This study proposed a social capital (SC) model to examine the relational bonds between SC and the mathematical literacy (ML). A random sample of 1021 15-year old secondary school students responded to the SC Questionnaire measured in Likert scales rated from 1 (strongly disagree) to 10 (strongly agreed) and answered selected released 2006 PISA items on ML. Structural Equation Modeling was employed...
P2P (peer-to-peer), which means resource transferring between clients, is a new technology applied in file sharing, instant message and media streaming. Nowadays it's more and more popular for it supplies a low cost method for people to gain resources. Since its born P2P makes progress towards fully distributed model or hybrid model from central model.
Resource Discovery and Resource Selection are the crucial tasks in grid scheduling and resource management. The goal of resource discovery and selection is to identify list of authenticated resources that are available in the grid for job submission and to choose the best node. Recently adaptive push-pull method was proposed for information dissemination of information for dynamic web data. In this...
Nowadays search engines provide the easiest way to reach information resources that are available on the Web. The number of Internet users has been growing dramatically all over the world. Nevertheless, as for those who can not use computers and the Internet, mobile search engine plays a great role in offering the service. In this case, it quickly attracts people's attention because it is unique....
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
