The most common presentation of nonsyndromic craniosynostosis is that of the sagittal suture. Amongst this subgroup there is a significant male preponderance. Although the etiology is largely unknown, androgen exposure in utero has been suggested as

This paper looks at the implementation of a Sliding Mode Observer (SMO) based Reconfiguration algorithm to deal with sensor faults within the context of navigation controllers for Autonomous Underwater Vehicle (AUV). In this paper the reconfigurabili

Artificial neural networks and genetic algorithms are often quoted in discussions about the contribution of biological systems thinking to engineering design. This paper reviews work on the neuromuscular system, a field in which biological systems th

The optimisation of the PID controllers' gains for separate propulsion and heading control systems of CyberShip I, a scale model of an oil platform supply ship, using Genetic Algorithms is considered. During the initial design process both PID contro

Questions of the quality of computer-based models and the formal processes of model testing, involving internal verification and external validation, are usually given only passing attention in engineering reports and in technical publications. Howev

The optimization of nonlinear controller parameters by Genetic Algorithm (GA) is explored in this paper. The type of nonlinear controller that is considered is derived from sliding mode control theory, which is known for its robust properties. The GA

Model validation is an important but often neglected aspect of the engineering design process. In the control systems field the accuracy of mathematical models which represent the dynamics of the system being controlled can be of critical importance

Sagittal synostosis (SS) is the commonest form of craniosynostosis. Children with sagittal synostosis in Ireland are treated in the National Paediatric Craniofacial Centre (NPCC) in Temple Street Children's University Hospital. This retrospective stu
