In radiation environments, alpha particles, cosmic rays and solar wind flux can cause a single event upset (SEU), which is one of the major sources of bit-flips in digital electronics. The control-flow checking is an effective way for the running systems to prevent the breaking-down caused by SEU. Control-flow checking by software signatures (CFCSS) and enhanced control-flow checking with assertions...
To analyze the linear correlations of numeric attributes of government data, this paper proposes a method based on the clustering algorithm. A clustering method is adopted to prune outliers and the linear correlation analysis is performed for each cluster, instead for the whole dataset. In this way, the method can obtain multiple correlations between the same two attributes. The paper presents the...
Association rules mining is one of the most important and fundamental problems in data mining. Recently, in need of security, more and more people are studying privacy- preserving association rules mining in distributed database. This paper addresses a secure mining algorithm of association rules, which builds a globe hash table to prune item-sets and incorporate cryptographic techniques to minimize...
Clustering techniques can be adopted to analyze 3D model database and improve the retrieval performance. However, 3D model database lack valuable prior knowledge. Thus, it becomes difficult for the clustering methods to pre-decide the appropriate parameter's value. Moreover, clustering methods are short at handling outliers by treating outliers as "noise". The paper introduces a robust hierarchical...
The complex mapping z larr za is important in dynamical application, but it is not received as much attention in the literature as the mapping z larr za+c, for there is not fractal structure by using escape time algorithm. This paper utilizes a new method named as distance ratio iteration method and discusses the iteration properties of the complex mapping z larr za. The distance ratio iteration method...
