Parallel computers can do more than simply speed up sequential computations. They are capable of nding solutions that are far better in quality than those obtained by sequential c...
Information Technology has changed our life and society already to such an extent that even our visions cannot exist without technology and its applications. And this change is acc...
A new combinatorial characterization of a gray-tone image called Euler Vector is proposed. Euler number of a binary image is a well-known topological feature, which remains invari...

The emergence of the world-wide-web has led to an increased interest in methods for searching for information. A key characteristic of many of the online document collections is t...
† To guarantee quality of service (QoS), the requirements for video transmission such as delay and cell loss rate (CLR) are very stringent. These constraints are difficult to mee...
Web-based Information Systems (WIS) are now widely used for diffusing and processing information over the network. Methodological guidelines which assist WIS developers in their t...
This paper introduces the notions of mask and multiple format for setting up a progressive access to information in an Information System. Masks consist of more or less complete r...
