We use energy minimization principles to predict the structure of a decagonal quasicrystal–d(AlCoNi)–in the cobalt-rich phase. Monte Carlo methods are then used to explore configurations while relaxation and molecular dynamics are used to obtain a more realistic structure once a low-energy configuration has been found. We find five-fold symmetric decagons 12.8?Å in diameter as the characteristic formation of this composition, along with smaller pseudo-five-fold symmetric clusters filling the spaces between the decagons. We use our method to make comparisons with a recent experimental approximant structure model from Sugiyama et al. (K. Sugiyama, S. Nishimura and K. Hiraga, J. Alloy Comp. 342 65 (2002)).  相似文献

This study examines whether climate strength has a direct, moderating, or curvilinear effect in the relationship between service climate and customer service quality perceptions. To this end, we carried out cross-sectional and lagged empirical studies in the Spanish hospitality sector. Our cross-sectional results confirmed that high climate strength in managerial practices fosters a positive impact of managerial practices on customer service quality evaluations. However, other results related to customer orientation of services question the idea that service climate strength is always a precursor of service quality. High climate strength in customer orientation enhanced the negative relationship between customer orientation and functional service quality in a cross-sectional study, and between customer orientation and relational service quality in a lagged study. In addition, an examination of curvilinear effects of climate strength revealed an inverted U-shaped relationship between climate strength in customer orientation and relational service quality over time. The article concludes with a discussion of these results.  相似文献

According to Koffka (1935), the lightness of a target surface is determined by the relationship between the target and the illumination frame of reference to which it belongs. However, each scene contains numerous illumination frames, and judging each one separately would lead to an enormous amount of computing. Grouping those frames that are in the same illumination would simplify the computation. We report a series of experiments demonstrating that nonadjacent regions of the visual field under the same illumination level are perceptually grouped together and function, to some extent, as a single framework. A small coplanar group of patches under its own illumination exhibits compression of perceived range of gray shades. We obtained the reduction in compression in the presence of an identically illuminated 25-patch Mondrian tableau mounted nearby the coplanar group. The influence of the Mondrian display was reduced when it was (a) moved laterally away from the test display, (b) moved farther back in depth from the test display, or (c) rotated to a different orientation.  相似文献

The present paper is a generalization and further development of the theory of Kernel measures of reducibility axioms formulated in [1], [2], [3] in. the years 1969–1973. In this paper logical connections of Kernel measures with some set-theoretical notions are studied and some suggestions related to these connections are formulated.  相似文献

The article deals with phenomenology in Lithuania. The main thesis of the article is this: phenomenology is a living tradition in need of both development and interpretation. The minor thesis follows from the main one: the Western phenomenological tradition and Lithuanian philosophy interact and develop in tandem with one another. According to the authors, the contact between poetics and philosophy is the dominant form of phenomenology in Lithuania. The phenomenological tradition is treated as creative and living philosophical thought.
