System informatization is a synthetic application which combines control science, computer science and network technology. Informatization technology is more and more applied in industry control system because of its simple structure, easy maintenance and high reliability. This article reviews the development history of informatization, and introduces its current research statuses. Based on the basic theories and composition of informatization systems, this paper deals with the problem of observer and controller design for a class of informatization systems where the network connection only exists between the sensor and controller. Finally, the future developments of informatization system are outlined.

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.

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.

<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>

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.

Strapdown seekers are superior to platform seekers for their simple structure, high reliability and light weight but cannot measure the line-of-sight angle rate information for the guidance of rotation missile directly. This paper aims at the engineering application of full-strapdown seekers on rotation missile problem. Firstly, a line-of-sight angle rate solution model is established. Based on the MATLAB, the extended Kalman filter (EKF) algorithm and unscented Kalman filter (UKF) algorithm are used to estimate the line-of-sight angle rate information of the full-strapdown seekers. The results show that using EKF filter and UKF filter both can obtain effective guidance information and the UKF’s effect is better.

Proportional integral derivative (PID) controllers are commonly used in process industries due to their simple structure and high reliability. Efficient tuning is one of the relevant issues of PID controller type. The tuning process always becomes a challenging matter especially for multivariable system and to obtain the best control tuning for different time scales system. This motivates the use of singularly perturbation method into the multivariable PID (MPID) controller designs. In this work, wastewater treatment plant and Newell and Lee evaporator were considered as system case studies. Four MPID control strategies, Davison, Penttinen-Koivo, Maciejowski, and Combined methods, were applied into the systems. The singularly perturbation method based on Naidu and Jian Niu algorithms was applied into MPID control design. It was found that the singularly perturbed system obtained by Naidu method was able to maintain the system characteristic and hence was applied into the design of MPID controllers. The closed loop performance and process interactions were analyzed. It is observed that less computation time is required for singularly perturbed MPID controller compared to the conventional MPID controller. The closed loop performance shows good transient responses, low steady state error, and less process interaction when using singularly perturbed MPID controller.
