Research Projects

Artificial Intelligent Systems (AIS)

Artificial intelligent techniques are employed in modelling of DNA mismatch repair expression and microsatellite instability in transitional cell carcinoma of the bladder and to improve the accuracy of the bladder cancer prediction. These models are then compared with conventional statistics using experimental molecular biomarkers, including p53 and the mismatch repair proteins. Development of support system for anaesthesia monitoring and control based on hierarchical structure containing fuzzy reasoning adaptation, supervision, surgical evaluation and alarm conditioning is underway.  Different techniques based on signal processing, rule-based fuzzy logic control, wavelets, neuro-fuzzy modelling, genetic algorithms and real time control involving instrumentation interfaces will be pursued in the future. The research will also be undertaken to investigate implementation of smart, fuzzy and intelligent techniques for biomedical applications and development of blackboard intelligent system based on multi-agent control system for Cryogenic test equipment for electronics assessment, and Plasma Assisted Chemical Vapour Deposition.


The on going research in bio-nanotechnology is focused on the development of a fully integrated micromachined microfluidic device for point-of-care diagnostics. This is a nucleic acid detection system capable of accepting whole blood as a crude biological sample, followed by on-chip DNA extraction, purification, PCR amplification and electrochemical detection in a manner that allows for micro litre samples to be screened for infectious pathogens with sample-in-sample-out results in less than 30 minutes. The proof-of-concept of DNA extraction from whole blood has been successfully demonstrated using switching magnetic fields. Numerical modelling of a novel electrochemical DNA sensor has been completed and the proof-of-concept studies are underway. The research will continue to address the challenging issues associated with the system integration of all the functionalities including PCR, electronic control and embedded software. Future research will be directed towards system design modification to accommodate other biological samples. The application areas will be extended to bacterial, viral and fungi detection in food, forensic, bio-defence and veterinary environments.


Recently, biometric door-lock based on finger print technology was successfully completed in collaboration with an industrial partner. Research is being pursued in developing multimodal biometric fusion algorithms using fingerprint, voice and face recognition data. This will be further extended to incorporate wireless security and the fusion algorithms will be modified to achieve secure communication using cellular and WiMax networks in health care and commercial transaction applications.  Nanotechnology based fingerprint sensor with liveness detection based on sweat pore activity is being developed to improve authentication to achieve desired FAR and FRR. A further area of research is the study of chaotic behaviour in electronic circuits and the conditions for such behaviour. This offers potential for new data encryption strategies. Future research will also focus on the use of nanotechnology based antenna arrays to develop fingerprint sensor.

Charge Particle Dynamics (CPD)

The research activities in charge particle dynamics will continue with the focus on bipolar charge measurement of pharmaceutical aerosols. Intelligent drug dispensing devices will be developed using NEMS/MEMS technology in close collaboration with pharmaceutical industries. The existing lung deposition model will be further extended to incorporate 3-D alveolar region and implemented on a virtual reality cave. Electrohydrodynamics of nanospray formation and charge droplet stability will be investigated using Molecular Dynamic simulation. Electrokinetics of nanoparticles and biological molecules will be investigated to better understand material surface properties and interface phenomena.

Ultrasonic and Electromagnetic (NDT)

Guided wave ultrasound has been exploited for NDT in pipes, flexible risers, rails and sheet piles. Collaborative research is being pursued with an industrial partner to investigate propagation of dispersive modes and mode coupling in such structures. Focused beams and time reversal techniques are being exploited to minimise unwanted mode coupling. Advanced digital signal processing techniques are used to improve the resolution of crack detection based on guided wave ultrasonic signals. Research is also carried out to develop an embedded system based on Field Programmable Gate Arrays (FPGA).  Recent efforts have also been directed towards the data collection and signal processing of seismic data in order to seek precursors to earthquake activity.  A further avenue of research which is currently being pursued is the peizo-electric effect occurring in massive structures. Rocks in the earth's crust when subjected to stress, emit electromagnetic radiation. This can be detected at the earth's surface and research is underway to detect patterns in these emissions and correlate them with seismic activity. The same phenomenon is being exploited in the built environment to provide a non destructive testing approach to building structures.

Image and Vision Systems (IVS)

The main aim of this project is to develop a real time system based on multi-resolution statistical algorithms for medical image segmentation. 3-D medical image processing is a very computationally intensive process which leads to high power dissipation. A range of design methodologies and arithmetic techniques will be investigated such as distributed arithmetic and systolic arrays to reduce the area / time complexities and power dissipation in the system. The system will be tested and evaluated on different Field Programmable Gate Array (FPGA) platforms. Multiresolution and statistical algorithms such as wavelet/rigdlet transforms, and Gaussian Mixture Modelling (GMM) will be accelerated on reconfigurable hardware.

Reconfigurable Computing (RC)

Reconfigurable Computing and Image and Vision Systems research in CESR will focus on pioneering future directions and innovation in artificial vision systems through the integration of image/video processing software and hardware expertise. The research will include the development of a hardware accelerator for image processing algorithms based on matrix computations. Research efforts will be directed towards addressing the problem of processing large matrices using different design methodologies and arithmetic techniques in order to achieve improved area/speed ratios compared to existing systems. Applications that will be addressed are: face recognition for security and video surveillance, 3-D medical image segmentation and registration for tumour definition for radiation therapy planning and cancer diagnosis and information retrieval. We will aim to provide embedded hardware solutions and parallel low power architectures for computer vision applications using reconfigurable hardware.

Location Based Services

Research in GPS navigation has resulted in a patented system for blind navigation (Brunel Blind Location Based Service). Generally, LBS products should also satisfy most end users' requirements and incorporate privacy in the communication links. One of the main challenges of BBLBS is the performance of the received GPS data in terms of accuracy and precision; especially while navigating the blind in urban environments where availability of GPS signals is limited and high accuracy levels are needed. To overcome this difficulty, a new architecture is being implemented that is based on integrating several navigation systems. This architecture will extend the Differential GPS (DGPS) method to be used for wide area correction coverage using the Ordnance Survey GPS network. The wide area DGPS method will be integrated with wide area correction signals from EGNOS satellites and from the SISNET server. This hybrid system will work as an augmentation system that utilises the best available correction signal; thus increasing the reliability and integrity of Brunel Blind LBS System. Another complementary area of research that is being pursued is human factors in the design and control of system products, environment and services. Application of visual ethnography methods are used in user requirements.

Electronic Patient Record Systems (EPRS)

Obtaining extensive Electronic Patient Records (EPRs) at the point of delivery, together with the ability to search for and view vital, valuable, accurate and relevant EPRs fragments can be challenging. It is necessary to reduce redundancy, enhance the quality of medical decision making, decrease the time needed to navigate through very high numbers of EPRs.  Such a system will consequently promote the workflow and ease the extra work needed by clinicians. These demands were evaluated through introducing a system model named SVSEPRS (Searching and Viewing Segments of Electronic Patient Records Service) to enable healthcare providers supply high quality and more efficient services. SVSEPRS is a web-based system model that helps participant to search for and view virtual EPR segments, using an endowed and well structured Centralised Multidimensional Search Mapping (CMDSM), which defines different quantitative values (measures), and descriptive categories (dimensions), which allows clinicians to slice and dice or drill down to more detailed levels or roll up to higher levels to meet clinicians required fragment.

Evolable Hardware (EH)

Development of advanced software   and hardware- based multi-chip modern intelligent techniques for design and optimisation of logic circuits (mainly use of evolutionary computation and evolvable hardware). The developed system is able to design and optimise some parts of the logic circuits automatically without human participation on either software or hardware. Evolutionary design of logic circuits (so called evolvable hardware) is applied for both extrinsic (software-based) and intrinsic (hardware-based) systems. Evolvable hardware combines the use of evolutionary computation to design and optimise the combinational and analogue logic circuits. The approach has been significantly improved by use of bi-directional incremental evolution as well as unconstrained evolution.

Principles of Evolvable Hardware

This research is concerned with development of hybrid intelligent systems that are capable to solve relatively complex problems. The hybrid intelligent systems include combination of evolutionary computation techniques, bi-directional incremental evolution, fuzzy logic, neural networks, expert systems and swarm optimisation. The creative features of evolutionary computation are used to design 3D paths, wireless network and images.
