Orchestra is proposed to change the traditional design process of routing protocols and it firstly introduces the concept of evolution into routing design. The disadvantage of traditional genetic algorithm, such as the bad searching quality and long computation time, makes the Orchestra has a bad performance and can not be applied to large scale network routing design. To improve Orchestra, a distributed...
With the deterioration of electronic environment, using signals DOA (direction of arrival) parameters has great significance to preselect multiple radar pulses. Cluster analysis as an important means of data classification, is gradually applied to radar signal sorting. In this paper, a novel method of signal sorting flowsheet is proposed based on Fuzzy Clustering to sort emitters DOA as data objects,...
In this paper we describe a new approach to distinguish and extract text from images with various objects and complex backgrounds. The goal of our approach is to present characters in images with clear background and without other objects. The proposed approach mainly includes two steps. Firstly, a density-based clustering method is employed to segment candidate characters by integrating spatial connectivity...
To improve the efficiency of the arc length (AL) algorithm, the paper presents a quantitative method to choose the parameters of AL. The paper analyzes the condition to guarantee the correctness of AL, and gives the approaches to set the parameters. Moreover, the latency of AL under the new method is discussed in detail. The analysis and simulation shows that the latency of AL with the parameters...
