‘If this is Shakespeare, then I’m Virginia Woolf’
Authors: Egorova L. V.
Published: December 2018

A review of the bilingual edition of the play Double Falsehood, or, The Distressed Lovers, prepared by ‘Book Centre Rudomino’. The play is supplied with three presentations: a translator’s introduction by Andrey Korchevsky, a foreword by the most renowned scholar of this highly mysterious play, Brean Hammond (he edited the play for the Arden series in 2010), and an afterword by Dmitry Ivanov, a Russian scholar of the period and translation. Is there much left of Shakespeare and Fletcher in Double Falsehood, and what exactly is it? Can one single out the earliest language stratum stemming from Cardenio? Stylistic and metric similarities aside, can one indeed recognize Shakespeare and Fletcher on the higher level of the whole work: its plot, composition, mise en scfnes, images and ideas? Does Double Falsehood preserve traces of the original composition and plotline of Cardenio? The paper is published on the eve of this extensively commented edition of Double Falsehood becoming available to Russian reading audiences and theatre practitioners.
‘People and good books make me happy’. Ekaterina Livshits’ letters to Aleksandr Deich and Evgenia Deich-Malkina
Authors: Nerle P. M.
Published: December 2018

At the core of this publication are letters written by E. Livshits (1902–1987), the widow of B. Livshits, to her close friends: literary critic A. Deich (1893–1972), whom she knew ever since her Kiev days, and his wife E. Deich-Malkina (1919–2014). Kept at the Russian State Archive of Literature and Art, this epistolary collection spans over 20 years, starting from 1967. Along with accounts of private circumstances, each letter contains accounts related to B. Livshits, Osip and Nadezhda Mandelstam, I. Nappelbaum, A. Shadrin, and others. At the same time, E. Livshits’ comments and descriptions of people and literary works are very lifelike and fascinating. On the whole, the reader gets a picture of the period and certain literary process, viewed by a sophisticated connoisseur rather than squinted at by an aging disenfranchised widow of an executed writer. The publication is prefaced by P. Nerler, who collected and prepared the book of letters and reminiscences of E. Livshits, to be printed by Elena Shubina Publishers (AST).
Justified exoticism, or, Kabuki Theatre touring the Soviet Union in 1928
Authors: Kitamura Yu , Savelli D
Published: December 2018

The article offers a detailed account of the first tour of a Kabuki troupe in theSoviet Union, commenting on its political and cultural significance. Kabuki performers were invited to theUSSRfor primarily political reasons: establishing contact between the two governments came first, and the tour was regarded as a success for Soviet diplomacy rather than an achievement of Japanese culture. However, the political hype soon subsided and more people realized the extraordinary significance of this tour for the history of the theatre. The tour became a nation-wide event. The authors cite numerous newspaper reviews of the Kabuki plays, as well as correspondence between politicians, who had anticipated a flop, but were amazed at the reaction of Soviet audiences to this Japanese ‘exoticism’ because the tour had been mostly targeted at the Japanese community. The latter saw the tour as a sign of the Soviets’ readiness for peaceful coexistence withJapan.
‘...Insured against the tyranny of time’.Knut Hamsun’s last play and an unknown Russian film script
Authors: Lonngren T P.
Published: December 2018

After a short summary of the story behind K. Hamsun’s play In the Grip of Life [Livet i Vold], its plot and stage history in Russia, the article proceeds to tell about an unknown film script. Cinematic adaptations of Hamsun’s books have always dominated Norwegian literature, while none of his dramatic pieces have made it to the screen. However, a film script was uncovered, an adaptation of In the Grip of Life: a play specially written for a Russian theatre. The script was found in the Russian State Archive of Literature and Arts, among the documents of Evgeny Sergeevich Khokhlov. Based on the history of filmmaking and relevant filmography, Khokhlov’s film script is not just the only attempt at film adaptation of a Hamsun play, but the first ever project based on a theatrical play in Russian cinematic history. Written almost 100 years ago, the script is far from perfect in the modern understanding of filmmaking; nonetheless, it has certain merits in the eyes of contemporaries. The very attempt to interpret the play by means of a nascent artistic genre may be considered a proof of its relevance to Russian audiences at the time.

A useful way to approach the discourse of rights in African philosophy
is in terms of Kwasi Wiredu’s (1996) distinction between
cultural particulars and universals. According to Wiredu, cultural
particulars are contingent and context-dependent. They fail to hold
in all circumstances and for everyone (Wiredu 2005). Cultural universals
are transcultural or objective (Wiredu 2005). Examples of
cultural particulars include dress styles, religious rituals, social etiquette
and so on. One example of a cultural universal is the norm of
truth. One may imagine a society with different methods of greeting,
dress, and raising children, but one cannot imagine a robust
society which rejects the norm of truth as the basis of social practices.

Rekreasyonda Boş Zaman Ön Kabulünün Sınaması ve Yenilenme Perspektifi
Authors: KOÇAK Göknil Nur , ERYILMAZ Gamze
Published: December 2018

Bu çalışmanın iddiası, rekreasyonun bir boş veya serbest
zaman etkinliği olarak sınırlandırılmaması gerektiğidir. Bu çalışma, rekreasyon
katılımcılarının yenilenme beklentisi ile motive olduğu varsayımı üzerine inşa
edilmiştir. Yenilenme, rekreasyon katılımcılarının nihai fayda beklentisine
işaret eden yeni bir bilimsel kavramdır. Saha araştırması hem geleneksel boş
zaman temelli argümanı hem de yeni önerilen yenilenme kavramını test etmeye
olanak sağlayacak şekilde tasarlanmıştır. İlk analizlerin bulguları geleneksel
yaklaşımı destekler nitelikte; çalışmayanların daha fazla boş zamana sahip
oldukları ve çalışanlardan daha fazla yenilenme düzeyinde bulunduklarını
göstermektedir. Daha kapsamlı bir bakış sağlayan sonraki analizler, boş zaman
ile yenilenme arasında çok zayıf bir ilişki olduğu yönündeki iddianın
geçerliliğini desteklemektedir. Bu çalışmanın önemi; rekreasyonun boş/serbest
zaman sınırlamasına tabi bir olgu olmanın ötesinde, yenilenme şeklinde tezahür
eden nihai fayda odaklı bir oluş olduğunu göstermesinden kaynaklanmaktadır. Bu
yeni bakış açısının rekrasyon bilimi üzerine çalışan akademisyenler,
eğitimciler ve rekreasyon bölümü mezunlarının iş alanlarına yönelik yenilikçi
ve verimli tasarımlar yapabilmelerinin önünü açması ve rekreatif eğitim,
rekreatif ebeveynlik, rekreatif iş ortamları gibi yeni tasarımlar üzerinde düşünmeye
yönelinmesi önerilmektedir.
Primjena gnojiva na bazi fosfita u gnojidbi salate i ostalog lisnatog povrća
Authors: Gluhić David
Published: December 2018

Fosfor je važan biogeni element za sve poljoprivredne kulture, iako se potrebe za fosforom značajno razlikuju između pojedinih poljoprivrednih kultura. Fosfor je sastavni element adenozindifosfata (ADP) i adenozintrifosfata (ATP); spojeva koji su izvor energije za sve fiziološke procese u biljci. S druge strane, gnojidba fosforom je dosta problematična, zbog niza čimbenika koji smanjuju usvajanje fosfora. Stoga, je odnedavno, kemijska industrija gnojiva ponudila nove mogućnosti u problemu gnojidbe fosforom – gnojiva na bazi fosfita. Zbog niza pozitivnih učinaka u gnojidbi, gnojiva na bazi fosfita počinju se sve više koristiti za gnojidbu poljoprivrednih kultura, pa tako i lisnatog povrća, poput salate, blitve, špinata i drugog lisnatog povrća. Osim u folijarnoj gnojidbi, fosfiti se mogu koristiti u sustavima fertirigacije. U proizvodnji gnojiva fosfiti se mješaju sa ostalim elementima, poput kalija, magnezija, kalcija ili nekog mikroelementa, te se time dobivaju visoko koncentrirana gnojiva za upotrebu u poljoprivredi. Fosfiti su specifični spojevi koji osim na ishranu biljaka imaju i ostale pozitivne učinke u poljoprivrednoj proizvodnji. Primjena fosfita efektivno povećava otpornost biljke na bolesti uvjetovane gljivicama te povećava otpornosti i na bakterijske bolesti salate. Kako je salata kultura koja se uzgaja vrlo intenzivno u vrlo uskom plodoredu, ova pozitivna svojstva gnojiva na bazi fosfita su vrlo važna.

Individualism versus Collectivism Orientation as Moderator between Co-Workers’ Social Support and Work to Family Enrichment
Authors: Kumar Aneel , Channa Khalil Ahmed , Maharvi Muhammad Waqas
Published: December 2018

The purpose of this study was to test the effect of co-workers’ support on work to family enrichment and the moderating role of individualism/collectivism orientation in the relationship between social support and work to family enrichment. There were 243 respondents of banking sector on which the analysis was based. Primary data were collected through the five point Likert type of survey questionnaire. The findings of this study showed co-workers’ support as the potential antecedent of work to family enrichment. The workplace resource of co-workers’ support engendered the positive experiences of work to family enrichment in the employees. Further, individualism/collectivism orientation was found as the significant moderator in the relationship between co-workers’ support and work to family enrichment. The relationship was stronger for employees high on individualistic/collectivist orientation, as compared to those who were low on such orientation. These results validate the prevalence of collectivist cultural context in this part of world.

DEVELOPMENT OF A BIOSENSOR OF UREA WITH THE APPLICATION OF POLYMER TECHNOLOGIES FOR BLOOD AND URINE ANALYSIS
Authors: Ibadullaeva Saltanat  , Fomkina Maria  , Appazov Nurbol  , Zhusupova Laila
Published: December 2018

Based on polymeric nanotechnologies, enzyme sensors and microreactors have been developedin the way, that they can determine urea in liquids. The technology of manufacturing an enzymatic biosensor does not differ significantly from the known technology of manufacturing microcapsules with an enzyme by the laer-by-laer method. This allows us, when constructing a biosensor, to use the information obtained on encapsulated enzymes by other authors. It is shown that urea biosensor is able to work for a long time (up to 2 months) without significant loss of enzyme activity. Polymer technology for manufacturing sensors is less laborious and expensive compared to other similar technologies. We propose to develop biosensor devices – urea analyzers with polymer enzyme chips for express diagnostics of biological fluids (blood, urine). One of the significant results of this work from our point of view is two factors. The first factor is the optimization of the conditions for the production of a functionally active enzyme immobilized in a polyelectrolyte coating, when the enzyme after the immobilization procedure shows an activity comparable to that of a freshly prepared free enzyme. Such a result will allow reducing the cost of enzymes when creating a sensitive layer of the developed urea analyzer. And the second factor is that the polymer coating with the enzyme is able to work not only as an enzyme electrode, but also as an enzyme microreactor, without decreasing the rate of signal registration after passing the catalytic urease-urea reaction.
GENERAL CHARACTERISTICS OF INFLUENZA VIRUS A MOLECULAR STRUCTURE
Authors: Deryabina Nina  , Gritsenko Dilyara  , Galiakparov Nurbol
Published: December 2018

The influenza virus is one of the most abundant viruses in the world. It causes both mild seasonal infections and severe pandemics killing thousands of people and mammals. Two main extracellular receptors – neuraminidase (NA) and hemagglutinin (HA) are responsible for infection symptoms development and spread. Error-prone RNA-polymerase incorporates mutations into both neuraminidase and hemagglutinin per replication cycle, which complicates the development of highly effective drugs against animal influenza. Incorporated mutations are also involved in the transition of influenza from animal to human species and vice versa. Transited influenza subtypes are the most dangerous, because it is unpredictable now, where the mutation might arise. However, it starts to become clear, which molecular regions are the most common for the mutation to occur. This article revises the molecular structure of influenza extracellular receptors, including critical regions of receptors binding sites and susceptible mutation sites. The clear understanding of molecular structures and critical regions of HA and NA might facilitate the development of an effective vaccine and/or drug development.

Thе article presents the results of a molecular-genetics research on patients with diagnosed epilepsy without mechanical disturbance. The aim of this research was the analysis of candidate gene polymorphisms in development of different forms of epilepsy excepting mechanical reasons. 78 patients of V.M. Savinov SVS clinic with different forms of epilepsy were selected for the molecular-genetic analysis. Genotyping on candidate polimorphisms of gene coding the methyl-СрG-binding protein 2 (МЕСР2, 3 polymorphisms), the genes of sodium (SCN1A, 4 polymorphisms) and potassium (KCNT1, 2 polymorphisms) channels was performed by a site-specific PCR-RFLP method. Molecular genetic analysis revealed the presence of normal functioning alleles for 3 investigated candidate polymorphisms (p.Thr158Met, p.Thr197Met, p.Arg306Ter) of 3d exon of МЕСР2 gene at all epilepsy patients. However, 1 case (patient suffering from Dravet syndrome) of de novo mutation was defined for sodium channel gene (SCN1A p.Ala1783Thr) and 3 cases (2 patients suffering from temporal epilepsy and 1 patient with residual encephalopathy) of new mutations in gene responsible for potassium channel (KCNT1 p.Ala934Thr). To determine the inherited SCN1A and KCNT1 mutations, the molecular-genetics analysis was conducted for close relatives of patients. As a result, we conclude that, candidate polymorphisms of SCN1A p.Ala1783Thr and KCNT1 p.Ala934Thr, disrupting the ion channels normal functioning, can be involved in development of non-mechanical forms of epilepsy.
RIEMANNIAN METRIC FOR TEXTURE RECOGNITION
Authors: Makarenko N.G.  , ChoYong-beom  , Esenaliev A. B.
Published: December 2018

The article discusses the recognition of textures on digital images by methods of computational topology and Riemannian geometry. Topological properties of patterns are represented by segments (barcodes) obtained by filtering by the level of photometric measure. Beginning of barcode encodes level at which topological property appears (connected component and/or “hole”), and its end - level at which the property disappears.
Barcodes are conveniently parameterized by coordinates of their ends in rectangular coordinate system “birth” and “death” of topological property. Such representation in form of a cloud of points on plane is called a persistence diagram (PD). In the article show that texture class recognition results are significantly better compared to other vectorization methods of PD.

Published: December 2018

The analysis of platelet aggregation and thrombosis kinetics has significantly advanced with progress in microfluidic technology. However, the results of platelet aggregation tests do not fully reflect the observed clinical outcomes. To address the present unmet clinical needs, the basic but essential biology of platelets should be reconsidered in relation to the characteristics of microfluidic systems employed for platelet tests. To this end, the present article provides an overview of commercially available point of care devices and focuses on recent microfluidic studies, describing their measurement principles. We critically discuss the characteristics of the microfluidics systems used to evaluate the complex processes underlying platelet aggregation, and that are specifically designed to mimic the pathophysiological environment of blood vessels, including hemodynamic factors as well as blood vessel injury. To this end, we summarize unsolved issues related to the application of platelet function tests based on microfluidics. Overall, we confirm that platelet function tests based on microfluidics provide a versatile platform that encompasses a variety of basic research, as well as clinical diagnostic applications.

Background:

Caregivers providing informal care for people with dementia (PwD) often report unmet needs, burden, and health impairments. Optimal support for family dementia caregivers will likely benefit from better understanding and assessment of the prevalence and types of caregivers’ unmet needs and associated socio-demographic and clinical characteristics.

Objective:

The present study investigates 1) the number and types of caregivers’ unmet needs, 2) socio-demographic and clinical characteristics of both PwD and caregivers, and 3) caregivers’ burden and health-related outcomes that are related to caregivers’ unmet needs.

Methods:

The present analyses are based on cross-sectional data of n = 226 dyads of caregivers and their community-dwelling PwD participating in a comprehensive standardized, computer-based caregivers’ needs assessment within a general practitioner (GP)-based, cluster-randomized intervention trial.

Results:

A total of n = 505 unmet needs were identified for n = 171 caregivers from the intervention group at baseline. Only 24.3% caregivers reported no unmet need ( n = 55), whereas 75.7% caregivers had at least one unmet need ( n = 171). Caregivers had on average 2.19 unmet needs ( mean = 2.19, SD = 2.15). Specifically, 53.1% of caregivers had one up to three unmet needs ( n = 120), 18.6% ( n = 42) had three up to six unmet needs, and 4.0% ( n = 9) had more than six unmet needs.

Discussion:

Our results underline the importance of a comprehensive needs assessment for family dementia caregivers to develop and implement concepts that can provide family dementia caregivers with optimal support.

Published: December 2018

The etiology and pathogenesis of Alzheimer’s disease (AD) are not fully understood. Thus, there are no drugs available that can provide a cure for it. We and others found that DNA polymerase-β (DNA pol-β) is required for neuronal death in several neurodegenerative models. In the present study, we tested the effect of a DNA pol-β inhibitor 2′,3′– Dideoxycytidine (DDC) in AD models both in vitro and in vivo. DDC protected primary neurons from amyloid-β (Aβ)-induced toxicity by inhibiting aberrant DNA replication mediated by DNA pol– β. Chronic oral administration of DDC alleviated Aβ deposition and memory deficits in the Tg2576 mouse model of AD. Moreover, DDC reversed synaptic loss in Tg2576 mice. These results suggest that DDC represents a novel therapeutic agent for the treatment of AD.

Published: December 2018

Magnetic properties were imparted to a naturally nonmagnetic material by metallic inclusions. In this paper, microstrip based meandered radiating structure using artificial substrate has been reported. Here metallic split ring resonators are added in the conventional dielectric substrate to make artificial substrate material. The patch size is reduced 50% using the artificial material. Comparison of artificial substrate material design and conventional material design is shown in this paper. Artificial substrate Design has one band at 0.64 GHz centre frequency. Design results are obtained by a HFSS (High Frequency Structure Simulator) which is used for simulating microwave passive components.
Using multiple modes to reconstruct conductor locations in a cylindrical model of a power transformer winding
Authors: Dalarsson Mariana , Motevasselian Alireza , Norgren Martin
Published: December 2018

A study of a novel method to detect mechanical deformations of windings in a power transformer, while in operation, is presented. We employ an approximate model of a transformer winding surrounded by the transformer-tank wall and the magnetic core. The transformer winding is viewed as a structure consisting of thin conducting cylindrical rings (winding segments or turns) situated within a coaxial cylindrical waveguide, where the inner conducting cylinder represents the iron core that conducts the magnetic flux and the outer conducting cylinder represents the wall of the transformer tank. The basic principle is to insert antennas inside the transformer tank above and below the winding to radiate and measure microwave fields that interact with the metallic structure and the insulation. The responses from the radiated waves are assumed to be sensitive to any mechanical deformations that could be caused by electromagnetic forces due to short-circuit currents and possible manufacturing weaknesses. The goal is to be able to determine the radial locations of the individual winding segments or individual turns from measurements of the scattered fields at both ends. The propagation problem is solved by conventional waveguide theory, including mode-matching and cascading techniques. We utilize optimization as a suitable method to solve the inverse problem and obtain a good agreement between the reconstructed and true positions of the winding segments.

This paper presents a novel method for the Non-Parametric Modelling of Magneto-Rheological (MR) Dampers using Adaptive Neuro-Fuzzy (NF) that incorporates a Particle Swarm Optimisation (PSO) method. In this approach, the adaptive NF method is using an adaptive Back-Propagation (BP) learning algorithm, which is used to update the weights in real-time. Initial values of the weights and biases are optimised using PSO in an off-line manner. The experimental data was presented in the time histories of the displacement, the velocity and the force parameters, measured for both constant and variable current settings and at a selected frequency applied to the damper. The model parameters were determined using a set of experimental measurements corresponding to different current constant values. It has been shown that the MR damper model's response via the proposed NF approach is in a good agreement with the MR damper test rig counterpart.

Authors: Tang Mingsheng , Zou Huiming , Xu Hongbo , Shao Shangquan , Tian Changqing
Published: December 2018

The electromagnetic transduction coefficient has a strong influence on efficiency as well as the sensorless control of linear oscillation electrical machine (LOEM). This paper presents a reciprocal LOEM method for measurement of the electromagnetic transduction coefficient, to investigate the effect of the magnet length on the characteristics of the transduction coefficient. The result shows that the transduction coefficient has two regimes, a constant regime and a nonlinear regime. As the harmonic distortion begins to appear in the induced electromotive force, the electromagnetic transduction coefficient passes from the constant regime to the nonlinear regime, and the corresponding stroke is defined as critical stroke. The range of constant regime equals the observed critical stroke, and the critical stroke is 8.81 mm and 10.78 mm when the length of the permanent magnet is 11 mm and 13 mm respectively. The relationship among the geometrical dimension of yoke and permanent magnet, the critical stroke and the stroke of the LOEM are carefully investigated. Then optimal lengths for both the yoke and the permanent magnet are suggested for the LOEM design with the rated stroke, to achieve the highest efficiency and least material cost simultaneously.

Authors: Chang Lin , Lian Jie
Published: December 2018

The magneto-optical Kerr effect (MOKE) of ultrathin film grown on non-magnetic anisotropic substrate has been investigated. The formula of Longitude Magneto Optical Kerr effect for this structure is derived to find out the influence of the anisotropic substrate on the magneto optical properties of the sample. The change of Kerr rotation as a function of the incident angle is also given, which can be used to find a proper angle in sample measurement. Finally, a numerical simulation was carried out to find out the relation between Kerr rotation and optical properties of the anisotropic substrate which can be used to select suitable substrate on which the film grows.
Electromagnetic coupling through apertures and shielding effectiveness of a metallic enclosure housing electro-optic pockels cell in a high power laser system

Published: December 2018

This paper presents mathematical analysis and measurement results of electromagnetic couplings through a pair of intentional apertures in a metallic enclosure and its effect on the electromagnetic shielding effectiveness. The enclosure houses an electro-optical device (Pockles cell) and its high voltage drive circuitry. Two different aperture shapes i.e. rectangular and circular of equal areas are compared over frequency range of 200 MHz to 2 GHz. Pockels cells are commonly used in applications involving fast switching of polarization to block or transmit laser light. Pockels cell assemblies are housed in metallic enclosures to reduce noise emissions from high voltage pulser circuits driving the cell and to minimize the field couplings from external sources which may result into spurious switching of the cell. However, apertures are required in the enclosure to enable the laser beam to be incident on the Pockels cell and for onward transmission of the modulated beam. The apertures result into reduced shielding effectiveness of the metallic enclosure and increase in noise couplings. There is a need to understand the effect of apertures and to properly select their shapes and sizes such that the electromagnetic noise couplings are kept to a minimum acceptable level. Apart from the functional requirements of a reliable and noise free system operation, this issue is also important to meet the growing and stringent demands of electromagnetic compatibility. The analysis and measurements presented in this work pertain to the noise couplings from an external source into the enclosure through two differently shaped apertures i.e. rectangular and circular. For the comparison purpose, the planar areas of the apertures for the two cases are kept equal. The analysis and measurement techniques described in this work will be of interest to designers of electrical and electro-optical components for laser systems.
Investigation of circular waveguide with axially periodic thin metal disc inserts for wideband gyro-TWTs
Authors: Singh R.K.
Published: December 2018

A circular waveguide with axially periodic thin metal disc inserts for its potential application in a gyro-TWT has been investigated for dispersion, form factor, power flowing through the structure, interaction impedance, and gain. The structure has been field analysed for its dispersion characteristics with due care to include the rigour of considering the effect of higher order space and modal harmonics. Dispersion characteristics reveal that the structure under study has like band-pass characteristics. Effect of variation of structure parameters on the dispersion characteristics has been observed in order to shape the waveguide-mode curve for wideband operation of the device. With the help of form factor which decides the extent of coupling between beam and wave, optimum beam position has been decided where maximum interaction between beam and wave takes place. For the structure under study, the value of azimuthal interaction impedance increases with the introduction of metal discs in the waveguide except at higher frequencies, where it decreases rapidly to a value that is lower than that for a smooth-wall circular waveguide. Gain-frequency response observation shows that the dispersion characteristics are readily reflected in the gain-frequency response. It has been found that the disc-hole radius is more effective in controlling the device gain while it is disc-periodicity which is the most effective structure parameter in controlling the device bandwidth. Results have been verified against published results and found to be in very close agreement.

Authors: Rani Shweta , Singh A.P.
Published: December 2018

In this paper the proposed structure is based on a modified planar Koch curve antenna, whose geometrical parameters are determined by iterative function system algorithm for fractal curve generation. Compared with conventional antenna with same dimensions, modified Koch curve antenna provides additional frequency resonances. The asymmetrical ground plane has been optimized by means of bacterial foraging optimization (BFO) to make the proposed antenna feasible for wide band operation. In addition to miniaturization of about 40%, the optimized reference ground plane provides multi and ultra-wide band with high impedance matching throughout the frequency bands covering various wireless telemedicine applications. In order to assess the reliability of the antenna, measurements have been performed on the fabricated prototype and the obtained results shows good agreement with simulated results.
The analytical field expressions associated with lightning channel in presence of ground reflection at striking point
Authors: Izadi M. , Ab Kadir M.Z.A. , Hajikhani M.
Published: December 2018

In this paper a general set of field expressions associated with a lightning channel are proposed to evaluate the electromagnetic fields due to lightning in the presence of a ground reflection at the channel base. The ground reflection factor is due to the difference between the channel and ground impedances and can enter additional reflected currents into the lightning channel. The proposed field expressions can support the widely used current functions and current models directly in the time domain without the need to apply any extra conversions. Moreover, the proposed expressions are applied on a sample of lightning current that has been obtained from a triggered lightning experiment and the evaluated electromagnetic fields are compared to the corresponding measured fields and the results discussed accordingly. The results illustrate that the simulated fields based on the proposed method are in good agreement with the measured fields. Moreover, the ground reflection factor can have a great effect on the values of the lightning electromagnetic fields. The proposed field expressions consider all field components directly in the time domain and vary appropriately to join with widely used coupling models to evaluate the lightning induced voltage on power lines without the need to apply any extra conversions.

Published: December 2018

We propose a general global optimal algorithm to optimize the miniature permanent magnet structure of a micro magnetic resonance chip(μ NMR-chip). For this purpose, we analyze the sensitivity of the permanent magnet structure to the design variables and determine the optimization variables. After this, radial basis function neural networks(RBFNNs) are constructed to model the objective functions, and the nondominated sorting genetic algorithm II (NSGA II) is improved by introducing a different weighting factor for each objective function in calculating the crowding distance. Combining the RBFNN with the improved NSGA II optimizes the miniature permanent magnet structure. Through comparison, the optimization solutions are proven effective. Finally, the optimized permanent magnet structure is manufactured and tested experimentally. After optimization, the volume of the permanent magnet block is reduced by 39%, and the permanent magnet becomes easier to manufacture.

Pulsed Eddy Current Testing (PECT) is one of the advanced Electromagnetic Nondestructive Evaluation (ENDE) technology. In applications for crack detection and evaluation, rectangular probes are found superior to the cylindrical ones in terms of the directional characteristics and capability of creating uniform eddy current distributions. In this paper, in a bid to investigate the influence of parameters of a rectangular probe on inspection sensitivity and seek the optimal probe structure, a numerical model for conductivity/defect assessment with a rectangular probe is built up by using Comsol. Following this, experiments on flaw evaluation are undertaken by using the probe with the optimal parameters found in Finite Element Modelling (FEM). Through simulations and experiments, it can be seen that the rectangular probe with dimensions in the proportion of 2:1:1.5 (length:width:height) is optimal for conductivity evaluation.

A theoretical investigation has been carried out to analyze the transmission of electromagnetic field through a slab of quadric inhomogeneous chiral medium. The transmission coefficients at dielectric-chiral and chiral-dielectric interfaces are derived analytically. The transmitted electromagnetic field expressions have been obtained using Maslov's method. The derived analytical field expressions at caustic or focal point of quadratic inhomogeneous chiral slab have been solved numerically using MATHEMATICA. The result obtained using Maslov's method are compared with Hyugen Kirchhoff's integral which are in good agreement.

A dual resonant G shaped and U shaped metamaterial structure with dipole antenna is designed, fabricated on FR4 substrate and measured using Agilent network analyzer. The metamaterial based loading creates additional resonance, so this proposed antenna effectively covers both 2.4 GHz and 5.8 GHz bands. The return losses of the measured results are in agreement with simulated results, the measured S parameters and simulated radiation pattern showed that the proposed design is suitable for WLAN frequency regions. The measured return loss (S parameter) of G shaped metamaterial based dipole is−21.45 dB at 2.4 GHz and simulated return loss is −21.61 dB at 5.2 GHz. The measured return loss of U shaped metamaterial is −26.11 dB at 2.4 GHz and second simulated resonance frequency occurs at 5.8 GHz at the return loss value of −23.96 dB which is most suitable for wireless LAN application.
