Many patients suitable for a lip augmentation are of face lift age, and could benefit from a simultaneous lip enhancement during the rhytidectomy procedure. The healthy, live superficial musculoaponeurotic system (SMAS) tissue obtained from the face lift can be recycled and grafted with minimal additional operating time. From April of 1995 to January of 2000, 103 patients (99 women and four men...

We describe a roundness classiication procedure , that is, a procedure to determine if the roundness of a planar object I is within some 0 from an ideal circle. The procedure consists of a probing strategy and an evaluation algorithm working in a feedback loop. This approach of combining probing with evaluation is new in computational metrology. For several deenitions of roundness, our procedur...

A number of subjective and objective methods have been proposed, and are in use, to determine the roundness of sedimentary rock particles. Roundness, which is one of three properties describing the shape of a particle, is a measure of the extent to which the corners and edges of a particle have been worn away. The objective roundness measures are mainly based on the Fourier transform. In this p...

Reynolds number and cowl position effects on the internal shock structure and the resulting performance of a generic three-dimensional sidewall compression scramjet inlet with a leading edge sweep of 45 degrees at Mach 10 have been examined both computationally and experimentally. Prior to the experiment, a threedimensional Navier-Stokes code was adapted to perform preliminary parametric studie...

SUMMARY An experiment designed to measure the external drag of fuselage side intakes is described. The scope of the experiment and the techniques employed are discussed and an assessment is made of the accuracy of results. Measurements of the external drag of rectangular intakes installed on the sides of a fuselage are presented. Results at subsonic speeds show that drag at full flow is indepen...

The objective of this work is to reshape a nacelle to achieve a specified nacelle pressure distribution. The nacelle may be either isolated or installed on an airplane. There are no restrictions on the attitude (toe, incidence, and roll) and position of the nacelle. The design algorithm is coupled to two different multi-block 3-D Navier Stokes flow solvers. The coupling between design and analy...

A new concept referred to as the batch roundness is presented in this paper. This concept is derived to illustrate the worst possible form error for a batch of circular features machined under the same conditions. It is to be used as a statistical quality measure for such a batch of circular features and evaluated by analyzing their systematic and random form error components. The definition of...

Talyrond-TR is a modern sensitive instrument in nanometrology. The performance of Talyrond-TR machine is very important to find an optimal result in roundness measurement. In this paper, the experimental evaluation method of Talyrond-TR 73 machine is designed by using reference standard hemisphere. The influence of Talyrond machine performance in roundness measurement is presented. Signal respo...

In this paper, we propose a new roundness parameter R, to denote circularity corrected by aspect ratio. The basic concept of this new roundness parameter is given by the following equation: R = Circularity + (Circularity perfect circle Circularity aspect ratio) where Circularityperfect circle is the maximum value of circularity and Circularityaspect ratio is the circularity when only the aspect...
