The present expression of radiation of an accelerated point charge is only approximately valid. The exact expression of radiation of an accelerated point charge is derived based on special relativity, and using the Larmor formulation for the radiation of an charged particle being accelerated, but instantaneously at rest. The totaled radiation power obtained by the exact expression is the same as Liénard’s generalization of the Larmor formula.

After fault occurs, the fault diagnosis of wind turbine system is required accurately and quickly. This paper presents a fault diagnostic method for open-circuit faults in the converter of permanent magnet synchronous generator drive for the wind turbine. To avoid misjudgement or missed judgement caused by improper thresholds, the proposed method applies Local Mean Decomposition and Multiscale Entropy into the converter of wind power system fault diagnosis for the first time. This paper uses a novel multiclass support vector machine to (...) classify the faults hardly diagnosed by other methods. Simulation results show that the method has the characteristics of high adaptability, high accuracy, and less diagnosis time. (shrink)

Coal mine safety management involves many interested parties and there are complex relationships between them. According to game theory, a multiparty evolutionary game model is established to analyze the selection of strategies. Then, a simplified three-party model is taken as an example to carry out detailed analysis and solution. Based on stability theory of dynamics system and phase diagram analysis, this article studies replicator dynamics of the evolutionary model to make an optimization analysis of the behaviors of those interested parties (...) and the adjustment mechanism of safety management policies and decisions. The results show how the charge of supervision of government department and inspection of coal mine enterprise impact the efficiency of safety management and the effect of constraint measures and incentive and other measures in safety management.

Megaprojects are implemented by different organisations, such as owners, consultants, and contractors. Gradually, these organisations and their connections can form business networks that influence both the market position of individual organisations and project performance. Previous research on large-scale projects mainly focused on static and homogeneous networks that were constructed by one individual project and/or carried out over one-off collaboration. However, this neglected the consideration of project network diversity, as well as repetitive, dynamic, cross-project coopetition relationship and long-term business networks formed (...) by key actors. Here, we chose Chinese skyscrapers over 300 meters that were built from 1996 to 2015 as typical megaproject cases and analysed the formation and evolution of megaproject business networks from the perspective of interorganisational coopetition. We identified the key actors involved and empirically studied their dynamic network positions over time. The main contributions of this study are threefold. First, we found that past collaboration experience has direct and dynamic impacts on the formation of megaproject business networks. Second, we identified key actors in the interorganisational business network and unveiled their dynamic positions with clear patterns. Third, we highlighted the temporal-spatial effect on the formation and development of business networks, alongside developments in the megaproject market. The findings of this study also provide practical applications for owners to choose collaboration partners and to build high-performance teams and for suppliers to enter and sustain the business in the megaprojects networks.

Control of unsafe behaviors has always been a difficult point in Coal Mine Safety Management. To study the regular pattern of behavior propagations in CMSM, a series of evolutionary dynamical system models are established by the delay and impulsive differential equations. The threshold constraints and impulse responses in the models can accurately correspond to the actual inspection and supervision measures in safety management. Through the simulation analysis and comparison of the system stability, it can be concluded that some proper settings (...) of the TCs and impulse responses bring satisfactory evolutionary stability. Based on the main results of this study, we put forward some decision-making suggestions on the control points and control strategies of unsafe behaviors in safety management. (shrink)

Although Chinese Marxism—primarily represented by Maoism—is generally seen by Western intellectuals as monolithic, Liu Kang argues that its practices and projects are as diverse as those in Western Marxism, particularly in the area of aesthetics. In this comparative study of European and Chinese Marxist traditions, Liu reveals the extent to which Chinese Marxists incorporate ideas about aesthetics and culture in their theories and practices. In doing so, he constructs a wholly new understanding of Chinese Marxism. Far from being secondary (...) considerations in Chinese Marxism, aesthetics and culture are in fact principal concerns. In this respect, such Marxists are similar to their Western counterparts, although Europeans have had little understanding of the Chinese experience. Liu traces the genealogy of aesthetic discourse in both modern China and the West since the era of classical German thought, showing where conceptual modifications and divergences have occurred in the two traditions. He examines the work of Mao Zedong, Lu Xun, Li Zehou, Qu Qiubai, and others in China, and from the West he discusses Kant, Schiller, Schopenhauer, and Marxist theorists including Horkheimer, Adorno, Benjamin, and Marcuse. While stressing the diversity of Marxist positions within China as well as in the West, Liu explains how ideas of culture and aesthetics have offered a constructive vision for a postrevolutionary society and have affected a wide field of issues involving the problems of modernity. Forcefully argued and theoretically sophisticated, this book will appeal to students and scholars of contemporary Marxism, cultural studies, aesthetics, and modern Chinese culture, politics, and ideology.

Compiled in the twelfth century A.D. by Chu Hsi, leading exponent of Neo-Confucianism, with the assistance of Lü Tsu-Ch'ien, Chin-ssu Lu serves as a summary of, and introduction to, the vast literature of Neo-Confucian philosophy. Adding a more rational theoretical foundation and new methods of moral cultivation and study to traditional thought and practice, Neo-Confucianism has exercised great influence upon thought and social life in East Asia in the past six hundred years. As the classical statement of this philosophy, this (...) anthology brings together passages from Chou Tun-i, Ch'eng Hao and Ch'eng I, and Chang Tsai on the Way, Learning, and Self-improvement, as well as assessments of the character of Sages and Worthies; also included is a chapter on the doctrines of Buddhism and Taoism, pointing out ways in which they deviated from the Confucian Way. It is a very stimulating work; indeed almost every sentence has spark and substance. Although it has been widely studied by East Asian scholars, so far in the West there has been only the translation into German by Father Olaf Graf, now virtually unobtainable. With his mastery of Chinese philosophical literature, his industriousness in research and his augmentation of the text by generous quotations from the Chinese, Japanese, and Korean commentaries, the translator has achieved extraordinary success in making the English version even more comprehensible than the original Chinese.--T.

Hao Wang was one of the few confidants of the great mathematician and logician Kurt Gödel. _A Logical Journey_ is a continuation of Wang's _Reflections on Gödel_ and also elaborates on discussions contained in _From Mathematics to Philosophy_. A decade in preparation, it contains important and unfamiliar insights into Gödel's views on a wide range of issues, from Platonism and the nature of logic, to minds and machines, the existence of God, and positivism and phenomenology. The impact of Gödel's theorem (...) on twentieth-century thought is on par with that of Einstein's theory of relativity, Heisenberg's uncertainty principle, or Keynesian economics. These previously unpublished intimate and informal conversations, however, bring to light and amplify Gödel's other major contributions to logic and philosophy. They reveal that there is much more in Gödel's philosophy of mathematics than is commonly believed, and more in his philosophy than his philosophy of mathematics. Wang writes that "it is even possible that his quite informal and loosely structured conversations with me, which I am freely using in this book, will turn out to be the fullest existing expression of the diverse components of his inadequately articulated general philosophy." The first two chapters are devoted to Gödel's life and mental development. In the chapters that follow, Wang illustrates the quest for overarching solutions and grand unifications of knowledge and action in Gödel's written speculations on God and an afterlife. He gives the background and a chronological summary of the conversations, considers Gödel's comments on philosophies and philosophers, and his attempt to demonstrate the superiority of the mind's power over brains and machines. Three chapters are tied together by what Wang perceives to be Gödel's governing ideal of philosophy: an exact theory in which mathematics and Newtonian physics serve as a model for philosophy or metaphysics. Finally, in an epilog Wang sketches his own approach to philosophy in contrast to his interpretation of Gödel's outlook. (shrink)

In this first extended treatment of his life and work, Hao Wang, who was in close contact with Godel in his last years, brings out the full subtlety of Godel's ideas and their connection with grand themes in the history of mathematics and ...

First published in 1974. Despite the tendency of contemporary analytic philosophy to put logic and mathematics at a central position, the author argues it failed to appreciate or account for their rich content. Through discussions of such mathematical concepts as number, the continuum, set, proof and mechanical procedure, the author provides an introduction to the philosophy of mathematics and an internal criticism of the then current academic philosophy. The material presented is also an illustration of a new, more general method (...) of approach called substantial factualism which the author asserts allows for the development of a more comprehensive philosophical position by not trivialising or distorting substantial facts of human knowledge.

Calls for justice and reconciliation in response to political catastrophes are widespread in contemporary world politics. What implications do these normative strivings have in relation to colonial injustice? Examining cases of colonial war, genocide, forced sexual labor, forcible incorporation, and dispossession, Lu demonstrates that international practices of justice and reconciliation have historically suffered from, and continue to reflect, colonial, statist and other structural biases. The continued reproduction of structural injustice and alienation in modern domestic, international and transnational orders generates contemporary (...) duties of redress. How should we think about the responsibility of contemporary agents to address colonial structural injustices and what implications follow for the transformation of international and transnational orders? Redressing the structural injustices implicated in or produced by colonial politics requires strategies of decolonization, decentering, and disalienation that go beyond interactional practices of justice and reconciliation, beyond victims and perpetrators, and beyond a statist world order.

We have studied five intersecting integrated geophysical profiles for the 3D crustal structure of the Lu -Zong ore district to obtain a better understanding of the metallogenesis and provide in-depth information for deep mineral targeting. The profiles, totaling more than 300 km, have reflection seismics and magnetotelluric sounding. Regional gravity surveys were also integrated into this study. New discoveries were obtained regarding the upper crustal structure and deformation based on the integrated analysis of these data. The Lu-Zong ore district consists (...) of four major crustal blocks. They are the Shaxi uplift, Qianshan-Kongcheng Depression in the west, Lu-Zong volcanic basin, and the Along-River uplift in the east. The north–south crustal elements show the northward “step-type” uplift, juxtaposed by two steplike faults, the west–northwest/east–southeast-trending Tangjiayuan-Zhuanqiao Fault and the Lujiang-Huangguzha-Tongling Detachment Fault. The Lu-Zong volcanic basin presents a nonsymmetrical shape with four inward-dipping boundary faults. The northern and eastern boundary faults are deep faults, which control the development and evolution of the Lu-Zong volcanic basin. There are three west–northwest/east–southeast-trending faults and six northeast–southwest-trending faults cutting over the ore district. From north to south, they are the LHTD Fault, Tangjiayuan-Zhuanqiao Fault, and Yijing-Taojiaxiang Fault ; from west to east, the six faults are the Tan-Lu, Chuhe, Luohe-Quekou, Zongyang-Huangtun, Taojiawan-Shijiawan, and Changjiang Thrust Fault. The formation and evolution of the ore-district are mainly affected by the Yanshanian intracontinental orogeny, and they experience the Middle to Late Jurassic compression and subsequent Cretaceous extension, possibly due to the paleo-Pacific northwest-trending subduction. Our studies determined that the CTF is a thrust system in nature and the LHTD is a southwest-dipping detachment. Two Jurassic basins were found, surrounding the northeast and southeast of Lu-Zong volcanics, which may be due to the product of postcollision extension of Indosinian orogeny during the middle and early Late Triassic.

This cogent and knowledgeable critique of the tradition of modern analytic philosophy focuses on the work of its central figures -- Russell, Carnap, and Quine -- and finds it wanting. In its place, Hao Wang unfolds his own original view of what philosophy could and should be. The base of any serious philosophy, he contends, should take as its point of departure the actual state of human knowledge. He explains the relation of this new tradition to mathematical logic and reveals (...) the crucial transitions and mistakes in mainstream Anglo-American philosophy that make a new approach so compelling.Equally at home in philosophy and mathematics, Wang is uniquely qualified to take on the task of critically examining modern philosophy. He carefully traces the path of ideas from Russell and Wittgenstein through the Vienna Circle to modern British and American philosophy, and makes use of his familiarity with the profound thought of Kurt Gödel with whom he has had numerous discussions. He also presents the broader significance of Russell's philosophy, provides a comprehensive and unified treatment of Quine's work in logic and in philosophy, and delineates what is common between Carnap and Quine.

Some maladaptive thought processes are characterized by reflexive and habitual patterns of cognitive and emotional reactivity. We review theoretical and empirical work suggesting that mindfulness—a state of nonjudgmental awareness of the present moment—can facilitate the discontinuation of such automatic mental operations. We propose a framework that suggests a series of more specific mechanisms supporting the de-automatizing function of mindfulness. Four related but distinct elements of mindfulness (awareness, attention, focus on the present, and acceptance) can each contribute to de-automatization through subsequent (...) processes, including discontinuing automatic inference, enhancing cognitive control capacity, facilitating metacognitive insight, and preventing suppression or thought distortion. De-automatizing can, in turn, allow enhancement of adaptive self-control ability and increased well-being. (shrink)

Critical attention directed to John Rawls’s ideal theory has in particular leveled three charges against it: first, its infeasibility; second, its inadequacy for providing normative guidance on actual injustices; and third, its insensitivity to the justice concerns of marginalized groups. Recently, advocates for Rawls’s ideal theory have replied that problems arising at the stage of ideal theory can be addressed at the later stage of his nonideal theory. This article disputes that claim by arguing that although Rawls’s nonideal theory provides (...) a good answer to the infeasibility charge, it does not do so for the second and third charges. To argue for this thesis, I illustrate that nonideal theory in Rawls’s Law of Peoples is unable to identify crucial injustices that emerge in the nonideal conditions of real world globalization.

This paper examines how the latest mega plan and the Belt and Road Initiative will impact the geopolitics of energy and infrastructural development. With a massive change in the supply and demand of global energy and its infrastructure, the transition of international energy order is in the making. While the US is going towards a more isolationist path from its traditional superpower role, there are rising economies such as China, India, Japan, and Russia which are undoubtedly playing a vital role (...) in the geopolitical stage and the other development endeavors. Several regions such as Central Asia, the Arctic, Eastern Mediterranean, and the South China Sea are offering substantial natural gas and oil reserves and drawing global attention to develop energy cooperation. This situation is profoundly influencing the transition of energy order. In this transition, BRI is supposed to play an important role. As a mega development strategy with a robust geostrategic dimension, it purposes to advocate interconnectivity collaboration in framework, exchange, and advancement among the partaking nations. This super arrangement offers a lot of ventures, foundation developments, and modern reconciliation in the energy sector. The country is trying to establish a multilateral platform for endorsing and shielding energy cooperation under BRI. This paper, therefore, attempts to observe how this mega plan will contribute to reshaping the existing energy order as well as the geopolitics of energy with motivation on multifaceted energy collaboration.

The geologically distinct DO-27 and DO-18 kimberlites, often called the Tli Kwi Cho kimberlites, have been used as a testbed for airborne geophysical methods applied to kimberlite exploration. This paper focuses on extracting chargeability information from time-domain electromagnetic data. Three different TEM surveys, having similar coincident-loop geometry, have been carried out over TKC. Each records negative transients over the main kimberlite units and this is a signature of induced polarization effects. By applying a TEM-IP inversion workflow to a versatile time (...) domain EM data set we decouple the EM and IP responses in the observations and then recover 3D pseudo-chargeability models at multiple times. A subsequent analysis is used to recover Cole-Cole parameters. Our models demonstrate that both DO-18 and DO-27 pipes are chargeable, but they have different Cole-Cole time constants: 110 and 1160 μs, respectively. At DO-27, we also distinguish between two adjacent kimberlite units based on their respective Cole-Cole time constants. Our chargeability models are combined with the density, magnetic susceptibility and conductivity models to build a 3D petrophysical model of TKC using only information obtained from airborne geophysics. Comparison of this final petrophysical model to a 3D geological model derived from the extensive drilling program demonstrates that we can characterize the three main kimberlite units at TKC: HK, VK, and PK in three dimensions by using airborne geophysics.
