With industrial development, industrial products have become more refined and complex, resulting in increased necessity for manufacturers to come up with a robust method of measurement to check whether or not the products have been produced correctly to meet customers’ needs. As a result, significant attention has been drawn to industrial photogrammetry to satisfy such needs without contacting ...

OBJECTIVE To test whether standard information for patients using Crunchie and Aero chocolate bars to explain bone health and risk of fracture is robust. DESIGN Observational study. SETTING Domestic kitchen in rural west Wales. PARTICIPANTS 10 Crunchie bars and 10 Aero bars. MAIN OUTCOME MEASURE Fracture after falls from varying heights. RESULTS Both Crunchie and Aero bars exhibited t...

A new integrated aero-structural design method for aerospace vehicles is presented. The approach combines an aero-structural analysis solver, a coupled aero-structural adjoint solver, a geometry engine, and an efficient gradient-based optimization algorithm. The aero-structural solver ensures accurate solutions by using high-fidelity models for the aerodynamics, structures, and coupling procedu...

Results of experimental measurements of aero-optical distortions caused by turbulent boundary layers at subsonic speeds M = 0.4...0.6 are presented. Measurements were performed using a high-speed Shack-Hartmann sensor and a Malley probe to collect instantaneous wavefronts with high spatial and temporal resolution. Effects of different aperture sizes on levels of aero-optical aberrations and cor...

This paper presents an adjoint method for sensitivity analysis that is used in an aero-structural aircraft design framework. The aero-structural analysis uses high-fidelity models of both the aerodynamics and the structures. Aero-structural sensitivities are computed using a coupled-adjoint approach that is based on previously developed single discipline sensitivity analysis. Alternative strate...

The Center/TRACON Automaton System (CTAS) is a set of air traffic management tools developed by NASA in conjunction with the FAA. As part of its functionality, CTAS predicts aircraft flight trajectories using aeropropulsive models and the kinetic equations of motion for various flight conditions including climbs. Precise aeropropulsive models for all aircraft types are not yet available to NASA...

In this paper recent in-flight aero-optical measurements on the Airborne Aero-Optics Laboratory (AAOL) will be given. Instrumentation and experimental set-up will be presented. Results of an extensive survey of the aero-optical environment at different viewing angles for both flat-window and conformal-window turrets at different subsonic and low transonic speeds, below M = 0.65, will be present...

Aero-allergens in South Africa that are also encountered around the world are listed in Table I. In addition to this wide range of common aero-allergens, South Africans are also exposed to a full range of food allergens, some of which, e.g. perlemoen (Haliotis midae) and other seafood allergens, are unique to this region. Some may also be encountered during food processing. This review focuses ...
