The principle and method are given to build spatio-temporal database for mining land via analyzing the data storage modes in reality database and history database. Based on building thespatio-temporal...
This paper describes the design and implementation of a Web Geographical Information System (WebGIS) for government comprehensive emergency management, which is based on advanced technologies such as ...
In real life there are various types of information, not all information contains a clear geographical coordinates of the spatial information, a large portion of non-spatial information is relevant to...
Given a set P of n uncertain points on the real line, each rep-resented by its one-dimensional probability density function, we consider the problem of building data structures on P to answer range qu...
We consider the problem of allocating routes in multiple-commodity networks. In such networks, a user can directly download the ‘desired file from a server, or she can do this via a indirectly route t...
We explore the mechanism design problem for lung exchange and its implementation in practice. We prove that determining whether there exists a non-trivial solution of the lung exchangeproblem is NP-co...
We formulate and study the algorithmic mechanism design problem for a general class of resource allocation settings,where the center redistributes the private resources brought by individuals. Money t...
The computation of the global minimum energy conforma-tion (GMEC) is an important and challenging topic in structure-based computational protein design. In this paper, we propose a new protein design ...
Remote sensing change detection technique has been an important method to observe the land use change. At present, there are lots of algorithms of land use change detection, but there isn’tan existing...
The design of a multipurpose database, mainly as supporting tool for decision makers and public administrators, needs to consider social, economics and environmental factors, which relationships can b...
With the development of land and resources informatization, huge amounts of information resources has accumulated, but data between different departments is hard to share and utilize, the unitary effe...
One of the most important tools in order to model real world phenomena is Geographic Information System. Real world phenomena are changing continuously, so it is necessary to detect and introduce chan...
In Section 1, the background of the research is introduced. The Jiangsu Coastal Web Atlas is a project that has the ambitious goal of being a useful resource for the various audiences that make up the...
In the Greater Beijing metropolitan area of North China (Beijing-Tianjin-Hebei areas), a mixed single-and dual-frequency ground-based GPS water vapor monitoring network is established to support opera...
At present, as mobile devices like Personal Digital Assistant (PDA) or Handheld PC (HPC) are rapidly developed and the wireless Internet is increasingly used, interests in the mobile Geographic Inform...
