Evaluating fuzzy clustering for relevance-based information access
The experiments with various test document sets have shown that in most cases fuzzy clustering performs better than the hard k-Means algorithm and that the fuzzy membership values can be used to determine document relevance and to control the amount of information retrieved to the user.
Adaptive Sampling Mechanisms in Sensor Networks
This paper is looking at means of making an adaptive control mechanism to change the frequency of measurements by each node, as an alternative to non-adaptive fixed sampling rates.
Active Platform Security through Intrusion Detection Using Naïve Bayesian Network for Anomaly Detection
This paper presents the application of Bayesian technology in the development of an anomaly detection system for proxylets that will be incorporated into the Intrusion Detection System (IDS) that will provide runtime security to ensure active platform integrity is maintained while running third party executable codes.

The spatial aspect of this data handling requirement is met by creating clusters in a sensor network based on the rate of change of an oceanographic signal with respect to space.
Dynamic Knowledge Representation for e-Learning Applications
A modified version of the Fuzzy c-Means algorithm that replaces the Euclidean norm by a dissimilarity function is proposed for document clustering, which shows substantial improvement in the modified algorithm, both in terms of computational efficiency and of quality of the clusters.

A novel approach, based on gossip protocols and firefly synchronisation theory, for the management policy distribution and synchronisation over a number of nodes in an application level active network (ALAN), which is presented in the context of the IST project ANDROID.

It is shown how this design process leads to a sensor network system that is robust to topological changes, is scaleable and self-organising and has a number of other desirable features.
Applying UML to Design an Inter-domain Service Management Application
We present a component-oriented approach to demonstrate the use of the Unified Modeling Language (UML) and Open Distributed Processing (ODP) concepts to design service components of a…
Policy-Based Resource Management for Application Level Active Networks
This work develops resource models and metrics that take into account three categories: bandwidth, memory and processing in an active networking environment and defines the necessary classes of policies in order to achieve efficient resource management.
On power-laws in SDH transport networks
Evidence is presented for similar power laws also existing in transport layer topologies in a real world deployed SDH network, the possible effects of the physical layer and the extent to which the topology remains scale-free throughout the network's hierarchy.
