The rapid growth in everyday products which rely on electronic, communication and software technologies has largely driven a worldwide expansion of research in related disciplines. Today the average person has come to expect ever-increasing functionality from cheaper and cheaper high technology products. Current research in computer-based product development relies heavily on the availability of software tools for the design and testing of next-generation products.
Professor Brinson’s current research interests centre on the development of software tools for modelling and performance testing of established and emerging technologies. Since 2006, he has been a member of the Quite Universal Circuit Simulator (QUCS) development team, specialising in device and circuit modelling, testing and document preparation. QUCS is an open source sourceforge.net project of which primary mission is the development of a software package licensed under the GNU Public Licence (GPL) for circuit simulator, compact device modelling and circuit macromodelling from DC to RF and beyond.
His current research activity is concentrating on the development of VHDL, Verilog and Verilog-A component models linked to C++ based circuit simulator code via XML interfaces. Emerging CMOS, optical, thermal and mechanical technologies are also forcing new approaches to the software engineering of circuit simulators and their related graphical user interfaces. Work on these technologies and their successful integration within the framework of a universal circuit simulator forms the central core of his present research interests and proposed activities in the near future.

The traditional way to improve the security of wired computer networks is by applying access control policies to the front door of network. However these policies are not sufficient and effective when applied to the Wireless Local Area Networks (WLANs). WLANs are different from the traditional wired LANs in terms of their exposure to potential threats, vulnerability and security techniques. Intrusions to WLANs have proliferated exponentially and handling such threats is becoming more and more difficult to eradicate. Dr Salekzamankhani has developed a standardised reference model to design, compare and evaluate the existing or future Intrusion Handling Systems (IHSs) for WLANs. His research work focuses on intrusion and denial-of-service detection: development of efficient, cost-effective and scalable techniques for detection of intrusion and denial-of-service attacks.
Hassan Nabijou

One of the most important applications of signal processing, in particular statistical signal processing, is in the telecommunications industry. A great deal of research work worldwide is dedicated to addressing problems associated with the transmission, coding, modelling and detection of signals and systems in global communication networks. Current research projects Dr Nabijou is involved with are in the fields of:
- speech recognition
- noise reduction
- channel equalisation
- acoustic noise control
- echo cancellation
Dr Nabijou is addressing these problems by means of higher-order statistics and non-linear system modelling using Volterra functional series.
