Proper Analysis

ABSTRACTInhomogeneous materials (the ones exhibiting spatial variations in their, all or specific, material properties) present a great deal of interest for scientists and engineers in both academia and industry. For over a hundred years, the mechanical behavior of inhomogeneous materials excites numerous attempts in mathematical modeling and development of methods for proper analysis and verification. With this concern, the reach experience was gained by scientists of different scientific schools in many countries. Despite numerous significant achievements, some results, unfortunately, remain unnoticed by the wide scientific community. On the other hand, one can observe a growing number of publications which repeatedly publish the solutions reported years ago or deal with the similar problems with slight modifications. The main objective of this paper is to: i) present a brief survey of the development history of the elastic analysis of inhomogeneous solids and ii) characterize some dominant analytical and semi-analytical methods. It was not our intent here to provide a comprehensive list of references on the topic, which is nearly impossible to make in view of rapidly growing number of publications and other restrictions, but to emphasize some important, in our opinion, stages of the development, methods and results.

The article is devoted to the satirical agitation ABCs that appeared during the Civil War, which have never previously been identified by researchers as a separate type of agitation art. The ABCs, which used to have the narrow purpose of teaching children to read and write before, became a form of agitation art in the hands of artists and writers. This was facilitated by the fact that ABCs, in contrast to primers, are less loaded with educational material and, accordingly, they have more space for illustrations. The article presents the development history of the agitation ABCs, focusing in detail on four of them: V.V. Mayakovsky’s “Soviet ABC”, D.S. Moor’s “Red Army Soldier’s ABC”, A.I. Strakhov’s “ABC of the Revolution”, and M.M. Cheremnykh’s “Anti-Religious ABC”. There is also briefly considered “Our ABC”: the “TASS Posters” created by various artists during the Second World War. The article highlights the special significance of V.V. Mayakovsky’s first agitation ABC, which later became a reference point for many artists. The authors of the first satirical ABCs of the Civil War period consciously used the traditional form of popular prints, as well as ditties and sayings, in order to create images close to the people. The article focuses on the iconographic connections between the ABCs and posters in the works of D.S. Moor and M.M. Cheremnykh, who transferred their solutions from the posters to the ABCs.

Large-scale tidal power development in the Bay of Fundy has been given serious consideration for over 60 years. There has been a long history of productive interaction between environmental scientists and engineers durinn the many feasibility studies undertaken. Up until recently, tidal power proposals were dropped on economic grounds. However, large-scale development in the upper reaches of the Bay of Fundy now appears to be economically viable and a pre-commitment design program is highly likely in the near future. A large number of basic scientific research studies have been and are being conducted by government and university scientists. Likely environmental impacts have been examined by scientists and engineers together in a preliminary fashion on several occasions. A full environmental assessment will be conducted before a final decision is made and the results will definately influence the outcome.

Choosing solutions under risk and uncertainty requires the consideration of several factors. One of the main factors in choosing a solution is modeling the decision maker’s attitude to risk. The expected utility theory was the first approach that allowed to correctly model various nuances of the attitude to risk. Further research in this area has led to the emergence of even more effective approaches to solving this problem. Currently, the most developed theory of choice with respect to decisions under risk conditions is the cumulative prospect theory. This paper presents the development history of various extensions of the original expected utility theory, and the analysis of the main properties of the cumulative prospect theory. The main result of this work is a fuzzy version of the prospect theory, which allows handling fuzzy values of the decisions (prospects). The paper presents the theoretical foundations of the proposed version, an illustrative practical example, and conclusions based on the results obtained.

AbstractThis review reports the Brazilian history in astrobiology, as well as the first delineation of a vision of the future development of the field in the country, exploring its abundant biodiversity, highly capable human resources and state-of-the-art facilities, reflecting the last few years of stable governmental investments in science, technology and education, all conditions providing good perspectives on continued and steadily growing funding for astrobiology-related research. Brazil is growing steadily and fast in terms of its worldwide economic power, an effect being reflected in different areas of the Brazilian society, including industry, technology, education, social care and scientific production. In the field of astrobiology, the country has had some important landmarks, more intensely after the First Brazilian Workshop on Astrobiology in 2006. The history of astrobiology in Brazil, however, is not so recent and had its first occurrence in 1958. Since then, researchers carried out many individual initiatives across the country in astrobiology-related fields, resulting in an ever growing and expressive scientific production. The number of publications, including articles and theses, has particularly increased in the last decade, but still counting with the effort of researchers working individually. That scenario started to change in 2009, when a formal group of Brazilian researchers working with astrobiology was organized, aiming at congregating the scientific community interested in the subject and to promote the necessary interactions to achieve a multidisciplinary work, receiving facilities and funding from the University de Sao Paulo and other funding agencies.

<p>六群比丘（以下簡稱六群）是佛教史上頗惹爭議的人物，他們既通世情佛理，卻又屢屢違犯律制，故被貶稱為「惡比丘」。可是，近世學人轉以六群的行徑為方便施設，言其旨在令律制更趨完備，六群遂搖身一變成為正面人物。而在眾律藏中，惟「根有部律」清楚舉出六群的身分，同時包含更多的相關記載。</p> <p>本文以漢譯「根有部律」作為基本資料，分三組八類，挑選一些事例作討論。指出六群雖具備相當的律學知識，但他們或固執條文，或挑剔刁難，往往令人討厭難堪。此諸多看似乖張的行止，暴露了僧團運作的毛病和戒律的漏洞，亦令律制得以不斷完善，從中顯示出初期佛教中道和寬容的精神，為佛教律制發展史上值得留意的一章。</p> <p>&nbsp;</p><p>The group-of-six-monks (abbreviated as &quot;&quot;the group-of-six&quot;&quot; thereinafter) is quite controversial personage in the history of Buddhism, whose are always denounced as &quot;&quot;bad monks&quot;&quot;, as they often go against the precepts. However, some Buddhist scholars nowadays re-interpret their misbehaviors as expedient, which make rooms for the Buddha to prescribe or fine-tune the rules and regulations. Among various Vinayas, only the Mūlasarvāstivāda-vinaya clearly provides the identity of the group-of-six and has abundant relevant information. </p> <p> Based on the Chinese Mūlasarvāstivāda-vinaya, this article divides three groups and eight items, selects some examples for discussion, in order to show that the group-of-six have considerable knowledge of monastic discipline, but they stick to the literal meaning of the precepts and challenge other colleagues. As a result, some flaws of the Sangha order and loopholes of the precepts are revealed and given a chance for continuously improvement. Hence, it has showed the middle path and compassion of primitive Buddhism. As such, this is a noteworthy chapter in the development history of Buddhist monastic discipline.</p> <p>&nbsp;</p>

For the pre-revolutionary Don historiography, complaints about the lack of a full-fledged generalizing work of the history of the Cossacks were extremely characteristic. As shown in the article, a similar situation is observed in our time: the article has again become the main genre of Cossack historiography, and the understanding of a huge number of publications on the history of various Cossack troops is extremely difficult. The author proves that in these conditions, works that claim to generalize become especially important, but it is extremely difficult to summarize all the facts, developments and research concepts on any broad topic of Cossack history. In his opinion, the search for other methods of scientific generalization and perception by historians of the developments of their colleagues looks promising. One of these ways he sees the organization of round tables on specifically Cossack topics, especially dedicated to new discoveries.

The Impact

With the continuous development of intelligent technologies, knowledge graph, the backbone of artificial intelligence, has attracted much attention from both academic and industrial communities due to its powerful capability of knowledge representation and reasoning. In recent years, knowledge graph has been widely applied in different kinds of applications, such as semantic search, question answering, knowledge management and so on. Techniques for building Chinese knowledge graphs are also developing rapidly and different Chinese knowledge graphs have been constructed to support various applications. Under the background of the “One Belt One Road (OBOR)” initiative, cooperating with the countries along OBOR on studying knowledge graph techniques and applications will greatly promote the development of artificial intelligence. At the same time, the accumulated experience of China in developing knowledge graphs is also a good reference to develop non-English knowledge graphs. In this paper, we aim to introduce the techniques of constructing Chinese knowledge graphs and their applications, as well as analyse the impact of knowledge graph on OBOR. We first describe the background of OBOR, and then introduce the concept and development history of knowledge graph and typical Chinese knowledge graphs. Afterwards, we present the details of techniques for constructing Chinese knowledge graphs, and demonstrate several applications of Chinese knowledge graphs. Finally, we list some examples to explain the potential impacts of knowledge graph on OBOR.
