We calculated how long to wait before repeating bone mineral density (BMD) measurements to reassess fracture risk. Correlation results from serial measurements of 495 postmenopausal Japanese-American women were used to estimate 95% confidence intervals (CI) for future BMD. After 7 years of follow-up, BMD correlations with the initial measurement ranged(More)
In this paper, we examine the control of a scramjet-powered hypersonic vehicle with significant aeroelastic-propulsion interactions. Such vehicles are characterized by open loop unstable non-minimum phase dynamics, low frequency aero-elastic modes, significant coupling, and hard constraints (e.g. control surface deflection limits, thrust margin). Within(More)
This paper presents a novel methodology for a control of aircraft using spatially distributed surface pressure sensors namely, flush air data sensors (FADS). The methodology combines the advantages derived from robustness properties of passivity-based control theory with richness of sensory information obtained from judiciously distributed network of highly(More)

Scramjet powered hypersonic vehicles represent the next critical step toward achieving NASA’s vision for Highly Reliable Reusable Launch Systems (HRRLS), affordable space access, planetary re-entry systems, and global reach vehicles. The design of such vehicles is a very interdisciplinary and highly complex problem. As such, the development of varying(More)
