Presentation / Conference Contribution
Brayshaw, M., & Gordon, N. (2006, July). E-commerce And E-business: A new paradigm or old business in new clothes?. Presented at IADIS International Conference e-Society, Dublin, Ireland

This paper aims to answer the question implicit in the title, namely is e-commerce and e-business a new paradigm or old business in new clothes? We consider whether this topic is truly a new discipline worthy of study and understanding in its own rig...

Polygon smoothing nurbs curves and surfaces (2005)
Presentation / Conference Contribution
Li, Q. (2005, June). Polygon smoothing nurbs curves and surfaces. Presented at Applied Simulation and Modelling (ASM 2005), Benalmádena, Spain

In conventional spline geometric shape design, each part of a designed object always evolves the same number of con trol points. This has been a disadvantage of the spline based geometric shape design schemes as much more points than necessary may be... Read More about Polygon smoothing nurbs curves and surfaces.

A recurrent neural network for sound-source motion tracking and prediction (2005)
Presentation / Conference Contribution
Murray, J. C., Erwin, H., & Wermter, S. (2004, July). A recurrent neural network for sound-source motion tracking and prediction. Presented at Proceedings of the International Joint Conference on Neural Networks, Montreal, Que., Canada

Recurrent neural networks (RNN) have been used in many applications for both pattern detection and prediction. This paper shows the use of RNN's as a speed classifier and predictor for a robotic sound source tracking system. The system requires exten...

SuperVise: Using grid tools to simplify visualization (2004)
Presentation / Conference Contribution
Osborne, J., & Wright, H. (2005, September). SuperVise: Using grid tools to simplify visualization. Presented at Parallel Processing and Applied Mathematics, 6th International Conference, PPAM 2005, Poznan, Poland

The visualization process is complicated enough for visualization experts but more so for domain specialists. Problems include managing the transfer of large datasets and choosing appropriate techniques. When we consider performing these tasks in a m...

Least squares ellipsoid specific fitting (2004)
Presentation / Conference Contribution
Li, Q., & Griffiths, J. (2004, April). Least squares ellipsoid specific fitting. Presented at Geometric Modeling and Processing, 2004., Beijing, China

In this paper, a sufficient condition for a quadric surface to be an ellipsoid has been developed and a closed-form solution for ellipsoid fitting is developed based on this constraint, which is a best fit to the given data amongst those ellipsoids w...

Implicit curve and surface design using smooth unit step functions (2004)
Presentation / Conference Contribution
Li, Q., & Phillips, R. (2004, June). Implicit curve and surface design using smooth unit step functions. Presented at ACM Symposium on Solid and Physical Modeling, Genoa, Italy

This paper presents an implicit curve and surface design technique that uses smooth unit step functions. With the proposed method, an implicit curve or surface can be generated by inputting a sequence of points together with the normals at these poin...

The current opinion on the use of robots for landmine detection (2003)
Presentation / Conference Contribution
Rajasekharan, S., & Kambhampati, C. The current opinion on the use of robots for landmine detection. Presented at 2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), Taipei, Taiwan, Taiwan

Anti-Personal landmines are a significant barrier to economic and social development in a number of countries. Several sensors have been developed but each one will probably have to find, if it exists, a specific area of applicability, determined by...

Size exclusion chromatography and rheology of AB/AB2 hyperbranched polymers (2003)
Presentation / Conference Contribution
Kunamaneni, S., Buzza, D. M. A., Parker, D., & Feast, W. J. Size exclusion chromatography and rheology of AB/AB2 hyperbranched polymers

We report size exclusion chromatography (SEC) and linear shear rheology results for a series of AB/AB2 hyperbranched polyesters. For these samples, the weight average molecular weight Mw was systematically varied from 3000 to 250000 but the spacer le...

Formulated silhouettes for sketching terrain (2003)
Presentation / Conference Contribution
Whelan, J. C., & Visvalingam, M. (2003, June). Formulated silhouettes for sketching terrain. Presented at Theory and Practice of Computer Graphics, TPCG 2003, Birmingham, UK

The mathematical definition of silhouettes within NPAR is based on the assumption that they are the eye-centered projections of occluding contours on an imaging plane. However, occluding contours are insufficient for sketching the silhouettes of hill... Read More about Formulated silhouettes for sketching terrain.

Recovery of distal hole axis in intramedullary nail trajectory planning (2002)
Presentation / Conference Contribution
Zhu, Y., Phillips, R., Griffiths, J. G., Viant, W., Mohsen, A., & Bielby, M. Recovery of distal hole axis in intramedullary nail trajectory planning

In intramedullary nail (IMN) surgical operations, one of the main efforts for surgeons is to find the axes of two distal holes. Two distal holes on an IMN, which are inside the intramedullary canal of a patient's femur, can only be seen in a lateral...

Presentation / Conference Contribution
Delgado, A., Kambhampati, C., & Warwick, K. (1996, September). Stable linearization using multilayer neural networks. Presented at UKACC International Conference on Control. Control '96, Exeter, UK

The main limitation of linearization theory that prevents its application in practical problems is the need for an exact knowledge of the plant. This requirement is eliminated and it is shown that a multilayer network can synthesise the state feedbac... Read More about Stable linearization using multilayer neural networks.

Mathematica and finite geometry (1995)
