The Safavid fraternity: shiism or sufism? Historiographical review of the Western European researchers' works
Authors: Akhundova N. F.
Published: October 2020

This article offers a detailed analysis of the religious and ideological foundations of the Safavid dynasty. It is based upon the modern predominantly Western European historiography. The methodological basis is the comparative analysis. Along with the works of British, French, German, Turkish, Russian and other scholars the author also uses medieval texts written in original (Oriental) languages. These are court chroniclers from the 16th-17thcent. by Fazl al-lah Ruzbikhan Khundji (Tarih-e alamara-ye Amini) and Iskender bek Turkman Munshi (Tarih-e alamara-ye Abbasi) and others. The Safavid dynasty was at the same time a dynasty of sheikhs and shahs. Therefore, the concepts of Sunnite teachings, Shi'ism and Sufism constitute an integral part of its culture and history. The article supplies a reader with the information necessary for establishing the religious views of each of the representatives of the Sufi House ofSafaviye, starting from the founder of the Sufi Order and ending with his heirs, the rulers of the Safavid state. The author elaborates the topic regarding the original denomination of Islam the Safavids embraced - Sunni or Shi'a. Subsequently she deals with the exact period of the Safavid transition from one Islamic denomination to another. Special attention is also paid to some aspects of the development of Sufi traditions and ideology at various stages of the history of the Safavid dynasty.
Ancient Egyptian - Arabic contacts in lexicon: clue to Arabic Urheimat?
Authors: Militarev A. Yu.
Published: October 2020

The present paper aims at demonstrating possibilities of the comparative and historical method in linguistics in reconstructing ethno-cultural prehistory of ancient peoples. Methodologically, it is based upon the analysis of 46 Ancient Egyptian-Arabic lexical parallels most of which are unattested in other Semitic and Afrasian languages, collected by the Hungarian specialist in Egyptian and Aftrasian languages G. Takacs and his predecessors. The author was the first to notice that some of 46 lexical parallels for semantic or phonetic reasons can hardly be considered to be randomly surviving cognates; neither can they be descarded as lookalikes. He suggests that they are direct lexical borrowings. This suggestion implies undiscovered contacts between Egypt and proto-Arabic speakers. According to the author's glottochronological dating, proto-Arabic separated from Central Semitic in early 3rdmill. BCE. These contacts started as early as the Old Kingdom and lasted through Middle to New Kingdoms. He concludes that the striking feature in this discovery is not only presumed Egyptian loans in Arabic but a small minority of very likely Arabisms in Egyptian language of all these periods. He argues that the most “robust” cases may testify to the Urheimat of proto-Arabic speakers located within reach of Egypt. The author is also inclined to identify the people of Midianites mentioned in both Hebrew and Arabic sources as Proto-Arabic speakers. However, as his competence is limited to comparative Afrasian linguistics and Semitic etymology, he leaves this arguable question to discuss archaeologists and historians.

Numerical investigation on the tunneling and mining induced geo-hazards: Case study in Quang Ninh, Vietnam
Authors: Giang Nguyen Cong , Manh Nguyen Van , Phich Nguyen Quang
Published: October 2020

In the field of rock mechanics, underground construction and mining, there have been many proposed methods for studying geo-hazards and also many research results that have been published in the world. In Vietnam, the numerical method is mainly used for analysis and design but not going deeply to predict the possible causes that lead to geo-hazards due to complex geological conditions. On the other hand, underground constructions and exploitation projects are often designed based on standards, regulations and experiences. The physical mechanism as well as the possibility of geo-hazards occurred when constructing underground structures and mining can take on various forms, depending on geological conditions and construction technology. Therefore, using numerical methods to simulate and analyze the possible geo-hazards is essential. This article presents a number of specific analysis cases, taking into account geological conditions and boundary conditions, and from that, raising a number of issues to note when using numerical methods.

Characterization of strain amplitude-dependent behavior of hardness and indentation size effect of SS400 structural steel
Authors: Vinh Nguyen Ngoc , Anh Vu Quoc , Thang Hong Tien
Published: October 2020

In this paper, the continuous stiffness measurement (CSM) indentation is employed to investigate fatigue mechanical properties of structural steel under cyclic loading. For this purpose, several representative analytical approaches were introduced to estimate the basic mechanical properties including Young’s modulus and indentation hardness from the characteristics of the loading/unloading curves. Several experiments including CSM nanoindentation, low-cycle fatigue experiment for four strain amplitude levels, optical microscope (OM), and transmission electron microscopy (TEM) examinations were conducted to observe the variation characteristics of mechanical properties at the microscale and their micro-mechanisms. The microstructural evolution of the specimens deformed by the low-cycle fatigue was observed using the OM and TEM examinations. The standard nanoindentation experiments were then performed at different strain rate levels to characterize the influences of strain rate indentation on hardness of the material. The micro-mechanisms established based on the microstructural evolution and strain gradient plasticity theory were introduced to be responsible for the variation of indentation hardness under cyclic loading. Finally, the indentation size effect (ISE) phenomenon in SS400 structural steel was investigated and explained through the strain gradient plasticity theory regarding geometrically necessary dislocations underneath the indenter tip. The experimental results can be used for practical designs as well as for understanding the fatigue behavior of SS400 structural steel.

Influence of fiber size on mechanical properties of strain-hardening fiber-reinforced concrete
Authors: Nguyen Duy-Liem , Nguyen Thac-Quang , Nguyen Huynh-Tan-Tai
Published: October 2020

This research deals with the influences of macro, meso and micro steel-smooth fibers on tensile and compressive properties of strain-hardening fiber-reinforced concretes (SFCs). The different sizes, indicated by length/diameter ratio, of steel-smooth fiber added in plain matrix (Pl) were as follows: 30/0.3 for the macro (Ma), 19/0.2 for the meso (Me) and 13/0.2 for the micro fiber (Mi). All SFCs were used the same fiber volume fraction of 1.5%. The compressive specimen was cylinder-shaped with diameter × height of 150 × 200 mm, the tensile specimen was bell-shaped with effective dimensions of 25 × 50 × 100 mm (thickness × width × gauge length). Although the adding fibers in plain matrix of SFCs produced the tensile strain-hardening behaviors accompanied by multiple micro-cracks, the significances in enhancing different mechanical properties of the SFCs were different. Firstly, under both tension and compression, the macro fibers produced the best performance in terms of strength, strain capacity and toughness whereas the micro produced the worst of them. Secondly, the adding fibers in plain matrix produced more favorable influences on tensile properties than compressive properties. Thirdly, the most sensitive parameter was observed to be the tensile toughness. Finally, the correlation between tensile strength and compressive strength of the studied SFCs were also reported.

Effects of bending stiffness and support excitation of the cable on cable rain-wind induced inclined vibration
Authors: Truong Viet-Hung
Published: October 2020

The main objective of this paper is to investigate the responses of the inclined cable due to rain-wind induced vibration (RWIV) considering the bending stiffness and support excitation of the cable. The single-degree-of-freedom (SDOF) model is employed to determine the aerodynamic forces. The 3D model of a cable subjected to RWIV is developed using the linear theory of the cable oscillation and the central difference algorithm in which the influences of wind speed change according to the height above the ground, bending stiffness, and support excitation of the cable are considered. The numerical results showed that the cable displacement calculated by considering cable bending stiffness in RWIV is slightly smaller than in the case of neglecting it. And, the cable diameter had a nonlinear relationship with cable displacement, where when both diameter and mass per unit length of cable increase cable displacement will decrease. In addition, the periodic oscillation of cable supports extremely increases the amplitude of RWIV if its frequency is nearby that of the cable.

Authors: Chính Nguyễn Văn , Thuật Đặng Công
Published: October 2020

Bài báo trình bày kết quả nghiên cứu thực nghiệm ảnh hưởng của tro bay, silicafume và môi trường dưỡng hộ đến cường độ chịu nén của bê tông. Trong đó, xi măng được thay thế bởi tro bay và silicafume lần lượt theo các tỉ lệ khác nhau tối đa 20%. Các mẫu bê tông được dưỡng hộ trong hai môi trường không khí và nước. Tiến hành khảo sát độ sụt, khối lượng thể tích và cường độ chịu nén của bê tông trong thời gian 90 ngày, kết quả chỉ ra rằng tro bay làm tăng trong khi silicafume làm giảm độ sụt của hỗn hợp bê tông. Ngoài ra silicafume còn góp phần giảm khối lượng thể tích của bê tông. Trong cả hai môi trường dưỡng hộ thì 20% xi măng được thay thế bởi tro bay và silicafume giảm cường độ chịu nén của bê tông và đạt tối đa 93% cường độ chịu nén so với mẫu đối chứng tại 90 ngày, trong khi đó 5% silicafume làm tăng cường độ chịu nén của bê tông. Cường độ chịu nén của bê tông có và không có tro bay hay silicafume thay thế xi măng khi được dưỡng hộ trong nước lớn hơn so với các mẫu bê tông tương ứng dưỡng hộ trong môi trường không khí, tỉ lệ cường độ giữa hai môi trường dưỡng hộ dao động trong khoảng từ 1,2 đến 1,7. Sai lệch lớn nhất về cường độ chịu nén giữa hai môi trường dưỡng hộ là khi sử dụng 20% tro bay để thay thế xi măng, trong khi đó sự khác biệt là nhỏ nhất khi 10% silicafume được sử dụng để thay thế xi măng.

Từ khóa:

Authors: Chỉnh Vũ Đan
Published: October 2020

Bổ sung thêm giếng khoan cho các giàn khoan đầu giếng là một yêu cầu thường gặp khi các giếng hiện hữu đã hết dần trữ lượng sau một thời gian khai thác. Đặc biệt ở Việt Nam hiện nay, một số lượng lớn các giàn đã chuyển sang giai đoạn khai thác thứ cấp. Mặt khác do giá dầu sụt giảm, hiệu quả đầu tư giàn mới là không cao, nên nhu cầu nâng cấp giàn và bổ sung thêm giếng khoan là vấn đề tất yếu. Một số phương án bổ sung thêm giếng khoan cho các giàn đang được áp dụng phổ biến trên thế giới hiện nay bao gồm: Bổ sung các giếng đơn (single well) trong các ống dẫn hướng (conductor), bổ sung các giếng đôi (dual well) trong từng ống dẫn hướng, bổ sung các giếng đơn trong cụm ống dẫn hướng tự đứng độc lập. Mỗi phương án đều có mức độ ảnh hưởng khác nhau đến độ bền kết cấu giàn hiện hữu, chi phối chung đến tính khả thi và hiệu quả mở rộng khai thác của giàn tùy từng điều kiện cụ thể. Bài báo đề xuất các tiêu chí để phân tích, đánh giá ảnh hưởng của các phương án bổ sung đầu giếng đến độ bền kết cấu theo quy định của các tiêu chuẩn hiện hành. Các tiêu chí này được áp dụng để đánh giá và lựa chọn phương án bổ sung giếng cho giàn JVPC WHP-C1 đang khai thác ở mỏ Rạng Đông của Việt Nam. Kết quả nghiên cứu của bài báo có thể sử dụng làm tài liệu tham khảo cho các dự án tương tự trong điều kiện Việt Nam.

Niglá: Methodology of Discontinuous (Im)Mobilities among Malian Kel Tamasheq in Bamako
Authors: Gonzales Giulia
Published: October 2020

This article analyses the research methods adopted while working with Kel Tamasheq (Tuareg) families in the urban space of Bamako. With no authorisation to move outside the city, the researcher cannot but be, on the one hand, a fixed point of observation of informants' movements in and out of the city. On the other hand, the progressively acquired capacity to move through Bamako's Kel Tamasheq families – sometimes depending on others, sometimes autonomously – resituates a mobile approach within a context of general immobility. As these two levels of observations collide, this article reflects on an emerging methodological approach to 'discontinuous (im)mobility'. The article suggests that strategic (im)mobility is key to comprehending the extension and organisation of different relationships. By discontinuous (im)mobility this article means a not-necessarily pre-planned organisation of the researcher's mobility while doing fieldwork. Initially this might seem to lead to great confusion in collecting and analysing qualitative ethnographic data. However, in the long run it provides a rich and varied corpus of observations and interactions that are inclusive and intra-scalar. Readiness to be (im)mobile, to navigate volatility, is the norm that is not grasped by equilibrium-driven methodological approaches based on ordered and sequential fieldwork design. This discontinuous (im) mobility allows us to comprehend the entanglement and ongoing reproduction of such variabilities, whose change is hastened by the shifting socio-political context in Mali. To support my argument, the article takes the example of tbushak, a practice of visiting relatives and friends.
The Mismeasurement of Cattle Ownership In Namibia's Northern Communal Areas
Authors: Groves Dylan , Tjiseua Venomukona
Published: October 2020

The standard approach to measuring livestock ownership in pastoralist communities relies on an assumption of uniformity that does not reflect the diverse concepts of ownership held by pastoralists themselves. In Namibia’s Koakaveld Region, Himba and Herero pastoralist communities have a rich vocabulary for categorising the origins, usage rights and cultural valence of their cattle. Drawing on both authors’ experience overseeing a large-scale rangeland management programme evaluation in Namibia’s Northern Communal Areas – and one author’s experience growing up in and keeping cattle in a Himba pastoralist community – we show how the standard approach to measuring cattle ownership undermines accurate estimates of livestock wealth, off-take and inequality, and obfuscates pastoralist’s strategies for turning ecological variability to their advantage. We conclude with lessons about how multi-dimensional data collection methods improve upon the standard approach to livestock ownership measurements.

Der Morgenkreis in Kindertageseinrichtungen – Untersuchung eines alltäglichen pädagogischen Settings
Authors: Burghardt Lars , Kluczniok Katharina
Published: October 2020

Morgenkreise, verstanden als ein morgendlich, regelmäßig stattfindendes Zusammenkommen der Gesamtheit einer Kindertageseinrichtungsgruppe, können als alltägliches pädagogisches Setting beschrieben werden. Trotz der enormen Verbreitung dieser wiederkehrenden Routine findet sich kaum Forschung über Struktur, Inhalte und Ziele des Morgenkreises. Internationale Forschungsergebnisse deuten darauf hin, dass der Morgenkreis ein geeignetes (Interventions-)Setting sein kann, um aus dieser alltäglichen Situation eine Bildungs- bzw. Lernsituation zu schaffen. Die Strukturierung und Inhalte dieses pädagogischen Settings sind Gegenstand der vorliegenden Studie. Insgesamt wurden 28 Morgenkreise beobachtet und die zuständigen pädagogischen Fachkräfte nach ihren Einstellungen und beabsichtigten Zielen bei der Durchführung befragt. Die Analysen deuten darauf hin, dass Morgenkreise eine bestimmte Struktur aufzeigen, insbesondere sprachliche Aktivitäten wie Erzählrunden oder das Abzählen der anwesenden Kinder sind feste Bestandteile des Ablaufs. Insgesamt zeichnen sich die befragten pädagogischen Fachkräfte durch hohe positive Einstellungen gegenüber dem Morgenkreis aus, sie leiten diesen gerne und sehen ihn ebenso als wichtigen Bestandteil des Kita-Alltags an. Die verfolgten Ziele reichen vom kindlichen Sprachanlass bis zur Stärkung des Gruppengefühls. Die Ergebnisse werden diskutiert und praktische Implikationen herausgestellt.

Authors: Song Shouxu , Hu Mengcheng , Xia Yan
Published: October 2020

In order to optimize and analyze the cogging torque of hybrid stator motor, a hybrid stator motor is taken as the research project. The axial distribution of air gap magnetic flux density was analyzed, and the analytical formula of the cogging torque of the hybrid stator motor was derived. Combined with the cogging torque analytical formula, the superposition calculation method of cogging torque of hybrid stator motor was proposed, and the correctness of the superposition calculation method was verified by simulation analysis. The silicon steel segment and the amorphous alloy segment of hybrid stator core were optimized by using the uneven air gap structure, and the optimized results of the silicon steel segment and the amorphous alloy segment were obtained by two-dimensional simulation. Based on the results of two-dimensional simulation analysis, a three-dimensional model was built for simulation analysis. After optimization, the cogging torque of the motor was weakened by 48.1% and the torque ripple was reduced by 1.32%, while the loss and output torque remained basically unchanged.

Huntington Disease-Like 2 (HDL2) is a rare autosomal dominant disorder caused by an abnormal CAG/CTG triplet repeat expansion on chromosome 16q24. The symptoms of progressive decline in motor, cognitive and psychiatric functioning are similar to those of Huntington’s disease (HD). The psychiatric features of the HDL2 have been poorly characterized.

Objective:

To describe the neuropsychiatric features of HDL2 and compare them with those of HD.

Methods:

A blinded cross-sectional design was used to compare the behavioural component of the Unified Huntington’s Disease Rating Scale (UHDRS) in participants with HDL2 ( n = 15) and HD ( n = 13) with African ancestry.

Results:

HDL2 patients presented with psychiatric symptoms involving mood disturbances and behavioural changes that were not significantly different from those in the HD group. Duration of disease and motor performance correlated ( p < 0.001) with the Functional Capacity score and the Independence score of the UHDRS. HD patients reported movement dysfunction as the first symptom more frequently than HDL2 Patients ( p < 0.001).

Conclusion:

The psychiatric phenotype of HDL2 is similar to that of HD and linked to motor decline and disease duration. Psychiatric symptoms seem more severe for HDL2 patients in the early stages of the disease.

Published: October 2020

Like many open-source technologies such as UNIX or TCP/IP, Hadoop was not created with Security in mind. Hadoop however evolved from the other tools over time and got widely adopted across large enterprises. Some of Hadoop’s architectural features present Hadoop its unique security issues. Given this security vulnerability and potential invasion of confidentiality due to malicious attackers or internal customers, organizations face challenges in implementing a strong security framework for Hadoop. Furthermore, given the method in which data is placed in Hadoop Cluster adds to the only growing list of these potential security vulnerabilities. Data privacy is compromised when these critical and data-sensitive blocks are accessed either by unauthorized users or for that matter even misuse by authorized users. In this paper, we intend to address the strategy of data block placement across the allotted DataNodes. Prescriptive analytics algorithms are used to determine the Sensitivity Index of the Data and thereby decide on data placement allocation to provide impenetrable access to an unauthorized user. This data block placement strategy aims to adaptively distribute the data across the cluster using innovative ML techniques to make the data infrastructure extra secured.

The teaching quality is the core of sustainable development in colleges and universities. The constructing scientific and reasonable teaching quality evaluation system is the key of teaching quality evaluation. This paper takes the quality of graduates as the core content, establishes a results-oriented teaching quality evaluation system in colleges and universities, and finds that the academic level of graduates and the level of competition in career selection are two quantitative dimensions reflecting the quality of graduates. Based on this, this paper establishes the evaluation model of the developmental potential index and gives the reference of the norm of teaching effect evaluation for self-evaluation. Finally, this paper discusses the components of graduate quality and the way to construct the evaluation system.

Authors: Lilingling
Published: October 2020

With the continuous development of society, work pressure and study pressure are increasingly becoming the key factors affecting people’s physical and mental health, especially for college students, good knowledge and skills as well as superior psychological quality are the important factors for them to become excellent talents. As an important factor affecting people’s psychological quality, mental health has been paid more and more attention by people. The effect of traditional mental health education in daily education activities is not very obvious, which cannot achieve a profound impact on people’s mental health training and development. In this paper, based on the artificial intelligence online technology, an expert system of mental health education and daily consultation is designed. The system mainly integrates four application modules: psychological knowledge learning, psychological daily evaluation, psychological expert consultation and personal personalized management. The experiment shows that the artificial intelligence online expert consultation system designed in this paper can query daily psychological problems conveniently and quickly. At the same time, the treatment of human psychological problems can be realized through the intelligent online psychological counselling and the relief of psychological symptoms. The artificial intelligence online mental health education system has obvious practical value and social significance.

The popularization of virtual reality technology has become a brand-new carrier of knowledge and information dissemination and a new tool for art creation and design teaching in Colleges and universities. In this paper, first of all, from the three aspects of the definition and characteristics of virtual reality technology, the integration of virtual reality technology into art design teaching, and the significance of using virtual reality technology in art design teaching, the reform of art creation and design teaching in Colleges and Universities under virtual reality technology is discussed. In order to carry out the application research, this paper then chooses to carry on the simulation modeling teaching of the bamboo forest in the intelligent virtual reality environment, making full use of the intelligent modeling tools, rendering tools and mapping tools to complete the teaching application examples of the art modeling design in Colleges and universities. In the specific teaching of art creation and design in Colleges and universities, the creation and design modeling of individual bamboos, the creation and design modeling of bamboos forest, and the creation and design modeling of different lighting effects and scene rendering are carried out respectively. Finally, from the advantages of intelligent virtual reality technology in art creation and design of colleges and universities, the expansion and promotion of teaching resources, and the synergistic effect of teaching results, we analyze the strategies of art creation and design teaching in Colleges and Universities under the background of intelligent virtual reality technology in detail.

Intrusion Detection Systems (IDS) are designed to provide security into computer networks. Different classification models such as Support Vector Machine (SVM) has been successfully applied on the network data. Meanwhile, the extension or improvement of the current models using prototype selection simultaneous with their training phase is crucial due to the serious inefficacies during training (i.e. learning overhead). This paper introduces an improved model for prototype selection. Applying proposed prototype selection along with SVM classification model increases attack discovery rate. In this article, we use fuzzy rough sets theory (FRST) for prototype selection to enhance SVM in intrusion detection. Testing and evaluation of the proposed IDS have been mainly performed on NSL-KDD dataset as a refined version of KDD-CUP99. Experimentations indicate that the proposed IDS outperforms the basic and simple IDSs and modern IDSs in terms of precision, recall, and accuracy rate.
A continuous review inventory model with complex correlations among components
Authors: Lee Chang-Yong
Published: October 2020

Under a flexible mass-production system, a manufacturer may need to provide highly customized products to meet customer satisfaction. It is likely that components in a customized product are correlated in such a way that the demands of some components depend on those of others. In order to cope with dependence in the demands, we proposed a continuous review multi-item inventory (Q, r) model that included a general form of correlation and dependence in demands among components. We represented the proposed model by using a probabilistic graphical model under the assumption that the demands of all components and their correlations were represented by a multivariate Gaussian probability distribution. By taking an advantage of a directed acyclic graph and its topological order, we demonstrated that the correlated demands among components in the proposed model could be solved without any approximation and assumption. As an illustration of the proposed method, we solved an inventory (Q, r) model of eight correlated components and discussed the experimental results in terms of correlation and dependence in demand.

Duchenne muscular dystrophy is an X-linked, recessive muscular dystrophy in which the absence of the dystrophin protein leads to fibrosis, inflammation and oxidative stress, resulting in loss of muscle tissue. Drug repurposing, i.e. using drugs already approved for other disorders, is attractive as it decreases development time. Recent studies suggested that simvastatin, a cholesterol lowering drug used for cardiovascular diseases, has beneficial effects on several parameters in mdx mice. To validate properly the effectiveness of simvastatin, two independent labs tested the effects of 12-week simvastatin treatment in either young (starting at 4 weeks of age) or adult (starting at 12 weeks of age) mdx mice. In neither study were benefits of simvastatin treatment observed on muscle function, histology or expression of genes involved in fibrosis, regeneration, oxidative stress and autophagy. Unexpectedly, although the treatment protocol was similar, simvastatin plasma levels were found to be much lower than observed in a previous study. In conclusion, in two laboratories, simvastatin did not ameliorate disease pathology in mdx mice, which could either be due to the ineffectiveness of simvastatin itself or due to the low simvastatin plasma levels following oral administration via the food.

BACKGROUND: Selective reporting of trial results is common. OBJECTIVE: To study selective reporting in clinical study reports, company trial registers and publications of quality of life in placebo-controlled trials of antidepressants. METHODS: We compared clinical study reports of four antidepressants (fluoxetine, duloxetine, paroxetine and sertraline) obtained from two European drug regulators, data from online company registers, and publications received or retrieved from Eli Lilly and GlaxoSmithKline. Pfizer was also contacted but did not provide any publications. RESULTS: We included 15 trials (19,015 pages) and 4717 patients. Six trials had used SF-36, seven EQ-5D and two both instruments. Nine of the 15 CSRs (60%) displayed selective reporting. In the companies’ online registers, there was selective reporting for all 15 trials (100%). We received 20 publications from Eli Lilly and retrieved six from the GlaxoSmithKline register. There was selective reporting in 24 of the 26 publications (92%). Despite extensive selective reporting, we found only small differences between placebo and active drugs. CONCLUSIONS: Access to the full raw data from clinical trials and to case report forms for all patients are needed to evaluate the effect of antidepressants on quality of life. Regulatory agencies should refuse to approve drugs or new indications based on incomplete reporting.
