Simulation and modelling of turbulent trailing-edge flow (2002)
Journal Article

Computations of turbulent trailing-edge flow have been carried out at a Reynolds number of 1000 (based on the free-stream quantities and the trailing-edge thickness) using an unsteady 3D Reynolds-Averaged Navier-Stokes (URANS) code, in which two-equa...

Direct Lyapunov design - A synthesis procedure for motor schema using a second-order Lyapunov stability theorem (2002)
Presentation / Conference Contribution

In this paper we propose a new procedure for construction of motor schema typically used in behaviour-based robotics. The procedure reverses the standard stability analysis approach by searching for a
control function to fit a pre-defined Lyapunov f... Read More about Direct Lyapunov design - A synthesis procedure for motor schema using a second-order Lyapunov stability theorem.

Development of a one point quadrature shell element for nonlinear applications with contact and anisotropy (2002)
Journal Article

A general purpose shell element for nonlinear applications including sheet metal forming simulation is developed based on reduced integration with one point quadrature. The developed shell element has five degrees of freedom and four nodes. It covers...

Concentrations of Cd, Zn and Cu in sediments and brown shrimp (Crangon crangon L.) from the Severn Estuary and Bristol Channel, UK (2002)
Presentation / Conference Contribution

Cd, Zn and Cu levels were determined in sediments and Crangon crangon from 9 sites in the Severn Estuary/Bristol Channel during winter 1999. Metal levels in both shrimp and sediments varied significantly between sites and were related to proximity of...

Neural networks for improved text-independent speaker identification (2002)
Journal Article

In this article, we consider the binary partitioned approach with pattern index information, propose an neural network array (NNA) that performs the pattern recognition task by combining the binary partitioned approach with decision trees, and verify...

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...
