Opis:

Content-based image retrieval methods develop rapidly with a growing scale of image repositories. They are usually based on comparing and indexing some image features. We developed a new algorithm for finding objects in images by traversing their edges. Moreover, we describe the objects by histograms of local features and angles. We use such a description to retrieve similar images fast. We performed extensive experiments on three established image datasets proving the effectiveness of the proposed method.

Shakespearean criticism

Opis:

Chinese Shakespearean criticism from Marxist perspectives is highly original in Chinese Shakespeare studies. Scholars such as Mao Dun, Yang Hui, Zhao Li, Fang Ping, Yang Zhouhan, Bian Zhilin, Meng Xianqiang, Sun Jiaxiu, Zhang Siyang and Wang Yuanhua adopt the basic principles and methods of Marxism to elaborate on Shakespeare’s works and have made great achievements. With ideas changed in different political climates, they have engaged in Shakespeare studies for over eight decades since the 1930s. At the beginning of the revolutionary age, they advocated revolutionary literature, followed Russian Shakespearean criticism from the Marxist perspective, and established the mode of class analysis and highlighted realism. Before and after the Cultural Revolution, they were concerned about class, reality and people. They also showed the “left-wing” inclination, taking literature as a tool to serve politics. Since the 1980s, they have been free from politics and entered the pure academic realm, analysing Shakespearean dramas with Marxist aesthetic theories and transforming from sociological criticism to literary criticism.

The relations between spin-Hamiltonian parameters and local structure around $Cr^{3+}$ in diammonium hexaaqua magnesium sulphate single crystal were established. On the basis of this, the spin-Hamiltonian parameters, optical spectra and the local structure were investigated successfully. The calculated results are in good agreement with experimental data. This shows that the distortion model adopted in this paper is reasonable.

Opis:

As the pace of Chinese economy’s development continues to increase, the “Chinese fever” has already become a common phenomenon within the global language communication system. Teaching Chinese as a foreign language (TCFL), regardless of the method of choice (audiolingual method, direct method, or communicative approach), is impossible without grammar. Regarding TCFL, the goal of teaching grammar is to make foreign students understand the distinguishing features of Chinese grammar and help them master its rules to correctly use the language, develop communicative competence, and efficiently increase proficiency in Chinese. This paper incorporates some living examples and, by discussing the grammatical teaching of Chinese as a foreign language, should answer some questions connected to its principles.
Поскольку темп развития экономики Китая продолжает расти, «бум» на изучение китайского языка уже стал обычным явлением в глобальной системе языковой коммуникации. Преподавание китайского языка как иностранного, независимо от выбранного метода (аудиолингвистиче- ский метод, прямой метод или коммуникативный подход), невозможно без грамматики. Что касается преподавания китайского языка как ино- странного, цель обучения грамматике – научить иностранных студен- тов понимать отличительные особенности китайской грамматики и по- мочь им усвоить ее правила, чтобы они могли правильно использовать язык, развить коммуникативную компетенцию и эффективно повысить уровень владения китайским языком. Эта статья включает несколько живых примеров и, рассказывая о преподавании грамматики китайско- го языка как иностранного, должна ответить на некоторые вопросы, связанные с его принципами.

The permanental polynomial $ \pi (G,x) = \Sigma_{i=0}^n b_i x^{n − i} $ of a graph G is symmetric if $ b_i = b_n−i $ for each $i$. In this paper, we characterize the graphs with symmetric permanental polynomials. Firstly, we introduce the rooted product $ H(K) $ of a graph $ H $ by a graph $ K $, and provide a way to compute the permanental polynomial of the rooted product $ H(K) $. Then we give a sufficient and necessary condition for the symmetric polynomial, and we prove that the permanental polynomial of a graph $ G $ is symmetric if and only if $ G $ is the rooted product of a graph by a path of length one.

Opis:

Thomassen, [Edge-disjoint Hamiltonian paths and cycles in tournaments, J. Combin. Theory Ser. B 28 (1980) 142–163] proved that every strong tournament has a pair of arc-disjoint Hamiltonian paths with distinct initial vertices and distinct terminal vertices if and only if it is not an almost transitive tournament of odd order. As a subclass of local tournaments, Li et al. [Arc-disjoint Hamiltonian cycles in round decomposable local tournaments, Discuss. Math. Graph Theory 38 (2018) 477–490] confirmed the existence of such two paths in 2-strong round decomposable local tournaments. In this paper, we show that every strong, but not 2-strong, round decomposable local tournament contains a pair of arc-disjoint Hamiltonian paths with distinct initial vertices and distinct terminal vertices except for three classes of digraphs. Thus Thomassen's result is partly extended to round decomposable local tournaments. In addition, we also characterize strong round digraphs which contain a pair of arc-disjoint Hamiltonian paths with distinct initial vertices and distinct terminal vertices.

Opis:

Poland is one of the first countries to establish diplomatic relations with People’s Republic of China. Since the establishment of diplomatic ties 70 years ago, both countries have conducted close cooperation in all areas and the bilateral relations have witnessed steady development. In particular, the “One Belt, One Road” initiative, launched in 2013, got the positive responses and support from many countries, including Poland, which became an important partner for China to promote the construction of the initiative. This paper, from a historical perspective, reviews the first interaction between China and Poland in the period of Yuan Dynasty which is arranged in chronological order. The narrations mainly concentrate on accounts of the western expeditions by Genghis Khan and his descendants as well as the Battle of Legnica, during the period of which the Mongolia Empire was successively set up. Each entry will include a concrete description, highlighting where possible issues such as where the Mongolia went, why the expedition and its record are important. The paper also expounds the first record about Poland and the change of the name of Poland in Chinese literature so as to deepen the mutual understanding between two countries.
Польша - одна из первых стран, установивших дипломатические отношения с Новым Китаем. С момента установления дипломатических отношений 70 лет назад обе страны поддерживают тесное сотрудничество во всех областях и двусторонние отношения стабильно развиваются. В частности, инициатива «Один пояс, один путь», запущенная в 2013 году, получила положительные отклики и поддержку многих стран, включая Польшу, которая стала для Китая важным партнером в продвижении инициативы строительства. В этой статье с исторической точки зрения рассматривается первое взаимодействие Китая и Польши в период династии Юань, что представлено в хронологическом порядке. Повествование в основном сосредоточено на рассказах о западных экспедициях Чингисхана и его потомков, а также о битве при Легнице, в период которой последовательно создавалась Монгольская империя. Статья также рассказывает о первом упоминании о Польше и изменении названия Польши в китайской литературе.

Opis:

Learning Chinese is far from an easy task and acquiring Chinese characters is probably the greatest challenge. Many foreign students outside the Chinese Character Culture Circle, beginners in particular, give up learning Chinese characters because of the ideographic system. This system embraces phonology, glyphs and semantic meaning, which are completely different from alphabetic writing. What makes things worse is that TCCF has been ignored for a long time in TCFL. TCFL started to develop in China in the early 1950s, and that involved teaching some simple characters including strokes, the order of strokes and structural analysis. There were no independent character textbooks for foreigners. The content concentrating on teaching characters did not play a leading role in materials for teaching Chinese. Furthermore, most teachers paid little attention to, or neglected character teaching and training, due to the lack of linguistic knowledge.

Opis:

The history of AIIB and SRF is shorter than most of institutes, however so far the two institutes have earned their reputation through business development, and enhanced the confidence of world to B&R initiative. The key hypothesis of this paper is that the two institutes are not some kinds of economic weapons invented to destroy existing world order but new organizations to improve cooperation of countries. The AIIB and SRF are welcomed widely especially by the members in core region of B&R initiative for several reasons. First, they play indispensable role as the public financing institutes, separately being classed as MDB (multilateral development bank) and SWF (sovereign wealth funds) ,both are important for Sustainable development investments .Second , they may help to transfer experiences of China and other fast growing countries to undeveloped countries. The third and may be the most important point is, the two institutes may help more cooperation to be realized following B & R initiative. The missions and functions of the two institutes are fostering sustainable development, promoting regional cooperation, and decreasing the barrier of infrastructure financing. By provide debt financing and capital financing respectively, the two institutes may satisfy different customers with demands of the infrastructure financing in the region. With the transparency process/governance, the two institutes will act not only new pools of development financing in belt and road region, but also a promoter and organizer of development financing industry, which may bring more opportunities to the countries in the region, and improve both intergovernmental and non-GOV cooperation to boost infrastructure financing. The scale of the business of the two institutes has been increased apparently since founded, mainly attributed to regenerative feedback effect caused by multi-win strategy, and the unique position pegged with one belt one road initiative. One interesting thing for IR scholars is , the two new institutes, as long as China the initiator of B & R initiative, have been doubted by some countries while embraced by some others, for being labeled as challengers of the existing world order. This may remind scholars the metaphor of the trap of Thucydides: the trap did exist for those who thought the threat was there and tried to prevent it happened.

Opis:

This paper explores the nature of interlanguage (IL) as a developing system with a focus on the abstract lexical structure underlying IL construction. The developing system of IL is assumed to be ‘composite’ in that in second language acquisition (SLA) several linguistic systems are in contact, each of which may contribute different amounts to the developing system. The lexical structure is assumed to be ‘abstract’ in that the mental lexicon contains abstract elements called ‘lemmas’, which contain information about individual lexemes, and lemmas in the bilingual mental lexicon are language-specific and are in contact in IL production. Based on the research findings, it concludes that language transfer in IL production should be understood as lemma transfer of the learner's first language (L1) lexical structure at three abstract levels: lexical-conceptual structure, predicate-argument structure, and morphological realization patterns, and IL construction is driven by an incompletely acquired abstract lexical structure of a target language (TL) item.

The article points out that American schools have long been serving to Americanize its immigrant population regardless of where they are originally from, ethnically, linguistically, culturally, and religiously, and in spite of the country’s long--standing and ever-growing diversity. Without challenging the structural inequality inherent in “assimilation”, true multiculturalism will not be realized in education.

Opis:

We have two motivations. Firstly, semantic gap is a tough problem puzzling almost all sub-fields of Artificial Intelligence. We think semantic gap is the conflict between the abstractness of high-level symbolic definition and the details, diversities of low-level stimulus. Secondly, in object recognition, a pre-defined prototype of object is crucial and indispensable for bi-directional perception processing. On the one hand this prototype was learned from perceptional experience, and on the other hand it should be able to guide future downward processing. Human can do this very well, so physiological mechanism is simulated here. We utilize a mechanism of classical and non-classical receptive field (nCRF) to design a hierarchical model and form a multi-layer prototype of an object. This also is a realistic definition of concept, and a representation of denoting semantic. We regard this model as the most fundamental infrastructure that can ground semantics. Here a AND-OR tree is constructed to record prototypes of a concept, in which either raw data at low-level or symbol at high-level is feasible, and explicit production rules are also available. For the sake of pixel processing, knowledge should be represented in a data form; for the sake of scene reasoning, knowledge should be represented in a symbolic form. The physiological mechanism happens to be the bridge that can join them together seamlessly. This provides a possibility for finding a solution to semantic gap problem, and prevents discontinuity in low-order structures.

Quite often, people have negative views on government-linked companies (GLCs) due to the unsatisfactory performance of some key players. In order to improve the performance of GLCs in the country, Malaysian government implemented GLC Transformation Program (GLCT) in 2004. As the program is approaching its ending phase, some efforts are needed to assess the performance of GLCs. This study aimed to examine the influence of EO dimensions on the performance of GLCs. The sample of this study consisted of 153 subsidiaries and branches of G20. Based on the multiple regression analysis performed, this study found that all the five dimensions in EO, namely innovativeness (INNO), pro-activeness (PROA), risk-taking (RISK), competitive aggressiveness (COMP) and autonomy (AUTO) recorded significant positive effects on performance of GLCs. Competitive aggressiveness was identified as the most important factor that influences the performance of GLCs. As such, all the hypotheses developed for this study were supported. The results suggested that EO is not only suitable to be applied in privately owned companies, but also in GLCs. Hence, GLCs should not be perceived as public entities and they should be more entrepreneurial in managing their organizations to achieve high performance. Furthermore, this study also verified that EO is a good determinant of GLCs’ performance. At the end of this paper, recommendations for future research have been put forth.

Opis:

Taiwan commands the world’s attention because of the geopolitics that enables the island to play a role bigger than its size. Democracy and secessionist movements that came hand in hand since the 1980s in Taiwan have further complicated matters, leading to a level of chaos and decline of competitiveness in Taiwan’s once-vibrant economy. Cross-Strait relations have greatly improved but the situation remains an “unstable peace,” to use the terminology of the Lund Curve, because of the existence of an independence-leaning coalition and its constituents.Although considerable trade and tourism have linked the two sides and direct negotiations have produced 23 agreements, political and security ties remain sensitive. China’s chief goal remains national reunification, while the majority of Taiwanese voters tend to favor the status quo. This paper discusses a unique two-host phenomenon in Taiwan’s secessionist movement, nonexistent in other similar movements. It traces President Ma Ying-jeou’s approach to cross-Strait relations, explaining reasons that led to Ma’s unprecedented summit with his counterpart Xi Jinping. Without understanding the concept of the two hosts, it would be impossible to make sense of the extraordinary reconciliation, epitomized in the Xi-Ma handshake.
Tajwan przyciąga uwagę całego świata ze względu na znaczenie geopolityczne wyspy w regionie Azji i Pacyfiku. Demokratyzacji Tajwanu towarzyszą ruchy secesyjne, co stwarza dodatkowe komplikacje. Prowadzi to wzrostu zagrożeń w różnych obszarach, politycznym, militarnym, ekonomicznym. Pomimo, że stosunki w Cieśnienie Tajwańskiej można obecnie określić jako względnie spokojne, sytuacja nadal nosi znamiona „niestabilnego pokoju””, używając terminologii zaproponowanej przez Lund Curve. W sytuacji gdy nadrzędnym celem Chin pozostaje zjednoczenie narodowe, większość tajwańskich wyborców faworyzują zachowanie status quo. Tym bardziej na uwagę zasługuje analiza bezprecedensowego spotkania prezydenta Ma Ying-jeou (Tajwan) z Xi Jinping (Chiny), które miało miejsce w listopadzie 2015 roku. Było to pierwsze spotkania tej rangi urzędników od zakończenia wojny domowej czyli od 1949 r.

At the national symposium on the reform of state-owned enterprises, General Secretary Xi Jinping gave important instructions that state-owned enterprises are important forces in strengthening the country’s overall strength and safeguarding the common interests of the people. Therefore, the country must make state-owned enterprises „stronger, better, and bigger”. Huge objections arose in the academic field. This article thoroughly analyzes China’s state-owned economy from the perspective of Marx’s historical materialism, national productivity, and social development, and clarifies the historical status and role of China’s state-owned economy. At the same time, this article comprehensively analyzes the economic significance of making state-owned enterprises „stronger, better, and bigger” from the perspective of total factor productivity, and proposes that since the state-owned economy is backed up by the state, investing in technology research and development has its advantages. However, because the state-owned economy is biased toward administrative instructions, it often lacks efficiency, so if the state-owned economy wants to become „stronger, better, and bigger”, it must undergo reforms in terms of management efficiency.

Opis:

This paper proposes a dynamic economic model with health, human capital and wealth accumulation with elastic labor supply. The economic system consists of one industrial, one health, and one education sector. Our model is a synthesis of four main models in economic theory: Solow’s one-sector neoclassical growth mode, the Uzawa-Lucas two sector model, Arrow’s learning by doing model, and Grossman’s growth model with health. The model also includes Zhang’s idea about creative leisure or learning by consuming. Demand and supply of health service and education are determined by market mechanism. The model describes dynamic interdependence among wealth, health, human capital, economic structure, and time distribution among work, health caring, and education under perfect competition. We simulate the model and examine effects of changes in the propensity to consume health caring, the efficiency of producing health caring, the propensity to receive education, and the propensity to save.

Opis:

The purpose of this paper is to study economic growth with family-based microeconomic foundation. It develops a neoclassical growth model of endogenous wealth accumulation and consumption of two-person families. Growth mechanism and economic structures are based on a generalized Solowian growth model with Zhang’s concept of disposable income and utility. Each spouse maximizes his/her utility function which is dependent on his/her egocentric utility function and the spouse’s egocentric utility function. One’s egocentric utility function is related to one’s private consumption of goods, consumption of family goods, and saving made out of one’s own disposable income. The couple’s decisions are interdependent and are modelled as a Cournot-Nash game. Our model endogenously determines intra-household wealth accumulation and resource allocation on consumption and saving. The paper make an integration of some basic ideas in neoclassical growth theory and family economics. We conduct comparative dynamic analyses to show how the movement of the economy is affected by different exogenous changes in gender relations, preferences, and technologies.

Opis:

In this study, the data from the Programme for International Student Assessment (PISA) are used to investigate whether the PISA science test score is a good indicator of competence in science and technology. The researcher uses a number of scientific and technical journal articles per million people as a measure instrument to represent the competence of science and technology. A regression model analysis suggests that the PISA science scores would significantly predict competence in S & T, even when controlling the number of researchers in R&D per million people and the R&D expenditure (% of GDP). Moreover, it shows that R&D expenditure (% of GDP) is another important determinant of the competence in S & T. Multicollinearity is also found between the R&D expenditure (% of GDP) and the number of researchers in R&D per million people. The policy implication is clear.

Opis:

Let {Fₙ} be the Fibonacci sequence defined by F₀=0, F₁=1, $F_{n+1}=Fₙ+F_{n-1} (n≥1)$. It is well known that $F_{p-(5//p)}≡ 0 (mod p)$ for any odd prime p, where (-) denotes the Legendre symbol. In 1960 D. D. Wall [13] asked whether $p²|F_{p-(5//p)}$ is always impossible; up to now this is still open.
In this paper the sum $∑_{k≡ r (mod 10)}{n\choose k}$ is expressed in terms of Fibonacci numbers. As applications we obtain a new formula for the Fibonacci quotient $F_{p-(5/p)}/p$ and a criterion for the relation $p|F_{(p-1)//4}$ (if p ≡ 1 (mod 4), where p ≠ 5 is an odd prime. We also prove that the affirmative answer to Wall's question implies the first case of FLT (Fermat's last theorem); from this it follows that the first case of FLT holds for those exponents which are (odd) Fibonacci primes or Lucas primes.

Opis:

An edge ranking of a graph is a labeling of edges using positive integers such that all paths connecting two edges with the same label visit an intermediate edge with a higher label. An edge ranking of a graph is optimal if the number of labels used is minimum among all edge rankings. As the problem of finding optimal edge rankings for general graphs is NP-hard [12], it is interesting to concentrate on special classes of graphs and find optimal edge rankings for them efficiently. Apart from trees and complete graphs, little has been known about special classes of graphs for which the problem can be solved in polynomial time. In this paper, we present a polynomial-time algorithm to find an optimal edge ranking for a complete bipartite graph by using the dynamic programming strategy.

This paper generalizes the dynamic growth model with wealth accumulation, technological change and environmental change by Zhang (2012) by making all the parameters as time-dependent parameters. The model treats physical capital accumulation, knowledge creation and utilization, and environmental change as endogenous variables. It synthesizes the basic ideas of the neoclassical growth theory, Arrow’s learning-by-doing model and the traditional dynamic models of environmental change within a comprehensive framework. The behavior of the household is described with an alternative approach to household behavior. We simulated the model to demonstrate existence of equilibrium points, motion of the dynamic system, and oscillations due to different exogenous shocks.

Opis:

This paper extends the growth model for a closed national economy by Zhang (2015) to a small-open economy. We attempt to explain some economic mechanisms of how the richest one per cent of the population own 50% of national wealth. We consider endogenous wealth and human capital accumulation by heterogeneous households with different preferences and learning abilities as the main determinants of growth and inequality. We describe the production technologies and economic structure on the basis of the Uzawa two-sector model. By applying Zhang’s concept of disposable income and approach to household behavior, we describe consumers’ wealth accumulation and consumption behavior. We model human capital accumulation on the basis of Arrow’s learning by doing and Zhang’s creativity with leisure. We simulate the model with three groups of the population, the rich 1 %, the middle 69%, and the poor 20%. We demonstrate the existence of an equilibrium point at which the rich 1% own more than half of the national wealth and the poor 20% less than 10% of the national wealth. We show how the system moves to the equilibrium from an initial state and confirm that the equilibrium point is stable. We also conduct comparative dynamic analysis.

The results show that the contributions to D, $g_∥$ and $g_⊥$ from the spin-orbit interaction are dominant. The contributions from weaker magnetic interactions to D decrease (increase) with increasing charge of impurity ions for $3d^2 (3d^8)$ ions.

Opis:

W niniejszym artykule ukazano postać Tomasza Tian Gengxina, pierwszego „kolorowego” i chińskiego kardynała w dziejach Kościoła katolickiego. Nie chodziło tu jedynie o szkic biograficzny, lecz o ukazanie życia kard. Tian na tle skomplikowanego okresu przełomu XIX i XX wieku w dziejach Chin oraz Tajwanu. To historia Chin tamtego czasu zaważyła na życiu kard. Tian, a nawet przyczyniła się do jego osobistej tragedii – niemożności powrotu do Chin kontynentalnych. Naciski wielu osób, które opowiadały się za powrotem kard. Tian do Pekinu (m.in. abp Antonio Riberi, ks. Domenico Tardini – z ramienia Sekretariatu Stanu Stolicy Apostolskiej) bądź jego pozostaniem na emigracji (abp Yu Bin, Czang Kaj-szek), z pewnością pogłębiały osobisty dramat kardynała. Sytuacja, w jakiej znalazł się kard. Tian, była złożona, a nawet tragiczna. Każdy jego decyzja – czy to pozostanie na miejscu, czy powrót do Pekinu – wydawała się fatalna. Hierarcha miał tego świadomość, którą wyraził w liście z 11 lipca 1954 roku do Chu Cheng-ying. Mimo to nie należy zbyt pochopnie oceniać jego postępowania.
This article presents the figure of Thomas Tian Gengxin, the first “colored” and Chinese cardinal in the history of the Catholic Church. It is not just a biographical sketch, but it shows the life of Cardinal Tian against the background of complicated period of the turn of the 19th and 20th centuries in the history of China and Taiwan. It is the history of China of that time that influenced the life of Cardinal Tian and even contributed to his personal tragedy – the impossibility of returning to mainland China. The pressure of many people who were in favor of the return of Cardinal Tian to Beijing (including Abp. Antonio Riberi, Fr. Domenico Tardini – on behalf of the Secretariat of the State of the Holy See) or his remaining in exile (Abp. Yu Bin, Chiang Kai-shek), certainly deepened the personal drama of the Cardinal. The situation, in which Cardinal Tian found himself was complex and even tragic. Every decision he made – whether he would remain on the spot or return to Beijing – seemed fatal. The hierarch was aware of that and he expressed it in the letter of July 11, 1954 to Chu Cheng-ying. Still, we should not judge his behavior too hastily.

In nuclear fuel reprocessing plants, ion exchange is used for the purification of actinide elements for further use, for the solidification of low- and medium-active waste solutions, and for the partitioning of high-level wastes. This paper reviews selected technological uses of ion exchange in these operations for recovery, separation and purification of selected actinides (Pu, U, Np, etc.). Recent research and development on ion exchange technologies for actinides are also summarized.

In China dry ports enter into a rapid development period now, however for many Chinese dry ports, the operation faces difficulties duo to inefficient logistics networks and cooperation relationship between dry ports and seaports. Focusing on the concession cooperation mechanism of seaports and dry ports, and the environmental constraints (carbon emissions and congestion cost), a bi-objective location-allocation MILP model for the sustainable hinterland-dry ports-seaports logistics network optimization is formulated, aiming at the system logistics costs and carbon emissions to be minimized. Moreover, for the cooperation mechanism of seaports to dry ports, a parameter called cooperation cost concession coefficient is proposed for the optimization model, and a new evaluation method based on the ordered weighted averaging (OWA) operator is used to evaluate it. Then a location-allocation decision-making framework for the hinterland-dry port-seaport logistics network is proposed. The innovative aspect of the model is that it can proposes a effective and environment friendly dry ports location strategic and also give insights into the connective cooperation relationships, and cargo flows of the network. A case study involving configuration of dry ports in Henan Province is conducted, and the model is successfully applied.

In this paper we present our theoretical approach for the description of the light guidance in photonic liquid crystal fibers. In particular, we focus on the numerical methods allowing for a full implementation of the liquid crystals properties (i.e., including their optical anisotropy and molecular orientation), with a final target in characterizing photonic liquid crystal fibers with accessible computational effort. For this purpose suitable analytical formulae required for a full-vectorial description of the optical modes in photonic liquid crystal fibers have been derived. In addition, computational schemes allowing for numerical implementation of theoretical formulations (with the use of the finite-difference scheme) have been developed, validated and optimized. Their numerical convergence has been checked for different structures, as well as for different input parameters (e.g., grid-size). Obtained results have been compared to those analytically calculated, known from literature and/or got with use of commercial software. Moreover, the implemented schemes have been examined in accordance with experimental tests performed on the photonic liquid crystal fiber of interest.

In this paper, we investigate the impact of environmental regulations on employment in China. We apply a quasi-natural experiment on the revision of Water Pollution Prevention and Control Law in 2008 (WPPCL2008), and we analyze manufacturing sectors’ reaction to WPPCL2008 by using a differences-in-differences approach based on China’s thirty five sectors at the 2-digit level from 2003 to 2014. Our results show that although environmental regulations can reduce waste-water emissions, at the same time cause a decrease in employment. The results suggest that stringent environmental regulation is not cost free. Furthermore, this finding contradicts the popular view that the effect of Chinese legislation enforcement is insignificant.

Opis:

This paper investigates the global exponential synchronization and quasi-synchronization of inertial memristive neural networks with time-varying delays. By using a variable transmission, the original second-order system can be transformed into first-order differential system. Then, two types of drive-response systems of inertial memristive neural networks are studied, one is the system with parameter mismatch, the other is the system with matched parameters. By constructing Lyapunov functional and designing feedback controllers, several sufficient conditions are derived respectively for the synchronization of these two types of drive-response systems. Finally, corresponding simulation results are given to show the effectiveness of the proposed method derived in this paper.

Opis:

The mismatch effect of photovoltaic (PV) arrays due to different illumination intensity has a significant impact on the output characteristics and output power of PV arrays, which is crucial to understand the output characteristics of PV arrays and optimize the array configuration in order to improve the value of the maximum power point. This paper illustrates the short-circuit current mismatch of series circuits, and the open-circuit voltage mismatch of parallel circuits and proposes corresponding solutions for each mismatch phenomenon. The output characteristics of multi-stage series PV arrays and multi-stage parallel PV arrays under complex illumination are analyzed by using the peak point approximation calculation method, and the distribution law of peak voltage points as well as the I-V (Current-Voltage) characteristic equation of each operating section are proposed. On this basis, the output characteristics of 3 x 3 centralized PV arrays are analyzed and verified by simulation. By comparing series and parallel PV arrays with the same condition, as well as several groups of centralized PV arrays with the same topology and different types of illumination distribution, this paper proposes a configuration optimization method for PV arrays. Matlab/Simulink simulation results confirm that the output power of parallel arrays is greater than that of series arrays under the same configuration and illuminationt distribution type, and the peak point is less than that of series arrays under the same configuration and lighting conditions; while in centralized PV arrays, the fewer series modules are shaded, the greater the output power and the less the peak point.

Gutin and Rafiey [Multipartite tournaments with small number of cycles, Australas J. Combin. 34 (2006) 17–21] raised the following two problems: (1) Let m ∈ {3, 4, . . ., n}. Find a characterization of strong n-partite tournaments having exactly n − m + 1 cycles of length m; (2) Let 3 ≤ m ≤ n and n ≥ 4. Are there strong n-partite tournaments, which are not themselves tournaments, with exactly n − m + 1 cycles of length m for two values of m? In this paper, we discuss the strong n-partite tournaments D containing exactly n − m + 1 cycles of length m for 4 ≤ m ≤ n − 1. We describe the substructure of such D satisfying a given condition and we also show that, under this condition, the second problem has a negative answer.

Opis:

Liquid storage tank is widely used in the petrochemical industry, earthquake will lead to structural damage and secondary disasters, and damping control opens up a new way for seismic design of liquid storage tank. Considering soil-structure-fluid interaction, liquid sloshing dynamic behavior and material nonlinearity, a three-dimensional calculation model of shock absorption liquid storage tank is established by combining sliding isolation and displacement-limiting devices. The dynamic responses of the liquid storage tanks under the action of Kobe and El-Centro waves are investigated, and the influence of soil-structure interaction (SSI) on the dynamic response is discussed. The results show that the damping ratio is basically between 30% and 90%. After the SSI is considered, the damping ratio of liquid sloshing wave height is increased, while the damping ratio of the dynamic response of the liquid storage tank is decreased, and the change of elastic modulus has little effect on the damping effect. The sliding isolation with displacement-limiting devices has significant damping control effects on the liquid sloshing wave height and the dynamic responses of the liquid storage tank.

Opis:

With respect to multiple attribute decision making problems with interval-valued intuitionistic fuzzy information, some operational laws of interval-valued intuitionistic fuzzy numbers, score function and accuracy function of interval-valued intuitionistic fuzzy numbers are introduced. A combined optimization model based on the deviation method, by which the attribute weights can be determined, is established. For special situations, in which information about attribute weights is completely unknown, we establish another combined optimization model. By solving this model, we get a simple and exact formula, which can be used to determine the attribute weights. We utilize the interval-valued intuitionistic fuzzy weighted averaging (IIFWA) operator to aggregate the intuitionistic fuzzy information corresponding to each alternative, and then rank the alternatives and select the most desirable one(s) according to the score and accuracy functions. Finally, an illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness.

Opis:

The sodium expansion and creep strain of semi-graphitic cathodes are investigated using a modified Rapoport apparatus. To further understanding of the sodium and bath penetration damage processes, the impact of external stress fluence on the carbon cathode microstructure has been defined with XRD analysis, Raman spectroscopy and scanning electron microscope (SEM). Graphite atoms fracture into smaller fragments that are less directional than the pristine platelets, which allows for a possible filling of the cracks that thus develop by the sodium and bath during aluminum electrolysis. The average microcrystalline size (calculated by Raman spectroscopy) is reduced by the deformation. The decreased intensity and widened 'G' and 'D' peaks in the analysis indicate the poor order of the sheets along the stacking direction while the consistent layered graphite structure is sustained.

Opis:

W powyższym artykule autor omawia ideę prawdy w Chinach klasycznych w perspektywie komparatystycznej. W podejściu do idei prawdy kultury zachodnia i chińska różnią się: dla pierwszej kategoria prawdy jest samo przez się zrozumiała, w drugiej zdaje się ona prawie nie występować. Autor stara się najpierw (pierwsza część artykułu) wypracować metodyczno-metodologiczny horyzont spojrzenia na ideę prawdy w Chinach klasycznych, a potem (druga część) na przykładzie Dialogów konfucjańskich przedstawić konfucjański ideał junzi – ludzi szlachetnych – jako nosicieli dao-prawdy. Pierwsza, metodyczno-metodologiczna część artykułu zawiera zarówno problematykę filozoficzną (np. różnicę pomiędzy pojęciem a ideą / teorią a poglądem, historyczność rozumienia jako zasadę hermeneutyczną, pojęcie egzystencji autentycznej jako pierwszorzędną zasadę heurystyczną, potrójny wymiar pojęcia prawdy w zachodniej tradycji filozoficznej jako drugorzędną zasadę heurystyczną, koncepcję prawdy w hermeneutyce jako najbardziej uniwersalną zasadę heurystyczną), jak również sinologiczną problematykę (natura klasycznego języka chińskiego według tradycji chińskiej i sinologów, problem kandydatów leksykalnych problematyki prawdy w klasycznych Chinach, wybór tekstów do analizy i interpretacji idei prawdy w Chinach klasycznych oraz pojęcie Chin klasycznych). Wszystkie te metodycznometodologiczne kroki służą do stworzenia pomostu pomiędzy dwiema odmiennymi ideami prawdy, które powstały na zachodzie i w Chinach.
In the present article, the author describes the idea of truth in the classical China in the comparative perspective. The Western and Chinese cultures differ in their attitudes towards truth: while the former’s understanding of the category of truth is self-evident – in the latter, truth almost seems not to occur whatsoever. The author attempts first to (in the article’s part one) work out the methodical and methodological horizon to look at the idea of truth in classical China, then (part two), on the example of the Analects of Confucius – to introduce the Confucian ideal of junzi, the noble people as the dao-truth bearers. The first, methodical and methodological, part of the article contains both philosophical problems (eg. the difference between a notion and an idea / theory and attitude, the historicity of understanding as the hermeneutic rule, the notion of authentic existence as the primary hermeneutic rule, the triple dimension of the notion of truth in the Western philosophical tradition as the secondary hermeneutic rule, the concept of truth in hermeneutics as the most universal heuristic rule) – as well as the problems of sinology: the nature of the classical Chinese according to the Chinese tradition and sinologists, the problem of the lexical candidates of the questions concerning truth in classical China, selected texts to analyse and convey the idea of truth in classical China and the notion of classical China. All these methodical and methodological steps serve to create a bridge between two different ideas of truth that came into being – one in the West and one in China.

Opis:

The predominant context for strategy research over the last three decades has focused on language learning situated in a conventional classroom environment. Computer technology has brought about many changes in language learning and has become ecological and normalized rather than a supporting tool in the language classroom. Consequently, the landscape of language learning has been rapidly and largely changed with the normalization of technologies in people’s daily communication. The pervasive use of mobile technologies and easy access to online resources require that digital language learners understand and employ appropriate learning strategies for learning effectiveness and that their teachers are able and willing to teach these strategies as needed. This article provides an overview of the state-of-the-art research into technology-enhanced language learning strategies. The strategies under review include those for language learning skill areas, language subsystems, and self-regulated learning. At the end, we discuss the pressing issues that Digital Age language learning has posed to learners, teachers, and researchers and propose considerations for strategy research in digital realms.

Firstly, we introduce the concept and basic operations of the dual hesitant Pythagorean fuzzy sets, which is a new extension of Pythagorean fuzzy sets. Then, motivated by the idea of Bonferroni mean operators, we have developed some Bonferroni mean aggregation operators for aggregating dual hesitant Pythagorean fuzzy information. The prominent characteristic of these proposed operators are studied. Then, we have utilized these operators to develop some approaches to solve the dual hesitant Pythagorean fuzzy multiple attribute decision making problems. Finally, a practical example for supplier selection in supply chain management is given to verify the developed approach and to demonstrate its practicality and effectiveness.

Surface coating technology, as the main technology to improve the fatigue life of mechanical systems, has been well applied in mechanical equipment. The present study aimed to explore low-cost surface coating preparation technology using inexpensive rice husk as the research object, and the pyrolysis process behavior of rice husk was analyzed. The Ni60/SiO2 coating was prepared on the surface of the 45# steel substrate using the pyrolysis product SiO2 fiber as the reinforcing phase and supersonic plasma-spraying equipment. The results showed no defects such as cracks, pores, and inclusions in the prepared coating. The nanohardness of the Ni60/SiO2 coating reached 6506 μN, and the average friction coefficient reached 0.42. In the friction-and-wear experiment, the Ni60/SiO2 coating was manifested as an abrasive wear mechanism.

Opis:

Guo [Outpaths in semicomplete multipartite digraphs, Discrete Appl. Math. 95 (1999) 273–277] proposed the concept of the outpath in digraphs. An outpath of a vertex x (an arc xy, respectively) in a digraph is a directed path starting at x (an arc xy, respectively) such that x does not dominate the end vertex of this directed path. A k-outpath is an outpath of length k. The outpath is a generalization of the directed cycle. A c-partite tournament is an orientation of a complete c-partite graph. In this paper, we investigate outpaths of arcs in regular 3-partite tournaments. We prove that every arc of an r-regular 3-partite tournament has 2- (when r ≥ 1), 3- (when r ≥ 2), and 5-, 6-outpaths (when r ≥ 3). We also give the structure of an r-regular 3-partite tournament D with r ≥ 2 that contains arcs which have no 4-outpaths. Based on these results, we conjecture that for all k ∈ {1, 2, . . ., r − 1}, every arc of r-regular 3-partite tournaments with r ≥ 2 has (3k − 1)- and 3k-outpaths, and it has a (3k + 1)-outpath except an r-regular 3-partite tournament.

Opis:

When the distribution of water quality samples is roughly balanced, the Bayesian criterion model of water-inrush source generally can obtain relatively accurate results of water-inrush source identification. However, it is often difficult to achieve desired classification results when training samples are imbalanced. Sample imbalance is common in the source identification of mine water-inrush. Therefore, we propose a three-dimensional (3D) spatial resampling method based on rare water quality samples, which achieves the balance of water quality samples. Based on the virtual water sample points distributed by the 3D grid, the method uses the 3D Inverse Distance Weighting (IDW) method to interpolate the groundwater ion concentration of the virtual water samples to achieve oversampling of rare water samples. Case study in Gubei Coal Mine shows that the method improves overall discriminant accuracy of the Bayesian criterion model by 5.26%, from 85.26% to 90.69%. In particular, the discriminative precision of the rare class is improved from 0% to 83.33%, which indicates that the method can improve the discriminant accuracy of the rare class to large extent. In addition, this method increases the Kappa coefficient of the model by 19.92%, from 52.26% to 72.19%, increasing the degree of consistency from “general” to “significant”. Our research is of significance to enriching and improving the theory of prevention and treatment of mine water damage.
W przypadku zrównoważonych danych o jakościowym rozkładzie próbek, zastosowanie kryterium Bayesowskiego do modelowania źródeł wycieków daje stosunkowo dokładne wyniki w analizie dyskryminacyjnej źródeł wycieków wody kopalnianej. Jednakże w przypadku niezrównoważonych danych, pożądane efekty kategoryzacji są niezmiernie trudne do uzyskania. Dane o składzie próbek są w znacznej mierze niezrównoważone, i jest to powszechny problem napotykany przy identyfikacji źródeł wycieków. W obecnej pracy zaproponowano więc trójwymiarową (3D) metodę powtórnego próbkowania z wykorzy-staniem próbek wód z kategorii zdarzeń rzadkich, tak by uzyskać zrównoważony zbiór danych. W oparciu o wirtualne punkty na trójwymiarowej siatce, wykorzystano trójwymiarową metodęśredniej ważonej odległością (Inverse Distance Weighing – IDW) do interpolacji stężenia jonów w wodach gruntowych w wirtualnych próbkach wody, w celu nadpróbkowania dla kategorii zdarzeń rzadkich. Studium przypadku kopalni węgla Gubei pokazuje, że metoda poprawia dokładność dopasowania modelu w oparciu o kryterium Bayesowskie o 5.25% (z 85.26% na 90.96 %). W szczególności, dokładność rozróżniania i dyskryminacji próbek należących do kategorii zdarzeń rzadkich wzrasta od 0% do 83.33%, co oznacza bardzo znaczna poprawę. Ponadto, wartość współczynnika Kappa wzrasta o 19.92%, od 52.26 % do 72.19%, tym samym podnosząc poziom zgodności metody z poziomu ogólnego na „znaczący”. Prowadzone przez nas badania mają poważne znaczenie z punktu widzenia udoskonalenia teorii leżących u podstaw metod i technik zapobiegania i kontroli wycieków wód kopalnianych.

Opis:

This paper examines the relationship between stock return and human behavior in ten well-established stock exchanges, from a monthly data sample from January 1991 to December 2015. The results show that there is no sufficient evidence to generalize the impact of human behaviour on common stock return, through mood state altered by weather variables. When the substance of the underlying process (i.e. the weather alters the mood state) is established by logit regression, the results reveal that there is a bias in the variable selection as regressors, which is subject to the metrological situation of each country (or region). As such, collectivism does not appear to be an explanatory variable of the magnitude of price changes, as a variable uncontrolled for in the regression. Although the null hypothesis is accepted for four countries in the sample, the findings do not warrant researchers to generalize the effect of human behavior on stock price changes through weather variables, for a large population.
W tym artykule zbadano związek między zwrotem z akcji a ludzkim zachowaniem na przykładzie dziesięciu uznanych giełd, opierając się na miesięcznej próbce danych z okresu od stycznia 1991 r. do grudnia 2015 r. Wyniki pokazują, że nie ma wystarczających dowodów, aby uogólnić wpływ ludzkich zachowań wywołanych zmiennymi warunkami pogodowymi na zwrot z akcji zwykłych. Gdy zasada leżąca u podstaw procesu (tzn. pogoda zmienia stan nastroju) jest ustalana przez regresję logitów, wyniki ujawniają, że w wyborze zmiennych jako regresorów występuje nastawienie zależne od sytuacji metrologicznej każdego z krajów (lub regionów). Kolektywizm jako taki nie wydaje się zmienną wyjaśniającą wielkość zmian cen jako zmienną niekontrolowaną w regresji. Chociaż hipoteza zerowa w badanej próbie została przyjęta dla czterech krajów, odkrycia te nie upoważniają badaczy do uogólnienia wpływu ludzkich zachowań na zmiany cen akcji przez zmienne pogodowe, dla dużej populacji.

Opis:

This paper examines the relationship between industry competitiveness and common stock returns of twenty listed firms of the Colombo Stock Exchange. The Herfindahl (1950) H index is extended to include the variance of cross sectional earnings dispersion that accounts for the relative competition of an industry. The regression results show that the industry competitiveness is unrelated to common stock returns when the extended H index is included in the regression specification as a common factor. Although the overall market factor (i.e. market return) remains statistically significant, coefficients of extended H index together with two other controlled factors become statistically insignificant in the regression. These findings suggest that the risk pertaining to industry competition is not priced as it could be diversified away by the appropriately managed value chain of the individual firms and, as such, no compensation for the risk of industry competition is demanded.

Opis:

To figure out the reason causing ladle nozzle clogging during CC (continuous casting) of a non-oriented electrical steel with high silicon (or HNO for short) and get a method to address it, this paper studied the theoretical calculation of flow rates during CC, the inclusions around the slide gate where ladle nozzle clogging happened, and Ca-treatment at the end of RH for decreasing ladle clogging of the electrical steel both theoretically and practically. The results showed that: The bigger diameter of a nozzle or less nozzle clogging can guarantee an enough flow rate for reaching the target casting speed. Ladle nozzle clogging can be predicted by comparing the percentage of slide gate opening. Al₂ O₃ and its composite inclusions were the main reason that caused the ladle nozzle clogging of the electrical steel. Higher [Al] or TO will increase the amount of Pure Ca wires for Ca-treatment. The results of the verification tests fit the thermodynamic calculation, and Ca-treatment using pure Ca wires could prevent ladle nozzles from clogging without affecting the magnetic properties of the electrical steel.
