The Multidisciplinary Design Optimization of a Distributed Propulsion Blended-Wing-Body Aircraft
… elevons with a vectored thrust system for longitudinal control. An extension of Spence's Jet Flap theory was developed to estimate the effects of this vectored thrust system on the aircraft longitudinal control. It was found to provide a reasonable estimate of the control capability of the …

Do In-Vehicle Systems Utilizing Voice-Recognition Technology Impact Driving Performance? A Systematic Review and Meta-Analysis
… measures of detection, reaction time, lateral control and longitudinal control were conducted with 43 studies meeting inclusion criteria. Some driving performance benefits were observed relative to visual-manual systems, but there were also considerable impairments relative to baseline driving. …

Stratification on the Skagit Bay tidal flats
Estuarine density stratification may be controlled primarily by cross-shore processes (analogous to longitudinal control in narrow estuaries), or by both cross- and alongshore processes (typical of coastal plumes). Here field observations and numerical modeling are used to investigate …

The neuropsychology of sport concussion
… test battery in athletes using a longitudinal control group design. A single case study showed transient deficits in memory recall and executive function at one to six weeks post-concussion. The overall data suggest that (i) education is needed; (ii) the interchangeable terminology …

Shared decision-making and control between humans and adaptive control algorithms
This thesis addresses the problem of controlling a dynamical system subject to both parametric uncertainties and abrupt changes in the dynamic structure of the system, by proposing a shared control architecture predicated on a suitable division of responsibilities between supervisory human …

Perception-based synthetic cueing for night-vision device rotorcraft hover operations
… cue augmentation. Subjective ratings showed longitudinal control to be more difficult than in the other axes for both single and multi-axis control. This thesis demonstrates that artificial magnification of perceptual states through synthetic cueing can be an effective method of improving …
