The limit of one variable function is an important problem in Higher Mathematics, it is a basic method to study the relationship between the function of variables. This template describes some important method about counting the limit, and gives the solving skills.

Based on the concept of traditional workflow and the thought of SaaS in cloud computing, puts forward a new concept named software service workflow. An application system based on this concept was built for processing marine resources automatic. This system put forward a visual customization interface...

In the interference cancellation system, the SAP (Sub band Affine Projection) algorithm is researched commonly, but the step size is given. In order to solve this problem, this paper puts forward an algorithm that can make the step size change with the variation of output error. The simulation results...

With the increasing scale of issue, the list planning performance remarkably decreases in the three-step method. To solve this issue, an improved granular algorithm is proposed in this paper for the C2 model design. At first, the adaptability measurement of model is optimized from the perspective of...

With the rapid development of internet, all kinds of information increases exponentially. It is different for users to find their requisite information because of the widely distributed information of internet. In ordered to provide timely, conveniently and efficiently to farmers the interested agricultural...

Interpersonal relationship plays a more and more important role in the real society. The study of relationship research algorithm is especially important .Based on the shortest path of graph theory and combined with the fact of the social network service (SNS) searching, the interpersonal closeness degree...

Surface restructure for triangulation discrete data was the preconditions for discrete data to be widely applied in modern manufacturing. Due to using multi-core processors and connected graph traversal access algorithm, put forward a new method of surface restructure for discrete data based on parallel...

At watermarking is developed, The construction proposed in this paper is based on a no subsampled pyramid (NSP) transform and wavelet transform (WT).The result of no subsampled transform is a flexible multiscaleand shift-invariant image decomposition that can be efficiently implemented via the à torus...

For the crack noise in molten-image processing of rock deformation experiment, this paper proposes an abnormal value detection method based on connected domain area, through the experiment of comparison with two-dimensional discrete Fourier transform method, this approach can not only completely remove...
