Using entropy weight and TOPSIS method, a comprehensive evaluation is done on the development level of Chinese regional service industry in this paper. Firstly, based on existing research results, an evaluation index system is constructed from the scale of development, the industrial structure and the economic benefits. An evaluation model is then built up based on entropy weight and TOPSIS, an...

Plant has plenty use in foodstuff, medicine and industry. And it is also vitally important for environmental protection. However, it is an important and difficult task to recognize plant species on earth. Designing a convenient and automatic recognition system of plants is necessary and useful since it can facilitate fast classifying plants, and understanding and managing them. In this paper, a...

Upper and lower regression models (dual possibilistic models) are proposed for data analysis with crisp inputs and interval or fuzzy outputs. Based on the given data, the dual possibilistic models can be derived from upper and lower directions, respectively, where the inclusion relationship between these two models holds. Thus, the inherent uncertainty existing in the given phenomenon can be ap...

In this paper we investigate the parallel difference schemes of parabolic equation, in particular, two kinds of difference schemes with intrinsic parallelism are constructed. Firstly we combine the values of previous two time levels at the interface points to get the (Dirichlet) boundary condition for the sub-domain problems. Then the values in the sub-domains are calculated by fully implicit s...

This paper explains the concept of temporal convergence in the context of the time-value of knowledge. We explore epistemological aspects of knowledge/information management through notions of human cognitive awareness and mental models by which we may share situational knowledge and common intentions. We explore the temporal relationships of information (lag, reiteration, timeliness, lifetime ...

The equivalence between autonomicity and the absence of free variables is a well-known result for linear, shift-invariant and complete behaviors over a field. However, this no longer holds for a behavior that does not satisfy one of those properties. In this paper we consider linear, shift-invariant and complete behaviors over the ring Zpr and study under which conditions such behaviors are aut...

Recent advances in technology have resulted in huge increases in the flow of information to human operators in complex operational environments. Most current interfaces present the information via visual displays, thus placing great demands on the visual information processing capacity of the operator. In an effort to lessen these demands, a great deal of research has been focused on the feasib...

The paper compares properties of 3 approximate confidence intervals on the variance component corresponding to the random factor in a general case of a mixed linear model with two variance components, supposing only that more than a minimum number of observations is available. Namely, relationships between intervals suggested by Park and Burdick [6], Hartung and Knapp [5] and Thomas and Hultqui...

Simulation of human behavior in space is a powerful research method to advance our understanding of the interaction between people and their environment. It allows for both the examination and testing of models and their underlying theory of cognitive and perceptual phenomena as well as the observation of the system’s behavior. This paper outlines the use of specific spatial objects to facilita...
