The complex Swift-Hohenberg equation models pattern formation arising from an oscillatory instability with a finite wave number at onset and finds applications in lasers, optical parametric oscillators, and photorefractive oscillators. We show that with real coefficients this equation exhibits two classes of localized states: localized in amplitude only or localized in both amplitude and phase....

University scientific research ability is an important indicator to express the strength of universities. In this paper, the evaluation of university scientific research ability is investigated based on the output of sci-tech papers. Four university alliances from North America, UK, Australia, and China, are selected as the case study of the university scientific research evaluation. Data comin...

It is meaningful for colleges to evaluate teaching staff annually. This paper developed a method to make fuzzy evaluation of teaching staff based on Fuzzy Comprehensive Evaluation Technique (FCE). The main idea is getting experts’ opinions for proposed evaluation criteria, calculating the most appropriate weights to the criteria based on combination between AHP and Entropy methods, rating stude...

Identification and management the 'critical risk areas' where hotspot lead exposures are a potential risk to human health, become a major focus of public health efforts in China. But the knowledge of health risk assessment of lead pollution at regional and national scales is still limited in China. In this paper, under the guidance of 'sources-pathways-receptors' framework, regional human healt...

The evaluation model on technical innovation ability of small and medium enterprises is set up based on analytic hierarchy process and fuzzy comprehensive evaluation methods, which takes quantitative index as main parts and considers reality so that better practicability is obtained. Meanwhile, technical innovation ability of small and medium enterprises in Heilongjiang Province of China are ob...

In this article, we applied the AHP method with quantitative analysis and qualitative analysis to analyze three sorts of basic educational mode combining production with learning and research, i.e. the automated instruction, the mode combining production and learning, and the integration combining production with learning and research, and obtained that the educational mode combining production...

In evaluating construction investments, public or private sector owners often have several project alternatives, e.g. different sites for development and different types of building. Assessing each of them so as to identify the best for implementation is owners’ most important decision in the project planning stage. The traditional net present worth method has difficulty in including intangible...

Background. In England, people with a serious mental illness are offered a standardized care plan under the Care Programme Approach (CPA). A crisis plan is a mandatory part of this standard; however, the quality and in particular the level of individualisation of these crisis plans are unknown. In this context, the aim of this study was to assess the quality of crisis planning and the impact of...

We present core data structures and algorithms for matching graph patterns with general recursion. Our approach uses magic sets, a well-known technique from deductive databases, which combines fixpoint-based bottom-up query evaluation with top-down handling of input parameters. Furthermore, this technique is enhanced with the global search plans, thus non-recursive calls are always flattened be...
