An Investigation into the uncanny: character design, behaviour and context.
… key components, the aesthetic, the behaviour and the contextualisation. Attempts were made to develop a greater understanding of how these components contribute to the appeal of a character within the field of 3D computer animation. Research consisted of two experiments. Both experiments were …

Automatic tailoring and cloth modelling for animation characters.
… the production of blockbuster films, TV series and computer games. The outfit of character plays an important role in the application of virtual characters. It is one of the key elements reflects the personality of character. Virtual clothing refers to the process that constructs outfits for …

Data mining and database systems: integrating conceptual clustering with a relational database management system.
Many clustering algorithms have been developed and improved over the years to cater for large scale data clustering. However, much of this work has been in developing numeric based algorithms that use efficient summarisations to scale to large data sets. There is a growing need for scalable …

Building well-performing classifier ensembles: model and decision level combination.
… performance from classification systems, and prediction systems in general. Ensemble methods, or the combining of multiple classifiers, have become an accepted and successful tool for doing this, though the reasons for success are not always entirely understood. In this thesis, we review …

Critical computer animation: an examination of "practice as research" and its reflection and review processes.
… the “Practice as Research” model for critical 3D computer animation. I designed a structure for the model using mixed research methods and a critical process, and applied this proposed methodology first into a pilot study to examine some selected methods and identify other required techniques for …

3D digital relief generation.
… of shapes carved on a surface so as to stand out from the surrounding background. Traditional relief creation is done by hand and is therefore a laborious process. In addition, hand-made reliefs are hard to modify. Contrasted with this, digital relief can offer more flexibility as well as …

Hybrid modelling of time-variant heterogeneous objects.
… of a number of advanced theoretical concepts and practical techniques for describing such physical objects. As a result, the process of modelling and animating certain types of homogeneous objects became feasible. In fact most physical objects are not homogeneous but heterogeneous in their …

Embedding requirements within the model driven architecture.
… transformations between software design models, and the automatic generation of application code from those models. Software systems are provided by developers, whose experience and models are not always in line with those of other stakeholders, which presents a challenge for the community. From …

Enabling collaborative modelling for a multi-site model-driven software development approach for electronic control units.
… which appear to better depict their understanding of certain model elements presented in a diagram. That is, that the layout of the model brings meaning which exceed the simple structural or topological connections. However, tools for merging such models tend to do so from a purely …

Adaptive motion synthesis and motor invariant theory.
… are tedious to use, computationally expensive and fail to capture natural looking features. These difficulties seem to suggest that artificial control techniques are inferior to their natural counterparts. Recent advances in biology research point to a new motor control principle: utilizing the …

Constrained parameterization with applications to graphics and image processing.
… parametric domain. It has been widely applied to computer graphics and image processing fields. The challenging issue is that the usual positional constraints always result in triangle flipping in parameterizations (also called foldovers). Additionally, distortion is inevitable in …

Sketch-based skeleton-driven 2D animation and motion capture.
… 2D animation production, 2D motion capture and a cartoon animation filter. For 2D animation production, the traditional way is drawing the key-frames by experienced animators manually. It is a laborious and time-consuming process. With the proposed techniques, the user only inputs one image …

An investigation into the implementation issues and challenges of service oriented architecture
… on XML technology was developed; first to understand the technology behind web services and secondly to demonstrate the limitations of the original SOA framework especially in the area of automatic service discovery and automatic service composition. To further investigate how the Semantic layer …

Combinations of time series forecasts: when and why are they beneficial?.
… have shifted towards gaining a deeper understanding of the reasons a forecasting method may perform well in some conditions whilst it may fail in others. This thesis provides a number of contributions to this matter. Traditional empirical evaluations are discussed from a novel point of view, …

Machine learning for network based intrusion detection: an investigation into discrepancies in findings with the KDD cup '99 data set and multi-objective evolution of neural network classifier ensembles from imbalanced data.
… has undergone some criticism in the literature, and it is out of date. Therefore, some researchers question the validity of the findings reported based on this data set. Furthermore, as identified in this thesis, there are also discrepancies in the findings reported in the literature. In some …

Automatic skeletonization and skin attachment for realistic character animation.
… are concerned with two of them: skeletonization and weight assignment for skin deformation. The fonner is to generate a skeleton, which is placed within the character model and links the motion data to the skin shape of the character. The latter assists the modelling of realistic skin shape when …

The Derivation of a pragmatic requirements framework for web development.
… applications to many different types of end user and stakeholders. Web Engineering as a research area, was created to introduce processes that enable web based development to be repeatable and to avoid potential failure in the fast changing landscape that is the current ubiquitous Internet. A …

Physically inspired methods and development of data-driven predictive systems.
… models is perceived as a combination of both science and art. Although the designer of a predictive system effectively follows a prescribed procedure, his domain knowledge as well as expertise and intuition in the field of machine learning are often irreplaceable. However, in many practical …

Meta-data to enhance case-based prediction.
… used in Case-Based Prediction (CBP) systems and the reliability of their constituent cases prior to the system's deployment to influence user confidence on the delivered solutions. The reliability information, referred to as meta-data, is then used to enhance prediction accuracy. CBP is a …
