Aims—A prospective, randomised, double blind study was used to investigate the eVect of hyaluronidase on the quality of block achieved with sub-Tenon’s local anaesthesia. Methods—150 patients scheduled for elective cataract surgery were randomly allocated to either sub-Tenon’s block with 3 ml lignocaine 2%/adrenaline 1:200 000 alone or with the addition of 30 IU/ml of hyaluronidase. The blocks ...

Graphs are very powerful and widely used representational tools in computer applications. In this paper, we present a relaxation approach to (sub)graph matching based on a fuzzy assignment matrix. The algorithm has a computational complexity of ( 2 ) where and are the number of nodes in the two graphs being matched, and can perform both exact and inexact matching. To illustrate the performance ...
