Prediction of wool knitwear pilling propensity using data mining techniques

This thesis examined the application of data mining techniques to the issue of predicting pilling propensity of wool knitwear. Using real industrial data, a pilling propensity prediction tool with embedded trained support vector machines is developed to provide high accuracy prediction to wool knitwear even before the yarn is spun!

Inter-bonded fibrous matrics for 3D tissue engineering scaffolds

This thesis established a stable three-dimensional fibrous tissue scaffold that has controlled pore structure and inter-bonded fibrous structure, and also examined the effects of the 3D fibrous matrices and functional surfaces including nano-scale topography, bioactive CaP coating and antibacterial treatment on the cell growth begaviour for tissue engineering application.

Nanograin metals and metallic multilayers produced by severe plastic deformation

This research has developed an improved understanding of the structure-property relationships, fabrication technology and deformation mechanism of light bulk ultrafine grained materials and metallic multilayered structure.

Production and characterisation of nanofibre yarns and composites

This thesis propsed a novel method to produce and characterise nanofibre yarns and composites.  It contributed to the fundamental research in the field of nanofibre yarns.

Characterisation of an out-of-autoclave resin film infusion process for textile composites

A new method to manufacture damage tolerant textile composites, which combines Resin Film Infusion with a fast and cost·efficient curing technology QuickstepTM, was investigated. The effect of process parameters on resin flow through carbon fibre preforms was analysed and model-based parameter optimisation resulted in considerable improvement of resin flow properties.

Biomechanical properties of porous metal scaffolds as implant materials

The results obtained from this work reveal that high porous titanium foams have fracture mechanical properties that meet and exceed the required properties of both cortical and cancellous bones. With their good biocompatibility, light weight, strong structural integrity and possibility of bone in-growth these foams are suitable for biomedical applications.

Fatigue characterisation of HSS and AHSS

The thesis investigated the fatigue behaviour of modern automotive steels, which are stronger and more ductile than traditional steels. The failure mechanisms of these steels under fatigue were identified, enabling researchers to further improve the material properties, which will ultimately lead to a reduction in overall vehicle mass.

Bovine lactoferrin : potential antioxidant effector molecule in colon carcinoma

This research generated important insight into the antioxidant capacity and effector molecule capability of bovine lactoferrin in both its Apo- (iron free) and metal saturated forms within the gastrointestinal system, giving rise to bovine lactoferrin's potential at regulating oxidative stress associated signalling molecules within colon carcinoma.

pH-sensitive and targeted PLGA-based drug delivery to colorectal cancer

Investigation on targeted PLGA based drug delivery system for the therapy of colorectal cancer. The results from in-vitro cell experiments indicated that prepared systems have potent cytotoxicity and high affinity to HT-29 cancer cells. Results were published on Biomedical Engineering and Informatics and ICONN conference proceeding.

Modelling of bending-dominated forming processes of metal sheets

Theoretical solutions, finite element models, and experimental techniques are developed for three major sheet metal forming operations: bending (pure bending and cyclic bending), die bending, and deep drawing. These have been applied to two different commercial quality cold-rolled steels, one stainless steel, and one magnesium alloy.

Characterisation of out-of-autoclave carbon fibre composites

Out-of-autoclave processing parameters were tailored to investigate the effect of resin viscosity on mechanical performance. Faster heating rates improved the shear and fracture mechanisms of carbon fibre composites by improving their fibre to matrix adhesion, as a result of a decrease in resin viscosity.

Resolving controversies in hip fracture care : the need for large collaborative trials in hip fractures

Summary: Hip fractures are a significant cause of morbidity and mortality worldwide and the burden of disability associated with hip fractures globally vindicates the need for high-quality research to advance the care of patients with hip fractures. Historically, large, multi-centre randomized controlled trials have been rare in the orthopaedic trauma literature. Similar to other medical specialties, orthopaedic research is currently undergoing a paradigm shift from single centre initiatives to larger collaborative groups. This is evident with the establishment of several collaborative groups in Canada, in the United States, and in Europe, which has proven that multi-centre trials can be extremely successful in orthopaedic trauma research.

Despite ever increasing literature on the topic of his fractures, the optimal treatment of hip ftractures remains unknown and controversial. To resolve this controversy large multi-national collaborative randomized controlled trials are required. In 2005, the International Hip Fracture Research Collaborative was officially established following funding from the Canadian Institute of Health Research International Oppurtunity Program with the mandate of resolving controversies in hip fracture management. This manuscript will describe the need, the information, the organization, and the accomplishments to date of the International Hip Fracture Research Collaborative.
