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...

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...

High resolution measurement and modelling of magnetic domain structures in epitaxial FePd (001) L10 films with perpendicular magnetization (2001)
Journal Article

Magnetic domain structures in two 50 nm thick chemically-ordered FePd (001) epitaxial films with different perpendicular anisotropies have been studied using Lorentz microscopy. Domain and domain wall structures vary significantly according to the ma...

Efficacy of clinical hypnosis in the enhancement of quality of life of terminally ill cancer patients (2001)
Journal Article

The fact that terminal cancer patients experience considerable psychological distress is now undisputed, but the effectiveness of psychological treatments in relieving this suffering is less clear. The aim of the present research was to evaluate the... Read More about Efficacy of clinical hypnosis in the enhancement of quality of life of terminally ill cancer patients.

A quadrilateral mesh generator for adaptive procedures in bulk forming processes (2000)
Journal Article

Instability of equilibria in some delay reaction-diffusion systems (2000)
Journal Article

A new result is derived which extends a known instability result for a class of reaction-diffusion equations to a corresponding system incorporating time delay effects. For a significant class of nonlinear equations it is shown that an unstable equil... Read More about Instability of equilibria in some delay reaction-diffusion systems.

Designs for accumulation analysis and related methods (2000)
Journal Article

New designs for ordered categorical data are presented which allow a valid application of chi-square type techniques in the multifactorial two level experimental situation.

Colonoscopy aided by magnetic 3D imaging: Assessing the routine use of a stiffening sigmoid overtube to speed up the procedure (1999)
Journal Article

There are not enough trained colonoscopists to cope with the present recommended number of examinations required for diagnostic and surveillance purposes. If colorectal cancer screening is to be introduced, endoscopic examination of the large bowel n...

Colonoscopy aided by magnetic 3D imaging: Is the technique sufficiently sensitive to detect differences between men and women? (1999)
Journal Article

Colonoscopy tends to be more difficult to perform in women. Women also experience more pain during flexible sigmoidoscopy, and the mean insertion distance of the instrument is less than in men. The `Bladen system', first described in 1993, is a non-r...

Do the right thing: When clients aren't clear about what they want (1998)
Journal Article

A heuristic method for lot-sizing in multi-stage systems (1997)
Journal Article

This article considers the lot-sizing problem in multi-stage production settings with capacity-constrained resources. This problem deals with the determination of a production plan for the end item and its components in order to meet the forecast dem...

Modeling crowd dynamics through coarse-grained data analysis
Journal Article

Understanding and predicting the collective behaviour of crowds is essential to improve the efficiency of pedestrian flows in urban areas and minimize the risks of accidents at mass events. We advocate for the development of crowd tra... Read More about Modeling crowd dynamics through coarse-grained data analysis.

Electrifying bacteria: The power of pee

An introduction into the wonderful world of microbial fuel cells and pee powered toilets.

An inverse normal transformation solution for the comparison of two samples that contain both paired observations and independent observations
Journal Article

Inverse normal transformations applied to the partially overlapping samples t-tests by Derrick et.al. (2017) are considered for their Type I error robustness and power. The inverse normal transformation solutions proposed in this paper are shown to m...
