An Optimized Multiple Right-Hand Side Dslash Kernel for Intel Xeon Phi
… in the area of Dslash have focused on single right-hand side solvers. This thesis will present two optimized Dslash kernels which simplify vectorization using multiple right-hand sides and traverse lattices using novel methods. The speedups resulting from these approaches will be explored in …

Efficient projection space updates for the approximation of iterative solutions to linear systems with successive right hand sides
… of iterative solvers. In the case of successive right hand sides, it has been shown that accurate initial solutions may be obtained by projecting the newest right hand side vector onto a column space of recent prior solutions. We propose a technique to efficiently update the column space of prior …

The effect of left-hand training on piano performance
… this study was to determine the effects of left-hand training on piano performance among college students with no piano background. A pilot study and an expanded study were conducted over a two year period. Volunteers for each study were randomly assigned to either a control group or a treatment …

Prism adaptation in a case of cerebellar agenesis
… on two separate occasions, twice using his left hand, and once using his right hand. He wore prism goggles while pointing to a vertical line at each of nine target locations in baseline, exposure, and postexposure conditions. The position of his finger was recorded after each response. In the …

Optimization and Machine Learning Applied to Inverse Problems in Partial Differential Equations
… as well as one where the nonlinear term on the right-hand side is modified to include cubic or higher-order non-linearities. We show that these equations still possess traveling wave solutions. We then design parameter estimation/discovery algorithms for this system including a few based on …

Effect of Hand Dominance on Rate of Learning and Bilateral Transfer.
… generally have a dominant and a nondominant hand. Dominance refers to the ability to perform a task better with a particular hand [Hand preference does not necessarily mean hand dominance] (Rigal, 1974). For example, a child may show tendencies to be left hand dominant; however, his parents …

Restarting the Lanczos algorithm for large eigenvalue problems and linear equations.
… For linear systems with multiple right-sides, eigenvectors computed during the solution of the first right-hand side can be used to give much faster convergence of the second and subsequent right-hand sides. A restarted version of the nonsymmetric Lanczos algorithm is developed. …

Manual laterality in hearing impaired and hearing children
… was designed to investigate the differences in hand preference and skilled hand movement between hearing impaired and non-hearing impaired children. The subjects were 78 hearing impaired (44 males, 34 females) and 68 normal hearing children (24 males, 44 females). Hand preference was measured …

New geometric techniques for linear programming and graph partitioning
… program. As boundedness does not depend upon the right-hand-side vector, we run a modified version of the shadow-vertex simplex method in which we start with a random right-hand-side vector and then modify this vector during the course of the algorithm. This allows us to avoid bounding the …

An ODE solver for constrained state spaces: with applications to hybrid-system simulations
This thesis presents a solver to handle constrained-state-space ODEs. This solver locates the points where any of the states go outside of the constraining set, and then, transfers the control from the continuous time ODE to the function governing the behavior of the system on the boundaries of the …

Numerical solution of optimal control problems with implicitly defined discontinuities with applications in engineering
In the thesis on hand we treat optimal control problems for implicitly discontinuous dynamical processes. We give a general model formulation which includes implicitly given state dependent discontinuities in the right hand sides of the DAE system. The formulation is adapted to real-world …

Effects of Handedness on Completion Time during Performance of Multiple Tasks Using “Proper” and “Improper” Tools
<p>Handedness is a very critical factor involving single or multiple tasks that are designed for a specific hand. The purpose of this research was to investigate the effect of proper tool design. This research identified the dominant hand and measured task completion time between each of two tasks, …

Narrating Friendship: The reciprocal relationship between J.B. Childers and myself
… also doesn't exist. Childers who is naturally right-handed, painted everything left-handed because of a war wound, and so Engelmann, who is left-handed, painted with his right hand, which is quite a limitation." Of course, there's more to the story than that and the writings that follow will …

Efficient High Order Ensemble for Fluid Flow
… solving only one linear system with multiple right-hand sides for different realizations, reducing computational cost and simulation time. Four algorithms utilize a Generalized Positive Auxiliary Variable (GPAV) approach and are demonstrated to be second-order accurate and unconditionally …

Improving gesture recognition through spatial focus of attention
… that when spatial attention is focused on the hands, gesture recognition improves significantly, particularly when the channels are fused using a sparse network. We propose an architecture (FOANet) that divides processing among four modalities (RGB, depth, RGB flow, and depth flow), and three …
