Spatial ability has been recognized as a significant human skill involving the retrieval, retention, and transformation of visual information in a special context. The enhancement of the spatial ability and the effective method of training are rarely considered as an area of study in the education field. This study focuses on the enhancement of spatial visualization and mental rotation, which a...

An effective method for the automatic classification of facial expressions into emotional categories is presented. The system is able to classify the user facial expression in terms of the six Ekman’s universal emotions (plus the neutral one), giving a membership confidence value to each emotional category. The method is capable of analysing any subject, male or female of any age and ethnicity....

To extract terminological knowledge from data, Baader and Distel have proposed an effective method that allows for the extraction of a base of all valid general concept inclusions of a given finite interpretation. In previous works, to be able to handle small amounts of errors in our data, we have extended this approach to also extract general concept inclusions which are “almost valid” in the ...

Motivated by the interest of observing the growth of cancer cells among normal living cells and exploring how galaxies and stars are truly formed, the objective of this paper is to introduce a rigorous and effective method for counting point-masses, determining their spatial locations, and computing their attributes. Based on computation of Hermite moments that are Fourier-invariant, our approa...

InventionTool 3.0, which is a CAI software based on TRIZ, is created by Institute of Innovation of Hebei University of' Technology. Using the CAI software, designers can solve innovation problem. During the design process, the InventionTools 3.0 plays a very important role. Firstly, the technical evolution module of the InventionTools 3.0, as an effective method, is used to obtained conceptual ...

We consider the individual points on a Martin-Löf random path of Brownian motion. We show (1) that Khintchine’s law of the iterated logarithm holds at almost all points; and (2) there exist points (besides the trivial example of the origin) having effective dimension < 1. The proof of (1) amounts essentially to showing for almost all times t, the path f is random relative to t and the dimension...

Knowledge is the essential source of enterprise competitive predominance. As the changes of the enterprise environment, the multinational corporation will pay more attention to the effective flow of knowledge and internal integration. But the cross-border transfer of the knowledge has many obstacles, especially the tacit knowledge sharing. As viewed from the tacit knowledge characteristic, it i...
