in order to evaluate the performance of the estimation methods. Two real data sets are used to illustrate the applicability of the proposed model.
A new one-parameter discrete distribution with associated regression and integer-valued autoregressive models
Authors: Altun Emrah 
Published: August 2020

Abstract
This study introduces the Poisson-Bilal distribution and its associated two models for modeling the over-dispersed count data sets. The Poisson-Bilal distribution has tractable properties and explicit forms for its statistical properties. A new over-dispersed count regression model and integer-valued autoregressive process with flexible innovation distribution are defined and studied comprehensively. Two real data sets are analyzed to prove empirically the importance of proposed models. Empirical findings show that the Poisson-Bilal distribution has important application fields in time series and regression modeling.
On the bond pricing partial differential equation in a convergence model of interest rates with stochastic correlation
Authors: Stehlíková Beáta 
Published: August 2020

Abstract
Convergence models of interest rates are used to model a situation, where a country is going to enter a monetary union and its short rate is affected by the short rate in the monetary union. In addition, Wiener processes which model random shocks in the behaviour of the short rates can be correlated. In this paper we consider a stochastic correlation in a selected convergence model. A stochastic correlation has been already studied in different contexts in financial mathematics, therefore we distinguish differences which come from modelling interest rates by a convergence model. We provide meaningful properties which a correlation model should satisfy and afterwards we study the problem of solving the partial differential equation for the bond prices. We find its solution in a separable form, where the term coming from the stochastic correlation is given in its series expansion for a high value of the correlation.

y = δ(z)) whenever xy
⋆ = z (x

y = z), and under several conditions on 𝓐, δ and z we characterize the structure of δ. In particular, we prove that if 𝓐 is a Banach ⋆-algebra, δ is a continuous linear map, and z is a left (right) separating point of 𝓐, then δ is a Jordan derivation. Our proof is based on complex variable techniques. Also, we describe a linear map δ satisfying the above conditions with z = 0 on two classes of ⋆-algebras: zero product determined algebras and standard operator algebras.

Abstract
A field experiment was conducted to investigate the effect of aqueous and ethanolic extracts of neem (Azadirachta indica A. JUSS) and garlic (Allium sativum L.) against Cercospora leaf spot (CLS) disease of groundnut (Arachis hypogaea L.). A split plot design using two exotic (“fleur” 11 var., 65-13 var.) and one local (village var.) variety of groundnut as the main factor and ten treatments comprising one negative control (sterile distilled water), one positive control (fungicide: spavozeb) and eight phyto-extracts replicated three times was applied. Treatments were applied to plots at 45, 60, 75 and 90 days after planting (DAP). Results showed that CLS disease incidence ranged between 66.67% and 88.89% at 65 DAP for 10% ethanolic extract of garlic and 20% aqueous extract of garlic, respectively. Disease severity was lowest for 20% ethanolic extracts of neem seeds (14.74%) and garlic bulb (14.99%) at 65 DAP. Yield obtained from treatments of ethanolic extracts of garlic (3.62 t ha−1) was significantly higher (p < 0.05) than the control (2.40 t ha−1) but comparable to the spavozeb treatment (3.09 t ha−1). Exotic varieties were more productive (3.13 and 3.43 t ha−1) than the more resistant local variety (2.67 t ha−1).
Resonance overvoltage control algorithms in long cable frequency conversion drive based on discrete mathematics
Authors: Deng Yonghong , Zhang Quanzhu 
Published: August 2020

AbstractIn order to solve the problem that the long cable variable voltage and variable frequency (VVVF) system does not adopt an effective capacitor voltage sharing control method, resulting in a poor effect of resonance overvoltage control, the resonance overvoltage control algorithm of the long cable VVVF system based on discrete mathematics is studied. First, the long cable frequency conversion drive system is established. In order to ensure voltage loss in the range of motor requirements, a frequency converter–cable–motor (ICM) system connection mode is used to maintain the system operation. Based on the research of the capacitor voltage balance control strategy of a long cable frequency conversion drive system, the discrete mathematical model of the AC side of the ICM system is established by using this control strategy. The improved constant active power controller is obtained by establishing the mathematical model, and the resonant overvoltage in a long cable frequency conversion drive is realized by using the constant active power controller. The experimental results show that the algorithm can effectively control the resonance overvoltage phenomenon in the long cable frequency control system, and the control accuracy is over 97%. It has good performance and can be applied in practice.
3D bending simulation and mechanical properties of the OLED bending area
Authors: Ma Liang , Gu Jinan 
Published: August 2020

AbstractDue to the poor mechanical properties of traditional simulation models of the organic light-emitting device (OLED) bending area, this article puts forward a finite element model of 3D bending simulation of the OLED bending area. During the model construction, it is necessary to determine the viscoelastic and hyperelastic mechanical properties, respectively. In order to accurately obtain the stress changes of material deformation during the hyperelasticity determination, a uniaxial tensile test and a shear test were used to obtain data and thus to characterize the hyperelastic properties. In order to measure the viscoelasticity, a stress relaxation test was used to draw the stress relaxation curve, so as to characterize the viscoelastic properties. Then, the plane or axisymmetric stress–strain analysis was achieved, and the material parameters of the 3D model of the OLED bending area were obtained. Finally, the 3D model was applied to the 3D bending of the OLED bending area. Combined with the axisymmetric finite element analysis method, the 3D bending simulation finite element model of the OLED bending area was constructed by dividing the finite element mesh. Experimental results show that the mechanical properties of the proposed model are better than those of traditional OLED bending simulation models. Meanwhile, the proposed model has stronger application advantages.
