In this paper, we first present a new concept of ‘weight’ for 64 triplets and define a different weight for each kind of triplet. Then, we give a novel 2D graphical representation for DNA sequences, which can transform a DNA sequence into a plot set to facilitate quantitative comparisons of DNA sequences. Thereafter, associating with a newly designed measure of similarity, we introduce a novel approach to make similarities/dissimilarities analysis of DNA sequences. Finally, the applications in similarities/dissimilarities analysis of the complete coding sequences of β-globin genes of 11 species illustrate the utilities of our newly proposed method.

The current network is designed for peak loads, which results in lower network resource utilization and great energy waste. In case of meeting the wireless coverage and user requirements, how to make more base stations in wireless networks into a sleeping state has become an important means of energy saving. Virtualization network technology makes it possible that centralized scheduling wireless network resources and deploying intelligent energy perception network. According to the characteristics of the underlying virtual network mapping and base station energy consumption situation, the virtual cell resource mapping multi-objective decision making energy saving model is proposed in this paper. And then, the two-step mapping algorithm is used for solving the model. At last, the results of theoretical analysis and simulation experiments show that this algorithm can effectively reduce the system energy consumption.
