IGBT Open-Circuit Fault Diagnosis for MMC Submodules Based on Weighted-Amplitude Permutation Entropy and DS Evidence Fusion Theory

Modular multilevel converters (MMCs) have a complex structure and a large number of submodules (SMs). If there is a fault in one of the SMs, it will affect the reliable operation of the system. Therefore, rapid fault diagnosis and accurate fault positioning are crucial to ensuring the continuous operation of the system. However, the IGBT open-circuit faults in different submodules of MMCs have similar fault features, and the traditional fault feature extraction method cannot effectively extract the key features of the fault so as to accurately locate the faulty submodules. In response to this problem, this paper proposes a fault diagnosis method based on weighted-amplitude permutation entropy (WAPE) and DS evidence fusion theory. The simulation results show that WAPE has better feature extraction ability than basic permutation entropy, and the fused multiscale feature decision output has better diagnostic accuracy than the single-scale feature. Compared with traditional fault diagnosis methods, this method achieves the diagnosis of multiple fault types by collecting a single signal, which greatly reduces the number of samples and leads to higher diagnostic accuracy and faster diagnostic speed.

Imagistic Ritual, Fusion, and Self-Sacrifice

Efforts to investigate the imagistic mode of religiosity initially focused on the effects of emotionally intense rituals on meaning making. But the discovery of a new psychological construct—identity fusion—made it possible to extend the study of imagistic processes to include increasingly precise measures of the pathways to group bonding. Fusion theory has helped clarify the role of feelings of shared essence, both biological and experiential, in fusing together personal and group identities. And it has allowed researchers to test a host of predictions about the causes and consequences of this for ingroup cooperation and intergroup conflict. This chapter considers how the evolution of the imagistic mode may have benefited ancestral groups, and the individuals belonging to them, but in modern times, it has helped to fuel some of the deadliest forms of violence the world has ever seen.

IDENTITY FUSION THEORY AND EXTREME PRO-GROUP BEHAVIORS: THE CASE OF DISSIDENT POLITICAL PARTY SUPPORTERS IN TURKEY

This research was conducted with dissident political parties' supporters that were represented in the parliament of Turkey via 2015 parliamentary election. Using the Identity Fusion Theory, the study aims to explore the relations of people with local in-group (supporters of the supported political party) and extended in-group (citizens of the Republic of Turkey); and test the endorsement of extreme behaviors as fighting or sacrificing own life to save in-group members or improve the current conditions of in-group. Accordingly, data was collected from Republican People's Party (CHP; N = 320), Peoples' Democratic Party (HDP; N = 215), and Nationalist Movement Party (MHP; N = 150) supporters. There were significant group differences on study variables based on one's political party identity. Broadly, local in-group based socio-psychological processes were stronger in samples of HDP, MHP, and CHP supporters, respectively whereas extended in-group based socio-psychological processes were stronger in samples of MHP, CHP, and HDP supporters, respectively. Moreover, local in-group and extended in-group based socio-psychological processes were positively associated with each other in samples of CHP, and MHP supporters; but not associated in sample of HDP supporters. Identity fusion with local in-group indicated positive indirect (mediational) associations with endorsement of extreme behaviors for the sake of local in-group and extended in-group in three samples. The research findings complement the related literature, and present a relatively new theoretical approach to explain extreme pro-group behaviors.

Let Others Buy First: Identity Fusion Buffers the Effect of COVID-19 Phobia on Panic Buying Behavior From an Economic Perspective

The coronavirus 2019 (COVID-19) pandemic has caused hundreds of millions of cases and millions of deaths, resulting in the development of COVID-19 phobia. To prevent getting COVID-19, Centers for Disease Control and Prevention (CDC) in many countries encourage people to protect themselves via several strategies, such as wearing face masks or using sanitizers when washing hands. However, at times, such supplies for preventing COVID-19 are limited. In this study, we examine the relationship between COVID-19 phobia and panic buying behavior from an economic perspective and test if identity fusion plays a buffering role for this phenomenon. Data was collected from September 4th to November 1st in 2020 across three countries (the United States, Germany, and Taiwan). A self-report measure of panic buying behavior was developed and culturally cross-validated. Moderation analyses were conducted focusing on the study objectives. Results show that the economic factor in COVID-19 phobia predicts panic buying behavior, and this effect is buffered by identity fusion. It is worthy to note that this buffering effect emerged only in the Taiwanese sample, not in the American or German samples. Implications of identity fusion theory in human behavior are discussed.

Why some Muslims Engaged in Violence: A militarised Mentality

Since 9/11 countering different types of violence through CVE and PVE programs have become a central policy concern for many in the Western and non-Western countries such as the UK, France, the United States and Indonesia. These countries have launched various CVE and PVE programs to prevent what scholars call radicalisation and de-radicalise those dammed to have been radicalised. These programs' focus is often to build community resilience and persuade individuals to adopt a liberal or state-oriented understanding of Islam. However, how successful these programs are is not clear. In some cases, these programs have been counterproductive because they have fostered Islamophobia and mistrust, as is the case with the UK's Prevent strategy. This paper will take the UK as a case study and propose a non-religious conceptual framework by using strain and fusion theory and interview data to explain why some British Muslims decided to engage in terrorism. In doing so, the paper will argue that if the UK government is to prevent such decisions, it needs to focus on addressing the socio-political causes that engender motivations to engage in terrorism.

Human Language as a Natural Artifact of Planetary-Noospheric Mind: Coevolutionary-Macromutational Reinterpretation

The article discusses a new hypothesis of coevolutionary-macromutational origin of human language, through the prism of which this planetary-noospheric phenomenon is proposed to be considered as a natural artifact of holisticsynergetic coevolution of nature, society and culture. The following assumption has been suggested: the proposed hypothetical idea is a resonance of the former two philosophical theories: the fusion theory and the thesis theory, which were regarded by scientists either as natural or artificial (conventional / conditional) nature of human language. At the same time, they did not completely deny the origin of the human language as a result of various types of activities. The represented arguments helped to confirm the views of anthropologists, culturologists and other scholars. The creation of various artifacts (tangible and intangible) took place in all stages of evolution: geogenesis – biogenesis – psychogenesis – anthropogenesis and at a subsequent stage of Homo sapiens. However, language as the most important product of global evolutionism was formed at the stage of anthropogenesis, in particular as a corollary to the molecular mutations of human brain. The term “coevolution” has been transferred to the sphere of linguoanthropogenesis. In conjunction with the hypothesis of macromutation the natural artifact origin of human language is consistently explained under the scenario of biogenesis – sociogenesis – culturogenesis. The essence of the hypothetical result is that a qualitatively new driving force for the continuation of this scenario can be noospherogenesis, which is determined by historical and cultural development of mankind, its activities in all spheres of life and, most importantly, by the planetary high-tech mind.

Fractionally Charged Anyon Generated by Topological Path Fusion in Magnetic Flux Lattice

Anyon usually exists as collective excitation of two dimensional electron gas subjected to strong magnetic field, carrying fractional charges and exotic statistical character beyond fermion and boson. Fractional quantum Hall effect (FQHE) is the only experimental system showing solid evidence of anyon and a serial of fractional charges so far. Searching for new serial of fractional charges in FQHE or other physical system is still a challenge for both theoretical and experimental study. Here a topological fusion theory of propagating paths winding around a pair of fluxes is proposed to explore the physical origin of fractional charges. This topological path fusion theory not only generated all of the existed serial of fractional charges in FQHE and found the exact correspondence between FQHE and integral quantum Hall effect (IQHE), but also predicted new serial of fractional charges in FQHE. Further more, serial irrational charges like $2/(3+\sqrt{2})$ in one dimensional lattice of magnetic fluxes as well as that in two dimensional lattice of magnetic fluxes, such as $(1+\sqrt{2})$, are predicted. Even in three dimensional network of magnetic fluxes, a serial of fractionally charged anyon is predicted by this topological path fusion theory, which has exactly correspondence with the knot lattice model of anyon. In fact, in a multi-connected space time without magnetic field, this topological path fusion theory still holds, revealing an universal existence of fractional charge and mass in quantum material with strong confinement of particles (such as photonic crystal with porous nano-structures) and paving a new way for topological quantum computation.
