In this paper, a variable-length counting Bloomfilter is studied for a variable-length-count Bloom filter(VLCBF) when configuring updates to the median groupfrequently-shifting. Our proposed improved VLCBF deleteseach hash value stored in the first buffer insertion. Only theauxiliary Bloom filter bit is modified accordingly until thebuffer is full when the group of digits updates a shift. Themethod...
To solve the network security response problem, a novel network response decision-making method based on the two-matrix game model was present. We analyzed the attackers and system administrators' different strategies, and then constructed the dual-benefit matrix of the attackers and defenders. On the basis of this, the two-matrix network security game model was proposed. At last, the optimal defense...
A large number of researches at home and abroad have indicated that patent data can play the role of quantitative analysis of measurement innovation activities excellently. This article has made quantitative analysis of patent factors in independent innovation pattern from the perspectives of patent quantity and quality based on summarizing the current measurement innovation activities of patent data...
By establishing a regional innovation capability evaluation index system and TOPSIS method on China's 30 provinces (municipalities) with statistics as well as the software of SPSS17.0, the article gave a comprehensive sort to the regional innovation capability of them, and made a detailed evaluation and analysis of the results.
Since chaos in economics been discovered, more and more chaos theory is applied to the study of economics and finance. Since the nineties of last century to the present, a lot of the financial crisis occurred, and even the global financial crisis, just like 2007-2008 global ciris. Many of the financial crisis, the phenomenon can be well explained by chaos theory, more and more people focus on how...
This paper presents an analysis of teaching quality improvement in college English language teaching using data mining for developing quality improvement strategies. Based on 1132 survey samples that were collected from a certain grade students during the period from April to June 2008, important factors impacting the teaching quality were identified via the decision tree method for data mining. Findings...
Network threat assessment is an important branch of information security assessment. Its research involves data fusion and data mining. This paper provided an overview of related research efforts in the area of network threat assessment. It presented a network threat assessment framework, and demonstrated a computational approach based on attribute recognition theory. In the computational example,...
It's necessary to create a credible and general evaluating index model in network threat assessment. According to the network indices' effect, this paper proposed an algorithm which combines grey correlation degree in grey theory with traditional analytic hierarchy process (AHP) to determine the indices. It considered both objective and subjective factors. Experiments showed that this method had a...
Employee turnover is one of the most durable issues in both organizational behavior research and human resource management practice. Although a great deal of employee turnover models has been well established, much of these researches have not considered the differences between occupation groups. In an effort to fill this theoretical gap, the present study attempted to provide an examination of a...
