Disc defect classification for optical disc drives
IEEE Transactions on Consumer Electronics, 2005Optical disc drives are subject to various disturbances and faults. A special type of fault is the so-called disc defect. In this paper we present an approach for disc defect classification. It is based on hierarchical clustering of measured signals that are affected by disc defects. The timeseriesare mapped into a feature space after which the feature

Cervical disc arthroplasty for less-mobile discs
Journal of Neurosurgery: Spine, 2019OBJECTIVEThe published clinical trials of cervical disc arthroplasty (CDA) have unanimously demonstrated the success of preservation of motion (average 7°–9°) at the index level for up to 10 years postoperatively. The inclusion criteria in these trials usually required patients to have evident mobility at the level to be treated (≥ 2° on lateral ...

Active discs for automated optic disc segmentation
2015 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2015Glaucoma is currently one of the major causes of vision loss worldwide. Though the lost vision capability cannot be recovered, preventive steps such as clinical diagnosis and necessary treatment can be taken in order to minimize visual impairment due to glaucoma. The process of clinical diagnosis needs manual examination and outlining of the optic disc

Disc-full of drugs: compressed ophthalmic discs
British Journal of Ophthalmology, 2010Cover illustration courtesy of Mr Richard Keeler, curator of the museum of the Royal College of Ophthalmologists, UK. Cover photo: Mark Thomas. Drug delivery to the eye has always been a matter of interest and innovation. One such endeavour is illustrated on the front cover, which shows a set of 24 circular boxes made in bone, with each box ...

Disc-to-Macula Distance to Disc-Diameter Ratio for Optic Disc Size Estimation
Journal of Glaucoma, 2002To investigate the usefulness of the parameter of disc-to-macula distance (DM) to disc-diameter (DD) ratio in estimating optic disc size.A total of 88 normal subjects, 18 subjects with physiological macrodiscs, and 16 early glaucomatous patients were recruited for the study.
