This paper concerns the inverse problem of localising an impulsive acoustic source in an urban environment using measurements from multiple receivers (microphones) distributed through the propagation domain. In free space the inverse problem is readily solved by Time Difference Of Arrival (TDOA) localisation. In urban environments there may not be a lineof-sight (LOS) between the source and eac...

A 29 year old myopic man sustained two separate giant retinal tears in his right eye following deliberate eye gouging during a rugby tackle. These were successfully repaired by vitrectomy and intraocular silicone oil injection. Although the postoperative course was complicated by pupil block glaucoma, he regained corrected visual acuity of 6/5 after oil removal. This injury highlights the poten...

Retinal prostheses are a promising means for restoring sight to patients blinded by the gradual atrophy of photoreceptors due to retinal degeneration. They are designed to reintroduce information into the visual system by electrically stimulating surviving neurons in the retina. This review outlines the concepts and technologies behind two major approaches to retinal prosthetics: epiretinal and...

UNLABELLED Settings and Aim: The World Health Organization launched in 1999 an initiative to eliminate the global avoidable blindness and prevent the projected doubling of avoidable visual impairment between 1990 and 2020 (Vision 2020: The Right to Sight). The World Health Assembly (WHA) adopted resolutions WHA 59.25, WHA 56.26 urging member states to adopt the Vision 2020 principles. More than...

This paper develops a theoretical model to help answer the following question— what influences an individual’s opinions regarding the right to privacy of others (individuals, organizations, and governments)? This question is particularly relevant for organizations and governments, for whom insider threats to corporate or government privacy present a dangerous risk. We draw from three bases of l...

But despite the portrait and interrogation by doctors in London, Jesty never received credit for his pioneering work, with all the credit and financial rewards going to Jenner with his many friends in the medical establishment in London who spent considerable time and money refining the technique. Jenner never accepted that he had been preempted over vaccination by Jesty. However, the Jestys fr...

This piece examines situations in which judges are called upon to develop and modify the common law. By reference to a number of recent developments in the United Kingdom and Australia, namely the law of evidence and common law privilege, the right to privacy, and causation in the tort of negligence, the author elucidates the manner and extent to which judges have and are able to develop the la...
