This paper reviews the range of sensors used in electronic nose (e-nose) systems to date. It outlines the operating principles and fabrication methods of each sensor type as well as the applications in which the different sensors have been utilised. It also outlines the advantages and disadvantages of each sensor for application in a cost-effective(More)
We assessed the long-term safety and efficacy of finasteride, an orally active 5 alpha-reductase inhibitor, in 2 previously reported groups of patients with symptomatic benign prostatic hyperplasia (BPH). Prostate volume was measured by magnetic resonance imaging, and the maximum urinary flow rate was assessed noninvasively. Symptoms were scored utilizing a(More)
Magnetic Resonance Imaging (MRI) has been used to measure the shape of the vocal tract during speech in several recent studies. Its safety to the subject, high quality imaging of soft tissue, and the ability to select relatively thin imaging planes at any angle are significant advantages over other imaging methods used for speech research. The most(More)
Detailed in this work is the design and development of a handheld electronic nose nose with an array of conducting polymer composite film sensors interfaced to a Compaq iPAQ. The device has potential applications in homeland security, such as screening people packages, luggage and vehicles at key locations such as airports or government buildings, for the(More)
Detection of bacteria such as <i>Ralstonia pickettii</i> in high purity water (HPW) has gained increasing interest for researchers. Contamination problems in HPW in both pharmaceutical and semiconductor applications can lead to a reduction in performance and inefficiency in production chains leading to huge expense. Real time detection of these bacteria in(More)
This paper describes the effect of hypermer PS3 surfactant on the response of PEA \ CB sensors to 20000 ppm of propanol. The surfactant was varied from 10-50 mg and its effect on the response and properties of the sensor material were examined. It was found that increasing the amount of surfactant in the sensors significantly improved batch-to-batch(More)
Multi-parametric MR image registration combines different imaging sequences to enhance visualisation and analysis. However, alignment of the different acquisitions is challenging, due to contrast-dependent anatomical information and abundant artefacts. For two decades, voxel-based registration has been dominated by methods based on mutual information,(More)
