Dynamics and Control of Flexible Multibody Structures
… is to present a method for deriving equations of motion capable of modeling the controlled motion of an open loop multibody structure comprised of an arbitrary number of rigid bodies and slender beams. The procedure presented here for deriving equations of motion for flexible multibody systems is …

Slamming of High-Speed Craft: A Machine Learning and Parametric Study of Slamming Events
… of a deep-vee planing hull into waves, through a controlled motion slam into calm water. To provide a baseline to compare data from future controlled motion experiments to, a model drop experiment was completed to characterize the relationships of impact velocity and trim to slamming event …

Motion control of long span horizontal structures
… damping. These three properties traditionally controlled motion-related serviceability issues, but this is no longer the case. Engineers are increasingly reporting vibration problems in horizontal structures. Hence, the dominant design criterion has shifted from a basis of strength to one of …

Meta-Routing: Synergistic Merging of Message Routing and Link Maintenance
… to achieve Meta-Routing by controlling robot motion based on the radio frequency (RF) environment recognition method and gradient descent method. Mobile robot controlled motion can effectively improve network performance by driving robots to favorable locations with strong links. Moreover, the …

Slamming of High Speed Craft: A Parametric Study of Severe Cases
… envelope of high-speed surface vessels. The controlled motion experiments presented in this thesis were designed to be an intermediate step between vertical water entry tests of a wedge and a traditional tow tank experiment of a planning hullform in waves. This allowed a deeper study of the …

Development of Fine Motion Stages for Six Degree-of-Freedom Submicron Positioning
… the development and testing of a mechanical fine motion stage that uses a novel configuration of precision ballscrews and flexures to produce controlled motion in 6 degrees of freedom. The stage is designed to be capable of submicron repeatability within a range of motion that spans ±0.1 mm in 𝑥 …

Boundary condition effects on vibrating cantilever beams
… production and manufacturing, and precision of motion have made them attractive solutions to many controlled motion systems such as nanopositioners or linear platforms. However, in some applications the stiffness requirements for the devices to function properly and the stiffness requirements …

Biomechanical adaptations involved in ramp descent: Impact of microprocessor-controlled ankle-foot prothesis. Kinetic and kinematic responses to using microprocessor-controlled ankle-foot prosthesis in unilateral trans-tibial amputees during ramp descent
… amputees (TT) using a microprocessor-controlled ankle-foot prosthesis in active (MC-AF) compared to non-active mode (nonMC-AF) or elastically articulated ankle-foot device. A secondary aim was to determine the biomechanical adaptation made by able-bodied individuals when ankle motion …
