“Good” or “Saint” Janibek Khan (1342–1357) in the Oral Historical Memory of the Nomads-Kazakhs
Authors:   Al-Farabi Kazakh National University, Erofeeva Irina V.
Published: March 2021

Research objectives: To identify the main reasons for the formation of the cult of Janibek Khan of the Golden Horde in the oral historical memory of the nomadic steppe tribes which was embodied in the narrative tradition of Kazakhs from the fifteenth to eighteenth century. Research materials: The texts of the Kazakh folklore sources from the last quarter of the eighteenth to the beginning of twentieth century, published in different genres (tales, epics, legends, fairy tales) and dedicated to Janibek Khan or characters of the oral narratives closely related to him. Results and novelty of the research: The historiography of the Golden Horde and the medieval history of Kazakhstan considers it conventional wisdom that Uzbek Khan (r. 1313–1342) played the decisive role in the Islamization of the tribal population of the Ulus of Jochi during the fourteenth century. However, none of the Kazakh folklore sources recorded from the last quarter of eighteenth to beginning of twentieth century mentions his name. Rather, this role is given to the son and successor of Uzbek, Janibek Khan, who is the most popular character of oral narratives of Kazakhs dedicated to the Eurasian Middle Ages. This fact leads to the conclusion that the innovative activities of Uzbek in the field of religion covered mainly the western part of the Ulus of Jochi but had a limited impact on the steppe nomads of the Eastern Dasht-i Kipchak. The main role in the spread of Islam and Islamic culture to the east of the Ural River valley, in the territory of the ethnic nomadic ancestors of the Kazakh tribes, was played by Janibek Khan, which was reflected in the popular historical consciousness of Kazakhs. This article demonstrates the influence of Sufism’s cult of the “saints” borrowed by Muslim communities of the steppe in the process of sacralization of the historical Janibek Khan in the Kazakh narrative tradition and highlights the most characteristic features of his mythologized image. The scholarly novelty consists in the statement of the abovementioned theme of research and the structural analysis of the revealed folklore texts, which allows one to solve the long-standing problem of the association of the folk literature Janibek Khan of the Golden Horde and the historical Kazakh Khan of the same name who ruled in the eastern part of the former Ulus of Jochi in the later period.
Accentology of the Takht Eli: The Great Horde or the Greater Horde?
Authors:   Institute of Russian History of the Russian Academy of Sciences, Trepavlov Vadim V.
Published: March 2021

Research objectives: The author makes an attempt to determine the correctness of the emphasis in the Russian name of the Khanate Taht Eli – Bol’shaya (Great) or Bol’shaya (Greater) Horde; to check the connection of this name with the Mongolian and Turkic designations of the Mongol Empire, the Golden Horde, and the Crimean Khanate. Research materials: Russian, Lithuanian, and Crimean diplomatic correspondence from the fifteenth to seventeenth centuries; Russian medieval chronicles and other works; works of European authors of the sixteenth century; Turkic, Mongolian, and Persian histo­rical works from the thirteenth to eighteenth centuries; Golden Horde yarlyqs; monuments of Tatar and Kazakh folklore, historiography of the problem under study. Results and novelty of the research: The author concludes that the designation “Great Horde” (Bol’shaya) existed in Russian speech of the fifteenth century. This conclusion has to be justified, since, firstly, it seemed obvious and therefore had never been argued in historiography. Secondly, it must be discussed due to the recently proposed variant pronunciation ‘Bol’shaya’ (Greater Horde). The analyzed Russian name of Takht eli was a translation of one of the versions of the official name of the Jochi Ulus and at the same time, it repeated the distorted name of the Mongol Empire. The possible origins of the Russian name of the Jochi Ulus, the ‘Golden Horde’, are also to be found within the imperial history of the Mongols.
On the Mutual Relations between the Kazakh Khanates and the Qing and Russian Empires. Book Review: Noda J., Onuma T. A Collection of Documents from the Kazakh Sultans to the Qing Dynasty
Authors:   National Institute of Technology, Oyama College, Nagamine Hiroyuki
Published: March 2021

This study, titled A Collection of Documents from the Kazakh Sultans to the Qing Dynasty, deals with 16 documents addressed from Kazakh sultans to the Qing Dynasty (and the Russian Empire/Governor-General of Siberia). These were written in the Oyirad (Mongol) language with Tod script or in the Turkic language with Arabic script from the eighteenth to nineteenth century, and come complete with text, transcription, and translation. In addition, this study includes two essays written by the authors who made use of these documents. The majority of Qing documents are preserved in a collection of the First Historical Archives (第一歴史襠案館) in Beijing. Many of these documents related to the Kazakhs have started to be published as The Collection of the Archival Documents Concerning Sino-Kazakh Relations at the Time of the Qing Dynasty (清代中哈関係襠案彙編) and so on, and to be used for historical research. Of the documents dealt with in this study, 14 are from the Manchu Language Reference Copy of Grand Council Palace Memorial (軍機処満文副奏摺) of the First Historical Archives, one is from Tsentral’nyi gosudarstvennyi arkhiv Respubliki Kazakhstan, and one is from Vneshnyaya politika Rossii XIX i nachala XX veka (Moskva: Izd-vo Nauka, t. 11–12, 1979–1980). However, most of these documents are not included in the published collection mentioned above. Therefore, this study, together with the above-mentioned collection, represents another major step in the study of these documentss. In addition, by utilizing these documents, Takahiro Onuma clarifies that the international world order between the Qing dynasty and Kazakh nomads in Central Asia was not based on the “suzerain-dependency (Ch. zong-fan 宗藩) relationship”, which was heavily influenced by Confucianism, but rather, on the “master-slave (Mon. ejen-albatu) relationship”, which originated in Mongol nomadic society. Jin Noda, who also utilized these documents, states that the title of Kazakh sultans, which has been regarded as a product of the Qing benefit policy, was in fact a result of both the Kazakh sultans and Qing requiring the ‘title-bestowal system’ in the process of the establishment of relations. This system was gradually becoming a mere formality, partly because of the influence of Russia. These findings suggest that the Kazakh khanates were independently developing a “bilateral diplomatic policy” while mediating between the Qing and Russian empires, and they highlight the policy differences of both empires toward the Kazakh khanates. We hope that the fin­dings from this study will further advance the study of the history of the mutual relations between the Kazakh khanates and the Qing and Russian empires.
Tatar Violence over Metropolitan Maxim and the Sack of Kiev in 1299: Causes, Circumstances, and Consequences of Events That “Did Not Happen”
Authors:   M.S. Hrushevsky Institute of Ukrainian Archeography and Source Studies of the National Academy of Sciences of Ukraine, Gaydenko Pavel I.
Published: March 2021

Research objectives: This article presents a critical analysis and deconstruction of historiographical ideas about the reasons for Kiev Metropolitan Maxim’s move to Vladimir. Much attention is paid to comparing the prevailing opinions in Russian scholarship with the data of ancient Russian sources and archaeology. The most plausible reasons and motives that prompted the Russian hierarch to change his place of residence are exa­mined, and the circumstances of the metropolitan’s relocation are substantially clarified. Research materials: Old Russian sources and Russian historiography. Results and novelty of the research: The prevailing view for the reasons and circumstances behind the move of Metropolitan Maxim to Vladimir, an even described in Russian church historiography, is based on the erroneous opinion of Prof. E.E. Golubinsky. The source data and the sequence of events allow us to conclude that the metropolitan’s move was a well-planned action designed to solve many problems. Following the death of Nogai, and in the face of the growing political ambitions of the Galicia-Volyn princes, Byzantium tried to draw closer to Sarai. In Kiev, the inhabitants feared the attacks of disparate Tatar detachments, but were most afraid of being at the epicenter of the war between the Horde, Lithuania, and Galich over Kiev. Relations between the metropolitans and the South Russian episcopate remained extremely difficult. Under such conditions, the move of the Metropolitan to Vladimir became a logical and well-thought-out response.
Toward the History of Tatars of Inner Asia: An Attempt to Identify Tribal Names
Authors:   Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the Russian Academy of Sciences, Nanzatov Bair Z. , Tishin Vladimir V. ,   Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the Russian Academy of Sciences
Published: March 2021

Research objectives: This article attempts to correlate the names of the tribes of the Tatars mentioned in both the “Secret History of the Mongols” and Rashīd ad-Dīn al-Ṭabīb’s “Jāmī al-Tawārīkh”. Also, it contains separate remarks regarding the localization of certain tribal groups and later historical population groups among the Turkic and Mongol peoples, which could have a historical connection with the considered groups. At one time, P. Pelliot conducted similar work in his exhaustive study. Since then, the extension of the source base allows one to offer some adjustments of the reconstructions undertaken by him and other researchers. Research materials: The authors relied on two main sources: the Mongolian chronicle of the thirteenth century, the “Secret History of the Mongols”, and the composition of the early fourteenth century “Jāmī al-Tawārīkh”, recognized as a work of Rashīd ad-Dīn al-Ṭabīb. The “Altan Tobchi” was also used as auxiliary source, being a Mongol chronicle of the seventeenth century that essentially repeats the content of the “Secret History” in the studied fragments. In some cases, the authors turned to various Turkic texts and Chinese sources. Linguistic data offered from the known information about the languages used, as well as the ethnonymy and onomastics of the Mongolian and Turkic peoples, were used for phonetic reconstructions. Ethnographic materials were also used to a certain extent. Research results and novelty: Based on the data of Rashīd ad-Dīn al-Ṭabīb about the six tribes of the Tatars of Inner Asia, evidenced by a recently discovered document of the Yuan epoch, the authors compared the names given by the “Secret History of the Mongols” and “Jāmī al-Tawārīkh”, then involved the use of an additional source, and as a result reconstructed the names of Totoqli’ut, Alči, Čaγa’an, Küyin, Täräät / *Täräit, leaving the name *Barquy as debatable. For a number of ethnonyms, a broad justification of semantics is proposed. However, not all of them are subject to a single formation system, which is demonstrated in the text of the article.
Western Immigration in the fourteenth-century Golden Horde: The Case of Venetian Tana
Authors:   Santa Reparata International School of Art, Pubblici Lorenzo
Published: March 2021

Objective: This paper’s aim is to reconstruct the Western population of Venetian Tana in the fourteenth century, the residents’ perception of their condition as “mig­rants”, and finally this population’s interactions with the other communities who lived there. Research materials: The sources used are primarily the notarial deeds of the Venice State Archive together with the vast and excellent scholarship produced in recent decades. Research results and novelty: For over two centuries the settlement of Tana, situated in the territory of the Golden Horde, represented the easternmost outpost of the Latin emporia in the Levant. Here, the utilitarian concept of the Western urban mercantile class found itself confronted with a new experience. This group was a minority living in close contact with larger, cohesive communities whose cultural background was extremely diverse. Those who emigrated east were mainly the emerging urban bourgeoisie, but also families of ancient noble origin who had nothing in common with the world of the Steppe and its traditional roots. These citizens came to the Levant, bringing with them the urban associative model. The life of the settlement at the mouth of the river Don is an ideal basis for observing the flow of people who left Venice and its surroundings on galleys and, after months of travel, arrived on the shores of the Sea of Azov.

Novel predictors of airway hyperresponsiveness in children with respiratory symptoms without obstructive pattern
Authors: Reinsberg Max , Siebert Stephanie , Dreher Charlotte , Bogs Thomas , Ganschow Rainer , Yavuz S. Tolga
Published: March 2021

Background: Methacholine challenge (MCC) is the most common method to
detect airway hyperresponsiveness (AHR). Although MCC is accepted as
safe diagnostic tool, it is time consuming and could be exhausting for
patients. Thus, it might be helpful to identify predictive factors for
AHR. We aimed to develop a diagnostic tool for predicting AHR in
children with respiratory symptoms without obstructive pattern. Methods:
Data from children who had undergone MCC were analyzed retrospectively.
The demographic features of patients along with laboratory results were
collected. Results: A total of 123 children with a median age of 10.5
years were enrolled. AHR was detected in 81 children (65.8%). The age
of the children with AHR was significantly younger. The prevalences of
aeroallergen sensitization, nocturnal cough, wheezing and a baseline
forced expiratory flow at 75% of vital capacity (FEF75) <65%
were significantly more frequent in children with AHR. Multivariate
logistic regression analysis revealed age, ever wheezing, nocturnal
cough, tree pollen allergy and FEF75<65% as independent
predictors of the AHR. A weighted clinical risk score was developed
(range, 0-75 points). At a cutoff point of 35 the presence of AHR is
predicted with a specificity of 90.5% and a positive predictive value
(PPV) of 91.5%. Conclusion: In children suspected of having asthma, but
without an obstructive pattern, combining independent predictors, which
can be easily obtained in clinical practice, in a novel prediction rule
might be used to identify children with AHR.
Engineering a Better IT Program Manager: A Comparative Study of IT PM Education and Training
Authors: Parker William
Published: March 2021

This article examines the relationship between Department of Defense information technology (IT) program managers (PMs), their technical education, commercial project management certification, and project management success—also known as project efficiency—for IT PMs. The researcher asked, “To what extent does project management success in scope, schedule, and cost compare among PMs, specifically their technical education, commercial project management certification, and interaction effects between education type and commercial PM certification?” A gap in research exists on whether IT PMs with a technical education positively or negatively impact project outcomes. The IT PM community needs more studies on the extent to which commercial PM certifications affect project efficiency. The researcher used factorial multivariate analysis of variance (MANOVA) to compare education and PM certification to project efficiency. MANOVA provided for the examination of the interactive effects. A Mann-Whitney post hoc test confirmed the MANOVA results. Both tests concluded that no relationship exists between undergraduate technical degree, commercial PM certification, and project management success.
The effects of EU R&I funding on SME innovation and business performance in new EU member states: Firm-level evidence
Authors: Cuckovic Nevenka , Vuckovic Valentina
Published: March 2021

SMEs are the most dynamic and vibrant part of the enterprise sector in terms
of start-ups and new jobs, and a significant share of the EU?s total
innovation activities take place within them. This paper uses the Community
Innovation Survey (CIS) 2014 and eCORDA data to analyse whether SME
participation in EU research and innovation (R&I) funding programmes has
increased their innovation activities and business performance. To achieve
this, we empirically test whether SMEs that received EU funds recorded an
improvement in their innovation and economic performance. This is measured
by research and development (R&D) expenditure, product innovation, turnover,
and employment. The paper focusses particularly on new EU member countries
and among them to those from Central and Eastern Europe (CEE). It explores
the theoretical and methodological backgrounds that guided us in these
analyses and performs treatment effect analysis at firm level, using CIS
CDROM data that we received on request from Eurostat. The obtained results
indicate that EU R&I funding is beneficial to the innovation activities of
SME recipients, and to their overall business performance. It also assists
new EU member states in the process of ?catching up? to the growth levels of
more established EU economies.
Employee reactions to crossborder acquisitions: Evidence from an acquired Serbian company
Authors: Savovic Sladjana
Published: March 2021

The purpose of this paper is to examine factors influencing employee
reactions to changes brought about by crossborder acquisitions. The research
was conducted in a company operating in Serbia?s retail sector that was
acquired by a Belgian multinational company. The data were collected from
344 respondents. Measures of central tendency, the Mann-Whitney U test, and
regression analysis were used to test the research hypotheses. The research
results show that employee reactions to changes brought by cross-border
acquisition were generally positive. The study show that corporate cultural
differences between the acquiring company and the acquired company and the
support of transformational leaders resulted in employees reacting
positively to the changes. The study attempts to improve understanding of
employee reactions during the process of change occurring as a result of
cross-border acquisition. Additionally, this study has practical
implications, as it points to how the appropriate management of human
resources contributes to positive employee reactions.
The correlation between stock returns before and after analyst recommendation revisions
Authors: Kudryavtsev Andrey
Published: March 2021

In this study I analyse the correlation between stock returns before and
after analyst recommendation revisions. I hypothesise that if a
recommendation revision for a given stock takes place after a short period
when the stock?s price moves in the opposite direction, it may indicate that
the fundamentals that caused the analyst to revise their recommendation are
less completely (if at all) incorporated in the stock price, significantly
increasing the probability of subsequent post-event price drift. Analysing a
large sample of recommendation revisions, I document that both
recommendation upgrades and downgrades are followed by significant
one-tosix-month price drifts (reversals) if they are preceded by the
opposite-sign (same-sign) short-term cumulative abnormal returns. The effect
remains significant after accounting for additional relevant company specific
(size, Market Model beta, historical volatility) and event-specific (stock?s
return and trading volume on the event day, brokerage firm size, analyst
experience, recommendation category before the revision, number of
categories changed in the revision) factors.
The role of foreign banks in the transmission of monetary policy: Empirical evidence from Tunisia
Authors: Gassouma Mohamed , Ben-Ahmed Kais
Published: March 2021

This paper presents an empirical analysis of the effect of monetary policy
shocks on credit supply in Tunisia, using a vector autoregressive model and
a nonlinear interactive model. The focus is on the magnitude of these shocks
in the presence of foreign banks. The variables of interest are the
concentration index of deposit banks, and monetary policy shocks based on
the monthly data of 27 universal and business banks covering the period 1993
to 2016. The results support a positive and significant impact of
concentration index on credit supply. However, monetary policy shocks appear
to have no significant effect when the market is concentrated with the entry
of foreign banks. The findings of this study also reveal that the entry of
foreign banks neutralises monetary policy shock transmission in the credit
supply, which may be offset by market discipline.
Covering properties of Cp(X) and Ck(X)

Published: March 2021

Let X be a Tychonoff space. We survey some classic and recent results that
characterize the topology or cardinality of X when Cp (X) or Ck (X) is
covered by certain families of sets (sequences, resolutions,
closure-preserving coverings, compact coverings ordered by a second
countable space) which swallow or not some classes of sets (compact sets,
functionally bounded sets, pointwise bounded sets) in C(X).
A new young type inequality involving Heinz mean

Published: March 2021

In this paper, we gave a new Young type inequality and the relevant Heinz
mean inequality. Furthermore, we also improved some inequalities with
Kantorovich constant or Specht?s ratio. Meanwhile, on the base of our
scalars results, we obtain some new corresponding operator inequalities and
matrix versions including Hilbert-Schmidt norm, unitarily invariant norm and
related trace versions, which can be regarded as the application of our
scalar results.
Convergence and stability of an iterative algorithm for strongly accretive Lipschitzian operator with applications
Authors: Kumar Vivek , Hussain Nawab , Khan Abdul , Gürsoy Faik
Published: March 2021

Using different technique and weaker restrictions on parameters, convergence
and stability results of an SP iterative algorithm with errors for a
strongly accretive Lipschitzian operator on a Banach space are established.
Validity of new convergence results is verified through numerical examples
and convergence comparison of various iterative algorithms is depicted. As
applications of our convergence result, we solve a nonlinear operator
equation and a variational inclusion problem. Our results are refinement and
generalization of many classical results.
Ordering of the unicyclic signed graphs with perfect matchings by their minimal energies
Authors: Yuan Ling , Wang Wen-Huan
Published: March 2021

Let U?2n be the set of unicyclic signed graphs with perfect matchings
having 2n vertices, where ? is a signing function from the edge set of the
graphs considered to {-1,1}. The increasing order of the signed graphs
among U?2n according to their minimal energies is considered. A
relationship between the energies of a unicyclic graph and of its signed
graphs is derived. A new integral formula for comparing the energies of two
signed graph is introduced. In U?2n with n ? 721, the first 18 signed graphs
in the increasing order by their minimal energies are obtained.
Hemi-slant ξ⊥-Riemannian submersions in contact geometry

Published: March 2021

M. A. Akyol and R. Sar? [On semi-slant ??-Riemannian submersions, Mediterr.
J. Math. 14(6) (2017) 234.] defined semi-slant ??-Riemannian submersions
from Sasakian manifolds onto Riemannian manifolds. As a generalization of
the above notion and natural generalization of anti-invariant ??-Riemannian
submersions, semi-invariant ??-Riemannian submersions and slant
submersions, we study hemi-slant ??-Riemannian submersions from Sasakian
manifolds onto Riemannian manifolds. We obtain the geometry of foliations,
give some examples and find necessary and sufficient condition for the base
manifold to be a locally product manifold. Moreover, we obtain some
curvature relations from Sasakian space forms between the total space, the
base space and the fibres.
Function spaces based on L-sets

Published: March 2021

For a commutative, integral, and divisible quantale L, a concept of top
L-convergence spaces based on L-sets other than crisp sets is proposed by
using a kind of L-filters, namely limited L-filters defined in the paper.
Our main result is the existence of function spaces in the the concrete
category of top L-convergence spaces over the slice category Set#L rather
than the category Set of sets, such that the concrete category of top
L-convergence spaces over the slice category Set#L is Cartesian closed. In
order to support the existence of top L-convergence spaces, some nontrivial
examples of limited L-filters and top L-convergence spaces are presented
also.
The order of convergence of an optimal quadrature formula with derivative in the space W(2,1)2
Authors: Hayotov A.R. , Rasulov R.G.
Published: March 2021

The present work is devoted to extension of the trapezoidal rule in the
space W(2,1)2. The optimal quadrature formula is obtained by minimizing the
error of the formula by coefficients at values of the first derivative of an
integrand. Using the discrete analog of the operator d2/dx2-1 the
explicit formulas for the coefficients of the optimal quadrature formula are
obtained. Furthermore, it is proved that the obtained quadrature formula is
exact for any function of the set F = span{1,x,ex,e-x}. Finally, in the
space W(2,1) 2 the square of the norm of the error functional of the
constructed quadrature formula is calculated. It is shown that the error of
the obtained optimal quadrature formula is less than the error of the
Euler-Maclaurin quadrature formula on the space L(2)2 .
WHENCE THE DEMAND FOR ETHICAL THEORY?
Authors: Cueni Damian , Queloz Matthieu
Published: March 2021

Where does the impetus towards ethical theory come from? What drives humans to make values explicit, consistent, and discursively justifiable? This paper situates the demand for ethical theory in human life by identifying the practical needs that give rise to it. Such a practical derivation puts the demand in its place: while finding a home for it in the public decision-making of modern societies, our account also imposes limitations on the demand by presenting it as scalable and context-sensitive. This differentiates strong forms of the demand calling for theory from weaker forms calling for less, and contexts where it has a place from contexts where it is out of place. In light of this, subjecting personal deliberation to the demand turns out to involve a trade-off.
B4C ve Al2O3 Seramik Plakaların Mekanik ve Balistik Özelliklerinin İncelenmesi
Authors: (GÜNGÖR) KOC Serap
Published: March 2021

Bilinen en sert malzemelerden olan bor karbür (B4C) ve alümina seramik (Al2O3) plakaların eşsiz özelliklerinden dolayı dikkatleri çekmektedir. Bu çalışmada balistik koruma amaçlı kullanılan bor karbür (B4C) ve alümina (Al2O3) seramik plakaların iç yapı, mekanik ve balistik özellikleri incelenmiş ve literatürde yapılmış olunan benzer çalışmalarla sonuçları karşılaştırılmıştır. B4C ve Al2O3 içeriği homojen bir dağılım göstermekte olup sırası ile yoğunlukları 2.52 g/cm3 ve 3.85 g/cm3 olarak ölçülmüştür. B4C ve Al2O3 numuneleri gevrek kırılma özelliği sergilemekte ve düşük gerilimlerde lineer deformasyon oluşturmaktadır. Elastik özellikler bor karbür içeriğindeki karbon oranına göre değişmektedir. Bor karbür plakanın elastisite modülü 440 GPa olarak elde edilmiştir. B4C ve Al2O3 plakalar, askeri standartlara uygun olarak yapılan balistik testlerde IV. seviye tehditlere (hızı bor karbür plakasında 878 m/sn, alümina plakasında 884 m/sn olan 7.62x51 mm M2 AP mermide) karşı travma derinlikleri 28.8 mm ve 34.4 mm olmak üzere NIJ-STD-0101.07 standardı çerçevesinde tam koruma sağlamaktadır. B4C’nin yüksek sertliği nedeniyle Al2O3’e nazaran daha iyi balistik özellik göstereceği beklentisi, malzemenin aşırı gevrek olması nedeniyle mümkün olmamaktadır.
EEG, EMG and ECG based Determination of Psychosocial Risk Levels in Teachers based on Wavelet Extreme Learning Machine Autoencoders
Authors: ŞENGÜR Dönüş
Published: March 2021

Teachers who perform a sacred work are faced with many psychosocial risks. These risks can often be caused by the school administration, the students, and environmental factors. Machine learning and data mining approaches have recently gained much attention in social and educational researches. In this study, a novel approach, which is based on data augmentation and data classification, is proposed for the prediction of the psychosocial risk levels of the teachers. The data augmentation is carried out by using an extreme learning machine autoencoders (ELM-AE). More specifically, the wavelet activation function is incorporated into the ELM-AE to develop a novel approach called WELM-AE. After data augmentation, a traditional ELM classifier is used in the prediction of the psychosocial risk levels of teachers. A dataset, which contains physiological factors, namely Electrocardiography (ECG), Electromyography (EMG), and Electroencephalography (EEG), is used to evaluate the performance of the proposed method. Classification accuracy is used as the evaluation metric. All coding is carried out in MATLAB, and a 99.9% accuracy score is obtained with the proposed method. A performance comparison is also carried out with some machine learning techniques, namely decision trees (DT), support vector machines (SVM), and K-nearest neighbour (KNN). The results show that the proposed WELM-AE and ELM classifier outperform the compared methods.
Comparison of Ceramic and Coated Carbide Inserts Performance in Finish Turning of Hardened AISI 420 Stainless Steel
Authors: RAFİGHİ Mohammad
Published: March 2021

Martensitic stainless steels have a high carbon amount that can be heat treated to increase their hardness. There are widely used in cutlery, needle valves, shear blades, dental and surgical equipment. In this study finish hard turning was performed on the AISI 420 stainless steel using ceramic and coated carbide inserts under dry cutting conditions. Depth of cut, feed rate, and cutting speed were selected as machining parameters, while surface roughness was chosen as machinability criterion. Taguchi L9 orthogonal array was selected for the design of the experiment to decrease the number of trials for reducing time and cost of manufacturing. The response surface methodology was utilized for determining a relationship among process parameters and output parameter. The analysis of variance results indicates that feed rate is the utmost factor on the surface roughness for both ceramic and carbide inserts with 86.56% and 80.57% contribution, respectively. The developed mathematical models for ceramic and coated carbide inserts are capable to predict surface roughness with 97.07% and 96.13% accuracy, respectively. Based on the desirability function and response optimizer of the RSM, 0.2 mm depth of cut, 250 m/min cutting speed, and 0.05 mm/rev feed rate were selected as optimum machining factors. Finally, the mean surface roughness for ceramic and coated carbide inserts calculated as 0.57 µm and 0.71 µm, respectively. Therefore, the ceramic insert exhibited better performance compared to the coated carbide insert.
Art and Design Practices as a Driver for Deformable Controls, Textures and Screen Interactions
Authors:   , Steer Cameron
Published: March 2021

In this thesis, we demonstrate the innovative uses of deformable interfaces to help de-velop future digital art and design interactions. The great beneﬁts of advancing digital art can often come at a cost of tactile feeling and physical expression, while traditional methods celebrate the diverse sets of physical tools and materials. We identiﬁed these sets of tools and materials to inform the development of new art and design interfaces that offer rich physical mediums for digital artist and designers. In order to bring forth these unique inter-actions, we draw on the latest advances in deformable interface technology. Therefore, our research contributes a set of understandings about how deformable interfaces can be har-nessed for art and design interfaces. We identify and discuss the following contributions: insights into tangible and digital practices of artists and designers; prototypes to probe the beneﬁts and possibilities of deformable displays and materials in support of digital-physical art and design, user-centred evaluations of these prototypes to inform future developments, and broader insights into the deformable interface research.Each chapter of this thesis investigates a speciﬁc element of art and design, alongside an aspect of deformable interfaces resulting in a new prototype. We begin the thesis by studying the use of physical actuation to simulate artist tools in deformable surfaces. In this chapter, our evaluations highlight the merits of improved user experiences and insights into eyes-free interactions. We then turn to explore deformable textures. Driven by the tactile feeling of mixing paints, we present a gel-based interface that is capable of simulating the feeling of paints on the back of mobile devices. Our evaluations showed how artists endorsed the interactions and held potential for digital oil painting.Our ﬁnal chapter presents research conducted with digital designers. We explore their colour picking processes and developed a digital version of physical swatches using a mod-ular screen system. This use of tangible proxies in digital-based processes brought a level of playfulness and held potential to support collaborative workﬂows across disciplines. To conclude, we share how our outcomes from these studies could help shape the broader space of art and design interactions and deformable interface research. We suggest future work and directions based on our ﬁndings.

The curing system for newly developed solid state fire safe epoxy resins using dicyandiamide (DICY) was introduced. Composites of epoxy resins obtained from diglycidyl ether of 1,1-dichloro-2,2bis(4-hydroxyphenyl)ethylene bisphenol-C (BPC) and bisphenol-A (BPA) epoxy resins in the reaction with BPC and BPA and DICY hardener were studied. Solid epoxy resins were synthesised by the use of two different heating methods: conventional and microwave reactor. The quantities of DICY additions were 0.5–5.0 %, optimum was found to be 3 %. Limited oxygen index (OI) tests for different epoxy resins and addition of flame – retardants were carried out. The highest value of OI was 34.6. As additional flame-retardants were used zinc stannates (ZS, ZHS). Evident OI increase was noted from 27.0 for classical epoxies, 34.6 for BPC cured epoxies and 44 for cured composites with the addition of Zn/Sn flame-retardants.

Realism and Naturalism in Samrat Upadhyay’s The Guru of Love
Authors: Shrivastwa Bimal Kishore
Published: March 2021

This research project seeks to explore realism and naturalism in Samrat Upadhyay's novel, The Guru of Love, in the context of Nepalese society. It analyses how the novel delineates a realistic account of Nepalese middle-class people's hardships, struggles, and problems they face internally and externally through the character of Ramchandra, the protagonist of the fiction, an ordinary mathematics teacher who faces some hindrances in search of a better life and developing a career in the capital city. The principal objective of the study is to find the realistic, naturalistic, and materialistic elements in the novel, to examine the psychic predispositions that characters come through realistically, and to analyze the role of love and sex in terms of spirituality and emancipation as they all fall into the parameters of naturalism and realism. This study is developed through a theoretical framework based on realism and naturalism for the close textual analysis of the novel. The principal finding of the research paper is that the major characters of the novel, The Guru of Love, suffer from the conflict between their desires and their socio-economic realities. The article also surveys how material prosperity fails to resolve all the problems that human being goes through. It is expected that the paper stands as a reference for the research scholars interested to explore in the area.
The World Literature and Women’s Voice in Toni Morrison’s The Bluest Eye (1970) and Han Kang’s The Vegetarian (2007)
Authors: Widyaningrum Indiwara Pandu
Published: March 2021

This study seeks to investigate the women’s voice in the world literature depicted by ethnic female authors from African-American and Korean descent. Gaining international recognition in the world literature, Toni Morrison’s The Bluest Eyes (1970) and Han Kang’s The Vegetarian (2007) reveal different social-cultural conditions about how women are presented in their respective nation. Morrison presents the life of colored women struggling with racial discrimination in the predominant white society. Meanwhile, Kang employs the symbolic food of meat and vegetarianism to reveal the women’s voice against social conformity. Applying écriture feminine or women’s writing in the analysis, both Toni Morrison and Han Kang scrutinize the stereotypical representation of women as passive, obedient, and lacking. In examining the two works, some steps were done: 1) having close reading towards the text to analyze the representation of women; 2) doing the socio-cultural analysis in connection to the women’s voice; 3) drawing the conclusion about the significance of world literature to the women’s voice. This study finds that the world literature has its significant contribution as the windows for global readers to understand women’s issues portrayed in two different nations. Not only to present women’s voice, ethnic female authors such as Toni Morrison and Han Kang indeed share the local culture through their novels. With this condition, the world literature enables to break the barriers of male Western authors as the center by offering room for female writers from non-Western countries.
