The impact of cultural aspects on the design process (2004)
Presentation / Conference Contribution
Felgen, L., Grieb, J., Lindemann, U., Pulm, U., Chakrabati, A., & Vijaykumar, G. (2004, May). The impact of cultural aspects on the design process. Presented at DESIGN 2004, the 8th International Design Conference, Dubrovnick, Croatia

Due to increasing globalisation, the development of products is no longer restricted to one place, it is more and more characterised by distributed design teams, who work in different places, time zones or cultures. In order to support intercultural... Read More about The impact of cultural aspects on the design process.

Sliding mode position control of a vector-controlled induction machine with nonlinear load dynamics (2004)
Presentation / Conference Contribution
Goh, K., Dunnigan, M., & Williams, B. (2004, March). Sliding mode position control of a vector-controlled induction machine with nonlinear load dynamics. Presented at Second IEE International Conference on Power Electronics, Machines and Drives, Edinburgh, United Kingdom

In this paper, a solution to the position control problem for a vector controlled induction machine in the presence of nonlinear load friction, is proposed. A sliding mode (SMC) control system using the equivalent control concept and a switching term...

Cavitation Properties of Oils Under Dynamic Stressing by Tension (2004)
Journal Article
Williams, P. R., & Williams, R. L. (2004). Cavitation Properties of Oils Under Dynamic Stressing by Tension. Journal of Fluids Engineering, 127(2), 282. https://doi.org/10.1115/1.1881692

We report measurements of the effective tensile strength FcFc of commercial “multigrade” oils (in the SAE viscosity grades 5W-30 and 10W-40) over a range of temperatures TT, which are representative of those encountered under their normal operating c...

Cavitation and the tensile strength of liquids under dynamic stressing (2004)
Journal Article
Williams, P. R., & Williams, R. L. (2004). Cavitation and the tensile strength of liquids under dynamic stressing. Molecular Physics, 102(19-20), 2091-2102. https://doi.org/10.1080/00268970412331292786

This paper discusses the differences between the results of various measurements of the effective tensile strength (F c ) of liquids in experiments involving a pulse of tension (‘negative pressure’) created by the reflection of a pressure pulse at a...

Phase relations for decomposable soils (2004)
Journal Article
McDougall, J. R., & Pyrah, I. C. (2004). Phase relations for decomposable soils. Géotechnique, 54(7), 487-493. https://doi.org/10.1680/geot.54.7.487.46750

Expressions describing the phase composition and interphase relations for a decomposable soil are derived by distinguishing between inert and decomposable fractions. A relationship between void volume changes and decomposition of the solid fraction,... Read More about Phase relations for decomposable soils.

Rheology of Dilute Polymer Solutions and Engine Lubricants in High Deformation Rate Extensional Flows Produced by Bubble Collapse (2004)
Journal Article
Barrow, M. S., Brown, S. W. J., Cordy, S., Williams, P. R., & Williams, R. L. (2004). Rheology of Dilute Polymer Solutions and Engine Lubricants in High Deformation Rate Extensional Flows Produced by Bubble Collapse. Journal of Fluids Engineering, 126(2), 162. https://doi.org/10.1115/1.1667889

We report a study of liquid jets formed by the collapse of bubbles under cavitationgenerated pressure waves. Such jets involve an extensional flow which is characterized by high rates of extension, the latter being relevant to considerations of the f...

Constraint neuro-model based predictive control (2004)
Presentation / Conference Contribution
Soufian, M., Rahman, A. A., Soufian, M., & Mokbe, A. A. (2002, December). Constraint neuro-model based predictive control. Presented at 4th International Conference on Recent Advances in Soft Computing, Nottingham, England

Constraints are always present in the real life process. Control of processes without considering the constraints can lead to sub-optimal behaviour and may result in instability and violation of safety. Lack of a solid and applicable closed loop cont...

The application of sliding mode control algorithms to a deisel generator set (2004)
Book Chapter
Goh, K., Spurgeon, S., & Jones, B. (2004). The application of sliding mode control algorithms to a deisel generator set. In Variable structure systems : from principles to implementation. Institution of Engineering and Technology (IET). https://doi.org/10.1049/PBCE066E_ch

This chapter demonstrates the application of both standard, first order sliding mode control and higher order sliding mode control techniques to a specific diesel power generator. The specific first order methods considered are sliding mode integral... Read More about The application of sliding mode control algorithms to a deisel generator set.
