Nowadays, data handled by an institution or company is spread out by more than one database and lots of documents of different types. To extract the information implicit in that data, it is necessary to pick parts from those various archives. To obtain a general overview, those information slices should be gather. Different approaches can be followed to achieve that integration, ranging from th...

reliable estimates of river stream fl ow and fl ood zoning maps are needed for water resourcesmanagement such as fl ood mitigation, water supply, dam construction and irrigation. flood zoning needsaccurate data and is one of the non-structural fl ood management methods. this paper describes theapplication of hec-ras and gis model to determine fl oodplains maps for the part of sardabrud rivertha...

self-affine maps were successfully used for edge detection, image segmentation, and contour extraction. they belong to the general category of patch-based methods. particularly, each self-affine map is defined by one pair of patches in the image domain. by minimizing the difference between these patches, the optimal translation vector of the self-affine map is obtained. almost all image process...

This paper describes the digitization and utilization of Complete Map of Peking, Qianlong Period, which is the oldest measured map of Beijing made about 250 years ago. We first proposed the geometric correction method called “linepreserving distance weighting method” to preserve linear features relevant in the old map of cities. Next we improved the reliability of the old map as information inf...

In E-Learning, the selection of the pedagogical contents to teach and the organization of this content are two principal operations during the design of a course. The growth and the diversity of the informational resources used generate problems of diffusion, access, of classification and management. With the MEMORAe project, we deal with these problems and propose to answer them by using an on...

This paper explores the idea of using contexts to support more efficient information search in Topic Maps-based digital libraries. The notion of context is perceived as abstraction of grouping of domain concepts and resources based on the existing semantic relationships between them. The proposed model of context is used for context representation in the TM4L environment.

Demands to make education flexible and active call for a comprehensive restructuring of the traditional university course format. We show how such restructuring can be done in a natural and coherent way by combining e-learning with Polyscopic Topic Maps, an information structuring method which is being developed by the authors. We describe a university course model called Flexplearn which is ba...
