An emergency cartographic system named CartoEM using fundamental geographic data was proposed with the specifications for cartographic symbols to topographic maps and the existing GIS system and cartography system. The architecture and the data organization of the system were described. Then, some key issues of cartography with the system were investigated, such as cartographic representations, labeling,...
The study of map symbols is one of the basic problems of cartography. Map symbols and map symbol library is also one of the core issues of geographic information systems and mapping software. The varieties of GIS systems and mapping software have unusual map symbol definitions, different depicting ways, and different application purposes and approaches. It is a serious problem to share map symbol...
The design work is important to normal employment and safety and stabilization of a project in geotechnical engineering. The system researched in geotechnical engineering is altitudinal complex and indeterminate, so traditional design methods are difficult to deal with an actual project ideally. According to the characteristics of inverse design method in geotechnical engineering, the problems on...
In this paper, a numerical method (termed, E47 algorithm) based on linear variational inequalities (LVI) is presented and investigated to solve quadratic programming (QP) problems which are simultaneously subject to linear equality, inequality and bound constraints. Note that such constrained QP problems can be equivalent to linear variational inequalities and then to piecewise-linear projection equations...
As one of new type evolutionary computing methods, Mind Evolutionary Algorithm (MEA) processes evolutionary operations by using `similartax' and `dissimilation' operator. To improve the algorithmic convergence especially in the late evolutionary time, “information entropy” of populations is built to estimate the state of the evolution in a new self-adaptive MEA based on information entropy is proposed...
