Visual search strategy and interception accuracy
… of how visual search strategy and interception accuracy are influenced by constraints. Two experiments, manipulating spatial and temporal target motion configuration, assessed the role of constraints in interceptive aiming in interception accuracy and gaze control strategy. In Experiment 1, …

Rhythmic perception and entrainment in 5-year-old children
… I examine whether there is a link between the temporal processing required to process rhythmic entrainment in both phonological awareness skills and music. The data are interpreted with respect to a theoretical framework linking music and language based on temporal sampling. The ‘temporal …

Spatial and Temporal Performance Characteristics in a Two-Dimensional Human Motion Analysis System Using Digital Video Capture
… was developed to address system spatial and temporal performance characteristics in a two-dimensional (2D) human motion analysis system using commercially available digital video capture. The first testing protocol involved developing a method to evaluate system spatial performance …

Error analysis of higher order time-domain finite element methods for the one-dimensional Maxwell's equations
… method has been extended for higher order temporal accuracy using several schemes. While common in computational fluid dynamics, less research has been conducted with these methods for computational electromagnetics. A stabilized finite element method utilizing the Streamline/Upwind …

A high-order Legendre-WENO numerical scheme for the non-conservative kernel density equations modeling particle-laden flows
… are handled analytically. High-order spatial accuracy is achieved using a novel hybrid essentially non-oscillatory scheme with a Legendre basis. A standard WENO scheme is used by default, and a nonlinear mapping is introduced when needed to enforce physically relevant bounds in the solution, …

Facial hacking: the twisted logic of electro-facial choreography
… system inheriting its characteristics: i.e. temporal accuracy, consistency of execution and high programmability. How do we conceptualize the thinking about the human face as a digital computational display device? What are the implications of the “regime change” from neural to digital? The …

Highly scalable solution of incompressible Navier-Stokes equations using the spectral element method with overlapping grids
… lagged in time or extrapolated to higher-order temporal accuracy using a novel stabilized predictor-corrector algorithm. Matrix stability analysis is used to determine the optimal number of corrector iterations. Stability and accuracy are further improved with an optimal mass flux correction to …

Comparison of Charcoal and Tree-Ring Records of Recent Fires in The Northern Rocky Mountains, Kalispell, MT, USA
… few studies have been done on the spatial and temporal accuracy of these charcoal and pollen sediment strata analyses. In this study we created a dendrochronological fire history using fire-scarred trees in the watershed of Foy Lake in the Flathead Valley, MT, to determine the synchronicity …

Non-invasive Assessment of Swallowing and Phonation using High-density Electromyography
… within 10 minutes. A triggering system with temporal accuracy around 0.5 ms was created to enable precise comparisons between trials, subjects, and biomechanics. An automated signal processing framework was developed to efficiently process dynamic contractions across numerous muscle …

Optimization of airport terminal-area air traffic operations under uncertain weather conditions
… there exists a gap between the spatial and temporal accuracy of aviation weather forecasts (and existing capacity models) and what these algorithms assume. In this thesis we consider the problem of integrating currently available convective weather forecasts with air traffic management in …

Application of pressure-projection algorithms to a sharp projection immersed boundary method for the incompressible Navier-Stokes equations
… Navier-Stokes equations. While second-order accuracy in time and space is generally achievable for the velocity components, the pressure is usually first-order. To fully understand the source of this problem and the interplay between the pressure term and the overall fractional step method, …

Development of a 3D radial MR Imaging sequence to be used for (self) navigation during the scanning of the fetal brain in utero
… total number of projections improves the temporal accuracy of motion tracking at the expense of decreased signal to noise ratio in the navigator images. The effects of breathing and rigid body motion on image quality were also compared between 3D radial and equivalent 3D Cartesian …
