Fibre Microstructure and Mechanics of Atherosclerotic Plaques
… and rupture risk of atherosclerotic plaques. Fibre structures in human atherosclerotic plaques were characterised through scanning electron microscopy, histology, and image processing. Local primary fibre orientation and the fibre dispersion were calculated. Plaque shoulder regions, where …

Dispersion aspects of periodically amplified soliton transmission systems
… to the main concepts and impairments of optical fibre on pulse transmission is included before introducing the concept of solitons in optically amplified communications and the problems of soliton system design. The theoretical work studies two fibre dispersion profiling schemes and a soliton …

Effect of microstructure on mechanical behaviour of arterial tissue
… (GAG) contents, as well as collagen fibre dispersion on the mechanical and fracture behaviours. Both collagen and GAGs were associated with tissue strength, while higher GAG deposition was found to result in larger local collagen fibre dispersion in media and adventitia layers, but …

The application of SOA for dispersion management of 2D-WH/TS codesin incoherent OCDMA system
In high data rate optical fibre communication networks, dispersion phenomenon plays a pivotal role. It is important to investigate the dispersion effects in a multi-wavelength picosecond optical code division multiple access (OCDMA) system. This research is focused on the analysis of the effects of …

Residual stress determination in advanced silicon carbide fibre reinforced aluminium matrix composites
… those that are reinforced by long continuous fibres (such as carbon, alumina, silicon, boron and carbide) or those reinforced by discontinuous fibres (particulates). The addition of fibres and particulates reinforcements enhance desirable properties of the base metal (matrix). A key benefit of …

The Improvement of Interfacial Bonding, Weathering and Recycling of Wood Fibre Reinforced Polypropylene Composites
This study deals with medium density wood fibre (MDF) and Kraft fibre reinforced polypropylene (PP) composites produced using extrusion followed by injection moulding. Initially, composites were produced with MDF fibre using 10, 20, 30, 40, 50 and 60 wt% fibre, and 1, 2, 3 and 4 wt% maleated …

Self-healing strain-hardening cementitious composites (SH2CC) for cyclic loading environments
… techniques could be applied in combination with fibre-reinforced strain-hardening cementitious composites (SHCC); the former enables cementitious materials to heal cracks without human intervention, and the latter features much higher ductility than traditional concrete due to effective fibre …
