Design of an electromechanical pump system for training in beating heart cardiac surgery (2002)
Presentation / Conference Contribution
Craven, M., Ramphal, P., Coore, D., Silvera, B., Fletcher, M., & Newman, S. (2002, April). Design of an electromechanical pump system for training in beating heart cardiac surgery. Presented at IEEE SoutheastCon 2002, Columbia, SC, USA

Heart surgeons and trainees benefit greatly from continuous practice of bypass surgery and other cardiac operations. This is true of beating heart surgery where, unlike traditional methods, the heart is not arrested during the operation. At the Dept....

The design and characterisation of an optical VLSI processor for real time centroid detection (2001)
Presentation / Conference Contribution
Boon Hean Pui, Hayes-Gill, B., Clark, M., Somekh, M., See, C., Piéri, J. F., Morgan, S., & Ng, A. (2001, April). The design and characterisation of an optical VLSI processor for real time centroid detection. Presented at Design, Test, Integration, and Packaging of MEMS/MOEMS 2001, 2001, Cannes-Mandelieu, France

The integration of photo-detectors onto a standard CMOS integrated circuit is presented. This device provides the optical front end for a real time centroid detection system to be used as part of a larger system for implementing a Shack-Hartmann wave...

Artificial loading of the induction motors using a matrix converter (2000)
Presentation / Conference Contribution
Klumpner, C., Boldea, I., & Blaabjerg, F. (2000, September). Artificial loading of the induction motors using a matrix converter. Presented at Eighth International Conference on Power Electronics and Variable Speed Drives, London, UK

The paper discuses the use of a frequency converter for artificial loading of an induction motor. The characteristic of the artificial loading requires a cyclic circulation of energy between the converter and motor in order to increase the motor curr...

Broadcasting On-Line Social Interaction as Inhabited Television (1999)
Presentation / Conference Contribution
Benford, S., Greenhalgh, C., Craven, M., Walker, G., Regan, T., Morphett, J., Wyver, J., & Bowers, J. (1999, September). Broadcasting On-Line Social Interaction as Inhabited Television. Presented at Sixth European Conference on Computer Supported Cooperative Work, Copenhagen, Denmark

Inhabited TV combines collaborative virtual environments (CVEs) with broadcast TV so that on-line audiences can participate in TV shows within shared virtual worlds. Three early experiments with inhabited TV raised fundamental questions concerning th... Read More about Broadcasting On-Line Social Interaction as Inhabited Television.

Patterns of network and user activity in an inhabited television event (1999)
Presentation / Conference Contribution
Greenhalgh, C., Benford, S., & Craven, M. (1999, December). Patterns of network and user activity in an inhabited television event. Presented at ACM Symposium on Virtual Reality Software and Technology, Proceedings, VRST, London, UK

Inhabited Television takes traditional broadcast television and combines it with multiuser virtual reality, to give new possibilities for interaction and participation in and around shows or channels. 'Out Of This World' was an experimental inhabited... Read More about Patterns of network and user activity in an inhabited television event.

A faster learning neural network classifier using selective backpropagation (1997)
Presentation / Conference Contribution
Craven, M. P. A faster learning neural network classifier using selective backpropagation. Presented at Fourth IEEE International Conference on Electronics, Circuits and Systems

The problem of saturation in neural network classification problems is discussed. The listprop algorithm is presented which reduces saturation and dramatically increases the rate of convergence.

The technique uses selective application of the bac... Read More about A faster learning neural network classifier using selective backpropagation.

Shape recognition using a novel fractal technique (1996)
Presentation / Conference Contribution
Neil, G., Curtis, K. M., & Craven, M. (1996, October). Shape recognition using a novel fractal technique. Presented at Third IEEE International Conference on Electronics, Circuits, and Systems, Rhodes, Greece

Fractal transformations are an exciting new scale invariant shape recognition technique developed by the authors. They have been successfully used for spatially invariant shape recognition using a cumbersome rotational invariance algorithm. Within th...

A combined theoretical/experimental approach to the dynamic characterization of viscoelastic materials (1992)
Journal Article
Greif, B., & Johnson, M. S. (1992). A combined theoretical/experimental approach to the dynamic characterization of viscoelastic materials. Journal of Engineering Materials and Technology, 114(1), 77-80. https://doi.org/10.1115/1.2904144

This research combines theoretical and experimental approaches to the dynamic mechanical characterization of viscoelastic materials. A detailed derivation is presented for the dynamic response of a typical viscoelastic rod sample. Particular attentio...
