- Belief modeling for maritime surveillance
- Proceedings of 12th International Conference on Information Fusion, 2009, FUSION '09 in Seattle, WA, USA, 6-9 July 2009. In maritime surveillance, the volume of information to be processed is very large and there is a great deal of uncertainty about the data. There are many vessels at sea at every point in time, and the vast majority of them pose no threat to security. Sifting through all of the benign activity to find unusual activities is a difficult problem. The problem is made even more difficult by the fact that the available data about vessel activities is both incomplete and inconsistent. In order to manage this uncertainty, automated anomaly detection software can be very useful in the early detection of threats to security. This paper introduces a high-level architecture for an anomaly detection system based on a formal model of beliefs with respect to each entity in some domain of interest. In this framework, the system has beliefs about the intentions of each vessel in the maritime domain. If the vessel behaves in an unexpected manner, these intentions are revised and a human operations centre worker is notified. This approach is flexible, scalable, and easily manages inconsistent information. Moreover, the approach has the pragmatic advantage that it uses expert information to inform decision making, but the required information is easily obtained through simple ranking exercises., Conference paper, Published.

- Bluetooth for decoy systems
- Proceedings of 2017 IEEE Conference on Communications and Network Security (CNS) in Las Vegas, NV, USA, USA, 9-11 Oct. 2017. We present an approach to tracking the behaviour of an attacker on a decoy system, where the decoy communicates with the real system only through low energy bluetooth. The result is a low-cost solution that does not interrupt the live system, while limiting potential damage. The attacker has no way to detect that they are being monitored, while their actions are being logged for further investigation. The system has been physically implemented using Raspberry PI and Arduino boards to replicate practical performance., Conference paper, Published.

- Low voltage distribution substation integration in smart Microgrid
- Proceeding of IEEE 8th Conference on PowerElectronics, Jeju Island, South Korea, June 2011. A strategy is proposed to introduce a limited set of monitoring and control functions into a legacy low voltage distribution substation, and as such integrate it into a larger command and control architecture of a smart Microgrid. The focus of the work shall be on the retrofit strategy of some of the key components for measurement, monitoring, protection and control systems of the substation. Also Volt/VAR optimization of the feeder shall be considered as a part of the design. The article discusses the structure of the substation under study, followed by the actual design of IEC 61850 subsystems for the substation. A simulation model of the pilot project and its results is also included in the paper., Conference paper, Published.
