The LiDAR system can be equipped on an aircraft to collect geographic information in a wide area. One characteristic of the LiDAR system is that it usually produces huge volumes of data. Thus, how to efficiently manage, store, process and visualize the LiDAR data sources has become an important and challenging research issue in the spatial database community. In this paper, we propose a distributed algorithm to process a remarkable spatial query (i.e., range queries) over massive LiDAR data points. Different from existing range query processing approaches which assume all data points are stored in a centralized server, our method adopts a decentralized fashion. Our query processing system is a master/slave architecture. A large data set is split into smaller partitions that are distributed among several slave machines. Therefore, each slave machine only process a small part of data points. We also develop index structures over LiDAR data sets to further enhance the efficiency of query processing. Our performance study proves the efficiency of the design.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122367525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Real geometry object could facilitate and consolidate students' geometry learning if students were given opportunities to apply and practice geometric concepts in authentic contexts. Geometry is one of the important subject, however, students have less opportunities to apply geometric concepts and solve geometry problems in authentic contexts. Therefore, we aimed to investigate the effect of UG app on students' geometry estimation ability, geometry learning achievement, spatial ability and geometric concepts and explore correlations among them. Participants were 82 fifth grade students divided into experiment group (EG), ruler measurement group (RG) and control group (CG). The results revealed that EG performed significantly better than RG and CG in geometry estimation ability, geometry learning achievement, spatial ability and geometric concepts. Beside the significant correlations between geometry learning achievement and spatial ability, we also found geometry estimation ability significantly related to spatial ability and geometry learning achievement which means fostering estimation ability through measuring authentic objects could help students' geometry learning. It indicated that UG app was able to enhance student's geometry estimation ability, geometry learning achievement, spatial ability and geometric concepts effectively.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121886810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a case study of Police Forensic Science Center 4, Khon Kaen, Thailand, an inquiry official used to report details of crime scene to Crime Scene Notification (CSN) center by telephone when a crime happened. After the service officer received notice case and wrote it on paper which may cause data loss and may take time to inquire more information. The process causes delayed data and unorganized storage, as a consequence; smartphones or tablets were utilized to solve these problems. This research proposes a development of a notification system for the crime scene investigation on android devices and web application. This system facilitates form-filling, file-recording, saving multimedia files, geographical search, navigation, and push notification message. The system allows the operation of the staff to be more convenient and the data to be orderly stored. The result shows that an average usability of web application was 76.65 while mobile application was 76.25. The result of the satisfaction evaluation of both systems was at a good level. Therefore, the developed system can be applied. It's an added way to be notified anytime and anywhere. As a result, the overall performance is more effective.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133643333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While MOOCs have shown successful in bringing online education up to the next level in developed country such as USA; such realization is barely observed in developing countries such as Thailand. With many failed attempts to establish MOOCs in Thailand, doubts often arise whether MOOCs would be the right platform that would mitigate the problems of the existing educational system in such a nation. In this paper, we first provide the history of MOOCs in Thailand. Then we discuss some of the major challenges that prevent such an online learning platform to thrive in Thailand, compared to those offline classroom-based educational programs. Furthermore, we present a comprehensive investigation of MOOC development in nearby countries such as Japan and Malaysia. Finally, both direct and indirect opportunities that successful MOOCs can offer are discussed, that focuses on the Thailand educational settings.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129581958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
