Detection and Location of Earth Fault in MV Feeders Using Screen Earthing Current Measurements
Authors: Lowczowski Krzysztof , Lorenc Jozef , Zawodniak Jozef , Dombek Grzegorz
Published: March 2020

The paper analyzes the utilization of cable screen currents for earth fault identification and location. Attention is paid on cable and mixed feeders—cable and overhead lines. The principle of operation is based on utilization of 3 criterion values: Ratio of cable screen earthing current and zero sequence cable core current—RF110/15, phase shift between cable screen earthing current and zero sequence cable core current—α and cable screen admittance defined as a ratio of cable screen earthing current and zero sequence voltage—Y0cs. Earth fault location is possible thanks to discovered relation between RF110/15 and α, whereas Y0cs allows for reliable detection of earth faults. Detection and identification are very important because it allows to increase the reliability of supply—reduce downtime and number of consumers affected by the fault. The article presents a phase to ground fault current flow for different power system configurations. At the end solution, which improves location capabilities is proposed. The solution is analyzed in PSCAD software and verified by network experiment.
Fault Location Method Using Phasor Measurement Units and Short Circuit Analysis for Power Distribution Networks
Authors: Hong Ji-Song , Sim Gi-Do , Choi Joon-Ho , Ahn Seon-Ju , Yun Sang-Yun
Published: March 2020

This paper proposes a fault location method for power distribution networks using phasor measurement units (PMU) and short circuit analysis. In order to improve the problems of the existing studies, we focused on several approaches as follows. First, in order to minimize the number of PMU installations, a fault location estimation of lateral feeders through short circuit analysis was presented. Second, unbalanced faults and impacts of photovoltaic (PV) were considered. The proposed method consists of two stages. In Stage 1, the fault location was estimated for the main feeder using PMU installed at the start and end points of the main feeder. Symmetrical components of voltage and current variation were calculated by considering the impact of PVs interconnected to the lateral feeders. If the result of Stage 1 indicated a connection section of lateral feeder on the main feeder, Stage 2 would be performed. In Stage 2, the fault location was estimated for the lateral feeder by comparing the results of the short circuit analysis and measurements of PMUs. The short circuit analysis was based on an unbalanced power flow that considered dynamic characteristics of the PV inverter. The proposed method was verified through various fault situations in a test system. For the applicability of the proposed algorithm to the actual system, a noise test was also performed.

Authors: ÇERÇİ Ece , ERDOST Hatice
Published: March 2020

The therapeutic potential of the adipose tissue is also supported by a source of mesenchymal stem cells (MSCs), endothelial progenitor cells, mast cells, T- lymphocyte, B lymphocyte, and adipose-resident macrophages with repairing and regenerative ability. The purpose of this study was to compare adipose tissue derived mesenchymal stem cells (ADSCs) and stromal vascular fraction cells (SVF cells) in terms of the usage of non-enzymatic isolation, detection of cell adhesion, fibroblastoid cell formation, properties of cell population, cell culture duration until 3rd passages under in-vitro culture condition. We used 3 months old, 4 male Sprague Dawley rats (mean of live weight about 250 g) to examined the variation of the cell population, cell properties, phases of cellular formation, cell culturing time, subculturing duration, differences in confluency between SVF cells and ADSCs. In in-vitro expansion, ADSCs displayed higher rate of adhesiveness, homogenous cell population, faster proliferation and formation of fibroblast like cells compared to SVF cells. As a result, we showed that ADSCs have better adhesive ability, higher proliferative capacity in all of the 3 passages and require shorter time to reach confluency compared with SVF cells in vitro. These findings may contribute to future studies that deal with isolation and selection of stem cells from various tissues, as well as design clinical trials based on ADSCs and SVF cells.
India in Yeats’s Early Imagination: Mohini Chatterjee and Kālidāsa
Authors: Dutta Ashim
Published: March 2020

W. B. Yeats’s interest in India persisted throughout his variegated life and career, starting in the late nineteenth century and lasting through the final decade of his life. This article concentrates on his early years when he first came to terms with Indian philosophy, religion, and literature via the Vedāntist-Theosophist Mohini Chatterjee and the work of the fifth-century Sanskrit playwright Kālidāsa. With a view to examining critically Yeats’s creative engagement with, and appropriation of, these disparate materials, this article closely reads a discarded 1880s poem on Chatterjee’s teaching and its later 1929 version, “Mohini Chatterjee,” as well as his early Indian poems, collected in Crossways. The reading of these poems is supplemented by critical analysis of the relevant Indian texts, which will illuminate the poems concerned as well as the extent of Yeats’s imaginative improvisation.

Donna, che fosti tra le donne un Sole»: sui tentativi poetici giovanili di Paolo Paruta (metà XVI sec.)
Authors: Giani Marco
Published: March 2020

During the mid-1560s, Paolo Paruta (1540-1598), future Ambassador of the Republic of Venice in Rome (1591-1595) and author of the three books of Perfettione della Vita Politica (Venice, 1579) wrote some poems: the canzone Donna, che fosti tra le donne un Sole, and three somnets. The former was then published in Dionigi Atanagi’s Rime di diversi nobilissimi et eccellentissimi autori, in morte della Signora Irene delle Signore di Spilimbergo (Venice, 1561), the latters were insert in Diomede Borghesi’s anthology for Cinzia Braccioduro Garzadori (then published in Padua, 1567, without Paruta’s somnets).

Writing those juvenile poems and making them circulate among the Venetian literary circles (such as Domenico Venier’s), Paruta was looking not only for artistic approval, but also for social visibility: the canzone and the somnets were part of his wider strategy for social climbing inside Venetian patrician ruling class.
Siete voi qui, ser Brunetto?». I volti di Brunetto Latini: rappresentazione e autorappresentazione
Authors: Ótott Noemi
Published: March 2020

As in portrait (attributed to Giotto) of Brunetto Latini and Dante Alighieri, history has tended to pair the two poets, who were both exiled from their native Florence. The role played by Brunetto Latini in Florence’s history paralleled that of the orator Cicero in Republican Rome and Dante, his student, was Florence’s Virgil. The famous “Brunetto’s Song” (Canto XV of Inferno) has generated many controversies, determined and justified by an uninterrupted and secular reflection. The encounter between the protagonist-traveler and his master has great importance also from the point of view of the creation of The Divine Comedy. But the old florentine intellectual does not only appear in this canto: in fact, he is the author and, at the same time, the protagonist of the famous opera Il Tesoretto, a didactic-allegorical poem written in volgare. In my study I focus on the figure of Brunetto Latini and on his representation by Dante. At first I examine the protagonist Latini: how he appears in the canto and what his part is in The Divine Comedy. Then I concentrate on the author Latini and I try to identify the poet’s voices in the texts and descriptions according to the context.

Ondina e le ondine Questioni di raffigurazione (verbale e iconografica) della donna sportiva nell’Italia fascista (1933 ca.)
Authors: Giani Marco
Published: March 2020

In late 1933, L'Osservatore Romano fuelled an argument against Il Littoriale, mouthpiece of the Fascist sport policy, about women’s sport: the Vatican Italian-speaking newspaper was against the public women’s athletic meetings, and the “immoral” shorts dressed by the young Italian athletes, such as Ondina Valla, going-to-be the first Italian woman to win an Olympic gold medal (1936, Berlin). Which was the situation of Italian female sports, at that time? Which was the influence of new women models coming from US? What was considered “immoral” by conservative people in 1933 Italy watching a women’s athletic or swimming meeting? How Hollywood stars could help Ondina and her mates on the road of female emancipation? These are the questions this essay is going to answer, helped by a lot of historical images, useful to reconstruct a whole collective imagination.
Digital models based on images taken with handheld cameras – examples on land, from the sea and on ice
Authors: Vest Sørensen Erik , Bjerager Morten , Citterio Michele
Published: March 2020

Geological outcrops can be comfortably modelled in three dimensions in the office using images from a handheld digital camera. Recent developments within the imaging techniques of Structure from Motion (Lowe 2004; Snavely et al. 2008; Fonstad et al. 2013) and photogrammetry (Hirschmüller 2005; James & Robson 2012; Favalli et al. 2012) have made it easier and cheaper to construct so-called digital outcrop models using stereoscopic images from standard digital cameras. The digital outcrop model (Bellian et al. 2005) is a 3D representation of the outcrop surface and is often displayed in the form of a polygon mesh or a point cloud. In this paper we present three examples of such point clouds from images obtained with a handheld digital camera. The examples illustrate how outcrop topography or digital outcrop models can be constructed at different scales, with different accessibility and operational platforms. Two examples illustrate outcrop scales of metres to kilometres, with images obtained by walking along excavated exposures in the Faxe limestone quarry and from a boat sailing past the coastal cliff of Stevns Klint. The third example illustrates detailed micro-topography of ice and snow surfaces where the images were obtained from a snowmobile on an ice cap in A.P. Olsen Land, North-East Greenland.
Investigations of detrital zircon, rutile and titanite from present-day Labrador drainage basins: fingerprinting the Grenvillean front
Authors: Thomsen Tonny B. , Knudsen Christian , Hinchey Alana M.
Published: March 2020

A multidisciplinary provenance study was conducted on stream sediment samples from major rivers in the eastern part of Labrador, Canada (Fig. 1). The purpose was to fingerprint the sources that deliver material to the stream sediments and to the reservoir sand units deposited off shore in the sedimentary basins in the Labrador Sea. We used a multimineral U-Pb geochronological approach employing rutile and titanite in addition to zircon to obtain unbiased age data. The purpose of this was to characterise the different igneous and metamorphic episodes that occurred in Labrador, which is an area with highly variable geology characterised by the Palaeoproterozoic south-eastern Churchill province in the north-west, the Archaean Nain plutonic suite in the north-east, the Palaeoproterozoic Makkovik province in the east and the Mesoproterozoic Grenville Province to the south. The field work was carried out in 2012 and 2013 and the study is a collaborative project between the Geological Survey of Denmark and Greenland and the Geological Survey of Newfoundland and Labrador. In this paper we focus on three samples from the southern part of the study area where two parts of the Grenville orogeny are found (Fig. 1).

Authors: Jamal Farrukh , Reyad Hesham Mohammed , Ahmed Soha Othman , Shah Syed Muhammad Akbar Ali
Published: March 2020

This paper presents the details of a proposed continuous model for the minimum Gumbel Burr distribution which is based on four different parameters. The model is obtained by compounding the Gumbel type-II and Burr-XII distributions. Basic mathematical properties of the new distribution were studied including the quantile function, ordinary and incomplete moments, moment generating function, order statistics, Rényi entropy, stress-strength model and stochastic ordering. The parameters of the proposed distribution are estimated using the maximum likelihood method. A Monte Carlo simulation was presented to examine the behaviour of the parameter estimates. The flexibility of the proposed model was assessed by means of three applications.

OPTIMIZATION OF THE PROFESSIONALS SELECTION AND TRAINING BY ARTIFICIAL INTELLIGENCE
Authors: Gómez-Martínez Raúl , Purswani Ravi , Prado-Roman Miguel
Published: March 2020

The investment in training and the improvement in the professional's abilities should anticipate an evolution in the professional's performance, but how could we estimate the probability of performance improvement from a formative action? The present work tries to quantify this using a study on 447 surveys carried out by Overlap consultant firm to professionals of the sales force of one of its clients. With this information, an artificial intelligence model has been trained. This model quantifies the relationship between skills and training on the performance of the professional and allows to measure how the probability of a better performance would increase after a training course or improvement capacity. Thus, the artificial intelligence model can be used to define the optimal profile of the professional that should carry out this activity, a profile to seek in the selection processes and in the planning of the company's internal training.

Published: March 2020

Apresentamos neste artigo um olhar sobre a centralidade das crianças na festa e na brincadeira do boi de Garrote na cidade de Manaus. Atentos a possibilidade de relacionamos sentidos do lazer às ricas relações da experiência cultural, propomos uma aproximação de uma das manifestações do boi-bumbá, que guarda vários universos de práticas de acordo com sua região. Em um universo em que, para muitos moradores da cidade, era visto como algo que não mais existia, buscamos revelar como este folguedo é uma prática viva e atuante, que revela modos de interação social entre crianças e suas vizinhanças. Ao problematizarmos sua manifestação como tempo-espaço observamos diversos modos de organização que escapam aos sentidos modernos do espetáculo e da vida fragmentada e individualizada. Ao estabelecer relações entre a dança, a criança, a educação e a cultura, buscamos caminhos de aproximação do lazer com o campo antropológico, enfatizando na cultura popular uma maneira singular de brincar o boi e uma prática criada para e pelas crianças.

Published: March 2020

A pesquisa buscou analisar o corpo em sua interlocução com a máscara no Carnaval de Veneza a partir da descrição da festa e do diálogo com a Antropologia da Performance (SCHECHNER, 2006). Para tanto, foram realizadas incursões, seguindo orientações da etnografia, nos carnavais de 2013 e 2014 na referida cidade, o que permitiu a apreensão do cotidiano festivo e o contato com foliões mascarados, a partir de entrevistas e registro imagético, para a apreensão da relação entre corpo e artefato estético. Dessa interlocução deflagra-se o pensamento de que a máscara representa mais do que um artefato contemplativo, levando-o a novas experiências corporais relacionadas à criação artística e estética e à representação cênica geradas no contexto carnavalesco. Por fim, os foliões mascarados assinalam o entendimento dialético de que o corpo expressa-se como máscara assim como a máscara se expressa como extensão do corpo, criando um híbrido, expresso pela figura do corpo mascarado.

Authors: Lou Tai-shan , Han Dong-xuan , Yang Xiao-liang , Jiang Su-xia
Published: March 2020

To improve the state
estimation accuracy of nonlinear induction motor with uncertain parameters, a
robust desensitized rank Kalman filtering (DRKF) is proposed to reduce state
estimation error sensitivities to uncertain parameters. A new sensitivity
function is defined, and a novel desensitized cost function for the
deterministic sampling methods is designed to obtain an optimal gain matrix.
The sensitivity propagation is summarized for deterministic sampling methods.
Based on the rank sample rule, the sensitivity propagation method is given, and
the DRKF algorithm is derived. Two dynamic behaviors of the induction motor
with two uncertain stator and rotor resistances are simulated to demonstrate that
the proposed DRKF has an excellent performance.

Spectrophotometric Determination of Copper (II) with 5-Hydroxy-6-Mercapto-Benzo [a] Phenazine
Authors: Reiss Aurora , Mureseanu Mihaela , Muresan Nicolae
Published: March 2020

5-Hydroxy-6-mercapto-benzo [a] phenazine (HMBP) is proposed as a sensitive and selective analytical reagent for the extractive spectrophotometric determination of copper (II). Copper reacts with HMBP to give a dark red complex which is soluble in chloroform. The composition of the CuII � HMBP complex is established as 1:2 by Job�s continuous variation method and molar ratio method. The instability constant of the complex calculated by Job�s relation for nonisomolar series is 4.65 . 10-9, at room temperature. The CuII-HMBP complex in chlorophorm shows a maximum absorbance at 495 nm, with molar absorptivity and Sandell�s sensitivity values of 7.39 . 103dm3 mol-1 cm-1 and 0.012 mg cm-2, respectively. Beer�s law is obeyed in the concentration range 0.67 - 26.90 mg mL-1 and the detection limit is 0.59 mg mL-1. A repetition of the method is checked by finding the relative standard deviation (RSD) at 1.00 mg mL-1 CuII of 0.6%. The method is successfully employed for the determination of copper (II) in environmental samples. The reliability of the method is assured by analysing the standard alloys and by inter-comparison of experimental values, using an atomic absorption spectrometer.

Published: March 2020

The following glycosides of cholesterol have been synthesized: a-D-galactofuranoside, �-D-glucopyranoside, bis-sulfo-3,6-b-D-glucopyranoside. 1-a-Bromides of protected sugars were used as glycosylation donors: tetra-O-benzoyl-D-galactofuranosyl and tetra-O-acetyl-D-glucopyranosyl. Peracylated sugars, i. e., precursors of sugar bromides, were synthesized in conditions that preferentially facilitated the envisaged ring: room temperature for pyranosic ring, high temperature for furanosic one. Constantly, cadmium carbonate was used as promotor. As a general scheme of work, glycosylation mixture was submitted to Zemplen saponification and the obtained glycolipids have been separated by characteristic methods. The glucoside of cholesterol was sulfated with chlorosulfonic acid in pyridine. Neutral or acidic glycolipids were characterized per se by chromatographic and chemical means as well as by IR spectroscopy. Sulfatide and galactocerebroside of rat brain and ganglioside GM4 of rooster testis were used as reference compounds. Alternatively, the synthesized glycosides were peracetylated and their 1H and 13C NMR spectra registered. New NMR spectroscopic data are presented for cholesteryl-a-D-galactofuranoside and -bis-sulfo-6-b-D-glucopyranoside.

Published: March 2020

The peculiarities of surface chemistry, functional groups and acid-basic properties of activated carbons obtained from vegetal raw materials by different methods of activation have been emphasized. Active carbons obtained from peach and plum stones by physical-chemical activation (with steam, aqueous solutions of sulfurous anhydride or ammonia) possess predominantly basic functional groups on the surface, although acidic sites in minor quantities are also accumulated. FTIR spectra suggest the presence on the surface of these carbons of alcoholic and phenolic groups, quinones and hydroxy-ketones. Active carbons obtained from plum stones, nut shells and grape seeds by chemical activation with phosphoric acid possess predominantly acidic functional groups on the surface, out of which carboxylic groups are prevailing by 2-3 times the content of phenolic structures. FTIR spectra suggest the presence on the surface of these carbons of a series of organic structures including carboxylic acids, ketones, aldehydes, quinones, lactones and esters, also alcohols and phenols. UV-VIS-NIR spectra also indicate the presence of alcohols and phenols on the surface of these carbons.

Authors: Miron Cristina
Published: March 2020

Electroconvection patterns have been studied in a homeotropic nematic liquid crystal, experimental and theoretical, with unusual combination of material parameters, negative conductivity and positive dielectric permittivity anisotropies. Exploring the complete phase diagram in the (U, q) space three distinct morphologies, rolls and squares, soft squares and hard squares have been identified. We perform a linear and nonlinear analysis of the full nematohydrodynamic equations and carry out simulations of a suitably constructed Lorenz model. We obtain in agreement with the experiments modulated rolls and squares at threshold.
