Abstract: Color space conversion (CSC) is a compute-intensive time-consuming operation in the area of image and video processing applications including video compression. Several hardware and software implementations for CSC have been found and that have both its good and bad sides. Multicore processors, especially programmable GPUs, provide an opportunity to increase the performance of CSC by exploiting data parallelism. In this paper, we present an efficient implementation of color space conversion suitable for heterogeneous multicore GPUs. Our experiments results show that the speedup of up to 17× can been obtained. Speedup performance is relevant to GPUs compute capability such as the number of scalar-processor, the block and grid sizes, and can be influenced by data transmission between CPUs and GPUs.

Abstract: This article carried on the research to the traveling present situation of Xingguo country through the questionnaire survey. The results show that the tourism environment system of Xingguo is good. However, tourism resources have the features of a low rich degree, general quality and without many characteristic. The overall economic level of Xingguo County is common, even in a relatively backward level, and the consumption level of residents is also low. This situation will hinder the rapid and sustainable development of the tourism. The overall evaluation of the tourism resources is general, and Xingguo County's tourism has not been really developed. In the end, according to the current situation of tourism in Xingguo County, the countermeasures for the tourism development were put forward.

Abstract: With the rapid development of science and technology, there is a growing number of researchers are designing a multiple input multiple output (MIMO) wireless powered communication network (WPCN) to realize a cooperative transmission with information and energy, in order to avoid the interference between multi-users. It is of great importance to design a low complex system for improving the efficiency energy. Therefore, based on the forefathers, this paper introduces the model of MIMO system, a “Harvest-then-transmit” protocol and the mathematical model of system.

A Qualitative Research of Influence Factors of the NGO Volunteers Erosion Base on Grounded Theory

Chaomin Gaoa, Jinfei Zhangb

College of Business Administration of Baise University, Baise, China

Abstract: In this paper, we use the qualitative research method of grounded theory to analyze the influence factors. Building the degree of NGO volunteers service model (MHC) to reflect the volunteers’ erosion mechanism, through analyzing the interviews Data of the 21 Chinese NGO volunteers. MHC model shows that: (1) The service motivation of volunteers come from  five demands which will affect the incentives, such as expanding the scope of the social and self-actualization; (2) when the service training, team building and so on seven factors the organization provided is not sufficient, volunteers’ Willingness to participate in service will be reduced; (3) the third is volunteer service will decided jointly by incentive effect and health care effect; (4)Volunteers’ service level decided by service will and objective conditions.

Abstract: As a very efficient tool, π calculus could do modeling and make evaluations effectively particularly by targeting the features of concurrency and mobility which quite commonly exist in the software system nowadays.  After a brief introduction of π comparison, this paper mainly discusses a comparison algorithm based on π comparison which is frequently used in the software modeling. As the ways of data storage mainly concern about random storage of elements and linked list storage of elements, this paper analyzes the algorithm of comparing any two elements in both ways. Particularly, the efficiency analysis is carried on to the element comparing algorithm in the linked list storage, which is relatively complicated, finding that the designed algorithm in this paper is greatly improved not only in algorithm simplification but also in working efficiency.

Chaoqun Sun, Jianhua Wang

Research Center of Geotechnical and Structural Engineering, Shandong University, Jinan, China

Abstract: Considering the combined effects of water pressure and mining disturbance, the failure characteristics of coal seam floor under mining pressure and stress variation are simulated by using ANSYS software. Model is established according to the actual data. Floor failure characteristics under different advancing distance are simulated. The results show that the failure of the bottom is constantly changing with the advancing of the working face. With the expanding of the mining area, the depth of floor failure is increasing, which makes the crack expand and connect, that will lead to inrush water from floor. Numerical simulation for mining simulation analysis and prediction is feasible. The research results can provide reference for the process of fluid-solid coupling analysis and water inrush mechanism of coal mining.

Jie Hu

School of Communication and Information Engineering, Chongqing University of Posts and Telecommunications, Chongqing, China

Abstract: Current privacy preserving for data publishing techniques concentrate on tables with Euclidean distance. However, most of real world data have relevance, if the clustering process did not considering this factor, will cause a high probability of attack based on background knowledge. This paper will discusses the real world data association, and then propose a privacy preserving approach-based data association on the idea of traditional clustering algorithm. Frist, analysis and calculate the correlation coefficient between inter-attribute, then clustering based on Mahalanobis distance. In addition, to against the difficult of centroid select, options based on centroid clustering processes are further proposed. The result show that the probability of being attacked by using privacy preserving approaches-based data association, the effect of protection against background knowledge attack will be reduced at least 10% in comparison with traditional kmeans algorithm. The privacy preserving approaches can better balance the published data’s security and availability, being feasible and effective.
