This study presents a novel application of mesh-free method using the smoothed-radial basis functions for the computational homogenization analysis of materials. The displacement field corresponding to the scattered nodes within the representative volume element (RVE) is split into two parts including mean term and fluctuation term, and then the fluctuation one is approximated using the integrated radial basis function (iRBF) method.

In this paper, a computational approach using a combination of the upper bound theorem and the bubbleenhanced quadrilateral finite element (FEM-Qi6) is proposed to evaluate bearing capacity factors of strip footing in cohesive-frictional soil. The new element is built based on the quadrilateral element (Q4) by adding a pair of internal nodes to solve the volumetric locking phenomenon.

Classical ways of determination of influence lines for structural responses are often inefficient due to high computational cost, especially if properties of the structure are uncertain. The combination of Muller-Breslau principle and the finite element analysis can resolve this problem. In this study, formulations for new finite elements tailored for use in determination of influence lines for structural responses are proposed.

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.

This research project explores the effectiveness of an auditory display prototype for the sonification of internet \(c{o_2}\) emissions to a small user group within their office context. To date, methods do not exist for the reporting of this information to users of personal computing while they perform simple internet enquiries. Underpinning the theoretical development of this project is a focus on auditory displays guided by the concept and forms of auditory displays, together with the auditory perception elements to be considered in their design.

3D animation software is extensively used to create graphics for special effects sequences in live-action films, in animated feature film production and for the generation of computer games and virtual reality content. It is a commonly held view within the computer graphics community that 3D animation software is ―just another tool‖ for self-expression. This research questions that view by examining the inherent nature of the tool itself. In doing so, some of the philosophical assumptions embedded in the design of the new digital tool are revealed.

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.
