Landmark Identification

The Reflex Microscope has become a standard instrument for the precision measurement of orthodontic record models. In this study, 31 individuals with no previous experience of the microscope were assessed for their precision at identifying well defined landmarks. Considerable initial variation existed in the precision of landmark identification, but despite only a limited training period, some of the novices tested achieved a high standard of precision. Mean errors were greatest in the z axis, i.e. along the axis of the eye, and astigmatism was common amongst those recording the greatest errors in this axis. A group of individuals who performed poorly initially, were retested after additional training and practice with the microscope. Method errors were significantly reduced for the majority of those retested, but the test apparatus identified two individuals for whom further measurement with the microscope would be inadvisable.

Selection Of

The optimal selection of the standard instrument departure procedure design (SIDPD) scheme is directly related to flight safety, air traffic flow management, and efficient use of airspace of aerodrome. In practice, the selection of the SIDPDs scheme is usually based on experts knowledge and experience in order to determine the optimal solution, which has the subjectivity and arbitrariness defects. In this paper, we comprehensively study the influence factors of standard instrument departure procedure design (SIDPD) scheme and establish an optimal evaluation index system. In addition, through applying relative membership degree rule, we build an evaluation model for optimization of SIDPD based on the evaluation of each index in the form of interval number. At the end of this paper, we show the effectiveness and feasibility of this model through an example.
