— This paper presents a coupled observer that uses accelerometer, gyrometer and vision sensors to provide estimates of pose and linear velocity for an aerial robotic vehicle. The observer is based on a non-linear complimentary filter framework and incorporates adaptive estimates of measurement bias in gyrometers and accelerometers commonly encountered in(More)
— This paper considers the problem of estimating pose from inertial and bearing-only vision measurements. We present a non-linear observer that evolves directly on the special Euclidean group SE(3) from inertial measurements and bearing measurements, such as provided by a visual system tracking known landmarks. Local asymptotic convergence of the observer(More)
The field of environmental health promotion gained new prominence in recent years as awareness of physical environmental stressors and exposures increased in communities across the country and the world. Although many theories and conceptual models are used routinely to guide health promotion and health education interventions, they are rarely applied to(More)

In the first three decades of life, more individuals in the USA die from injuries and violence than from any other cause. Millions more people survive and are left with physical, emotional, and financial problems. Injuries and violence are not accidents; they are preventable. Prevention has a strong scientific foundation, yet efforts are not fully(More)
2012 E very day in the United States, two dozen children die from an injury that was not intended. Such tragedy often leaves families broken apart and changes the lives of those left behind. Injury deaths, however, are only part of the picture. Each year, millions of children in the United States are injured and live with the consequences of those injuries.(More)
