Technique analysis in sports: a critical review.

This paper critically reviews technique analysis as an analytical method used within sports biomechanics as a part of performance analysis. The concept of technique as a specific sequence of movements appears to be well established in the literature, but ...

Improved optimization for the robust and accurate linear registration and motion correction of brain images.

Linear registration and motion correction are important components of structural and functional brain image analysis. Most modern methods optimize some intensity-based cost function to determine the best registration. To date, little attention has been ...

Automated breath detection on long-duration signals using feedforward backpropagation artificial neural networks.

A new breath-detection algorithm is presented, intended to automate the analysis of respiratory data acquired during sleep. The algorithm is based on two independent artificial neural networks (ANN(insp) and ANN(expi)) that recognize, in the original ...

Serial attention mechanisms in visual search: a direct behavioral demonstration.

In visual search, inefficient performance of human observers is typically characterized by a steady increase in reaction time with the number of array elements-the so-called set-size effect. In general, set-size effects are taken to indicate that ...

Simulation of the effects of global normalization procedures in functional MRI.

We report on differences in sensitivity and false-positive rate across five methods of global normalization using resting-state fMRI data embedded with simulated activation. These methods were grand mean session scaling, proportional scaling, ANCOVA, a ...

Effects of early mobility on shortcut performance in a simulated maze.

This experiment compared the shortcut choices of able-bodied teenagers with those of physically disabled teenagers who had varying histories of mobility impairment. In a computer-simulated kite-shaped maze, participants were allowed to explore three arms ...

A probabilistic explanation of brightness scaling.

The perceptions of lightness or brightness elicited by a visual target are linked to its luminance by a nonlinear function that varies according to the physical characteristics of the target and the background on which it is presented. Although no ...

Color interpolation algorithms in visualizing results of numerical simulations.

The paper addresses the application of graphical replenishment (GR) color interpolation algorithms for visualizing numerical simulation of physical processes in order to enhance the information density of the graphic interpretation of these processes. ...

Deformation of angle profiles in forward kinematics for nullifying end-point offset while preserving movement properties.

This work describes a new approach that allows an angle-domain human movement model to generate, via forward kinematics, Cartesian-space human movement representation with otherwise inevitable end-point offset nullified but much of the kinematic ...

The cerebellum in action: a simulation and robotics study.

The control or prediction of the precise timing of events are central aspects of the many tasks assigned to the cerebellum. Despite much detailed knowledge of its physiology and anatomy, it remains unclear how the cerebellar circuitry can achieve such an ...
