The multi-attribute evaluation methodology is utilized to address the issue of the TE in which the tactic features of the detected target are treated as evaluation attributes. Meanwhile, the intuitionistic fuzzy set (IFS) is employed to deal with information uncertainty in the TE process. Furthermore, on the basis of the entropy weight and inclusion-comparison probability, a hybrid TE method is developed. In order to accommodate the demands of naturalistic decision making, the proposed method allows air defense commanders to express their intuitive opinions besides incorporating into the threat features of the detected target. An illustrative example is provided to indicate the feasibility and advantage of the proposed method.展开更多

Historically, the roles of financial/accounting theory and cognitive psychology have been extensively studied and documented in attempting to explain individual financial decision-making. More recently, neuroscience has made substantial contributions to learning how prospective financial decisions and outcomes affect brain activity and observed decision-making behavior. The evidence from neuroscience indicates that up to 90% of our decisions are initiated at the unconscious level, which is only beginning to be investigated in a systematic manner. Integrating these findings from multiple disciplines, including recent contributions from neuroscience, has many implications, not only with respect to personal and corporate financial decisions and how markets work, but also as an essential component in the tool box of the general decision maker.展开更多

First of all, we study how to express a variety of graphics, and establish the definition of cell intuitive model, work out the cell intuitive operation process and many new cellular operators such as a variety of matrix blocks crossover operator, a variety of matrix blocks mutation operator, matrix blocks replace operator, matrix blocks compression operator, matrix blocks extension operator. By choosing two or more cells and selecting the artificial selection or fitness selection, we can set up and visualize the design and pick the best design results .Finally, validation is made on this algorithm by an example, and a innovation graphic is also represented.展开更多

In his seminal work Hooke and the Law of Universal Gravitation: A Reappraisal of a Reappraisal Richard S. Westfall argues that Hooke could not reach beyond the concept of spatially bounded particular gravities, as he deployed the method of analogy between the material principle of congruity and incongruity and the extension of gravitational spheres and their action at a distance. However, the doctrine of universal gravitation does not exclude the nature of particular gravities; it is predicated on the notion of an infinite expansion of individual-gravitational spheres and their uniform nature, namely the mutual and centripetal attraction. In my treatise 1 attempt to reinvestigate the nature and structure of gravitation, as established historically in the framework of Newtonian Classical Mechanics, by a method of structural intuition. It examines how the structural intuition, as represented in the celestial-mechanical intuitions of Hooke and Kepler, could unfold into an innovative process within the context of early modem mechanical philosophy, attaining thus a historical siglaificance and legitimacy as against the prevailing Newtonian method of geometric-mathematical axiomatization of mechanical principles. It also explores the actual demonstrative features of the tidal phenomenon with regard to its lunar- and solar-gravitational causation, which has been considered to date to be an important piece of empirical evidence for the theory of universal gravitation.展开更多

The study aims at investigating some second language learners' meta-linguistic ability in solving multidimensional grammatical problems. The subjects of the present study were 40 Egyptian students who were in their fourth year of academic study in the Department of English and Literature, Faculty of Arts, Menufia University, Egypt. The instrument of this study consisted of pre-test, post-test and individual interviews. Two tasks were used: (1) "Sentence Completion" task; and (2) "Error Recognition and Correction" task. Finally, students were interviewed to explain and comment on their performance in the previous tasks. The data were analyzed both quantitatively and qualitatively. Results were obtained and conclusions were made.展开更多
