Approximate closed-form solutions are developed for estimating the frequency separation caused by thickness, density, or radius azimuth variations in ring or hemispherical gyroscopes. For the nth flexural mode, frequency separation is caused by the 2n harmonic of density or thickness variation. These relations are combined with stochastic models to determine approximate closed-form solutions relating...
Craniofacial researchers make heavy use of established facial landmarks in their morphometric analyses. For studies on very large facial image datasets, the standard approach of manual landmarking is very labor intensive. With the goal of producing 20 established landmarks, we have developed a geometric methodology that can automatically locate 10 established landmark points and 7 other supporting...
Morphometrics, the quantitative analysis of shape, is used by craniofacial researchers to study abnormalities in human face shapes. Most of the work in craniofacial morphometrics uses landmark points that are manually marked on 3D face data and processed via a generalized Procrustes analysis. For large data sets this manual process is very time-consuming. Dense sets of pseudo-landmarks have also been...
In this paper, we review the current understanding of energy loss mechanisms in micromachined (MEMS and NEMS) devices. We describe the importance of high quality factor (Q) to the performance of MEMS gyros and MEMS resonators used in radio-frequency applications.
Formal technical reviews supply the quality measurement to the ``cost effectiveness'' equation in a project management system. There are several unique formal technical review procedures, each applicable to particular types of technical material and to the particular mix of the Review Committee. All formal technical reviews produce reports on the overall quality for project management, and specific...
