The local burning velocity and the flame displacement speed are the dominant properties in the mechanism of turbulent premixed combustion. The flame displacement speed and the local burning velocity have been investigated separately, because the flame displacement speed can be used for the discussion of flame-turbulence interactions and the local burning velocity can be used for the discussion of the inner structure of turbulent premixed flames. In this study, to establish the basis for the discussion on the effects of turbulence (...) on the inner structure of turbulent premixed flames, the indirect relationship between the flame displacement speed and the local burning velocity was investigated by the flame stretch, the flame curvature, and the tangential strain rate using DNS database with different density ratios. It was found that for the local tangential strain rate and the local flame curvature, the local burning velocity and the flame displacement speed had the opposite correlations in each density ratio case. Therefore, it is considered that the local burning velocity and the flame displacement speed have a negative correlation. (shrink)

The flame displacement speed is one of the major characteristics in turbulent premixed flames. The flame displacement speed is experimentally obtained from the displacement normal to the flame surface, while it is numerically evaluated by the transport equation of the flame surface. The flame displacement speeds obtained both experimentally and numerically cannot be compared directly because their definitions are different. In this study, two kinds of experimental flame displacement speeds—involving the mean inflow velocity and the local flow velocity—were simulated using (...) the DNS data with the different Lewis numbers, and were compared with the numerical flame displacement speed. The simulated experimental flame displacement speed involving the mean inflow velocity had no correlation with the numerical flame displacement speed, while the simulated displacement speed involving the local flow velocity had a clear correlation with the numerical displacement speed in the cases of higher Lewis number than unity. The correlation coefficient of the simulated displacement speed involving the local flow velocity with the numerical displacement speed had a maximum value on the isosurface of the reaction progress variable with the maximum temperature gradient where the dilation effect of the flame is strongest.

This study examined the determinants of trust in artificial intelligence (AI) in the area of asset management. Many studies of risk perception have found that value similarity determines trust in risk managers. Some studies have demonstrated that value similarity also influences trust in AI. AI is currently employed in a diverse range of domains, including asset management. However, little is known about the factors that influence trust in asset management-related AI. We developed an investment game and examined whether shared investing (...) strategy with an AI advisor increased the participants’ trust in the AI. In this study, questionnaire data were analyzed (n=101), and it was revealed that shared investing strategy had no significant effect on the participants’ trust in AI. In addition, it had no effect on behavioral trust. Perceived ability had significantly positive effects on both subjective and behavioral trust. This paper also discusses the empirical implications of the findings. (shrink)

Recentes estudos em história da ciência têm apresentado indícios de que é impossível estabelecer uma clara distinção entre estudos de óptica e de perspectiva linear quando nos referimos aos séculos XVI e XVII. Embora a perspectiva linear lidasse com a representação geométrica do espaço numa superfície bidimensional, estava, entretanto, estreitamente ligada a questões relativas à natureza da visão humana. Devemos considerar que, naquela época, o termo perspectiva era a tradução latina da palavra grega optikè, denotando a visão direta e distinta (...) que, para os gregos, revelava as coisas. Seu significado coexistiu com outros que designavam a técnica pictórica e, para distingui-los, era comum opor a perspectiva "comum” ou “natural” à perspectiva artificialis dos pintores. Essas diferentes expressões de perspetiva relacionaram-se de diferentes maneiras, cobrindo um largo espectro de possibilidades. Contudo, à medida em que se encerrou o século XVI, essas duas expressões de conhecimento passaram, gradativamente, a se referir a diferentes disciplinas. Parte desse processo esteve ligado às novas práticas matemáticas em que a óptica, a geometria e as artes buscaram redefinir seus campos de investigação, considerando questões de ordem teórica ligadas à visualização e à representação do espaço. Neste artigo, apresentamos alguns aspectos da estreita conexão entre perspectiva naturalis e artificialis, tendo por base um conjunto de documentos relativos à óptica e à perspectiva linear publicado nos séculos XVI e XVII.

the two-and-a-half years that Dewey lived in Japan and China offered him an East-West comparative standpoint to examine Euro-American presuppositions. In subsequent work, he took steps in the direction of a global philosophical outlook by promoting a fusion of aesthetic refinements with democratic experimentalism. The year 2021 marks the centennial of Dewey’s return to the United States, yet philosophers in this country have only begun to take in an emerging global philosophical scene that includes unfamiliar questions, angles, idioms, and emphases. (...) This includes American pragmatists. In a sense, as Gregory Pappas has observed in the context of Latin American philosophies, pragmatism did not “grow up” in the United... (shrink)

The culturally pervasive tendency to identify aspects of the body as aesthetically imperfect harms individuals and scaffolds injustice related to disability, race, gender, LGBTQ+ identities, and fatness. But abandoning the notion of imperfection may not respect people’s reasonable understandings of their own bodies. I examine the prospects for a practice of aesthetic assessment grounded in a notion of the body’s function. I argue that functional aesthetic assessment, to be respectful, requires understanding the body’s functions as complex, malleable, and determined by (...) the projects and interests of the person whose body it is. Aesthetically relevant functions, on this account, are determined neither by the body’s status as organism nor by cultural assumptions about how bodies should function or be used. (shrink)

This chapter will introduce everyday aesthetics and conceptions of happiness, explore their interconnections, and indicate some ways they might relate to depression. I introduce the main claims and concerns of everyday aesthetics and illustrate these with examples from the Indian, Chinese, and Japanese philosophical traditions. I then consider two popular accounts of happiness – ‘hedonic’ and ‘life-satisfaction’ theories – and offer an alternative phenomenological account of happiness. Aesthetic appreciation and agency and happiness, it is argued, depend on a phenomenologically fundamental (...) capacity to experience different kinds of significant possibility. It is the loss or disruption of that capacity which characterises experiences of depression. (shrink)

This reference essay surveys recent work in the emerging sub-discipline of everyday aesthetics, which builds on the work of John Dewey to resist sharp distinctions between art and non-art domains and argue that aesthetic concepts are properly applied to ordinary domains of experience.

When Dewey scholars and educational theorists appeal to the value of educative growth, what exactly do they mean? Is an individual's growth contingent on receiving a formal education? Is growth too abstract a goal for educators to pursue? Richard Rorty contended that the request for a “criterion of growth” is a mistake made by John Dewey's “conservative critics,” for it unnecessarily restricts the future “down to the size of the present.” Nonetheless, educational practitioners inspired by Dewey's educational writings may ask (...) Dewey scholars and educational theorists, “How do I facilitate growth in my classroom?” Here Shane Ralston asserts, in spite of Rorty's argument, that searching for a more concrete standard of Deweyan growth is perfectly legitimate. In this essay, Ralston reviews four recent books on Dewey's educational philosophy—Naoko Saito's The Gleam of Light: Moral Perfectionism and Education in Dewey and Emerson, Stephen Fishman and Lucille McCarthy's John Dewey and the Philosophy and Practice of Hope, and James Scott Johnston's Inquiry and Education: John Dewey and the Quest for Democracy and Deweyan Inquiry: From Educational Theory to Practice—and through his analysis identifies some possible ways for Dewey-inspired educators to make growth a more practical pedagogical ideal.
