nverse problems are important interdisciplinary subject, which receive more and more attention in recent years in the areas of mathematics, computer science, information science and other applied natural sciences. There is close relationship between inverse problems and ill-posedness. Regularization is an important strategy when computing the ill-posed problems to maintain the stability of the computation.This paper compares a new regularization method,which is called Adaptive regularization, with the traditional Tikhonov regularization method. The conclusion that Adaptive regularization method is a stronger regularization method than the traditional Tikhonov regularization method can be made by computing some numerical examples.
Starting with the generation of the software engineering, the development of software engineering is discussed in this paper. On this basis, we analyze the shortcomings in traditional software engineering courses. Especially for the characteristics of software engineering course in the non-computer professional, a new method is explored-practice-based teaching methods.
This paper studies this relationship between free trade and carbon dioxide emissions by utilizing the time series data collected from the year 1981 to 2009. The study shows: there's a long-term equilibrium relationship between trade liberalization and carbon dioxide emissions in China; a unidirectional causality exists from Foreign Trade Dependency to carbon dioxide emissions, while the causality between FDI Dependency and carbon dioxide emissions is bidirectional.
In order to determine the health status of Larix principis-rupprechtii plantation in the Eastern Inner Mongolia, the field data were surveyed and then the principal component analysis, mean-variance analysis method and fuzzy comprehensive evaluation method based on Fortran program were comprehensively applied to evaluate these forests in this study. Results showed that the health grade of Larix principis-rupprechtii plantation was 2.267. The health grade was between the sub-health and medium health, which was lean to the sub-health in the eastern Inner Mongolia.
