Development of a decision support system for flood forecasting and warning – a case study on the Maribyrnong River
… costly types of natural disasters in Australia and other parts of the world. It was reported that the average annual cost of flood damage in Australia was about $300 million as at 1994. However, the effects of flooding can be mitigated, and thereby reduce the loss of life and damage to property. …

Cure monitoring of composite materials using optical techniques
… remote all optical technique for the generation and detection of ultrasonics in epoxy materials has been developed at Victoria University. This requires a high power pulsed laser to induce ultrasound in the sample and an optical fibre interferometer for detection. The output of the interferometer …

Intragrating sensing using chirped optical fibre Bragg gratings
… of intragrating position (localised heat source) and strain measurement sensor systems. The design, development and performance of intensity (power) reflection spectrum based intragrating sensing systems employing chirped fibre Bragg gratings (CFBGs) are investigated. Intragrating sensing is the …

A method of characterisation of the nonlinear vibration transmissibility of cushioning materials
… products in shipment can be ascribed to shocks and vibrations experienced during transportation. Vibrations can cause resonance, which has the potential to damage the product or cause the failure of critical elements within due to the repetitive application of stresses. The response behaviour of …

Stability of bioactive isoflavones and glycolytic enzymes produced by probiotic bacteria in soy based food during processing and storage
… Bifidobacterium sp., Lactobacillus acidophilus and Lactobacillus casei were screened for β-glucosidase activity using ρ- nitrophenyl-β-D-glucopyranoside as a substrate. Six strains were selected on the basis of β- glucosidase activity produced during fermentation of soymilk. The stability of the …

An Investigation of Electro-Rheological Fluids in Engineering
… When there is no electric field, particles are randomly suspended in the base liquid. When an electric field is applied, the particles in the fluid form chains bridging the conductors of opposite polarity and turn the liquid into a solid-like gel. The process is seemingly reversible once the …
