3D printing of fibre-reinforced cartilaginous templates for the regeneration of osteochondral defects
(2020)Successful osteochondral defect repair requires regenerating the subchondral bone whilst simultaneously promoting the development of an overlying layer of articular cartilage that is resistant to vascularization and ... -
Ad hoc Networking, Markov Random Fields, and Decision Making
(2006)Our central proposition is that by articulating decision making in an ad hoc network using a Markov random field (MRF) maximum a posteriori (MAP) approach, a viable decision- making framework can be designed. This ... -
Air jet cooling of brake discs
(Institution of Mechanical Engineers, 2008)This paper reports on an investigation of a novel approach to the cooling of brake discs, based on the application of impinging air jets. This has the capacity to enhance the heat transfer coefficients at the disc surface ... -
Applications and Opportunities for Cognitive Radio and Networks
(IEEE, 2012-07)we present three aspects of cognitive radio and networks of importance to the research and commercial development community. We firstly outline key emerging application areas for CR/geo-location. Secondly, we look how the ... -
Automated treatment of film tear in degraded archived media
(IEEE, 2004)A common form of degradation in archived film is film tear. This is caused by the physical ripping of the film. Tear causes displacement of a region of the degraded frame and the loss of image data. As of yet no method of ... -
Bandwidth-adaptive waveforms for dynamic spectrum access networks
(IEEE, 2008)This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high ... -
A Bayesian Framework for Recursive Object Removal in Movie Post-Production
(IEEE, 2003)Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires and people, for instance, can be removed by digitally ... -
Biofabrication of spatially organised tissues by directing the growth of cellular spheroids within 3D printed polymeric microchambers
(2019)Successful tissue engineering requires the generation of human scale implants that mimic the structure, composition and mechanical properties of native tissues. Here, we report a novel biofabrication strategy that enables ... -
Chemical etching of Ti-6Al-4V biomaterials fabricated by selective laser melting enhances mesenchymal stromal cell mineralization
(2024)Porous titanium scaffolds fabricated by powder bed fusion additive manufacturing techniques have been widely adopted for orthopedic and bone tissue engineering applications. Despite the many advantages of this approach, ... -
Classification and representation of semantic content in broadcast tennis videos
(IEEE, 2005)This paper investigates the semantic analysis of broadcast tennis footage. We consider the spatio-temporal behaviour of an object in the footage as being the embodiment of a semantic event. This object is tracked using ... -
Combinatorial clock auction for OFDMA-based cognitive wireless networks
(IEEE, 2008)This paper presents a novel application of a market-based spectrum assignment mechanism for exploitation by cognitive radio systems. Advances in DSA policy mean that regulators are moving towards a more liberalised ... -
A Comparative Error Analysis of Audio-Visual Source Localization
(2008)This paper examines the accuracy of audio-video based localization using multiple cameras and multi-microphones. Covariance mapping theory is used to determine the accuracy of audio and video based localization. Both ... -
A comparative study of shear stresses in collagen-GAG and calcium phosphate scaffolds in bone tissue-engineering bioreactors
(Mary Ann Liebert, 2008)The increasing demand for bone grafts combined with their limited availability and potential risks has led to much new research in bone tissue engineering. Current strategies of bone tissue engineering commonly utilize ... -
Cyclostationary signatures for rendezvous in OFDM-based dynamic spectrum access networks
(IEEE, 2007)Abstract?Distributed coordination of operating frequencies and bandwidths is one of the key challenges in the development of dynamic spectrum access (DSA) technology. The spectrum efficiency of DSA networks is achieved ... -
Cyclostationary signatures in practical cognitive radio applications
(IEEE, 2008)We define a cyclostationary signature as a feature which may be intentionally embedded in a digital communications signal, detected through cyclostationary analysis and used as a unique identifier. The purpose of this paper ... -
Deformation simulation of cells seeded on a collagen-GAG scaffold in a flow perfusion bioreactor using a sequential 3D CFD-elastostatics model.
(2009)Tissue-engineered bone shows promise in meeting the huge demand for bone grafts caused by up to 4 million bone replacement procedures per year, worldwide. State-of-the-art bone tissue engineering strategies use flow perfusion ... -
Demonstration and analyses of collaboration, co-existence, and interoperability of cognitive radio platforms
(IEEE, 2007)The Centre for Telecommunications Value-Chain Research (CTVR) and the Center for Wireless Telecommunications (CWT) are undertaking a joint collaborative research project investigating the potential of different ... -
Design and manufacture of surface acoustic wave sensors for real-time weigh-in-motion.
(IEEE, 2005)This paper presents the design and manufacture of surface acoustic wave (SAW) strain sensors which can be produced in a university environment. These sensors can be interrogated wirelessly and operated without a power ... -
Detection of Illegal Dumping from CCTV at Recycling Centres
(2007)This paper describes initial work on a framework for automatic detection of illegal dumping from CCTV footage from recycle centres. Frames are seperated into foreground and background regions using a Bayesian approach that ...
