Abstract: Based on stakeholders’ appealing to colleges, university teachers should perform their duties as teachers well. A qualified and effective teacher should not only possess the basic quality, but also possess certain degree of “maturity”. According to the Argyris Theory of Maturity, this paper illustrates college teachers’ execution of duty from two aspects: the former, job maturity, expresses in talent cultivation, scientific research and social service; the latter, psychology maturity, in professional honor and responsibility. The picture of social responsibilities that teachers need to perform will provide university teachers some guidance on performance assessment of work, and offer a framework of thinking to effectively meet the demands of stakeholders as well.

Abstract: This paper focuses on the robust H¥ control problem for a class of fuzzy stochastic Markovian jump systems. The system under study involves with uncertain Markovian jump parameters, time delays, and uncertain transition probabilities. Firstly, based on free-weighting matrix method, a new fuzzy control design scheme via state feedback is proposed in terms of linear matrix inequalities. Then, the method of robust H¥ control is developed which is dependent on the size of the delay. Designed controller can guarantee asymptotically stable in mean square and a prescribed H¥ performance level of the resulting closed-loop system for all admissible uncertainties and time delay. Finally a numerical example is provided to illustrate the effectiveness of the proposed methods.

Abstract: With the widely universal attention of information security at present, the identification technology based on a kind of biological feature has already become relatively mature, such as, fingerprints identification, face recognition or iris recognition[1-3]. However, because of the singleness and limitation, this paper proposes a multi-biometric identification technology which adopts finger contour feature and palm prints feature to use different feature extraction methods to corresponding areas during the treatment process. Firstly, do the pre-treatment to images and get finger contour, and then extract finger length and average width and palm prints feature. We choose Gabor filter to extract feature of palm’s quadrate region in order to improve algorithm’s speed. Finally, adopt multi-layer matcher to make this system have higher identification precision and guarantee the identification security of system which makes up for the deficiency of single identification method greatly.

Abstract: In this paper, a new intersection theorem for weakly transfer compactly closed valued mappings is established in topological spaces. As applications, new variational inequalities, a fixed point theorem and a maximal element theorem are obtained in noncompact GFC-spaces. Our results unify, improve and generalize some known results in recent reference. Finally, equilibrium existence theorems for abstract economies and qualitative games in noncompact GFC-spaces are yielded.

Abstract: Urban green spaces have social, planning, economic and ecological functions. To benefit functions of green spaces, it is important to make sufficient provision of quality and quantity green space within urban areas. Using RS, GIS and based on the Quickbird image of Shenyang in 2008, this paper analyzed the urban green space landscape pattern at patch composition, class level and landscape level. This study combined gradient analysis with landscape metrics, and aimed to quantify the spatial pattern of urban green space in Shenyang city. The gradient analysis combined the landscape metrics and its spatial characters along the transect of urban green space based on the effects of spatial extend. The results showed that the distribution of urban green space was not uniform and the structure was not reasonable. It was also suggested that a spatial extent of 5 km might be more appropriate for urban green space pattern analysis by landscape metrics changing among different window sizes. Results demonstrated that the signi?cantly altered green space pattern could be quanti?ed using landscape metrics in each local area. In comparison with quantifying metrics in entire landscapes, Gradient analysis undertaken in four directions would be a robust tool to study the spatial pattern of urban green space.
