There has been a great development in Wireless GIS (WGIS) new century. Spatial data transferring and storage in GIS is developed from wired to wireless network. This paper first briefly introduces the technologies and strategies of spatial data transferring and storing in distributed Wireless GIS. Second, the schemes of spatial data transferring modes in wireless GIS for improving the network t...
The paper focuses on mapping the road network into 4-regular grid structures. A mapping algorithm is proposed. To model the road network GIS data have been used. The Geographic Information System (GIS) data for the road network are composed with different size of line segment lengths. The manipulation of the line segment length for mapping is analyzed. The algorithms and simulation results are ...
We consider the problem of determining how similar two networks (without known node-correspondences) are. This problem occurs frequently in real-world applications such as transfer learning and change detection. Many networksimilarity methods exist; and it is unclear how one should select from amongst them. We provide the first empirical study on the relationships between di↵erent networksimila...
Software Architecture design is to be a key step in the process of software development. For large and complex emergency network geographical information system in practice, it is ridiculous to achieve the goal of emergency management based on unsuitable software architecture. At present, the network geographical information system software architecture can be divided into four layers: display ...
Electrical Utility Network is the most generic term in the case of electrical transmission network, concerned in GIS environment. The network gets started from the source and ends with sink. The source is the generation point of electricity and the sink is the end point may be an industry / a small house where the energy is best utilized. This electric utility network is an energy process flow ...
High-dose ionizing radiation induces severe DNA damage in the epithelial stem cells in small intestinal crypts and causes gastrointestinal syndrome (GIS). Although the tumour suppressor p53 is a primary factor inducing death of crypt cells with DNA damage, its essential role in maintaining genome stability means inhibiting p53 to prevent GIS is not a viable strategy. Here we show that the innat...
With the construction of mobile communication network system, the need of building an integrated network management system based on specialized network management using GIS technologies become more and more necessary. By analyzing the current status of mobile communication network management system, this paper proposes that using ArcGIS, Java, Flex and other technologies to implement the integr...
Forecasting electric demand and its geographical distribution is a prerequisite to generate expansion planning scenarios for distribution planning. This paper presents a comprehensive methodology that uses a fuzzy inference model over a GIS support, to capture the behavior of influence factors on load growth patterns and map the potentia1 for development. The load growth is spread over maps wit...
Today information systems play key role in new century, geographical information system (GIS) as a special class of information system. Now we are moving wired to wireless network, that is mobile environment shown in fig2 (any where any time and any thing computing), plays key role in this new century. In this application mobile GIS, which will be a network environment, is proposed, which can p...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
