Kinematics and Hydrodynamics of Cephalopod Turning Performance in Routine Swimming and Predatory Attacks
… study incorporates kinematic analyses of routine turning performance of brief squid <em>Lolliguncula brevis</em> and dwarf cuttlefish <em>Sepia bandensis</em> (Chapter 2), 3D velocimetry techniques to examine hydrodynamic turning performance of <em>L. brevis</em> (Chapter 3) and kinematic analyses …

Occulomotor Function and Locomotion in Parkinson's Disease
… Parkinson's disease: PD) experience difficulty turning that can lead to freezing of gait, falls, and an increased risk of fall-related injuries. We hypothesized, based on previous literature, that turning difficulty and freezing during turning may be related to deficits in the ability to switch …

Biomimetic oscillating foil propulsion to enhance underwater vehicle agility and maneuverability
… twisting turns, exceeding the best reported AUV turning performance by more than a factor of two; a minimum turning radius of 0.7BL, and the ability to avoid walls detected> 1.8BL ahead, are found for cruising speeds of 0.75BL/S, with a maximum heading rate of 400 / S recorded. Observations of …

The effects of vortex generating fins and jets on the crossflow separation of a submarine in a turning maneuver
… separation of a 688 class submarine in a turning maneuver was studied. The vortex generators are located on the top and bottom centerline of the submarine. The intent of the vortex generators is to improve turning performance by changing the hydrodynamic forces incurred from crossflow …

An investigation of the contribution of axial rigidity to turning deficits in individuals with Parkinson’s disease
Difficulty in turning is prominent in individuals with Parkinson’s disease (PD) and the resulting postural instability increases their risk of falling. Therefore, understanding the mechanisms underpinning turning deficits in PD is highly important for rehabilitation and fall prevention. The first …

Range and endurance modelling of a multi-engine aircraft with one engine inoperative (oei)
… causes several negative effects to a number of performance variables in addition to the loss of engine thrust. The range and endurance of an aircraft are directly related to the quantity of the fuel available and the fuel consumption rate. This thesis was conducted to investigate range and …

Dry land strength and power training to enhance swimming in-water turn performance
… impulse, in order to improve both swim start and turning performance. Elite swimmers demonstrate faster swimming turn times that are potentially a result of having better strength-power characteristics than sub-elite swimmers. The aim of this research was to quantify differences in dry-land and …

Dynamics and control of robotic aircraft with articulated wings
… This thesis covers some problems concerning the performance, stability and control of robotic aircraft with articulated wings in gliding flight. Speci cally, we are interested in aircraft without a vertical tail, which would then use wing articulation for longitudinal as well as …
