BACKGROUND Symmetry is one of the criteria of achieving a good aesthetic result. Realising this can be difficult. Attempts have been made to try and measure this symmetry using advanced and complex methods.1 For most surgeons on a daily basis the only practical way to measure symmetry is to use a simple measuring tool such as a measuring tape. However, this method is not very reliable as it dep...

This paper studies the classification of recursive sets by the number of tape reversals required for their recognition on a two-tape Turing machine with a one-way input tape. This measure yields a rich hierarchy of tape-reversal limited complexity classes and their properties and ordering are investigated. The most striking difference between this and the previously studied complexity measures ...

A tape measure, based on 50th centile weight for height and designed to permit easy drug dosage calculation, endotracheal tube size and DC cardioversion current dosages in childrens' emergencies, was tested for reliability by medical and nursing staff with varying paediatric experience. We found that the tape measure gave a reproducible estimate of weight and suggest that its use would facilita...

Theoretical predictions were made for the dynamic performance of a tangential flux magnetic thrust bearing. A prototype bearing was built with the stators and rotors made from tape wound strip. The performance of this bearing was measured and compared to the theoretical predictions and also to the performance of a radial flux thrust bearing. Tangential flux bearings are intrinsically amenable t...

This paper reports results of the test of HTS conductor manufactured by Intermagnetics General Corporation (IGC). The HTS version of the CESR dual bore quadrupole magnet has been analyzed using data obtained in this test. 1 HTS test The main purpose of the experiments described below was to obtain HTS characteristics needed for magnet design. The prime goal was to measure the HTS performance de...
