Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
A singularly perturbed reaction-diffusion problem with mix boundary conditions is solved numerically by using an adaptive grid method. The mesh is constructed adaptively by a grid generation algorithm. A linear and a semi-linear examples are tested. It is shown from the numerical results that the presented method is very efficient.
3D seabed terrain is established by the improved fractal interpolation algorithm. By adopting moving surface idea and making use of the local self-similarity of seabed terrain, this method maps rectangular subfield which consists of the cells around the centre interpolated cell to the interpolated cell by using fractal interpolation. In the seabed terrain establishment process, elevation is used to...
In this article, we consider the problem of construction of Probabilistic Boolean Networks (PBNs). Previous works have shown that Boolean Networks (BNs) and PBNs have many potential applications in modeling genetic regulatory networks and credit default data. A PBN can be considered as a Markov chain process and the construction of a PBN is an inverse problem. Given the transition probability matrix...
The performance of Cubature Kalman Filter (CKF) will degrade seriously when the theoretical model and real model are not matched due to change of target motion. To solve this problem, a new strong tracking square root CKF algorithm is proposed in this paper. Suboptimal multiple fading factors are used in the proposed method, which can adjust the structural parameters of the filter, and improve the...
In order to solve the problem of slow convergence of the basic firefly algorithm, a modified method was proposed. In the modified firefly algorithm, the parameters of the algorithm can be adjusted adaptively according to the lightness variance of the firefly population. And the random movement step can be determined in accordance with the distance of two fly flies. Meanwhile, the method of autonomous...
This paper analyzed the meaning of international business and characteristic of international business, basing on the Monte Carlo established a optimization model for international business strategic of power grid enterprise, and then estimated the possibility and sensitivity of a power grid enterprise.
In the Smart grid, network security is the important part. In this paper, we will introduce a new method detection based on Support Vector Machines to detect Masquerade attack, and test it and other methods on the dataset from keyboard commands on a UNIX platform. The presence of shared tuples would cause many attacks in this dataset to be difficultly detected, just as other researchers shown. In...
At present, the study of complex networks include the geometric nature of the network, the formation mechanism of the network, the statistical law of the network evolution, the model property on the network, the structure stability of the network, and other issues like network evolution and dynamic mechanics, etc. There into, in the field of natural science, the basic measuring of the network research...
In the development of Poisson mixed-effects model (PMM), it is assumed that the distribution of random effects is normal. The normality assumption is likely to be violated in many practical researches. In this paper, we develop a semi parametric Bayesian approach for PMM by using a truncated and centered Dirichlet process (TCDP) prior to specify the distribution of random effects. A hybrid algorithm...
A difference exists between the software testing environment and operating environment, which has a crucial impact on the software reliability assessment, testing costs and optimal release time. The software cost model is an effective tool used to help software developers control software costs and determine the release time. However, the current studies have not taken the difference of the environment...
In this paper, a international strategy model for electric enterprise was constructed, and was applied to estimated the possibility and sensitivity of a electric enterprise. At last, some conclusion and suggestion were drawn.
We investigate the radicals of Chinese character based on complex network theory. In this paper, in the study of Chinese character network, scale-free effect and hierarchical structure features are found in this complex system. In addition, we study the community structure in Chinese character network, and two interesting results have been obtained: First, the relationship between the node number...
