As more and more structured documents, such as SGML or XML documents become available on the Web, there is a growing demand to develop effective structured document retrieval which...
Abstract. We study the problem of dynamic load-balancing on hierarchical platforms. In particular, we consider applications involving heavy communications on a distributed platform...
In this paper, we present a secure group key management scheme for hierarchical mobile ad-hoc networks. Our approach aims to improve both scalability and survivability of group ke...
In this paper, we propose a hierarchical classifier structure for gender classification based on facial images by reducing the complexity of the original problem. In the proposed f...
A second-order hierarchical uncertainty model of a system of independent random variables is studied in the paper. It is shown that the complex nonlinear optimization problem for ...
