Maintaining privacy during continuous motion sensing
Mobile devices contain sensors which allow continuous recording of a user's motion allowing the development of activity, fitness and health applications. With varied applications, the motion sensors present new privacy problems which require protection. This dissertation builds on previous work …

Rigidity and invariance properties of certain geometric frameworks
… space Rn+l. We allow all its vertices to have continuous motion in the space, either in Rn+l or restricted in Rn. For a given k, based on certain rules, we separate all its k-faces into 2 groups. During the motion, we give the following restriction: the volume of the k-faces in the 1st group …

Farfalla: A poetry thesis
… this work in progress is seeking to be in continuous motion out of the confinements of poems to a place where purposes are real and methods are issues of morality. By dealing with personal and political I am being faithful to the temporal, hence moving (as dictated by time) the poems are …

Investigating the angle or response and maximum stability of a cohesive granular pile
… I examine the transition from stick-slip motion to continuous motion as well as the effect of viscosity on the angle of repose of the granular pile. I offer a qualitative explanation for my observations of these phenomena.

Whole Skin Locomotion Inspired by Amoeboid Motility Mechanisms: Mechanics of the Concentric Solid Tube Model
… the need for alternative fundamental locomotion mechanisms for robots that allow them to maneuver into complex unstructured terrain becomes critical. In this research we present a novel locomotion mechanism for mobile robots inspired by the motility mechanism of certain single celled …

Terrain Impostors
… movement of the viewing position is limited to continuous motion and restrained to a known speed, many terrain features may be rendered once in high detail and reused for several frames.</p> <p>This thesis proposes a method to increase the rendering speed of large complex terrains by splitting …

Gait Phase Estimation and Foot Trajectory Prediction During Dynamic Walking Using Gated Recurrent Units
… with the wearer for a more natural, uninhibited motion. While previous studies have focused on predicting continuous motion, they often overlook critical transitions between walking and standing, which are essential for natural locomotion. We propose in this study a foot trajectory prediction …

Investigation of Toughening Mechanisms in the Fracture of Asphalt Concrete Using the Clustered Discrete Element Method
… to handle numerically due to the creation and continuous motion of new surfaces. A clustered discrete element method (DEM) is employed as a means to investigate fracture mechanisms in asphalt concrete at low temperatures. A bilinear cohesive softening model is implemented into the DEM framework …

Physically Interacting With Four Dimensions
… of this research is to exploit the free motion of a computer-based haptic probe to support a continuous motion that follows the \emph{local continuity\/} of a 4D surface, allowing collision-free exploration in the 3D projection. In 3D, this interactive probe follows the full local …

Visual perception of social groups in zebrafish
… number of elements, speed and overall amount of motion - might influence shoaling behaviour and be integrated within a dorsal thalamic circuit for the detection of social cues. I show that visual motion cues alone are sufficient to elicit attraction and a preference for larger groups, and that …

Development of X-ray Coherent Scatter Projection Imaging Systems
… five 33.2 keV pencil beams in combination with continuous object motion. The system consisted of a primary collimator, motorized stages for object translation, a flat-panel x-ray detector for measuring scattered x rays, and discrete photodiodes for simultaneously measuring transmitted x rays. …

Structural Studies into the Mechanism and Organisation of Mammalian Respiratory Complex I
… interface is highly flexible and undergoes a continuous motion likely to support the structural or mechanistic costabilisation of respiratory complexes. In summary, this work explores complex I and III2 structure and interplay in a pathologically relevant and metabolically unique system. …

Optimization Techniques for Trustworthy 3D Object Understanding
… Temporal constraints enforce rigidity and continuous motion. Despite the non-convexity of this problem, we solve it to certifiable optimality using a smallsize semidefinite relaxation. We also present a compatibility-based outlier rejection scheme to handle outliers, and evaluate the …

Motion coordination and control in the development of a gait rehabilitation system
… trajectories that limit the joints' range of motion (ROM) thus improving the gait training safety. The movement of the input links of gait generation mechanisms must be controlled to provide proper timing of both stance and swing phases during a training session. This research describes the …

Is Hamlet untranslatable? : renegotiating the boundaries of translatability in twentieth century German Hamlets
… whereas Hamlet is semantically and formally in continuous motion and resists attempts at closure. The demands of translation and the nature of Hamlet seem to be in direct conflict, and I begin my investigation with a hypothesis that Hamlet is 'untranslatable'. I have conducted a series of …

Leveraging Geometric Priors for In-the-wild Pose Estimation and 3D Reconstruction
… relationships, and inferring 3D geometry or motion. However, interpreting visual data is challenging due to occlusions, limited viewpoints, and the partial nature of sensor observations, which make many real-world perception problems highly ill-posed. While deep learning methods have been …

Flexible polyhedra - Exploring finite mechanisms of triangulated polyhedra
… is physically possible; then a range of motion is defined between occurrences of clashes at the two ends; finally, an optimisation tool is used to maximise the range of motion. By using these tools, the range of motion of two types of simplest flexible polyhedra are maximised. The first …

Optimization of Image Guided Radiation Therapy for Lung Cancer Using Limited-angle Projections
… This technique acquires the same traditional motion-blurred on-board DTS image as the 3D-DTS technique, but uses the planning 4D computed tomography (CT) to synthesize a phase-matched reference DTS to register with the on-board DTS for tumor localization. Of the 324 different scenarios …
