FogGIS: Fog Computing for Geospatial Big Data Analytics

Cloud Geographic Information Systems (GIS) has emerged as a tool for analysis, processing and transmission of geospatial data. The Fog computing is a paradigm where Fog devices help to increase throughput and reduce latency at the edge of the client. This paper developed a Fog-based framework named Fog GIS for mining analytics from geospatial data. We built a prototype using Intel Edison, an embedded microprocessor. We validated the FogGIS by doing preliminary analysis. including compression, and overlay analysis. Results showed that Fog computing hold a great promise for analysis of geospatial data. We used several open source compression techniques for reducing the transmission to the cloud.Comment: 6 pages, 4 figures, 1 table, 3rd IEEE Uttar Pradesh Section International Conference on Electrical, Computer and Electronics (09-11 December, 2016) Indian Institute of Technology (Banaras Hindu University) Varanasi, Indi

3D Data Processing Toward Maintenance and Conservation. The Integrated Digital Documentation of Casa de Vidro

During the last decade, 3D integrated surveys and BIM modelling procedures have greatly improved the overall knowledge on some Brazilian Modernist buildings. In this framework, the Casa de Vidro 3D survey carried out by DIAPReM centre at Ferrara University, beside the important outputs, analysis and researches achieved from the point cloud database processing, was also useful to test several awareness increasing activities in cooperation with local stakeholders. The first digital documentation test of the Casa de Vidro allowed verifying the feasibility of a full survey on the building towards the restoration and possible placement of new architectures into the garden as an archive-museum of the Lina Bo and P.M. Bardi Foundation. Later, full 3D integrated survey and diagnostic analysis were carried out to achieve the total digital documentation of the house sponsored by the Keeping it Modern initiative of Getty Foundation (Los Angeles). Following its characteristics, the survey had to take into consideration the different architectural features, up to the relationship of architecture and nature. These 3D documentation activities and the point cloud processing allowed several analysis in a multidisciplinary framework

A review of tertiary BIM education for advanced engineering communication with visualization

SPECT with Tc-99m-labeled agents is better able to detect viability after nitrate administration. Nitrates induce vasoclilation and may increase blood flow to severely hypoperfused but viable myocardium, thereby enhancing tracer delivery and improving the detection of viability. Quantitative data on the changes in blood flow are lacking in SPECT but can be provided by PET. The aim of the present study was to use PET to evaluate whether nitrate administration increases blood flow to chronically dysfunctional but viable myocardium. Methods: N-13-Ammonia PET was used to quantitatively assess blood flow, and F-18-FDG PET was used as the gold standard to detect viable myocardium. Twenty-five patients with chronic ischemic left ventricular dysfunction underwent N-13-ammonia PET at rest and after nitrate administration. Results: A significant increase in nitrate-enhanced blood flow was observed in viable segments (from 0.55 +/- 0.15 to 0.68 +/- 0.24 mL/min/g, P <0.05). No statistically significant change in blood flow was observed in nonviable segments (0.60 +/- 0.20 vs. 0.55 +/- 0.18 mL/min/g). A ratio of at least 1.1 for nitrate-enhanced flow to resting flow allowed optimal detection of viable myocardium, yielding a sensitivity of 82% with a specificity of 100%. Conclusion: N-13-Ammonia PET showed a significant increase in nitrate-enhanced blood flow in viable myocardium, whereas blood flow remained unchanged after nitrate administration in nonviable myocardium. Nitrate use during myocardial perfusion imaging will lead to improved assessment of myocardial viability

GIS visualization of population censuses in Peninsular Malaysia: a case study of Jempol, Negeri Sembilan, 1947-2000

Census has become an important administrative tool for governments to trace and plan for national progress since it contains essential information about the populations. Studies of economics, sociology, history, rural development, and agriculture commonly used censuses. Nevertheless, these studies mostly focus on the textual and numerical analysis of the census data without paying much attention to the sense of space of the censuses. Hence, Geographic Information System (GIS) could help by enabling population censuses to be spatially visualized and analyzed. In this study, two common techniques in GIS were used to spatially visualize human population censuses of Jempol district, Negeri Sembilan in the 20th century. Using GIS, the available population census data of the district were transformed into choropleth and cartogram maps of population density. The two types of map were then compared based on their usefulness and appearance in visualizing the censuses. It was found that each type of maps has its own strengths and weaknesses, but overall, the application of GIS has been found to be an exciting and reliable medium for the spatial analysis and visualization of the censuses. The findings suggest that GIS adds another dimension in understanding past demographic phenomena in the study area. It is recommended that further research in this area, such as overlapping the spatial analysis with topographic elevations and socio-economic characteristics, as well as constructing linear and non-contiguous cartograms, should be conducted. Besides enhancing the spatial analysis of the censuses, this research paves way for the development of Historical GIS studies in Malaysia

Informatics Research Institute (IRIS) July 2004 newsletter

This summer period has been rich in presence and dissemination related activities. Several important conferences, which have enjoyed a great international participation and success, have been organized by IRIS academics in Salford. These include NLDB04, CRIS 2004 and the LTSN workshop. Also, a substantial number of research projects have been secured from national as well as European funding sources. All these activities are contributing to reinforcing the leading position that IRIS is currently enjoying in the field of Informatics. This newsletter gives an overview of all research activities that took place during this reporting period. It is hoped that this will help trigger further collaboration with existing and future colleagues from academia, research and industry to work together towards addressing the many societal and technological challenges engendered by the information age

Reynolds Number Effects on Wind Flows around Hemispherical Domes by Visualization Technique

[[abstract]]In general, visualization experiment in a conventional boundary layer wind tunnel for buildings is a difficult task to carry out. This research intends to conduct the visualization experiment through the direct observation on the surrounding wind flow. The occurrence of flow separation along the surface is preliminarily observed. By high-speed camera, the location of the separation point moves forward to the downstream as the Reynolds number increases.[[conferencetype]]國際[[conferencedate]]20130519~20130523[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]Tainan, Taiwa
