Abstract—Dijkstra algorithm can be adopted to distinguish different parts of boundaries in medical image segmentation problem, which can be a reference for further segmentation operation. However, classical Dijkstra algorithm can hardly adapt to real time image segmentation problem owing to its exponentially...

Abstract—To solve nonlinear non-Gaussian filter problems in target tracking, Gaussian mixture unscented particle filter with adaptive residual resample algorithm is proposed. Gaussian mixture unscented particle filter is utilized as importance density to improve the estimation accuracy evidently. By...

Abstract—Cloud computing to provide service for the user group is huge, so the number of cloud computer’s tasks is enormous, the system handle large tasks all the time so that task scheduling is the key and difficult points in the cloud. This article make research on how to make full use of cloud resources...

Abstract—The accurate modeling of primary users (Pus) behavior is important and crucial to cognitive radio (CR). The method to detect idle frequencies, not used by primary users’ (Pus’) has been widely investigated recent years. Existing researches need to estimate and select the threshold of the energy...

Abstract—The modeling research is conducted in this thesis, according to the characters of the highway power-ground plane modeling and with the adoption of the vector fitting modeling method. The modeling of a real four-floor PCB power-ground plane is completed, via the comparisons of model time domain,...

Abstract–This paper devoted to the development of the coordinate system discontinuous transformation for the simulation of multiple groups periodic motion and their aerodynamic interaction. The proposed approach reduced to the creation a separate local coordinate system for each group of bodies that...

Abstract—The Chinese sentence similarity has been used widely in the field of Chinese information processing. There are many methods proposed to measure the similarity of Chinese sentences, but the accuracy of these methods is still lower. In order to improve this problem, this paper proposes an improved...

Abstract—This paper proposes a zero-watermarking algorithm of SVG vector map based on stroke-width characteristic. The algorithm takes the stroke-width as an important characteristic. By statistics, calculating and simplifing the stroke-width probability in SVG vector map, building a K-d characteristic...

Abstract—Taking unmanned aerial vehicles as background, this paper introduces a design method of a flexible master-slave working mode according to the thoughts of redundancy technology to improve the vehicles’ availability[1] in order to reduce the influence of the breakdown of vehicles caused by terrible...

Abstract—The weighted association rules mining is more significative than traditional association rules mining in practice. Allowing for the impact of the number and weight of property on association rules, this paper presents a new method of mining weighted association rules, which can hold the “downward...

Abstract—Based on the analysis of the path planning under the cyclic goods-taking model, the mathematical model of path planning is established. After comparison and analysis of the commonly-used optimization algorithms, the Ant Colony Optimization (ACO) is adopted to solve the path planning model under...

Abstract—Transboundary and cross-catchment access to ecohydrological data is the key to designing successful environmental policies and activities. Access to and visual representation of scientific information for the public is essential for attracting greater awareness of ecosystem matters. This requires...

Abstract—The extreme learning machine (ELM) that is proposed by Huang is designed based on single-hidden layer feedforward neural networks (SLFNs), which can randomly choose the parameters of hidden nodes and the output weights gotten analytically. So it can get the solution fastly. However, the learning...

Abstract—The purpose of this paper is to present some results on the development and verification of NUAA-ICE2D icing software code, which contains five separate program modules and a graphical user interface. Computational simulation of the ice accretion process on airfoils using multiple time-steps...

Abstract—Visual block languages have introduced new ways of learning computer languages. New Integrated development environments (IDEs) for standard programming languages such as C or SQL have been developed, derived from block languages and based on the metaphor of building blocks. New online IDEs,...

Abstract—By using the principle of partly least square to locate and value the gross errors in the observational data, the matrix equation of the adjustment model may have ill-posed problems, which results in the locations and evaluations of the gross error unreliable. For the observational data which...
