Several issues which should be paid attention to in mathematical contests have been discussed in this paper, which aims at increasing teaching efficiency through participating in mathematical contests.
The product sales are affected normally by the seasonal cycle, and the new product sales are nonlinearity in general. According to the characteristics of financial equipments sales, fixed weights model and variable weights combination prediction model are proposed based on traditional seasonal index smoothing prediction and grey system prediction, aiming at to minimize the error sum of squares.

In china, many regional higher education institutes(RHEIs), such as regional university, be founded from 2000. Those regional higher education institutes should improving their quality of teaching and learning. In this paper, we study analyses internet - based teaching and learning issues at regional higher education (RHE) level and efforts to devise a strategy as solution to those issues as a result...
State education institutes are believed as catalyst for the middle-education of any country. In china, many regional higher normal education institutes (RHEIs), such as regional university, be founded from 2000. Some graduate of those regional higher education institutes be the middle-school teacher. Those regional higher education institutes should improving their quality of teaching and learning...
Technologies are fast advancing around the globe, and new knowledge is being generated at all time. E-learning is to integrate technologies and new knowledge to allow learners to learn new knowledge at anytime and anywhere without constraints of time and space. With the increasing prevalence of e-learning, many cram school operators have released their own instructions based on e-learning methods,...
We propose a morphological quantitative evaluation method for the aging analysis of the handback skin. First of all, the non-invasive method of digital imaging technology is adopted to get the handback skin morphological data. Then, based on the algorithms of gray-level co-occurrence matrix and displacement co-occurrence matrix, morphological features of the individual handback skins are measured...
In this paper we suppose the formation and evolvement mechanism of city system is the site selection of special entities in the city. We construct model to simulate the mechanism based on multi-agent system, the experiment results show that the distribution of a virtual city system can be generated by the mechanism. Further, we prove that the generated distribution of city system is corresponding...
Mathematical Modeling and Visualization is a planned course of a new B.S. program in Computational Mathematics at Embry-Riddle Aeronautical University. Modeling methodology, formal process, modeling languages and software tools such as MatLab, Stella and Statemate will be integrated in this course to demonstrate the combined strength of mathematical formality and visual intuitiveness for conquering...
