In recent years, cloud computing has been an important issue in the field of research. Cloud computing employs distributed storage and distributed computing technology to achieve a large number of stored data, as well as fast data analysis and processing. As the rapid development of Internet technology, digital data showing explosive growth, the face of massive data processing, the traditional text software and relational database technology has been facing a bottleneck, presented the results are not very satisfactory. For this problem, the concept of cloud computing is a more appropriate choice. In this paper, based on the architecture of Hadoop with HDFS (Hadoop Distributed File System) and Hadoop MapReduce software framework and Pig Latin language, we design and implement an enterprise Web log analysis system. Experimental results, by analyzing daily Web log records, we get Application Server traffic trends, performance of program statistical reports, and performance reports of different intervals and different actions of program by user request. The main purpose of this system is to assist system administrators to quickly capture and analyze data hidden in the massive potential value, thus providing an important basis for business decisions.

This paper proposes a image in painting method for stereoscopic images based on hole-classification. The stereoscopic image pairs and their depth map images are generated by left and right shifting the original image according to its corresponding depth information. The generated left and right image may have disocclued areas or holes in the image after shifting operation. In this paper, disocclued areas or holes are classified into three type, gradient, clear-cut and layer and three different filling routes and filling methods are adopted according to these three types of holes. From the experimental results, it is proved that holes maybe mistakenly filled have been in painted with better corrections, in the meantime, in painted image becomes more natural and closer to the reality when it is viewed.

The literatures have indicated that cooperative learning facilitates enhancing learning performance, which focuses on (1) the interaction and the collaboration between grouping members, and (2) one member helping other members to be successful. The literatures have shown that the grouping organization is a critical issue for promoting learning achievement in cooperative learning. To evaluate the differences between the self-organized groups and the designated groups, this paper has conducted a serial of experiments and assessments to study the differences of learning performance, participation and satisfaction degree. In the self-organized groups the grouping members are decided by the grouping members, whereas the grouping members in the designated group are composited of the considering conditions. The experiment have demonstrated that the learning achievement of the designated group is high than the self-organized group. For the participation and the satisfaction degree of the curriculum, the self-organized group is high than the designated group.

The purposes of this study were two folds. First was to design three strategies to help elementary school children reading science expositories online with the supports of an annotation system. The "iRuns" strategies were proposed based on the SOI model of Reading expository text [1] to include (1)"underline" for selecting main ideas, (2)"annotation for connection" to organize important ideas and (3)"summary" for integrating multiple concepts. Then a field study was conducted to explore whether students efficiently adopted iRuns strategies and achieved comprehension on earth science materials. A total of 55 5th and 6th graders from an elementary school participated a 8-week reading club. A plug-in annotation system (COM2ANNO) developed by Huang et al. [2] was adopdeted. Students' underlying, annotation and summary efficiencies were rated more favorable if they hit more main ideas. The results showed that iRuns strategy efficiencies decreased slightly across multiple time points and the high reading ability students' three annotation efficiencies were always better than the low ones. The gaps of iRun strategy efficiencies between high and low reading ability groups was gradually getting closer through series of instruction. Low ability students' strategy efficiencies correlated with comprehension score significantly but the high ones didn't. It indicated that low reading ability students benefited greatly from the iRuns strategies instruction. The annotation efficiecy was affected by using different types of annotating method (type vs. Copy-paste). Typing resulted in shorter annotations while copy-pasting produced better quality of annotation which demonstrated more highly relevant main ideas selected across texts.

This study intends to design a distance assessment system for preschool kids with autism spectrum disorder (ASD). This system is an improvement of the past system that was used in previous research. For the demand of future research and the increasing size of the sample size, the technical challenges, occurred in the past system that associated with internet problems, have to be solved. The limitation of the resources such as professionals in special education (teachers), time, space, and cost will be considered in designing this system. Moreover, the need of distance assessment for prescreening children with ASD also related to the difficulties for ASD kids to get used to a new environment such as early invention center, school, and hospital. This study will focus on overcoming the technical challenges associated with the internet-based transmission to provide the option of taking tests remotely and to broaden the application of the assessment. Therefore, this paper has designed a distance system that use cloud server system to solve the limitation of server storage and slow Internet connection. Webcam function also is included to direct and instruct the students in conducting the assessment and teacher can record whole assessment progress to collect the data.

At present, most of the GPU MapReduce frameworks are based on single multimedia processing program, and cannot be used to handle multiple multimedia processing programs simultaneously. The service needs for multiple multimedia processing programs can only be satisfied by sequencing, which lacks efficient data segmentation and resource scheduling management. As a result, the hardware efficiency is reduced under the multiple multimedia processing programs. Based on the existing MapReduce framework of GPU, Mars, this study designed a parallel processing mechanism for multiple multimedia processing programs. According to the processing needs of current multimedia processing programs, hardware resources demand, and data processing capacity, the proposed mechanism segments the large quantity of data produced by multiple multimedia processing programs, and transmits the suitable work load segments according to the hardware loading capacity for further processing. This study uses the multimedia processing program, which is commonly used for MapReduce framework computation, as the experimental work load, and treats the execution time as the index for the efficiency improvement. The results suggest that the average processing speed under the proposed mechanism is improved by 1.3 times.

In this paper we aim to create new effective computer model for distinguishing Asian people by their face using frontal face part color, size and distances based on comparative research about image processing and face recognition. It is difficult to determine face part size and distance due to image quality, lighting condition, rotation angle and facial emotion. Hence, first we need to detect face on the image then convert image into real input. After that we can determine image candidate's gender, face shape, key points and face parts. Finally, we will return the result, based on comparison of sizes and distances with the sample's measurement table database. While we were measuring samples, there were big differences between images by their gender and face shapes. Input images must be the frontal face image that has smooth lighting and does not have any rotation angel. The model can be used in military, police, defense, health care, and technology sectors.

Regular computer networking courses normally include individual laboratory tasks for each student, because the course's main objectives require that each student have the ability to manage all network equipments as an administrator. However, this approach still suffers the limitation of an insufficient amount of equipment in laboratory classes. We applied collaborative virtualization-based experimentation (CVE) in this study to avoid this limitation. CVE enables students to do networking assignments such as connecting, design, configuration, testing, and troubleshooting using the Linux OS on a group of virtual machines (VMs) connected to a single server. Collaborative tasks for laboratory assignments in CVE have the following rules: 1) each student manages and configures one VM, 2) students can establish laboratory network setups by connecting with other group members' VMs, and 3) students can communicate with others via online synchronous discussion (OSD). The students in the experiment were divided into a control group and an experimental group. The experimental group performed their laboratory assignments using CVE, whereas the control group completed the same assignments on VMs that were installed on their personal computers. The results show that the experimental group significantly outperformed the control group in the last two homework assignments and the second post-test. In addition, the experimental group's activities were better than those of the control group, based on the total average of the command count per laboratory. Finally, the analysis of the questionnaire data of the experimental group reveals that CVE was helpful during and after the laboratory class, including when the students performed laboratory assignments.
