Data plays an important role in today's business activities. In order to share information, data is outsourced occasionally, usually in the form of Extensible Markup Language (XML) files which may contain sensitive information only intended for specific audiences. Securing the data is, as a result, of the utmost importance. Several techniques are used for this purpose, with encryption being the most powerful method. The major disadvantage of using encryption is that it reduces the performance of those queries which perform operations on encrypted data. In this paper we propose a technique that significantly improves the performance of range XQuery on encrypted XML data. Results show that the proposed technique is more efficient than the state-of-the-art technique.

Hadoop, a distributed system infrastructure, is developed by Apache Software Foundation and has become a mainstream platform of cloud-computing. How to improve one of its core frame work-MapReduce performance has become a hot topic. However, how to get a better computational performance is still a big challenge for programmers. It appears to be many visualization tools for performance analysis and optimization because of the research of display and analyze program performance by the aid of visualization technology is receiving more and more attention. This paper analyzed sorting performance in Map Phase of Hadoop System and proposed a method to optimize the sorting performance dynamically. It collected and analyzed ten visualization tools that are the most popular in the global world, and found that R language is the tool suited to Hadoop through comparison and analysis, and introduced the combination of R language and Hadoop. In the future, we will apply RHadoop to MapReduce performance optimization.

Previous studies have demonstrated that Concept Factorization (CF) have yielded impressive results for dimensionality reduction and data representation. However, it is difficult to get a desired result by using single layer concept factorization for some complex data, especially for ill-conditioned and badly scaled data. To improve the performance of the existing CF algorithms, in this paper, we proposed a novel clustering approach, called Multilayer Concept Factorization (MCF), for data representation. MCF is a cascade connection of L mixing subsystems to decompose the observation matrix iteratively in a number of layers. Meanwhile, we explore the corresponding update solutions of the MCF method to reduce the risk of getting stuck in local minima in non-convex alternating computations. Experimental results on document and face dataset demonstrate that our proposed method achieves better clustering performance in terms of accuracy and normalized mutual information in clustering.

FM-Index and Suffix Array are closely related to each other and are both extremely popular indexes for genomic sequences. They are used in several popular read alignment tools, including Bowtie, Bowtie 2, BWA, and GEM. In literature, there exist several Suffix Array Construction Algorithms (SACA). We have considered two popular SACA techniques: DivSufSort and SAIS. Both techniques construct suffix array in linear time. We have constructed FM-Index using both of these SACA algorithms. In this paper, we comprehensively describe our FM-Index construction approach and compare performance of these two indexes in terms of time for different string types in the Dataset. Our result shows that DivSufSort-based FM-Index performs 3.67% time efficient than SAIS-based FM-Index on 10 out of 11 strings in the Dataset.

The previous knowledge of the students at the beginning of a study at universities is more and more dissimilar. The traditional classroom teaching cannot cope with this heterogeneity. Therefore one has to find suitable methods to adjust the knowledge of all students to a reasonably similar level. In this paper we present some adequate methods and techniques, which can easily be integrated into the curriculum and additionally enable the students to be actively involved in the development of the implementation of these techniques.

The deformation of hydrostatic bearing rotary workbench is the direct factor that affects working accuracy. In this paper, taking the hydrostatic bearing rotary workbench as research object, the improvement model of the hydrostatic bearing workbench structure is established. In different speed conditions, thermal deformation calculation for workbench is conducted by using finite element method and fluid solid coupling technique. By comparison of the results of the model before and after the improvement, it is concluded that the thermal deformation of the workbench can be decreased if we add rib plate appropriately. Conclusion can provide guidance for the production of the hydrostatic bearing workbench, and it also has certain scientific significance to improve the accuracy of CNC machine tools.
