Dynamic Response of a Human Head to a Foreign Object Impact
This paper presents an analysis of a human head response to impact by a foreign object. The analysis is accomplished via an integration of a head-striker contact force function with a 3-D finite-element (FE) head model. The contact force function developed by the authors is used to estimate the contact force between the solid striker and the human head. An explicit FE solver, implemented with the ...Show More
A Non-Linear Model of the Neural Integrator in Oculomotor Control
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society
Year: 2007 | Conference Paper |
Cited by: Papers (1)
Neural integrator (NI) is presumed to exist in the oculomotor system to assist in numerous tasks such as maintaining gaze on imaginary targets in the dark. It has been widely accepted that the NI acts as a 'perfect' integrator even in the dark with time constants as large as 50 s. However, the NI time constant has been found to be much less than ideal and its value can also be dependent on context...Show More

Deformational plagiocephaly (DP) is an asymmetric flattening of the occiput, which can be caused by a preference for a sleeping position or a restriction of the head rotation. The absence of a standardized method to quantify the severity of DP is problematic, being the severity of the condition the main factor for the recommendation of a specific treatment. To improve the quality of assessment of ...Show More
