The goal of ranking is to learn a real-valued ranking function that induces a ranking or ordering over an instance space. A learning algorithm is stable if the algorithm satisfies the hypothesis that the output of the algorithm varies in a limited way in response to small changes made to the training set This paper studies the 'almost everywhere' stability of ranking algorithms, notions of strong stability and weak stability for ranking algorithms are defined, and the generalization bounds of stable ranking algorithms are obtained. In particular, the relationship between strong (weak) loss stability and strong (weak) score stability is also discussed.

We proposed a new time-domain based method,sensitivity approach,for computing steady state response of nonlinear oscillators,which are described mathematically by a nonlinear state space *** this manner we avoid directly solving of nonlinear ordinary differential equations by discretization or linearization which can lead to low accuracy in resulted *** approach is very easy to use and only requires solving a sequence of linear differential equations.A test system is used to illustrate the efficiency of proposed methodology.

Ecosystem services and value evaluation have become research focus of ecology, ecological economics, environmental economics and other frontier fields;moreover, it is a national economic accounting and an important basis for market operations. At present, studies of ecosystem services falls far from what the nation needs. This paper summarizes progress of Chinese ecosystem services and valuation research during the past decade. We discussed some key issues and future directions in ecosystem services function. An aim of our paper is to provide ideas for the development of ecosystem services and evaluation research in China, and support a more detailed reference for government.

In this paper, successfully we had implemented Fant’s resampling algorithm by using cubic convolution for resampling the images that consists two passes. It does not exhibit the aliasing artifacts associated with techniques for spatial transform of discrete sampled images is possible through the use of a complete and continuous resampling interpolation algorithm. Applications to image processing include reconstruction, smoothing, enlargement and reduction.
