Body Motion Capture Using Multiple Inertial Sensors
… identify the latter, the movement of whole human body needs to be captured and displayed by a computer generated avatar. In this thesis, a wireless inertial motion capture system consisting of a central control host and ten sensor nodes is used to capture human body movements. Each of the ten …

Facet model optic flow and rigid body motion
… iterative and a non-iterative one, determine 3D motion parameters and surface structure (relative depth) from the computed optic flow field. Finally we discuss a technique for the image segmentation based on the multi-object motion using both optic flow and its time derivative. The facet model …

Energy Harvesting from Human Body, Motion and Surroundings
… possibilities in this space is the human body itself. Harvesting significant power from daily human activities will have a transformative effect on wearables and implantables. One of the main challenges in harvesting mechanical energy from human actions is to ensure that there is no effect …

INTERPOLATION OF RIGID-BODY MOTION AND GALERKIN METHODS FOR FLEXIBLE MULTIBODY DYNAMICS
Traditionally, flexible multibody dynamics problems are formulated as initial value problems: initial states of the system are given and solving for the equations of motion yields the dynamic response. Many practical problems, however, are boundary rather than initial value problems; two-point and …

A vector based approach for high frequency prospective correction of rigid body motion in Magnetic Resonance Imaging (MRI)
… The artefacts are dependent on how and when motion occurred, and manifest as ghosting, ringing and blurring of the image. This thesis describes a novel approach to measuring and correcting for motion as the data are acquired. A small device was constructed that combines observations from a …

Use of Computer Vision to Track Thin Body Motion with the Application of Tracking Passion Plant Vine Tendrils
… an algorithm set to track the vine tendril motion of a passiflora incarnate, commonly referred to as the passion fruit plant, to facilitate research into if there is a correlation between plant motion and plant health. An evaluation was done of clustering based color segmentation with a …

Examining the relationships between body motion gaming or mind-body practice and balance, cognition, and social engagement in community dwelling older adults
… being falls, frailty, and cognitive decline. Body motion gaming systems and mind-body practices have been successfully utilized to address balance, cognition, and social engagement in different patient populations. This study was designed to investigate if similar benefits could be seen in …

Estimation of 3D human motion kinematics model from multiple cameras
Estimation of articulated human motion based on video sequences acquired from multiple synchronised cameras is an active and challenging research area. This is mainly due to the need of high dimensional non-linear models to describe the human motion, cluttered data, and occlusions present in the …

Spatial coordination - human and robotic communicative whole-body motions in narrow passages
… communication via robotic and human whole-body motions in HRI. Humans have the natural ability to nonverbally communicate with each other via whole-body motion and are very able to interpret and predict motions of others, e.g., in order to coordinate themselves with others in narrow …

Noise transmission path identification in a reciprocating freon compressor
… pattern appears to be a combination of rigid-body motion of the compressor shell in response to the orbiting spring forces and a circumferential acoustic mode inside the shell. The sound intensity pattern radiated by a regular version of the same compressor model closely resembles the …

Dynamic Imaging by Motion Estimation
… object with periodic or quasi-periodic motion. Specifically, it has been shown that the proposed method can handle complex signal variations with localized motion, nonrigid-body motion, and motion in arbitrary directions. An important application of the proposed technique is …

Antarctic tabular icebergs in ocean waves
… geometry, structure and other features, rigid body motions and surface strains. We show that tabular icebergs respond to ocean waves of medium (15-30 s) and long (>30 s) periods, but that they act as filters to very short (<10 s) period waves. A two-dimensional, linear model of rigid body …

An estimation-theoretic technique for motion-compensated synthetic-aperture array imaging
… coherent processing to exploit the relative motion between an airborne or spaceborne radar antenna and the imaged target field (effectively synthesizing the effect of a larger aperture array). From an estimation-theoretic perspective, this thesis addresses the following limitations of …

Modeling and Slew-Maneuver Control of a Flexible Spacecraft
… a flexible spacecraft consisting of a rigid main body to which a long flexible appendage is attached. Nonlinear dynamical system models are developed using both distributed parameter modeling and discrete parameter modeling; these models are shown to be equivalent for appropriately chosen system …
