Random walk models of worker sorting in ant colonies (2002)
Journal Article

Sorting can be an important mechanism for the transfer of information from one level of biological organization to another. Here we study the algorithm underlying worker sorting in Leptothorax ant colonies. Worker sorting is related to task allocatio...

The role of competition in task switching during colony emigration in the ant Leptothorax albipennis (2002)
Journal Article

The decision-making process that determines when an animal should switch between tasks is a fundamental issue in the study of animal behaviour. We investigated, for the first time, such task switching in terms of the dynamics of worker populations in...

Direct numerical simulation of turbulent trailing-edge flow with base flow control (2002)
Journal Article

Direct numerical simulation has been carried out for turbulent flow over a rectangular trailing edge at a Reynolds number of 1 × 103 (based on the freestream quantities and the trailing-edge thickness) and ratio of boundary-layer displacement thickne...

Text-independent speaker identification by genetic clustering radial basis function network (2001)
Presentation / Conference Contribution

The authors combine genetic clustering algorithm with radial basis function neural network (RBJFNN) for avoiding locally optimum solutions in speaker identification. The effectiveness of genetic clustering algorithm is evaluated with speech utterance... Read More about Text-independent speaker identification by genetic clustering radial basis function network.

Optimization of debris removal during bladder irrigation (2001)
Presentation / Conference Contribution

Debris build-up within the bladder is one of the main problems encountered by patients undergoing long term catheterization. One of the methods of ameliorating this is to wash out the bladder at regular intervals. In this paper, an alternative method...

In situ X-ray absorption spectroscopy and X-ray diffraction of fuel cell electrocatalysts (2001)
Journal Article

The utility of in situ X-ray absorption spectroscopy (XAS) in determining structural parameters, through analysis of the extended X-ray absorption fine structure (EXAFS), and electronic perturbations, through a white line analysis of the X-ray absorp...
